Running ZFS Natively On Linux Slower Than Btrfs 235

Posted by kdawson from the early-days dept.
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."

Attachmate To Acquire Novell For $2.2B Cash 221

Posted by kdawson from the old-order-passeth dept.
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.

Alternative To the 200-Line Linux Kernel Patch 402

Posted by timothy from the you-go-first dept.
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."

Is Linux At the End of Its Life Cycle? 676

Posted by CmdrTaco from the don't-cycles-repeat dept.
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?"

The ~200 Line Linux Kernel Patch That Does Wonders 603

Posted by CmdrTaco from the well-isn't-that-special dept.
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.'"

Windows Cluster Hits a Petaflop, But Linux Retains Top-5 Spot 229

Posted by timothy from the heating-up-the-whole-outdoors dept.
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."

Fedora Project Drops SQLNinja 'Hacker' Tool 159

Posted by kdawson from the dual-use dept.
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."

Kernel Tracing With LTTng On Ubuntu Maverick 88

Posted by kdawson from the truth-of-kernel dept.
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?"

CDE — Making Linux Portability Easy 385

Posted by timothy from the namespace-collision dept.
ihaque writes "A Stanford researcher, Philip Guo, has developed a tool called CDE to automatically package up a Linux program and all its dependencies (including system-level libraries, fonts, etc!) so that it can be run out of the box on another Linux machine without a lot of complicated work setting up libraries and program versions or dealing with dependency version hell. He's got binaries, source code, and a screencast up. Looks to be really useful for large cluster/cloud deployments as well as program sharing. Says Guo, 'CDE is a tool that automatically packages up the Code, Data, and Environment involved in running any Linux command so that it can execute identically on another computer without any installation or configuration. The only requirement is that the other computer have the same hardware architecture (e.g., x86) and major kernel version (e.g., 2.6.X) as yours. CDE allows you to easily run programs without the dependency hell that inevitably occurs when attempting to install software or libraries. You can use CDE to allow your colleagues to reproduce and build upon your computational experiments, to quickly deploy prototype software to a compute cluster, and to submit executable bug reports.'"

Red Hat's Secret Patent Deal 95

Posted by Soulskill from the where-do-penguinburgers-come-from-anyway dept.
Bruce Perens writes "When patent troll Acacia sued Red Hat in 2007, it ended with a bang: Acacia's patents were invalidated by the court, and all software developers, open-source or not, had one less legal risk to cope with. So, why is the outcome of Red Hat's next tangle with Acacia being kept secret, and how is a Texas court helping to keep it that way? Could the outcome have placed Red Hat in violation of the open-source licenses on its own product?"
