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.

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.…
