digitaldc writes with this excerpt from Gamasutra: "The Air Force Research Laboratory (AFRL) has connected 1,760 PlayStation 3 systems together to create what the organization is calling the fastest interactive computer in the entire Defense Department. The Condor Cluster, as the group of systems is known, also includes 168 separate graphical processing units and 84 coordinating servers in a parallel array capable of performing 500 trillion floating point operations per second (500 TFLOPS), according to AFRL Director of High Power Computing Mark Barnell."

itwbennett writes "In late October we learned that starting with the next release (11.04), Ubuntu would use Unity instead of GNOME as its default desktop interface. Now we know a bit more about what that will (and won't) mean for users. The move to Unity doesn't mean that Ubuntu is abandoning GNOME. It also doesn't mean that users will be forced to use Unity; they'll still be able to revert to the old GNOME interface. What it does mean, mainly, is that users will be presented with a simple interface — probably too simple for nuts and bolts types. The more 'radical shift' will be switching Ubuntu's base graphics system from the X Window System to Wayland. There users can expect that it will take some time before things are in working order. 'In other words,' says Steven Vaughan-Nichols who reviewed Unity for ITworld, 'Wayland will be an option, and one that only people who don't mind having their desktops blow up on a regular basis should fool with, in Ubuntu 11.04. By Ubuntu 11.10, it will be workable, and come the spring release two years from now, Ubuntu 12.04, we should, if all goes well, see a stable Wayland-based Unity desktop.'"

rocket22 writes "Not long ago Linus Torvalds made some comments about issues the kernel maintainers were facing while applying the 'feature branch' pattern. They are using Git (which is very strong with branching and merging) but still need to take care of the branching basics to avoid ending up with unstable branches due to unstable starting points. While most likely your team doesn't face the same issues that kernel development does, and even if you're using a different DVCS like Mercurial, it's worth taking a look at the description of the problem and the clear solution to be followed in order to avoid repeating the same mistakes. The same basics can be applied to every version control system with good merge tracking, so let's avoid religious wars and focus on the technical details."

An anonymous reader writes "This might very well be the nerdiest site we'll ever encounter... Linux Radio is an online radio station broadcasting the Linux kernel! Each time someone visit the site, a random source file is selected and read loudly by a virtual speaker materialized through the open source speech synthesizer eSpeak. Will it prove useful to anyone is probably a difficult question to answer, but the excitement provided is worth experiencing at least once. However, this concept proves once more the advantages of open source over proprietary software making such achievements impossible : whoever in his right mind would want to listen to binary files loudly?"

dmbkiwi writes "The first beta release of KDE SC 4.6 was released yesterday. OpenSUSE had packages up almost immediately, so being curious as to what's new, I've downloaded and upgraded to the new release. These are my impressions thus far."

binstream writes "To support Linux game development, Unigine Corp. announced a competition: it will give a free license for its Unigine engine to a seasoned team willing to work on a native Linux game. The company has been Linux-friendly from the very start; it released advanced GPU benchmarks (Heaven, Tropics, Sanctuary) for Linux before and is working on the OilRush strategy game that supports Linux as well."

Responding to yesterday's post indicating that Ubuntu might move to a rolling release schedule, reader ddfall writes "This is wrong! Engineering Director of Ubuntu Rick Spencer says 'Ubuntu is not changing to a rolling release.' He goes on to say, 'We are confident that our customers, partners, and the FLOSS ecosystem are well served by our current release cadence. What the article was probably referring to was the possibility of making it easier for developers to use cutting edge versions of certain software packages on Ubuntu. This is a wide-ranging project that we will continue to pursue through our normal planning processes.'"

formfeed writes "The register claims that 'Ubuntu is moving away from its established six-month-cycle and potentially to a future where software updates land on a daily basis.' While this sounds like a sudden change, it is apparently more of a long-term thought. The Register quotes Shuttleworth: '"Today we have a six-month release cycle," Shuttleworth said. "In an internet-oriented world, we need to be able to release something every day. That's an area we will put a lot of work into in the next five years. The small steps we are putting in to the Software Center today, they will go further and faster than people might have envisioned in the past."' But given that many of Shuttleworth's thoughts became decisions later on, it might be interesting to see, where this one leads. Interestingly enough, five years is about the time when Ubuntu will run out of letters."

k-s writes "Linux, the GNU userland and Enlightenment and its foundation libraries (EFL) are known for their resource efficiency and flexibility, key components for embedded products. Today it was announced that such features led them to be used in a fridge that runs Linux and X11 with EFL. The Freescale i.MX25 based fridge by Electrolux (Frigidaire) provides the expected bits such as temperature controls and pre-set modes (vacation, party) as well as a special purpose drawer that cools your drinks and food with a beautiful UI. It also ships with handful applications for contacts, calendar, reminder, digital picture frame and even an illustrated recipe book from a famous Brazilian magazine."

An anonymous reader writes "Yesterday AMD released open source Linux driver support for their Fusion APUs, primarily for the first Ontario processor. As detailed on Phoronix, this includes support for kernel mode-setting, 2D acceleration, and 3D acceleration via both Mesa and Gallium3D graphics drivers."

jfruhlinger writes "Word came down this morning that when Attachmate bought Novell, certain intellectual property rights were sold to a Microsoft-led consortium as part of the deal. Since Unix is the most valuable piece of IP Novell owns, there was a certain amount of panic that suddenly Redmond is in charge of this foundational technology for Linux and a number of other open source projects. But, while MS is being cagey, Brian Proffitt doubts that Unix was part of the IP package that was sold — and believes that Linux would be safe even if it were."

