Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

plain ascii
ansi escape codes (16 colour codes with bold/italic and background)
256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
24bit true colour ("888" colours (aka 16 milion))

printf "\x1b[${bg};2;${red};${green};${blue}m\n"

Using diff: red/green monospaced text

+ Green.Like all Byzantine agreement protocols, SCP makes no assumptions about the rational behavior of attackers.
- Red. Like all Byzantine agreement protocols, SCP makes no assumptions about the rational behavior of attackers.
Black. Like all Byzantine agreement protocols, SCP makes no assumptions about the rational behavior of attackers.

Using code comments: gray text

Regular Colors

Value	Color
\e[0;30m	Black
\e[0;31m	Red
\e[0;32m	Green
\e[0;33m	Yellow
\e[0;34m	Blue
\e[0;35m	Purple

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

UC Berkeley landmarks coordinates (longitude and latitude) in JSON format

The js script converts xml files from the UC Berkeley website's map.

These may be outdated. Run the script yourself to get the latest data.

I do not own this data. I am simply converting the data between formats.

	#!/bin/bash

	# tmux requires unrecognized OSC sequences to be wrapped with DCS tmux;
	# <sequence> ST, and for all ESCs in <sequence> to be replaced with ESC ESC. It
	# only accepts ESC backslash for ST. We use TERM instead of TMUX because TERM
	# gets passed through ssh.
	function print_osc() {
	if [[ $TERM == screen* ]] ; then
	printf "\033Ptmux;\033\033]"
	else

	while true
	do
	./run.sh &
	sleep 3600
	sudo pkill -INT python
	sleep 5
	done

	// Batch form filler to be used in the console
	formValues = [
	['foo','bar'],
	['bar','baz'],
	['baz','blah'],
	['blah','blahblah'],
	['wibble','wobble'],
	['flob','wubble'],
	]
