This was really nicely done and a really good initiative. I got in to software development by teaching myself Python (badly) and PHP (badly), and it's probably quicker to list the things I do know than the cavernous gaps in my knowledge. For most software development jobs you can get by without knowing this stuff but it's great there are things like this to clearly explain fundamentals that are either assumed knowledge or communicated in (to an outsider) gatekeeping levels of dense terminology.
