Official, Customized Raspberry Pi Versions Coming Soon ( 93

DeviceGuru writes: The immensely popular Raspberry Pi will soon be offered in customized versions, through an exclusive arrangement between Raspberry Pi Trading and Element14. According to the companies' announcement, Element14 will provide design and manufacturing services to OEM customers to create 'bespoke designs' based upon the Raspberry Pi technology platform. That's weird U.K. English for saying that contracts for creating customized Raspberry Pi SBCs will entail substantial NRE fees and 3,000 to 5,000 unit orders, depending on the nature of the customization. The tweaked Pi's are likely to have revised board layouts, additional or alternative functions, interfaces, connectors, and memory configurations, and more. A handful of unsanctioned Raspberry Pi knock-offs have already appeared over the past couple of years, including various Orange Pi and Banana Pi flavors, which certainly didn't involve any 'bespeaking.' More info is at Element14's CustomPi page.

ARM64 Vs ARM32 -- What's Different For Linux Programmers? ( 102

New submitter DebugN writes: When ARM introduced 64-bit support to its architecture, it aimed for Linux application compatibility with prior 32-bit software on its architecture. But for Linux programmers, there remain some significant differences that can affect code behavior. If you are a Linux programmer working with — or will soon be working with — 64-bit, you might want to know what those differences are, and this useful EDN article says it all.

22-Way SteamOS Graphics Card Comparison: NVIDIA Wins Across the Board ( 98

An anonymous reader writes: A 22-way AMD Radeon vs. NVIDIA GeForce graphics card comparison on SteamOS 2.0 "Brewmaster" was carried out with one month to go until Steam Machines begin to ship. The article looks at the OpenGL performance of this Debian-based Linux distribution as well as the power/performance efficiency, thermal efficiency, and value of the entire line-up. The results make it pretty clear why the current range of Steam Machines with SteamOS all ship with NVIDIA graphics.

Ubuntu 15.10 'Wily Werewolf' Released ( 191

LichtSpektren writes: Ubuntu 15.10 "Wily Werewolf" is now released and available, along with its alternative desktop flavors (MATE, Xfce, LXDE, GNOME, KDE, Kylin). This release features Linux 4.2, GCC 5, Python 3.5, and LibreOffice 5. The default version is still using display server and Unity7; Mark Shuttleworth has said that Mir and Unity8 won't arrive until Ubuntu 16.04 "Xenial Xerus." Not much has changed beyond package updates, other than replacing the invisible overlay scrollbars in Nautilus with the GNOME 3 scrollbars.

Phoronix brings us the only bit of drama regarding this release: Jonathan Riddell, long time overseer of Kubuntu, has resigned with claims that Canonical has "defrauded donors and broke the copyright licenses."
Another reader adds a link to a Q & A session with Riddell.

Intel Develops Linux 'Software GPU' That's ~29-51x Faster ( 111

An anonymous reader writes: Intel is open-sourcing their work on creating a high-performance graphics software rasterizer that originally was developed for scientific visualizations. Intel is planning to integrate this new OpenSWR project with Mesa to deploy it on the Linux desktop as a faster software rasterizer than what's currently available (LLVMpipe). OpenSWR should be ideal for cases where there isn't a discrete GPU available or the drivers fail to function. This software rasterizer implements OpenGL 3.2 on Intel/AMD CPUs supporting AVX(2) (Sandy Bridge / Bulldozer and newer) while being 29~51x faster than LLVMpipe and the code is MIT licensed. The code prior to being integrated in Mesa is offered on GitHub.

Report: Red Hat Buying DevOps Startup Ansible ( 78

An anonymous reader writes: According to VentureBeat Red Hat Inc is about to buy the company behind the automation and orchestration software Ansible. The move is seen as a good acquisition, since Ansible, other than being almost universally expanding, is also used by Red Hat's own cloud and system platforms. It could probably use some strong backing for the extra services it wishes to offer. The question remains whether this will have consequences in the future direction of the Python-based, open source platform itself (on GitHub). It's one of the most trivial to implement (compared to cfengine, ever-changing puppet or Chef) yet very powerful, and Red Hat may want to optimize it for their own purposes. Update: 10/16 15:39 GMT by S : Red Hat has confirmed the acquisition and explained their reasons for doing so.

Intel's Core i5 6500 Shines As a $199 Skylake Processor, Works With Linux ( 119

An anonymous reader writes: Intel has begun releasing more "Skylake" processors that are cheaper than the launch SKUs of the i5-6600K and i7-6700K. One of the new processors that is now widely available is the Core i5 6500 and it costs just $199 USD — that puts it just a few dollars more than the AMD FX-8370 and significantly less than the higher-end Skylake and Haswell CPUs. At least with Ubuntu Linux, the Core i5 6500 is showing competitive performance that for some workloads puts it faster than Core i7 Haswell/Broadwell processors and much faster than any AMD processors. The Intel Skylake CPUs are fully supported under Linux but the caveat is needing the very latest kernel otherwise there's no graphics acceleration or sound support.

