So I started by adding the ability to define syllable structure in the rules file, then I tried running the syllable rule through the same compiler I used for the regular sound change rules. It ended up being even slower than I was anticipating, so I decided to skip the NFA to DFA conversion step and wrote a backtracking NFA runner. This worked _okay_, but if the syllable rule isn't able to fully match a word it ends up backtracking forever, and I never managed to figure out how to fix that.
Last year I read a post about parser combinators and I decided to rewrite the syllable detector. I finished the rewrite and then ran into an error and gave up. This last weekend I revisited it and it turned out it was just user error again; my syllable definition rule had a mistake, but thankfully the error was a lot easier to fix with the new design. Now it emits a warning, and I'm rewriting my sample sound changes rules to use the new boundary markers and hammering out any issues, which are a lot less than I was afraid of.
I'm thinking about rewriting the sound change rule compiler to use the same combinators I did for the syllable rules, but it would be kind of a shame after all the work I put into the DFA compiler lol
Models are the new software. And just like software, three general-purpose ones won't be enough. Why specialized models are inevitable https://mixtrain.ai/blog/special-models
Here's how Mixtrain can help:
- Multimodal dataset management: version, query, inspect, and curate image/video/3D datasets
- Workflows & models: train and run your models on serverless GPUs. Run experiments rapidly and ship to production. Access 100s of external models through the same API.
- Live eval: create instant evals from your datasets with side-by-side comparison of anything — images, time-synced video, 3D/4D visualizations, masks, and more. Here's an example video eval https://app.mixtrain.ai/s/eVRwOcb7KhUZOb9xbFFgfHIuF0jyJUaBT6TKNg19OfU. Evals stay current as your datasets evolve.
I have also taken an interest in learning distributed paradigms like MPI and am using it on my own cluster of rPis
Interesting findings include Mistral doing better than Gemini 3 Pro in certain usescases, cross-LLM works better than one LLM to another, oh and - the cost all of of this. So, so expensive.
My favorite output so far is that I asked it what life was and in a random stroke of genius, it answered plainly: "It is.".
It's able to answer simple questions where the answer is in the question with up to 75% accuracy. Example success: 'The car was red. Q: What was red? ' |> 'the car' - Example failure: 'The stars twinkled at night. Q: What twinkled at night? ' |> 'the night'.
So nothing crazy, but I'm learning and having fun. My current corpus is ~17mb of stories, generated encyclopedia content, json examples, etc. JSON content is new from this weekend and the model is pretty bad at it so far, but I'm curious to see if I can get it somewhere interesting in the next few weeks.

Need to gather more patterns then create tooling around making it easier to use.
The goal is to raise the quality of comments/posts in forums where the intent is productive discussion or persuasion.
I'm still playtesting it with friends and it's been fun. It's in early access, I don't feel right charging for it unless other folks actually end up liking it and thinking it's fun. If you sign up, send me a message through "Send Feedback" (or here!) and let me know if you like, but especially let me know if you hate it.
Today, if you search for "what size should I get in Nike Air Max 90" you'll find size charts. We have it, and for 200+ brands across 70+ retailers. When users tell us which shoes they own and what size fits them we’re slowly building crowdsourced fit recommendations which are personal and more accurate compared to size charts.
We're two coders who've built an almost fully autonomous platform. AI agents build, debug and deploy crawlers on their own. We went from 4 crawlers to 280+ in about a month, and the whole thing runs on a home server. When new shoes are discovered, the platform publishes new pages with relevant info automatically. Agents get access to platform metrics and SEO data via custom MCPs to identify the right opportunities on their own. Currently at about 3000 MAU and about 100 size recommendations/day.

Managing our above ground pool this summer and small hot tub in winter and continually asking "why isn't this easier" led to the development of Pool Pilot. Scan a test strip with your camera, water care recommendation checklist generates and you can order more supplies if needed easily from Amazon. Basically met my personal need and hoping it will help others too.
The fun technical bit: test strip chart colors can vary by manufacturer and even between production batches, but, the specific color chart that comes on a bottle should be accurate to those specific steps. Additionally, test strip colors are notoriously hard to match from photos. RGB comparison falls apart with lighting changes. After many interesting and considerations we calibrate of the specific test strip bottle and we use LAB color space and Anthropic's Claude vision model to read strips directly. This has worked exceptionally well in our testing and works with any brand;
The app also offers timers, history and much more. It has become a minor obsession.
React Native/Expo, Firebase backend, $10/year after 3 free tests (early tier pricing). Would love feedback from any fellow pool or hot tub owners.

It was inspired by tamagotchis of yesteryear (and my two cats). It uses a small common monochrome SSD1306 display with 128x64 pixels of resolution.
All of the pixel art is my own. And the cat features a bunch of different animated poses and behaviors, as well as different environments. And there are minigames (a chrome dino clone - but with a cat!, a breakout clone, a random maze generator, a tic-tac-toe game, and I plan to add more.)
I'm currently working on tweaking the stats so that they go up and down over time in a realistic way and encourage the player to feed and interact with the pet to keep stats from going too low. Then I plan on adding some wireless features, like having the pet scan WiFi names to determine if its home or traveling, or using ESP-NOW to let pets communicate with each other when they're nearby.

The original Python icloudpd is looking for a new maintainer. I’ve been building a ground-up Rust replacement with parallel downloads, SQLite state tracking, and resumable transfers. 5x faster downloads in benchmarks, single binary, Docker and Homebrew ready.
Today - Parsing a website's HTML (lots of pages, lots of links) to update an RSS feed that accepts filters. Rather than manually checking a website and losing track of what I have or haven't reviewed, the idea is to feed it into an RSS aggregator.
I started it because I wanted a CAD I would actually enjoy using myself. The idea is a simpler, assembly-first workflow instead of a full engineering CAD.
It’s still very early and rough, but I recently got the first real loop working: model → export STL/STEP → slicer → 3D print.
The goal is something between Tinkercad and the big CAD tools - simple, local-first, and not locked behind subscriptions or cloud accounts.
We got tired of bouncing between a note-taking app and a task tracker. Notion combines them but it's slow and its offline capabilities are limited. Linear is fast but tasks-only. Obsidian is local-first and e2ee but single-player. So we're building Notello - notes and tasks in one deeply nestable tree, real-time multiplayer, works offline, e2e encrypted.
Reads/writes hit local SQLite first, sync happens in the background. That way everything is instant, you don't notice the network except in some very special use cases. Runs on web and desktop with shared core logic.
We're building it for powerusers like us who want IDE-like navigation, block editor, control over their data, granular sharing down to individual entries and more. Your work workspace and personal workspace live side by side, no switching workplaces.
Old website that needs refreshing (we failed to build it beyond an MVP a decade ago but armed with more experience, we're giving it our best this time): https://notello.com . Launching within the next few months!
= Proofreading =
https://github.com/adhyeta-org-in/adhyeta-tools
provides image extraction from PDF, OCR as well as a basic but nice proofreading web-ui.
Qwen 3/3.5 is good enough for OCR on books in Indic scripts. So that is what I am using. But you can configure the model that you want to use.
I may add a tesseract back end as well if necessary.
= Language Learning =
I have tried a few parallel text readers and was not satisfied by any of them. My website (https://www.adhyeta.org.in/) had a simple baked-in interface that I deleted soon after I developed it. However, this weekend, I sat down with Claude and designed one to my liking. I also ported the theming and other goodies from the website to this local reader. This will serve as a test bed for the Reader on the website itself.
LLMs now produce wonderful translations for most works. You can take an old Bengali book, have Claude/Gemini OCR a few pages and then also have it translate the content to English/Sanskrit. Then load it into the Reader and you are good to go!
The Reader, I will release this month. Claude is nice, but I do not like the way it writes code. It often misses edge cases and even some basic things and I have to remind it to do that. So I want to refactor/rearrange some stuff and test the functionality end-to end before I put it online.
Over the past weeks, we consistently get 5-6 submissions per week. The newsletter and number of visitors are growing.
I’ve come to treat this as a pet project but realized that for indie devs who get very little marketing attention, being featured in the newsletter, top of the daily list, etc. can be another burst of users.
Ps: i dont like the term “AI sre” but its what people call it…
The hypothesis is that llms are better off getting the "big picture" by reading local files. They can then spend tokens to edit the document as per the business needs rather than spending tokens to figure out how to edit the document.
Another aspect is the security model. Extrasuite assigns a permission-less service account per employee. The agent gets this service account to make API calls. This means the agent only gets access to documents explicitly shared with it, and any changes it makes show up in version history separate from the user's changes.
Early release can be found over here - https://github.com/think41/extrasuite.
The core is pure JavaScript with zero dependencies. It works in Lab color space (not RGB) using Wu quantization, CIE perceptual distance metrics, and a DNA fingerprinting system that matches each image to one of 20+ built-in archetypes (Golden Hour, Dark Portrait, Fine Art Scan, etc.).
There's a browser-based web UI that just needs Node.js — drop an image, get 4 different possible separations side by side, export as layered OpenRaster (for GIMP/Krita), or flat PNG, or layered PSD (for Photoshop). There's also a CLI and Photoshop plugin.

It's gone a long way to solve the "review" bottleneck people have been experiencing (though admittedly it doesn't fix all of it), and I'm in the process of adding support for Mac and Windows (WSL for now, native some other time).
Some of the features I've had for a while, like multi-project agent worktrees, have been added as a part of the Codex App, so it's good to see that this practice is proliferating because it makes it so much easier to manage the clusterf** that is managing 20+ agents at once without it.
I'm feeling the itch to have this working on mobile as well so I might prioritize that, and I'm planning to have a meta-agent that can talk to Tenex over some kind of API via tool calls so you can say things like "In project 2, spawn 5 agents, 2 codex, 2 claude, 1 kimi, use 5.2 and 5.4 for codex, use Opus for the claudes, and once kimi is finished launch 10 review agents on its code".

* adding local conversation memory for LLM
* improving Word spec compliance
* adding/extending table and image manipulation
* bug fixes!
The problem: every agent framework bolts together a vector DB for recall, a KV store for state, maybe a graph DB for relationships, and then hopes the duct tape holds. You get one retrieval path (similarity search), no decay, no consolidation, and the agent forgets everything the moment context gets trimmed.
HEBBS replaces that stack with a single embedded binary (RocksDB underneath, ONNX for local embeddings). Nine operations in three groups: write (remember, revise, forget), read (recall, prime, subscribe), and consolidate (reflect, insights, policy). The interesting part is four recall strategies — similarity, temporal, causal, and analogical — instead of just "nearest vector."
Some technical decisions I'm happy with:
- No network calls on the hot path. Embeddings run locally via ONNX; LLM calls only happen in the background reflect pipeline.
- recall at 2ms p50 / 8ms p99 at 10M memories on a 2 vCPU instance.
- Append-only event model for memories — sync is conflict-free, and forget is itself a logged event (useful for GDPR).
- Lineage tracking: insights link back to source memories, revisions track predecessors.
SDKs for Python, TypeScript, and Rust. CLI with a REPL. gRPC + REST.
There's a reference demo — an AI sales agent that uses HEBBS for multi-session memory, objection handling recall, and background consolidation of conversation patterns.
Still early. The part I'm wrestling with now is tuning the reflect pipeline — figuring out when and how aggressively to consolidate episodic memories into semantic insights without losing useful detail. Curious if anyone working on agent memory has opinions on that tradeoff, or if you've found other approaches that work.

It incorporates also complaints from a static analyzer for Python and Javascript that detects 90+ vibe slop anti-patterns using mostly ASTs, and in some cases AST + small language models. The complaints give the local class and methods a sense of how much pain they are in, so I give the code a sense of its own emotional state.
I also build data flow schematics of the entire system so I can visualize the project as a wire diagram, which is very helpful to quickly see what is going on.
That would probably motivate me to fix the poor thing, just so I don't feel like I'm torturing it! :-D

even with everyone and their mother shipping a workout app (accelerated by the vibecoding surge), nothing quite hit the bar i was looking for. everything seemed to be built in react native, flutter, or another cross-platform framework, meaning it never truly felt at home on the device.
beyond just wanting something fully native, i felt there was a real gap in the prosumer market. i wanted to build something for people who already know what they're doing in the gym, have their program, and just want a solid tool they can actually own (it's a one-time purchase of $12.99) that at the same time gives them all the insights they'd reasonably want (muscle heatmap, 1rm breakdowns with different formulas, working volume, best volume, etc.).
the app is called Plates: Weightlifting Log. if you're interested in checking it out: https://useplates.com
https://www.appsoftware.com/products/knowledge-management/as...
It implements [[wikilinking]], backlinking, task management into VS Code. The idea is to bring Logseq / Obsidian capability to VS Code.
The blurb:
If you already live in VS Code, why manage your notes somewhere else? AS Notes brings the power of wikilink-based knowledge management - the kind you'd find in Obsidian or Logseq - directly into your editor. No Electron wrapper. No separate app. No syncing headaches. Just your markdown files, your Git repo, and the editor you already know.
Why AS Notes? Your data stays local. No cloud sync, no telemetry, no accounts. Your notes are plain .md files in a folder you control. Git-friendly by design. Every note is a .md file - diff them, branch them, review them. Your knowledge base gets the same versioning discipline as your code. Lightweight. A local SQLite database (powered by WASM - no native dependencies) keeps everything fast without bloating your workspace. Key Features Wikilinks Type [[ to trigger page selection and autocomplete. Links resolve to .md files anywhere in your workspace - not just the current folder. If the target doesn't exist, it's created automatically, useful for forward-referencing pages you plan to write later.
Renaming a page offers to update every reference across your workspace. Hover tooltips show the target file, whether it exists, and how many other pages link to it.
Backlinks The Backlinks panel shows every page that links to the file you're currently editing, with surrounding line text for context. A straightforward way to see how ideas connect across your knowledge base.
Open it with Ctrl+Alt+B - it stays in sync as you navigate between files.
AS Notes Backlinks Task Management A lightweight task system built on standard markdown checkboxes. Press Ctrl+Shift+Enter on any line to cycle through states (unchecked → checked → plain text). The Tasks panel in the Explorer sidebar aggregates every task across your entire knowledge base, grouped by page - filter to show only unchecked items, or toggle completion directly from the panel.
Page Aliases Define aliases in YAML front matter so multiple names resolve to the same page. [[JS]] and [[ECMAScript]] can both navigate to JavaScript.md. Backlink counts include alias references, and rename tracking updates aliases in front matter automatically.
Daily Journal Press Ctrl+Alt+J to create or open today's journal entry. AS Notes generates a dated markdown file from a customisable template - add your own sections, prompts, or front matter to shape your daily workflow. Journal files are indexed instantly, so wikilinks and backlinks work from the moment the file is created.
AS Notes translates nested wikilinks when rendering markdown previews so links navigate correctly. Works alongside other markdown extensions - Mermaid diagrams, for example.
Also a bunch of other smaller projects and ideas.

After being a web-focused dev for my whole professional career, I am now developing a mobile app with Flutter.
The app is called Limberly, and it focuses on health and ergonomics for sedentary workers. Us, who sit for a living.
It is scientifically proven[1] that sitting is detrimental to our health, with increased mortality rates. The primary way to reduce the negative effects of sedentary work is to move, and scrolling through feeds on your phone doesn't count as moving :)
This means performing sessions of resistance training, running, biking, but also taking micro-breaks during work sessions.
Research has shown[2] that taking short breaks during work reduces fatigue, and in some cases boosts performance.
Limberly is still in early development, so it's basically a glorified collection of timers (for taking microbreaks, for switching between sitting and standing, and for switching your "mouse hand"), but I do have a clear vision of having a smart system that recommends specific activities to do during breaks, ergonomically setting up your workspace, coach you on correct posture, track statistics etc.
If you'd like to help me test and shape the app as we go, please sign up for the waitlist or DM me here.
P.S. I guess this is a required disclaimer these days: The landing page is static and mostly vibe-coded, but the app itself is not. I do use Claude Code to speed up certain plumbing and widget implementations, but the core architecture and logic are designed, vetted and programmed by myself. Being a solo dev, it is important for me that I understand what every class and function is doing.
P.P.S. I don't like using scare tactics like "SITTING IS KILLING YOU!!" but it is sadly a fact. Also, I'm not selling you anything, as the app is free to use :)
Investing in standing desks, HM chairs and split keyboards is definitely a good idea, but what matters most is movement and changing your pose constantly.

Tech details: I found that used, small form-factor Dell Optiplexes are great for product protoytyping. I'm in Medellin Colombia, and found that you can buy these for about $200 USD - they are often former Point of Sale (POS) or office computers, from about 10 years ago. They have SSDs, run quiet, and are very reliable.
For project Affirmator, I installed Linux Mint Debian Edition (LMDE). Using Cron and Mpv to shuffle-play activity-specific folders of MP3s at the same time each day. For example, for the chill jazz music - I've got a folder of 40+ song MP3s. Cron plays those at 06:30. So it's like a calm, upbeat alarm clock. I'm not a morning person, so this is a "friendly" way for me to wake myself up!
For the vocal affirmation part - I built a Python tool that reads 200+ text affirmations from a markdown/text file. It then uses AWS Polly text-to-speech API to vocalize the affirmations into MP3s. Next, I use `ffmpeg` to add a variable silent spacer gap to the ends of all the MP3s. This allows your to hear a voice affirmation ("I am fit, athletic, and strong!", "I am a confident piano player."), and then there is silent space for you to say it out loud, or repeat in your head.

Translates the word & example phrases to English / Spanish / Chinese. Uses Text-to-speech to vocalize the phrases into each language. These phrases are ordered by frequency. When you want to improve your language skills, you set a "window" range of frequency you want to practice, and Lingofreq will play audio files in this range. You can learn Chinese & Spanish while doing the dishes, at the gym, or before going to bed!

Documenting my Knowledge as "Public Knowledge Base" - https://codeberg.org/jro/Knowledge - Here are my notes on Python, Git - I'm bouncing between Obsidian Sync / Publish / Markdown (currently easiest way), and some sort of open-source knowledge base website (VSCodium + Markdown + FOAM + MkDocs + RClone). I haven't found a solution I'm happy with yet...
Open-source CNC router tech stack: - I have a CNC router (robotic drill which can carve 3D shapes into wood). Last year I challenged myself to operate it completely through an open-source tech stack. This took me on a journey of learning Inkscape (2d vector design tool, SVG), FreeCAD (3D product design / CAD / CAM tool), G-code (format of text instructions which tell CNC tools where to move and what to do), Universal G-Code Sender (a tool which imports CAM - computer aided manufacturing - designs, connects to the CNC router tool, and actually operates machine. It's quite exciting to play with! Used Kiri-moto (web-based CAD / CAM tool) to convert 2D/SVG designs into 3D shapes). Used OBS (screen recording/streaming tool) and a bunch of web-cams to live-stream tool usage to PeerTube Live (similar to YouTube).
Being "principled" about using open-source tools can be so challenging, but its quite rewarding on the long run.
LEARNING SPANISH - What's working for me... trying to read spanish books before bed. Handwriting a few paragraphs from a book into journal. Highlighting words I don't know. Looking them up later. Reading a book while listening to its audio book at the same time.
If anyone's interesting in contributing to these projects, I would warmly welcome that. Design, product, sales, project management, engineering/coding, marketing - need tons of help in all these areas.
Gracias! // JRO
Been a project I was using for a few years now. Initially started off as express middleware with a few tools chained together to automate as much typing as possible which can run anywhere (similar to hono).
Around a year ago I decided to change the approach and write a layer to statically analyze the typescript code ontop of tsc and pull out as much meta as possible.
After that I went a little crazy and ultimately added wires to everything. HTTP, Websockets, Queues, Scheduled Jobs, etc. All totally agnostic (the core runtime is pretty tiny). So can run scheduled tasks on lambas / a cron job / pgadmin, deploy websockets serverless or local, run your queues again most queue provides, etc.
I then saw Vercels workflow runner and figured, well, I could try do better . Looked at other libraries out there and decided to include addons, which are pikku typescript packages that declare functions which can be automatically imported into your app and are responsible for their own service initialization. If your used to writing n8n plugins be awesome to hear what you think about this approach!
That sort of required me to create a console to view workflows (otherwise what's the point right?). And since everything is statically extracted during runtime we can pretty much just visualise the entire codebase. So all your functions, what permissions each have, etc etc. The idea behind the console is that it doesn't have an actual backend. You install an addon into your own codebase, permission it as you see fit and you point the console towards it. That means you have a unified permissions/auth system as everything else.
Figured the last part was creating an AI agent to wrap it all together. Which is almost there. Subagent flows, tools, approvals, ai middleware that can turn input and output into voices, its does a bit.
Ultimately the idea is you write a function once, and it can be consumed as an AI tool, a workflow step, by a http route, a cron job, a gateway (like whatsapp) (I liked openclaw approach so figured.. why not ).
A function is the source of truth, so is permissioned / authenticated. Been alot of heavy development since I'm building a 'BuildYourAgent' portal ontop that pretty much takes an openapi doc and turns it into an MCP server / hooks it up to an agent / gives you a CLI around it so it can integrate with all the crazy wild west approaches, while you know, still allowing us to maintain sanity and build servers that don't hallucinate and burn forests down.
Curious on thoughts! Bit of a rambling explanation. I hope the website does a better job! Lots of content helped with AI (I prefer speaking tech, but doesn't always transition well).
Also, looking for a potential cofounder to help balance that out! If your interested in potentially working together / adopting pikku feel free to leave a comment / ping me an email
I'm also publishing a hackernews daily digest.
This story was included in the March 9th issue (https://hn.alcazarsec.com/daily?date=2026-03-09).
Hacker News users are currently developing a diverse range of projects, from a retro-inspired city builder game [0] and an award-winning daily word puzzle [4] to a European-based search engine alternative [2] and a NSFW filter for the Marginalia search engine [8]. Several developers are focusing on practical tools for family and personal life, including an educational site to help relatives identify AI-generated content [1], a "statphone" for emergency family alerts [3], and a local-first financial tracking app using double-entry accounting [6]. Others are experimenting with advanced technical implementations, such as using LLM agents to backtest stock trading strategies [5], "vibe-coding" CLI tools, and designing a new language for bare-metal embedded devices [7].It's written in Golang and acts as a simple desktop app that creates a web server and then opens the site in your default browser. This way it's easily multi-platform and can also be hosted as a SaaS for larger production houses.
Our thesis is that a lot of Data Engineering practiced today is non-differentiated across companies and they'd rather spend that time on differentiated tasks. What if we can abstract away a lot of the tedious parts of DE work and let companies focus on just the data they want to store, and the questions they have on their data?
So today, we have an MVP that manages the compute, storage, lineage, versioning and pipeline building for datasets. Would LOVE to get feedback on this or your early thoughts!

