Don’t know about you, but if you can’t find the manual to look up Appendix C (have you ever noticed how nearly everytime you need tech info, it’s in Appendix C) a cheat sheet is the next best thing.
Over at Tech Cheat Sheets is a collection of the best cheat sheets and quick reference guides you are likely to find on the web. Arranged by tags, you can subscribe to a feed for only the tags you want to monitor. So if there’s a specific technology topic you’re looking for, such as Ruby,you can subscribe to that tag with your feed reader and have all the Ruby cheat sheets delivered right to you as they are added to the site.
Very handy.
