zu == Unzipper (in the tradition of `uz`, but better). Works for .tgz, .xz, .zip, .deb, .rpm — you name it. (Literally. If you find an archive that it doesn't open, let me know about it and I'll add that.) If you have an archive sitting there of format `xyz`, then `zu foo.xyz` should take care ...

I talked about ((<"Goodbye fat gem"|URL:https://rubykaigi.org/2020/presentations/ktou.html>)) at RubyKaigi Takeout 2020. Fat gem is a gem that includes pre-built binaries. Extension libraries can assume that users have build environment with Ruby 2.4 or later. So gems don't need to bundle pre-bui...

The Ruby 1.8 Enumerable.sort_by method was stable, in that items with matching conditions were preserved in the same order. That's not the case in Ruby 1.9. Some of my code depended on this behavior, and I'm sure I'm not the only one. So here's a stable_sort_by method that preserves th...
