  • 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!

KDE/Qt: Qt Contributor Summit 2018, Integrating Cloud Solutions with Qt, FreeBSD, and Konsole

  • Qt Contributor Summit 2018
    One bit especially interesting is the graphics stack. Back in Qt 5.0, Qt took the liberty of limiting the graphics stack to OpenGL, but the world has changed since: On Windows the only proper stack is Direct3D 12, Apple introduced Metal and recently deprecated OpenGL and Vulkan is coming rather strong. It looks like embracing these systems transparently will be one of the most exciting tasks to achieve. From a KDE & Plasma perspective I don’t think this is scary, OpenGL is here to stay on Linux. We will get a Framework based on a more flexible base and we can continue pushing Plasma, Wayland, Plasma Mobile with confidence that the world won’t be crumbling. And with a bit of luck, if we want some parts to use Vulkan, we’ll have it properly abstracted already.
  • Integrating Cloud Solutions with Qt
    These days, using the cloud for predictive maintenance, analytics or feature updates is a de facto standard in the automation space. Basically, any newly designed product has some server communication at its core. However, the majority of solutions in the field were designed and productized when communication technology was not at today’s level. Still, attempts are being made to attach connectivity to such solutions. The mission statement is to “cloudify” an existing solution, which uses some internal protocol or infrastructure.
  • KDE on FreeBSD – June 2018
    It’s been a while since I wrote about KDE on FreeBSD, what with Calamares and third-party software happening as well. We’re better at keeping the IRC topic up-to-date than a lot of other sources of information (e.g. the FreeBSD quarterly reports, or the f.k.o website, which I’ll just dash off and update after writing this).
  • Konsole’s search tool
    Following my konsole’s experiments from the past week I came here to show something that I’m working on with the VDG, This is the current Konsole’s Search Bar. [...] I started to fix all of those bugs and discovered that most of them happened because we had *one* search bar that was shared between every terminal view, and whenever a terminal was activated we would reposition, reparent, repaint, disconnect, reconnect the search bar. Easiest solution: Each Terminal has it’s own search bar. Setuped only once. The one bug I did not fix was the Opening / Closing one as the searchbar is inside of a layout and layouts would reposition things anyway. All of the above bugs got squashed by just moving it to TerminalDisplay, and the code got also much cleaner as there’s no need to manual intervention in many cases. On the review Kurt – the Konsole maintainer – asked me if I could try to make the Search prettier and as an overlay on top of the Terminal so it would not reposition things when being displayed.

LibreOffice 6.0 Is Now Ready for Mainstream Users and Enterprise Deployments

LibreOffice 6.0.5 is here one and a half months after the LibreOffice 6.0.4 point release to mark the open-source office suite as ready for mainstream users and enterprise deployments. The Document Foundation considers that LibreOffice 6.0 has been tested thoroughly and that it's now ready for use in production, enterprise environments. Until now, The Document Foundation only recommended the LibreOffice 6.0 office suite to bleeding-edge users while urging enterprises and mainstream users to use the well-tested LibreOffice LibreOffice 5.4 series, which reached end of life on June 11, 2018, with the last point release, LibreOffice 5.4.7.
