Jono Bacon writes "This week at Mobile World Congress both Firefox OS and Ubuntu have been wooing the audience with their mobile offerings. CNET reviewed both and felt that Ubuntu was 'the clear winner.' From the article, 'The team thought that Ubuntu Touch, the tablet version of which we got our hands-on for the first time at MWC, feels more like the complete package at this point. We liked its slick, elegant interface that makes use of every side of the screen and puts your content and contacts front and center, minimizing the time spent hopping back to a home screen.'" They still liked Firefox OS though, and the mere existence of multiple Free Software mobile systems with carrier support is a good sign if you ask me.

An anonymous reader writes "With work done by ARM and Linaro, there is now a bootable image of Debian/Ubuntu that works for ARM64, the new 64-bit ARM architecture. There are still some caveats and work ahead, but Linux is once again the first platform that has software ready to run on a new architecture when released. This 64-bit ARM Linux support also includes the ability to run 32-bit ARM software side-by-side." You can grab a bootable rootfs, but there's no hardware to actually run it on now (the developers are using the free-as-in-beer simulator from ARM). Kernel support for the architecture was released around a year ago; this is more a tale of getting from a bootable kernel to a bootable operating system.
This is a Google Hangout interview with Keith Bergelt, Chief Executive Officer of the Open Invention Network (OIN), which was jointly founded by IBM, NEC, Novell, Philips, Red Hat, and Sony to share their relevant patents with all Linux and Open Source developers and users in order to prevent patent troll attacks on FOSS, such as the famous SCO vs. IBM lawsuits that hampered Linux adoption during the early 2000s. It costs nothing to become a an OIN licensee, and over 500 companies have done so. Few people know, however, that individual developers and FOSS users can become OIN licensees; that you are welcome to do so, and it costs nothing. Read their license agreement, sign it, and send it in. That's all it takes. They also buy patents and accept patent donations. And "...if your company is being victimized by any entity seeking to assert its patent portfolio against Linux, please contact us so that we can aid you in your battle with these dark forces." This OIN service is called Linux Defenders 911. We hope you never need to use it, but it's good to know it's there if you do need it.
sfcrazy writes "Quite a lot of people raised their eyebrows the way ex-Red Hat developer Matthew Garrett made Microsoft the 'universal' control of any desktops PCs running with UEFI secure boot. Though the intentions of Garrett were clear — to enable GNU/Linux to be able to run Linux on Windows 8 certified PCs with secure boot; it was clearly putting Microsoft in a very powerful position. Linus, while a supporter of secure boot, exploded at Garrett and Howells when they proposed its inclusion in the kernel. Linus responded: 'Guys, this is not a d*#@-sucking contest. If you want to parse PE binaries, go right ahead. If Red Hat wants to deep-throat Microsoft, that's *your* issue. That has nothing what-so-ever to do with the kernel I maintain. It's trivial for you guys to have a signing machine that parses the PE binary, verifies the signatures, and signs the resulting keys with your own key. You already wrote the code, for chissake, it's in that f*cking pull request.'" Update: 02/25 17:24 GMT by U L : The headline/article are misleading, since mjg seems to agree that the patch is a bit complicated : "(I mean, *I'm* fine with the idea that they're *@#$ing idiots and deserve to be miserable, but apparently there's people who think this is a vital part of a business model)". The issue at hand is a set of patches to load and store keys inside of a UEFI PE binary which is then passed to the kernel, which then extracts the keys from the binary. It's absurd, it's messy, and it's only needed because Microsoft will only sign PE binaries so not supporting it makes restricted boot even more difficult to support.
bill_mcgonigle writes "I just bought bitcoins from the World's first Bitcoin ATM at Liberty Forum. I created an account using an Android Bitcoin client and held up its QR code to the Raspberry Pi-based device's optical scanner. After I fed in a $20 Federal Reserve Note, I got back a confirmation QR code on its display, which I then scanned and checked the third-party confirmation URL. The machine can function on any wireless network and will soon be available for purchase by merchants, who can make a commission on customers' Bitcoin purchases."
kthreadd writes "Minix, originally designed as an example for teaching operating system theory which was both inspiration and cause for the creation of Linux has just been released as version 3.2.1. Major new features include full support for shared libraries and improved support for USB devices such as keyboards, mice and mass storage devices. The system has received many performance improvements and several userland tools have been imported from NetBSD."
