I always have the Test Heuristics Cheat Sheet put together by Elisabeth Hendrickson, Dale Hemery and others to hand.

This is not language specific, but it's a great tool for test driven development and unit testing when thinking about missing functionality and how to make your code more robust.

This Encapsulation Hierarchy Table of design patterns cheat sheet is pretty useful:

It's not downloadable yet (I'm working on it), but I think a lot of web developers may have found the Ultimate IE6 Cheatsheet that I wrote useful.

Thankfully, it's becoming less useful with each passing month. We're dropping IE6 support on our next redesign since our demographics allow for it. But it's there if you need it.

I'm weird - I don't like "cheat sheets" made by other people...and my "cheat sheets" are just bits of code from my other code.

eg. connecting to a DB, I copy/paste. Or, some strange JQuery -- same thing.

Sure, originally I had to look it up, but once I add it to my "cheat sheet" organized how my brain wants things set up, it's a snap to find things.

So, imo, the "best" cheat sheet is one you make yourself. Personalized.

I think these are snippets not so much a cheat sheet. –  Chris Sep 16 '10 at 14:06

I really dig the cheat Ruby gem. Instant command-line access to an incredible variety of cheat sheets right at your fingertips. From Apache Regex to ZSH, and pert' near everything in between, and if you don't see one, create your own.

That really depends on the language/tool. Googling "[x] cheatsheet" where [x] is rails, regex, c#, etc works for me pretty well.