However, to access those, you either have to use Stripe Sigma or pull them from the API. I wanted to build a more convenient way to access those (and also act upon them).
I've submitted the app to Stripe's App Marketplace, but I have a limited number of test invites to send out if you're interested (I will happily waive your subscription for 3 months).
Arch Asxent https://github.com/mikko-ahonen/arch-ascent - tool for analyzing large microservice networks with hundres of microservices and creating architectural vision for them, and steps to reach the vision
I went through the Software Architecture Patterns for Serverless Systems book, which I think it is fantastic. I learned a lot but I still had a lot of doubts to actually use the ideas in real life. So I started dissecting the companion framework, which is in written in Typescript. I have been going piece by piece and converting to Kotlin which I think it is more expressive (and fun) and it is allowing me to understand how everything fits together.
Typescript framework: https://github.com/jgilbert01/aws-lambda-stream
It has a visual query builder and separate SQL tutorial.
https://talonwatch.com : I kept seeing founders discover their Stripe keys were public or their database was wide open, usually after the damage was done. Built a passive security scanner for vibe-coded apps so that's easier to catch early. Free surface scan, no account needed.
https://thetracejournal.com : A small iOS journal that pairs a song with each entry. Music is tied to memory in a way nothing else is, and I wanted a place to capture that.
A problem that we had at my last startup was that we got stuck between not wanting to spend too much time on devops, and getting price gouged by Heroku.
We were too big for the deploy to a VPS type options like coolify, but too small to justify hiring a full time Devops.
Eventually a few of us had to just suck it up and learn Kubernetes properly. Was pleasantly surprised how elegant it all was.
I was surprised there wasn’t something that “just worked” and plugged into our Kubernetes cluster, made it user friendly, teams, roles, etc.
Building FoJin (https://fojin.app) — an open-source platform that
aggregates Buddhist digital texts from 440+ global sources (CBETA,
SuttaCentral, BDRC, SAT, 84000, GRETIL, etc.) into one searchable
interface.
Stack: React + TypeScript, FastAPI, PostgreSQL with pgvector,
Elasticsearch 8 (ICU analysis for CJK), Redis. Features include a
knowledge graph (9,600+ entities), 237K dictionary entries, full-text
reading of 4,488 fascicles, and RAG-powered AI Q&A grounded in 11M
characters of canonical text.
GitHub: https://github.com/xr843/fojin1 - actual css static analysis -- consume html + css, and provide tooling to preview what properties are inherited given the context you're in -- what you're overwriting, what display mode you're in. If there's inconsistent display modes depending on where in the html you are.

i only have prototypes, and unfortunately given the climate i feel i am the only person who wants these tools.. but every few weeks i get to sit down and get some progress and that's nice
The server is a rust binary so you can toss it on any container/computer and connect to it in the app.
My philosophy isn't to replace my other tools I love like emacs, ghostty, etc. But I am taking a stab at "real time code review" and have some crummy magit-like code review built in that I need to revisit.
Stack is React frontend, Node.js backend, Claude as the primary AI layer for orchestration.
The most interesting engineering problem has been the orchestration layer. Getting an agent to handle multi-step outbound workflows with real judgment, not just automation, takes a lot of iteration on the prompting and state management side. Also feedback from users on the best workflows to collaborate with agents.

It is based on 20+ years of experience maintaining a similar system in Perl.
It's on Hex.pm already, looking for people to test and comment!
As Codex would say:
Selecto is an open-source SQL query builder for Elixir that helps you generate complex queries from clean, domain-based configs. It supports advanced joins, CTEs, subqueries, and analytics-friendly patterns, with companion packages for LiveView interfaces (selecto_components) and code generation (selecto_mix). If your app is data-heavy, Selecto gives you SQL-level power without brittle hand-written query strings.
Bringing back the hobbyist self-made PCB workflow since it can be a headache to get designs back from PCBWay / JLC between customers, tariffs, shipping..get more quick to close the prototyping loop.

It's a budgeting app I'm building for iOS and Android. It's an alternative to YNAB, Goodbudget, or Monarch, but the checking account and debit cards are built-in, so it avoids the unreliable syncing issues that make budgeting apps suck. It's named after the digital envelope system and helps you organize money into categories for bills, spending, savings, upcoming expenses, etc. Individual and joint accounts.
Right now I'm working on an upcoming paycheck detection system to automatically split your paycheck across your budgets.
I needed a way to use and push my own artifacts in Meson projects. WrapDB is fine for upstream deps, but I wanted to publish my packages and depend on them with proper versioning and a lockfile, without hand-editing wrap files.
Collider builds on Meson’s wrap system: you declare deps in collider.json, run collider lock for reproducible installs, and push your projects as wraps to a local or HTTP repo. It’s compatible with WrapDB, so existing workflows still work: you just get a clear way to use and push your own stuff. Apache-2.0.
Been learning dance moves from TikTok but hated the pause/rewind loop on my phone. So I built a web app that overlays the original dancer as a translucent ghost directly on your camera feed.
Upload any video → ghost appears → you follow → record yourself → export. No install, works on mobile browser.
Feedback will be much appreciated!

I am working on Entangle, https://entangle.cloud something for me to learn and play with LLMs and AI.
It is not ground breaking but let your website to have an AI chat bot / agent with minimal integration effort. Also was a good way for me to learn how to keep things safe, prevent prompt injection etc.
Looking for feedback and feel free to give it a try, happy to try it with your project documentation or developer docs.
(Sign up and I’ll send out beta codes tomorrow!)
I’ve had a few friends call it “fun”, and one said it’s “Scrabble that doesn’t drag”.

To accomplish this, I built a snow metamorphosis model that forecasts what the snow surface skis like, a dataset of resort "topography", and an optimizer that gives skiers an idea of how to best structure their day.

Today engineers spend dozens of hours agonizing over how to unlock the vast analytical possibilities of JSON data in their warehouse. The internet is littered with half solutions and broken promises. Today, we have solved this problem.
Several readers have asked for an easy way to get recommendations without working through long-form review articles.
Here's the first iteration of a simple recommender: https://bcmullins.github.io/reading/
i have also started experimenting with qwen3.5 0.8B model, my goal is to create agents with small models that are as robust as their commercial counterparts for specialized tasks. currently trying it for file editing.
I just released support for dashboards. I've kept a devlog for the past 6 months.
And the biggest update is coming soon, DB Pro Cloud, which will let you connect to and manage any database through your browser as well as collaborate with your team.
Imagine Postman but for databases.
A lot of demos work well in prototypes, but once you try running agent-based workflows in production you start seeing issues around orchestration, tool reliability, latency, and cost control.
So I've been putting together some architecture patterns and real-world approaches teams are using to make these systems more reliable in production environments.
It also features a recipe manager with family/friends sync. This makes it possible to upload your grandmother’s cookbook and share them with your whole family.
While working on another project, I needed a very simple service I could setup in a few clicks, which would take my docker compose and manage the spin up and tear down of ephemeral VM automatically when triggered by a signup on my landing page.
I couldn't find anything real simple, so I decided to build it. Currently working on it.
Any feedback will be much appreciated.
Since last time, added a "landing-page" kind of website [0], added annotations with BGP events, support for IPv6, and finishing TLS for every communication between probes and central servers.
About to open for beta testers, and still very much interested in comments esp. regarding the UI.
Blog, news, chat, video, mail, web. Basically all the daily habits as little micro apps in one thing. I find it quite useful. Not sure anyone else does yet though.
Also separately worked on Reminder.dev which is a Quran app and API that bakes in LLM based search and motivational reminders.
Been working on this for about 4 years. It has some cool features, like letting you create your own PDF templates with HTML/CSS. Most users love that it's so simple and just a one-time purchase.
Currently thinking about how to implement an Obsidian-style cloud sync feature since that gets requested a lot.
Online part mostly done at https://www.meso.cloud/plants/, currently building glass grow box and light prototypes that will be driven by it.
I’m a Senior Full Stack Engineer with over 8 years of experience building and scaling production systems using Node.js, TypeScript, React, and Python. I’ve worked in remote, product-focused environments where I’ve led architectural improvements, including migrating a monolithic system to microservices, reducing deployment time by around 50% and improving scalability and reliability.
I’m comfortable owning features end-to-end — from system design and API development to deployment, performance optimization, and production support. I’ve also implemented CI/CD pipelines, improved database performance (PostgreSQL), and contributed to cloud-native infrastructure on AWS using Docker and Kubernetes. In addition, I’ve worked on AI-driven workflows and LLM integrations for modern product capabilities.
I’m currently exploring new remote opportunities and would love to connect if you’re building or scaling a product where strong backend architecture, clean execution, and ownership matter.
If it makes sense, I’d be happy to schedule a short conversation. Thank you.

Coding agents are amazing and make me (feel) productive, but they really suck the fun out of programming.
I’m sure it’s possible to create a Godot-based game with an LLM, but I’m not sure how, so I’m forced to do everything the old-fashioned way – reading the docs.
I've been on/off working on a Forth compiler for the NES. It will be open source soon enough but I'm not happy with the code right now as it's extremely messy, repetitive, and buggy, but I think it's turning out ok. I am resisting the urge to use Claude to do all the work for me, since that's depressing.
I've also been working on a clone of the old podcasting website TalkShoe. It's nothing too complicated. It's mostly an excuse to learn a bit more about Asterisk and telephony stuff. I'm hoping to have something fully usable in about a month or two.
I forked the main MiSTer binary due to some disagreements I had with Sorg in how he's running things [1]. My fork was largely done by Codex and Claude, but the tl;dr of it is that it has automatic backup of your saves, tagging and versioning of your saves, and it abuses the hell out of SQLite to give better guarantees of write safety than the vanilla MiSTer binary gives you. I've been using it for a few weeks now and it seems to work fine, and it's neat to be able to tag and version saves.
I think that's mostly it. I'm always hacking on something so there might be a straggler there.

Lots of this is going to involve getting people more up to speed on CS, can't wait.
I'm working on socialproof.dev which automates that step — shareable link, structured form, one-click approve and embed. Wondering if that kind of tool would fit into what a growth agency delivers to clients, or if it's something you'd rather solve with AI prompts and an email sequence.

Heavily using Claude Code to build my own kanban and a Cloudflare native headless CMS meant to feed Astro websites.
I’ve already completed the research, business model, competitive analysis, feature set, branding, and the full UI (40+ screens).
The MVP/V1 is currently in development. When the V1 is ready I’m planning to do a Show HN with this account.
It's my first product. Any feedback or questions are very welcome, even if it's just based on the idea and the screenshots on the site, since the product isn’t available to try yet.
An LLM observability SDK that let's you store pre and post request metadata with every call in as lightweight an SDK as possible.
Stores to S3 in batched JSON files, so can easily plug into existing tooling like DuckDB for analysis.
It's designed to answer questions like; "how do different user tiers of my services rate this two different models and three different systems prompts?". You can capture all the information required to answer this in the SDK and do some queries over the data to get the answers.

This month I'm focusing on long-pending TODO items: self-benchmarking with Terminal bench (https://www.tbench.ai/), fuzzing the security parsers (it executes shell commands, so the threat model is real), normalizing extended thinking traces across providers, and improving the agent UI/UX and TUI components and harness.
Right now we are "OpenRouter for Images", with video following this week.
Our north star is creating a broader developer platform for AI media generation that includes observability, with fine-tuned vision models as a judge to monitor production traffic.
We also have a model arena and showdown page that ranks models by task, so you can find the best model for e.g. photorealism: https://lumenfall.ai/leaderboard
Our stack is Rails for the dashboard and Cloudflare Workers (Typescript / Hono) for the engine.
inspired by the karpathy/twitter posts on running (semi) autonomous research loops, I build https://github.com/tnguyen21/labrat to be able to try and replicate some paper results over night. still early stages but I'm getting some use out of it already.
also spending a lot of time thinking about how you "close the loop" on software projects. right now figuring out how you can combine static analysis + review heuristics to let LLMs course correct the codebase when they over-engineer or produced unwieldy abstractions.
I tried quite a few finance apps over the years, but they all felt too heavy for what I needed. I mainly wanted the fastest possible way to record a transaction before I forget it.
The core interaction is basically:
enter amount → tap category → saved
No save button, no forms, no subscriptions. Just quick manual entry, a simple overview, and a ledger. Data syncs via iCloud so it’s backed up automatically.

I’m curious whether other people also prefer manual entry over bank integrations.
A 2D game programming language with automatic multiplayer. Normally when you make a multiplayer game, you have to constantly think about how every bit of state is going to be synchronized. Easel bakes the multiplayer into the programming language itself, underneath all your code, so you can just code as if all players are in one shared world, like a singleplayer game, and Easel just makes your game multiplayer completely automatically. It’s intended as a fun way for beginners to learn to code - like a combination of Scratch and Roblox.
There are some good tools out there for automating pr review; IMO, they don't catch enough, and they catch it too late.
I've been experimenting with some ideas about a very opinionated AI code reviewer, one that makes an ideal tradeoff between cost and immediacy (eg, how soon after composition does the code get feedback).
Currently in an invite-only alpha, but check out the landing page and lmk if you'd like to be a trial user!
The problem: one buggy integration, scraper, or infinite retry loop can suddenly explode your API costs or overload infrastructure before anyone notices.
Fairvisor acts as a guardrail in front of your API:
per-tenant and per-route rate limits
request budgets and soft/hard caps
anomaly alerts for sudden spikes
The edge component is open source (OpenResty / Nginx + Lua) and the SaaS part provides policy management and audit.
Still early, validating whether teams would use something like this instead of building internal scripts.
There is an API, and it’s a straightforward task, but one thing led to another and I’m also improving the app UI. The update will take some time but I hope it will only be better.

- CO2. Side note: I was surprised to find that most (all?) CO2 sensors used in closed plant production setups are not meant to operate below 400 ppm.
- Air temperature, pressure, relative humidity
- Photosynthetically Active Radiation (PAR)
- Addons like: wind speed, wind direction, soil moisture and Electrical Conductivity (EC)
- The coolest and most challenging: pH, EC, and flow rate
The hardest part has been running everything on battery while maintaining accuracy and using LTE (2–4G) and not common LPWAN options like LoRa. I'm primarily a software guy, so the learning curve has been huge.
When training I like to have every day mapped out with how many miles to run, at what pace, etc as an event in my calendar. My actual workout gets uploaded into Garmin and Strava, but I always wanted it back in the calendar so I could see at a glance the consistency over time. It's been really fun to see other people use and get value out of something I built for myself.
The problem: as multi-agent systems grow, agents need to prove who they are, verify each other, and communicate securely. AIP gives each agent an Ed25519 keypair and a DID, with a trust graph built through vouching (like PGP's web of trust, but for agents).
Current state: 14 registered agents, encrypted messaging, trust scoring, MCP server integration. CLI tool + Python SDK.
pip install aip-identity
I've built it earlier and also did a Show HN, now I am going through some of the steps that get recommended to me such as creating Product Hunt launches, etc. But I am struggling a bit with the concept of PH. What is the audience? People into new apps? It all feels a bit desperate to be honest and this app is just a hobby side project, I am not.
So if anyone knows of a good way to get some attention to my useful fun tool, please let me know.
I'm interested in the idea that LLMs writing raw code and doing line-or-diff replacements will not be the future, but that having the LLMs modify the structure of the code may end up being the best.
Also, I think that building LLM-powered webapps should earn the dev per token call; so I've built a margin into token costs where the end user is charged 2x the provider's token costs, and then I get 20% of the remaining and the dev gets 80%.
I've been working on a solution to automate solar+battery use to arbitrage the market. I'm on a real-time utility plan but even if you're on TOU it can save you $1+ per day by strategically planning when to use the battery and when to conserve or charge the battery. So far it's limited to a few providers and only FranklinWH batteries but I'm eagerly looking for someone to help me get Powerwall support working and other ESS. It's open-source on GitHub as well.
If you operate in the EU and want to avoid heavy fines, this is for you. Once integrated, it allows users to report legal content issues directly to you, which you can then manage via a dedicated dashboard following official EU procedures. Without such a system, users are much more likely to file complaints through official state or EU channels, which can trigger investigations.
Supports only YouTube as the data source, and Gemini 3.1 Flash Lite for processing, but it can easily be tweaked. Runs locally with Docker compose.
An all-in-one tool for structured data extraction with LLMs.
$ struktur extract —input doc.pdf —schema schema.json —model openai/gpt-5
- can prepare documents (PDF->text etc.) - run multiple different extraction strategies - runs a full agent loop for data extraction in-process using Pi agent and just-bash.dev. It can grep through large files for example.
also just posted a Show HN thread: https://news.ycombinator.com/item?id=47310543
I had been doing lots of time-based work for a blog post and ended up annoyed that so many clocks around me were visually out of sync. Especially my microwave and oven clocks. Using the tool I got them synced up beyond what I could perceive.

Parallel agents debate your ideas/work: https://murderboards.ai
^^ solo project / code review agents for non-coders / inspired by Compound Engineering plugin’s code review flow
Now at 350k lines. Native and wasm binaries (you can try the limited wasm version online). Currently adding a full CPython test suite benchmark.
Just for fun, not trying to replace CPython here. Mainly to test the limits of current coding agents.
Think OpenClaw, but durable, with long-term state, and enterprise-ready. We've been using it internally to build agents for a while now and have decided to open-source it.
For those not in in that niche, the goal is to set up a Linux desktop or Steam Deck for retro (and not so retro) video game emulation, so you just drop in your ROMs, open a frontend via Steam, and play your games.
Under the hood it uses a cool legal reasoning agent primarily designed for understanding litigation claims and objectives.
Sometimes I do wish I had a slack channel of like 30 attorneys so I can ask them questions and get feedback.
It also comes with nice features and benchmarking abilities. For running evals, it has a companion called Calibra https://calibra.swival.dev
Version 3 will add more feed types: Podcasts, Mastodon, Twitter/X, Calendar, Reminders, Weather, Finance tickers and more.
It will have a new UI, new features like notifications and local transcripts and summaries and many quality of life improvements.
Build enterprise grade applications (in Elixir) with AI the right way.
Secure. Scalable. Reliable.
Built based on a senior engineer's experience. Uses 10 years of battle-tested patterns, not just LLMs:
1. Uses algorithms over AI whenever possible.
2. No external library dependencies whenever possible.
3. Old school over shiny new toys. Use the right solution for the problem (Eg. SQL vs NoSQL).
Full encryption for notes (uses local encryption before you even sent the note to the server).
I wanted a mixture of Github Gists (sans Git) and 1Password shares so I've been using it eitj great success at my current company to share snippets and private stuff.
Might open source in the future, just need to gauge interest.
I don't think what I am doing is really original, but it's shaping nicely.
I am working on:
- feature folders (one folder per feature, with changelog, issues, summaries etc)
- coworkers (cli-agents, with session management)
- agents intra-response messaging
In general the goal is forcing Claude to behave, which is quite ambitious :).
I'm trying to see how far I can get using AI to help me track pre-owned items for sale, starting with watches. I started with an OpenClaw agent that was looking for specific things I wanted to buy, and then I figured might as well make a whole site for it so I can share with others.

