UPDATE 3: I did find the source of that regular expression card at Gordon McKinney's Pro IT Blog. Well, it's not a LaTeX source, but it's at least in letter format.
UPDATE 2: I found another good list of quick reference cards at the plantOzh blog. It includes a a regexp card, Perl 5 booklet, and CSS cards (1.0, 2.0). Yes, these cards are archived at the blog, so all of the commentary below still applies.
UPDATE 1: It's also annoying when someone simply archives existing quick reference cards because sometimes those archives use A4 paper. If these were linked to their origins, the source code (perhaps LaTeX) might be available, making a conversion to letter paper easy.
Lately, I have been quick reference happy [1, 2, 3, 4]. I cannot explain why, but I suddenly want to surround myself with quick references.
I think I found a great new quick reference resource. It's The Quick Reference Site, which features quick reference cards, e-books, and other papers and tutorials. From the site:
Throughout the years I have collected a huge pile of documents that deal with almost every aspect of software development. The purpose of this site is to centralize this information and to make it available to everyone who may need it or shares my passion on this subject. There are still a lot of documents in my "archive" that I like to share with you all.As far as I can tell so far, the author archives quick references that he has found over time and links us, the readers, to those archives. The advantage of this is that it minimizes the chances of broken links. The disadvantage is that the archives may not be the most recent versions. Additionally, if this site ever goes down and our bookmarks point there, those bookmarks will be broken.
At the moment this site represents only a fraction of what I want to provide, so a lot of work still needs to be done. As a result, you should consider this site as a work in progress. I'll try to keep you updated on the most challenging, powerful and continuously evolving software technologies of the moment. I hope that especially Java and C++ fanatics (like myself) will find some valuable information over here.
Some quick reference cards that I want to point out (if you go to his list, you can also read descriptions of these programs):
