jones_supa writes "The x32 ABI for Linux allows the OS to take full advantage of an x86-64 CPU while using 32-bit pointers and thus avoiding the overhead of 64-bit pointers. Though the x32 ABI limits the program to a virtual address space of 4GB, it also decreases the memory footprint of the program and in some cases can allow it to run faster. The ABI has been talked about since 2011 and there's been mainline support since 2012. x32 support within other programs has also trickled in. Despite this, there still seems to be no widespread interest. x32 support landed in Ubuntu 13.04, but no software packages were released. In 2012 we also saw some x32 support out of Gentoo and some Debian x32 packages. Besides the kernel support, we also saw last year the support for the x32 Linux ABI land in Glibc 2.16 and GDB 7.5. The only Linux x32 ABI news Phoronix had to report on in 2013 was of Google wanting mainline LLVM x32 support and other LLVM project x32 patches. The GCC 4.8.0 release this year also improved the situation for x32. Some people don't see the ABI as being worthwhile when it still requires 64-bit processors and the performance benefits aren't very convincing for all workloads to make maintaining an extra ABI worthwhile. Would you find the x32 ABI useful?"

sfcrazy writes "Ironically while Netflix's infrastructure runs on Linux and Open Source technologies, the service doesn't support Linux, the platform. Netflix is available for Mac, Windows, iOS, Android and Chrome OS but not for desktop Linux. One of the reasons could be that Netflix still uses Microsoft's Silverlight which is not supported on Linux. However Linux users have managed to get it to work on their distros. Now openSUSE users can also run Netflix using Pipelight."

As of Dec. 17, that is no longer the case, provided you have the high-end Roku 3 player and live in the U.S., Canada, Ireland, or the U.K. Google's YouTube channel is available immediately for the Roku 3 in resolutions up to 1080p, and will be supported on additional models (though probably just Roku 2) next year, according the company. Previously, the only way to run YouTube over a Roku box was to use the third-party, subscription based PlayOn service, which requires a connected PC or Mac running the PlayOn app. The YouTube update also adds a Send to TV feature, letting you send videos to the Roku for display on the TV with a single click."

Fedora 20 is dedicated to Seth Vidal, the lead developer of Yum and the Fedora update repository, who recently died in a road accident. Gnome is the default DE of Fedora, and so it is for Fedora 20. However unlike Ubuntu (where they had to create different distros for each DE) Fedora comes with KDE, XFCE, LXDE and MATE. You can install the DE of your choice on top of base Fedora."
jones_supa writes "SteamOS has been further inspected to see what kind of technical solutions it uses. The Debian-based OS uses Linux 3.10, shipping with a heap of patches applied, with the most focus being on real-time-like features. The kernel is also using aufs and they seem to be sitting on some bug fixes for upstream on top of that. The kernel is not using the new Intel P-State driver, with the reported reason being, 'it causes issues with sound being choppy during BigPicture trailer video playback.' SteamOS is using SysVinit as its init system. The desktop is backed by X.Org server 1.12.4 and a custom desktop compositor which seems to be a 4,200-line patch on xcompmgr. Catalyst and Mesa components can be found on the system, but so far only NVIDIA is officially supported. The system boots into Big Picture Mode, but the user can drop into a GNOME desktop. Responsible for a great deal of the kernel changes, SteamOS compositor work, and other SteamOS code is Pierre-Loup A. Griffais, a.k.a. 'Plagman'. He was a NVIDIA employee dealing with their Linux support. Another Valve employee doing lots of the SteamOS system-level work is John Vert, who up until last year was a Microsoft employee since 1991. There's also other former Microsoft employees on Valve's Linux team, like Mike Sartain."
An anonymous reader writes that, as promised, "Valve has put out their first SteamOS Linux operating system beta. SteamOS 1.0 'Alchemist' Beta is forked from Debian Wheezy and features its own graphics compositor along with other changes. Right now SteamOS 1.0 is only compatible with NVIDIA graphics cards and uses NVIDIA's closed-source Linux driver. SteamOS can be downloaded from here, but the server seems to be offline under the pressure."
Qedward writes "Munich's switch to open source software has been successfully completed, with the vast majority of the public administration's users now running its own version of Linux, city officials said today. In one of the premier open source software deployments in Europe, the city migrated from Windows NT to LiMux, its own Linux distribution. LiMux incorporates a fully open source desktop infrastructure. The city also decided to use the Open Document Format (ODF) as a standard, instead of proprietary options. Ten years after the decision to switch, the LiMux project will now go into regular operation, the Munich City council said."

