Raspberry Pi GPU Driver Turns Out To Be Crap

While it looked hopeful at first with today's announcement of a fully open-source graphics stack for the Broadcom VideoCore found in the popular Raspberry Pi development board, upon closer examination it's actually not that good.

Another ARM Video Decoder Being Reverse-Engineered

While the binary wall has yet to fall with ARM SoC vendors in terms of providing open-source drivers -- namely when it comes to the graphics / multimedia blocks -- there's many active community projects for reverse-engineering these ARM blocks to provide open-source support. Here's another project that's being done for cracking the video decoder on a popular Chinese ARM SoC.

MacBook Pro - Ubuntu Linux: 21 Watts, OS X: 9 Watts

Earlier today I published the long-awaited benchmarks of OS X 10.8 Mountain Lion vs. Ubuntu 12.04/12.10. The benchmarks showed strengths and weaknesses of both operating systems, resulting in the the usual spectrum of comments from Phoronix readers. Here now are the power consumption results when comparing OS X and Ubuntu Linux on Apple hardware.

2012 MacBook Air Isn't Trouble-Free On Linux

While lately I've been busy with trying out the Retina MacBook Pro under Linux, which has been a big problem and I'm not recommending the rMBP for Linux users at this time (more details soon), it looks like the new MacBook Air might also have some Linux woes. Outside of Apple, the Sony Vaio Z Ivy Bridge laptop also has some Linux problems of its own.
