The idea is simple:\ninstead of sending requests to a single backend, route them through a layer that can switch to another backend if something goes wrong.

It:

checks backend health (latency, errors)\navoids unhealthy servers\nretries requests on another backend if needed

It’s designed as:

a fast routing layer (Rust)\na simple control API (Python)\nshared state via Redis

One thing I found interesting is that failover only works before the response starts — after that, switching isn’t possible.

Still early and mostly an experiment to understand failover and reliability better. This begun as internal experiment, after recent region outages.

Curious how others approach this problem in production systems.","time":1775542349,"title":"Show HN: System that keeps apps running when a server or region goes down","type":"story"}],[47672321,{"by":"mesahm","descendants":5,"id":47672321,"kids":[47672341,47672780,47673486,47672558],"score":3,"time":1775551343,"title":"Show HN: Niquests – A Requests fork, three years of catching Python's HTTP up","type":"story","url":"https://github.com/jawah/niquests/tree/v3.18.4"}],[47657165,{"by":"cloudkj","descendants":1,"id":47657165,"kids":[47658799],"score":1,"text":"I was looking through some of my past personal projects tinkering with reinforcement learning, and noticed that the REST/HTTP API for the OpenAI gym available at the time is no longer supported.

gymnasium-http-api is an attempt at bringing back the same type of language-agnostic support. It mostly wraps the forked and supported Gymnasium library, with some endpoints specifically for making it easier to render and visualize the training and learning process.

I built Pace, a Claude Connector that lets you connect all your wearables (Garmin, Polar, Whoop, 20+) with Claude.

You connect your devices once and can analyze your data with Claude. No Dashboard needed, just in natural language.\nI already use it everyday, especially the visualization tool in Claude makes this really cool to use.

Tools include: overview, sleep, training, activity, samples and trends.

Tech Stack: Python (FastMCP), Google Cloud Run, Google Cloud SQL (PostgreSQL) and Firebase

It is live and free to try (no Claude Pro/MAX Plan needed)..

Would love feedback, especially from people who've built MCP servers or use wearables seriously.","time":1775467365,"title":"Show HN: I just built a MCP Server that connects Claude to all your wearables","type":"story","url":"https://pacetraining.co/"}],[47650438,{"by":"srodriguezp","descendants":0,"id":47650438,"kids":[47658787],"score":5,"text":"A prompt tuned for Llama 3 often degrades on Mistral or Qwen — same task, different behavioral surface.

Works fully local via Ollama. Also supports OpenRouter for cross-hosted runs. No telemetry, no cloud dependency.\nBuilt with Python, Typer, Pydantic.\nHappy to go deep on the calibration algorithm or the tradeoffs in the scoring design.
