The State of Linux IO Scheduling For the Desktop? 472

pinkeen writes "I've used Linux as my work & play OS for 5+ years. The one thing that constantly drives me mad is its IO scheduling. When I'm copying a large amount of data in the background, everything else slows down to a crawl while the CPU utilization stays at 1-2%. The process which does the actual copying is highly prioritized in terms of I/O. This is completely unacceptable for a desktop OS. I've heard about the efforts of Con Kolivas and his Brainfuck Scheduler, but it's unsupported now and probably incompatible with latest kernels. Is there any way to fix this? How do you deal with this? I have a feeling that if this issue was to be fixed, the whole desktop would become way more snappier, even if you're not doing any heavy IO in the background." Update: 10/23 22:06 GMT by T : As reader ehntoo points out in the discussion below, contrary to the submitter's impression, "Con Kolivas is still actively working on BFS, it's not unsupported. He's even got a patch for 2.6.36, which was only released on the 20th. He's also got a patchset out that I use on all my desktops which includes a bunch of tweaks for desktop use." Thanks to ehntoo, and hat tip to Bill Huey.

Who Invented the Linux-Based Wireless Router? 154

mtaht writes "I've just had the interesting experience of being deposed to talk about one of the first embedded, Linux-based, wireless routers. Our (free!) 1998 publication of how to make one predates patent #7035281, filed September 13, 2000, by someone else. Their patent was recently granted and is now being disputed in court, in part using our how-to as an example of prior art. The lawsuit continues; the case goes before a judge shortly, and a jury trial if necessary is scheduled for the spring. I find myself plagued with the question: So... who invented the embedded Linux based wireless router? What relevance does 'who' have, when there is such an enormous confluence of ideas from thousands of people? What constitutes invention, anyway?"

Open Source-Friendly Smartphones For the Small Office? 222

Thunderstruck writes "I work in a small office with just two computers. Both machines run long-term-service releases of Ubuntu, with Gnome, and Evolution for scheduling, contact management and electronic mail. We plan to stick with Linux long-term. For telephone service, we're using smartphones. In order to keep everything straight, we need phones that can synchronize easily with the calendars and contact data on each owner's desktop machine. We cannot use cloud based services for this function due to ethics rules, and for security reasons. Right now, we do all of this with older Palm phones, but these are a dying breed. What options are out there right now for phones that will sync with Evolution (or another good Linux PIM suite) which do not require data to go through the cloud first?"

RDS Protocol Bug Creates a Linux Kernel Hole, Now Fixed 89

Trailrunner7 writes "The open-source Linux operating system contains a serious security flaw that can be exploited to gain superuser rights on a target system. The vulnerability, in the Linux implementation of the Reliable Datagram Sockets (RDS) protocol, affects unpatched versions of the Linux kernel, starting from 2.6.30, where the RDS protocol was first included." The article goes on to say, though, that "Linux installations are only vulnerable if the CONFIG_RDS kernel configuration option is set, and if there are no restrictions on unprivileged users loading packet family modules, as is the case on most stock distributions," and that Linus Torvalds has committed a fix.

Red Hat CEO Says Software Vendor Model Is Broken 223

alphadogg writes "The current model of selling commercial enterprise software is broken, charged the CEO for Red Hat. It is too expensive, doesn't address user needs and, worst of all, it leaves chief information officers holding all the risk of implementing new systems. 'The business models between customer and vendors are fundamentally broken,' said Jim Whitehurst, speaking Wednesday at the Interop conference in New York. 'Vendors have to guess at what [customers] want, and there is a mismatch of what customers want and what they get. Creating feature wars is not what the customer is looking for.' Whitehurst estimated that the total global IT market, not including telecommunications, is about $1.4 trillion a year. Factor in the rough estimates that half of all IT projects fail or are significantly downgraded, and that only half of all features in software packages are actually used, then it would follow that 'easily $500 billion of that $1.4 trillion is fundamentally wasted every year,' he said."

Desktop Linux Is Dead 1348

digitaldc writes with this quote from PCWorld: "It kills me to say this: The dream of Linux as a major desktop OS is now pretty much dead. Despite phenomenal security and stability — and amazing strides in usability, performance, and compatibility — Linux simply isn't catching on with desktop users. And if there ever was a chance for desktop Linux to succeed, that ship has long since sunk. ... Ultimately, Linux is doomed on the desktop because of a critical lack of content. And that lack of content owes its existence to two key factors: the fragmentation of the Linux platform, and the fierce ideology of the open-source community at large."

Linux To Take Over Microsoft In Enterprises 237

shougyin writes "For years, Linux has enjoyed much of its success as a replacement for Unix. Companies turned to Linux to replace Unix servers, or for new deployments within a Unix-heavy environment. Linux is still king there, but it's starting to encroach on Microsoft as well. Big companies are planning overwhelmingly (76.4%) to add more Linux servers in the next year, and less than half (41.2%) of the companies are planning to add Windows servers in the next year. Even more interesting, nearly half (43.6%) are actively planning to decrease use of Windows servers in the next year."

Microsoft Admits OpenOffice.org Is a Contender 480

ChiefMonkeyGrinder writes "Microsoft has unwittingly admitted that OpenOffice.org is a rival, by launching a three-minute video of customers explaining why they switched to Microsoft Office from OpenOffice.org. Glyn Moody writes: 'You don't compare a rival's product with your own if it is not comparable. And you don't make this kind of attack video unless you are really, really worried about the growing success of a competitor. [Microsoft] has now clearly announced that OpenOffice.org is a serious rival to Microsoft Office, and should be seriously considered by anyone using the latter.'"

Mozilla Releases Firefox 4 Beta For Android, Maemo 128

An anonymous reader writes "Mozilla has released the first beta of its Firefox 4 for Android and Maemo. The browser is based on the Firefox 4 core and should be released in the same time frame as the big brother. The mobile browser includes Firefox Sync, a cloud feature that enables users to sync browsing history, passwords, form-fill data and bookmarks, as well as open tabs." Android news site Androinica also mentions the release, and provides a small tutorial on installing beta apps for Android.
