Top 10 C++ Source Projects

OpenRGB
Open source RGB lighting control that doesn't depend on manufacturer software. Supports Windows, Linux, MacOS. Mirror of https://gitlab.com/CalcProgrammer1/OpenRGB. Releases can be found on GitLab.
Project mention: Writing a basic Linux device driver when you know nothing about Linux drivers | news.ycombinator.com | 2025-06-26I think they wrote the code more for the challenge of it than anything else. The final code doesn't seem to do more than the bare basics (which is probably enough for the author).
Plus, to port this to OpenRGB, you'd need to rewrite the code into C++ (ugly, old C-inspired C++, at that: https://github.com/CalcProgrammer1/OpenRGB/blob/master/CONTR...) which would take most of the joy out of it for me at least.

What are the flaws of this game?

So we all know TF2 is barely held together in code right? And they added stuff to make it easy for devolopers to make better maps and easier code and stuff. I dunno I am not a nerd- Anyway. So,what if...they are trying to fix TF2's spagetti code so that they can make other updates easier?
