Blogs are significantly more up to date with most technical topics. Books focused on specific technologies by contrast go out of date as soon as they are published. For example: https://simonwillison.net/ is HN's favorite blog this year.

Evergreen computer science topics don't go out of date though. (example of evergreen: https://dataintensive.net/)

I have an RSS opml of about one thousand blogs that I follow. Actually a majority of them are RSS feeds of people who have posted here in hacker news.

I also like to try to read research papers every now and then. On weekends I'll print one out and sit with a french press and pen and read through it, and it's a nice time. (Today I'm reading "Fruit and vegetable intake and the risk of cardiovascular disease, total cancer and all cause mortality" by Aune et. al 2017)

Ive been reading a lot of docs and not gonna lie it can be interesting just reading how a matrix works exactly for 3 hours straight. Ive read an article about how chopsticks where made, just those random informations you will never need again lol

I read Chinese novels that launch a couple chapters per day.