KDE Turns 19 115

prisoninmate writes: Believe it or not, it has been 19 long years since Matthias Ettrich announced his new project, the Kool Desktop Environment (KDE). "Unix popularity grows thanks to the free variants, mostly Linux. But still a consistent, nice looking free desktop-environment is missing. There are several nice either free or low-priced applications available so that Linux/X11 would almost fit everybody needs if we could offer a real GUI," wrote the developer back in October 14, 1996.

Fedora 23 Final May Release As Planned On October 27 65

An anonymous reader writes: Updating a full OS distribution is no small task so it is usually no surprise that even a 5-6 month schedule may tend to get pushed back to address issues. However, the Fedora 23 release schedule made it through the Alpha, Beta and Final freeze periods so far on time. This has been accomplished despite having to address plenty of Alpha Blocker and Beta Blocker bugs. Now all that is left is to clear existing and future Final Blocker bugs in the next two weeks. The release of Fedora 23 will provide some nice incremental updates and should result in the end of life of Fedora 21 around the end of November.

Pushing the Limits of Network Traffic With Open Source ( 55

An anonymous reader writes: CloudFlare's content delivery network relies on their ability to shuffle data around. As they've scaled up, they've run into some interesting technical limits on how fast they can manage this. Last month they explained how the unmodified Linux kernel can only handle about 1 million packets per second, when easily-available NICs can manage 10 times that. So, they did what you're supposed to do when you encounter a problem with open source software: they developed a patch for the Netmap project to increase throughput. "Usually, when a network card goes into the Netmap mode, all the RX queues get disconnected from the kernel and are available to the Netmap applications. We don't want that. We want to keep most of the RX queues back in the kernel mode, and enable Netmap mode only on selected RX queues. We call this functionality: 'single RX queue mode.'" With their changes, Netmap was able to receive about 5.8 million packets per second. Their patch is currently awaiting review.

Linux Foundation: Security Problems Threaten 'Golden Age' of Open Source ( 77

Mickeycaskill writes: Jim Zemlin, executive director of the Linux Foundation, has outlined the organization's plans to improve open source security. He says failing to do so could threaten a "golden age" which has created billion dollar companies and seen Microsoft, Apple, and others embrace open technologies. Not long ago, the organization launched the Core Infrastructure Initiative (CII), a body backed by 20 major IT firms, and is investing millions of dollars in grants, tools, and other support for open source projects that have been underfunded. This was never move obvious than following the discovery of the Heartbleed Open SSL bug last year. "Almost the entirety of the internet is entirely reliant on open source software," Zemlin said. "We've reached a golden age of open source. Virtually every technology and product and service is created using open source. Heartbleed literally broke the security of the Internet. Over a long period of time, whether we knew it or not, we became dependent on open source for the security and Integrity of the internet."

Linus: '2016 Will Be the Year of the ARM Laptop' ( 182

jones_supa writes: Linus Torvalds took the stage at LinuxCon Europe in Dublin, Ireland, and talked about a number of things, including security and the future for Linux on ARM hardware. There is nothing that will blow your mind, but there are a couple of interesting statements nonetheless. Chromebooks are slowly taking over the world, and a large number of those Chromebooks are powered by ARM processors. "I'm happy to see that ARM is making progress. One of these days, I will actually have a machine with ARM. They said it would be this year, but maybe it'll be next year. 2016 will be the year of the ARM laptop," said Linus excitedly. He also explained that one of the problems now is actually finding people to maintain Linux. It's not a glorious job, and it usually entails answering emails seven days a week. Finding someone with the proper set of skills and the time to do this job is difficult.

Debian Dropping Linux Standard Base ( 220

basscomm writes: For years (as seen on Slashdot) the Linux Standard Base has been developed as an attempt to reduce the differences between Linux distributions in an effort significant effort. However, Debian Linux has announced that they are dropping support for the Linux Standard Base due to a lack of interest.

From the article: "If [Raboud's] initial comments about lack of interest in LSB were not evidence enough, a full three months then went by with no one offering any support for maintaining the LSB-compliance packages and two terse votes in favor of dropping them. Consequently, on September 17, Raboud announced that he had gutted the src:lsb package (leaving just lsb-base and lsb-release as described) and uploaded it to the "unstable" archive. That minimalist set of tools will allow an interested user to start up the next Debian release and query whether or not it is LSB-compliant—and the answer will be 'no.'"


