Hi HN,
I wanted to share decomp.dev - a nifty site that tracks video game decompilation efforts, mostly games from from the early 2000s.
I find it very fun to look at older c/c++ code from video games I used play, but also how the code was designed around very limited hardware requirements.
I come from a TS/Python background so a lot of the techniques are alien to me (for example, using bitflags everywhere to save memory).
That example is probably trivial to the more experienced devs here, but it's still interesting.
All source code is written from scratch, done with matching decompilation efforts to slowly compile the code into the original binary, by a team of very talented volunteers.
