I am looking for old-school (html only, mininalist design) programming blogs, that are mainly focused on math, algorithms or systems programming. I also don’t mind a few rants, movies or books reviews, but the content should be mainly technical.

For example: nullprogram.com would qualify perfectly.

If not, a list, maybe some links?

I prefer quality over quantity, you know the type of content that usually gets upvoted on hn, without the corporate bullshit or angel investment stuff.
