For the past seven years I have been writing annual year-in-review articles for the AMD and NVIDIA Linux graphics drivers. Much progress has been made in recent years for bettering the OpenGL Linux support from these leading closed-source graphics drivers and this year is no exception. Up today is a recap of this year's AMD Catalyst graphics driver releases plus benchmarks of this year's driver releases going back to Catalyst 11.12.

Great intro by guru Juliet Kemp-- With Android phones and tablets making their way into more and more pockets and bags, dipping a toe into Android coding is becoming more popular too. And it's a great platform to code for -- the API is largely well-documented and easy to use, and it's just fun to write something that you can run on your own phone. You don't even need a phone at first, because you can write and test code in an emulator on your Linux PC.

Look at the founders of any Internet startup, and you're almost certain to find an open source expert among them. Take Google, the biggest Internet success story of them all. Co-founders Larry Page and Sergey Brin built and ran their brand-new web indexing tool on servers running the open source operating system Linux—and still do, 13 years and several billion dollars in profits later. Pick an Internet startup—Facebook, Zynga, Groupon—and chances are you'll find open source software running on its servers (and an open source-savvy founder in the boardroom).

When talking about open source, many people's first thought is the GNU General Public License (GPL). While the software world has been revolutionised by GPL, the hardware world has seen little change. 

The first beta release of Mageia 3 Linux is now available...

This isn't a final decision by the USPTO. Apple will get to respond before any patents are truly killed off, and reexams are generally a long, dragged-out process. However, it is notable that all three of the utility patents Apple used to win its case are now having their validity seriously questioned.

Intellectual Ventures is at it again -- playing the "oh, little innocent us? we're not doing anything that should really concern anyone" card in the press. Wired is running an op-ed by Raymond Hegarty, IV's "VP Of Global Licensing in Europe." He's a long term patent maximalist... and it shows. The article is entitled: Intellectual Ventures: Why the Patent System Needs Aggregators Like Us, which should give you an idea of the fanciful rewriting of history you're about to read.

Many programming languages include libraries to do more complicated math. You can do statistics, numerical analysis or handle big numbers. One topic many programming languages have difficulty with is symbolic math. If you use Python though, you have access to sympy, the symbolic math library. Sympy is under constant development, and it's aiming to be a full-featured computer algebra system (CAS). It also is written completely in Python, so you won't need to install any extra requirements. You can download a source tarball or a git repository if you want the latest and greatest. Most distributions also provide a package for sympy for those of you less concerned about being bleeding-edge. Once it is installed, you will be able to access the sympy library in two ways. You can access it like any other library with the import statement. But, sympy also provides a binary called isympy that is modeled after ipython.
