here's a web app I made that generates code for efficiently approximating mathematical functions. This is useful when performance matters more than perfect accuracy, for example in embedded systems.

The app uses Chebyshev expansions, which despite their theoretical depth result in suprisingly compact and readable code in practice. This code is generated for you and using it does not require any knowledge of the underlying theory.

I'm the founder of Flipt, an open-source (https://github.com/flipt-io/flipt) feature flag tool that I (and others) have been working on for the past few years.

About a year or two ago we added support for serving flag state from various non-relational declarative stores like Git, OCI, Object Store, etc.

Many of our users came to love the git-backed storage, as it allows them to keep their feature flags close to their code in there organization's repos. But they had one (rather large) ask, and that was the ability to use the UI to manage flag state changes and still use Git as the backend.

So today we're rolling out our hosted solution that does exactly that (and more soon).

I would love any feedback, questions, etc, or if anyone would give it a spin! Happy to extend the 14-day trial as well for anyone interested in providing product feedback.

Thanks!!","time":1725567343,"title":"Show HN: Feature Flags Backed by Git","type":"story","url":"https://www.flipt.io/"}],[39014313,{"by":"maguay","descendants":2,"id":39014313,"kids":[39017356,39014675],"score":13,"time":1705418860,"title":"Don't Add AI Chatbots to Your Product.
