jones_supa writes "When GCC 4.9 is released in 2014 it will be coming in hot on new features with a large assortment of improvements and new functionality for the open-source compiler. Phoronix provides a recap of some of the really great features of this next major compiler release from the Free Software Foundation. For a quick list: OpenMP 4.0, Intel Cilk Plus multi-threading support, Intel Bay Trail and Silvermont support, NDS32 port, Undefined Behavior Sanitizer, Address Sanitizer, ADA and Fortran updates, improved C11 / C++11 / C++14, better x86 intrinsics, refined diagnostics output. Bubbling under are still: Bulldozer 4 / Excavator support, OpenACC, JIT compiler, disabling Java by default."

An anonymous reader writes "There's many improvements due in the Linux 3.13 kernel that just entered development. On the matter of new hardware support, there's open-source driver support for Intel Broadwell and AMD Radeon R9 290 'Hawaii' graphics. NFTables will eventually replace IPTables; the multi-queue block layer is supposed to make disk access much faster on Linux; HDMI audio has improved; Stereo/3D HDMI support is found for Intel hardware; file-system improvements are on the way, along with support for limiting the power consumption of individual PC components."

An anonymous reader writes "Linus Torvalds announced the Linux 3.12 kernel release with a large number of improvements through many subsystems including new EXT4 file-system features, AMD Berlin APU support, a major CPUfreq governor improvement yielding impressive performance boosts for certain hardware/workloads, new drivers, and continued bug-fixing. 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."

An anonymous reader writes "Intel shipped open-source Broadwell graphics driver support for Linux this weekend. 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."

An anonymous reader writes "Debian has been one of the last holdouts using SysVinit over a modern init system, but now after much discussion amongst Debian developers, they are deciding whether to support systemd or Upstart as their default init system. The Debian technical committee has been asked to vote on which init system to use, which could swing in favor of using Upstart due to the Canonical bias present on the committee."

noahfecks writes "It seems that the GCC developers are taking steps to roll out significant improvements after CLANG became more competitive. 'Among the highlights to look forward to right now with GCC 4.9 are: The Undefined Behavior Sanitizer has been ported to GCC; Ada and Fortran have seen upgrades; Improved C++14 support; RX100, RX200, and RX600 processor support; and Intel Silvermont hardware support.'"

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."

An anonymous reader writes "NFTables is queued up for merging into the Linux 3.13 kernel. NFTables is a four-year-old project by the creators of Netfilter to write a new packet filtering / firewall engine for the Linux kernel to deprecate iptables (though it now offers an iptables compatibility layer too). NFTables promises to be more powerful, simpler, reduce code complication, improve error reporting, and provide more efficient handling of packet filter rules. The code was merged into net-next for the Linux 3.13 kernel. Iptables will still be present until NFTables is finished, but it is possible to try it out now. LWN also has a writeup on NFTables."

An anonymous reader writes "The jor1k is an interesting open-source toy emulator project to emulate a 32-bit OpenRISC OR1000 processor, 63MB of RAM, ocfb frame-buffer, and ATA-hard drive ... all in JavaScript. Though JavaScript based, there are asm.js optimizations and the performance seems to be quite decent in modern web browsers. The jor1k OpenRISC emulator can do a lot, even handle running the Linux kernel, GCC compiler, ScummVM Monkey Island, and the Wayland/Weston compositor, all from within the web browser."

An anonymous reader writes "Mesa and its open-source Intel graphics driver now are in compliance with the OpenGL 3.2 specification (PDF). It took four years for Mesa to get up to GL 3.2 / GLSL 1.50 compliance, and support for the other Mesa drivers isn't too far behind, but they're still years behind in supporting OpenGL 4. Supporting a major new OpenGL API has resulted in Mesa 10.0 being called the next release. It has many other features, like performance improvements and new Gallium3D features. OpenGL 3.3 support might also be completed prior to the Mesa 10.0 release in November."

jones_supa writes "A new major version of the classic GNU Make software has been released. First of all, Make 4.0 has integration support for GNU Guile Scheme. Guile is the extension system of the GNU project that is a Scheme programming language implementation and now in the Make world will be the embedded extension language. 4.0 also features a new 'output-sync' option, 'trace-enables' for tracing of targets, a 'none' flag for the 'debug' argument, and the 'job server' and .ONESHELL features are now supported under Windows. There are also new assignment operators, a new function for writing to files, and other enhancements. It's been reported that Make 4.0 also has more than 80 bug-fixes. More details can be found from their release announcement on the mailing list."

