I play around with code a lot, this is where some of those experiments end up.
These are experiments, often in some state of flux. I might try something that I am thinking of doing a talk about, or do some "scratchpad" work while doing a course. Or I'm just high on sugar and crafting bugs. Anything goes.
Also, quite a lot of this is part of me mentoring and/or teaching someone something. I find that making people pull code from Git helps them learn some basic skills in the process.
Some of the code here is not meant to compile or run, because I was testing something specific and needed to create a scenario. So don't be alarmed if there are errors, it might be intentional. Only, you'll never know now, will you?
Seriously. Especially not on a mobile device. Terrible Idea.
