The OMAP4660 dual-core 1.2GHz ARM Cortex-A9 development board generally loses out to Intel's older competition, but does manage to win in ray-tracing and other tests, and is advantageous on a per-Watt basis."

First time accepted submitter parkejr writes "I started off building a media library a few years ago with an old PC running Ubuntu. Folders for photos, ogg vorbis music from my CD collection, and x264 encoded mkv movies. I have a high spec machine for encoding, but over the years I've moved the server to a bigger case, with 8 TB of disk capacity, and reverted back to Debian, but still running with the same AMD Sempron processor and 2GB RAM. It's working well, it's also the family mail server, and the kids are starting to use it for network storage, and it runs both link and twonkyserver, but my disks are almost full, and there are no more internal slots. The obvious option to me is to add in a couple of SATA PCI cards, to give me 4 more drives, and buy an externally powered enclosure, but that doesn't feel very elegant. I'm a bit of an amateur, so I'd like some advice. Should I start looking at a rack system? Something that can accommodate, say, 10 3.5" drives (I'm thinking long term, and some redundancy)? Also, what about location — I could run some cat6 to the garage and move it out of the house, in case noise is an issue. Finally, what about file format, file system, and OS/software? I'm currently running with ext3 and Debian Squeeze. Happy with my audio encoding choice, but not sure about x264 and mkv. I'd also consider different media server software, too. Any comments appreciated."

xmas2003 writes "Over at Linux.com, Zonker writes about Alek's Controllable Christmas Lights for Celiac Disease. This annual Internet tradition uses a hi/low-tech combo of LAMP'ed Redhat Web Servers, a 7+ year old Thinkpad running Ubuntu for the X10 control, and an old-school webpage design that could be politely described as Web 0.0 — wait until you see the animated cursor — D'OH! The site is free (and totally fun) as it also raises awareness and donations for Celiac Disease — over $70,000 to the University of Maryland. Nifty pictures of the crazy christmas display can be seen on the Christmas Blog (notice Clifford Stoll's The Cuckoo's Egg in post #220) plus watch videos of it in action with comedic history. Nothing quite says Christmas like a giant, inflatable HULK wearing a Santa Hat... along with three wise men of Elmo, SpongeBob, and Homer Simpson. The Slashdot Effect of turning 21,000 Christmas lights ON & OFF this evening should provide quite a Christmas Eve show to Alek's neighbors... and also the International Space Station."

brothke writes "If there ever was a book that should not be judged by its title, Defense against the Black Arts: How Hackers Do What They Do and How to Protect against It, is that book. Even if one uses the definition in The New Hackers Dictionary of 'a collection of arcane, unpublished, and (by implication) mostly ad-hoc techniques developed for a particular application or systems area', that really does not describe this book. The truth is that hacking is none of the above. If anything, it is a process that is far from mysterious, but rather aether to describe. With that, the book does a good job of providing the reader with the information needed to run a large set of hacking tools." Read below for the rest of Ben's review.

First time accepted submitter clava writes "We have a desktop Java testing application that is going to be administering tests to students on lab computers running Ubuntu 10.x. These computers are used by the students for other purposes and we're not allowed to create special users or change the OS configuration. When the testing app is launched, we need to restrict users from exiting the app so they can't do things like search the internet for answers or use other applications. Is there a good way to put an Ubuntu machine in kiosk mode or something via our application and have exiting kiosk mode be password protected? Any ideas are appreciated."

rsk writes "Since the Ubuntu One desktop synchronization service was launched by Canonical it has always been powered by CouchDB, a popular document-oriented NoSQL data store with a powerful master-master replication architecture that runs in many different environments (servers, mobile devices, etc.). John Lenton, senior engineering manager at Canonical, announced that Canonical would be moving away from CouchDB due to a few unresolvable issues Canonical ran into in production with CouchDB and the scale/requirements of the Ubuntu One service. Instead, says Lenton, Canonical will be moving to a custom data storage abstraction layer (U1DB) that is platform agnostic as well as datastore agnostic; utilizing the native datastore on the host device (e.g. SQLite, MySQL, API layers, 'everything'). U1DB will be complete at some point after the 12.04 release."

MrSeb writes "In the Linux world, a war has been raging for a couple years. At stake are the hearts and minds of its user base. The combatants: the various distributions of Linux itself. For some time, Ubuntu Linux has been the clear leader in the fight, amassing more users than any other. Canonical and its baby seemed poised to take over the Linux desktop/laptop market completely — until it released Unity. Unity has caused an uproar in the Linux community — especially amongst the power users who decry its lack of customizability and inability to scale on big- and multi-monitor setups — and users are defecting in droves to Linux Mint, now the second most popular Debian-based distro and gaining fast on Ubuntu. Mint has very similar commands and shortcuts to Ubuntu, runs most apps the same as Ubuntu, and you can customize it to look and feel exactly how you want — which, for most users of Linux, is exactly what they want."

tearmeapart writes "It may be time again for another discussion/flamewar on the reasons why a lot of us are (still) using Microsoft. The last big discussion on Slashdot was close to 10 years ago, and a lot has changed since then: Windows XP and 7 have proven to be stable (and memories of Windows ME are mostly gone.) There are many more distributions for Linux, especially commercial options. Distributions like Ubuntu and CentOS have made GNU/Linux more friendly. Options for word processing, spreadsheets, etc. have grown. Apple and their products have changed considerably, though their philosophy hasn't. Microsoft Silverlight came and is on the way out. Wine and solutions like Transgaming have matured. So... why are a lot of us still using Windows? What would it take for us to switch?"

