Cosmofy – bundle your Python code for Linux/Windows/MacOS

In plain words

Cosmofy is a development tool that bundles pure Python projects into a single executable file using Cosmopolitan Python, enabling the same binary to run on Linux, macOS, and Windows without modification. It simplifies cross-platform distribution by eliminating the need to create separate builds for each operating system. The tool is designed for Python developers who want to streamline deployment across multiple platforms.

  Clamshell- an experimental Python based shell2023 · github.com · ▲51

  About a month ago I started a suprisingly-not-that tricky project to build an experimental python repl that I could use instead of bash as a daily shell in windows, mac or linux. It"s more hack-for-exploration than a production ready shell, but here it is! Hope somebody finds it anywhere near as interesting to check out as I found making it. Disclaimer: I know about xonsh and love it (if you haven't heard of it, google it). This project is more pure python and less python and bash interacting - see the readme for more details.

  Talanoa▲341

  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…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
