KDBUS is a new DBus implementation for the Linux kernel that provides greater security and better performance than the DBus daemon in user-space. Systemd in turn interfaces with KDBUS for user-space interaction. Testing was done on Fedora 20 but the systemd + KDBUS configuration should work on any modern distribution when using the newest code."

An anonymous reader writes "The Maui OS Project has made their first stable release of the Hawaii Desktop. Hawaii is still catching up with GNOME, Xfce, and KDE in terms of features, but it's written from scratch atop next-generation open-source technologies. In particular, Hawaii 0.2.0 is powered by the brand new Qt 5.2 tool-kit and runs natively on Wayland's Weston 1.3 compositor. Hawaii 0.2.0 carries all standard Linux desktop features but more advanced desktop functionality is planned while focusing around a Wayland design and eventually their own Green Island Compositor."
An anonymous reader writes "With the release of SteamOS, developing video game engines for Linux is a subject with increasing interest. This article is an initiation guide on the tools used to develop games, and it discusses the pros and cons of Linux as a platform for developing game engines. It goes over OpenGL and drivers, CPU and GPU profiling, compilers, build systems, IDEs, debuggers, platform abstraction layers and other tools."
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?"
DeviceGuru writes "One of most widely respected repositories of embedded and mobile Linux news and information has just returned to the web. LinuxDevices.com, which tracked the evolution of embedded and mobile Linux from an unknown player to being at the heart of billions of mobile and embedded devices, transferred from Ziff Davis Enterprise to QuinStreet through an acquisition two years ago, then went dormant for a year, and finally vanished from the web in May. Now, through an arrangement with QuinStreet, more than 14,000 news items and articles are back online in the form of a LinuxDevices Archive, hosted by LinuxGizmos.com. The archive is searchable from a calendar interface that lets you click on any month of any year between 1999 and 2012, to see what was going on in that time period."
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."
First time accepted submitter Maurits van der Schee writes "Where in older versions you had to add a cron job calling "fstrim" or mounting with the "discard" option in fstab, the new LTS (Long Term Stable) version of Ubuntu Linux will automatically enable TRIM for your SSD. Good news for hardware enthusiasts!"
DeviceGuru writes "Roku's popular Linux-based media players have long been criticized for their glaring omission of YouTube video support. 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."
sfcrazy writes "The Fedora Project has announced the release of Fedora 20, code named Heisenbug (release notes). 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."
sfcrazy writes "Valve Software, creator of Half-Life and Left 4 Dead, has announced that SteamOS will be available for public download on December 13. That's the day when the company will start shipping Steam Machines and Steam Controllers to the 300 selected beta participants. 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."
super_rancid writes "The team that quit Linux Format magazine to launch a competitor that pledges 50% of profits back to the Free Software community, plus the release of all its content as CC-BY-SA after nine months, have hit their ambitious £90,000 Indiegogo crowdfunding target. The campaign now includes endorsements from Karen Sandler, Executive Director of the Gnome Foundation, Eben Upton, Founder of the Raspberry Pi and Simon Phipps, President of the OSI, with the first issue promised for February 2014."
New submitter rvalles writes "Xiph.org just released a major update to their Opus audio codec. Opus 1.1 offers major improvements over last year's 1.0.2 release. Opus is a general-purpose, very flexible, open and royalty-free audio codec that offers low-latency and high quality/bitrate, incorporating technology from Skype's SILK codec and Xiph.Org's CELT codec. Its first release beat everything else last year at 64kbit/s in a listening test held at HydrogenAudio."
probain sent in this excerpt from Engadget "In case Valve's multi-tiered investment in Linux gaming weren't clear enough from SteamOS, the Steam Controller, and Steam Machines, the company's also joining the ranks of The Linux Foundation membership. 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."
DeviceGuru writes "DM&P Group has begun shipping a $39 Arduino compatible boardset and similar mini-PC equipped with a new computer-on-module based on a new 300MHz x86 compatible Vortex86EX system-on-chip. The $39 86Duino Zero boardset mimics an Arduino Leonardo, in terms of both form-factor and I/O expansion. The tiny $49 86Duino Educake mini-PC incorportates the same functionality, but in a 78 x 70 x 29mm enclosure with an integrated I/O expansion breadboard built into its top surface. The mini-PC's front and back provide 2x USB, audio in/out, Ethernet, and COM interfaces, power input, and an SD card slot. The hardware and software source for all the boards, including the computer-on-module, are available for download under open source licenses at the 86Duino.com website."
