High School Students Develop Linux Imaging and Help Desk Software 116

An anonymous reader writes "A Pennsylvania school district is going Linux and building an open source high school with the help of student technology apprentices. As part of a 1:1 laptop learning program, 1725 high school students at Penn Manor School District are receiving new laptops running Ubuntu and open source software exclusively. Central to the program is a student help desk where student programmers created a Linux multicast imaging system titled Fast Linux Deployment Toolkit. The district posted pictures of the imaging process in action. Working alongside school IT staff, students also developed help desk software and other programs in support of the 1:1 student laptop program. The student tech apprentices also provide peer support for fellow students."

Linus Torvalds: Any CLA Is Fundamentally Broken 279

sfcrazy writes "The controversy over Canonical's Contributor License Agreement (CLA) has once again surfaced. While Matthew Garrett raises valid points about the flaws in Canonical's CLAs, Linus Torvalds says 'To be fair, people just like hating on Canonical. The FSF and Apache Foundation CLA's are pretty much equally broken. And they may not be broken because of any relicencing, but because the copyright assignment paperwork ends up basically killing the community. Basically, with a CLA, you don't get the kind of "long tail" that the kernel has of random drive-by patches. And since that's how lots of people try the waters, any CLA at all – changing the license or not – is fundamentally broken.'"

Valve Working on GNU/Linux Native Open Source OpenGL Debugger 88

jones_supa writes "OpenGL debugging has always lagged behind DirectX, mainly because of the excellent DX graphics debugging tools shipping with Visual Studio and GL being left with APITrace. Valve's Linux initiatives are making game companies to think about OpenGL, and the video game company wants to create a good open source OpenGL debugger to improve the ecosystem. AMD and Nvidia have already expressed interest in helping them out. Valve has been developing VOGL mostly on Ubuntu-based distributions under Qt Creator. The software currently supports tracing OpenGL 1.0 through 3.3 (core and compatibility), and is expected to eventually support OpenGL 4.x. Many more details on VOGL can be found at Valve's Rich Geldreich's blog." This looks much nicer than BuGLe. Valve is using Mercurial for version control and they plan to throw it up on bitbucket under an unspecified open source license soon. It works with clang and gcc, but debugging with gcc is currently very slow (hopefully something that can be fixed once the source is available and the gcc hackers can see what's going on). The tracer's internal binary log format can be converted into JSON for use with other tools as well.

If UNIX Were a Religion 392

Hugh Pickens DOT Com writes "Charles Stross has written a very clever article where he describes the religious metaphor he uses with non-technical folks to explain the relationship between Mac OS X and UNIX. There is one true religion in operating systems says Stross and it is UNIX although there's also an earlier, older, more arcane religion with far fewer followers, MULTICS, from which UNIX sprang as a stripped-down rules-deficient heresy. If MULTICS is Judaism then UNIX is Christianity. By the mid-1970s there were two main sects: AT&T UNIX, which we may liken unto the Roman Catholic Church, and BSD UNIX, which we may approximate to the Orthodox Churches. In an attempt to control the schisms, the faithful defined a common interoperating subset of the one true religion that all could agree on—the Nicene Creed of UNIX which is probably POSIX. Stross says that today the biggest church in the whole of UNIX is Mac OS X, which rests on the bedrock of Orthodox BSD but "has added an incredible, towering superstructure of fiercely guarded APIs and proprietary user interface stuff that renders it all but unrecognizable to followers of the Catholic AT&T path." But lo, in the late 1980s, UNIX succumbed to the sins of venality, demanding too much money from the faithful and so, in 1991 Linus Torvalds nailed his famous source code release to the cathedral door and kicked off the Reformation. 'The Linux wars were brutal and unforgiving and Linux itself splintered into a myriad of fractious Protestant churches, from the Red Hat wearing Lutherans to the Ubuntu Baptists.' More recently, a deviant faith has sprung from Linux. 'Android is the Church of Latter Day Saints of UNIX: hard-working, sober, evangelizing the public, and growing at a ferocious rate. There are some strange fundamentalist Mormon Android churches living in walled communities under the banners of Samsung and Amazon, but for the most part the prosperous worship at the Church of Google.' Stross notes that as with all religion, those sects with most in common are the ones who hold the most vicious grudges against one another. 'Is that clear?'"