Ubuntu Plans To Make ZFS File-System Support Standard On Linux 279

An anonymous reader writes: Canonical's Mark Shuttleworth revealed today that they're planning to make ZFS standard on Ubuntu. They are planning to include ZFS file-system as "standard in due course," but no details were revealed beyond that. However, ZFS On Linux contributor Richard Yao has said they do plan on including it in their kernel for 16.04 LTS and the GPL vs. CDDL license worries aren't actually a problem. Many Linux users have been wanting ZFS on Linux, but aside from the out of tree module there hasn't been any luck in including it in the mainline kernel or with tier-one Linux distributions due to license differences.

Matthew Garrett Forks the Linux Kernel 688

jones_supa writes: Just like Sarah Sharp, Linux developer Matthew Garrett has gotten fed up with the unprofessional development culture surrounding the kernel. "I remember having to deal with interminable arguments over the naming of an interface because Linus has an undying hatred of BSD securelevel, or having my name forever associated with the deepthroating of Microsoft because Linus couldn't be bothered asking questions about the reasoning behind a design before trashing it," Garrett writes. He has chosen to go his own way, and has forked the Linux kernel and added patches that implement a BSD-style securelevel interface. Over time it is expected to pick up some of the power management code that Garrett is working on, and we shall see where it goes from there.

Linux Kernel Dev Sarah Sharp Quits, Citing 'Brutal' Communications Style 928

JG0LD writes: A prominent Linux kernel developer announced today in a blog post that she would step down from her direct work in the kernel community. “My current work on userspace graphics enabling may require me to send an occasional quirks kernel patch, but I know I will spend at least a day dreading the potential toxic background radiation of interacting with the kernel community before I send anything,” Sharp wrote. Back in July, 2013 Sarah made a push to make the Linux Kernel Development Mailing List a more civil place.

Vigilante Malware Protects Routers Against Other Security Threats 79

Mickeycaskill writes: Researchers at Symantec have documented a piece of malware that infects routers and other connected devices, but instead of harming them, improves their security. Affected routers connect to a peer-to-peer network with other compromised devices, to distribute threat updates. 'Linux.Wifatch' makes no attempt to conceal itself and even left messages for users, urging them to change their passwords and update their firmware. Symantec estimates 'tens of thousands' of devices are affected and warns that despite Wifatch's seemingly philanthropic intentions, it should be treated with caution.

"It should be made clear that Linux.Wifatch is a piece of code that infects a device without user consent and in that regard is the same as any other piece of malware," said Symantec. "It should also be pointed out that Wifatch contains a number of general-purpose back doors that can be used by the author to carry out potentially malicious actions." There is one simple solution to rid yourself of the malware though: reset your device

Linux Foundation Puts the Cost of Replacing Its Open Source Projects At $5 Billion 146

chicksdaddy writes: Everybody recognizes that open source software incredibly valuable, by providing a way to streamline the creation of new applications and services. But how valuable, exactly? The Linux Foundation has released a new research paper that tries to put a price tag on the value of the open source projects it comprises, and the price they've come up with is eye-popping: $5 billion. That's how much the Foundation believes it would cost for companies to have to rebuild or develop from scratch the software residing in its collaborative projects.

To arrive at that figure, the Foundation analyzed the code repositories of each one of its projects using the Constructive Cost Model (COCOMO) to estimate the total effort required to create these projects. With 115,013,302 total lines of source code, LF estimated the total amount of effort required to retrace the steps of collaborative development to be 41,192.25 person-years — or 1,356 developers 30 years to recreate the code base present in The Linux Foundation's current collaborative projects listed above.

What's New In GNOME 3.18 170

prisoninmate writes: In this release, GNOME improves the general user experience for users and new developers alike. GNOME 3.18 adds a feature called "Automatic Brightness," which, when enabled, it will make use of your laptop's light sensor to dim or increase the screen's brightness depending on the surrounding lighting. GNOME 3.18 also improves the touch screen experience, especially when selecting and modifying text, implements a new view in the Nautilus (Files) sidebar, which collects all the remote and internal locations in a single place.

Ask Slashdot: Recommendations For a Reliable Linux Laptop? 237

An anonymous reader writes: I will be looking for a new laptop soon and I'm mostly interested in high reliability and Linux friendliness. I have been using an MSI laptop (with Windows 7) for the last five years as my main workhorse and did not have a single, even minor problem with the hardware nor the OS. It turned out to be a slam-dunk, although I didn't do any particular research before buying it, so I was just lucky. I would like to be more careful this time around, so this is a hardware question: What laptop do you recommend for high reliability with Linux? I will also appreciate any advice on what to avoid and any unfortunate horror stories; I guess we can all learn from those. Anti-recommendations are probably just as valuable, a lesson I learned when an HP laptop I bought (low-end, I admit) turned out to be notoriously fickle when it comes to Linux support. Since our anonymous submitter doesn't specify his budget, it would be good if you specify the price for any specific laptops you recommend.
