Welcome!

For feedback or suggestions, please send a tweet (@dideler). Gist comments don't notify me. Pull requests aren't possible with gists (yet), so I don't recommend forking because then I can't easily get the change.

Starring this gist will give me an idea of how many people consider this list useful.

TODO

• Organize resources into sections
• More detailed sections (perhaps sections & subsections)

Attention: if you attempt to fork this gist, github will think that you are a spammer and you will have to confirm that you are human with them. Apparantly there are too many links in this list. Also I update it rather frequently (see revisions on the left), so it's probably wise to not fork it anyway.

ruby-1.9.3-p429 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p429 with the railsexpress patchsets from https://github.com/skaes/rvm-patchsets

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
