I know there's not a lot on there (only 8) but can I say thank you for actually having real cheat sheets? I like cheat sheets, I print them and laminate them and keep them around my desk. There are waaaaay too many sites trying to pawn off full references as a cheat sheet. A good cheat sheet should be 1 (maybe 2) pages long and in a print friendly format.
The GitHub git cheatsheet link does not work for me, Firefox, Chrome or Chromium. This link would seem to get you to the best version for you <a href="https://github.github.com/training-kit/" rel="nofollow">https://github.github.com/training-kit/</a>