An anonymous reader writes "NVIDIA was caught removing features from their Linux driver and days later Linux developers have caught and confirmed AMD imposing artificial limitations on their graphics cards in the DVI-to-HDMI adapters that their driver will support. Over years AMD has quietly been adding an extra EEPROM chip to their DVI-to-HDMI adapters that are bundled with Radeon HD graphics cards. Only when these identified adapters are detected via checks in their Windows and Linux Catalyst driver is HDMI audio enabled. If using a third-party DVI-to-HDMI adapter, HDMI audio support is disabled by the Catalyst driver. Open-source Linux developers have found this to be a self-imposed limitation and that the open-source AMD Linux driver will work fine with any DVI-to-HDMI adapter."

An anonymous reader writes "Valve has revealed their first Steam Machines prototype details. The first 300 Steam Machine prototypes to ship will use various high-end Intel CPUs and NVIDIA GPUs while running their custom SteamOS Linux distribution. The Intel Haswell CPU + NVIDIA GPU combination should work well on Linux with the binary drivers. Using a range of CPUs/GPUs in the prototypes will allow them to better gauge the performance and effectiveness. Valve also said they will be releasing the CAD design files to their custom living room console enclosure for those who'd like to reproduce them." Valve is careful to point out that these specs aren't intended as a standard: "[T]o be clear, this design is not meant to serve the needs of all of the tens of millions of Steam users. It may, however, be the kind of machine that a significant percentage of Steam users would actually want to purchase — those who want plenty of performance in a high-end living room package. Many others would opt for machines that have been more carefully designed to cost less, or to be tiny, or super quiet, and there will be Steam Machines that fit those descriptions."

jones_supa writes "Things are starting to look even better for the status of open specifications for AMD Radeon HD hardware. AMD's Alex Deucher announced via his personal blog that programming guides and register specifications on the 3D engines for the Evergreen, Northern Islands, Southern Islands, and Sea Islands GPUs are now in the NDA-free public domain. These parts represent the 3D engines on the Radeon HD 5000 through Radeon HD 8000 series graphics processors."

An anonymous reader writes "Ubuntu 13.10 is due for release later this month, and the Ubuntu developers were planning to replace the native X Server with Mir/XMir as Canonical's next-generation Ubuntu display server. However, they have now decided Mir will not be the Ubuntu 13.10 default on the desktop over the XMir X11 compatibility layer suffering multi-monitor issues and other problems. Canonical still says they will use Mir for Ubuntu Touch 13.10 images and remain committed to the Mir project."

An anonymous reader writes "The FreeBSD Release Engineering Team has announced the release of FreeBSD 9.2. FreeBSD 9.2-RELEASE has ZFS TRIM SSD support, ZFS LZ4 compression support, DTrace hooks and VirtIO drivers as part of the default kernel configuration, unmapped I/O support, and numerous other minor features. FreeBSD also announced FreeBSD 10.0 Alpha 4 on the same day, which is the next major feature release of the open-source BSD operating system."

An anonymous reader writes "LLVM's libc++ standard library (an alternative to GNU libstdc++) now has full support for C++1y, which is expected to become C++14 next year. Code merged this week implements the full C++1y standard library, with support for new language features in the Clang compiler frontend nearly complete." GCC has some support for the soon-to-be standard too. The C++ standards committee is expected to produce a more or less final draft in just a few weeks. The LLVM and GCC C++14 status pages both have links to the proposals for the new features.

