derrida writes "During the many threads discussing Ingo Molnar's recently merged Completely Fair Scheduler, Roman Zippel has repeatedly questioned the complexity of the new process scheduler. In a recent posting to the Linux Kernel mailing list he offered a simpler scheduler named the 'Really Fair Scheduler' saying, 'As I already tried to explain previously CFS has a considerable algorithmic and computational complexity. This patch should now make it clearer, why I could so easily skip over Ingo's long explanation of all the tricks CFS uses to keep the computational overhead low — I simply don't need them.'"

bsdphx writes "While Theo may have a reputation of being "difficult" in some circles, this response to the recent relicensing controversy is thoughtful and well penned. Through this whole process I've learned some new things about both GPL and BSD licensing, and especially about combining the two."

An anonymous reader writes "SCO is asking the court to enter a final judgment on the Unix ownership issues so that it can seek an immediate appeal. The logic for this, according to Groklaw Editor Pamela Jones, is that SCO would rather appeal right away so it can try all its claims at IBM, should it successfully appeal the judge's order. 'Otherwise, SCO has to wait until Novell goes through trial to a verdict and then appeal, and while it is in the appeal process, IBM would go forward in its now much smaller version, based on the August 10th ruling ... The trial starts, though, in less than a month and it will last less than a week, so none of this makes any sense if you look at a calendar. I think, therefore, it must be about FUD, so it sounds like SCO is on the move again.' The text of the request is available online. "

Jono Bacon, Community Manager for Ubuntu, has announced development on the next version of the popular Linux distribution name "Hardy Heron". "Not only will the Ubuntu community continue to do what it does best, produce an easy-to-use, reliable, free software platform, but this release will proudly wear the badge of Long Term Support (LTS) and be supported with security updates for five years on the server and three years on the desktop. We look forward to releasing the Hardy Heron in April 2008."

bsdphx writes "After years of encouragement from the OpenBSD community for others to use Reyk Floeter's free Atheros wireless driver, it seems that the Linux world is finally listening. Unfortunately, they seem to think that they can strip the BSD license right out of it."

DeviceGuru writes "A hypervisor can be used to isolate from each other software works released under incompatible licenses, while allowing them to run simultaneously on the same hardware. For example, Linux and Windows CE can run on separate virtual machines on one device, without violating either OS's license. Due to the isolation between multiple VMs running atop a hypervisor, it seems like this architecture could allow companies to build Linux-based devices, such as mobile phones or set-top boxes (think TiVo), that can't be upgraded by their users without authorization, thereby circumventing the GPLv3's 'anti-tivoization' clauses." Here's a white paper with more details from a commercial hypervisor company.

An anonymous reader writes "Linux.com has a comparison article up looking at three MythTV-focused Linux distributions. The piece looks at Mythdora, Mythbuntu, and KnoppMyth, with an eye towards ease of installation and the actual utility of the install. From the article: 'For regular system maintenance, KnoppMyth simply isn't in the same ballpark as MythBuntu and MythDora. The live CD heritage of Knoppix means you cannot update individual packages, which is fine if you like that, but for an always-on system like a MythTV back end, I'd prefer flexibility and configurability of a mainline distro. When all is said and done, if I were building my TiVo replacement today, I would do it with MythDora. MythBuntu shows a lot of promise, and I will give the final 7.10 release another look (in part because I run Ubuntu on my desktop machines), but it isn't ready yet.'" Linux.com and Slashdot are both owned by SourceForge.

jammag writes "An article at the site Datamation, entitled Becoming a Linux OEM: A Roadmap, talks about the challenges (and rewards) of selling hardware with Linux pre-installed — most likely a growth market in the years ahead. The interesting part is the description of how some smaller Linux OEMs have made it. The bottom line: surviving as a Linux OEM requires far more than making it as a Windows OEM. In particular, you have to make the systems idiot-proof for users who don't care a whit about what OS they're using."

jpatokal writes "Singapore Airlines will be rolling out the A380 superjumbo on October 26th, and a surprise awaits in the seat of every passenger: their personal Linux PC, running Red Hat. In addition to running the in-flight entertainment, passengers can also use a full copy of StarOffice, and there's a USB slot for importing/exporting documents or plugging in your own keyboard/mouse. Screen size is 10.6" (1280x768) in economy, 15.4" in business and a whopping 23" in first class (along with free noise-canceling headphones). The system is already available on current B777-300ER planes and will also be outfitted on the upcoming B787 Dreamliners."

