Markdown and reStructuredText

GitHub supports several lightweight markup languages for documentation; the most popular ones (generally, not just at GitHub) are Markdown and reStructuredText. Markdown is sometimes considered easier to use, and is often preferred when the purpose is simply to generate HTML. On the other hand, reStructuredText is more extensible and powerful, with native support (not just embedded HTML) for tables, as well as things like automatic generation of tables of contents.

Raspberry Pi, WiFi and motion sensors

My notes on setting up a Raspberry Pi with an Edimax EW-7811UN WiFi Dongle and motion sensors.

We intend to use a few Raspberry Pis around the office, in order to find out if certain rooms are beeing used or not. For this, we need to get WiFi and a motion sensor working.
