A LDR (light dependent resistor) is glued on the on/off led of the coffeemachine. When the coffeemachine is switched on the led turns on, the ldr detects this light. This LDR is connected to an Arduino microcontroller, Processing reads the value from the Arduino using Firmata and Processing sends this to a php file which will send it to Twitter.

This project involves creating a Persistence Of Vision (POV) device for mounting on a bike wheel. There are a few of these devices already on the market (and we've bought a couple to experiment with); this project differs in that it combines a basic bike meter with the POV readout. The device will display speed and total distance travelled. Unlike standard bike computers, this information isn't displayed for the cyclist but broadcast to other people in the street. By making this information public we give the cyclist's activities greater 'visibility' within the urban environment.

This document summarizes the initial research for adding distributed version control as an option for Google Code. Based on popularity, two distributed version control systems were considered: Git and Mercurial. This document describes the features of the two systems, and provides an overview of the work required to integrate them with Google Code.

Introducing Phusion Passenger™

Phusion Passenger™ — a.k.a. mod_rails or mod_rack — makes deployment of Ruby web applications, such as those built on the revolutionary Ruby on Rails web framework, a breeze. It follows the usual Ruby on Rails conventions, such as “Don’t-Repeat-Yourself”.