What it does:
Live 10-digit MGRS grid Dead reckoning, two-point resection, pace count, back azimuth Magnetic declination (auto or manual) Waypoint lists with bearing/distance and a wayfinder arrow 6 radio report templates (SALUTE, 9-Line MEDEVAC, SPOT, CASEVAC, ICS 201, CFF) NATO phonetic voice readout NVG-compatible green theme Fully offline — zero tracking, zero network calls, zero data collection. On the App Store. Open source on GitHub.
What surprised me is how little effort this actually took to build. The MGRS math, geodetic calculations, report formats — it's all public domain stuff that's been around for decades. The military is full of overpriced, outdated systems doing things a modern phone handles better. I'm hoping this sparks some genuine innovation, because the people who depend on these tools deserve better than what they're getting.
I'm working on Tech Talks Weekly which is a free weekly email with all the recently published Software Engineering conference talks in the past 7 days.
Every week I pull all the new talk recordings from hundreds of conferences (Devoxx, KubeCon, PyCon, QCon, LeadDev, JSNation, and many more). I feature the ones I think are must-watch with short summaries written by me, then include a list of everything else uploaded that week.
It started as a personal project to fix my own messy YT subscriptions and RSS feeds and now 8,700+ people read it.
I also publish extra editions from time to time like “The Most Watched Talks of 2024” which made it to the HN front page. Currently, I'm working on 2025 edition that will be published very soon.
If you watch software engineering conference talks, you might find it useful.
I’d love to know what you think!
I’m exploring an app idea called Nudge that would gently remind you to check in with specific people if it’s been a while.
I’m trying to validate whether this is a real problem worth building for. Waitlist here: https://forms.gle/pHMABTsbctLXZPZj6
Would you use something like this, or do existing tools already solve it well?
- Portable Secret (https://alcazarsec.github.io/portable-secret/) - self-contained HTML files that decrypt in the browser.
- Dead Man's Switch (https://alcazarsec.com/deadmanswitch) - sends messages when you stop checking in.
- Flare (https://alcazarsec.com/) - silent alert when your device is accessed without authorization.
I also agree that you should be able to make a DAGR 2 that is much smaller and more powerful but it would always have to be a standalone device.
That said, the vast majority of DAGR usage I see isn't in GPS-denied or spoofed environments — it's in land nav training, patrol planning, calling in grids on routine ops, and reporting. For those use cases, a phone with good civilian GPS (3-5m accuracy now with dual-frequency) handles it fine.
I'd love to see a DAGR 2 that's smaller and cheaper while keeping SAASM though...here's to hoping we get more options
I ask because I was recently thinking about how to preserve information for the future like this
This seems unlikely, however, since our infrastructure costs for the dead man's switch are covered by just a handful of subscriptions. Besides, we host it next to our other more profitable main product, so it gets free maintenance.
We are up for the challenge of making this last for many decades, though. It is a beautiful mission.
I have found out that it is very efficient to use phaser.js/three.js for fast, vibe coding, because it handles everything without having to setup a unity scene manually or unreal blueprint. I really recommend to make web apps instead for vibe coding. I love how easy it goes.
Big props on the no install / no register etc philosophy. If i would had to make any account i probably would have closed it instantly again xD
So the first thing i STRONGLY recommend, add somewhere a help text (before starting game or small on the side of ingame and ability to disable via options) for the controles.
Im on a Desktop, i started the game and i expected some sort of short info about controles. Yes theres a tutorial - no i didnt play it. I mean lets be honest... tryNSucceed :D
So ye i spend the first 2-3 Stages only spamming spacebar because it didnt came to my mind that maybe its with mouse support (visually it really hard compares to vs-likes that dont support mouse).
So i can tell - ice mage with just massive rapid space spamming works perfectly fine through the whole earth stage. ^^
I find the base look finem the overview texts for the different arch types is well done (even tho it confused me that fire and ice dont have weaknesses?).
The point that at least for me was the most well, unpleasent? , is the size of the play area. I guess you made this to fit easy with smartphone screens, but on a desktop its like not even 1/4 of my screen (and im not on 4k or something) so dunno it feels just alot to small. May fit for a smartphone but for a desktop its just very very limiting while the game takes alot of space for basically nothing.
Also, you definatly should have a "Settings" button in the game pause menu which allows for changing sound levels. Not just a "total sound" bar but at least have Music and Sounds (attack etc) seperated. Because, frankly speaking, the music while for the first like 30 seconds is cool, very fast is dunno it just would fit more to the entry video scene of something than as a constant thing (my pov) - so i wish i would be able to just disable the music and still have the attack/battle sounds. Adjusting both tho would be great anyway and i think with phaser should be quite doable.
A smaller point (visual) is the size of the health/mana bars. Even tho i know they are in the top left, i kinda have to squeece my eyes sometimes to see them. So i would probably just make them bigger.
That all said, i mean i just played solo till the fire stage :) and i clearly had a bit of fun.
I would say its a great start and if you go on and refine it i see a chance that people might pick it up as a nobrainer lets just game something solution :)
Best of luck !
The problem it's solving is one most people building with LLMs know well. Your prompt fails on some inputs, you don't really know why, and you end up just tweaking and re-running until something sticks. We kept hitting this ourselves and it felt like there had to be a better way than guessing.
What we figured out after a lot of research: prompt failures almost always follow a pattern. The model isn't failing randomly, it's consistently failing on a particular type of input or reasoning step. VizPy finds that pattern, distills it into a plain English rule you can actually read, and then rewrites your prompt around it. You also get the rule itself so you can review it, tweak it, or just drop it into your existing prompt directly. DSPy-compatible, no pipeline rewrite needed.
We have compared it extensively against baselines such as GEPA on benchmarks like BBH, HotPotQA, GPQA Diamond, and GDPR-Bench and VizPy wins on all of them. We'll have more benchmarks on cyber-security and chip-design coming out soon.

- golang based architecture
- information is dynamically mapped into one central directed knowledge graph
- default multithreading
- utilizes existing tools (such as nmap/nuclei/katana/wfuzz/....) instead of reinventing the wheel
- architecture is (tldr) a self supervising logic in which every worker is also a scheduler that based on delta causality uses cartesian fanout and graph overlay mapping including local only witness nodes to dispatch new "jobs" without having a central scheduler or the necessity to scan a central total job queue to prevent duplicate executions.
In this architecture every "action" that can be executed defines an input structure necessary. If the previously mentioned mechanic identifies a possible job execution it will create a job input payload which will automatically be picked up by a worker an executed. Therefor every action is a self containing logic. This results in a organically growing knowledge graph without defining a full execution flow. It is very easy to extend.
I worked on this for the past ~10 years (private time). The sad truth tho is, while this project was initially planned to be open sourced - after i not to long ago for quite some bucks consulted a lawyer, i basically was presented with the fact that if i would publish it i could get sued due to germany's hacker and software reliability laws. So for now its only trapped on my disk and maybe will never see daylight.
Im right now working on a blog article (thats why i even mention it) about the whole thing with quite more detailed description and will also contain some example visual data. Maybe will post it on hackernews will see.
PS:The tool does not need llm/nn.
About an hour ago I was dismissed as AI slop on the r/rust Reddit. Whatever.
This tool is my line of defense in case `trunk` goes dead, which it seems to be increasingly likely. It helps me build fullstack sites using Actix Web and Yew.
Using it now to see if I can re-invent my blog site for the umpteenth time. :)
Published a demo/experiment under MalleableTodo [1] - and so far seen some pretty strange use cases...
Essentially, just allows each user to use an LLM to rewrite their own UI to add features/customisation.
A browsable map of internet infrastructure. Not just a collection of lookup tools, but it also interlinks results, so you can navigate linked assets as well. Think: DNS lookup -> SPF record -> mail provider's SPF record -> IP address details.
i don't have much free time, but it's important to me to have healthy side projects, so here's what i'm working on:
- rsyncthing: A command-line CLI that lets users quickly bootstrap Syncthing fileshares to new hosts over SSH. No more "introduce devices to each other" song-and-dance.
- stringlines: i'm working on a small app for my own personal use that will help me plan transit in the NYC area better. A lot of map apps (Apple, Google, Transit, Citymapper) don't show recently-departed trips, making them much less useful for judging the feasibility of tight connections on the NJTransit rail lines. So I'm building out some infrastructure to record the GTFS-RT feeds and display them in a mobile-friendly format.
- slowly playing through all 70 the quake brutalist jam III maps to learn more about level design.
Most of these side projects are claude-free for now, mostly because I want to build domain expertise for myself before involving the agent tooling.
I run it at https://ferdig.de
It started as a client problem, then something which I also experienced so decided to built it. It's just one small script and work seamlessly across platforms.
So FormBeep is designed to work with WhatsApp since most people prefer whatsapp notifications!
A free tower defense game - https://vectordefensegame.com/game
A free Xpilot-adjacent game - https://vectordefensegame.com/yeetpilot/lobby
This is the type of project that I never would have started in the first place if not for LLMs.
- look for feedback on the Freelance Rates calculator https://heygopher.ai/tools/freelance-rate-calculator
One thing I've noticed building in this space: freelancers are remarkably bad at collecting testimonials from clients (who usually love them!). The workflow ends after the invoice is paid and nobody ever goes back to ask for a written review. Worth thinking about whether that's a hook you could add — "invoice sent, client paid → automated ask for a testimonial."
I'm building something adjacent to that problem: socialproof.dev. Would be curious what your users say when you ask how they handle testimonials.
Agents can search for design inspiration from production websites using semantic search. Since this inspiration comes from live websites, their design tokens; colors, typography usage, layout data are also available.

A few years ago it started as colorguesser.com - which is not much maintained, but since there are many new users enjoying this small game, I decide to invest more time and add more feature.
Mission: get startups access to senior & principal big-tech engineers at a 90% discount and without hemorrhaging equity.
The hack is that I'm tapping into a hidden supply of people hiding in plain sight: top engineers that are already full-time employed in big-tech with benefits who enjoy helping smaller startups, and, recently retired people who want something to do.
The name I'm using is Low Touch Advisor because we are selling what I call "low touch" help in the form of async Slack based guidance. By having access to senior people perfectly matched to your team's needs, you can use your actual engineers to do the hands on and majorly reduce the likelihood that a major rewrite is needed after 6 months of effort on new projects.
Basic model: - Our customer (an early stage company) pays $1,500 / month with no long term commitments to get async Slack help from a vetted senior/principal engineer perfectly matched to their needs - Of that, we ACH $1k / month to the engineer who provided the Slack-based help
Within the first 3 months of operating, I have $27k of monthly revenue booked in my sales pipeline.
So far I've done everything by hand but once I'm a bit further ahead, I'm going to look to begin automating this.

I got it all done in probably an hour or two. But done in 10-15 min blocks over many days.
Platform for running web apps.
Single static binary and SQLite
lua for now (WASM future)
DEMO:
Group chat photobooks. Automatic layouts, no editor/app, unlimited free previews. Build a hardcover (up to 1000 image) and ship it in minutes.
Wanted a physical souvenir for everyone in my long running signal chat but didn’t want to spend hours curating in editors.
I'm enjoying building solitaire and puzzle games.
My goal is to make this project the largest online collection of free modern solitaire games available for all kinds of devices.
Example: Slack: https://bloomberry.com/data/slack/
Not templates with names swapped in. Every story and illustration is made from scratch. You can go from "dinosaurs soccer" or write out a whole storyline. Pick an art style, optionally upload reference photos of your kid, and it builds a 28 page book in a few minutes.
Bilingual in 38 languages. We handle RTL (Arabic, Hebrew), CJK, and less common languages like Estonian, Maltese, Irish where there's not much available for kids.
Tech side for the curious: LangGraph orchestrates the pipeline, Celery workers do image generation and text rendering in parallel, and LLMs critique the illustrations for consistency mistakes and can trigger regenerations automatically.
Printed in Germany, booklet around 20 EUR, hardcover around 40 EUR.
My first agentic app to dive head first into the AI world not to be left behind, oh boy this new world moves faster than I thought.
Feedback highly appreciated
My kid played it, and didn't stop for 45 minutes so I think that's a win :-)
- Visual cards with titles and thumbnails
- Playlists keep research focused
- One private URL for editing, share links for viewing
- Fast import for friends and teams
Any feedback is welcome :)
Environment variable checker - pretty niche.
What would make you use this? does this miss anything useful?
However, none of the clients want to follow the development rules that I have built up, so I am trying to build my own.
The main thing I'm currently working on is a platform for organizing and discovering in-person events. Still not certain about the boundaries for "Phase 1", but I have a bunch of ideas in that space that I've been incubating for a while. One subset of features will be roughly similar to that app you've probably heard of that starts with 'M' and ends with 'p', but hopefully an improvement, at least for the right audience. But wait, there's more. :)
Currently building it; it's not public yet, so no link. Next month.
Thinking about how to grow the userbase is intimidating, but I think it might end up being fun.
Most productivity apps make you do the organizing — projects, tags, priorities, fields. That's fine when you're calm. It's impossible when you're overwhelmed.
I'm building for the moment when your brain is full and you just need to dump everything out. You throw in voice, text, images, links — Ordr calls an LLM to parse intent, extract tasks vs. events, assign order, and surface one clear next action. No tagging, no sorting, no deciding. Just: here's what to do next.
Built with Flutter + Supabase + Groq/Cerebras. Still early.
Curious if anyone here has hit this wall — tried every app, built their own system, still feels broken. What did you actually need that nothing gave you?
It sits on top of what I already use and gives me a unified "What do I need to do (now/today)?" view.
Trying to auto-capture action items from meeting transcriptions and other inbound, and routing quick thoughts to the right tool with a couple of keystrokes, helping me prioritise my day so I'm not spending energy on too much organising (or through lack of organising getting distracted).
I wanted something that watched my inputs and keep my GTD loop running, especially when back-to-back meetings and context-switching make it really hard (or impossible) to stay on top of things I need to do!
Might also augment it with LLM for some support of task breakdown, but only as human-in-loop assistance.
Not thinking this could ever turn into a product since it's so custom.
RClone is doing the heavy lifting of reliable & fast cloud to cloud transfer. I'm wrapping it with the operational features clients have asked me for over the years:
- Team workspaces with role-based access control & complete audit log of all activity
- Notifications – alerts on transfer failure or resource changes via Slack, Teams, json webhook, etc.
- Centralized log storage/archiving
- Bring your Own Vault integrations – connect 1Password, Doppler, or Infisical for zero-knowledge credential handling
- 10 Gbps connected infrastructure for handling large transfersThe interesting engineering problem was ChEMBL: most phytochemical names don't have direct ChEMBL entries, so the pipeline first tries a name match, then falls back to PubChem for CID → InChIKey resolution before hitting ChEMBL's molecule API. Full enrichment with Aho-Corasick string matching took ~24 seconds for 24,771 compounds.
Building the commercial layer on top: Rust/Actix-Web API, 97K static pSEO pages on Cloudflare Workers/R2, Stripe for one-time purchases. Solo founder, bootstrapped, based in Germany.
We use landing.ai to parse the PDF, as well as useworkflow.dev to durably perform other work such as rendering PDF pages for citations, and coordinating a few lightweight agents and deterministic checks that flag for inconsistencies, rule violations, bias, verify appraiser credentials, etc. etc. Everything is grounded in the input document so it makes it pretty fast and easy. We’re going to market soon and have an approval sign up gate currently. Plenty of new features and more rigorous checks planned to bring us to and exceed parity with competition and human reviewers.
There’s plenty of margin for cost and latency versus manual human review, which takes an hour or more and costs $100 or more.

Also wrote a small clone in Rust, just to try the language: https://github.com/epogrebnyak/justpath.rs
So far Python is easier for me, but I transferred some code organisation ideas from Rust to Python.
Extra benefit of Rust is that you can get a runnable binary, in Python, well there is a lot you are installing even for a simple utility.
Someone made a PR on brew installer for the Python utility, but it seems fully claude code and I'm not sure it is the best way to package brew.

Today I released the community plugins for Voiden.
This is a big one because one of the things I dont want is the API tool to become bloated with new features - so I want to allow anyone to build plugins to grow the tool.
Its been pretty fun cosplaying as an network engineer, and now I'm building out an Anycast network for a few ideas that I'm working on.
Its nothing too revolutionary or new, but I'm proud that I've built them from ground up and all running on my own infrastructure.
- DNS Authoritative Hosting - https://thelittlehost.com/dns/ - Quietnet - A family-focused internet filter - https://quietnet.app
I'm also getting ready to launch https://relaye.io, which was my personal tool I built to support my devops consultancy.
Because source isn’t always available, it scans the bytecode of an application and the new library, building a full graph of each component in Neo4j to determine what breaking changes impact the target application. This is then translated into tickets and prompts to drive an LLM to make the appropriate changes.
Handling library upgrades is rarely interesting and just adds to our overall technical debt, so it has been nice to automate it away so that we can focus on features and functionality. It supports Java and .Net currently and we’re actively adding support for other languages.
- 2FA, PassKey, and password-based login for folks that hate magic links
- Moved my entire API from GraphQL to REST so I can fully dogfood the API I offer
- Added an audit log as standard on all plans
- Built a terraform provider (https://github.com/OnlineOrNot/terraform-provider-onlineorno...), and a way to download existing config into terraform files
- Started iterating on a CLI (https://github.com/OnlineOrNot/onlineornot)
Email averages ~20% open rates on a good day. A postcard sitting on someone's kitchen counter for two weeks is hard to compete with. I've been building out the programmatic side. API, Zapier, and native integrations with Jobber and Zoho so you can trigger physical mail from the same workflows you already use for email.
Shopify integration is almost out the door too, which opens up a lot of interesting abandoned cart and win-back use cases for stores whose customers have opted out of email.
No bulk minimums, no design software needed. If anyone here wants to give it a try, reply or email me and I'll set you up with some free credits to get started.
For this iteration of the project, I'm using Manus to build it. My first stab at using AI to build a web application, and the results have been interesting. Although I'm not debugging the code as much with this approach, I was surprised to still feel a similar level of 'fatigue' as I'm guiding the LLM along with the build. Check it out, would love your thoughts!
I’m working on CodeYam. We just recently released a lightweight CLI and a feature called CodeYam Memory. The immediate motivation was that when using Claude Code, the AI would repeat the same mistakes and our claude.md files would get stale too quickly to manually maintain. The existing options, including Anthropic’s built-in memory features, didn’t really solve the memory challenge sufficiently for us.
CodeYam Memory runs a background agent that reviews coding session transcripts, looks for patterns of confusion, and generates targeted rules with proper scoping.
It’s a small first step toward the longer-term idea I'm exploring: what an AI-native development experience should actually look like. For now, it’s packaged as a lightweight CLI you can use anywhere you’re running Claude Code.
How to try it:
Install: npm install -g @codeyam/codeyam-cli@latest
Then, from your project root run: codeyam
This will launch a dashboard with further instructions for initializing CodeYam Memory.
Free, runs locally, no login required, and language agnostic. Would love feedback.

I've been planning a new idea with that and possibly future ideas based on the future (and near future) where there are more and more "agent" users.
Link to website:
Aside from that, I need to document and properly release one of the pieces that PAPER is relying on (some generic tree-processing code that makes operations on directory trees a lot nicer than with the standard library "walk"s), and work on others (in particular, a "bytecode archive" format for Python that speeds up imports for some projects, mainly by avoiding filesystem work at import time — I want to offer it as an install-time option in PAPER, and later have `bbbb` make wheels with the bytecode precompiled that way).
Physical engineering is a huge welcome transition for me from what coding has become in the last couple years.
There’s something nice about the realities of creating a model, then printing it, then seeing that exact is too exact, then reprinting, then eight more times, and then that feeling when it all comes together properly.
A few weeks ago I was working on an adapter for an airbrush to use on a standard pancake air compressor. Learning to create threads in blender was really neat! I learned a lot about the physical construction of threads, something I have never put much thought into before.
Phase 1: Download the student's code from their submitted github repo URL and run a series of extractions defined as skills. Did they include a README.md? What few-shot examples they provided in their prompt? Save all of it to a JSON blob.
Phase 2: Generate a series of probe queries for their agent based on it's system prompt and run the agent locally testing it with the probes. Save the queries and results to the JSON blob.
Phase 3: For anything subjective, surface the extraction/results to the grader (TA), ask them to grade them 1-5.
The final rubric is 50% objective and 50% subjective but it's all driven by the agent.

It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.

The problem I kept seeing: freelancers have happy clients but almost no testimonials on their site. Asking is awkward, clients say "sure!" and then never write anything.
SocialProof gives you one shareable link. Client clicks it, fills a short form (name, text, optional photo), you approve it, it embeds anywhere. No login required for the client.
The interesting technical bit: it's entirely on Cloudflare Workers + D1 + Pages. The collection form and embed widget are edge-served globally with no origin server. Been curious whether anyone else is building purely on Cloudflare's stack and what they've run into.
Still pre-revenue (just launched today). If you're a freelancer or run a small agency and have thoughts on how you currently handle testimonials, I'd genuinely love to hear it.
I was spending way too much time staring at logs and web dashboards trying to figure out why my multi-agent setups kept failing.
You just point it at your traces (LangSmith, Langfuse, OpenTelemetry, or a JSON file). It pulls the system prompts directly from the logs, extracts the behavioral rules, and uses an LLM-as-a-judge to replay each conversation step-by-step.
It flags exactly which turn broke things, which agent caused it, and traces cascading failures across routing, handoffs, and retrieval.
It aggregates root causes across all of them: "24 out of 51 failures are missing escalations." You know exactly what to fix first.
Runs locally. Only LLM API calls leave your machine. You can try it without installing anything.
- Urbanism Now - I run https://urbanismnow.com, a weekly newsletter highlighting positive urbanism stories from around the world. It’s been exciting to see it grow and build an audience. I'm thinking of adding a jobs board soon that'll be built in astro.
- Open Library - I’ve been helping the Internet Archive migrate Open Library from web.py to FastAPI, improving performance and making the codebase easier for new contributors to work with.
- Publishing project - I’m also working on a book with Lab of Thought as the publisher, which has been a great opportunity to spend more time working with Typst.
These projects sit at the intersection of technology, cities, and knowledge sharing, exactly where I’m hoping to focus more of my time going forward.
Downloaded and parsed a bunch of the pgsql-hackers mailing list. Right now it’s just a pretty basic alternative display, but I have some ideas I want to explore around hybrid search and a few other things. The official site for the mailing list has a pretty clean thread display but the search features are basic so I’m trying to see how I can improve on that.
The repo is public too: https://github.com/jbonatakis/pginbox
I’ve mostly built it using blackbird [1] which I also built. It’s pretty neat having a tool you built build you something else.

