  • Why Linus is right (as usual)

    Last year, some security “hardening” code was added to the kernel to prevent a class of buffer-overflow/out-of-bounds issues. This code didn’t address any particular 0day vulnerability, but was designed to prevent a class of future potential exploits from being exploited. This is reasonable.

    This code had bugs, but that’s no sin. All code has bugs.
    The sin, from Linus’s point of view, is that when an overflow/out-of-bounds access was detected, the code would kill the user-mode process or kernel. Linus thinks it should have only generated warnings, and let the offending code continue to run.

  • Kube-Node: Let Your Kubernetes Cluster Auto-Manage Its Nodes

    As Michelle Noorali put it in her keynote address at KubeCon Europe in March of this year: the Kubernetes open source container orchestration engine is still hard for developers. In theory, developers are crazy about Kubernetes and container technologies, because they let them write their application once and then run it anywhere without having to worry about the underlying infrastructure. In reality, however, they still rely on operations in many aspects, which (understandably) dampens their enthusiasm about the disruptive potential of these technologies.

    One major downside for developers is that Kubernetes is not able to auto-manage and auto-scale its own machines. As a consequence, operations must get involved every time a worker node is deployed or deleted. Obviously, there are many node deployment solutions, including Terraform, Chef or Puppet, that make ops live much easier. However, all of them require domain-specific knowledge; a generic approach across various platforms that would not require ops intervention does not exist.

  • [LabPlot] Improved data fitting in 2.5

    Until now, the fit parameters could in principle take any values allowed by the fit model, which would lead to a reasonable description of the data. However, sometimes the realistic regions for the parameters are known in advance and it is desirable to set some mathematical constrains on them. LabPlot provides now the possibility to define lower and/or upper bounds for the fit parameters and to limit the internal fit algorithm to these regions only.

  • [GNOME] Maps Towards 3.28

    Some work has been done since the release of 3.26 in September. On the visual side we have adapted the routing sidebar to use a similar styling as is used in Files (Nautilus) and the GTK+ filechooser.

  • MiniDebconf in Toulouse

    I attended the MiniDebconf in Toulouse, which was hosted in the larger Capitole du Libre, a free software event with talks, presentation of associations, and a keysigning party. I didn't expect the event to be that big, and I was very impressed by its organization. Cheers to all the volunteers, it has been an amazing week-end!

  • DebConf Videoteam sprint report - day 0

    First day of the videoteam autumn sprint! Well, I say first day, but in reality it's more day 0. Even though most of us have arrived in Cambridge already, we are still missing a few people.

    Last year we decided to sprint in Paris because most of our video gear is stocked there. This year, we instead chose to sprint a few days before the Cambridge Mini-Debconf to help record the conference afterwards.

  • Libre Computer Board Launches Another Allwinner/Mali ARM SBC

    The Tritium is a new ARM single board computer from the Libre Computer Board project.

    Earlier this year the first Libre Computer Board launched as the Le Potato for trying to be a libre and free software minded ARM SBC. That board offered better specs than the Raspberry Pi 3 and aimed to be "open" though not fully due to the ARM Mali graphics not being open.

  • FOSDEM 2018 Will Be Hosting A Wayland / Mesa / Mir / X.Org Developer Room

    This year at the FOSDEM open-source/Linux event in Brussels there wasn't the usual "X.Org dev room" as it's long been referred to, but for 2018, Luc Verhaegen is stepping back up to the plate and organizing this mini graphics/X.Org developer event within FOSDEM.

  • The Social Network™ releases its data networking code

    Facebook has sent another shiver running up Cisco's spine, by releasing the code it uses for packet routing.

    Open/R, its now-open source routing platform, runs Facebook's backbone and data centre networks. The Social Network™ first promised to release the platform in May 2017.

    In the post that announced the release, Facebook said it began developing Open/R for its Terragraph wireless system, but since applied it to its global fibre network, adding: “we are even starting to roll it out into our data center fabrics, running inside FBOSS and on our Open Compute Project networking hardware like Wedge 100.”

  • Intel Icelake Support Added To LLVM Clang

    Initial support for Intel's Icelake microarchitecture that's a follow-on to Cannonlake has been added to the LLVM/Clang compiler stack.

