What is a cheatsheet? It’s a quick reference for a technology or a tool.
I will try to maintain this page with many links on visual cheatsheets.I’ll put here only the cheatsheets that are easy to print (PDF/SVG, no html) and which are clear enough (colors, schema…).
I have added some refcards from DZone. A refcard is not only a reference, it explains the technology and how to use it (it’s like a “Quick start”).
If you have more useful links, leave me a comment, I will then update this page

NOTE: I provide the link of the cheatsheet creator’s website and the direct link to the cheatsheet. I think it’s useful to see quickly the presentation of the cheatsheet, it’s the reason why the direct link is there. If you like the cheatsheet, I recommend you to go to the official website: an updated version may exist. Moreover, I think it’s a kind of respect for the author.

If you don’t find a free cheatsheet, you may have a look at SparkCharts: the quality of their papers seems pretty good and it is not so expensive 4$95.
I wanted to put this article as a page, because I will update it over the time. Wordpress has no comment system on pages, so to add a comment, please follow this link