The company said, 'SteamOS will be made available when the prototype hardware ships. It will be downloadable by individual users and commercial OEMs. (But unless you're an intrepid Linux hacker already, we're going to recommend that you wait until later in 2014 to try it out.)"
jones_supa writes "This announcement comes from the ubuntu-desktop mailing list. Due to GNOME Control Center already being a heavily patched version in Ubuntu, Canonical is planning to found their own fork called Unity Control Center. This would be a fork with a limited lifespan and later on they would move to something called Ubuntu System Settings, an in-house project. For now, a PPA has been set up to test the new fork."
DeviceGuru writes "AirTame has developed an AirPlay-like protocol and HDMI dongle for 1080p video streaming and screen mirroring from PCs to PCs and TVs, and has substantially exceeded its $160,000 Indiegogo funding goal. AirTame streams from Windows, Mac, and Linux PCs to other PCs via apps at both ends, and to TVs via the HDMI dongle, and also offers a multicast mode for broadcasting to multiple PCs and TVs for use in classrooms or conferences. But at least initially, there won't be support for Android or iOS devices in the mix, due OS restrictions. The company says it plans to release AirTame's software, API, and protocol source code under a dual-license enabling free use with GPL-like restrictions, and paid use for commercial applications requiring proprietary modifications."

Valve Linux head Mike Sartain calls the news, 'one of the many ways Valve is investing in the advancement of Linux gaming;' he sees the move as yet another step for Valve toward its bigger goal of popularizing accessible Linux-based gaming." Cloudius Systems and the HSA Foundation also joined the Linux Foundation today.
An anonymous reader writes "Intel's open-source Linux graphics driver is now running neck-and-neck with the Windows 8.1 driver for OpenGL performance between the competing platforms when using the latest drivers for each platform. The NVIDIA driver has long been able to run at similar speeds between Windows and Linux given the common code-base, but the Intel Linux driver is completely separate from their Windows driver due to being open-source and complying with the Linux DRM and Mesa infrastructure. The Intel Linux driver is still trailing the Windows OpenGL driver in supporting OpenGL4."

rjmarvin writes "Docker 0.7 was released today, with 7 major new features including support to run on all Linux distributions. No longer capable solely on running on Debian and Ubuntu Linux, Docker 0.7 adds support for distributions such as Red Hat, SUSE, Gentoo and Arch. From the announcement: 'A key feature of Docker is the ability to create many copies of the same base filesystem almost instantly. Under the hood Docker makes heavy use of AUFS by Junjiro R. Okajima as a copy-on-write storage mechanism. AUFS is an amazing piece of software and at this point it’s safe to say that it has safely copied billions of containers over the last few years, a great many of them in critical production environments. Unfortunately, AUFS is not part of the standard linux kernel and it’s unclear when it will be merged. This has prevented docker from being available on all Linux systems. Docker 0.7 solves this problem by introducing a storage driver API, and shipping with several drivers. Currently 3 drivers are available: AUFS, VFS (which uses simple directories and copy) and DEVICEMAPPER, developed in collaboration with Alex Larsson and the talented team at Red Hat, which uses an advanced variation of LVM snapshots to implement copy-on-write. An experimental BTRFS driver is also being developed, with even more coming soon: ZFS, Gluster, Ceph, etc. When the docker daemon is started it will automatically select a suitable driver depending on its capabilities.'"

