  • Linspire 7.0.1 and Freespire 3.0.1 Released - Meltdown and Spectre fix

    This morning we have released Linspire 7.0.1 and Freespire 3.0.1 . With this release we have addressed the Meltdown and Spectre vulnerabilities in Intel Processors. We have included no new features.

  • Black Lab Enterprise Linux 11.51 Released - Meltdown and Spectre Fix

    Today we have released Black Lab Enterprise Linux 11.51. This release addresses the Meltdown and Spectre vulnerabilities in Intel Processors. We have included no new features. To apply the fix simply run your system updater and the fix will be applied.

    This update has been thoroughly tested and does not cause any issues or malfunctions

  • At CES, Spectre haunted tech executives in public and private meetings

    Despite being drenched and briefly thrust in to darkness, the largest annoyance for many top tech executives at CES was the shadow of Spectre.

    The world’s largest electronics show immediately careened toward the twin maladies dubbed Spectre and Meltdown, potentially exploitable weaknesses in the brains of PCs and servers world-wide.

Linux 4.15 RC8 and Linux Kernel Mailing List Downtime

Filed under
Linux
  • Linux 4.15-rc8

    Ok, another week has gone by, and here's the promised rc8.

    I'm still hoping that this will be the last rc, despite all the
    Meltdown and Spectre hoopla. But we will just have to see, it
    obviously requires this upcoming week to not come with any huge
    surprises.

    The patches aren't huge, but architecture updates do end up being a
    largish part. That's partly due to the x86 "retpoline" support (well,
    the basic stuff that is uncontested), but also because the powerpc
    people decided they wanted to play too, so there's some low-level
    kernel entry changes there too. Aren't we lucky?

    Oh, and there's a small RISC-V update too.

    But outside of that, we've got driver updates (gpu, networking, usb,
    sound, NVMe), some core networking, and some tooling updates (mostly a
    few new x86 selftests). And some random misc fixlets (documentation,
    apparmor, crypto).

    Go forth and test. It all looks pretty solid to me,

    Linus

  • Kernel prepatch 4.15-rc8

    The 4.15-rc8 kernel prepatch is out for testing. Among other things, it includes the "retpoline" mechanism intended to mitigate variant 2 of the Spectre vulnerability. Testing of this change will be hard, though, since it requires a version of GCC that almost nobody has — watch LWN for a full article in the near future.

  • Linux 4.15-rc8 Released As The Last Before Final

    LINUX KERNEL --
    Linus Torvalds has released Linux 4.15-rc8 as the last planned release candidate prior to officially debuting Linux 4.15 next weekend.

    Linux 4.15-rc8 brings some BPF security improvements in the wake of the Spectre CPU vulnerabilities and there is the other smothering of bug/regression fixes too with this weekly Linux 4.15 release candidate.

  • An Incident Worth Noticing: Linux Kernel Mailing List Website Goes Down for Days

    Reality: the website goes down because it is hosted on a home server that suffered a power outage and needed the password to boot. Problem was that owner Jasper was on vacation when this incident happened.

Filed under
Gaming
  • Introducing the CAPS0ff Project

    It's no secret that I love classic video games. Fortunately, thanks to emulation, many of the classic arcade games still can be enjoyed and forever will be available via digital copies of the ROM chips. Sadly, some older systems have protection, making them impossible to dump into ROMs properly. If the chips can't be dumped, how will you ever get a digital copy of the ROM data? Well, the folks over at the CAPS0ff blog actually are disassembling the original chips and painstakingly transcribing the contents one bit at a time. They're literally looking at the chips and determining the 1s and 0s burned onto them.

  • Godot 3.0 Release Candidate 1 Debuts Ahead Of This Imminent Game Engine Release

    The crew responsible for the open-source Godot cross-platform game engine have announced the 3.0 Release Candidate ahead of the imminent stable release of this major update.

  • Dev snapshot: Godot 3.0 RC 1

    So Godot 3.0 won't be a 2017 release as we had hoped during the last semester, but we are pretty confident that you will get it in January 2018 to properly kickstart this new year!

    We fixed hundreds of bugs and declared the release freeze, which means that many non critical bugs and enhancements have been moved to the 3.1 milestone, allowing us to tend faster towards the final 3.0 release by focusing on the big issues.

  • Playing Quake 4 on Linux in 2018

    A few months back I wrote an article outlining the various options Linux users now have for playing Doom 3, as well as stating which of the three contenders I felt to be the best option in 2017. Having already gone to the trouble of getting the original Doom 3 binary working on my modern Arch Linux system, it made me wonder just how much effort it would take to get the closed source Quake 4 port up and running again as well.

  • Looks like the sci-fi narrative exploration game Event[0] may still be coming to Linux

    I know a fair few people were upset by the silence surrounding the previously promised Linux version of Event[0]. It looks like it might still be happening.

    As of a few hours ago, it seems the developer added a Linux content depot, so it seems like they might actually be working on it now. Either that, or it took some time to get it into a state where they could get something up on Steam. I will keep a close on eye on it and let you know of any changes in regards to an actual release.

