For the past week now we have been extensively benchmarking AMD's new AM1 APUs with all the current models available to the public: the Sempron 2650 / 3850 and Athlon 5150 / 5350. All of our testing up to this point has been using an updated Linux kernel and Mesa for the open-source Linux graphics driver experience with these APU Radeon R3 Graphics. Today, we're looking at the performance of the open-source RadeonSI Gallium3D driver in multiple configurations compared to the proprietary Catalyst Linux driver.
For those that missed the news from this past weekend at PAX East 2014, a Linux game port of Star Citizen has been officially confirmed.
With Ubuntu 14.04 LTS due to be shipped this week, Canonical developers are already well at work on formulating their plans for the Ubuntu 14.10 release due out in October. Given Ubuntu's tablet/phone focus and convergence strategy, that will be the big aim of this post-LTS release.
For those users of Enlightenment out there, there's new stable release updates out today.

The first release candidate to the Linux 3.15 kernel is now available and it marks the close of the kernel merge window for about two months. Linux 3.15 is poised to be a very exciting kernel release.
It's been a busy past few days since AMD launched their "AM1" Socketed Kabini APUs. After the initial Athlon 5350 Linux review on launch-day, I did some tests involving a faster kernel and newer Mesa code along with some reference DDR3 memory scaling benchmarks for these APUs with Jaguar processor cores. Since then the Athlon 5150 and Sempron 3850/2650 APUs arrived. After a busy weekend of benchmarking, here's the initial Ubuntu Linux benchmarks of all four AMD AM1 APUs that are available at this time: the Sempron 2650, Sempron 3850, Athlon 5150, and Athlon 5350. With these four new AMD APUs are also a number of thermal and power consumption tests.
Version 1.5 of pass, the aptly named Unix standard password manager, has been released after about eighteen months of development.
An individual has been doing a lot of benchmarks recently from various lightweight window managers ranging from Openbox to Fvwm2 to Fluxbox with Compton and Awesome and Cairo-compmgr.
Sid Meier's next major game release in the Civilization franchise will see a native Linux game port.
The GCC 4.9 compiler that's about to be released has many improvements, including in the area of LTO (Link-Time Optimizations), but you must still have a fair amount of patience to compile with LTO support.
Fracture is another open-source project aiming to offer users/developers the ability to decompile binaries back into an intermediate form.
The GStreamer 1.4 release that will happen in a few weeks time is officially making OpenGL a "first class citizen" and can be used by all platforms / operating systems supporting this open-source multimedia framework.
While GNOME has been riding high lately with driving the development of its Wayland-based compositor and being the first major desktop getting there natively for most of its applications, and the overall work on the recent GNOME 3.12 release being fairly exciting, on the foundation side they are running into a budget shortfall and funds are becoming very tight within the GNOME Foundation.
A few hours ago I wrote about the most interesting features for the Linux 3.15 kernel from my perspective as it didn't look like anything else interesting would be introduced this late in the merge window before the imminent 3.15-rc1. However, this time I've been happily proven wrong with Clang patches being added to the Linux 3.15 kernel.
There's likely just a day or two left before the Linux 3.15-rc1 kernel will be released to mark the end of the Linux 3.15 kernel merge window. With all of the major features appearing to have been merged by now, here's an overview of the exciting features to look forward to with the Linux 3.15 release.

Using the AMD Athlon 5350 AM1 APU with its four "Jaguar" cores operating at 2.05GHz, I ran some benchmarks from Ubuntu 14.04 Linux comparing the performance of binaries compiled under GCC 4.8.2 and this week's GCC 4.9.0 RC1. Is GCC 4.9 better able to exploit the potential out of AMD's Jaguar microarchitecture? Let's see.
Early on in the Linux 3.15 merge window there were improvements to significantly speed-up suspend and resume for systems, but now there's another late merge of a patch that has the capability of speeding up the resume time from suspend by 7~12x for at least some laptop/desktop systems.
The GNOME EasyTAG application is a simple, open-source way for editing audio tags within popular audio file formats. The much-revamped EasyTAG 2.2.0 is now available.
