For those of you who use and love subversion (svn) as much as I do you will be happy to know that David Child from Added Bytes (formally know as I Love Jack Daniels until certain legal misgivings) has released a Subversion specific cheetsheat, his first new one is almost a year.
I’d definately check out his other cheatsheets while you are on the site, they are an excellent resource for many different languages and common tasks.
Also for any developers interested in the discussion going on about the cheatsheets Dave has created a google group specifically for cheatsheets. Awesome.
