 ### About Scratch
 
+https://en.wikipedia.org/wiki/Scratch_(programming_language)

 Scratch is not "children's programming language", while it looks like it is. Scratch prevents making syntax errors in code. With scratch, my friend teenager nerd boy made game, where at beginning of game it generates random levels. It's very advanced.
 
 I did see somewhere some paid software where it's possible to make sheduled tasks to Jira with Scratch like interface.