Ask Slashdot: Will You Start Your Kids On Classic Games Or Newer Games? 285

An anonymous reader writes "An article at The Verge got me thinking. Parents and those of you who plan to become parents: will you introduce your kids to the games you played when you were younger? Those of us who grew up playing Pong, Space Invaders, and Pac-Man have had a chance to see gaming software evolve into the enormously complex and graphically realistic beast it is today. I've begun to understand why my grandparents tried to get me to watch old movies. I'm also curious how you folks plan to teach your kids about computers and software in general. When teaching them Linux, do you just download the latest stable Mint or Ubuntu release and let them take it from there? Do you track down a 20-year-old version of Slackware and show them how things used to be? I can see how there would be value in that... the UIs we use every day have been abstracted so far away from their roots that we can't always expect new users to intuitively grasp the chain of logic. How do you think this should be handled?"

Linux x32 ABI Not Catching Wind 262

jones_supa writes "The x32 ABI for Linux allows the OS to take full advantage of an x86-64 CPU while using 32-bit pointers and thus avoiding the overhead of 64-bit pointers. Though the x32 ABI limits the program to a virtual address space of 4GB, it also decreases the memory footprint of the program and in some cases can allow it to run faster. The ABI has been talked about since 2011 and there's been mainline support since 2012. x32 support within other programs has also trickled in. Despite this, there still seems to be no widespread interest. x32 support landed in Ubuntu 13.04, but no software packages were released. In 2012 we also saw some x32 support out of Gentoo and some Debian x32 packages. Besides the kernel support, we also saw last year the support for the x32 Linux ABI land in Glibc 2.16 and GDB 7.5. The only Linux x32 ABI news Phoronix had to report on in 2013 was of Google wanting mainline LLVM x32 support and other LLVM project x32 patches. The GCC 4.8.0 release this year also improved the situation for x32. Some people don't see the ABI as being worthwhile when it still requires 64-bit processors and the performance benefits aren't very convincing for all workloads to make maintaining an extra ABI worthwhile. Would you find the x32 ABI useful?"

Free Software Foundation Endorses a "Truly Free" Laptop 340

An anonymous reader writes "The Free Software Foundation announced today the first laptop they have been able to certify as-is that respects the user's freedoms. The laptop is free down to using Coreboot in place of a proprietary BIOS. The OS shipped on the laptop is Trisquel, the Ubuntu derived Linux OS that removes all traces of proprietary firmware, patented formats, etc. The only issue though for new customers is this endorsed laptop comes down to being a refurbished 2006 ThinkPad X60 with single or dual-core Intel CPU, 1GB+ of RAM, 60GB+ HDD, and a 1024x768 12.1-inch screen, while costing $320+ USD (200 GBP). The FSF-certified refurbished laptops are only offered for sale through the Gluglug UK shop. Are these outdated specs worth your privacy and freedom?"

Fedora 20 Released 147

sfcrazy writes "The Fedora Project has announced the release of Fedora 20, code named Heisenbug (release notes). Fedora 20 is dedicated to Seth Vidal, the lead developer of Yum and the Fedora update repository, who recently died in a road accident. Gnome is the default DE of Fedora, and so it is for Fedora 20. However unlike Ubuntu (where they had to create different distros for each DE) Fedora comes with KDE, XFCE, LXDE and MATE. You can install the DE of your choice on top of base Fedora."

Canonical Moving Away From GNOME Control Center 208

jones_supa writes "This announcement comes from the ubuntu-desktop mailing list. Due to GNOME Control Center already being a heavily patched version in Ubuntu, Canonical is planning to found their own fork called Unity Control Center. This would be a fork with a limited lifespan and later on they would move to something called Ubuntu System Settings, an in-house project. For now, a PPA has been set up to test the new fork."