jones_supa writes "As can be recalled, Mir didn't make it to the Ubuntu 13.10 release to replace X.org as the display server. Back then it suffered of problems in multi-monitor support, along with other issues. Now it turns out that Canonical's product will not make it even into the next LTS version (14.04) of the Ubuntu desktop. Mir itself would be ready for showtime in the schedule, but there are problems with XMir, which is the X11 compatibility layer that ensures Mir can work with applications built for X. The comments came at the Ubuntu Developer Summit: in an online event Mark Shuttleworth stressed that the 14.04 desktop has to be rock-solid for customers with large-scale deployments, such as educational institutions. In the meantime, you can already try out Mir in your Ubuntu system."
sfcrazy writes "The openSUSE team just announced the release of openSUSE 13.1. There are some core points which set openSUSE apart from the popular Ubuntu distro. While Ubuntu has become a more or less Canonical-owned project, openSUSE is becoming more and more community-driven. Looking at the recent controversies around Ubuntu and their move toward mobile platforms, openSUSE seems to be a great option for desktop users."
jones_supa writes "During the first day of the latest virtual Ubuntu Developer Summit, Canonical developers finally plotted out the enabling of TRIM/DISCARD support by default for solid-state drives on Ubuntu 14.04. Ubuntu developers aren't looking to enable discard at the file-system level since it can slow down delete operations, so instead they're wanting to have their own cron job that routinely runs fstrim for TRIMing the system. In the past there has been talk about the TRIM implementation being unoptimized in the kernel. Around when Linux 3.0 was released, OpenSUSE noted that the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance."
An anonymous reader writes "TechRepublic has the story behind Munich City Council's decision to ditch Microsoft Windows and Office in favor of open source software. The project leader talks about why the shift was primarily about freedom, in this case freeing itself from being tied into Microsoft's infrastructure and having control over the software it uses. He talks about how the council managed to keep such a large project on track, despite affecting 15,000 people and spanning nine years. He also warns against organizations justifying the shift to open source software on the grounds that it will save money, arguing this approach is always likely to fail."
sfcrazy writes "Ubuntu developer Oliver Grawert does not prefer to do online banking with Linux Mint. In the official mailing list of the distribution, Ubuntu developers stated that the popular Ubuntu derivative is a vulnerable system and people shouldn't go for online banking on it. One of the Ubuntu developers, Oliver Grawert, originally pointed out that it is not necessary that security updates from Ubuntu get down to Linux Mint users since changes from X.Org, the kernel, Firefox, the boot-loader, and other core components are blocked from being automatically upgraded." Clement Lefebvre, the Linux Mint project founder, has since made a statement and confirmed that Oliver Grawert seems "more opinionated than knowledgeable" adding "the press blew what he said out of proportion."
The Raspberry Pi project that we've been fans of for quite a while now has hit a new milestone: Today, they announced that as of the last week in October, the project has sold more than two million boards. Raspberry Pi is anything but alone in the tiny, hackable computer world (all kinds of other options, from Arduino to the x86-based Minnowboard, are out there, and all have their selling points), but the low price, open-source emphasis, and focus on education have all helped the Pi catch on. If yours is one of these 2 million, what are you using it for? (And if you favor some other small system for your own experiments, what factors matter?)

But as core Linux kernel developers grow older, there's a very real concern about ensuring younger generations are getting involved. In this post, Open Access supporter Luis Ibanez shares some exciting stats about recent releases of the Linux kernel, but also warns that 'Maintaining the vitality of this large community does not happen spontaneously. On the contrary, it requires dedication and attention by community members on how to bring new contributors on board, and how to train them and integrate them alongside the well-established developers.'"
Gordon Haff and Richard Morrell. Richard says this about himself: "I'm Red Hat's Cloud Security Blogger and Cloud Evangelist based in Europe. Passionate about good code and Open Hybrid Cloud. Founder of SmoothWall protecting millions of networks for 13 years globally. My blogging and my podcasting is my own editorial and does not represent the views of Red Hat..." We have known Richard since the 20th Century, so this interview has been a long time coming. In it, he talks about how Red Hat is working to become as strong in the Open Source cloud world as it already is in GNU/Linux. This interview may not "represent the views of Red Hat," but it obviously represents the views of a loyal Red Hat employee who is also a long-time Linux enthusiast.

Linus also took the opportunity to share possible plans for Linux 4.0. He's thinking of tagging Linux 4.0 following the Linux 3.19 release in about one year and is also considering the idea of Linux 4.0 being a release cycle with nothing but bug-fixes. Does Linux really need an entire two-month release cycle with nothing but bug-fixing? It's still to be decided by the kernel developers."

While building upon the existing Intel Linux GPU driver, the kernel driver changes are significant in size for Broadwell. Code comments from Intel indicate that these processors shipping in 2014 will have "some of the biggest changes we've seen on the execution and memory management side of the GPU" and "dwarf any other silicon iteration during my tenure, and certainly can compete with the likes of the gen3->gen4 changes." Come next year, Intel may now be able to better take on AMD and NVIDIA discrete graphics solutions."

