Generating Recommendations with MapReduce and Scalding
Scalding is an in-house MapReduce framework that Twitter recently open-sourced. Like Pig , it provides an abstraction on top of MapReduce that makes it easy to write big data jobs in a syntax that's simple and concise. Unlike Pig, Scalding is written in pure Scala -- which means all the power of Scala and the JVM is already built-in. No more UDFs, folks! At Twitter, our mission is to instantly connect people everywhere to what's most meaningful to them.
1. Overview MRPT implements a common C++ interface to Xbox Kinect, a new RGB+D sensor with an immense potential in mobile robotics. The implementation offers the user only one unified interface. Behind the scenes, MRPT uses one of these libraries to actually access the sensor:

Updated January 11th 2013 : Watch my BACON talk on this project on vimeo . Updated January 2nd 2012 : the source code is now open source and available on github. Recently, I have been refreshing my knowledge of Machine Learning by taking Andrew Ng 's excellent Stanford Machine Learning course online. The lecture module on Neural Networks ends with an intriging motivating video of the ALVINN autonomous car driving itself along normal roads at CMU in the mid 90s. I was inspired by this video to see what I could build myself over the course of a weekend.