An anonymous reader writes "Select to copy and middle-click to paste. That's very convenient usability feature associated with UNIX graphical environments. But it is confusing for new users, so the ability to middle-click paste was briefly removed from GNOME 3.10. It was restored few days later, but with clear message: middle-click paste will be permanently removed from next GNOME version." I hope that "we'll defer this change until the next cycle" also means that it's getting re-thought, rather than just delayed.

An anonymous reader writes "The openSUSE Linux distribution looks like it may be the first major Linux distribution to ship the Btrfs file-system by default. The openSUSE 13.1 release is due out in November and is still using EXT4 by default, but after that the developers are looking at having openSUSE using Btrfs by default on new installations. The Btrfs features to be enabled would be the ones the developers feel are data-safe."

An anonymous reader writes "One week ahead of the GNOME 3.10 release, all of the basic Wayland support for GNOME has been merged. With today's GNOME Shell 3.9.92 release the Wayland branch was merged and there was also an updated Mutter Wayland release, besides earlier GNOME 3.9.x packages fostering the Wayland support. Fedora 20 is expected to ship with GNOME on Wayland as a technology preview. Additional details about the current GNOME Wayland support are available from the GNOME Wiki."

Slashdot's Timothy Lord is attending LinuxCon in New Orleans this week and writes in with the following. "Valve co-founder and managing director Gabe Newell says in no uncertain terms what the brain trust at Valve thinks: When it comes to actual users, 'Linux is currently insignificant by any metric' (by any metric that matters to game companies, at least, like number of players, minutes played, and — all important — revenue). On these fronts, Linux players are 'typically under 1 percent' of what game companies see. But that's not the upshot. The takeaway is just about the opposite, says Newell: 'The future of gaming is on Linux.' Newell expounded on the present and future of games on Linux in a keynote address at LinuxCon North America, which kicked off today in New Orleans. He described ways Valve is working to improve the landscape for games on Linux, and hinted at new hardware developments from the company in the near future." Keep reading for the rest of Tim's report. Since Valve's 1996 founding, the company has come out with a rash of well-known games including Half-life, Counterstrike, and Portal, for personal computers as well as the console market. In that time, though, Valve, like the rest of the computer world, has gone through structural changes driven by the falling costs of both computers and bandwidth. These, says Newell, have increased the relative value of design and game quality in general, but also marketing and — crucially — distribution paths. That has ramifications throughout the games industry, including the emergence and growth of online delivery for games and updates. (Valve’s own system, Steam, is up to 50 million users by itself; the console infrastructure is even bigger: Sony claimed that many users three years ago). The changes in relative costs have also spurred free to play models and large-scale e-sports. (Large scale is no joke: According to Newell, "At the last tournament we held, we had over a million people watching it simultaneously.")

Newell describes a trend toward end-users being involved, though, not just as spectators, but as content creators. He describes this in fairly sweeping terms: “Games will becomes nodes in a linked economy, where the majority of digital goods and services are user generated.” That sounds a bit grandiose, perhaps, but it’s grounded in numbers. “The Team Fortress community creates 10 times the amount of content [that developers do],” says Newell. While he says Valve has always been happy to compete with other game studios (“we’re a little bit cocky”), “the one entity we wouldn’t ever want to compete with is our own users; they’ve already outstripped us dramatically. It’s not by a little bit; it’s an order of magnitude already.” Broad-based distributed development like that is what open source has been whipping up in the world of software for decades.

Creating games or games content, though, isn’t for the faint of heart: centralized online app stores (Apple’s in particular) “put an enormous number of roadblocks in front of doing that,” including developer approval as well as vetting individual apps and updates to them. In that context, he says, few users have the stubbornness or wherewithal to get through that. A more streamlined system for taking advantage of eater player/developers is needed.

“Several years ago, we thought ‘OK, if our model is correct, we need to help making Linux a good gaming plaform for users and developers.” To that end, Valve makes for a case study in how Linux has been creeping in: the company shipped the first dedicated games server running Linux in 1999. Now, most games servers run Linux (now several hundred thousand — and “probably a million”).

