Linux Kernel Patch Hints At At 32-Core Support For AMD Zen Chips 127

New submitter Iamthecheese points to an article which says that a patch published on the Linux Kernel Mailing List indicates that AMD's forthcoming Zen processors will have as many as 32 cores per socket, but notes that while the article's headline says "Confirms," "the article text doesn't bear that out." Still, he writes, There are hints of such from last year. A leaked patch for the 14 nanometer AMD Zeppelin (Family 17h, Model 00h) reveals support for up to 32 cores. Another blog says pretty much the same thing. We recently discussed an announced 4+8 core AMD chip, but nothing like this.

Docker Images To Be Based On Alpine Linux (brianchristner.io) 82

New submitter Tenebrousedge writes: Docker container sizes continue a race to the bottom with a couple of environments weighing in at less than 10MB. Following on the heels of this week's story regarding small images based on Alpine Linux, it appears that the official Docker images will be moving from Debian/Ubuntu to Alpine Linux in the near future. How low will they go?

The Performance of Ubuntu Linux Over the Past 10 Years (phoronix.com) 109

An anonymous reader writes: Tests were carried out at Phoronix of all Ubuntu Long-Term Support releases from the 6.06 "Dapper Drake" release to 16.04 "Xenial Xerus," looking at the long-term performance of (Ubuntu) Linux using a dual-socket AMD Opteron server. Their benchmarks of Ubuntu's LTS releases over 10 years found that the Radeon graphics performance improved substantially, the disk performance was similar while taking into account the switch from EXT3 to EXT4, and that the CPU performance had overall improved for many workloads thanks to the continued evolution of the GCC compiler.

CFQ In Linux Gets BFQ Characteristics 65

jones_supa writes: Paolo Valente from University of Modena has submitted a Linux kernel patchset which replaces CFQ (Completely Fair Queueing) I/O scheduler with the last version of BFQ (Budget Fair Queuing, a proportional-share scheduler). This patchset first brings CFQ back to its state at the time when BFQ was forked from CFQ. Paolo explains: "Basically, this reduces CFQ to its engine, by removing every heuristic and improvement that has nothing to do with any heuristic or improvement in BFQ, and every heuristic and improvement whose goal is achieved in a different way in BFQ. Then, the second part of the patchset starts by replacing CFQ's engine with BFQ's engine, and goes on by adding current BFQ improvements and extra heuristics." He provides a link to the thread in which it is agreed on this idea, and a direct link to the e-mail describing the steps.

CoreOS Launches Rkt 1.0 (eweek.com) 49

darthcamaro writes: Docker is about to get some real competition in the container runtime space, thanks to the lofficial aunch of rkt 1.0. CoreOS started building rkt in 2014 and after more than a year of security, performance and feature improvement are now ready to declare it 'production-ready.' While rkt is a docker runtime rival, docker apps will run in rkt, giving using a new runtime choice: "rkt will remain compatible with the Docker-specific image format, as well as its own native App Container Image (ACI). That means developers can build containers with Docker and run those containers with rkt. In addition, CoreOS will support the growing ecosystem of tools based around the ACI format."

Interviews: Ask 'Ubuntu Unleashed' Author Matthew Helmke 58

Matthew Helmke (personal blog) is the author of the newly published 11th edition of Ubuntu Unleashed (published by Pearson); this updated edition of the book will cover the OS through Ubuntu's 15.10 and (forthcoming) 16.04 releases. Helmke is also a former Ubuntu Forum administrator, a musician, an entrepreneur, and a long-time Slashdot reader who now leads a "nice quiet life in Iowa." Ask Matthew about what it's like to be a Linux book author and community leader, and his thoughts on Canonical, the goods and bads of modern Linux distributions, and the future of Ubuntu -- especially relevant with the upcoming release of the first Ubuntu-based tablet. (Remember, Matthew isn't responsible for gripes you may have with either Ubuntu or Canonical, but he might have some good solutions to particular problems.) Ask as many questions as you'd like; we just ask that you keep them on-topic, and please stick to one question per post.

Canonical Reveals the BQ Aquaris M10 Ubuntu Tablet (omgubuntu.co.uk) 92

LichtSpektren writes: Several tech sites have now broke the news that Canonical has revealed their BQ Aquaris M10 Ubuntu Tablet. Joey-Elijah Sneddon builds the hype: "A stunning 10.1-inch IPS touch display powered a full HD 1920×1200 pixel resolution at 240 ppi. Inside is a 64-bit MediaTek MT8163A 1.5GHz quad-core processor, 2GB of RAM, and 16GB of internal memory. A micro SD memory card is included, adding storage expansion of up to 64GB. Furthermore, the converged slate includes an 8-megapixel rear camera with autofocus and dual LED flash (and capable of recording in full 1080p), plus a front facing 3-megapixel camera for video chats, vlogs and selfies. Front facing Dolby Atmos speakers will provide a superior sound experience during movie playback. The M10 measure 246mm x 171mm x 8.2mm, weighs just 470 grams — lighter than the Apple iPad Air — and has a 7280 mAh battery to give up to 10 hours of use. ... Tablet mode offers a side stage for running two apps side-by-side, plus a full range of legacy desktop applications, mobile apps and scopes. LibreOffice, Mozilla Firefox, The GIMP and Gedit are among a 'curated collection of legacy apps' to ship pre-installed on the tablet. It will also be possible for developers and enthusiasts to install virtually any ARM compatible app available on Ubuntu using the familiar 'apt-get' command." A photo gallery can also be seen on his website here. The price is not yet announced, but the Android version of the same tablet is currently on sale for €229.

