KDE: Astronomy on KDE, MQTT/GSoC, Konversation Tip

Filed under
KDE
  • Astronomy on KDE

    I recently switched to KDE and Plasma as my main desktop environment, so I thought I'd start digging into some of the scientific software available on KDE. First up is KStars, the desktop astronomy program.

  • LabPlot's MQTT in the finish line

    Hello everyone. GSoC is coming to its end, so I think that I should give a report about what's been done since the last post, and also make a brief evaluation, summary of the project itself.

    As I've written in my last post, the main focus was on improving the quality of the code, cleaning, optimizing and properly documenting it. And also making it more comestible for other developers.

    The next step was searching for bugs and then fixing them. In order to do this properly, I implemented a unit test for the main MQTT related features. This proved to be useful since it helped discover several hidden bugs and errors which were all corrected. The main features, that tests were developed for, are: checking if a topic contains another one, checking if two topics are "common topics" (meaning they only differ at only one level, and are the same size), managing messages, subscribing&unsubscribing.

  • PSA: Use SASL in konversation

    You probably have seen that Freenode has been getting lots of spam lately.

    To protect against that some channels have activated a flag that only allows authenticated users to enter the channel.

    If you're using the regular "nickserv" authentication way as I was doing, the authentication happens in parallel to entering the channels and you'll probably be rejected from joining some.

Kernel: Linux 4.19 and Vega 20 PowerPlay

  • Power Management Updates Land In The Linux 4.19 Kernel
    Intel's Rafael Wysocki has submitted the ACPI and power management updates today for the Linux 4.19 kernel which were subsequently merged by Linus Torvalds.
  • Linux 4.19 Git Contains a lot of Performance Impacting Spectre Mitigation Updates
    Another round of commits regarding anti-Spectre security have landed up in the Linux 4.19 kernel git tree, which may have possible performance impacts for the kernel. While Spectre is still only a somewhat theoretical threat, as its entirely too slow to be used in a serious attack, many folks are taking its future potential quite seriously and arming up against it.
  • Linux 4.19 Kernel to Receive a Ton of Audio Hardware Updates for Improved Linux Sound Capabilities
    Linux audiophiles may have something to rejoice about, as a recent pull request from SUSE’s Takashi Iwai focuses on a plethora of sound subsystem updates for the Linux 4.19 kernel, including a lot of latest hardware support and overall improvements for Linux’s audio capabilities.
  • Updated Vega 20 Open-Source Driver Patches Posted, Including PSP & PowerPlay Support
    Back in May AMD posted initial open-source "Vega 20" patches and support for that yet-to-launch graphics processor was subsequently merged for the Linux 4.18 kernel. More of the Vega 20 AMDGPU kernel driver enablement has now been posted. This latest 69,910 lines of code -- before fretting, most of that is auto-generated header files for the GPU -- notably adds PSP (Platform Security Processor) and SMU (System Management Unit) for Vega 20. With the SMU enablement code, it's also now wired in to enable Vega 20 PowerPlay support as well as related power/clocking-functionality like OverDrive overclocking is also available.
