The addition of the first U.S. carrier to the now 10-member group of mobile operators follows the earlier addition of the first Chinese (China Unicom) and Indonesian (Smartfren) carriers to the advisory group.

QML, the declarative language for designing UI-centric applications as part of Qt Quick, will also work for web-site design as part of a new KDE project. QML is an important part to Qt Quick and Qt5 while now it can also be used for designing the user-interface side of web-sites.

Officially, Red Hat still isn't saying that MariaDB, instead of Oracle's MySQL, will be its default database management system in Red Hat Enterprise Linux 7. But off-the-record people close to Red Hat tell a different story.

Last week the first Firefox OS phones went out in stores in Madrid, Spain, for sale by Telefónica. It means that if you haven’t gotten started at looking how to build your apps or your content with HTML5 and Responsive Design, now is the time. Reuse your existing HTML5 skills and content and just package it up. We’ve outlined Open Web Apps and new possibilities in detail.

The latest stats released by Google show that Android 4.1 and 4.2, aka Jelly Bean, has finally overtaken the outdated version 2.3 Gingerbread release, thanks to a rash of new phones running the OS.

While not directly Linux related, this afternoon at Phoronix we are looking at the SilverStone Air Penetrator AP123. If you're looking to make your "Tux" powered computer system a bit cooler this summer, the SST-AP123 is a great way to quietly do so.

For SUSE enterprise customers, SUSE Linux Enterprise 11 Service Pack 3 has been released today. The Nuremberg-based company calls this the first enterprise Linux distribution integrating UEFI Secure Boot support.

In this guest column, Robert Nyman, a Mozilla technical evangelist and editor of the Mozilla Hacks website, provides a perspective on the history and evolution of Firefox OS.

The latest chapter to our lengthy Intel Haswell on Linux saga is virtualization benchmarks. From Fedora 19 with the very latest software components for Linux virtualization, the performance of KVM, Xen, and VirtualBox were benchmarked from the Intel Core i7 4770K "Haswell" CPU.

David Herrmann has a GSoC project for working on DRM render and mode-set nodes and so far he has been making great progress. On Sunday he posted his second revision of his unified VMA offset manager patch-set and DRM render node work.

Along with benchmarking the AMD A10-6800K "Richland" APU on Linux and its Radeon HD 8670D graphics, I provided some GCC compiler tuning benchmarks for this AMD APU with Piledriver cores. The latest Linux testing from the A10-6800K is a comparison of GCC 4.8.1 to LLVM/Clang 3.3 on this latest-generation AMD low-power system.

For those looking to test out the long-awaited Radeon dynamic power management support within the Linux 3.11 kernel, here's some information on the new debugfs and sysfs interfaces for dealing with this "DPM" feature. The Radeon updates for the Linux 3.11 kernel are very exciting as the GPU clock speeds and voltages can dynamically adjust based upon load. This leads to power-savings when idling, especially for battery-backed systems, and also to greater performance on newer hardware by being able to up-clock the GPU from its boot speeds.

The DRM pull request has yet to be submitted for the Linux 3.11 kernel and already there is another revision to the Radeon DRM kernel driver to be submitted. This latest Radeon DRM work provides additional dynamic power management fixes and some new sysfs features...

Recent Linux kernel releases have seen a number of crypto performance optimizations for this kernel subsystem by taking advantage of newer CPU instruction set extensions for accelerating various cryptographic workloads. This theme has continued for Linux 3.11.

This morning there were the RadeonSI Gallium3D vs. AMD Catalyst Linux benchmarks for the high-end Radeon HD 7850/7950 "Southern Islands" graphics cards. While the new Southern Islands GPUs understandingly have a long way to catch up on their new open-source Linux Gallium3D driver compared to Catalyst, how is the AMD Radeon HD 8670D "Richland" APU performance between the open and closed-source drivers? Here are some benchmarks.
