Learn X in Y minutes
In the past we had “flash cards” to memorize and review materials. This site Learn X in Y minutes has one-page reminders that can be used to re-learn material or get some idea of what the subject is about.
For example I wrote a series of 4 posts titled Do yourself a favor: learn Markdown. By going to the XY site the reader will find a whole page with easy to understand examples of markdown: learnxinyminutes.com/docs/markdown with code that is easy to copy paste.
Not all pages are easy to follow if the reader does not know the subject. But it is clearly a quick way to access commands not easily memorized. One that I know I ‘ll use is the page for the version-control program git.
Many pages are available as translation in various languages: Spanish, German, French, Portuguese, Russian, Italian, Chinese… But not all pages are available as translation for all languages.
Overall this is a “neat” web site to quickly remind oneself of things previously known but forgotten or hard to remember.
