Sticky notes and cheat sheets

Even though I am a very strong proponent of a paper-free workflow, I keep a number of physical sticky notes and cheatsheets around my desk at work. These are usually quick reminders of useful things I use infrequently.

Useful commands

Git

git diff --color-words=.

Highlight changed characters, instead of whole lines

git pull --rebase

Create MediaWiki Table from csv

This one isn't on a sticky note yet, but I wanted to record it somewhere. I'm constantly using Tables Generator when working on the wiki, but who knows where it's sending my data. Requires python-tabulate

python -m tabulate -1 -f mediawiki /path/to/input/file | tr -s '[:blank:]' | sed 's/ \([|!]\)/\n\1/g' | sed 's/\([|!]\)\+/\1/g'
