Project mention: LVGL Kft switches to freemium; begins closing modules | news.ycombinator.com | 2026-03-06
LVGL has begun removing modules from trunk and closing them under licensing fees.
On GitHub, LVGL Kft accuse developers using the pre-closure MIT licensed XML module of IP theft: https://github.com/lvgl/lvgl/issues/9663#issuecomment-384163...
Have to read the commit history here: before last October the XML component was MIT licensed, then it was relicensed as proprietary, then removed, then someone appears to have forked an older version.

bgfx
Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library.
Project mention: Minecraft Java is switching from OpenGL to Vulkan | news.ycombinator.com | 2026-02-18 -
> There are frameworks and libraries that handle 100% of clipboard OS specifics
They're sufficient in many cases, but you'll still sometimes need the control of working with COM/etc. directly, and those libraries don't fully save you from platform-specific bugs (e.g: https://github.com/glfw/glfw/issues/2644).
> the app in question has no use for system clipboard in the first place
What do you expect to happen when you copy some text from an external editor into a text field?

Project mention: yazi: Rust Terminal File Manager with Image Preview — Alacritty Fix Included | dev.to | 2026-04-21
On macOS, Überzug++'s X11/Wayland backend is disabled at compile time, so it can't overlay images. yazi automatically falls back to Chafa, which renders images using Unicode block characters inside the terminal.

HandmadeMath
A simple math library for games and computer graphics. Compatible with both C and C++. Public domain and easy to modify.
sp_math.h is, as noted at the top of the file, a repackaging of https://github.com/HandmadeMath/HandmadeMath
It is not part of the core library. It is certainly not meant as a reference-level implementation of math functions. It's there so you can write an easing function for a game without pulling in libc. It seems like its existence has offended you. If that's the case...I'm sorry? At every possible point, I note as loudly as possible exactly what that library is. I found your tone extremely dismissive and disrespectful and I don't care to engage with that any more than I already have.

Project mention: rlsw – Raylib software OpenGL renderer in less than 5k LOC | news.ycombinator.com | 2025-10-21
Not sure what the line count is, but PortableGL is a software renderer for 3.x(ish):

Cool project, and fun to play with.

Project mention: Perfect Software – Software for an Audience of One | news.ycombinator.com | 2025-12-23
By the authors definition, I've been writing perfect software for over a decade.
It's never required LLMs. In fact, I think the idea that "LLMs allow us to write software for ourselves" borders on missing the point, for me at least. I write software for myself because I like the exploratory process .. figuring out how do do something such that it works with as little friction as possible from the side of the user; who is of course myself, in the future.
I like nitpicking the details, getting totally side-tracked on seemingly frivolous minutiae. Frequently enough, coming to the end of a month long yak-shave actually contributes meaningful insight to the problem at hand.
