Owlkettle – A Declarative user interface framework based on GTK 4

In plain words

Owlkettle is a declarative user interface framework built on GTK 4, launched in 2022. It enables developers to build desktop applications by writing UI code in a declarative style rather than imperative commands. The framework abstracts GTK 4's functionality to simplify interface creation, making it accessible to developers who prefer declarative programming approaches. It targets software developers building cross-platform desktop applications on Linux and other GTK-supported platforms.

  Talanoa▲343

  Hi 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…

  Pipes puzzle (a.k.a. Net) on a hexagonal grid▲537

  Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
