Patch most proud of

« What accomplishment you are most proud of » is a common question on job interview, but if the question was about a patch, pull request or contribution for a project?

My list in chronological order:

• https://github.com/ruby/ruby/pull/12

  At af83, I was working on some Intel architecture and custom OS for a French TV broadcast company, and we needed to compile our stack on the box. This is where I found this problem because I disabled sslv2 on openssl.

• https://github.com/jekyll/jekyll/pull/360

  At af83, we used jekyll for the devblog, and we discovered that issue because we used validate-website as CI testing before merging.

• https://github.com/preinheimer/xhprof/pull/52

  It was one of this thing you don't understand why its not working because your IP is on the white list, then you doubt about your network skills ... It was just a bug.

• https://github.com/Homebrew/homebrew/pull/31044

  It was really interesting work as new OSX user and new packaging system to discover.

• https://github.com/puma/puma/pull/697

  This one because it was difficult to reproduce. Puma have so many options and custom configuration that it took me some time. It's good, it's a regression test.