Those game servers are dishing up prodigious loads of data: “Near as we can tell, we’re generating something like 2 to 3 percent of worldwide mobile and land-based IP traffic, and that tends to startle people who don’t realize what a large sea change is going on. Even ignoring game servers, we’ve delivered over an exabyte of data year to date.” (Internally, he says, there’s approximately 20TB of content in a Linux-based version control system. This, says Newell, is true for companies like Bungie, too.)

Impressive as those data-shoveling numbers are, they don’t exactly shout desktop (or living room) success. But steps that Valve (along with other companies) has taken make it easier to swallow the claim. “Several years ago, we thought ‘OK, if our model is correct, we need to help make Linux a good gaming plaform for users and developers.” The first major move, says Newell, was to get a game — a real, graphics-intensive game — going on Linux. The process, though, revealed a “sweater thread” of issues, revealing flaws in in all parts of the stack: faulty drivers, gaps between Linux distributions’ included software, pitfalls in the user experience, and flaws in the company’s Steam tools.

In the course of resolving problems in each of those layers, “The good thing is that if we get a game like Left for Dead running, we’ve probably worked through issues for lots of developers. We’ve definitely solved problems for the Call of Duty team, or Tour of Duty, or whatever. The games aren’t that different; the key thing is to get changes all the way through for users. In February, we shipped [the Linux] Steam client; today -- at least when I got on the plane -- Valve has 198 games running on Linux.“

The bug-fixing and code-developing isn’t just a sporadic effort; the company has “several guys on SDL,” started by current Valve employee Sam Lantinga, and is co-developing a new Linux debugger, in addition to the work they’ve done on the LLVM debugger.

Making Linux a better platform for games is necessary, but may not be sufficient in itself, though. Platforms tend to cluster not just by operating system, but by context: platform, mobile, and console games don’t always play nicely: “As a user, I shoudn’t have to buy new games, or have new friends, or whatever, just because I’m sitting on a couch.” With Linux certainly a more-than-viable software platform for games, but still in the chicken-and-egg world of low user and revenue numbers that discourage spending developer time on Linux end users, Newell says the next step is necessary work on the hardware side of the equation, to smooth the open-source path between the developer and back-end data handling side of the games business to actual end-users.

“One of the things we had to do, is we're staging out the different pieces we think are necessary for staging to make Linux the future of gaming,” said Newell. “Our next step, having done these other pieces, is on the hardware side. There are thermal issues and sound issues, but also a lot of input issues.” He closed with this tease: “Our next step on this is to release some stuff we’ve done on the hardware side. Next week we’re going to be rolling out more information about how we get there, and what are the hardware opportunities we see for getting Linux into the living room."

An anonymous reader writes "The first alpha release of FreeBSD 10.0 is now available for download. FreeBSD 10 features include replacing GCC with LLVM/Clang, VPS support, an AMD Radeon KMS support, Raspberry Pi support, Bhyve for HVN virtualization, and ARM EABI support."

First time accepted submitter noahfecks writes "After the Linux 3.11 kernel was codenamed 'Linux for Workgroups' in memory of Microsoft Windows for Workgroups 3.11, Linus Torvalds is using 'Suicidal Squirrel' as the Linux 3.12 kernel codename." Seems only fitting. (The list of kernel names should reflect this soon.)

jones_supa writes "The sudden death of a solid-state drive in Linus Torvalds' main workstation has led to the work on the 3.12 Linux kernel being temporarily suspended. Torvalds has not been able to recover anything from the drive. Subsystem maintainers who have outstanding pull requests may need to re-submit their requests in the coming days. If the SSD isn't recoverable he will finish out the Linux 3.12 merge window from a laptop."

An anonymous reader writes "With the LLVM/Clang migration, FreeBSD developers have now disabled building GCC and the GNU C++ standard library (libstdc++) as part of the FreeBSD base system. GCC and libstdc++ have been superseded by LLVM's Clang and libc++, respectively, on primary architectures for FreeBSD 10.0." You can still flip a few switches to get GCC, but the system compiler will still be clang. Update: 09/11 14:50 GMT by U L : Reader Noryungi noted that the What's Cooking for FreeBSD 10 page is also worth a look, adding "I have to say, this is shaping up to be a very interesting release. Bhyve [the BSD hypervisor], in particular, sounds very promising."