Brad1138 writes "You see complaints about the 'next gen' GUI's all over the place, but do we really all hate them? Personally, I don't like them — I tried very hard to like Unity in Ubuntu 11.04/11.10 before giving up and switching to Mint (I am very happy there currently). But is it the vocal minority doing all the complaining, or is it the majority? Are we just too set in our ways?"

itwbennett writes "The Banshee music application, and Mono, the open source implementation of Microsoft's .NET framework, on which Banshee is dependent, may be excluded from the next release of Ubuntu. In 'a blog entry titled Bansheegeddon,' Banshee and Mono developer Joseph Michael Shields says the reasons given for the change are that Banshee is 'not well maintained' and 'porting music store to GTK3 is blocked on banshee ported to GTK3.' Other reasons mentioned but not in the session logs are complaints that it doesn't work on ARM. Ubuntu Community Manager Jono Bacon pointed out in a blog post that the decision to drop Banshee, Mono or other apps that are dependent on Mono has not been finalized. But the blogosphere is lit up with speculation that this is a deliberate move to exclude Mono because of its emulation of Microsoft .NET."

gbl08ma writes "According to various sources, the ISO image size for the upcoming Long-Term Support Ubuntu version 'Precise Pangolin' will not fit on a regular CD, since the image size is expected to weigh around 750MB instead of the usual ~700MB. The idea is that users should either flash the image to a USB flash drive or burn it to a DVD. The extra room on the disc image could allow for integration of more GNOME3 components and Canonical applications. There was also a proposal to use a 1.5GB DVD image as the default download for Ubuntu 12.04."

jfruhlinger writes "In a world where 'app' is the new buzzword, the development of native Linux apps is lagging. Some of this can be attributed to the usual community infighting (the latest version of which is argument about Ubuntu's Unity interface), but there may be something deeper at play: Linux advocates have for so long advocated browser-accessed software as a service as a way to break out of Microsoft's proprietary desktop. Now that this world has arrived, there's less incentive to work on native Linux apps. But of course, entrusting your functionality and data to a cloud provider like Google has its own set of concerns for free software fans."

darthcamaro writes "There are a lot of us that really don't like Unity. Ubuntu Founder Mark Shuttleworth defended Unity today, arguing that even 'cool' power users should like usability and ease of use. Then again he admitted that some of us are just too cool even for Unity. 'There is going to be a crowd that is just too cool to use something that looks really slick and there is nothing we can do for them,' Shuttleworth said. 'Fortunately in Ubuntu there are tons of options and lots of choice and ways to skin the cat.'"

Shuttleworth said, 'This is a natural expansion of our idea as Ubuntu as Linux for human beings. As people have moved from desktop to new form factors for computing, it's important for us to reach out to our community on these platforms. So, we'll embrace the challenge of how to use Ubuntu on smartphones, tablets and smart-screens.'"

sfcrazy writes "Ubuntu, the world's most popular GNU/Linux based operating system is celebrating its 7th year today. Ubuntu was first released on 20 October 2004. In these 7 years Ubuntu has changed the GNU/Linux desktop segment by making it more useful for ordinary user." Besides the work that Ubuntu has done to popularize and polish the Linux desktop, and to present a humane entry point for non-guru users, it's provided a base for many other distributions (like Mint and Puppy) and helped make people realize just how powerful is the Debian infrastructure that Ubuntu itself launched from.

sfcrazy points to news, posted in the current blog post about Linux mint statistics, that the Linux Mint team "has thus decided that in the next version of Linux Mint 12, they will continue to support Gnome 2, but will also introduce Gnome 3." Related news from an anonymous reader:"Contributors in the GNOME community have started a GNOME desktop user survey. The GNOME Foundation wouldn't endorse any survey, but the community has put together a 23-question desktop survey. Regardless if you use GNOME, they encourage all Linux users to participate."

Cue the Ubuntu release parties — Ubuntu 11.10 has arrived. Ars Technica has a very positive summary of the changes in 11.10; Joe Brockmeier's piece of a few weeks back explains the return to Xen to Ubuntu and the introduction of Juju (formerly Ensemble). Asks an anonymous reader: "Any outstanding reasons why I shouldn't upgrade?" YMMV, but as a long-time Ubuntu user, and like many other users, I have mixed feelings about the concerted (and now complete) move away from a conventional WIMP interface to the new Unity. With previous versions, it was possible to choose a "classic" look rather than the default of Unity; now, for good or ill, the left-hand vertical menu is a permanent desktop element. It looks great to me, in the way the Canonical developers intend: as a consistent, replicable, supportable interface to recommend to (for instance) my parents — but I'm used to (and prefer!) more traditional WIMP environments, so at least for now have switched to Linux Mint's Debian Edition.

An anonymous reader writes "The significant Linux kernel power regression reported back in April, which ended up being attributed to PCI-E Active State Power Management, is still not resolved even as Ubuntu 11.10 and Fedora 16 approach. Until Linux is able to handle ASPM in a manner more like Windows or the device drivers explicitly set the ASPM flag, users of many modern laptops need to use the "pcie_aspm=force" option to regain much of their battery life. At least a power bug affecting newer Intel hardware with the "energy performance bias" feature has been fixed. There's more information in this LaunchPad bug report and in the latest power consumption testing."