Being a Linux-fanboy since the mid-nineties, I'm now looking for a good audio processing/editing/enhancing setup that can run on different platforms, the most important being Linux. Are there any suggestions for Open Source or proprietary audio editing software that run on Linux?"
jfruh writes "Apple is now offering upgrades to the latest version of OS X for free. When Linux inventor Linus Torvalds was asked whether this threatened Linux (presumably by someone who had only a passing knowledge of all the things 'free' can mean when applied to software) it gave him an opportunity for a passionate defense of open source. Torvalds also says that he'll keep programming until it gets 'not interesting,' which hasn't happened yet." The newest version of OS X may be gratis for Apple hardware buyers, but it's notably far from the original, (literally) un-branded sense of "mavericks."
nk497 writes "Linus Torvalds has welcomed the arrival of Valve's Linux-based platform, SteamOS, and said it could boost Linux on desktops. The Linux creator praised Valve's 'vision' and suggested its momentum would force other manufacturers to take Linux seriously — especially if game developers start to ditch Windows. Should SteamOS gain traction among gamers and developers, that could force more hardware manufacturers to extend driver support beyond Windows. That's a sore point for Torvalds, who slammed Nvidia last year for failing to support open-source driver development for its graphics chips. Now that SteamOS is on the way, Nvidia has opened up to the Linux community, something Torvalds predicts is a sign of things to come. 'I'm not just saying it'll help us get traction with the graphics guys,' he said. 'It'll also force different distributors to realize if this is how Steam is going, they need to do the same thing because they can't afford to be different in this respect. They want people to play games on their platform too.'"
colinneagle writes "I installed Ubuntu Touch "1.0" on my first-generation Nexus 7 tablet and have been using it as my main tablet system for the last four days. Here's how it went. First off, the installation was surprisingly painless. I followed the official instructions and didn't encounter a single problem. That being said, the installation is really geared toward software developers, power users or people already comfortable on a Linux command line. If you're not in one of those categories, I recommend holding off for the time being. Once installed, Ubuntu Touch booted up rather quickly — in only just a few seconds (a fair bit faster than Android 4.x on the same tablet). And, immediately, I was presented with a short tutorial that appears the first time the system is booted, which, I might add, has got to be one of the slickest, least annoying tutorials I've seen. But... there were problems. The battery life was, to put it mildly, terrible. Performance has been mixed, and the OS was prone to what I call 'The Pulsating Seizure Feature' a few dozen times over the weekend. In a nutshell: launching apps (and, occasionally, moving between apps) can cause the device to freeze and begin flashing the screen rapidly."
Via Phoronix comes news that the new DRM driver for the Freedreno driver for Qualcomm Snapdragon Adreno graphics is gaining a few new features in Linux 3.13: "After a year of working on the 'Freedreno' Gallium3D user-space driver and getting that up to speed for Qualcomm Adreno/Snapdragon support, for the past few months he's been working on a complementary kernel driver rather than relying upon Qualcomm's Android-focused kernel layer. ... The work that Rob has ready for Linux 3.13 with this Qualcomm DRM graphics driver is DRI PRIME support, support for render nodes, updated header files, plane support, and a couple of other changes."

And at the heart of its operations is a virtual data center powered by off-the-shelf server hardware, various flavors of Linux, and over 6 million lines of software code. From the article: 'Called the Common Display System, or CDS (pronounced as "keds" by those who work with it), the three-screen workstations in the operations center are powered by a collection of quad-processor Intel motherboards in an armored case, which gives new meaning to the nautical phrase "toe buster." Even the commanding officer's and executive officer's chairs on the bridge have CDS workstations built-in. Each CDS system runs multiple LynxOS-based Linux virtual machines, which can run on various networks partitioned by security level and purpose. '"

We speak to Canonical founder and Ubuntu creator Mark Shuttleworth who tells us what to expect." Adds reader jrepin: "Kubuntu Linux 13.10 has just been released and is available for download. It comes with KDE Software Compilation 4.11, a new application for discovering and installing software, a simpler way to manage your system users. and a new Network Manager applet gives a simpler UI for connecting to a range of network types. You can now setup Wifi networking from the installer making it easier to install updates and extra packages during the install." ZDNet has a fairly tepid review of the incremental rather than startling improvements of the new release, and notes "Ubuntu 14.04 LTS, due for release on 17 April next year, will now perhaps come as even more of a shock if its promised big changes are fully realised."
