The perfect book for the hobbyist or the instructor that would like to build a robot using the Raspberry Pi. Run from Windows or Debian-Linux over a WiFi connection. Learn the use of GPIO, how to remotely control your Pi and the Pi Camera. The complete Python version 3.2 source code included along with wiring diagrams. Run your robot without a monitor, keyboard or mouse on the Pi.
 
Instant Flask Web Development lets you set up your development environment and learn how Flask handles web requests, then shows you how to build a functional data-driven web application that is ready to publish, by adding one layer at a time. When working with Flask, you can work with Python and utilize its best tools for the job. The book will help you build the layers of a simple application: URL routes with Flask, a database with SQLAlchemy, form validation with WTForms, user authentication and sessions, page layout with Twitter Bootstrap, and browser code with jQuery.

Python Jobs of the Week

We're looking for an excellent Python developer to be part of a four-strong team of experienced Pythonistas, working on a challenging, 'big data' app. The app uses technologies like elasticsearch, Django, Redis, Postgresql, Circus for managing multiple processes and SaltStack for provisioning multiple servers in Amazon's EC2. Experience in any of those is a plus, but writing good, robust, scalable, parallelisable software is what we're really after. 
 
We are looking for a developer to join our team building behavioural analysis products. You know the ropes already - you're completely happy working with python in a console (and you probably have an opinion on Vim) and you're definitely familiar with the more esoteric commands in Git. Ideally you've been working with Django for a while and you know your way around the python web stack.
