Project mention: STB: Single-file public domain libraries for C/C++ | news.ycombinator.com | 2024-01-06there's glad (https://github.com/Dav1dde/glad) which you can use as a single .c file + .h header that defines OpenGL stuff or a single header-only file. I use it on all of my OpenGL projects!
Project mention: Castle Engine – free and OS, x-platform, 2D/3D game engine using modern Pascal | news.ycombinator.com | 2024-02-18In the meantime the repository moved to: https://github.com/opensoldat/opensoldat
Project mention: What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented? | /r/rust | 2023-06-09I tried to rewrite Clipper2 in Rust. There's a C#, a Delphi and a C++ implementation, so how hard can it be?

Project mention: SQLite-based databases on the Postgres protocol? Yes we can | news.ycombinator.com | 2023-07-04Damn my dyslexia I read marmot and thought you meant this unrelated project https://github.com/synopse/mORMot
Project mention: Delphi 11 and C++Builder 11 Community Editions Released | news.ycombinator.com | 2023-04-27For those who are Delphi curious you can use the wonderful skia4delphi [1] with firemonkey which gives you high quality graphics for all fire monkey components. So you can use all the existing components and commercial components and they'll render perfectly. Once you start using it you'll realise how awful and painful web development is. Fire monkey is the component library that works across windows/Mac/iOS/Android, replaces the old VCL windows only library.

Project mention: Kapowarr (sonarr/radarr for Comics) is officially live! | /r/selfhosted | 2023-05-24
This article reads more like an ad for mORMot 2 than Pascal. I've been out of the Pascal game for a few years, so I had to look up mORMot 2.[0] Apparently Synopse are the maintainers of it.
The article basically compare their CSV/JSON serialising library to Go's standard CSV/JSON libraries. Looking at the Go code, it's pretty clear why it has memory issues, it reads all the lines into a single object (well, `[][]string`) immediately, rather than reading line for line (which takes advantage of the stream).
I am not sure how this is remarkable and impressive for Pascal. They talk about how you don't need to use the `try..finally..Free` routine all the time, but that's only if the object in question is an interface. Interfaces are somehow handled by a reference counter in Object Pascal, so you need to know how to operate on objects vs interfaces, because they act very different. Pascal is full of these quirks.

I'm attempting this on a Pixel 3. I'm going to try the instructions in the gcc-termux README.md
Project mention: What's the most lightweight alternative to paint that you know of? | /r/linuxquestions | 2023-05-25
I've tried RInno, electricShine, and the electron-starter-app project by COVAIL.
Project mention: Louis Rossmann: Autodesk turns lifetime licenses into subscriptions [video] | news.ycombinator.com | 2023-07-01There is also a new competitor written in Lazarus/FPC - ZCAD[1]. Looks barebones for now, but nevertheless interesting.

Project mention: What library do TStreamWriter use in Lazarus(Free Pascal) used ? | /r/freepascal | 2023-05-02I see there is a TStreamWriter in PasDoc sources in PasDoc_StreamUtils https://github.com/pasdoc/pasdoc/blob/699c994ff2cf17ae6a876667e129bdb6698f3817/source/component/PasDoc_StreamUtils.pas but I'm not sure if this is a compatible reinterpretation of Delphi's TStreamWriter or something unrelated.