An anonymous reader writes "The first release candidate of Debian Installer 7.0 Wheezy was released this week. Debian 7.0 is set to introduce a number of new features including optional systemd support, a real-time Linux kernel option, UEFI installation support, and the Debian Installer now supports WPA/WPA2 wireless networks. More Debian 7.0 features are listed on the Debian Wiki and the 7.0 RC1 installer can be downloaded at Debian.org." Update: 02/21 16:12 GMT by S : Changed headline and summary to reflect that it was the Installer release candidate, not the distribution.
jrepin writes "The Tizen 2.0 source code and SDK are now available. 'This release includes an enhanced Web framework that provides state-of-the-art HTML5/W3C API support, a Web UI framework (including full-screen and multi-window support), additional Tizen device APIs, such as Bluetooth and NFC support, and access to the device's calendar, call history, and messaging subsystems are now available. Other highlights: The Web Runtime framework supports new configuration elements for specifying the required features and privileges, and provides the basic runtime environment for NPRuntime plugins; the Native framework supports full-featured application development and provides a variety of features such as background applications, IP Push, and TTS (Text-To-Speech)."
hypnosec writes "Keeping its promise from yesterday Ubuntu has announced an operating system for tablets dubbed 'Ubuntu for Tablets' that it says will work on tablets of any size. Advertised to work on both entry level tablets as well as high-end tablets with enterprise specifications, the operating system offers multitasking, safer sharing, instant launch of applications through the menu bar on the left, effortless switching between applications among other features." The tablet version of the OS will also be presented at Mobile World Congress later this month. Also featured at SlashCloud.
diegocg writes "Linux kernel 3.8 has been released. This release includes support in Ext4 for embedding very small files in the inode, which greatly improves the performance for these files and saves some disk space. There is also a new Btrfs feature that allows for quick disk replacement, a new filesystem F2FS optimized for SSDs; support for filesystem mount, UTS, IPC, PID, and network namespaces for unprivileged users; accounting of kernel memory in the memory resource controller; journal checksums in XFS; an improved NUMA policy redesign; and, of course, the removal of support for 386 processors. Many small features and new drivers and fixes are also available. Here's the full list of changes."
With the Linux 3.8 merge over, the Intel Linux graphics developers are looking toward 3.9. From a weblog entry by one of them: "Let's first look at bit at the drm core changes: The headline item this time around is the reworked kernel modeset locking. Finally the kernel doesn't stall for a few frames while probing outputs in the background! ... For general robustness of our GEM implementation we've clarified the various gpu reset state transitions. This should prevent applications from crashing while a gpu reset is going on due to the kernel leaking that transitory state to userspace. Ville Syrjälä also started to fix up our handling of pageflips across gpu hangs so that compositors no longer get stuck after a reset. Unfortunately not all of his patches made it into 3.9. Somewhat related is Mika Kuoppala's work to fix bugs across the seqnqo wrap-around. And to make sure that those bugs won't pop up again he also added some testing infrastructure. " The thing I am most looking forward to is the gen4 relocation regression finally being fixed. No more GPU hangs when under heavy I/O load (the bane of my existence for a while now). The bug report is a good read if you think hunting for a tricky bug is fun.
nk497 writes "Canonical has revealed that a developer preview of Ubuntu for phones will arrive next week, on the 21st of February. The touch preview will initially only be available for the Galaxy Nexus and Nexus 4 smartphones, but Canonical plans to support more devices. The release is designed to let developers create apps — and to give 'enthusiasts' a sneak peek — ahead of the smartphone side of Ubuntu arriving in version 13.10 in October. Canonical suggested that the OS will initially only support low-end smartphones, but the group plans to also support higher-end models, too, and the OS will work across mobile devices, PCs and TVs."
sl4shd0rk writes "Valve has finally released Steam for Linux. Although some of the 57 games listed on the Linux Steam site are previously released from the Humble Bundles, there are others which should provide adequate entertainment for anyone bored with the HB games. Among the games listed, many at deep discounts of 50%-75% off, are HalfLife, CounterStrke Source and Serious Sam 3. Hopefully Valve will keep the ports coming as rumor has it that Left 4 Dead had been ported at least for developers."
An anonymous reader writes "The Khronos Group has published the first products that are officially conformant to OpenGL ES 3.0. On that list is the Intel Ivy Bridge processors with integrated graphics, which support OpenGL ES 3.0 on open-source Linux Mesa. This is the best timing yet for Intel's open-source team to support a new OpenGL standard — the standard is just six months old whereas it took years for them to support OpenGL ES 2.0. There's also no OpenGL ES 3.0 Intel Windows driver yet that's conformant. Intel also had a faster turn-around time than NVIDIA and AMD with the only other hardware on the list being Qualcomm and PowerVR hardware. OpenGL ES 3.0 works with Intel Ivy Bridge when using the Linux 3.6 kernel and the soon-to-be-out Mesa 9.1." Phoronix ran a rundown of what OpenGL ES 3.0 brings back in August.
