TuxMachines: Ubuntu: Mir 0.31 Released, Server and LXD Status Reports

Wednesday 21st of March 2018 02:30:54 AM
  • Mir 0.31 Officially Released

    Mir 0.31 is now available as the latest version of the Canonical-developed display stack that continues implementing support for Wayland's protocols.

    Mir 0.31 has been in development for Ubuntu 18.04 LTS with several new features and today the release surfaced as v0.31.0.1, as an apparent brown paper bag release hours after v0.31.0 was tagged.

  • Server development summary – 20 March 2018

    If you have a server that you are using for Bionic testing, please look in /etc/netplan and give netplan a run through. Note that only new installs of Artful+ will be enabled for netplan.

  • LXD weekly status #39

    The focus for this week was on CEPH and LXD clustering, trying to get the last few remaining pieces to work together properly. We’ve tagged a couple more betas as we went through that.

TuxMachines: A new era for Linux's low-level graphics - Part 1

Wednesday 21st of March 2018 02:26:44 AM

Over the past couple of years, Linux's low-level graphics infrastructure has undergone a quiet revolution. Since experimental core support for the atomic modesetting framework landed a couple of years ago, the DRM subsystem in the kernel has seen roughly 300,000 lines of code changed and 300,000 new lines added, when the new AMD driver (~2.5m lines) is excluded. Lately Weston has undergone the same revolution, albeit on a much smaller scale.

Daniel Vetter's excellent two-part series on LWN covers the details quite well, but in short atomic has two headline features. The first is better display control: by grouping all configuration changes together, it is possible to change display modes more quickly and more reliably, especially if you have multiple monitors. The second is that it allows userspace to finally use overlay planes in the display controller for composition, bypassing the GPU.

A third, less heralded, feature is that the atomic core standardises user-visible behaviour. Before atomic, drivers had very wide latitude to implement whatever user-facing behaviour they liked. As a result, each chipset had its own kernel driver and its own X11 driver as well. With the rewrite of the core, backed up by a comprehensive test suite, we no longer need hardware-specific drivers to take full advantage of hardware features. With the substantial rework of Weston's DRM backend, we can now take full advantage of these. Using atomic gives us a smoother user experience, with better performance and using less power, whilst still being completely hardware-agnostic.

TuxMachines: Raspberry Pi CM3 carrier has an Artik MCU for offline Bluetooth

Tuesday 20th of March 2018 10:59:54 PM

Resin.io’s fleet-oriented “Fin” carrier runs its Docker-friendly ResinOS and Resin.io IoT framework on a Raspberry Pi Compute Module. It offers RPi 3 like ports, plus a mini-PCIe slot and an Artik 020 MCU for offline Bluetooth links.

Resin.io, the company behind the Linux/Javascript-based Resin.io IoT framework for deploying applications as Docker containers, as well as the related ResinOS 2.0 Linux distribution, has announced its first hardware product. Due to ship later this Spring for about $129, its Project Fin carrier board expands upon the Raspberry Pi Compute Module 3 Lite to support fleet operations.

    Harry (Lei) Zhang, together with the CTO of HyperHQ, Xu Wang, will present “CRI: The Second Boom of Container Runtimes” at KubeCon + CloudNativeCon EU 2018, May 2-4 in Copenhagen, Denmark. The presentation will clarify about more about CRI, container runtimes, KataContainers and where they are going. Please join them if you are interested in learning more.
  • Meet Gloo, the ‘Function Gateway’ That Unifies Legacy APIs, Microservices, and Serverless
    Gloo, a single binary file written in Go, can be deployed as a Kubernetes pod, in a Docker container, and now also on Cloud Foundry. The setup also requires a copy of Envoy, though the installation process can be greatly simplified through additional software developed by the company, TheTool. The user then writes configuration objects to capture the workflow logic.

  • The developer of Helium Rain gave an update on their sales, low overall sales but a high Linux percentage
    Helium Rain [Steam, Official Site], the gorgeous space sim from Deimos Games is really quite good so it's a shame they've seen such low overall sales. In total, they've had around 14,000€ (~$17,000) in sales which is not a lot for a game at all. The good news, is that out of the two thousand copies they say they've sold, a huge 14% of them have come from Linux. It's worth noting, that number has actually gone up since we last spoke to them, where they gave us a figure of 11% sales on Linux.

Glibc 2.27 also has memory protection keys support and other feature additions, but the performance potential has been most interesting to us.

  • IRS Website Crash Reminder of HealthCare.gov Debacle as OMB Pushes Open Source
    OMB is increasingly pushing agencies to adopt open source solutions, and in 2016 launched a pilot project requiring at least 20 percent of custom developed code to be released as open source – partly to strengthen and help maintain it by tapping a community of developers. OMB memo M-16-21 further asks agencies to make any code they develop available throughout the federal government in order to encourage its reuse. “Open source solutions give agencies access to a broad community of developers and the latest advancements in technology, which can help alleviate the issues of stagnated or out-dated systems while increasing flexibility as agency missions evolve over time,” says Henry Sowell, chief information security officer at Hortonworks Federal. “Enterprise open source also allows government agencies to reduce the risk of vendor lock-in and the vulnerabilities of un-supported software,” he adds.
  • Migrations: the sole scalable fix to tech debt.

    Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This isn't because they're bad processes or poor tools, quite the opposite: the fact that something stops working at significantly increased scale is a sign that it was designed appropriately to the previous constraints rather than being over designed.

    A mobile application built by a third party for the RSA security conference in San Francisco this week was found to have a few security issues of its own—including hard-coded security keys and passwords that allowed a researcher to extract the conference's attendee list.

  • The Security Risks of Logging in With Facebook
     

    In a yet-to-be peer-reviewed study published on Freedom To Tinker, a site hosted by Princeton's Center for Information Technology Policy, three researchers document how third-party tracking scripts have the capability to scoop up information from Facebook's login API without users knowing. The tracking scripts documented by Steven Englehardt, Gunes Acar, and Arvind Narayanan represent a small slice of the invisible tracking ecosystem that follows users around the web largely without their knowledge.
