This server may be slow an unreliable, and offline for extended periods of time,
it is recommended to use the codeberg.org/maandree
instead, and only use this server for release metadata.

* marks stable projects that are not completely finished but are not actively being worked on,
if you want something to do, take a look at them, with a few exceptions, they shouldn't be
too difficult, but at the same they shouldn't be too trivial.
Tips
Philosophy
C mastery
Critique of C++
Until you've seen a real assembly project, you haven't seen clean code.
Until you've seen a real C++ project, you haven't seen nightmare code.
That is the cost of abstraction.
Bad UX ideas