Running "rm -rf /" Is Now Bricking Linux Systems (phoronix.com) 698

An anonymous reader writes: For newer systems utilizing UEFI, running rm -rf / is enough to permanently brick your system. While it's a trivial command to run on Linux systems, Windows and other operating systems are also prone to this issue when using UEFI. The problem comes down to UEFI variables being mounted with read/write permissions and when recursively deleting everything, the UEFI variables get wiped too. Systemd developers have rejected mounting the EFI variables as read-only, since there are valid use-cases for writing to them. Mounting them read-only can also break other applications, so for now there is no good solution to avoid potentially bricking your system, but kernel developers are investigating the issue.

Linux Kernel 2.6.32 LTS Reaches End of Life In February 2016 (softpedia.com) 116

An anonymous reader writes: The oldest long-term supported Linux kernel branch finally reaches end of life next month, but before going into the deepest darkest corners of the Internet, it just dropped one more maintenance release, Linux kernel 2.6.32.70 LTS. Willy Tarreau dropped the news about the release of Linux kernel 2.6.32.70 LTS on January 29, 2016, informing all us that this will most likely be the last maintenance release in the series, as starting with February 2016 it will no longer be supported with security patches and bugfixes. Linux 2.6 first came out in December, 2003, and 2.6.16 (the first long-term release) in March 2006.

Project Neon Will Bring Users Up-to-Date KDE Packages (cio.com) 42

sfcrazy writes: [Kubuntu founder Jonathan Riddell] is going to announce a new project at FOSDEM that brings the KDE experience to users. There is Fedora that offers latest from Gnome, but there is no such distro that offers the same level of integration with KDE software; yes, there is openSUSE but it offers KDE as an option. So Kubuntu based KDE Neon is a project to give KDE users and contributors a way to get KDE's desktop software while it's still fresh. It'll be providing packages of the latest KDE software so users can install it and stay up to date on a stable base.

Intel Gets Called Out Again For Their M.I.A. 3.0 X.Org Driver (phoronix.com) 110

An anonymous reader writes: The xf86-video-intel 3.0 DDX driver has been in development the past two and a half years without seeing an official release. The last development release even of xf86-video-intel 3.0 Git was 13 months ago with the xf86-video-intel 2.99.917 release. At that time it was said by Intel's lead DDX developer, "3 months have passed, we should make one more snapshot before an imminent release." Since then, there's been no communications about a stable release of this DDX driver that makes SNA the default acceleration architecture over UXA. Over on the intel-gfx mailing list users are bringing up again the state of xf86-video-intel 3.0 and why it isn't released yet, questioning if Intel is "able to maintain its own device driver in a usable way?"

The US Government and Open Standards: a Tale of Personal Woe (thevarguy.com) 256

An anonymous reader writes: This article details a Linux user's struggles to submit a grant application when the process requires finicky, proprietary software. It also covers familiar ground made timely by the upcoming elections: the U.S. should prefer open source software and open standards over proprietary alternatives. The grant application required a PDF created by Adobe Acrobat — software Adobe no longer supports for Linux. Once the document was created, attempting to submit it while using Ubuntu fails silently. (On Windows 7, it worked immediately.) The reader argues, "By requiring Acrobat the government gives preference to a particular software vendor, assuring that thousands of people who otherwise would not choose to use Adobe software are forced to install it. Worse, endorsing a proprietary, narrowly supported technology for government data poses the risk that public information could become inaccessible if the vendor decides to stop supporting the software. Last but not least, there are privacy and fairness issues at stake. Acrobat is a totally closed-source program, which means we have to take Adobe's word for it that nothing sketchy is going on in its code. ... It would seem to be in the interest of the public for the government to prefer an open source solution, since it is much harder to hide nefarious features inside code that can be publicly inspected."

Docker Moves Beyond Containers With Unikernel Systems Purchase (thenewstack.io) 69

joabj writes: Earlier today, Docker announced that it had purchased the Cambridge, U.K.-based Unikernel Systems, makers of the OCaml-based MirageOS, a unikernel or "virtual library-based operating system." Unikernels go beyond containers in stripping virtualization down to the bare essentials in that they only include the specific OS functionality that the application actually needs. Their design builds on decades of research into modular OS design. Although unikernels can be complex to deploy for developers, Docker aims to make the process as standardized as possible, for easier deployment.