* Telephone handset for my mobile phone with side talk.
* First draft of a book / workbook on Work Flow. Outcrop of the work flow consulting I do, stuff I've learned, and so on.
* Short film script - trying to convince a local actor to play the lead before we lose the rainy season here - otherwise we'll need special effects or just wait until the fall.
* Polishing firmware, OSX, and iOS suite for a wearable neuromodulator unit. Deadline in a week!
* Nmemonic community and app - been poking at this for years and finally had a breakthrough on the UI. My first app to release in the wild, so pretty exciting.
https://github.com/RedbackThomson/nix-tasks
I started this project because at my company, we're still relying on ancient Makefiles as our build system and build tool versioning. I initially looked at using other task runners but they all use some sort of DSL that I think limits their functionality and/or doesn't allow for sharing and extending templates across repos. Nix-tasks lets you use Nix flakes to share common configuration - like your company-wide build scripts - and then import it and add repo specific tasks on top of them.
The project is still very much in alpha but I am using it every day and trying to find any annoyances or bugs before I share it further.

Currently dogfooding and evaluating whether it helps in the long term or not.
So you can use it to write UIs in web and use them either as regular Qt widgets or as stand-alone webapps with regular node backend.
It's really the wrong way around if you think about it.. using an inferior technology (web) for the UI part.. But somehow people prefer typing CSS and downloading gigabytes of boilerplate instead of just using a WYSIWYG designer.. I don't get that part..
I've also used tweakcc to make this work in Calude Code and plan to also do one for open source coding agents - codex, pi, Gemini, etc. And I'm also doing Livestreams of the development process.
Just launched on the Mac App Store last week, now figuring out the discovery side which is the hard part. Turns out that doing the best App doesn't mean much if no one knows it exists!
Also moving to Sveltia as my CMS (Astro markdown blog), after exploring multiple other options. Changed the structure of my Obsidian vault, will write about that also.
I’m also still working on a few projects:

I'm also using this as an experiment to see how to use AI tools to build a maintainable project of medium complexity. Too big to do in "one shot", but doable if decomposed into a few dozen tasks.
It's going well! I think I only started Saturday morning and put in maybe 4-5 hours on it, and it's in pretty decent shape. Not ready for prime time yet, but only a few hours away from replacing Cal.com for my own use. The slowest part is that I'm manually reviewing the code, but that's part of the deal for this experiment.
The paper in question: https://arxiv.org/abs/2602.05274 (published in the Journal of Mathematical Biology)
Lately been deep in PDF/X print production - PDF/X-1a and PDF/X-4 with ICC color profiles and CMYK conversion. Had to build 11 color space converters on top of PDFBox 3.0. Also shipped an AI template generator where you describe what you need and it creates a Handlebars template with sample data, plus expanded the gallery to 38 pre-built ones.
Right now template management lives in the dashboard - edits auto-create drafts, you can compare any two versions as rendered PDFs and roll back if something breaks. Working on an API so coding agents can create and version templates programmatically.
I have too many project cars and bikes, I wanted one place to store vin numbers for searching parts, and then just kept adding useful features.
Supports 16 vehicle types (cars, trucks, motorcycles, boats, tractors, ATVs, RVs, etc.), not just cars. Also includes maintenance tracking, a browser extension that auto-fills your vehicle info on parts sites like RockAuto and AutoZone, a community-vouched trusted shops map, and a vehicle selling wizard with state-specific bill of sale generation.
Free tier gives you 1 vehicle with a full diagnostic.
After adding a couple of extra features and having a "finished" tracker, I will try re-implementing this tracker in React, Svelte, Vue, Preact and some others.
My goal for this project is twofold: to get familiar with these frameworks and to practice using AI as a personal tutor (leading my way and answering my questions).
I've tried learning React, Laravel, etc before, but I've used them to build a fresh project from scratch and I've always got stuck early on due to the lack of knowledge/understanding.
I hope that re-implementing something that I already know and understand fairly well would make my learning process much more effective.
Since then, I configured all the hardware (switches, router, server, bastion host, etc), put it in a real colo, and am doing BGP with one upstream (with a second upstream and some peers on the way). This means I'm officially part of the internet! E.g. https://bgp.tools/as/55078
I'm just working on some BGP and network hardening stuff, then I'll start putting real live services on the server. And in parallel, I'm working on getting the link from my home to the colo active, so I can be my own home internet provider.

It has a few core libraries built in rust with a web app and a terminal UI. Android app is in the works. The persistence layer is intended to be offline first using a CRDT with an optional sync server. I'm also trying to integrate "bring your own AI" assistants to help tweak recipes or make suggestions.
It's been a fun way to sharpen my claude skills but also to see how feasible it is to maintain multiple frontend applications with a large amount of shared code. Still a lot to do, particularly the core calculations are not yet on par with existing offerings.
Applications on the public cloud raise strong concerns about data protection. As an architect, I spend a meaningful part of my time ensuring the security of customers’ data in the cloud.
Bao introduces an innovative approach where data remains on local devices while the cloud provides encrypted storage for synchronization and peer exchange. Because cloud providers cannot access the data, the need for due diligence is reduced.
Any feedback is welcome.
The goal is to get consistent synthesis to 450MHz such that I can use a narrower 256-bit instead of a 512-bit interface, while maintaining full bandwidth. I've got it working at an FMax ranging 440-490MHz, though there's still some edge cases I need to hammer out.
It’s been available as a free tool for years, growing to over 45k active installs. I just rolled out the Pro extension to offer more advanced features, and the early traction has exceeded my expectations. If you're running e-commerce in Europe, this is a must-have for staying compliant with EU law.
Originally I made it for my grandpa, but I got a lot of interest so I made it into a full commercial product.
Just yesterday I published a set of 3 mini tutorials if you want to see how it works - https://youtube.com/playlist?list=PLKt1F5TvOjAHE07oBDlPXcrHc...
Very early days but will keep updating them & adding more.
Also working on https://www.kinoko.sh/. An agentic engineering platform built from the ground up for agents. Custom language and architecture and a layer of formal verification on top. Also working on a custom inference engine that produces well typed programs
I'm not sure I'll be putting it out there because it feels like there's already 100s of these apps out there so I don't feel strongly about it.
It turns your Google Sheet into a live API.
We know the "Sheet to API" space is a little crowded, but we've always wanted to get better at distribution, marketing, and growth hacking. We needed a real product as a sandbox to learn, so we built a tool that we'd use ourselves.
There's a free tier. I'd love to hear any feedback on the product (or our marketing efforts!). Thank you!
Now I've written quite a few posts (and given talks), I thought of writing a book. Just wrote two chapters. The draft lives here: https://www.jjude.com/books/hs/
Oracle's plugin allows you access Fusion REST Endpoints (your business data) from within an Excel workbook but it only works on Windows machines and has some other limitations.
Also added a plugin for inspecting punchout payloads for RSSP [2]
So I build these two app to create items and spell cards and print them out.
The workflow: Upload doc → LLM extracts structured data → Generate new doc from template.
It’s API-first, includes webhooks, and is built to be self-hosted/self-provisioned for privacy. Still very much a WIP, but looking for feedback on the feature set and the extraction accuracy.
URL: https://fetchtext.io
It’s been a great way for me to better understand the cloud GPU industry, learn about data collection, normalization and use agentic coding to build a side project.
One thing I’m working on is distinguishing spot vs on demand prices and listing those separately. Also, including inference pricing for non-text AI models.
What features or data would you like to see me add next?
- http://sharpee.net : Text Adventure authoring platform in Typescript
- https://github.com/ChicagoDave/tsf : A multi-target npm build tool
- https://devarch.ai : Claude Code guardrail workflow including hooks, agents, and skills
In progress:
- unnamed project to disrupt commercial site hosting including a new marketplace
It may be that my target audience is already building their own “devarch” but I still have to validate the ddd parts and that will be a differentiator.
My sales are likely going to be corporate via consulting connections.
There’s a ton of prompts I never bother with anymore because DevArch does things for me.

Export your Apple Health data directly to Markdown files in your iOS file system.
Open-sourced it at https://github.com/CodyBontecou/health-md.
Fun little vibe-coded app that has made a lot of users happy.
So far, I think it is in fact worth it, but only in specific use cases, like very rarely accessed items with no obvious place, and making sure your AV gear you bring to events comes back with you.
* Every item is a container, unlimited nesting
* Everything stored in the browser with YJS, very clunky peer.js or manual file sync available
* Select an object, click add items, scan QR codes to add those items
* There's also NFC support on Chrome mobile
* Generate random printable QR sheets(Still need to fix sticker alignment issues)
* Tracks where an item was last scanned with GPS
* Save container contents as a loadout, check contents against loadout
* Can mark a container as needing re-inventory, contents that haven't been re-added after that show a warning
Put One In for Johnny Minn (https://store.steampowered.com/app/3802120/Put_One_In_for_Jo...) - A small soccer game all about scoring nice goals. While I don’t expect it to do well, I’m very happy with how it came out, and it’s the first game I’ve made that I’ll release on Steam! Comes out on Thursday (March 12th).
HeartRoutine (https://www.heartroutine.com/) - I built this a few months ago to help me stay on top of my heart health. I enter my numbers on the (offline) app, and then configure my goals (like “lower Apo B through diet and exercise”), and then the server emails me every morning asking me what I ate yesterday, how I exercised, etc. The goal is to stay on track, and to be able to bring a cardiologist a very detailed report.
All data lives in your browser (IndexDB) - https://buyitlater.vercel.app
To me good is - Pre-determined lists of words - Audio examples - Sentence examples - Native app with offline support
most importantly: - No business model that requires a subscription
I'm trying to see it more as writing a text-book, than starting a business
I started it after an AI coding agent destroyed my SQLite database mid-session for the third time. Git doesn't back up databases, and it shouldn't. But nothing else was doing it either.
It runs silently in the background and watches your project, detects changes, backs up to encrypted cloud storage (Dropbox, Google Drive, OneDrive, iCloud). Supports SQLite, PostgreSQL, MySQL, MongoDB. Has a native macOS menu bar dashboard.
Free and open source. v2.7.0

I first used DynamoDB 8 years ago and have been designing single-table schemas heavily since. For me, the best way to create drafts was always pen and paper (and then excel/confluence tables), but in reality it's a process (based on The DynamoDB Book) that can be automated to an extent.
Decided to build an app while on paternity leave. You define entities and access patterns, create (or get suggested) key and GSI design, and generate code for access patterns (TypeScript and Python), infrastructure (CDK, CloudFormation, Terraform), and documentation you can share with stakeholders.
There's more I want to build beyond the MVP - things around understanding and validating designs that you can't get from a chatbot - but for now focusing on the core.
If anyone wants to try it out, sign up for the waitlist on the landing page. MVP should be ready in the next few weeks.
The core pipeline: AI generates structured quote pages → automated image synthesis with custom JSON templates (typography, gradients, layout) → Pinterest distribution for social traffic alongside Google SEO.
Currently in English traffic validation phase. Interesting challenge has been tuning the image generation — switching from monospace to serif fonts made a surprisingly big visual difference. Also figuring out the right balance between AI-generated content volume and quality signals Google actually cares about.
Next steps: Spanish/Portuguese expansion, then launching inspirationalquotes.app as a paid AI quote image tool for social media managers and HR teams.
Happy to discuss AI content site architecture or Pinterest SEO if anyone's been down this road. https://motivational-quotes.net
We recently added an AI integration, starting with a UI agent. We're experimenting with a BYOK approach so anyone can try the assistant in the playground[1] without signing in while keeping it sustainable for us. Currently the AI integration connect to Gemini.
A logic agent is in progress, it's a bit trickier because it needs to work with Breadboard's visual-stacked-instructions language based on Hyperscript.
We're also releasing documentation.
[1] https://app.breadboards.io/playgrounds/hello – to access the AI assistant click on the Duck on the dock, you can try with a free api key from Google AI Studio[2] –
The basic idea is daters "teach" an algorithm what they like and then the algorithm uses the collective set of preferences to match everybody (or as many as possible) for single in-app "get to know you" chats. Everything is one-on-one to avoid overload and dead-end chats.
I now have working versions in the app stores and I'm currently testing in Seattle.

a) how are you going to do the marketing?
b) according to my experience, all this social/viral stuff etc. does not work anymore today
c) former ideas like content & SEO -> is dead
d) nobody wants to talk today about anymore on being on a dating app?
e) And Sorry for being an Ass here: After I've lost a not-that-low-number of funds due to "following this idea" (just for prototyping/alpha & beta & final release), my recommendation is: Stop this immediately, it will save you years of your life! Im absolutely pro creating whatever app or service you may come along, but please please forget the dating market
P.S.: you will come back to this comment in 4 -5 years, latest :-)
You’re right that the 'traditional' playbook (SEO, viral loops) is largely broken for new dating entrants. Largely because I believe there's a lot of dissatisfaction with current offerings, I've been able to build a decent sized list of folks who want to try it out.
I'm curious. Given your experience, do you think there's any room left for hyper-local, community-first growth, or is the market truly locked by the incumbents regardless of the tech?
I’d love to hear more about where you saw the biggest friction points during your release.
For those interested in the fellowship - https://www.cai-research-fellowship.com
The platform my research partner and I have been working on is called Habermolt (https://habermolt.com).
The idea is to create an open-source platform where you teach an AI agent your views (basically just populate a user.md) and send it to deliberate with other people's agents. A consensus statement comes out the other side.
It builds on the Habermas Machine (published in Science, 2024, Google DeepMind / MIT). We're two researchers trying to turn that into something anyone can use.
The overarching motivation for this project/ the thing we're trying to solve for is that representative democracy scales but doesn't listen, and deliberative democracy listens but doesn't scale. AI agents representing you might be the first mechanism that does both.
We have about 50 users and 52 live deliberations. One example: agents debated whether employees should own their AI agents and landed on "Personal Agent Portable, Company Data Stays" - your agent shaped by your knowledge and skills is yours, company data stays with the company. Nobody moderated that. Four agents just argued it out async.
The honest challenge: people love the concept, try it once, and don't come back. We're trying to figure out what turns a curious visitor into someone who actually uses this. Would love any thoughts on that.

I wanted a way for my kid to learn the alphabet, but without a UI that looks & behaves like a slot machine. It's all maximally slow, relaxed and designed to be easy to put down.
The idea came from trying to find a neat screenshot app on Linux for taking and sharing screenshots for another SaaS I'm working on: LanguagePuppy [2], but I couldn't find one that worked. So I rolled up my sleeves and started to make my own using Clojure.
The main features are: 1. Taking screenshots 2. Adding padding, shadow, and rounded corners to the screenshot 3. Adding background 4. Choosing the right ratio for your target social media 5. Adding watermark 6. And more
Eventually, it should work on Linux, Windows, and macOS when I launch.
P.S. I am building both with Clojure, a functional programming language, and Lisp.
* https://sprout.vision/ - AI generated Go-To-Market Strategy for launching your next venture. I have a Tech background with limited GTM experience, so I experimented with AI to learn about different strategies and decided to turn it into a simple product that will generate a comprehensive plan (500+ pages) to help you launch your next venture. Try it out, would love to hear your feedback, use the HN50 promo code for 50% off your order.
* https://pubdb.com/ - Reviving a 10 year old project, it’s meant to make research publications more accessible to mere mortals with the help of AI.

Coffee Roaster Aggregation ETL using fastapi, nextjs, bs4 etc etc. It's been fun, just finished up the oauth for discord that pairs nicely with the info required to make Discord dm notifications function. attempting to charge 6$ for the instant notifications, but doubt many people will be interested. up to 75 roasters and all of them are checked every 10 mins for new products.
Considering reusing the repo as a framework for other industries if this project ever gains any traction. Also was considering adding a goofy rag discord bot to the server just because i love tossing in a rag layer everywhere lately, and feel like i fall a bit short on my filters for stuff like origin/flavor notes and all that junk. Semantic search with solid chunk strategies might create a better solution than if i did get all the filters working as well as possible.
This has been my side project for nearly a year, and I also shared it here in HN when it was in alpha [2] and received a ton of feedback (and stars on GitHub).
The project has evolved quite a bit since then, like having additional file format support, lyrics, Last.fm scrobbling, and more!
It's heavily supported by Claude Code, but much fun.
Actually not built on this yet I think, but I could switch over, haven't made anything more of it since it's still a bit rough around the edges, and I keep finding various issues during actual usage: https://binschema.net/
there's no control plane, each node is equal and eventually consistant and its (so far) end to end rust so a very minimal footprint per node.

Written in Zig, it has a C FFI and a CLI for mac/windows/linux.
The purpose of this is to feed into a different project I'm working on that is for-pay.
It's MIT open source, offline first, single binary
I put together a pretty basic portal clone. I think its pretty cool to see it come together, animations, level creation, portal jumps.
The basic hardware on the ds makes 3d pretty approachable. Ive found opengl overwhelming in the past. It seems like a fun platform to make games on, but idk if there is any active ds homebrew communities. Anyway sharing because i thought it was cool, hard to find anyone that seems to be to interested. I thought about getting a 3ds but they are surprisingly expensive now
Instead of building scrips here and there I'm attempting my own everything app. Lets see if that's a good idea :).
Starting with android home screen and widget sync to server/desktop. So e.g. calendar notifications happen desktop first, then escalate to mobile etc. Also phone as mousepad (for using my projector from bed). Just feature creeping it all in without regrets so far.
In general I feel like feature creep needs to be reevaluated. UX must not be destroyed, but features cost less now.
I have or am planning:
- escalating reminders
- always on display
- upcoming meetings / calendar
- have "website + prompt = widget" app that needs integration
- want 2 tier prio email filter (important, personal, ignore rest)
- android launcher with decent ergonomics (match "ff" to firefox, most used prioritized, launch with enter etc.)
- maybe some agent integration
Bearicorn.com
It’s a drop-in replacement for Redis written in Rust. Most if not all of your client code should work without issues. Outperforms in many areas and has more out of the box features like proto storage, raft/swim, and encryption at rest.
I’m pretty proud of it, and I hope you’ll give it a shot and open bug reports. :)
There is a surprising amount of edge cases that can cause ChatGPT or others to misunderstand your pages. Some models can handle div based tables, some want alt tags but cannot understand title tags, etc.
I built the tool to check your site as close as possible to what a human would see and then compare it with LLM's.
It was a weird journey trying to tease this info out of the models, they will happily lie, skip checking sites or just make things up.
Today working on adding chat history search (FTS5) and OpenRouter Nano Banana 2 support.
A project that I launched on HN that became a business. Simplescraper rode the no-code wave of a few years back ('instant structured data without parsing html').
Now working on increasing the surface area for AI agents: MCP support, screenshots API, and (experimentally) x402[1]
It suggests to me that the underlying architecture probably isn't too complicated, so I'd wish for an open-source solution

Also launching a supabase security scanner. If someone wants a free scan hit me up. Includes POCs and verification before and after remidiation. Goodbye false positives.
For now it uses UX patterns to make it easy to remove uninteresting articles and keeps a record of your read and saved articles. All locally of course.
I’d like to make it into something we can share quality content with one another eventually. For now I’m focusing on making it good enough my entourage will want to use it
It's called Peekl, and is available on Github. Tho it's still in what I'd called "alpha". Lot of new features to come!
It's a cross platform productivity app that lets you block apps, websites and games until you reach a set of verifiable goals such as walking 10,000 steps, physically going to the gym or finishing all your tasks on your to-do list.
I just finished the Android version a few weeks ago!
Multitrack field recorder with automatic cloud sync for iPhone. I use it for hi-fi recording of band practice and sharing demos with bandmates/collaborators. Great way to send stems too as it runs on the Mac as well and has a built in mixer. There's a social graph so you can send someone a session by typing in their handle and granting access.

I've been searching, posting, chatting on various platforms for more than a decade now. context-use allows me to turn all those years of data into context that I can bring to my favorite agents.
I have a bigger idea, too: I have a theory that a lot of enterprise group productivity software is really a species of social media. ATProto is an interesting basis for software that organizes workflows that incorporate agents.
Had a lot of fun doing it and it's more user friendly than trying to read off lists from stream aggregators online that have a lot of ads etc.
First ever go at something like this so any feedback is appreciated!
Building CiteLLM, an API that extracts structured data from PDFs and returns exact source locations for every field.
There's also a widget so you can add click-to-verify to your own app in a few lines of code.
Click any value, jump straight to the highlighted source in the PDF.

Stack is 15+ Go microservices on k3s. Cross-lingual semantic search is fun. Spanish query returns English calls with no translation code.
I went full TDD with the app so it was easy enough to build the logical parts of it. The UI is fairly simple, but whenever I found that Claude did not understand exactly what I wanted, I gave it a screenshot/image of a design and it did things pretty well.
It’s a CLI tool that makes open-source LLMs installable like packages.
llmpm install llama3
llmpm run llama3
You can also package models with your projects so others can reproduce the same setup easily.
Website: https://llmpm.co

Would love feedback: https://appents.com/
There is a wealth of data that's behind CSVs and other data formats. This uses DuckDB as a common (local) database to cache and run queries against, and enables going across datasets for insights using LLMs.
I think the first step is standardizing HTTP 402 using traditional, familiar payment rails like Stripe, then we can move to things like on-chain or other rails later.
I am building https://stripe402.com to try to make it dead simple for those building APIs/resources to get paid per request through stripe without user's needing to sign up for accounts, get API keys, any of that normal painful workflow required today.

