I've completed this entire course, and in my opinion, it's the best resource out there on this topic (even better than nand2tetris or ben eater). Sadly, given that it's paid, I'd be extremely surprised to see it reach the front page of HN, regardless of how good it is.
It's so interesting how I feel the same way about where I live now... and even more interesting that every time I visit the US, people seem happier there than anywhere I've been before.
That reminds me of an old comic where a guy picks a milk carton from the grocery store shelf and reads in the box: "Now with 0.01% less semen." and he does not know if he's happy or sad about it.
I think it's worth mentioning Gustavo Pezzi's lectures at pikuma.com. The one on "Digital Electronics" and the one on "Interpreters & Compilers" really helped me.
The first time I saw Wren was as an option for programming inside TIC-80. It caught my attention. I recently saw it again being mentioned by Gustavo (from pikuma.com) in his compilers course. Neat language and the VM code in C is quite easy to understand.
gustavo!!! your website was the first thing i thought of as i was reading this blog post. im a huge fan of your teaching style. thank you for everything you do! :-]
Writing that programmers that use Euler instead of RK4 are "bloddy idiots" might work well to get some laughs in a blog post when the author is trying to stress how RK4 is more accurate and stable than the alternative, but there are cases where real-time applications (especially on older machines and older consoles) could not afford the overhead of RK4 and Euler was gave good-enough for what they needed.
