  • Ubuntu 14.04 LTS Gets Compiler-Based Retpoline Kernel Mitigation for Spectre V2

    Canonical announced today the availability of a new kernel security update for Ubuntu 14.04 LTS (Trusty Tahr) operating systems running the Linux 3.13 kernel to fix the second variant of the Spectre vulnerability on both 32-bit and 64-bit installations.

    On January 23, 2018, Canonical updated the kernel packages of Ubuntu 14.04 LTS (Trusty Tahr) to version linux-image 3.13.0-141.190, patching the Spectre Variant 2 security vulnerability discovered by Jann Horn, for the 64-bit (amd64) hardware architecture.

    The Spectre flaw can be exploited by a local attacker to expose sensitive information from kernel memory on modern microprocessors with branch prediction and speculative execution capabilities. Canonical now added support for 32-bit hardware architectures as well for Ubuntu 14.04 LTS systems.

  • Give Your Linux Desktop a Fresh Look with the Canta Theme

    If your current Ubuntu desktop is looking a little dark and a little dated why not give it a refresh?

    And the perfect choice to help you do that is the Canta theme by serial theme maker Vince Liuice (of Vimix theme fame).

  • Kotlin Programming Language Now Available On Linux Distros As A Snap

    Over the past year, the adoption of Kotlin programming language has increased at a rapid pace. Apart from its long list of great features, Google’s announcement of making Kotlin an officially supported language for Android development was a major reason behind the same. Being a general-purpose language, Kotlin can also be used on various applications as well.

  • A Short Preview to elementary OS Juno

    elementary OS 5.0 codenamed "Juno" has not been released. But the development is already active, and fortunately we are able to try the components on elementary OS 0.4 Loki right now. I have installed some latest programs of Juno from elementary-daily PPA and show you how they look like here. In other words, this article is a short preview of the new elementary Installer of Juno, as well as AppCenter and some more Juno's new stuffs. Not only that, I mention here how to get them on Loki so you can also try them, as the original announcement doesn't explain that. Read on and have a try!

LAS 2018

  • LAS 2018
    This month I was at my second Libre Application Summit in Denver. A smaller event than GUADEC but personally was my favorite conference so far. One of the main goals of LAS has been to be a place for multiple platforms to discuss the desktop space and not just be a GNOME event. This year two KDE members, @aleixpol and Albert Astals Cid, who spoke about release cycle of KDE Applications, Plasma, and the history of Qt. It is always interesting to see how another project solves the same problems and where there is overlap. The elementary folks were there since this is @cassidyjames home turf who had a great “It’s Not Always Techincal” talk as well as a talk with @danrabbit about AppCenter which are both very important areas the GNOME Project needs to improve in. I also enjoyed meeting a few other community members such as @Philip-Scott and talk about their use of elementary’s platform.
  • Developer Center Initiative – Meeting Summary 21st September
    Since last blog post there’s been two Developer Center meetings held in coordination with LAS GNOME Sunday the 9th September and again Friday the 21st September. Unfortunately I couldn’t attend the LAS GNOME meeting, but I’ll cover the general progress made here.

The "Chinese EPYC" Hygon Dhyana CPU Support Still Getting Squared Away For Linux

Back in June is when the Linux kernel patches appeared for the Hygon Dhyana, the new x86 processors based on AMD Zen/EPYC technology licensed by Chengdu Haiguang IC Design Co for use in Chinese data-centers. While the patches have been out for months, they haven't reached the mainline kernel quite yet but that might change next cycle. The Hygon Dyhana Linux kernel patches have gone through several revisions and the code is mostly adapting existing AMD Linux kernel code paths for Zen/EPYC to do the same on these new processors. While these initial Hygon CPUs appear to basically be re-branded EPYC CPUs, the identifiers are different as rather than AMD Family 17h, it's now Family 18h and the CPU Vendor ID is "HygonGenuine" and carries a new PCI Express device vendor ID, etc. So the different areas of the kernel from CPUFreq to KVM/Xen virtualization to Spectre V2 mitigations had to be updated for the correct behavior.

Good Support For Wayland Remote Desktop Handling On Track For KDE Plasma 5.15

The KDE Plasma 5.15 release due out next year will likely be in good shape for Wayland remote desktop handling. The KDE Plasma/KWin developers have been pursuing Wayland remote desktop support along a similar route to the GNOME Shell camp by making use of PipeWire and the XDG-Desktop-Portal. Bits are already in place for KDE Plasma 5.13 and the upcoming 5.14 release, but for the 5.15 release is now where it sounds like the support may be in good shape for end-users. Read more

Linux developers threaten to pull “kill switch”

Linux powers the internet, the Android in your pocket, and perhaps even some of your household appliances. A controversy over politics is now seeing some of its developers threatening to withdraw the license to all of their code, potentially destroying or making the whole Linux kernel unusable for a very long time.