Now shifting to established SaaS companies adding AI assistants to their existing products. Some of them literally have people reading chats full time, so they actually value the experience.
Building https://lenzy.ai - 2 paid customers, 2 pilots, looking for more and figuring out positioning.
Established companies adding AI assistants is interesting because they already have baseline metrics to compare against. They know what good user experience looks like in their domain, so when the AI chat experience is terrible, it's obvious.
What's the biggest gap you're seeing between what these companies think they need to measure vs what actually matters for AI chat quality?
Picked up some more small Xilinx Zynq 7020 dev boards for a quick micro-positioning vacuum-stage control driver. Yeah it was lazy, but I don't have time to spin a custom PCB board these days... or hand optimize LUT counts to fit smaller prototypes.
Also, doing a few small RF projects most people would find boring. =3
Locally running fully working steganography in the browser.
Create and insert entire files into pngs, mp4, pdfs and jpgs. The site is a static website that loads a wasm bin that does everything in browser with wasm. So no login, or network calls.
Essentially impregnate images and videos that open normally in your browser, but have a full file system with a full gallery mode for images, pdfs and images inside. videos do seek and stream so even if you embed a 4GB video file, it opens quite fast and just works.
Once I'm done with this project I'm planning on making a series of YouTube videos going into the code and the algorithms.
I'd be very interested to see your tutorial when it's done!

I'm building an identity verification platform for age verification. I set it up as a nonprofit because I think this is a public good that should be provided by governments. It's mostly a proof of concept right now. My long term goal is to get state DMVs using it (or something like it).
It already runs pretty smoothly. Next steps are adding a way to make playlists and listen to them right there, without leaving the page. Check it out and let me know what you think! All feedback is appreciated!
It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.
This was an excuse to ship a mobile app for the first time and get familiar with supabase.
After these last few bugs are fixed, its ready for a semi-public TestFlight with our friends who have kids.
The basic idea is that an utterance often has a gap between its surface form and its actual function in context. For example, a sentence like “Do you know what time it is?” may look like a question, but pragmatically function as criticism, pressure, or a prompt for reflection.
Mimesis tries to represent an utterance not just as text, but as a structured object with separate layers for: - `core`: semantic meaning and emotion - `will`: communicative purpose and influence - `flow`: discourse framing / progression - `exp`: surface realization
I’ve put together: - an English/Korean whitepaper - a schema spec - a working interactive demo
Still early, but I’m interested in whether something like this is useful as an intermediate representation layer for LLM systems, agent workflows, or discourse analysis.

I've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude code daily, but putting LLM’s into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an open API and ships an MCP server, so it connects to whatever you want to use LLM-wise. They can read, search, create, and edit documents through the API. The core product is just a docs tool that tries to be good at being a docs tool:
- Real-time collab with live cursors
- Fast — no embedded databases or heavy view abstractions slowing things down
- Hierarchical docs, drag-and-drop, semantic search
- Comments, version history, public sharing
- SSO, RBAC, audit logs, webhooks
This project makes use of existing database infrastructure and parses data from multiple banks including caveats and quirks of some banks improper handling of data.
This project aims to ease the work of accountants and administration as currently a lot of correcting mistakes and pairing to the correct invoice is done manually.
The project is made in python however the modularity we set ourselves to implement allows for quick, easy and hassle free corrections of code with use of project schematics, like builders, dependency injections etc. Discovered a great tool for running tests efficiently https://docs.astral.sh/uv/ .
Also for data retrieval from a remotely located database. DO NOT USE pyodbc, USE mssql library. pyodbc is unoptimized in terms of receiving high amounts of streamed data, it can't keep up. That alone has dropped the time of execution from 18 minutes down to about 20 seconds.
Also making use of typer and data classes for ensuring correct types of data.
Also been spending some time on my old side project https://infrabase.ai, an directory of AI infra related tools. Redesigned the landscape page (https://infrabase.ai/landscape), going through product submissions and content, optimizing a bit for seo/geo.
Here are the current features - Closet — Add clothing items with photos, category, color, brand, and tags. Visual wardrobe with hanging rod and shelves for browsing by category - Worn / Hamper tracking — Mark items as Clean, Worn, or in the Hamper to track what needs washing - Outfits — Build and save multi-piece outfits, organized by occasion - Weekly Schedule — Assign saved outfits to days of the week - AI Stylist — Get outfit suggestions powered by DeepSeek AI, with live weather integration - Preferences — Set style profile, favorite/avoid colors, occasions, and custom styles - Onboarding — First-launch questionnaire to seed your closet with basic wardrobe pieces
I'm still awaiting approval from Google Play and Apple. I'd love to hear what kind of features y'all would want in an outfit organizer app too.
But once all the low level operations are done, my plan is to implement an A2A Agent as the sole Agent listed in the AgentCard at $SERVER_ROOT/.well-known/agent-card.json, which is itself an "AgentListerAgent". So you can send messages to that Agent to receive details about all the registered Agents. Keeps everything pure A2A and works around the point that (at least in the current version) A2A doesn't have any direct support for the notion of putting multiple Agents on the same server (without using different ports). There are proposals out there to modify the spec to support that kind of scenario directly, but for my money, just having an AgentListerAgent as the "root" Agent should work fine.
Next steps will include automatically defining routes in a proxy server (APISIX?) to route traffic to the Agent container. And I think I'll probably add support for Agents beyond just A2A based Agents.
And of course the basic idea could be extended to all sorts of scenarios. Also, right now this is all based on Docker, using the Docker system events mechanism, but I think I'll want to support Kubernetes as well. So plenty of work to do...
A fun simulation game of prod breaking where you have to race to troubleshoot and fix the issue. Great for SREs, devs devops, founders and teams to learn in a non prod environment but feels real.
We are in beta and would love feedback!
Was on show hm the other day https://news.ycombinator.com/item?id=47323915
Built a Cythonized Icecast2 implementation I've wanted for years: https://github.com/lukeb42/cycast
Built a p2p Kanban board that fits in a single .html file and uses only the Python stdlib for LAN discovery https://github.com/lukeb42/kanban_p2p
Developed a p2p legislature that scales from a small team of 3 users to countries of tens of millions of people: https://gist.githubusercontent.com/LukeB42/deb887691f13dee9c...
Developed a small SPA framework inspired by React, Ractive-Load and hn.js: https://lukeb42.github.io/vertex-manual.html
Updated a news archival service for Python 3.x: https://github.com/lukeb42/harvest
Made a scriptable IRC client inspired by irssi and mIRC: https://github.com/lukeb42/scroll
and worked on a couple of my company's products.
It's mainly for censorship evasion (should be much harder to block than the regular centralized VPNs), but also for expats to access geo-blocked domestic services.
It's at the MVP stage and honestly it evoked much less interest in people than I hoped it would, but I'm still going on despite my better judgement.
But anyway, I've started to learn Go. By doing a vertical scrolling shooter with embiten. Kinda like fitting a square peg into a round hole. No, it's not public and will probably never be.
Studying how do do a memory pool for actors, since it doesn't look like garbage collection and hundreds of short lived bullet objects will mix well.
The filtering was easy, but RSS doesn't do "from the beginning" (RFC 5005 exists, but is mostly unused), so scope crept into a webpage-to-RSS tool that lets me convert favorite.site/s/archive - autodetection of the article structure was a fun side quest.
The whole thing is a little function engine (Yahoo Pipes called), so the final goal is `merge(archive, live_feed) | drip(N items per D days)` to have the archive transition seamlessly into current content. I expect I can push that live tomorrow or so.
And of course Podcasts are just RSS, so hey, let's skip reruns. That's doable with filters on the episode description, but with history in place I'll add title similarity checking. I'm trying to think how to recognize cross-promoted episodes too, without having to crawl every podcast.
Importantly, Sponder's _not_ a client. There are enough clients, any many are great. Each implements some subset of features, so Sponder's an intermediary that consumes and publishes pure RSS for us to use anywhere we want.
Project two started over the weekend and is the NYTimes' Pips, but colors. You're building a stained glass window with regional constraints, and the big difference from using dominos is colors can mix. Also, triangles! The engine works, and I'm designing the tutorial and first handful of puzzles now.
- Plask ( https://plask.dev ) — Google Analytics (GA4) connected analytics dashboard for people who ship multiple products. I got tired of manually checking separate GA4 properties for all my apps and SaaS projects, and setting up individual MCP integrations for each felt like overkill when I just wanted a quick overview. So I built a single dashboard that connects all your GA4 properties, runs statistical anomaly detection, sends alerts when something breaks, and generates AI weekly digests. Free tier for 2 properties, Pro at $9/mo.
- Kvile ( https://kvile.app ) — A lightweight desktop HTTP client built with Rust + Tauri. Native .http file support (JetBrains/VS Code/Kulala compatible), Monaco editor, JS pre/post scripts, SQLite-backed history. Sub-second startup. MIT licensed, no cloud, your requests stay on your machine. Think Postman without the bloat and login walls.
- APIDrift ( https://apidrift.dev ) — Monitors changelogs for APIs, SDKs, and libraries you depend on so you don't get blindsided by upstream breaking changes. Scrapes docs, diffs changes, classifies severity with AI, and sends digest emails. Track your dependencies, get alerted when something breaks. Free tier covers 3 sources with weekly digests. Built with Next.js, Supabase, and Gemini Flash.
- Mockingjay ( https://apps.apple.com/app/id6758616261 ) — iOS app that records video and streams AES-256-GCM encrypted chunks to your Google Drive in real-time. By the time someone takes your phone, the footage is already safe in the cloud. Built for journalists, activists, and anyone who needs tamper-proof evidence. Features a duress PIN that wipes local keys while preserving cloud backups, and a fake sleep mode that makes the phone look powered off during recording.
- Stao ( https://stao.app ) — A simple sit/stand reminder for standing desk users. Runs in the system tray, tracks your streaks, zero setup. Available on macOS, Windows, Linux, iOS, and Android.
- MyVisualRoutine ( https://myvisualroutine.com ) — This one is personal. I have three kids, two with severe disabilities. Visual schedules (laminated cards, velcro boards) are a lifeline for non-verbal children, but they're a nightmare to manage and they don't leave the house. So I built an app that lets you create a full visual routine in about 20 seconds and take it anywhere. Choice boards, First/Then boards, day plans, 50+ preloaded activities, works fully offline. Free tier is genuinely usable. Available on iOS and Android.
- Linetris ( https://apps.apple.com/app/id6759858457 ), a daily puzzle game where you fill an 8x8 grid with Tetris-like pieces to clear lines. Think Wordle meets Tetris. Daily challenges, leaderboards, and competititve play against friends.
Not similar to linetris but its tetris meets a block puzzle
We're also trying to use AI more thoughtfully than just bolting on a chatbot. We're planning to consider each workflow our customers need and how AI might help speed them up - even letting them build custom AI workflows. I think most businesses (especially smaller businesses) don't want to work at the level of Claude Code, Codex, etc. They want to work on higher level problems - build this dashboard, connect these data sources, invoice this customer, etc.
Aside from that, we've noticed that the basics really matter, so we're trying to nail that first.
We're definitely a bit delusional, we're just 3 people, we're doing it without funding and the competition is stiff, but we really believe in the product. Additionally, I think a lot of CRMs go south by taking on too much VC that naturally pushes them to prioritize ROI instead of continually improving the product.
I'm an automation engineer, and I wanted to see if I could move from the "fragmented web" to a Single View Era. Instead of just jumping between isolated SaaS silos, BiamOS uses a built-in Chromium webview with persistent sessions (Ghost-Auth) so the local LLM can interact directly with the DOM.
The goal isn't just another browser; it’s a desktop layer where the AI "reads" your active context (Gmail, Notion, Slack) and generates a unified UI based on what you’re actually doing. It’s about making the apps disappear into a single, agentic dashboard.
Stack: Electron 34, React 19, Hono, SQLite.
It’s early alpha, but I’m curious: Do you think the future of OS design lies in "Generative UI" replacing traditional window management?
I did this in response to my trainer blowing me off.

I am working on Plain Invoice (https://plaininvoice.com) — A free invoice generator for freelancers and small businesses. No signup required — just fill in your details, pick a currency (40+ supported), and download
the PDF or email it directly.
I built it because every invoicing tool I tried either required an account, had a paywall after 3 invoices, or was way overbuilt for someone who just needs to send a clean invoice. This keeps it simple
— pick your invoice type (hourly, product, or fixed price), add tax/discounts if needed, and you're done.
Would love any feedback from fellow freelancers or indie devs.The idea came from the commit-push-wait-read-logs cycle that everyone seems to accept as normal when debugging CI. PipeStep parses your workflow YAML, spins up the right Docker container, and lets you pause before each step, inspect the container, shell in, set breakpoints, skip or retry steps. It deliberately doesn't try to replicate the full Actions runtime — no secrets, no matrix builds, no uses: execution. For that, use act. PipeStep is specifically for when something breaks and you want to figure out why without pushing 10 more commits.
Think of it as gdb for your CI pipeline. pip install pipestep, Python 3.11+, MIT, requires Docker.
I'm dogfooding it heavily. The bugs at this point tend to be in card formatting. I ended up delaying the introduction of TeX/MathJax until I had quite a few cards written, and man oh man, it's tedious to go back and fix that formatting in hundreds of cards.
The real question: does it work? I _think_ so. I'm learning, and I feel like I'm retaining more, and I think the general structure counteracts or compensates for most of my issues as a learner. I think the science is pretty solid, but I'm also experimenting in a few areas, so... eh, we'll see.
If anyone is interested in trying it out, you can use it for quite some time (several months, maybe a few years) without needing to provide an email address or sign up.
It is a forum application where each community is invite only. Think a cross between reddit/discord. The invite only architecture reduces trolls, spam, AI slop and promotes more substantive discussions.
Right now invitations are limited to 1 per day for each user in a community. You don't need an invite to join at the global level - but to join any community you must have received an invitation link. Still a major work in progress, right now working on expanding the flexibility of community creation and invitation logic. (allowing bulk invites, adding flexible invitation cool downs, etc).

Looking up the location of the ISS at a specific time is easy. Looking up the closest passes of the ISS to a specific location for the last 30 years on-demand is more complicated.
On one hand, I regret not having thought it could find a market and I now have to do this and plan a migration.
On the other, I saved a lot of time going to customers instead of building the boring side first... So I don't know what to think of it.
I find that most of the development work is now "ops" instead of user-facing features (either addition, removal, or polish) and am a bit perplex at this.
A "world" is a locally stored CRDT that contains the source code and data you store.
The home page, login and world editing experience is all built from within itself.
I originally made it a couple of years ago as a small proof of concept. A couple of weeks ago I started it over and have been using it as a project to work with Claude and learn approaches to coding with AI.
It's been a lot of fun.

AIOs are a black hole - we dont know when they appear and whats in it. so i creates a tool thats starts with GSC data and enriches it via AIO data
works good and the major finding by now
the best AIOs you can get are ..... none.
doesn't matter if you are in it or not - as soon as they show up the CTR to tour web-property goes down massively ~60% to 70%
the CTR on the AIOs are ~0%
Wondering if there are other similar tools out there which people love, and why ChatGPT/Gemini/Claude won't let you do the same in their native apps.

So dating sites/apps are selling dreams, and the owners know this very precisely - thats the reason why there is no innovation: How would you innovative a product to make it better if there are some "technical" limits on how "best" your product can be?
b) a "decent sized list" is ... do not get me wrong ... bringing you nowhere: As Markus Frind, POF founder, famously said: If your app has less than 100k active users, this means nobody likes it. My experience is, depending on target area (conutry? city? local community?) the number of 100k is by far too low - its rather around 500k-1m users - AT LEAST
c) In my country, there are some fo these "hyper local" oriented dating websites, mainly for "special needs", these are the incumbents, and most of them are on the market since 20+ years. And for sure: They also have only a search form and a userdatabase to whom you can chat. Its not blocked in a sense that they are activly working against new entrants - its rather the fact that most new entrants cant survive long enough to get brand & traction awareness. Trying to launch a successful (niche)dating app with a marketing budget below 50m is going to fail, I promise.

You write user stories, start it up, and it loops through them one at a time. Fresh context per story, progress tracked in markdown between iterations. One clean commit per completed story. Has a TUI for watching it work and supports running multiple PRDs in parallel via git worktrees.
Built it because a lot of the "autonomous coding" tooling out there felt overly complex and opaque. Chief is intentionally lightweight and transparent. Everything is just markdown files and git. No magic.
The basic idea is that when one failure fans out across 20 services, you often end up with 20 alerts and 20 separate investigations, even though there is really just one root cause. I’m using distributed tracing to build a live model of how errors propagate through the system, and then exposing that context directly at each affected service.
Longer term, I want this to become a very high-precision RCA engine. Right now I’m looking to try it with a few early design partners that already have a lot of tracing data, especially OpenTelemetry or Datadog APM users. I'll love to chat with some folks who would be willing to try it out!

I recently added the possibility to describe what kind of widgets are to be used via a yaml file, as an option. This may not sound like a huge win, but so far what I like here is that it becomes easier to modify individual widgets without having to sift through code; and it works for more programming languages too. Any customization for the widget, including method-invocations if necessary, can be done via a yaml file now. There is of course a trade off in that the yaml file can become a bit complex (if the GUI uses many widgets), so for the most part I use this for smaller widgets/components that do one specific functionality (or, few specific functionalities). For instance, a GUI over wget. Then if other larger programs need that, I make this small widget more useful and flexible.
The distant goal is to actually use a simple DSL that also would allow average Joe to customize everything in a very easy manner; and to have a widget set that can be used for as many different parts possible including wonky ideas such as having a whole operating system as a GUI available one day (a bit like webmin, but not limited to what webmin does; for instance, I'd also have games such as solitaire, reversi and so forth). I'd like to see how far that idea can go, but it is just a hobby so I can only invest little time into it.
I have been using online courses and youtube forever and they all have converged on a similar format. Basically, adapt a textbook to slides and add voiceover. Sometimes they'll be animated. Not for everyone but I like it for passive learning.
Being a web developer I always thought video was a strange way to deliver this information - you can't even copy the text! Videos are also hard to make and heavy on bandwidth. So after iterating on different approaches to this over the last few years, I finally started on a new iteration called useful.
Currently on rev1, so early days: https://github.com/ohmstone/useful/tree/rev-1
There are a few more things I want to add to it but I want to get back to what I was doing (the bass guitar stuff). So I will make few of these website-as-video courses based on my projects to try and prove the concept.
Some of the nerdier features useful has:
- Uses state of the art CPU-based TTS with voice cloning, realistic enough to not be distracting
- Very simple markup language to create the visuals
- Extensible slide content with simple plugin system
- Full website export with complete SEO/social metadata
- Export is a PWA, so it caches nicely and can work offline
- Self-hostable
- Export is optimized for low bandwidth, so it loads way faster than a video and uses <1/10th of the data when served with brotli
- Minimal dependencies
Beyond my own use-case I figured it might be useful for others creating courses. One stretch-goal would be for people to turn what they are learning via LLMs into low-bandwidth courses like this so we don't have people burning energy asking the same questions and watching the same 4K videos.
Already launched biz-in-a-box.org and a life-in-a-box.org spinoff as frameworks to replace every entity's QuickBooks. I'm using them myself for every project my agents are spinning up.
Stealth project is related to classpass but for another category of need that won't go away even in the age of AI that really is only possible with critical mass of supply to meet existing demand. Super excited cus there's no better time to build with unlimited agents that scale without people problems.
Lastly, can't wait to run local LLMs so no longer limited by tokens/money.
AM3 - (Allied MasterComputer or Artificial Mind, version 3) - An attempt to make a symbolic AI that approaches the capacities of a LLM. An LLM makes variations on the same code and schedules those variations to play in "games". The results allow the LLM to make further changes.
Most of the work as of today is in a branch, can see the language spec at https://github.com/cretz/duralade/blob/initial-runtime/docs/..., and some samples at https://github.com/cretz/duralade/tree/initial-runtime/sampl....
May not amount to anything, but the ideas/concepts of this durable language are quite nice.
https://github.com/dbos-inc/dbos-demo-apps/blob/main/python/...
Admittedly the lang spec doesn't do a great job at the justification side, but the engine spec adjacent to it at https://github.com/cretz/duralade/blob/initial-runtime/docs/... that has sections showing CLI/API commands can help make it clearer where this runtime is unique.
With nao we are exploring the fact that agents are good to work with filesystems, so we help people getting the context into the filesystem and then you can plug our agent loop on top (on anything else).
The most exciting part is working with sandboxes and emulating filesystems. So at the moment the filesystem is local, but it could be a bucket or a database that we emulate as real filesystem for the agentic loop, all of this can also be mounted to sandboxes, and in the end you can do data transformations all in isolation with control on the context.
The focus is on the interfaces: there's a reading view that keeps you locked in without drowning in information, and a voice mode with karaoke-style word highlighting. Also built an iOS app for research on the go, releasing that soon.

A pro bono tech consultancy for local (Stavanger, Norway) non profits. The idea is to help them use tech to better deliver on their mission. Last week I built a little bookmarklet for a non-profit to surface some of their data buried in a SaaS tool ... which will make their apple pressing operation easier.
New features shipped last month:
- Adaptive practice: LLM generates and grades questions in real-time, then uses Item Response Theory (IRT) to estimate your ability and schedule the optimal next question. Replaces flashcards; especially for math and topics where each question needs to be fresh even when covering the same concept. - Interactive math graphs (JSXGraph) that are gradable - Single-image Docker deployment for easy self-hosting

It's a VS Code extension that implements a Kanban board backed by markdown files. It's set up to allow you to communicate with GitHub Copilot chat via markdown files, so you have a clear permanent record of your considerations, decisions and actions. I'd been getting great results with a similar but more manual workflow, so I built this to make managing the markdown files easier and to give me the ability to visually organise with some shortcut commands.