An anonymous reader writes "Just days after Intel added XMir support to their Linux graphics driver so it would work with the in-development the X11 compatibility layer to the Mir display server premiering with Ubuntu 13.10, Intel management has rejected the action and had the XMir patch reverted. There's been controversy surrounding Mir with it competing with Wayland and the state of the display server being rather immature and its performance coming up short while it will still debut in Ubuntu 13.10. Intel management had to say, "We do not condone or support Canonical in the course of action they have chosen, and will not carry XMir patches upstream." As a result, Canonical will need to ship their own packaged version of the Intel (and AMD and Nouveau drivers) with out-of-tree patches."

It turns out the X.Org Foundation had put in quite a lot of work to become a non-profit organization, with guidance from the Software Freedom Law Center. They got in trouble after failing to routinely file their taxes on time. There's also been a host of other X.Org accounting errors in recent years. There was also the recent news of the IRS going after open-source projects, too."

An anonymous reader writes "It was on this day 22 years ago when Linus Torvalds humbly announced Linux and today he played on that in announcing the Linux 3.11-rc7 kernel release. The final Linux 3.11 kernel release is expected in about one week."

An anonymous reader writes "With Netflix continuing to rely upon Microsoft Silverlight, the video streaming service hasn't been supported for Linux users as the Mono-based 'Moonlight' implementation goes without Silverlight 5 DRM support. However, there is now Netflix support for Linux-based web-browsers via the open source Pipelight project. Pipelight supports Netflix and other Silverlight-based web applications by having a Netscape plug-in that in turn communicates with a Windows program running under Wine. The Windows program then simulates a browser to load the Silverlight libraries. Netflix then works as the Pipelight developers implemented support for the Netflix DRM scheme within Wine."

FreeBSD offers a binary Linux compatibility layer to run games at the same (or better) performance as Linux, but unfortunately it's capped to running Linux x86 binaries and NVIDIA is the only GPU vendor with proper BSD graphics driver support."

An anonymous reader writes "Picking up the code from a failed Direct3D 10/11 implementation for Linux, a working Direct3D 9 state tracker has been implemented for Linux. The Direct3D 9 support works with open-source Linux GPU hardware drivers via Mesa's Gallium3D and can run games for the open-source Radeon and Nouveau drivers without simply converting the Direct3D commands into OpenGL. Unlike the experimental D3D10/11 code from the past, this D3D9 state tracker is already running games like Skyrim, Civilization 5, Anno 1404, and StarCraft 2. With Linux games not natively targeting D3D, Wine was modified for using this native Direct3D implementation."

An anonymous reader writes "Wayland 1.2 & Weston 1.2 have been released. Features of this quarterly update to the X.Org/Mir display competitor is support for color management, a new input method framework, a Raspberry Pi renderer/back-end, HiDPI output scaling, multi-seat improvements, and various other changes for this next-generation Linux desktop display protocol and compositor."

An anonymous reader writes "Canonical has announced today that they intend to ship the Mir Display Server by default in Ubuntu 13.10, rather than Ubuntu 14.04 as originally planned. They moved ahead their Mir adoption since the code is materializing and they want Mir/XMir widely tested prior to the Ubuntu 14.04 Long-Term Support release. Mir in Ubuntu 13.10 will be using the XMir X11 compatibility layer to run the Unity 7 desktop and there will be fallback support for running an X.Org Server if the graphics drivers don't support Mir."

An anonymous reader writes "AMD's open-source developer has posted an incredible set of 165 patches against the Linux kernel that provide support for a few major features to their Linux graphics driver. Namely, the open-source Radeon Linux driver now supports dynamic power management on hardware going back to the Radeon HD 2000 (R600) generation. The inability to re-clock the GPU frequencies and voltages dynamically based upon load has been a major limiting factor for open-source AMD users where laptops have been warm and there is diminished battery power. The patches also provide basic support for the AMD Radeon HD 8000 'Sea Islands' graphics processors on their open-source Linux driver."

