This does NOT work on Raspberry Pi 2!

Obtain a 8GB (or bigger) SD Card
Download disk image from http://janos.io/builds/fxos-pi-gpio.img.zip and unzip
Put SD card in your computer
Find out where your SD card is mounted (BE REALLY SURE ITS THE RIGHT DEVICE, IT WILL BE WIPED COMPLETELY!!!), f.e. /dev/disk5 on OSX
On Linux, run: sudo dd bs=4M if=fxos-pi-gpio.img of=/path/to/your/disk
On OSX, run: sudo dd bs=4m if=fxos-pi-gpio.img of=/dev/rdisk5 (do rdisk, not disk here!)
When it's done put it in your Pi and start up
The demo's are wired like this: yellow LED on GPIO2, red LED on GPIO3, button (wire it as pulldown) on GPIO26.

ES6 Defaults / Overrides Pattern

Combine default parameters and destructuring for a compact version of the defaults / overrides pattern.

function foo ({
    bar = 'no',
    baz = 'works!'
  } = {}) {

CSS Layout Debugger

A tweet-sized debugger for visualizing your CSS layouts. Outlines every DOM element on your page a random (valid) CSS hex color.

One-line version to paste in your DevTools

Use $$ if your browser aliases it:
