What? Did you even look through at how comprehensive the list of APIs they have online here is? I'm a full-time developer . No way I'm going to waste my time making a cheat-sheet for functions I may only write a few calls to when I could be doing productive coding. There's just too many APIs I need to use.
For something I love and want to use all the time, like Python, I'll make my own cheat sheet. For something like MySql, where I have to kick myself to pay attention every thirty seconds, there's no way I'm doing my own cheat sheet. I can barely bring myself to do the actual work.
So I take it you must be used to reading documentation and picking up new languages pretty quickly? If you must keep going to the documentation to remember a function, copy it out. I don't see how needing to dig through out of order lists is any more useful than digging through long winded documentation. The point of a cheat sheet is not just remembering the thing, but finding it quickly.
This is an awesome resource.