An anonymous reader writes "Through the use of XMir, a translation layer for running legacy X11 applications atop Ubuntu's forthcoming Mir display server, the GNOME Shell, Xfce, and LXDE desktops now run on this X.Org Server alternative. With XMir, the traditional window managers are still running while Mir treats these desktops as a single window."

jones_supa writes "This discovery comes nicely alongside the celebration of FreeBSD's 20th birthday, for all the UNIX nerds. The operating system powering the PlayStation 4 is Orbis OS, which is a Sony spin of FreeBSD 9.0. It's not a huge surprise FreeBSD is being used over Linux, in part due to the more liberal licensing. The PlayStation 4 is x86-64 based now rather than Cell-based, which makes it easier to use FreeBSD. BSDs in general currently lack manufacturer supported full-feature AMD graphics driver, which leads to the conclusion that Sony and AMD have likely co-developed a discrete driver for the PS4. Some pictures of the development kit boot loader (GRUB) have been published too."

An anonymous reader writes "With the upcoming KDE 4.11, there's an initial Wayland backend through the KWin manager. The author notes on his blog: 'Once the system is fully started you can just use it. If everything works fine, you should not even notice any difference, though there are still limitations, like only the three mouse buttons of my touchpad are supported ;-)'"

An anonymous reader writes "In clearing up common misconceptions about Wayland (e.g. it breaking compatibility with the Linux desktop and it not supporting remote desktops like X), Eric Griffith (a Linux developer) and Daniel Stone (a veteran X.Org developer) have written The Wayland Situation in which they clearly explain the facts about the shortcomings of X, the corrections made by Wayland, and the advantages to this alternative to Canonical's in-development Mir."

An anonymous reader writes "The open-source Intel Linux graphics driver has hit a milestone of now being faster than Apple's own OpenGL stack on OS X. The Intel Linux driver on Ubuntu 13.04 is now clearly faster than Apple's internally-developed Intel OpenGL driver on OS X 10.8.3. when benchmarked from a 'Sandy Bridge' class Mac Mini. Only some months ago, Apple's GL driver was still trouncing the Intel Linux Mesa driver."

Via Phoronix comes news that Ubuntu is revisiting replacing Firefox with Chromium as the default browser. Reasons include that Chromium is the basis of Ubuntu Touch and their new web apps platform, and using a single browser for all versions of Ubuntu would simplify maintenance. From the article: "Expressed shortcomings of switching to Google's Chromium open-source web-browser is that data migration from Firefox isn't too obvious, extensions don't migrate between browsers, Chromium isn't supported on all architectures (e.g. PowerPC), the browser doesn't work with the Orca screen reader and doesn't integrate well for accessibility reasons, there is no native PDF plug-in, and Chromium is said to have worse performance under memory pressure. There were also some concerns expressed about differences with WebApps in Chromium. ... It looks like the switch to Chromium will happen in the name of a better user experience for the desktop with Chrome/Chromium now arguably surpassing Firefox in its features and performance while pushing Chromium as the default leads to a more consistent experience across Ubuntu form factors from phones/tablets to the desktop." The Ubuntu community will have their input solicited as the next step. The Ubuntu Developer Summit session has notes and a full video of today's discussion.

An anonymous reader writes "While complementing Debian APT/DPKG, Canonical is now developing their own package format. The new package format has promised highlights of having no dependencies between applications, each package would install to its own directory, root support wouldn't always be required, and overall a more self-contained and easier approach for developers than it stands now for Debian/Ubuntu packages. The primary users of the new packaging system would be those distributing applications built on the Ubuntu Touch/Phone SDK. The initial proof-of-concept package management system is written in Python and uses JSON representation." This quote from the post by Canonical's Colin Watson bears repeating: "We'll continue to use dpkg and apt for building the Ubuntu operating system, syncing with Debian, and so on."