Recently downloaded Qwen3-coder-next 80b model and been vibing with it to introduce Qt6 and write a dead simple (aka ugly) crossplatform GUI to it so that other people can use it on their Macs and Linux machines. Letting a LLM wreak havoc on your project feels bad, I constantly have to reign it in and rollback the repo once it starts looping due to writing something that doesn't compile, making it going back and forth between doing and undoing changes.
An important feature for me was improving the recipe discovery experience, you can build a cookbook from chefs you follow on socials (youtube for now), or import from any source (Web, or take pic of cookbook etc) - it then has tight / easy integration into recipe lists.
Utilising GenAI to auto extract recipes, manage conversions, merge/categorise shopping lists etc - as-well as the actual recommendations engine.
If anyone is interested in beta testing / wants to have a chat I'll look out for replies, or message mealplannr@tomyeoman.dev
Basically OpenClaw but with investing dashboards for my portfolio, additional tools specifically for investing, and exploring an AI-Human collaboration on researching economics (check the 'community' tab).
The data models are all in markdown and Excel so that there's no lockin and you can manually edit positions, personalities, etc.
This comes from frustration around most investing tools basically scraping your personal data + forcing you to lock into subscriptions. I think it's now possible to just vibe code most of what one needs, aside form raw data subscriptions.
It's all open source, too: https://github.com/wgryc/athena-os
You can either use your own Anthropic/OpenAI key to play, or buy credits. I also have a free non-commercial version on my github you can fork.

Right now, actively building and growing https://OpenScout.so which is a tool for tracking mentions on Reddit, Linkedin, Twitter and HN. This is primarily made for early stage SaaS founders to help them with brand visibility problem.
Also, I don't support bots so we will never built bot solutions. This is against most of the ToS of platforms. I started this because I truly realised that building has commoditised and the go to market is the real deal. This tool helps with that. I'm going to add more features and I would love for you to try it.
Currently adding support for exposing Postgres schemas for each app to use. The goal is that with a shared Postgres instance, each app should be able to either get a dedicated schema or get limited/full access to another app's schema, with row level security rules being supported.
Currently my mini-projects includes:
* 0% USA dependency, aim is 100% EU. Currently still using AWS SES for email-sending and GCP KMS for customer data key encryption for envelope encryption.
* Tool output compression, inspired by https://news.ycombinator.com/item?id=47193064 Added semantic search on top of this using a local model running on Hetzner. Next phase is making the entire chain envelop encrypted.
* "Firewall" for tool calls
* AI Sandboxes ("OpenClaw but secure") with the credential integration mentiond above
It started because my wife watches Chinese dramas and new episodes never have subtitles for our language. Turns out thousands of people have the same problem — Arabic speakers watching anime, Russian speakers following Turkish series, Persian speakers catching up on K-dramas.
Supports 40+ languages, works with any video link or direct file upload. There's also a Mini App inside Telegram for a more visual experience.
Most monitoring tools alert every time anything changes. That usually ends up being navigation tweaks or small copy edits. After a while the alerts just get ignored.
Adversa focuses on meaningful updates instead. It detects changes across competitor pages and uses AI to summarise what changed and why it might matter.
I originally built it because I was manually checking competitor pricing pages and changelogs. I also wanted something practical for smaller SaaS teams. A lot of existing tools are either enterprise-priced or the free tiers are too limited to be useful.
Still early and trying to learn what people actually want from this kind of tool.
A friend of mine used to work for a real estate company and said his company and their competitors were always at loggerheads and complaining about each other breaking rules etc. this would have stoked the fire a little!
I was sick of getting cross-eyed when looking at tables in raw markdown and was just running it locally. This weekend I realized it might be useful for others.
The goal was simple as possible UX. Open url, drag and drop or paste into wysiwyg -> very readable and editable markdown. No sign up, no tracking, no fuss.
Of note, if you copy from the richtext mode, it copies raw markdown. The inverse is done with paste.
Based on feedback, I am working on very optional cloud-sync for as cheap as I can make it.
This has taken over my life. I took a week off of work to finish it.
This project was based on dogfooding, and every feature is something I wanted and now use daily. This is the most fun I have had in years.
That webapp I made in a week, is now indispensable to me as the key to human in the loop AI work. Truly, what a time to be alive!
I was really trying my best for friction-less UX on this project. I would appreciate any feedback on how I did, either by comment or the feedback button.
If you’ve used H3 the semantics should be familiar. The biggest differentiator is the fact that cells have exactly the same area globally, for why this matters see: https://a5geo.org/docs/recipes/a5-vs-h3
Since starting the project last year and providing implementations in TypeScript, Python and Rust it’s been great to see a community grow, porting or integrating into DuckDB, QGIS and many more: https://a5geo.org/docs/ecosystem
The idea is pretty simple: SQLite is amazing, but once it’s running in production you basically have zero observability. If something weird happens (unexpected writes, schema changes, background jobs touching tables, etc.) you only find out after the fact. It tries to solve that without touching application code. It's a Rust agent that runs next to your sqlite file, and connects to the server where everything is logged in. My current challenge right now is encryption and trust, mostly.
Curious if others here are running SQLite in production and if you would be interested in something like this.
While the main app is closed sourced, the rails engine that handles all the rss feeds is open sourced here: https://github.com/dchuk/source_monitor
I have another version of source monitor getting by published soon with some nice enhancements
- Tilth: Smart(er) code reading for humans and AI agents. Reduces LLM token use and cost by ~40% (benchmarked) https://github.com/jahala/tilth
- mrkd: Native macOS .md viewer (+preview in Finder) that imports iTerm2 and VSCode themes https://github.com/jahala/mrkd
- O-O: Self-updating articles concept with polyglot (bash/html) files. No server, no database. https://github.com/jahala/o-o
Also used the new Navigation API (and some Shadow DOM) to build a cheap, custom client-side rendering (sort of) into my site (https://taro.codes), and some other minor refactors and cleanup (finally migrated away from Sass to just native CSS, improved encapsulation of some things with Shadow roots, etc).
I've been wanting to write a simple AI agent with JS and Ollama just for fun and learning, but haven't started, yet...
The idea is: you join a meeting, hit start on the app, minimize, and go do actual work (or go make a coffee). When someone says your name or any keyword(s) you set, you get a native macOS notification with enough context to jump back in without looking lost. It uses whisper and is 100% local and doesnt leave traces, also very OE friendly.
Would love to hear what you think, especially if you're drowning in meetings too.
To date it's handled more than 70k orders, ingested nearly 10m telemetry records, has been extremely reliable, is almost entirely self-contained (including the routing stack so no expensive mapping dependencies) and is very efficient on system resources.
It handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.
The insight: the friction in getting testimonials isn't that clients don't want to help – it's that a blank "leave a review" box produces mediocre one-liners. SocialProof guides them through structured questions ("what was your situation before?" / "what changed?") so you get a compelling before/after narrative automatically.
Free tier: unlimited testimonials. Just launched and looking for feedback from anyone who deals with client testimonials.

Planning to package this as a workshop, so companies could be benefit from AI Native SDLC.
Put together the site yesterday https://getainative.com
Couple of the people I have worked with in the past agreed to meet me for a coffee, will pitch this. Fingers crossed.
https://github.com/nickbarth/closedbots/ I was also trying to do a simplified openclaw type gui using codex. The idea being its just desktop automation, but running through codex by sending codex screenshots and asking it to complete the steps in your automation via clicks and keypresses via robotgo.
I was stuck on this conversation problem. First version had a dead-end search box: six starter prompts, one referencing a tool that didn't exist. No follow-ups. No guided flows. Users got an answer and had to invent the next question from scratch.
Now the assistant explores your library with you. Tag discovery, color browsing, weekly digests, smart collections that auto-curate as you save.
Semantic search runs hybrid, keyword matching plus pgvector cosine similarity on 768-dim embeddings. Streaming responses.
Almost there. https://bookmarker.cc/

If any of you have already figured out a tool/workflow for this, I'd love to learn from your experience.
I'm finding language auto-detection to be a bit wonky (for example, it repeatedly identified Ladykracher audio as English instead of German). I ended up having to force a language instead. The only show in my library where this approach doesn't work is Parlement[1], but I can live with that.
On the whole this is looking quite promising. Thanks for the idea.
You context switch back and take 2 minutes (at best... much longer than if you were in the actual conversation paying attention) to answer. Now everyone else in the realtime conversation is waiting on your answer because you were expected to be in the conversation as well. That doesn't seem like good UX to me.
The system allows users to submit a JSON payload containing geocoordinates and mission requirements (e.g., capture_type: "4K_video" | "IR_photo"), the backend then handles the fleet logistics, selecting the optimal VTOL units from distributed sub-stations based on battery state-of-charge and proximity.
I've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude Code daily, but putting LLMs into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an API and an MCP server instead, so you connect whatever AI tools you actually want to use. The core product focuses on being a fast, solid docs tool. Real-time collab, fast — no embedded databases or heavy view abstractions, hierarchical docs, drag-and-drop, semantic search, comments, version history, public sharing, SSO, RBAC, audit logs, webhooks, etc. The stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package that exposes search, document CRUD, and comments — so Claude/ChatGPT can work with your docs without us reimplementing a worse version of what they already do. Happy to talk architecture or the MCP integration.
I posted about it recently on HN (https://news.ycombinator.com/item?id=47199062):
It is at a fairly early stage of development, so it's quite rough around the edges. It is developed and hosted in EU.
I have started developing it as a slim wrapper around Git to serve my own code, but it grew to such extent that I decided to give it a try and offer it as a service. It doesn't have much at the moment, but it already has basic pull requests. Accessibility is high priority.
It will be a paid service, (free for contributors) but since it's an early start, an "early adopter discount" is applied – 6 months for free. No card details required.
I would be happy if you give it a try and let me know what do you think, and perhaps share what you lack in existing solutions that you would like to see implemented here.
Opus has been amazingly useful at answering various statistics question that I had for it, and my current idea is a nested auction market theory inspired model. My biggest discovery is that replacing time with volume on the x axis (on a chart) and putting the bar duration on the bottom panel instead of volume normalizes the price movements and makes some of the profitable setups I've seen described in tape reading/price ladder trading courses actually visible on naked charts. A great insight I've gleamed is that variance should be proportional to volume instead of time or trade count. When plotted, it has the effect of expanding high volume areas, and compressing low volatility ones, which exposes trending price action much more readily. It honestly amazing, it's making me think that I could actually win at the trading game.
It's an auction website for schools, charities etc without the exploitative transaction fees.
My wife and I are pretty heavily involved in our son's school PTA (parent teacher association) and have helped run school fundraising events for a few years, so we feel sort of like domain experts in this area :)
The problem: AI agents run autonomously, calling LLMs and tools in loops. Without runtime controls, a single agent can burn $50+ in minutes, get stuck in infinite loops, or call dangerous actions without oversight.
What it does: - Cost ceilings — auto-kills when spending exceeds $X - Step limits — prevents runaway execution - Loop detection — catches repeated action patterns - Full telemetry — every step logged with tokens, cost, latency - Dashboard — real-time visibility into all agent runs
One decorator. That's it: @guard(max_cost_usd=10, max_steps=50) def run_agent(): agent.run()
Stack: Python SDK, TypeScript SDK, FastAPI backend, Next.js dashboard
Links: - GitHub: https://github.com/vijaym2k6/SteerPlane - PyPI: pip install steerplane - npm: npm install steerplane
Currently building: policy engine (allow/deny actions), remote kill switch, and framework integrations.
Would love feedback from anyone running AI agents in production! What controls do you wish you had?
I started small as a toy project, but gradually implemented full support for proper block context, flexbox layout, CSS variables, tables, etc. to the point where I have almost full support of all major CSS features (even math functions like calc(), min(), max()).
I'm cleaning up the code right now and will upload it later today or maybe tomorrow here: https://github.com/PureGoPDF
My library has support for @page rules, but that's actually pretty basic. I needed more advanced headers/footers and added support for in-html headers/footers like this: In your <body> you cna define headers/footers by wrapping content in a <section> tag. For example:
<body> <section> <header>... any HTML here, full CSS support</header>
<div> Some normal flow content</div>
<footer>Your footer HTML</footer>
</section>This structure is purely optional, but it's a really convinient way of designing pages with different styles in the same document. An HTML file can have any number of these sections meaning you can generate a PDF with different headers/footers.
Some other bits: It has support for 100% height that match the entire page, it can handle forced page breaks inside flexbox containers (Chrome doesn't even try ... just ignores it) and also follows page-break: avoid correctly - so it doesn't randomly split table rows for example.
The interesting part is that it’s not just about adding another database driver. I’m revisiting a big part of the codebase and introducing a framework that should make implementing support for new DBMSs much simpler. The goal is to make Greenmask more extensible so that the community can add support for other databases without needing to dig through the entire internal architecture.
Published the first beta of this new approach a few months ago, and now the focus is on stabilizing it and making it production-ready.

Separately I've been dipping my toes in to hosting things on the Scary Public Internet with an IRC server (as a backup/replacement for a personal Discord server) and a static Hugo website (for hosting fanfiction; there've been a few AO3 outages lately and I thought it would be fun to experiment with things like audio embeds). I'm a roboticist so my experience with webdev is pretty minimal, but I managed to figure out nginx eventually. I'm actually kind of frustrated with Hugo as an SSG because it really doesn't want you to run pandoc with custom arguments for markdown -> html conversion, and pandoc doesn't want to generate ToC on my markdown files, but the default markdown converter (goldmark) doesn't correctly process markdown italics inside of html tags (e.g. `<center>`), so my current compromise is to use pandoc on almost everything and goldmark anywhere I care about having a ToC.
The other project I am continuing to work on is Rad [1], a programming language tailor made for writing CLI scripts. It's not for enterprise software, it specializes specifically in CLI, offering all the essentials built-in, such as a declarative approach to arguments and generated help (as opposed to Bash where you have to roll your own arg parsing and help strings each time).
Started it because I wanted to develop from my phone while working on another project (Siteboon, a website builder). Open-sourced it last June and wasn't paying much attention. Looked up a few months later and it had a couple thousand stars. Now at 8.2k.
The interesting moment was when Anthropic launched Remote Control. Stars went up instead of down because their launch validated the use case but only lets you view and approve sessions, not fully control your instance. We went from 6.5k to 8.2k in a couple of weeks.
As many here, I've found that a single text file is all that I really need, but found that it makes it difficult to keep track of a variety of things. I was also trying to use the file as a simple project tracker, adding some tags like [BUG-N], and updating them by hand. Eventually, it became difficult to track the progress of things, since I had to jump around the file to look for updates.. or use grep.
I condensed the idea to just that - a very simple tool which manages "trackers", and has a simple filtering built in to "trace" the updates. I've been using it, since I've added the BE, and dogfooding it a bunch. Would love for fellow note takers to take a look. It's not perfect, but I'm keeping it around for myself :)
At this moment I’m working on improving the logic that decides when/how much to throttle the network.
Built it because I wanted to read more, but most reading apps either feel too passive or turn everything into social noise. What worked better for me was making reading easy to start: short 5–10 min sessions, pick up where you left off, minimal friction.
So the app is basically centered around habit formation, with stuff like notes, progress tracking, session extension, shelves, and simple organization.
I care a lot about keeping it quiet: no ads, no feed, no unnecessary clutter.
Still early. Mostly trying to understand what actually helps people read more consistently.
Currently only available for iOS, but might release an android version in the future.

A lot of existing databases are storage first, with everything else built around them. I have been exploring what it looks like if the database is closer to the application runtime itself, where state is live, queryable, and easier to reason about directly.
One thing I am prototyping right now is database-native tests.
Basically: what if integration tests were a database primitive?
CREATE TEST test::insert { INSERT test::users [{ id: 99, name: "Ghost" }]; FROM test::users | FILTER id == 99 | ASSERT { name == "Ghost" }; };
So not a wrapper, not a framework, not an external test runner.
A real test object inside the database.
The idea is that you could run these before schema changes, and make stored procedures or other database logic much easier to test without leaving the database model.
Still early, but it feels like one of those things that should just exist, especially for databases built around live application state.
The problem: every agent (Cline, Aider, Codex, Claude Code) has unrestricted access to your filesystem, shell, and network. When they process untrusted content — a cloned repo, a dependency README — they’re prompt injection vectors with full machine access. No existing tool evaluates what the agent actually does at the syscall level.
grith wraps any CLI agent without modification. OS-level interception captures every file open, network call, and process spawn, then runs it through 17 independent security filters in parallel across three phases (~15ms total). Composite score routes each call: auto-allow, auto-deny, or queue for async review. Most will auto approve - which eliminates approval fatigue.
Also does per-session cost tracking and audit trails as a side effect of intercepting everything.
Main gig: Trusted agents. We just shipped hardware based signing to web bot auth protocol.
I have worked with data for a while. I feel like our tools could be much better when it comes to "flow". I want an experience where you don't need to alt+tab to slack/images/another query. What if we put it all on a canvas? That's what Kavla is all about!
Since last month I've done a lot of improvements to the editor to make the "flow" better.
I've also read up on HMAC, Nonces and fun encryption stuff to create read only boards.
Here's one where I look at stack overflow survey for databases: https://app.kavla.dev/v/mqhg54o319doya4.67dbfee1ccd6caf638d3...
Snowflake users apparently make the most money!
This is a "full rewrite," because I need to migrate away from my previous server, which was developed as a high-security, general-purpose application server, and is way overkill for this app.
Migration is likely to take a couple more years, but this is a big first step.
I've rewritten the server, to present a much smaller API. Unfortunately, I'm not yet ready to change the server SQL schema yet, so "behind the curtain" is still pretty hairy. Once the new API and client app are stable, I'll look at the SQL schema. The whole deal is to not interfere with the many users of the app.
I should note that I never would have tried this, without the help of an LLM. It has been invaluable. The development speed is pretty crazy.
Still a lot of work ahead, but the server is done, and I'm a good part of the way through the client communication SDK.
Provisional patents went in recently so don't mind broadcasting to a wider audience beyond my poor, unknowing, testers

I'm working on getting instacart API access so I can build out the cart for the meal plan automatically, at which point I'm hoping this is a one click confirmation a week to keep interesting food flowing. Works great for scheduling baby meals as well!
I built a service that lets developers bundle remote files into a ZIP with a single POST request. You send a list of URLs, we fetch, package, and return a signed download link.
The problem: creating ZIPs from remote files (S3, R2, CDN) usually means downloading to a server, zipping locally, managing temp storage, and cleaning up. It's surprisingly painful at scale — especially with large files or thousands of items.
Eazip handles all of that. ZIP64 support for files over 4GB, up to 5,000 files per job, zero egress fees on downloads, and no infrastructure to manage.
Use cases so far: e-commerce photo bundles, document delivery (invoices/contracts), creative asset distribution, and backup/export tooling.
Free tier available, no credit card required. Would love feedback from the HN community.
Built with React Native/Expo. The hardest part hasn't been the sensor code, but rather designing interactions that feel natural rather than gimmicky. Each word needs to map to a physical action that actually reinforces the meaning. Solo dev, live in German app stores now. Previously co-founded another language learning startup (Sylby, partnered with Goethe Institute), so this is take two with a very different approach.

What sorts of topics do you enjoy learning about on Youtube?
I have no illusions that this is actually something in capable of building to an actual release-able state but it’s fun to tinker with.
The main goal is letting people analyze their games and improve by studying their blunders. It uses stockfish and AI for analysis. You can chat with your games like "Why would I do ___ instead of this?"
Also, there are the standard puzzles and openings type learning with improvement plans.
First release was in December for 1D cuts. Last month I released sheet cutting for 2D cut calculation. It's been working well for my own projects and it started getting consistent daily users since my last update in February. You can save projects now on the site for you to come back to later.
Any feedback is welcome. I'm always looking for what features to add next.
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.

I do wonder if the problem is not so much having a place to find LAN events but actually just having enough people put on LAN events in the first place. It feels like a thing of the past with how much less people interact in person these days. It's a shame because LANs are awesome!
Have you thought about ways to make it easier for people to host LAN events? Or does this solve that as well? I guess a solution would require matching random people together. Happy to discuss more - nick at onthe.town
> I do wonder if the problem is not so much having a place to find LAN events but actually just having enough people put on LAN events in the first place.
Sort of! I did a lot of research on this before I built lan.events. There are more gamers than ever, but LANs dropped off during COVID lockdowns despite surveys showing an increasing interest in in-person events. More or less, it's actually a venue problem. Running events has incredibly thin and risky margins for something that by its very nature needs to be planned out months in advance. Everything around the events are becoming prohibitively expensive: venues, vendors, equipment rentals, etc are all eating away at the ceiling gamers will pay and the floor that organizations can charge from.
LAN.events helps tackle this by decreasing the cost per ticket and shifting that cost to the customer rather than the event manager. We don't introduce minimum event costs or percentage based pricing which lets event managers keep or give back more profits. There is more I can do in this space, but that's the biggest way I can contribute right now.
I'll have to investigate LEGOpress.
I am fundamentally interested in ontology, relationships, and epistemology. I map ontological placement of entities as a foundational mapping of wealth, power, influence etc.

