Rosetta Code's the one I was thinking of, but I really dislike their structure - I never want to see how to do something in
dozens of languages, almost all of which aren't relevant to me.
What I would love to see is:
1) select language you want to learn
2) select languages you already know
3) you get a cheatsheet like the OP that goes through all the basics (and maybe even more detailed), and all the code samples are changeable ala MSDN where you click "C#" or "VB.NET" or whatever to see the code in that language: http://msdn.microsoft.com/en-us/library/system.drawing.bitma...
