  4. cool-retro-term

    A good looking terminal emulator which mimics the old cathode display...

    Project mention: Show HN: A retro terminal text editor for GNU/Linux coded in C (C-edit) | news.ycombinator.com | 2024-08-30

    Love the look, definitely throwing me back to the halcyon QBasic days.

    Another way to achieve an old school raster style green screen aesthetic is to combine cool-retro-term with the minimal editor "micro".

    Project mention: How to prompt LLM to infer XSD from many XML documents? | news.ycombinator.com | 2024-12-05

    In case anyone is interested in the details, I am trying to infer the MuseScore MSCX format to ensure that my MusicXML => MuseScore generator at https://github.com/infojunkie/musicxml-mscx produces valid scores. I want to use all the supplied MSCX files in the repo https://github.com/musescore/MuseScore for inference.

  11. moonlight-qt

    Project mention: Show HN: Open-source GeForce NOW alternative with Stadia's social features | news.ycombinator.com | 2024-05-18

  12. zeal

    Offline documentation browser inspired by Dash

    Project mention: Patterns for Personal Web Sites (2003) | news.ycombinator.com | 2025-02-03

    Yeah, I keep thinking that CHM was the peak format for offline docs. Today we have Kiwix [0] and Dash/Zeal [1] – both amazing projects, but somehow they feel more complex, and the formats they use aren’t as ubiquitous.

  13. tiled

    Flexible level editor

    Project mention: Building Game Prototypes with LÖVE | news.ycombinator.com | 2024-12-31

    I built Twins of Caduceus (a snake-based game where you have to control two snakes simultaneously) entirely using Phaser 3. I've had mostly very good experiences with it as a batteries included framework (renderer, asset management, physics, input, etc.)

    It's a shame that the map/level editor is a eternal subscription fee with no fallback license. That means you're relegated to either building your own map editor or using something like Tiled.

  14. urh

    Universal Radio Hacker: Investigate Wireless Protocols Like A Boss

    Project mention: Goodwatch – A Ham Radio Wristwatch | news.ycombinator.com | 2024-07-03

    Cheap, firmware hackable HTs are hawt, in particular the Quansheng UV-K5,K6.

    Tons of SDR receivers out there to explore, and many extremely exiting transceiver projects out there also. Just so much:

  17. qutebrowser

    A keyboard-driven, vim-like browser based on Python and Qt.

    Project mention: Qutebrowser: A keyboard-driven, Vim-like browser | news.ycombinator.com | 2024-12-08

    See https://github.com/qutebrowser/qutebrowser/issues/8389 - unfortunately there's a lot of stupid false-positives especially with PyInstaller (packaging a Python application into an .exe). Happens a few times a year, unfortunately there isn't much I can do other than submitting a report to Microsoft and hoping they'll react ¯\_(ツ)_/¯