It's like OpenClaw but actually secure, without access to secrets, with scoped plugin permissions, isolation, etc. I love it, it's been extremely helpful, and pairs really well with a little hardware voice note device I made:
Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click.
Since my last month, I shipped the asset marketplace and the LLM builder. Artists can now upload tilesets and characters, and unlike itch.io, assets drop directly into the editor. You can preview how they'll actually look in-game before using them [1].
An other problem I kept running into: even with a no-code editor, users don't know where to start. So now I'm extending it with a coding agent. Describe the game you want, and it assembles it — pulling assets from the marketplace, wiring up the event system, and using all the building blocks I've spent the past year extracting. Multiplayer, mobile controls, pathfinding, NPC behaviors — the agent doesn't build any of it, just reaches for what's already there.
Once the LLM assembles it, users will have a game ready to work on, and will still be able jump into the editor and tweak everything [2]. Here's an example of what it can already make [3] (after a lot of prompting), and the goal is to reach games like this one I built with the manual editor[4].
Hoping to release the AI mode in a week or two. The manual editor is live at https://craftmygame.com in the meantime.

1. Live Kaiwa — real-time Japanese conversation support
I live in a rural farming neighborhood in Japan. Day-to-day Japanese is fine for me, but neighborhood meetings were a completely different level. Fast speech, local dialect, references to people and events from decades ago. I'd leave feeling like I understood maybe 5% of what happened.
So I built a tool for myself to help follow those conversations.
Live Kaiwa transcribes Japanese speech in real time and gives English translations, summaries, and suggested responses while the conversation is happening.
Some technical details:
* Browser microphone streams audio via WebRTC to a server with Kotoba Whisper * Multi-pass transcription: quick first pass, then higher-accuracy re-transcription that replaces earlier text * Each batch of transcript is sent to an LLM that generates translations, summary bullets, and response suggestions * Everything is streamed back to the UI live * Session data stays entirely in the browser — nothing stored server-side
---
2. Cooperation Cube — a board game that rotates the playing field
Years ago I built a physical board game where players place sticks into a wooden cube to complete patterns on the faces.
The twist: the cube rotates 90° every round, so patterns you're building suddenly become part of someone else's board. It creates a mix of strategy, memory, and semi-cooperative play.
I recently built a digital version.
Game mechanics:
* 4 players drafting cards and placing colored sticks on cube faces * The cube rotates every 4 actions * Players must remember what exists on other faces * Cooperation cards allow two players to coordinate for shared bonuses * Game ends when someone runs out of short sticks
---
Both projects mostly started as things I wanted to exist for myself. Curious what people think.
The problem was the ML dependencies. The backend uses BGE-small-en-v1.5 for embeddings and FAISS for vector search. Both are C++/Python. Using them from Go means CGO, which means a C toolchain in your build, platform-specific binaries, and the end of go get && go build.
So I wrote both from scratch in pure Go.
goformer (https://www.mikeayles.com/blog/goformer/) loads HuggingFace safetensors directly and runs BERT inference. No ONNX export step, no Python in the build pipeline. It produces embeddings that match the Python reference to cosine similarity > 0.9999. It's 10-50x slower than ONNX Runtime, but for my workload (embed one short query at search time, batch ingest at deploy time) 154ms per embedding is noise.
goformersearch (https://www.mikeayles.com/blog/goformersearch/) is the vector index. Brute-force and HNSW, same interface, swap with one line. I couldn't justify pulling in FAISS for the index sizes I'm dealing with (10k-50k vectors), and the pure Go HNSW searches in under 0.5ms at 50k vectors. Had to settle for HNSW over FAISS's IVF-PQ, but at this scale the recall tradeoff is fine.
The interesting bit was finding the crossover point where HNSW beats brute-force. At 384 dimensions it's around 2,400 vectors. Below that, just scan everything, the graph overhead isn't worth it. I wrote it up with benchmarks against FAISS for reference.
Together they're a zero-dependency semantic search stack. go get both libraries, download a model from HuggingFace, and you have embedding generation + vector search in a single static binary. No Python, no Docker, no CGO.
Is it better than ONNX/FAISS? Heck no. I just did it because I wanted to try out Go.

It pulls a list of birds reported on eBird in your county in the last 2 weeks and you ask preselected questions like the the color or size to whittle down the possibilities. I also made a matching game that uses the same list and you have to match the name to a picture of the bird. I set it up for California for now. I wanted to get more comfortable with SQL and APIs.
Feedback welcome.
It's a bad ripoff of the much, much more fun metazooa (https://metazooa.com/play/game). I kike it but it gets real annoying when your down to 1 of 10 bats or something. I've been using it to read and edit Wikipedia articles for undeveloped pages.
Free Math Sheets is a tool to generate math worksheet PDFs (and the answer keys if required). Currently it supports K-5 but I want to expand it to higher levels of math (Calculus, Physics, you name it!). You select a bunch of different options and then generate it. All in the front-end. No back-end or login in required. https://www.freemathsheets.com
If you are interested in helping out or forking it, here is the github repo github.com/sophikos/free-math-sheets
The paid project is Numerikos. I am going for something in between Khan Academy and Math Academy. I like the playfulness and answer input methods from Khan Academy (but it is linear, doesn't have a good way to go back and practice, etc.). I like Math Academy's algorithm (but it has multiple choice answers, yuck! and is easy to get stuck and doesn't have a good way to explore on your own). Currently Numerikos supports 4th and 5th grade math lessons and practice. The algorithm is based on mastery learning like Numerikos, but you can also see a list of all the skills and practice whatever you want. I am also working on a dashboard system where you can build your own daily/weekly practices for the skills you care about. Next up is 6th grade math and placement tests.
The idea is that _any_ user-facing tool, whether an app, worksheet generator or whatever, will need something like this for content, so I'm making this available for free and hoping for others to build on top of it.
I'm sticking to university-level stuff because I feel that school-level, especially math, is over-saturated already.
Technically, it is currently built as a React app, but that is mostly me sticking to tools that get out of my way. Generating PDFs or Anki files should be relatively straightforward.
Basically an API wrapping a cyclic graph where rules govern the state transitions / graph traversal (i.e. rules around handing off work between agents and the associated review, rollback and human intervention escalation logic).
It's mostly just to teach myself about multiagent patterns and what blend of "agentic autonomy" and deterministic / human governance gets the best results with the current set of (Anthropic) tools available.
I don't really know what I'm doing w.r.t AI, but having 15 years of industry SWE experience (high-availability distributed systems and full-stack web dev) on top of a fairly-solid CS education I feel like I know what the results of a working system should be and I'm learning a lot about the AI pieces as I go through trial and error.
Generally it feels like there are lots of ways the next generation of AI-assisted coding workflows could work best (beyond just "AI helps write code", I mean) and the results will be as much about the tooling built around the AI bits as it will be the improvements in models / AI bits themselves (barring a theoretical breakthrough in the space).
Trying to figure out what my personal dev workflow will look like in the middle of this evolving landscape is what led to this project, very much a scratch my own itch thing.
In the past month, as suggested by the previous user, I have added support for kicad schematic libraries. The kicad schematic libraries files are converted into circuitscript format and can be directly imported into circuitscript code. To support the large number of components in the kicad libraries, I had to improve the import functionality and also implement some caching to speed up the imports. With the kicad schematic libraries available now, it provides a larger library of components that can be used in circuitscript projects. The converted libraries can be found here: https://gitlab.com/circuitscript/kicad-libraries
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) for work in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
Please check it out and I look forward to your feedback, especially if you are also exploring alternative ways to create schematics. Thanks!
The first thing I cleaned up was TCL-Edit <https://gitlab.com/siddfinch/tcl-editor>, a small Tcl/Tk text editor I wrote a long time ago. After seeing the Rust clone of Microsoft EDIT, I realized the obvious next step was to build a Tcl/Tk clone of the Rust clone of Microsoft Edit. Recursion shouldn't be limited to code.
I also built a tiny URL system in Perl <https://gitlab.com/siddfinch/perl-tiny-url>, meant to run locally. The idea is simple: short URLs for internal/VPN resources per client. I usually spin up a small daemon (or container) per client and get a dashboard of links I use frequently or recently.
Security is intentionally minimal since it's local, which conveniently lets me ignore authentication and other responsible behavior.
Goal for the year: Continue to open stuff42.tar.gz, pick something, clean it up just enough, and release it, and not have it by the end of the year.
Might even choose a language that might even be described as "modern."
I have built npm for LLM models, which lets you install & run 10,000+ open sourced large language models within seconds. The idea is to make models installable like packages in your code:
llmpm install llama3
llmpm run llama3
You can also package large language models together with your code so projects can reproduce the same setup easily.
Follow the docs here: https://www.llmpm.co/docs
Pro tip for your use case: Checkout the `llmpm serve` section
We're constantly pulling info from official sources, and using AI to group and summarize into stories, and continue to share reporting from trusted, vetted journalists.
The result is news with the speed and breadth of getting updates straight from the source, and the perspective and context that reporting provides.
Still ramping up, but I'd love to hear feedback:
And thank you for flagging the scroll thing. I hadn't seen it, but will check.
That said, it's both combining various updates into a cohesive timeline of a story, writing the summaries, and assigning it an urgency level which helps in sorting and some other tasks.

Playing it for 1h, it reminds me of how much fun and how simple lot of games where back then - and these were blockbusters.

Over the last year I've been hacking on Table Slayer [0] a web tool for projecting DnD maps on purpose built TV-in-table setups. Right now I'm working on making hardware that supports large format touch displays.
Since I also play boardgames, this past month I threw together Counter Slayer [1], which helps you generate STLs for box game inserts.
Both projects are open source and available on GitHub. I've had fun building software for hobbies that are mostly tactile.
(If you're a local reading this and enjoy DnD w/ roleplay and acting, email's in my profile)
My favorite features are: - custom layout and drag and drop to change window - auto resume to last working session on app starting - notifications - copy and paste images directly to Claude Code/Codex/Gemini CLI - file tree with right click to insert file path to the session directly
OH and it works on both Windows and MacOS! Fully open source too!
I've wanted this for a long time, so I finally started building it. I've had a lot fun!
- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)
- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference
- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more
Give it a try!
This is the kind of project that creates something from as little as possible, where the only things you need to get started are a very basic RISC-V assembler and a computer or emulator to run it on.
I don't have anything interesting to show yet because I just started yesterday, but one day I will show you.
It is a pretty fun project
Sounds like a fun project -- like a more interactive version of Football Manager.
One thing I am exploring is that, with LLM (and enough $ to pay the tokens) you can filter out offenses and hate speech in player communications.
All typed message is effectively translated by the LLM as “coach speech” and what is put in the UI is the LLM output. Sure, it is not exactly the player words and can get expensive, but I think it can be a good solution
It's been a ton of fun to work on. Every subsystem is still flaky so I run into the wackiest bugs imaginable. I'm really grateful for the resources[1] and incredible tooling[2] that enable me to work out my frequent mistakes. I can hardly fathom how Torvalds did this with just his PC running Minix!
No idea how long I'll keep working on it. I think I'd be pretty happy if I got a real-world, non-trivial program running on top of it, but in the meantime it is serving as a good distraction from life worries at least :]
[1]: Intel 80386 Reference Manual, Linux man pages, wiki.osdev.org, various datasheets and the occasional query to ChatGPT free tier.

Since we're both working on a similar project, I think it could be fun to talk about OS development and share our findings (and weird bugs!) I have this same username just about everywhere, so do reach out if you're interested! Best of luck with your project either way :]
I have a fairly novel approach to operating it, and in the case of one time theft prevention security through obscurity is actually a great approach. The assailant only has a short time to pull the car apart and solve the puzzle, couple that with genuine security techniques, a physical aspect, and it should be pretty foolproof.
It can still be towed away, etc, not much to be done there except brute force physical blocks. Most cars get stolen here to do crime in that night so it's not as common.
Or time to pull the car apart
Adding a puzzle is brilliant and I would love to read a blog about this. Post it here on HN ;)
It’s like netflix for language, where users can select/create their personal bilangual stories.
I had quite a lot of feedback from HN, friends, random people on the internet and trying to solve the common pain points and find my way around to make it geniunely useful.
- Most people said it’s hard to come up with a story, so I added url grounding. Also added buttons (including HN :)) so people can just click click and get their stories at their level with their interests.
- Made sure people can generate stories without ever signing up
- Each word is highlighted while being read, and the meanings can be checked with a tap. I also added an option for users to read the sentence for being checked how good their pronounciation is.
- Benchmarked 7 different models to get the fastest & highest quality story generation (it’s gemini now) and it’s insanely fast. I might share more about it on the webpage because I am an engineer and I enjoy this stuff lol.
- Added CSV import in Use my words so Anki users can just import their words to study.
- Also people can download their stories as pdf so they can send it to their kindles.
- I am working on a ChatGPT app, so people can just say “@DuoBook give me a Dutch/English story on latest Iranian events” within ChatGPT, but I am a bit afraid that it might be costly lol.
It has been a lot of fun to learn about Vulkan / GLSL and the GPU execution model to figure out why the CPU is so much faster than the GPU. I'll be open sourcing the code soon but so far I'm documenting my journey in a series of blog posts. First one of the series is https://www.execfoo.de/blog/deltastep.html
One thing that I've been very happy with has been "org-people", now on MELPA, which allows contact-management within Emacs via org-mode blocks and properties. It works so well with the native facilities that it's a joy to work on.
I've been learning a lot of new things while I've been expanding it now it has a bigger audience (e.g. "cl-defstruct" was a pleasant surprise).
Why? Many yarncrafters painstakingly build spreadsheets, or try to bend existing general purpose pixel editors to their will. It's time consuming & frustrating.
Along the way, I've solved a bunch of problems:
- Automatic decreases (shapes the hat) / overstitching markers (shows when multiple colors are used in the same row)
- Parameterized designs, like waves, trees, geometric shapes. No more manually moving an object by a couple of pixels, it's a simple click & drag.
- Color palette merging (can't delete a color if you already use it in a pattern!)
- Export to PDF (so you can print it or stick it on a tablet)
- Repeat previews (visualize the pattern as it repeats horizontally)
If you drag a shape near the right edge of the canvas, you'll see it "wrapping around" onto the right edge.
This reflects the 3D reality of a hat!
I just deleted that particular if-statement so you should be able to export.
It's not anything fancy, but gets the job done. Uses pdf-lib.
It's like a carfax but for your home, although the intention is more to create an interesting historical narrative that inspires people to care about the history of their home rather than as a tool for inspecting home issues before buying.
My target customer is realtors who want to inspire buyers to take on historic homes that may need a lot of work. Also home owners themselves of course.
If this became the norm, somehow, it would be a really helpful tool for both buyers and sellers.
The most fun is a simple Claude Code in a loop, Boucle, which builds and iterates on its own framework[0][1].
The first thing it built was a persistent memory. Now it has finally built itself a "self-observation engine" after countless nudging attempts. Exploring, probing, and trying to push back the limits of these models is pure chaos, immensely frustrating, but also fun.
Aside from that, some sort of agent harness I guess we call them? Putting together a "system" / "process" with automated reviews to both steer agents, ground them (drift is a huge pain), and somehow ensure consistency while giving them enough leeway to exploit their full capabilities. Nothing ready to share yet, but I feel that without it I’ll just keep teetering on the edge of burnout.
I've given myself 6 months
It's a bit scary basically 180ing like this but I figure if I don't try it now I never will
I've already started prototyping various ideas, and to be honest just sitting down and spending time doing this has been really quite lovely
One thing I'm finding fun is slowly unearthing what I actually find interesting
I started with messing around in minecraft and tinkering with rimworld-like game ideas, but I'm slowly moving away from them as I've been tinkering more and more
Don't get me wrong, I do want to revisit them at some point in the future, but I do find myself circling more around narrative, simulations and zachlikes
It's a bit of an odd mix and in some ways they look like paradox style games, but I'm well aware that taking one of those behemoths on is going to be a bit silly, so I'm trying to slim down until I get to a kernel that I actually find enjoyable tinkering with
A toy if you will
Currently I'm trying to work out if there's anything interesting in custom unit design, basically unpicking how games like rollercoaster tycoon's coaster design maps to stats like excitement ratings and seeing how that might mix with old school point buy systems
It feels like it might be small enough to be a good toy and I'm having fun tinkering with it, but I have no idea whether other people will xD
It might honestly be too niche for anyone and I've successfully optimised for an audience of one :shrug:
She sells a product with 16 different printed parts, and she prints the parts in bulk batches across 7 different pause points, some of which have pause points for embedding magnets.
The idea is to integrate inventory management and print scheduling into the tool, which will be nice.
I have working so far: * Pulling camera images * Pulling the currently printing file, including the preview image (rendered in bambu studio and bundled with the print; standard for bambu studio), and the pause points * A dashboard with projected timing information * Notifications about jobs starting, stopping & pausing * Remote printer control
Next on the list: * Delayed printing - schedule a print to start in the night. Mostly useful so that if there's a pause point we don't leave a print paused for hours on end. * Print queueing - manually build a list of prints so that after switching plates we can just "next print" for a printer * Print scheduling - select a quantity of print files or groups of files to print, and have it schedule the prints, including projected switch times, to maximize printer utilization by avoiding jobs ending at night * Tracking magnet & filament usage, and integrating BoM and production quantity tracking.
I've been mostly AI coding this, but I've go in to make it extract out components, etc. And I lay down and enforce the DB schema. I've had to ask it to back out a few things entirely. And I've had to give it the Bambu API docs I found github. But it's been going pretty well.
The other part is the upfront cost. I bet we'll get to injection molding in the next few months as revenue allows, and we're going to start exploring it this month I think. We'd like to keep things local, though we know we'll still have to contend with knock offs sooner than later.
PS - The results are entirely obvious.

For all the places it's bad at, AI has been fantastic for making targeted data experiences a lot more accessible to build (see MotherDuck and dives, etc), as long as you can keep the actual data access grounded. Years of tableau/looker have atrophied my creativity a bit, trying to get back to having more fun.
This is an app that’s been bouncing around in my head for over a decade but finally got it working well enough for my own purposes about a year and a half ago.
I was thinking of a google maps kind of "here you are, here's your walking path of interesting trees" potentially, or something else that could tie the overview to the street experience - on the backlog!
https://www.inclusivecolors.com/
The current web tool lets you export to CSS, Tailwind and Figma, and uses HSLuv for the color picker. HSL color pickers that most design tools like Figma use have the very counterintuitive property that the hue and saturation sliders will change the lightness of a color (which then impacts its WCAG contrast), which HSLuv fixes to make it much easier to find accessible color combinations.
I'm working on a Figma plugin version so you can preview colors directly on a Figma design as you make changes. It's tricky shrinking the UI to work inside a small plugin window!
Essentially the hardest step is to throw yourself into the big enough fire that easier and simpler things would seem like a child's play.
Even less time is fine but throwing yourself at the hard stuff you don't know how to do is smart, cus after that If You Were to repeat it, it'd be easier for you to do.
Niche or not, it's about being satisfied of the project.
So it's more about who you are as a person, I like to throw myself into fire and I fully understand that I might get disenchanted quickly, but simpler tasks or projects will be easy easier to make.
I've got to admit throwing myself into the deep end is always how I've learned
It's been difficult at times, but in the end I've always found it more rewarding
I think I'm just struggling with trying to do something so different to what I've spent a lot of my career doing whilst being really aware this is such a challenging field
It's a bit like when I first decided to go all in on being a founder over 15 years ago
I probably could have saved myself 2+ hours of debugging if I had simply stopped working off of assumptions that my driver code was wrong (it was, but that just took reading the spec and checking out some drivers for reference) and doing a root cause analysis with `objdump` or through QEMU. Still surprised how far you can go with vanilla debugging prints - when I started this project, I was sure that I'd become fluent in gdb as a byproduct, but I stopped using it once it would break when the stack became corrupted and haven't tried it since.
Discussion is the reason I made the jump from lurking to having an account on HN. Happy to talk - reached out to you on twitter. And good luck to you as well :^)
Otherwise the map tiles are coming from OpenFreeMap [1] which are indeed based on OSM.
Next steps I'm interested in are including economic + ecological benefits of the trees, highlighting potential pests / invasive species, maybe some other basic info about the species sourced from Wikipedia.
I like how you've got different icons for different types of trees; I've been thinking about how to encode DBH data as well but haven't settled on anything yet.
DBH I'm doing for the "size" right now, though I'd love to figure out how to get canopy shape/size as well, and height where possible. (and then maybe proxy height a species level from DBH, since that's more common).
(apologies for belated response)
I started developing a city builder called Metropolis 1998 [1], but wanted to take the genre in new directions, building on top of what modern games have to offer:
- Watch what's happening inside buildings and design your own (optional)
- Change demand to a per-business level
- Bring the pixel art 3D render aesthetic back from the dead (e.g RollerCoaster Tycoon) [2]
I just updated my Steam page with some recent snapshots from my game. Im really happy with how the game is turning out!
[1] https://store.steampowered.com/app/2287430/Metropolis_1998/
[2] The art in my game is hand drawn though
> Both adults in a family will now own a car. This is required since there are not other transportation options, and sidewalks are optional.
Is this temporary or are you planning to release it like this? SimCity leaned into euclidean zoning (separate industrial/residential/commercial zones) and pocketable cars which needed no parking, and thus failed to properly showcase how ugly car-centric cities actually are. I’m sure they did it because it made for an easy gameplay loop/balancing but I’d hope we could come up with more realistic and interesting mechanics in 2026
Both adults owning a car will be dynamic/based on the city once there are more transportation options.
I'll also be adding options so the player can control how difficult traffic management is.
Ive hired out help for the pixel art, and then I enhance everything with shaders (tech art).
If you're gonna make a game as an indie, you need to figure out ways to fill in your skill gaps. The competition is brutal. If you can't do it/dont have time to learn and do it, then the only other option is to hire out.
or
A lot of studios are formed from people (cofounders) who depart larger studios, so if you really want to get into the industry, you could start there and network.
Will you do a native Linux release, or has it been tested with Proton?
Also, just from watching the video and screenshots in the Steam page, it seems like a crazy amount of work. Are you doing everything by yourself?
I'll be looking into porting during early access. I've heard the game runs on Linux with a compatibility layer though.
I do everything except the pixel art and buildings. It is a crazy amount of work!
I've commented on it before: https://news.ycombinator.com/item?id=39810716
So like (C++):
vector<uo_map<int, ObjStruct>>
Though I wish I went with a vector<vector<vector<ObjStruct>>> approach now a days <chunk_id>, <floor>, <object>
Didn't realise you'd swapped to isometric, it's looking fabulous!
Did you roll your own engine, I know Godot has issues scaling past a certain number of simulations.
Also working on a language for embedded bare-metal devices with built-in cooperative multitasking.
A lot of embedded projects introduce an RTOS and then end up inheriting the complexity that comes with it. The idea here is to keep the mental model simple: every `[]` block runs independently and automatically yields after each logical line of code.
There is also an event/messaging system:
- Blocks can be triggered by events: `[>event params ...]`
- Blocks can wait for events internally
- Events can also be injected from interrupts
This makes it easy to model embedded systems as independent state machines while still monitoring device state.
Right now it’s mostly an interpreter written in Rust, but it can also emit C code. I’m still experimenting with syntax.
Example:
module WaterTank {
type Direction = UP|DOWN
let direction = UP
let current = 0
[>open_valve direction |> direction]
[>update level |> current]
[
for 0..30 |> iteration {
when direction {
UP -> !update level=current + 1 |> min(100)
DOWN -> !update level=current - 1 |> max(0)
} ~
%'{iteration} {current}'
}
]
[>update level |> when {
0..10 -> %'shallow'
11..15 -> %'good'
16.. -> %'too much!' then !open_valve direction=DOWN
}
]
}The content is hand picked from tiktok, Instagram, Facebook, Reddit and other AI generating platforms.
Honestly I don't know where I'm going with this, but I felt the urge to create it, so here it is.
I learned how to optimize serving assets on CloudFlare.

