tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

start new:

tmux

start new with session name:

tmux new -s myname

Asynchronous programming can be tricky for beginners, therefore I think it's useful to iron some basic concepts to avoid common pitfalls.

For an explanation about generic asynchronous programming, I recommend you one of the [many][2] [resources][3] [online][4].

I will focus on solely on asynchronous programming in [Tornado][1]. From Tornado's homepage:

	var s = ''
	var result = ''

	var step = async (x, y, last) => {
	const response = await fetch(`/step?s=${s}&x=${x}&y=${y}`)
	const json = await response.json()
	const adjacent = json.adjacent.filter(
	item => JSON.stringify(item) !== JSON.stringify(last)
	)
	if (json.end) {

	class JsonEncodedDict(sqlalchemy.TypeDecorator):
	"""Enables JSON storage by encoding and decoding on the fly."""
	impl = sqlalchemy.VARCHAR

	def process_bind_param(self, value, dialect):
	if value is not None:
	value = json.dumps(value)
	return value

	def process_result_value(self, value, dialect):

	#this script can never fail
	#Usage: put this line into your config.fish
	# source $HOME/.config/fish/ssh_agent_start.fish && start_agent

	setenv SSH_ENV $HOME/.ssh/environment


	function __setup_env
	if [ -f $SSH_ENV ]
	. $SSH_ENV > /dev/null

	A Markdown/MultiMarkdown/Pandoc HTML output CSS stylesheet

	Revised: 21 Feb 2012

	General style is clean, with minimal re-definition of the defaults or
	overrides of user font settings. The body text and header styles are
	left alone except title, author and date classes are centered. A Pandoc TOC
