I don’t have any blogs that I specifically check for new posts but these are blogs that I’ve enjoyed several posts from in the past:
Julia Evan’s Blog: It’s just a joy to see how curious Julia is about learning about and understanding computers and programming. Usually also very approachable, clear writing. You may also want to check out her Zines.
Joel Spolsky’s blog: Another founder of Stackoverflow, if you scroll down you can see a list with the Top 10 most clicked posts. The Joel Test was really important at the time to force companies to level up their development processes.
