Cheatsheets

This is cool - a collection of more than 30 different developer cheat sheets pulled together by Pete Freitag on topics as diverse as web technology, databases, version control and more.

To quote the page:

Lets face it, unless you have a photographic memory, no developer can remember all the different functions, options, tags, etc. that exist. Documentation can be cumbersome at times, that’s why I like cheat sheets. They are quick references that feature the most commonly forgotten things on a specific topic. You can print them out and hang them on your wall, or just keep them handy in your bookmarks for quick reference.
