Over the last few years I have had a dream of converting an old broken radio into a bluetooth enabled system.
So far I have purchased:
I have now started to put all of these parts together. Right now it has just been cobbled together on the kitchen table. It will eventually need to be moved into the Old radio case.
Items that still need to be selected include a small set of speakers and possibly some switches.
To put it all together I had to do a little bit of soldering.
I am starting a new project, I want to restore an old Radio, with new Hi-tech – low cost guts.
The plan is to find an old Radio on craig’s list, put in Raspberry Pi Bluetooth audio, and some new speakers.

If you like me want to run Mathmatica, now available on the Raspberry Pi, but you don’t have your Pi connected to a monitor, you can try this:
/opt/Wolfram/WolframEngine/10.0/Executables/math In[1]:= Print["Hello World"] Hello World
Then of course, you can add this to your path:
export PATH=$PATH:/opt/Wolfram/WolframEngine/10.0/Executables

Pig is a Map/Reduce Scripting language maintained by Apache Software Foundation. Pig takes scripts written in PigLatin and converts them to Hadoop Jobs. http://pig.apache.org/
As of the release of Cassandra 1.2.8, you can now read/LOAD and write/STORE with PIG to Cassandra CQL3 Tables. It has been possible to use the native Cassandra structure, but this was limiting, if you wanted to use CQL3 anywhere in your environment.
