KDE: Videos, Plasma and Itinerary

Filed under
KDE
  • So you want to make a KDE video...

    KDE is running a competition in search of the next great promotional video for KDE's Plasma desktop and KDE's applications.

    The prizes are two fantastic TUXEDO computers, one per category, which will undoubtedly boost your film rendering capacity. There are also 12 goodie packages for runner-ups, and who doesn't need more Linux shirts, caps and stickers?

    Although we have already received some interesting entries, we feel it may be time to help video artists out there with ideas from the judges themselves.

    Below, Julian Schraner, Ivana Isadora Devčić, and Paul Brown from the Promo team and Farid Abdelnour from the Kdenlive team give their views on what a KDE promotional video should look like, where to find resources, and which pitfalls may hurt your film if you fall for them.

  • Learning about our users

    In a product like Plasma, knowing the kind of things our existing users care about and use sheds light on what needs polishing or improving. At the moment, the input we have is either the one from the loudest most involved people or outright bug reports, which lead to a confirmation bias.

    What do our users like about Plasma? On which hardware do people use Plasma? Are we testing Plasma on the same kind of hardware Plasma is being used for?

    Some time ago, Volker Krause started up the KUserFeedback framework with two main features. First, allowing to send information about application’s usage depending on certain users’ preferences and include mechanisms to ask users for feedback explicitly. This has been deployed into several products already, like GammaRay and Qt Creator, but we never adopted it in KDE software.

    The first step has been to allow our users to tune how much information Plasma products should be telling KDE about the systems they run on.

  • [KDE] Itinerary extraction in Nextcloud Hub

    Nextcloud announced their latest release and among the many new features is itinerary extraction from emails. That’s using KDE’s extraction engine, the same that powers similar features in KMail as well.

Intel: HEVC, ANV Vulkan Driver, Linux 5.7 and New Security Hole

  • Intel Adds VA-API Acceleration For HEVC REXT To FFmpeg

    Intel open-source developers have contributed support for VA-API acceleration of HEVC REXT "Range Extensions" content with the widely-used FFmpeg library. HEVC Range Extensions are extensions to H.265 geared for areas of content distribution, medical imaging, still imaging, and more. Among the changes with HEVC REXT are supporting 4:2:2 and 4:4:4 chroma sampling formats. HEVC Range Extensions are laid out in much more detail in this IEEE.org paper.

  • Intel Boosts Gen7 GPU Vulkan Compute Performance By ~330% For Geekbench

    Intel's open-source "ANV" Vulkan driver for Linux doesn't see much attention for pre-Broadwell hardware but today it saw a big improvement for Vulkan compute on aging Gen7 Ivybridge/Haswell era hardware. Jason Ekstrand, the lead developer of the Intel ANV Vulkan driver, discovered that in their driver's pipeline code the data cache functionality would end up being disabled when a shader was pulled out of the pipeline cache. For Broadwell/Gen8+ the data cache bit was being ignored but this oversight ended up having huge implications for Gen7 Intel graphics hardware (Ivybridge/Haswell) as the oldest supported by Intel's Vulkan driver.

  • Intel Has Accumulated 400+ Graphics Driver Patches So Far For Linux 5.7

    Intel just sent out their initial pull request of new feature changes/improvements to DRM-Next that in turn is for landing in about one month's time when the Linux 5.7 merge window kicks off. With taking longer than usual to send in their first round of feature updates, this first of several pull requests already amounts to over 400 patches. While it is a big pull request given the extra time for patches to accumulate, there aren't too many user-facing changes. Though there is a lot of enablement work for Tiger Lake as well as continuing Gen11 Ice Lake and Elkhart Lake work. For Ice Lake / Elkhart Lake there are a number of driver workarounds added. For Gen12 / Tiger Lake there are workarounds, display fixes, RPS is re-enabled, and other work.

  • Intel KVM Virtualization Hit By Vulnerability Over Unfinished Code

    At least not another hardware vulnerability, but CVE-2020-2732 appears to stem from unfinished code within the Intel VMX code for the Linux kernel's Kernel-based Virtual Machine (KVM) support. CVE-2020-2732 as of writing isn't yet public but we've been closely monitoring it since seeing a peculiar patch series earlier today and not finding much information on it.

    On this episode of This Week in Linux, we got some new releases from core projects like Mesa & PipeWire and we also got some App News from MyPaint, GTK and a new convergent apps project called Maui. Then we’ll check out some distro news regarding the Untangle Firewall and some Red Hat news about CoreOS Container Linux. Later in the show, we’ll cover some really interesting news from Nvidia about Ray Tracing to Vulkan. Someone in the UK Police thought it was a good idea to warn parents their kids may become hackers and Microsoft announced their Microsoft Defender is coming to Linux. Then we’ll round out the show with some great deals for Games, Books and Comics from Humble Bundle. All that and much more on Your Weekly Source for Linux GNews!

  • Data School: How to merge DataFrames in pandas (video)

    In my new pandas video, you're going to learn how to use the "merge" function so that you can combine multiple datasets into a single DataFrame. Merging (also known as "joining") can be tricky to do correctly, which is why I'll walk you through the process in great detail. By the end of the video, you'll be fully prepared to merge your own DataFrames!

Events: LibOCon, CHAOSScon, SUSE in Paris, Open Networking & Edge Summit North America 2020

  • LibreOffice Conference 2021 Call for Locations

    Once a year, the LibreOffice Community gathers for a global community event: the LibreOffice Conference, or LibOCon. After a series of successful events – Paris, October 2011; Berlin, October 2012; Milan, September 2013; Bern, September 2014; Aarhus, September 2015; Brno, September 2016; Rome, October 2017; Tirana, September 2018 and Almeria, September 2019 – the venue for 2020 is Nuremberg, Germany. To ease the organization, TDF Board of Directors has decided to open the call for location for 2021 earlier this year, to give the 2021 event organizers the opportunity of attending the conference in Nurembers in October 2020. The LibreOffice Conference takes place between September and November, with a preference for September. The deadline for sending in proposals is June 30, 2019. After receiving the applications, we will evaluate if all pre-conditions have been met and the overall content of the proposal, and give all applicants a chance to answer questions and clarify details if needed.