It just won an award! It was awarded Players' Choice out of 700 daily web games at the Playlin awards: https://playlin.io/news/announcing-the-2025-playlin-awards-w...

Im also building https://www.keepfiled.com, a microsaas to save emails (or email attachments) to google drive
I almost forgot, I also built https://statphone.com - One emergency number that rings your whole family and breaks through DND.
I love building. I built all these for myself. unfortunately I suck at marketing so I barely have customers.
It's an addictive slot machine where I pull the lever and the dials spin as I hope for the sound of a jackpot. 999 out of 1000 winning models do so because of look-ahead bias, which makes them look great but are actually bad models. For example, one didn't convert the time zone from UTC to EST, so five hours of future knowledge got baked into the model. Another used `SELECT DISTINCT`, which chose a value at random during a 0–5 hour window — meaning 0–5 hours of future knowledge got baked in. That one was somehow related to Timescale hypertables.
Now I'm applying the VIX formula to TSLA options trades to see if I can take research papers about trading with VIX and apply them to TSLA.
Whatever the case, I've learned a lot about working with LLM agents and time-series data, and very little about actually trading equities and derivatives.
(I did 100% beat SPY with a train/out-of-sample test, though not by much. I'll likely share it here in a couple weeks. It automates trading on Robinhood, which is pretty cool.)
Pipeline so far has gone like this:
* Use the search engine's API to query a bunch of depravity
* Use qwen3.5 to label the search results and generate training data
* Try to use fasttext to create a fast model
* Get good results in theory but awful results in practice because it picks up weird features
* Yolo implement a small neural net using hand selected input features instead
* Train using fasttext training data
* Do a pretty good job
* for (;;) Apply the model to real a world link database and relabel positive findings with qwen to provide more training data
Currently this is where I'm at

It needs an NSFW filter because some people want it, especially certain API consumers.
I have been working on it as side project for over two years and now, with funding from the EU for the next 2.5 years, I hope I can make of it a real product for everyone to use that can compete with the likes of Excel and Googl;e Sheets.
I can oly say, I am overly, off the Moon excited
We’ve continued to get some paid customers and have exited beta last week, given everyone seemed to be quite satisfied and there hadn't been requests for changes, only some specific search providers.
Because of bots there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a couple of days for free, reach out with your account number and we’ll set that up!
Thanks.
P.S.: Because people have asked before, our tech stack is intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such — search can be done without JS), using Deno in the backend (for easier TypeScript), PostgreSQL for the DB, and Docker for easier deploying.
Hister is basically a full text indexer which saves all the visited pages rendered by your browser. It provides a flexible web (and terminal) search interface & query language to explore previously visited content with ease or quickly fall back to traditional search engines.
Here's a little summary of the background/motivation/beginnings: https://hister.org/posts/how-i-cut-my-google-search-dependen...

Website: https://hister.org/ Read-only demo: https://demo.hister.org/
how does it handle forms or homepages with refreshed content? for example, the home page of hackernews - will it always show the latest feed from the last time i had a connection or will it store each time ive visited it ?
Currently it overwrites the previous content with the latest if there is any change, but I'd like to add option to store diffs as well in the future.
The front bump out leaks when we get driving rain. I installed some flashing but that wasn't enough, it's still leaking. So I'm working on that so I can close up the big hole in the ceiling some day.
The prior owners filled in the old coal chute with literal bags of cement sort of artistically placed in the hole in the brick foundation. So I'm trying to figure out what masonry tools and skills I'll need to close it up proper.
I'd like to build my kids a playhouse of some sort, sketching out some designs for that.
Very exciting on the playhouse. What kind of things will it have?
I'm expecting my first this year so have a ways to go before I get to work on that project
I'm building a lightweight screen recorder for macOS. It supports lots of features you'd expect from a professional screen recorder such as ProRes 422/4444, HEVC/H.265, and H.264, capturing alpha channels and supports HDR. Frame rates from 24 to 120fps. Can capture system audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac. Still early, but happy to hear feedback!
The stock firmware is horrible but the community has this firmware called CrossPoint. I wanted to be able to upload, manage files etc. from my iPhone on the go and also send over web articles. So I build this app CrossPoint Sync https://crosspointsync.com to do just that.
I've already published it on App Store and pending publishing on Android. The community is niche and has also been using the app, so its been fun building for my use and in turn also getting good feedback from community.
If you are using the Xteink and CrossPoint firmware, then give the app a try.

It worked well enough that the novels were better than the median novel aimed at my son's age group, but I'm pretty sure we can do better.
There are web-based tools to help fiction authors to keep their stories straight: they use some data structures to store details about the world, the characters, the plot, the subplots etc., and how they change during each chapter.
I am trying to make an agent skill that has two parts:
- the SKILL.md that defines the goal (what criteria the novel must satisfy to be complete and good) and the general method
- some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)
- a python file which the agent uses as the interface into the data structure (I want it to have a strong structure, and I don't like the idea of the agent just editing a bunch of json files directly)
For the first few iterations, I'm using cheap models (Gemini Flash ones) to generate the stories, and Opus 4.6 to provide feedback. Once I think the skill is described sufficiently well, I'll use a more powerful model for generation and read the resulting novel myself.
One of the issues I encountered initially was that the LLMs were repeating a small set of actions and never trying some of the more experimental actions. With a bit of prompt tweaking I was able to get them to branch out a bit, but it still feels like there's a lot of room for improvement on that front. I still haven't figured out how to instill a creative spark for exploration through my prompting skills.
It has been quite exciting to see how quickly a few simple rules can lead to emergent storytelling. One of the actions I added was the ability for the agents to pray to the creator of their world (i.e. me) along with the ability for me to respond in a separate cycle. The first prayer I received was from an agent that decided to wade into a river and kneel, just to offer a moment in stillness. Imagining it is still making me smile.
Unfortunately, I don't have access to enough compute to run a bigger experiment, but I think it would be really interesting to create lots of seed worlds / codebases which exist in a loop. With the twist being that after each cycle the agents can all suggest changes to their world. This would've previously been quite difficult, but I think it could be viable with current agentic programming capabilities. I wonder what a world with different LLM distributions would look like after a few iterations. What kind of worlds would Gemini, Claude, Grok, or ChatGPT create? And what if they're all put in the same world, which ones become the dominant force?
It feels like a small change, but it really makes sense in my brain and I'm glad I finally made it happen. My services feel properly positioned under these distinct brands. Now of course when I get time I need to redesign both of my own websites.
Ideas wise... I like the static website world. I use 11ty, but there are others moving in this direction. Clean, performant, simple html / css / js websites that should last for decades. I like the idea of publishing them to IPFS, creating an indie web with some permanence to it.
We just launched a portfolio for Director of Photography Joel Honeywell: https://joelhoneywell.com/
This is a simple static site, no CMS, built with 11ty.
I also intend to dig into how to integrate Emacs with tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, load it into the LLM's context window, and send it off for transcription. If the essay isn't already too long, I'll demonstrate how to gather forced-alignment data using local models such as wav2vec2-latin so I can play audio snippets of Latin texts directly from a transcription buffer in Emacs. Lastly, I want show how to leverage Gemini to automatically create multimedia flash cards in Org mode using the anki-editor Emacs minor mode for sentence mining.
The result is an experiment called fesh. It works strictly as a deterministic pre-processor pipeline wrapping LZMA (xz). The AI kept identifying "structural entropy boundaries" and instructed me to extract near-branches, normalize jump tables, rewrite .eh_frame DWARF pointers to absolute image bases, delta-encode ELF .rela structs with ZigZag mappings, and force column transpositions before compressing them in separated LZMA channels.
Surprisingly, it actually works. The CI strictly verifies that compression is perfectly reversible (bit-for-bit identity match) across 103 Alpine Linux x86_64 packages. According to the benchmarks, it consistently produces smaller payloads than xz -9e --x86 (XZ BCJ), ZSTD, and Brotli across the board—averaging around 6% smaller than maximum XZ BCJ limits.
I honestly have no idea how much of this is genuinely novel versus standard practices in extreme binary packing (like Crinkler/UPX).
Repo: https://github.com/mohsen1/fesh
For those who know this stuff:
Does this architecture have any actual merits for standard distribution formats, or is this just overfitting the LZMA dictionary to Alpine's compiler outputs? I'd love to hear from people who actually understand compression math.
Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more. Most recently, we added support for benchmarking (create custom dashboards tracking nav and value chart of subsets of your portfolio) and US stocks, etfs etc.

I'm also maintaining GodotJS, strongly typed TypeScript bindings for Godot, which is used to build the Breaka Club RPG (see first link):

https://milliondollarchat.com a reimagining of the million dollar homepage for the AI age. Not useful, but fun. A free to use chatbot that anyone can influence by adding to the context. The chatbot's "thoughts" are streamed to all visitors.
I have some barebones content at https://struggle-meals.wonger.dev/ and will be working on the design over the next few weeks. Some decisions I'm thinking about:
- balancing between personal convenience and brevity vs being potentially useful for other people. E.g. should I tag everything that's vegan/vegetarian/GF/dairyfree/halal/etc? Should I take pictures of everything? (I'd rather not)
- how simple can I make a recipe without ruining it? E.g. can I omit every measurement? should I separate nice-to-have ingredients from critical ingredients? how do I make that look uncomplicated? (Sometimes the worst thing is having too many options)
- if/how to price things? Depends on region, season, discounts, etc

KPT is a language app specifically targeted at explainable verb conjugation for highly inflected/agglutinative languages. Currently works for Finnish, Ukrainian, Welsh, Turkish and Tamil.
These are really hard languages to learn for most speakers of European languages, particularly English - we're not used to complex verb conjugations, they're hard to memorise and the rules often feel quite arbitrary. Every other conjugation practice app just tells you right/wrong with no explanation, which doesn't really help you learn when there are literally hundreds of rules to get right.
The interesting part was using an LLM to create a complete machine-executable set of conjugation rules, which are optimized for human explainability, and an engine to diagnose which rule is at fault when you get it wrong. There's several hundred rules needed for each language in order to cover all exceptions.
NB as a bonus it also works fully offline because my best practice hours are when I'm travelling and have poor connectivity.
I recently converted a bunch of stuff to be client side instead of server side (turns out running a real-time MMORPG server is expensive) so there's a new round of bugs I'm still resolving, but it's still fun to play:
I've become more and more interested in code that yields (coroutines etc, read this fascinating article on HN just a couple of days ago: https://willhbr.net/2026/03/02/async-inject-and-effects/ )
Can you share more about this? How the async model works? Why it does -- is it a performance guarantee given the RTOS comment? Or is it more about the state machine idea, and how or why does yielding every line (not, say, every state transition, though I have no idea if or why that would be more useful) relate to that?
I mostly just have lots of questions because it sounds fascinating, so if you're looking for an excuse to talk about it, please count this as that excuse!
I dunno if/how this could be taught, but I feel like half the battle is critical thinking with an adversarial mindset towards media -- who would make this, why would they want to show me, do I see anything that makes this impossible, is it worth engaging with in the first place, can I fact check this.
I'm trying to gamify the training to make the experience more appealing.
I store a "proof URL" on the backend, but I don't know if it makes sense to serve it to the end user. Also, a Reddit discussion is not necessarily a proof one wants. A fingerprint would be better, but not all images are generated with Google. That's another problem to be solved.
EDIT: Hm, I switched tab, away to write this comment, now that I switched back, it showed me that I clicked correctly. So it seems, that sometimes it just has huge delay in accepting my choice?
Edit: I don't see slow traces in Sentry. No idea what caused this. Also, voting goes through redis and the dB load is low. Weird. I probably have to add gunicorn workers.
Edit2: Bumped gunicorn workers from 2 to 4. Should be fine now, under the current load. Again, thank you for reporting!
It's SFW and localized to the most popular languages.
It'll also probably shut the mouth of those who think that they know better. This works with the driving license. Start a test with the whole family and watch the older men get a reality check.
Bracket City is great! Definitely one of my favorites
My only concern is that there is a buzzing noise if the app is in the foreground and some audio is playing in the background. This is on pixel 9a
Oh interesting, thanks for the bug report! I hadn’t heard that one yet. I’ll look into it
Thank you so much for keeping it going!
- I applied to showcase the game at the Portland Retro Gaming Expo with the Portland Indie Game Squad. They accepted me so I was able to showcase it at the expo for a day. This got me some players right off the bat
- I shared it on HN, Reddit, Mastodon, etc.
- The website Thinky Games wrote an article about it
- The YouTube channel Cracking the Cryptic shared it which got a lot of new players. More recently a couple of other YouTubers (Timotab and Stro Solves) have been posting videos regularly
- I link to it from my blog, and this unrelated rant went semi-viral in web dev circles: https://paulmakeswebsites.com/writing/shadcn-radio-button/
- Winning the award gave me more visibility and players
I've also tried using things like Instagram and Discord but haven't had much luck there. I don't really get how those platforms work.
To be honest I'm not great at marketing. I've just been experimenting and seeing what works.
---
I would say the most important thing is the game itself:
- I've worked hard to gather feedback and incorporate it into the gameplay.
- I focus on keeping the puzzles fresh and striking the right difficulty level. (Challenging but something most people can do in 10 minutes.)
- I built a sharing feature that ~300 or so people use a day
I think all my marketing would have been useless if people didn't like the game and want to play again and share it with their friends.
Unfortunately if a spammer called the StatPhone number, it would dial everyone. I thought about blocking or automatically categorizing but then you may miss an important call from an unknown number.
Most spammers are actually operating off of known lists, usually made off of some data leak.
I haven’t encountered that issue yet. I don’t have a great solution for that case.
If the first group doesn't pick up, it starts calling the second group, but first group continues to ring.
If the caller hangs up, all ringing is stopped.
The cool thing is if it encounters the native phone's voicemail, it hangs up and continues to ring so doesn't think it was a picked up call.
We do have our own voicemail that will eventually answer (user defined timing), which then transcribes and sends the voicemail+transcription to all the group members.
Pixie is more like quickbooks or any other record keeping software. We don’t employ the children, their parents do. And as long as the kids are doing legitimate work, it’s fair and actually the irs has a page on it. https://www.irs.gov/businesses/small-businesses-self-employe...
Best of luck. Super fun!
PS: Just a follow-up. There was a post here a few days ago about a research breakthrough where they literally just had the agent iterate on a single planning doc over and over. I think pushing chain of thought for SOTA foundational models is fertile ground. That may lead to an algorithmic breakthrough if you start with some solid academic research.
Ended up using ClickHouse - much smaller on disk, and much faster on all metrics.
- everything around Statistical Arbitrage
- you can adapt ideas from electrical engineering (phase detection etc.)
There is giant pool of ideas & methods you could apply.
It has enough information that it will continue to iterate for the next several hours.
It's all happening in a black box. I have no idea. My concern isn't trading but rather to get it to continuously improve unsupervised without lying or hallucinating.

The important thing is that is all those cases the engine is the same. I
I have subscribed for a month and will give it a try.
One feedback already though. Some of the German translations are...not great. For example, on the landing page under the "Not another AI tool". In English you write "We find it hard to do in a sensible, responsible, and respectful way." In the German translation its "Es fällt uns schwer, vernünftig, verantwortungsvoll und respektvoll zu handeln."
The German translation makes it sound like you (as in you as a company and person) have a hard time being respectful, not the actual AI implementation.
We are currently working with a professional technical translator for German (should get updated translations in a week or two) and will consider that for other languages, but it's quite expensive to do more of that right now.
I don't think Kagi is heading in a necessarily "bad" direction, though I don't agree with it, and I also think there's value in a product that's solely focused on private and personal search, that doesn't have to be as expensive, expansive (Drive, Maps, Email, etc.) or big (team and resources-wise) as they are.
I hope that makes sense!
Could you share more info about how you're building it? Like Kagi it wraps / reuses multiple other providers? How do you do that affordably, and how do you merge the results together into a good answer?
Initially we called all search providers and merged the results in a round robin fashion (so first of the first provider, first of the second provider, first of the third provider, then second of the first provider, second of the second provider, and so on), deduplicating them, but this was becoming very costly and inefficient once we had 3 and more search providers (most providers will return results within 500ms, but not infrequently one would take up to 2s or more — we timeout there, so I don't know if it'd take much more —, slowing everything down), so now we give everyone the choice of which providers to use first, and we pick results from the first two (we're actually considering switching to just the first, as costs are still a bit high and we don't want to increase pricing).
I hope that provides some more clarity! Happy to answer any more questions.
One bit of feedback from me, take it or leave it, but the name doesn't feel appealing or memorable. What does it mean?
There's no specific meaning, though I can't say I dislike the close name matches with Uruk-hai [1] and Uruk [2]! :)
Search is _incredibly_ hard, there are reasons why there are no real Google competitors.
Is Uruky using Yandex?
some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)
- What are these meant to be exactly? are these sub agents in the workflow or am i completely misunderstanding?
The idea is that on any 'turn', the AI model should be doing only one of those tasks. That's true whether it's in the main thread (with all the past context) or has just been launched as a subagent.
You can see an example of this pattern here in Anthropic's skills repo: https://github.com/anthropics/skills/tree/main/skills/skill-... (the repo has four separate skill.md files: a main SKILLS.md and then three others for specialist roles)
Whether they're run as subagents (a separate AI chat session with clean context) is a separate decision, and it depends on whether the coding harness supports that. https://agentskills.io/client-implementation/adding-skills-s...
I'm still trying to figure out the subagent delegation stuff.
"Man becomes, as it were, the sex organs of the machine world, as the bee of the plant world, enabling it to fecundate and to evolve ever new forms. The machine world reciprocates man's love by expediting his wishes and desires, namely, in providing him with wealth."
That said, two cases where I noticed the pattern:
Meal planning: I had a weekly ChatGPT task that suggested dinner options based on nutritional constraints and generated a shopping list (e.g. two dinners with 100g of chicken -> buy 200g). After a few iterations, it became clear that with a fixed set of recipes and their ingredients, a simple script generating combinations was enough. The agent's reasoning had already done its job — it helped me understand the problem well enough to replace itself.
QA exploration: I was using an agent to explore a web app as a QA tester. It took several minutes per run. After some iterations, the more practical path was having it log its explorations to a file, then derive automated tests from that log. The agent still runs occasionally, but the tests run frequently and cheaply.
Regarding your point about tasks that need individual reasoning every time — I think you're right, and that's actually the core of the idea. Not every task matures into a script. Extracting structured data from images probably stays deliberative if the images vary significantly. The cycle only applies to tasks that, after enough repetitions, reveal a stable pattern. The agent itself is what helps you discover whether that pattern exists.
Re creating puzzles, does this mean you have to manually do them one per day? Is there a way to automate them ahead of time (as in have an app generate a bunch of puzzles you can pick from or tweak)?
I’ve automated parts of the process. Once I have the words and clues I can autogenerate crosswords and pick the best one.
I’m hesitant to automate the creation of the theme, words, and clues though. I worry that the quality would go down but there may be some opportunities to speed up brainstorming there. I’ve been noodling on this.
Do you generally want feedback and have a preferred channel for it beyond hackernews comments?
The biggest benefit for me with StatPhone is the incoming callerID is the StatPhone number. So even if the kid's school is calling from a random number, on your phone it shows the StatPhone number and you know its a call pertains to your child.
Also grouped escalation, so if my father calls in an emergency, the kids get called first and then the in laws and our uncle.
Have you tried searching for meaningful words in other languages? Kagi means key in Japanese, for example. I've had luck with this approach before.
One downside is there’s no community for him around the books, but maybe that’s not a big deal.