  • Blockchain Moves Beyond its 'Moonshot' Phase
  • Some reading

    I've complained previously about disliking benchmarking. More generally, I'm not really a fan of performance analysis. I always feel like I get stuck at coming up with an approach to "it's going slower, why" beyond the basics. I watched a video of Brendan Gregg's talk from kernel recipes, and ended up going down the black hole1 of reading his well written blog. He does a fantastic job of explaining performance analysis concepts as well as the practical tools to do the analysis. He wrote a book several years ago and I happily ordered it. The book explains how to apply the USE method to performance problems across the system. This was helpful to me because it provides a way to generate a list of things to check and how to check them. It addresses the "stuck" feeling I get when dealing with performance problems. The book also provides a good high level overview of operating systems concepts. I'm always looking for references for people who are interested in kernels but don't know where to start and I think this book could fill a certain niche. Even if this book has been out for several years now, I was very excited to discover it.

  • Introducing container-diff, a tool for quickly comparing container images

    The Google Container Tools team originally built container-diff, a new project to help uncover differences between container images, to aid our own development with containers. We think it can be useful for anyone building containerized software, so we’re excited to release it as open source to the development community.

  • Compact DAQ systems offer a choice of 12- or 16-bit I/Os

    Advantech’s Linux-ready “MIC-1810” and “MIC-1816” DAQ computers offer 12- and 16-bit analog I/O, respectively, plus 24x DIOs, Intel CPUs, and 4x USB ports.

    Advantech’s MIC-1810 and MIC-1816 are digital acquisition computers that run Linux or Windows 7/8/10 on Intel 3rd Gen “Ivy Bridge” processors. If the aging CPU is a turn-off, keep in mind that many DAQ applications don’t require that much processing power, and perhaps Advantech’s “entry-level” label for the systems extends to the price, as well. The 165 x 130 x 59mm, DIN-rail mountable systems should also prove useful for environments with limited space.

  • The Quantum of Firefox: Why is this one unlike any other Firefox?

    The Mozilla Foundation has officially launched a radical rewrite of its browser, a major cross-platform effort to regain relevance in a world that seems to have forgotten Firefox. The much-rewritten browser claims to be 30 per cent faster with half the memory load, although this comes at the cost of compatibility, as Scott Gilbertson found here.

    The proof’s in the pudding, and this pudding doesn’t feel like the old Firefox behemoth at all. It’s long overdue.

    "Firefox is 13 years old – and very few applications have been around for 13 years without accruing technical debt,” Nick Nguyen, Mozilla’s VP of technology told us.

  • Linux 4.14 Release Provides Long Term Support and Larger Memory Limits

    Linus Torvalds officially released the Linux 4.14 kernel on Nov. 12, providing users of the open-source operating system with new features and long term support. Linux 4.14 is a special release in that it has been designated as an LTS (Long Term Support) meaning that it will be maintained for at least the next two years.

    Linux 4.14 is the fifth new major Linux kernel release in 2017, following the Linux 4.13 kernel that debuted on Sept. 3.

    "Go out and test the new 4.14 release, that is slated to be the next LTS kernel - and start sending me pull request for the 4.15 merge window," Torvalds wrote in his release announcement.

  • GNU/Linux Is Still Cooking

    t’s true that smartphones have taken a huge share of personal computing away from desktops and notebooks but there are still huge limitations around screen-size, computing power, storage etc. where smartphones are not enough. I’ve long recommended using smartphones and desktop equipment together. Every time I find my text runs outside a text-box or some page is viewable only in portrait mode in Android/Linux, I long for some way to get to GNU/Linux. Today, I get up off the sofa and walk to my desk. Perhaps some day, I’ll dock the smartphone and carry on. Now, I have to reopen work from the desktop PC I call Beast.

My manic-depressive mood-swings are on the manic side at the moment so next to baking sausage rolls (brabantse worstenbroodjes for which I will publish an updated recipe on this blog soon) and a batch of sourdough bread, I finally had the energy to fix the admin interface for the SlackDocs mailing lists, wrestled myself through 14,000+ emails in my administrative mailboxes, wrote a plan to migrate my LAN services from the ageing server to the new server I bought this summer (which involves conversion of several large databases to InnoDB and loads of custom packages), plus I binge-watched almost 2 full seasons of Stranger Things in 3 days’ time. I know I will crash hard in a couple of days but I hope to have a new Plasma ‘ktown’ update before that happens.

    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.

    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility. Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.

The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.