mrcgran writes "Users of Skype for Linux have just found out that it reads the files /etc/passwd, firefox profile, plugins, addons, etc, and many other unnecessary files in /etc. This fact was originally discovered by using AppArmor, but others have confirmed this fact using strace on versions 1.4.0.94 and 1.4.0.99. What is going on? This probably shows how important it is to use AppArmor in any closed-source application in Linux to restrict any undue access to your files."

buddyglass writes "The majority of Slashdot readers are no doubt appreciative of Linux in the general sense, but I suspect we all have some application or aspect of the platform that we wish were more stable, performant, feature-rich, etc. So my question is: if you were able to devote a 'significant' number of resources (read: high-quality developers) to a particular app or area of the kernel, and were able to set the focus for those resources (stability, performance, new features, etc.), what application or kernel area would you attempt to improve, and what would aspect you focus on improving?"

RailGunSally writes "I am a (strictly technical) member of a large *nix systems admin team at a Fortune 150. Our new IT Management Overlord is a hardcore bean-counter from hell. We in the trenches have been tasked with providing 'metrics' on absolutely everything from system utilization to paper clip recycling. Of course, measuring productivity is right up there at the top of the list. We're stumped as to a definition of the basic unit of productivity for a *nix admin. There is a school of thought in our group that holds that if the PHBs are simple enough to want to operate purely from pie charts and spreadsheets, then we should just graph some output from /dev/random and have done with it. I personally love the idea, but I feel the need for due diligence, so I put the question to the Slashdot community: How does one reasonably quantify admin productivity?"

jshriverWVU writes to let us know about the release of Wine 0.9.44. Wine is a free implementation of Windows on Unix/Linux. New in this release are: better heuristics for making windows managed; automatic detection of timezone parameters; improvements to the built-in WordPad; better signatures support in crypt32; still more gdiplus functions; and of course lots of bug fixes.

keithl writes "I received a postcard in the mail today informing me that Sys Admin magazine has ceased publication. 'We regret to inform you that the magazine has ceased publication effective with the August 2007 issue.' Only paid subscribers with remaining issues receive this mailing. If you do nothing, they will send you a copy of the Sys Admin archive CD (1992 – August 2007), or you can return the card for a full refund of all unsent issues. The deadline to return the postcard for a refund is October 1, 2007." The magazine's Web site has no word that I could find on the closing down of print publication.

E5Rebel writes "Business is embracing open source like never before, but the effective demise of SCO's claims against Linux doesn't mean an end to licensing problems, an analyst warns. The debate on Slashdot seems to focus on the GPL and its virtues, but there are 1,000-plus open source licenses (according to analyst Saugatuck), and businesses face having to manage multiple licenses within a single open source product. What can be done to minimize multiple-license pain for corporate open source adopters?"

This blog entry is the step-by-step process that one administrator followed to figure out what was going on with a cracked Linux server. It's quite interesting to me, since I have had the exact same problem (a misbehaving ls -h command) on a development server quite a while back. As it turns out, my server was cracked, maybe with the same tool, and this analysis is much more thorough than the one I was able to do at the time. If you've ever wondered how to diagnose a Linux server that has been hijacked, this short article is a good starting point.

tom66 writes "Seems like a long time coming, as Microsoft today has axed it's Anti-Linux campaign 'Get the Facts', and Microsoft has replaced it with a new campaign, called 'compare'. This article touches up on why they may have done it, and the criticism surrounding Get the Facts."

dsinc writes "A guy who uploaded the latest Star Wars movie got arrested, pleaded guilty to 'conspiracy to commit copyright infringement' and 'criminal copyright infringement' and got jail and home confinement. As part of his home confinement, he agreed to install some tracking software on his computer. The problem is He's an Ubuntu Linux user and the gov't doesn't have any tracking software for Linux. So he's been told that he must use Windows for the term of his confinement. Looks like a case of cruel and unusual punishment to me"

SlinkySausage writes "Linus Torvalds has laid out his plans for the future of Linux, including the 3.0 kernel [there probably won't be one], problems with the Linux release cycles and which distro he personally runs on his home PC. '"Compile everything by hand" ones simply weren't interesting to me,' Torvalds says."

An anonymous reader writes "The all-new Linux Fund Visa Card launched on July 24th. The Linux Fund began in 1999, and lasted until Bank of America bought MBNA and canceled the program earlier this year. Before that time the fund had distributed $100,000 a year on average. US Bank has inked a new deal to resurrect the program with new features. Currently, the project is open to ideas for supporting well-loved and community-supported software that is underfunded. The current list of supported projects includes Debian, Wikipedia, FreeGeek, Freenode, and Blender."
