The main issue I had while using NixOS is that it has a small and somewhat broken set of packages. This is compounded by the very incomplete Nix documentation - its way too hard to create new packages.

I agree the documentation needs work. It can be a real exercise in institutional knowledge sometimes to piece things together. I'd love to help you package something new, or fix an existing package if you would like. The thing that kept me going is how easy it was to fix ... after learning the incantations.

I think the project as a whole would welcome suggestions on where to improve docs as well, and would _definitely_ appreciate some new docs being written. It is hard to do this once you're too familiar :(.

Quick question, the url https://nixos.org/nixos/download.html lists the same url for both 32 and 64bits iso, I wonder if these are multiarch images or just an error.

An error for sure, we're on it!

If you found out through gdb that your code compiled with -O0 was still somehow optimized by gcc, or if you found out that your gcc did not optimize your code aggressively enough although you gave it -Ofast, check out this issue [0].

Yeah. The devs believed it was okay to make gcc -O2 by default and impossible to override from the command line you gave to gcc.

If you encountered this issue I hope google could quickly bring you to that issue on github. Good luck and don't waste hours to figure out why.
