Infat – Declaritive application assocation manager for macOS
Bello! Made this to help navigate the tumultuous process of navigating to a new machine on Mac when you have a number of custom utilities setup for editing particular files. This is designed to make that as easy as possible, and add some magic on top of that, like setting mailto handlers or anything else of that breed. Use XDG_CONFIG_HOME to keep it organized. Credit to https://github.com/moretension/duti for the original inspiration for the project. Happy to answer and help with whatever.

In plain words
Infat is a macOS tool that manages file type associations and protocol handlers through a declarative configuration system. It simplifies migrating custom utilities and editors to new machines by allowing users to define which applications handle specific file types and protocols like mailto links. The tool uses XDG_CONFIG_HOME for organized configuration storage, making it easy to set up complex application associations without manual macOS settings adjustments.

- DADevUtils.app – Developer Utilities for macOS2020 · ▲241
This is a project I've been working on since the start of Covid-19. I built an app so that I don't have to put data into online tools like JWT debugger, JSON formatter, URL decoder, etc... https://devutils.app The app works entirely offline and is open-source. I'm selling the pre-built version of the app to earn some revenue for my time. If you want to try the app but can't afford the price or don't have XCode to build the app, drop me an email (my profile), I'll be happy to provide you a free build. I would love to hear all the feedback/suggestions. Thanks!

Talanoa▲341Hi 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…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
