"Heroku: Up and Running" is a behind the scenes look at the inner workings and rationale behind the Heroku Platform as a Service (PaaS). The authors, both web developers currently working at Heroku, explain the architecture of Heroku and walk the reader through some of the pitfalls of getting a web application up and running on Heroku while pointing out clever features along the way.

"Distributed Network Data" is a beginner's guide to building a swarm of wirelessly-connected Arduino-powered "motes" or sensor nodes.
This book takes the reader step by step through the process of creating an Arduino based sensor node equipped with a combined temperature and humidity sensor, a motion sensor, and a microphone. This sensor "mote" is connected to a receiving computer via an XBee wireless module. On the receiving side, we connect a master XBee directly to a computer to receive data from one or more "motes", log it all to a text file and graph it with Processing or LabVIEW. Full Review >