The Burning Bridges of Ubuntu 346

jammag writes "According to this article, 'Whether Ubuntu is declining is still debatable. However, in the last couple of months, one thing is clear: internally and externally, its commercial arm Canonical appears to be throwing the idea of community overboard as though it was ballast in a balloon about to crash.' The author points out instances of community discontent and apparent ham-handedness on Mark Shuttleworth's part. Yet isn't this just routine kvetching in the open source community?"

Docker 0.7 Runs On All Linux Distributions 88

rjmarvin writes "Docker 0.7 was released today, with 7 major new features including support to run on all Linux distributions. No longer capable solely on running on Debian and Ubuntu Linux, Docker 0.7 adds support for distributions such as Red Hat, SUSE, Gentoo and Arch. From the announcement: 'A key feature of Docker is the ability to create many copies of the same base filesystem almost instantly. Under the hood Docker makes heavy use of AUFS by Junjiro R. Okajima as a copy-on-write storage mechanism. AUFS is an amazing piece of software and at this point it’s safe to say that it has safely copied billions of containers over the last few years, a great many of them in critical production environments. Unfortunately, AUFS is not part of the standard linux kernel and it’s unclear when it will be merged. This has prevented docker from being available on all Linux systems. Docker 0.7 solves this problem by introducing a storage driver API, and shipping with several drivers. Currently 3 drivers are available: AUFS, VFS (which uses simple directories and copy) and DEVICEMAPPER, developed in collaboration with Alex Larsson and the talented team at Red Hat, which uses an advanced variation of LVM snapshots to implement copy-on-write. An experimental BTRFS driver is also being developed, with even more coming soon: ZFS, Gluster, Ceph, etc. When the docker daemon is started it will automatically select a suitable driver depending on its capabilities.'"

Mir Won't Ship Even In Ubuntu 14.04 111

jones_supa writes "As can be recalled, Mir didn't make it to the Ubuntu 13.10 release to replace X.org as the display server. Back then it suffered of problems in multi-monitor support, along with other issues. Now it turns out that Canonical's product will not make it even into the next LTS version (14.04) of the Ubuntu desktop. Mir itself would be ready for showtime in the schedule, but there are problems with XMir, which is the X11 compatibility layer that ensures Mir can work with applications built for X. The comments came at the Ubuntu Developer Summit: in an online event Mark Shuttleworth stressed that the 14.04 desktop has to be rock-solid for customers with large-scale deployments, such as educational institutions. In the meantime, you can already try out Mir in your Ubuntu system."

OpenSUSE 13.1 Released and Reviewed 113

sfcrazy writes "The openSUSE team just announced the release of openSUSE 13.1. There are some core points which set openSUSE apart from the popular Ubuntu distro. While Ubuntu has become a more or less Canonical-owned project, openSUSE is becoming more and more community-driven. Looking at the recent controversies around Ubuntu and their move toward mobile platforms, openSUSE seems to be a great option for desktop users."

Ubuntu Wants To Enable SSD TRIM By Default 135

jones_supa writes "During the first day of the latest virtual Ubuntu Developer Summit, Canonical developers finally plotted out the enabling of TRIM/DISCARD support by default for solid-state drives on Ubuntu 14.04. Ubuntu developers aren't looking to enable discard at the file-system level since it can slow down delete operations, so instead they're wanting to have their own cron job that routinely runs fstrim for TRIMing the system. In the past there has been talk about the TRIM implementation being unoptimized in the kernel. Around when Linux 3.0 was released, OpenSUSE noted that the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance."