  • Cold Space, a fast-paced one-shot kill FPS has Linux support

    A rather interesting looking fast-paced FPS released with Linux support recently called Cold Space [Steam, Official Site], I took a look to see if it's any good.

    The Linux build released only a few days ago, not long after the Windows version. The initial announcement said it was only for NVIDIA, but it seems it may work on AMD GPUs now too as it's listed in the system requirements.

  • Tale of Toast, another open world MMO that's going to release with Linux support

    Tale of Toast [Official Site, Steam] is another MMO that will release with Linux support, it will be free to play without any pay to win apparently.

    It will have no classes, open world PvP combat with a zone system that sounds like it might be similar to Albion Online and they're focusing on "quality before quantity" when it comes to the quests that will be available.

  • Some Of What's Coming For Wayland's Weston 4.0 Compositor

    Earlier this week ongoing Wayland/Weston release manager Bryce Harrington at Samsung laid out plans for Wayland 1.15 and Weston 4.0. There's been some push-back on the proposed dates to try to allow some more work to land in these upcoming six month releases to Wayland/Weston, but long story short, these next releases will be here in the near future.

    With Wayland itself quite mature, there isn't much that's exciting for end-users about Wayland 1.15. In fact, not many changes at all unless there's a last-minute rush of new work to land. As is the case these days, most of the interesting work is happening within the Weston compositor space as developers flesh out new functionality and prototype features that will hopefully be picked up by the other Wayland compositors that are becoming widely used on the Linux desktop.

  • Linux Graphics Trends Over The Past Five Years

    Yesterday I posted some Linux hardware statistics going back to 2011 using data collected by the Phoronix Test Suite and OpenBenchmarking.org. Those yearly metrics hadn't contained any GPU/driver data, but here are those numbers.

    The graphics numbers were omitted from yesterday's article as I had to make some tweaks to its parser and post-processor due to the wide assortment of graphics driver/hardware combinations, joining the ATI and AMD data, etc compared to the statistics collection on more basic/uniform hardware components. The sample set used was a maximum of 100,000 systems per year with the data being collected through the Phoronix Test Suite and OpenBenchmarking.org.

  • Phoronix Test Suite 7.8 M2 Released As "Folldal" Development Heats Up

    Just one week after Phoronix Test Suite 7.8 Milestone 1, the second development release of 7.8-Folldal is now available for testing.

    Phoronix Test Suite 7.8 M2 is heavier on the end-user facing changes as this quarterly development cycle heats up and also initial planning underway for Phoronix Test Suite 8.0 that in turn will ship this summer.

Benchmarking Ubuntu's Low-Latency Kernel & Liquorix Post-Meltdown

Filed under
Graphics/Benchmarks
Security
Ubuntu

The Ubuntu low-latency kernel is designed for, well, low-latency workloads like audio processing/recording. The lowlatency kernel compared to the generic Linux x86_64 kernel enables IRQ_FORCED_THREADING_DEFAULT, disables TREE_RCU in favor of PREEMPT_RCU, disables OPTPROBES, enables UNINLINE_SPIN_UNLOCK while disables the INLINE_*_UNLOCK tunables, enables PREEMPT support, changes to 1000Hz tick from 250Hz, and enables LATENCYTOP support.

The Liquorix kernel continues to be a bit more unique and among its alterations compared to a generic kernel is Zen interactive tuning, making use of the MuQSS process scheduler, hard kernel preemption, BFQ I/O scheduler by default, network optimizations, and more as outlined at Liquorix.net. Liquorix also defaults to CPUFreq on Intel CPUs and uses the ondemand governor rather than the other tested kernels defaulting to P_State powersave.

For these tests were benchmarks of 4.13.0-25-generic (the current default Ubuntu 17.10 kernel with KPTI patched), 4.14.13-041413-generic as the latest upstream stable kernel from the Ubuntu Mainline Kernel PPA, 4.14.13-041413-lowlatency as the equivalent low-latency Ubuntu kernel, and then 4.14.0-13.1-liquorix as the latest Liquorix kernel via its Launchpad PPA. All of these kernels had KPTI protection present and enabled, none of them currently have the (currently out-of-tree) Retpoline support.

    Honestly speaking, I have started using media player software less often. That’s probably because of the online streaming boom in the last couple of years.

  • Librsvg gets Continuous Integration

    One nice thing about gitlab.gnome.org is that we can now have Continuous Integration (CI) enabled for projects there. After every commit, the CI machinery can build the project, run the tests, and tell you if something goes wrong.

    Carlos Soriano posted a "tips of the week" mail to desktop-devel-list, and a link to how Nautilus implements CI in Gitlab. It turns out that it's reasonably easy to set up: you just create a .gitlab-ci.yml file in the toplevel of your project, and that has the configuration for what to run on every commit.

