Cheat Sheet Roundup - Over 30 Cheatsheets for developers

September 01, 2005

Lets face it, unless you have a photographic memory, no developer can remember all the different functions, options, tags, etc. that exist. Documentation can be cumbersome at times, thats why I like cheat sheets. They are quick references that feature the most commonly forgotten things on a specific topic. You can print them out and hang them on your wall, or just keep them handy in your bookmarks for quick reference.

I have rounded up over 30 cheatsheets that developers might find useful.

Web Development Cheat Sheets

Databases / SQL Cheat Sheets

Language Cheat Sheets

Version Control Cheat Sheets


Commercially Printed CheatSheets

Am I missing any good ones? Feel free to post any others in the comments.

The UMBC Semantic Web Reference Card is a handy "cheat sheet" for semantic web developers and programmers. It can be printed double sided on one sheet of paper and tri-folded.
