I follow regularly these people, these are mostly slow-going blogs or websites:
1. Fabrice Bellard: https://bellard.org/ This is not really a blog, but a traditional website with links to the work of its author (who is probably one of the top programmers ever). It updates rarely, but when it does, it is to expose yet another monumental piece of computing work that will blow your universe.
3. Uriel l'Étranger: http://cat-v.org/ The only self-described "philosopher of software" that I have ever seen. His website is of course not updated anymore, but you can re-read it many times and always learn something new.

2. Linus Akesson: https://www.linusakesson.net/ He's always onto some funny crazy things: obfuscated programming, underhanded programming, c64 emulation, chiptunes...

4. Ted Unangst: https://flak.tedunangst.com/ Nice to follow some cool news about openbsd development
5. Andy Chu: http://www.oilshell.org/blog/ Who has embarked in an amazing quest to turn the unix shell into a cleaner tool
6. Jens Gustedt: https://gustedt.wordpress.com/ If you really want to be up to date about the evolution of the C language