Canonical Developer Warns About Banking With Linux Mint 206

sfcrazy writes "Ubuntu developer Oliver Grawert does not prefer to do online banking with Linux Mint. In the official mailing list of the distribution, Ubuntu developers stated that the popular Ubuntu derivative is a vulnerable system and people shouldn't go for online banking on it. One of the Ubuntu developers, Oliver Grawert, originally pointed out that it is not necessary that security updates from Ubuntu get down to Linux Mint users since changes from X.Org, the kernel, Firefox, the boot-loader, and other core components are blocked from being automatically upgraded." Clement Lefebvre, the Linux Mint project founder, has since made a statement and confirmed that Oliver Grawert seems "more opinionated than knowledgeable" adding "the press blew what he said out of proportion."

Dell's New Sputnik 3 Mates Touchscreen With Ubuntu 166

ClaraBow writes "I find it interesting that Dell has started selling a thin and light touchscreen laptop called the XPS 13 Developer Edition, which will have Ubuntu Linux OS and Intel's fourth-generation Core processors, code-named Haswell. The laptop, code-named Sputnik, has a 13.3-inch touchscreen and will run on Ubuntu 12.04 OS. It is priced starting at $1,250 and is available in the U.S." One thing I wish was addressed in the blog post announcing this newest entry in the Sputnik line, or its listed specs (bad news beats not knowing, in this case), is battery life.

EFF Says Mark Shuttleworth Is Wrong About Trademark 103

sfcrazy writes "Last week Canonical sent a cease and desist letter to EFF staffer Micah F Lee asking him to remove the word Ubuntu from the URL as well as the Ubuntu logo from the site. Lee responded through an attorney who said that Canonical's 'request were not supported by trademark laws and interferes with protected speech.' Shuttleworth apologized, though it was cheeky, and while he dubbed the Mir opponents as non-technical (hello KDE, systemD, Wayland, Intel) he also went on to explain why they needed to protect their trademark. Now there is an official response from EFF. In the blog post EFF has explained that Shuttleworth is far from reality and was totally wrong about trademark."

Mark Shuttleworth Apologizes for Trademark Action Against Fix Ubuntu 196

A few days ago, the operator of Fix Ubuntu received a threatening letter from Canonical commanding him to cease using the Ubuntu name or logo. Last night, Mark Shuttleworth posted an update noting that it shouldn't have happened, and also apologizing for calling opponents of Mir the open source tea party. "In order to make the amount of [trademark related] correspondence manageable, we have a range of standard templates for correspondence. They range from the 'we see you, what you are doing is fine, here is a license to use the name and logo which you need to have, no need for further correspondence,' through 'please make sure you state you are speaking for yourself and not on behalf of the company or the product,' to the 'please do not use the logo without permission, which we are not granting unless you actually certify those machines,' and 'please do not use Ubuntu in that domain to pretend you are part of the project when you are not.' Last week, the less-than-a-month-at-Canonical new guy sent out the toughest template letter to the folks behind a “sucks” site. Now, that was not a decision based on policy or guidance; as I said, Canonical’s trademark policy is unusually generous relative to corporate norms in explicitly allowing for this sort of usage. It was a mistake, and there is no question that the various people in the line of responsibility know and agree that it was a mistake. It was no different, however, than a bug in a line of code, which I think most developers would agree happens to the best of us. It just happened to be, in that analogy, a zero-day remote root bug. ... On another, more personal note, I made a mistake myself when I used the label “open source tea party” to refer to the vocal non-technical critics of work that Canonical does. That was unnecessary and quite possibly equally offensive to members of the real Tea Party (hi there!) and the people with vocal non-technical criticism of work that Canonical does (hello there!)."

Canonical Targets Ubuntu Privacy Critic 259

New submitter bkerensa writes "A member of Canonical's Legal Team recently sent a email to a critic of Ubuntu's privacy settings to insist he stop using the Ubuntu name and logo, even though it falls under 'fair use.' Micah Lee is the CTO of the Freedom of the Press Foundation and maintainer of the HTTPS Everywhere project. When Ubuntu began adding commercial results in its Dash search software, Lee wrote about the privacy concerns and created a site called Fix Ubuntu to show people how to turn it off. Canonical's legal department has now sent him a letter asking him to 'remove [the] Ubuntu word from you[r] domain name and Ubuntu logo from your website.'"
