Google's Code Jam Qualification Round for 2014 is planned on 11 April. In the link below they specify that programming in any programming languages is accepted as long as there is a free version. So they say , Maple and Mathematica are excluded but they accept MATLAB, because of open-source versions like Octave!https://code.google.com/codejam/faq.html
Now with the Raspberry Pi free version (Wolfram Language) I think they should rethink that. I assume they can afford buying a full Mathematica Version to test all the sent code, right? (it is Google guys come on) Just a thought - it is petty to leave out one of the best programming languages. I would appreciate any feedback concerning future plans for this matter.
