Simple Raspberry Pi GPIO example

Introduction

This is a dead-simple way to test that GPIO on the Raspberry Pi is working. I have an SKPang Raspberry Pi starter kit A. But all you need is

  • A Raspberry Pi.
  • An LED.
  • A button.
  • A resistor, approximately 270Ω.
  • Some way to connect these to each other and the GPIO pins.

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
