In plain words
Poica is a C library that brings algebraic data types and type introspection capabilities to pure C programming. It enables developers to work with advanced type systems typically found in functional languages while staying within C's constraints. The library is designed for C programmers who need structured ways to handle complex data types and perform runtime type inspection without external dependencies.

I just published a bidirectional code generation library. Afaik it's the first of its kind, and it opens up a lot of possibilities for cool new types of dev tools. The PoC is for ruby, but the concept is very portable. https://blog.luitjes.it/posts/monocle-bidirectional-code-gen...

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
