A build/make system for latex (akin to e.g. latexmk) which tries to be intelligent about pulling in dependencies, running the right amount of build generations and so on. Seems pretty user friendly in that it tries to automate away most of the LaTeX tedium!

"Text-based contact management software."

Plaintext addressbook - akin to khard or abook. Gives you a TUI which is nice, and can be integrated well with mutt. Uses vCard (3.0) so it can be made to work with the wonderful vdirsyncer as well.

Has adblock built in and comes with a small extensions store which is nice.

If you have a script that needs to keep up a single infinite pipeline but want to use sed (or grep) with it, simply use:

sed -u <mysedstuff> to flush the pipes more often (usually means after every line)

You can also use a command called stdbuf, see here https://unix.stackexchange.com/a/25378 in case you need it for other programs which do not support such a flushing mode.

A wonderful little one-liner to grab all VARIABLE=CONTENT lines from an environment file and automatically add them to your current environment.

export $(cat /your/file/env | xargs)

But there are variations for potential spaces in the var content, only setting them (eval) for a single command and automatically unsetting variables again,
