There are a lot of lists of top programming languages, most of which are written by cheesy copywriters. IEEE's annual report seems more or less accurate, although their Embedded seems a bit weird (Python? For embedded? Really? What a waste of hardware). They just released their 2019 report.
For some reason, I type 'moo' a lot, unconciously. It's my default metasyntactic variable (along with 'apple' and 'banana'). I think it goes back to one of those 'intro to OO' things that uses farm animals as an example, that I read many years ago. Googling 'moo' lead me to this low-budget, NSFW slice of joy. This is all the good things that people used to say about punk rock but weren't actually true.
I've read before that before the internet, people would copy entire games from magazines in machine code, assembly, basic or a mix thereof. It turns out that most of these - having no commercial value nowadays - have been made free on archive.org. Take a look at this insane insert.
Speaking of low-level programming and retrocomputing, this short tutorial is not just a great introduction to 6502, but a good intro to assembly in general. I wish I had something like that instead of the spiderweby books I learned from.
