BigData meet Raspberry Pi

The Raspberry Pi is a very neat little machine - I bootstrapped it with Soft-Float Debian "Wheezy" so I can run Java Embedded on it - I download and install ejre-7u10-fcs-b18-linux-arm-vfp-client_headless-28_nov_2012.tar, and now can run java programs on the Pi. Wrote the ubiquitous "Hello World" to make sure it works (I should not have doubted the write once run anywhere motto) and jumped...

BigData: Kernel Density Analysis on Hadoop MapReduce

The storage of BigData has been democratized by Hadoop. And with that, rather than bringing the data to the program for analysis, we send the program to the data. That twist comes with a challenge to take existing serial algorithms and parallelizing them. This post is about such a process. I want to perform a Kernel Density analysis on billions of records loaded into HDFS. The data is fairly simple;...
