FFMPEG cheatsheet

Twitter only works with videos with AAC audio, YUV 4:2:0 pixel format and an aspect ratio between 1:3 and 3:1, according to their developer docs

ffmpeg -i input_video.mp4 -c:a aac -c:v libx264 -filter:v "format=yuv420p" output_video.mp4

GNOME is nice, but it comes with a lot of packages by default. You may wish to install a more lightweight version.

Install nvim, urxvt and zsh:

Arch:

# pacman -S neovim rxvt-unicode zsh wl-clipboard

	#!/bin/bash
	# /etc/cron.d/mysql_watch_online

	# Test the database connection and restart on failure
	mysql -e '\q'

	if [ $? != 0 ]; then
	echo `systemctl status mysql` \| mail -s "MySQL Databse experience issues \| `hostname`" [email protected]
	systemctl restart mysql
	fi

	SUBSYSTEM=="i2c-dev", ACTION=="add",\
	ATTR{name}=="NVIDIA i2c adapter*",\
	TAG+="ddcci",\
	TAG+="systemd",\
	ENV{SYSTEMD_WANTS}+="ddcci@$kernel.service"

	# For some reason giving group permission to read/write MATLAB install dir isn't enough
	# Do this to get the command then run as rot (sudo)
	ps -eo cmd \| grep AddOnInstaller \| head -n 1

	Print
	scrot -s ~/Pictures/%d-%m-%y_%h-%m-%T_$wx$h_scrot.png -e 'xclip -selection clipboard -target image/png -i $f'
