/g/entoomen taught me a lot about Linux too. The desktop and home server threads also have a lot of gold, people put a lot of effort into their systems. There are even Lisp generals. I remember people attempting the advent of code together and posting progress. There was one person who used a lot of Unicode in the source code.

Just yesterday I saw a rather interesting discussion about WD HDD internals and possible ways to figure out whether they are SMR drives. Shame this hack cut it short.

/tg/ had some seriously good chess players.

There's a board for everything. People see 4chan and think everything is /pol/. If anything, it's /a/. People have been arguing over which waifu is best girl for 20 years. 20 years.