An anonymous reader writes "It's been known that ZFS is coming to Linux in the form of a native kernel module done by the Lawrence Livermore National Laboratory and KQ Infotech. The ZFS module is still in closed testing on KQ infotech's side (but LLNL's ZFS code is publicly available), and now Phoronix has tried out the ZFS file-system on Linux and carried out some tests. ZFS on Linux via this native module is much faster than using ZFS-FUSE, but the Solaris file-system in most areas is not nearly as fast as EXT4, Btrfs, or XFS."

wiredmikey and a few others wrote in to let us know that Novell has agreed to be acquired by Attachmate Corporation for $6.10 per share in cash, in a transaction valued at approximately $2.2 billion. The Boston Globe reports that the deal also includes the sale of some intellectual assets to a consortium organized by Microsoft. Attachmate plans to operate Novell and SUSE as separate business units. Here is the press release.

climenole writes "Phoronix recently published an article regarding a ~200 line Linux Kernel patch that improves responsiveness under system strain. Well, Lennart Poettering, a Red Hat developer, replied to Linus Torvalds on a mailing list with an alternative to this patch that does the same thing yet all you have to do is run 2 commands and paste 4 lines in your ~/.bashrc file."

Glyn Moody writes "That's what Nikolai Pryanishnikov, president of Microsoft Russia, seems to think. Quoted in the context of continuing questions about Russia's plans to create its own national operating system based on GNU/Linux, Pryanishnikov said [via Google Translate]: 'We must bear in mind that Linux is not a Russian OS and, moreover, is at the end of its life cycle.' An off-the-cuff comment, or something more?"

An anonymous reader writes "There is a relatively miniscule patch to the Linux kernel scheduler being queued up for Linux 2.6.38 that is proving to have dramatic results for those multi-tasking on the desktop. Phoronix is reporting the ~200 line Linux kernel patch that does wonders with before and after videos demonstrating the much-improved responsiveness and interactivity of the Linux desktop. While compiling the Linux kernel with 64 parallel jobs, 1080p video playback was still smooth, windows could be moved fluidly, and there was not nearly as much of a slowdown compared to when this patch was applied. Linus Torvalds has shared his thoughts on this patch: So I think this is firmly one of those 'real improvement' patches. Good job. Group scheduling goes from 'useful for some specific server loads' to 'that's a killer feature.'"

angry tapir writes "In an effort to expand software compatibility for its upcoming Fusion chips, AMD has joined rival Intel's efforts to develop the open-source MeeGo OS. AMD 'will provide engineering expertise intended to help establish the technical foundations for next-generation mobile platforms and embedded devices,' the company said in a blog post on its website."

Twice a year, Top500.org publishes a list of supercomputing benchmarks from sites around the world; the new results are in. Reader jbrodkin writes "Microsoft says a Windows-based supercomputer has broken the petaflop speed barrier, but the achievement is not being recognized by the group that tracks the world's fastest supercomputers, because the same machine was able to achieve higher speeds using Linux. The Tokyo-based Tsubame 2.0 computer, which uses both Windows and Linux, was ranked fourth in the world in the latest Top 500 supercomputers list. While the computer broke a petaflop with both operating systems, it achieved a faster score with Linux, denying Microsoft its first official petaflop ranking." Also in Top-500 news, reader symbolset writes with word that "the Chinese Tianhe-1A system at the National Supercomputer Center in Tianjin takes the top spot with 2.57 petaflops. Although the US has long held a dominant position in the list things now seem to be shifting, with two of the top spots held by China, one by Japan, and one by the US. In the Operating System Family category Linux continues to consolidate its supercomputing near-monopoly with 91.8% of the systems — up from 91%. High Performance Computing has come a long way quickly. When the list started as a top-10 list in June of 1993 the least powerful system on the list was a Cray Y-MP C916/16526 with 16 cores driving 13.7 RMAX GFLOP/s. This is roughly the performance of a single midrange laptop today."

simonb writes, "In what can only be described as a fit of insanity, the Fedora Board have declared a 'hacker tool' not fit for entry into their software repositories. Today your SQL injection tools, tomorrow your nmap?" The Register links the Fedora board's meeting minutes. From the story: "The move came on Monday in a unanimous vote by the Fedora Project's board of directors rejecting a request that SQLNinja be added to the archive of open-source applications. It came even as a long list of other hacker tools are included in the bundle and was harshly criticized by some security watchers. 'It seems incredibly short sighted to reject software based on perceived legal usage,' said Jacob Appelbaum, a full-time programmer for the Tor Project. 'They have decided to become judges of likely usage based on their own experience. That is a path of madness.' ... [T]he board unanimously decided to add a new statement to Fedora's legal guidelines concerning the inclusion of hacking tools. ... Smith said the language is intended to clarify its stance on a class of software that can be used both to secure and penetrate protected networks."

francis-giraldeau writes "Linux Tracing Toolkit (LTTng) provides high-performance kernel tracing for Linux. This is the killer app for system level debugging and performance tuning. It's now easier than ever to install, with packages released for Ubuntu Maverick. The short introduction to kernel tracing shows how to interpret a simple kernel trace and relate it to strace. I would like to ask Slashdot readers what they would expect as features for a kernel tracing analysis tool, because I'm starting my PhD on this topic and looking for ideas. Also, I wonder why LTTng is not mainline yet. Will Linus Torvalds see the light in 2011?"