  • The Brutal Lifecycle of JavaScript Frameworks

    Using the Stack Overflow Trends tool and some of our internal traffic data, we decided to take a look at some of the more prominent UI frameworks: Angular, React, Vue.js, Backbone, Knockout, and Ember.
     

  • Visualizing Molecules with Python

    The PyMOL Wiki also hosts a script library, and it's a good place to look before you start down the road of creating your own script, as someone else may have run into the same issue and may have found a solution you can use. If nothing else, you may be able to find a script that could serve as a starting point for your own particular problem.

    When you're are done working with PyMOL, there are many different ways to end the session. If there is work you are likely to pick up again and continue with, click File→Save Session to save all of the work you just did, including all of the transitions applied to the view. If the changes you made were actually structural, rather than just superficial changes to the way the molecule looked, you can save those structural changes by selecting File→Save Molecule. This allows you to write out the new molecule to a chemical file format, such as a PDB file.

    If you need output for publications or presentations, a few different options are available. Clicking File→Save Image As allows you to select from saving a regular image file in PNG format or writing out data in a POVRay or VRML 3D file format. If you are doing a fancier presentation, you even can export a movie of your molecule by clicking File→Save Movie As. This lets you generate an MPEG movie file that can be used either on a web-based journal or within a slide deck for a presentation.

  • KPTI Support For 64-bit ARM Getting Buttoned Up Ahead Of Linux 4.16

    Kernel Page Table Isolation (KPTI) landed at the start of the year for x86/x86_64 systems for fending off the much talked about CPU attacks while the AMD64 / 64-bit ARM code is still a work-in-progress but looks like it will be squared away for the upcoming Linux 4.16 kernel cycle.

    There is this Git branch and the base work for those wishing to track the last minute alterations. There is currently the latest KPTI page table isolation patches for ARM64 and does include a return trampoline, a new HARDEN_BRANCH_PREDICTOR Kconfig switch, branch predictor hardening for Falkor and Cortex-A CPUs, and other security hardening improvements.

  • 'Very high level of confidence' Russia used Kaspersky software for devastating NSA leaks

    Three months after U.S. officials asserted that Russian intelligence used popular antivirus company Kaspersky to steal U.S. classified information, there are indications that the alleged espionage is related to a public campaign of highly damaging NSA leaks by a mysterious group called the Shadow Brokers.

    “That’s a Russian intelligence operation,” a former senior intelligence official, who requested anonymity to speak bluntly, told Yahoo Finance. “They’ve gotten a lot noisier than they used to be.”

The $18 Raspberry Pi Zero WH adds a soldered 40-pin GPIO header to the Zero W for easier prototyping or taking advantage of the new GPIO Expander tool, which lets you access your Pi’s GPIO pins from a PC running Debian Stretch.

Raspberry Pi Trading has launched a variation on the Raspberry Pi Zero W that makes it more like a regular Raspberry Pi SBC and less like a computer-on-module. Designed for those who would prefer not to solder, the new Raspberry Pi Zero W adds a “professionally soldered” 40-pin GPIO header, enabling easier prototyping or a better fit for temporary projects that need the Zero W’s small size and wireless radios, but don’t require the permanence of soldered connections.

From an underdog to a kennel master. That's probably the best, most succinct way to describe MX Linux. While you still may be confused about its heritage, with words like Mepis and AntiX slipping in, it's one of the more refined Xfce distros around, and I have been thoroughly impressed by the last version, MX-16. As it turns out, I proudly crowned it the Best of Xfce 2017 distro. It also notched very high on the overall annual best-of competition.

Now, there's a new version out. I will first conduct the test on the old LG laptop, but now that I've managed to fix the read-only UEFI on my Lenovo G50 machine, I will conduct a second test on that laptop - provided everything works fine in this first review. So we have ancient hardware, Nvidia graphics, dual boot. Commence.

Debian Developers: Google Summer of Code, Quick Recap of 2017

  • RHL'18 in Saint-Cergue, Switzerland
    In between eating fondue and skiing, I found time to resurrect some of my previous project ideas for Google Summer of Code. Most of them are not specific to Debian, several of them need co-mentors, please contact me if you are interested.
  • Quick recap of 2017
         After the Stretch release, it was time to attend DebConf’17 in Montreal, Canada. I’ve presented the latest news on the Debian Installer front there as well. This included a quick demo of my little framework which lets me run automatic installation tests. Many attendees mentioned openQA as the current state of the art technology for OS installation testing, and Philip Hands started looking into it. Right now, my little thing is still useful as it is, helping me reproduce regressions quickly, and testing bug fixes… so I haven’t been trying to port that to another tool yet. I also gave another presentation in two different contexts: once at a local FLOSS meeting in Nantes, France and once during the mini-DebConf in Toulouse, France. Nothing related to Debian Installer this time, as the topic was how I helped a company upgrade thousands of machines from Debian 6 to Debian 8 (and to Debian 9 since then). It was nice to have Evolix people around, since we shared our respective experience around automation tools like Ansible and Puppet.
