Not having a great time with the kernal's OOM¹⁾ Killer at the moment; it's not doing the job I expected it to, and I'm getting freezes when I get down to about 1GB of RAM.

There are three userspace solutions I've read about:

• The early oom daemon | rfjakob/earlyoom earlyoom
• nohang | hakavlad/nohang nohang-git
• oomd | facebookincubator/oomd oomd oomd-git

The main memory hog is me having a lot of tabs open in Firefox, which in combination with electron garbage and other hoggy things like a second web browser and Thunderbird 'causes most of the problems. Sometimes I even forget I have all those things up and start playing a game :/

• OOM Killer on the Linux-mm²⁾ wiki.
• Surviving the Linux OOM Killer

See CUPS

I forget how to do shit a lot.

You can pause activity in the terminal with Ctrl+s, and resume again with Ctrl+q, which I find handy sometimes when I'm doing updates.

If you think of it beforehand you can pipe output to less or more or send it to a file, but I never remember.

For me, mmv has the easiest syntax to remember. You'll probably have to install it.

mmv [options] [from] [to]

You use #[number] in your [to] to represent wildcards in your [from].

Rename all files Treme SxxExx.mp4 to SxxExx.mp4
mmv “Treme *” “#1”
