  • AV1 Is Making Progress As A Royalty-Free Video Codec Based Off VP9

    The Alliance for Open Media continues working hard on their first video codec, dubbed AV1, that started off with the VP9 libvpx code-base and are pursuing to do for free video codecs what the Opus codec has done for audio.

    AV1 strives to be a viable open, royalty-free video codec suitable for Internet video and developed by Alliance for Open Media. AV1 is still hoping to succeed VP9 and be a viable contender to HEVC/H.265, but not until later in 2017 is the bitstream format expected to be finalized and thus not until 2018 when we may begin seeing some AV1 adoption.

  • You Can Now Install Various KDE Apps from the Ubuntu 16.04 LTS Snappy Store

    In December last year, we reported on the work done by KDE Community developer Harald Sitter to bundle the official KDE applications as Snaps and make them available for installation on the Ubuntu Snappy Store.

    A Snap build of the latest KDE Frameworks 5, a collection of add-on libraries for Qt 5, made its way into the Snappy Store, and can be easily installed on the Ubuntu 16.04 LTS (Xenial Xerus) operating system if you execute the "sudo snap install kde-frameworks-5" command in a terminal emulator.

  • LibreOffice 5.3 Upgrade Brings Open-Source Office Suite to the Cloud

    The open-source LibreOffice office application suite has been improving steadily since 2010, when it was forked from the Oracle OpenOffice suite. The latest incremental milestone is LibreOffice version 5.3, released Feb. 1 and providing users with new features and improved performance. LibreOffice bundles multiple applications including the Writer Document, Calc Spreadsheet, Impress Presentation, Draw, Math Formula and Base Database. Among the numerous feature updates in Writer are new PDF document-handling capabilities that enable users to import and digitally sign existing documents. Writer also benefits from new table formatting capabilities and an easier-to-use side menu for page options. LibreOffice typically is available as the default office suite in many Linux distributions and freely available for Apple Mac OS X and Microsoft Windows applications. Plus, with LibreOffice 5.3, the whole office suite also can be deployed in the cloud. In this slide show, eWEEK takes a look at key features of LibreOffice 5.3.

  • A Makefile for your Go project

    My most loathed feature of Go is the mandatory use of GOPATH: I do not want to put my own code next to its dependencies. Hopefully, this issue is slowly starting to be accepted by the main authors. In the meantime, you can workaround this problem with more opinionated tools (like gb) or by crafting your own Makefile.

Digital audio and video editing in GNU/Linux

  • Linux Digital Audio Workstation Roundup
    In the world of home studio recording, the digital audio workstation is one of the most important tools of the trade. Digital audio workstations are used to record audio and MIDI data into patterns or tracks. This information is then typically mixed down into songs or albums. In the Linux ecosystem, there is no shortage of Digital audio workstations to chose from. Whether you wish to create minimalist techno or full orchestral pieces, chances are there is an application that has you covered. In this article, we will take a brief look into several of these applications and discuss their strengths and weaknesses. I will try to provide a fair evaluation of the DAWs presented here but at the end of the day, I urge you to try a few of these applications and to form an opinion of your own.
  • Shotcut Video Editor Available As A Snap Package [Quick Update]
    Shotcut is a free, open source Qt5 video editor developed on the MLT Multimedia Framework (it's developed by the same author as MLT), available for Linux, Windows and Mac.

KDE Leftovers

  • Fedora 25 KDE: disappointing experience
    Fedora is not a frequent guest on the review deck of Linux notes from DarkDuck blog. The most recent review was of Fedora 22 back in July 2015. That was a review of the GNOME version, the most native for Fedora. You are probably aware of the tight link between the GNOME project and RedHat, the Fedora Project main sponsor.

  • Plasma in a Snap?
    Shortly before FOSDEM, Aleix Pol asked if I had ever put Plasma in a Snap. While I was a bit perplexed by the notion itself, I also found this a rather interesting idea. So, the past couple of weeks I spent a bit of time here and there on trying to see if it is possible.
  • QStringView Diaries: Advances in QStringLiteral
    This is the first in a series of blog posts on QStringView, the std::u16string_view equivalent for Qt. You can read about QStringView in my original post to the Qt development mailing-list, follow its status by tracking the “qstringview” topic on Gerrit and learn about string views in general in Marshall Clow’s CppCon 2015 talk, aptly named “string_view”.
  • Making Movies with QML
    One of the interesting things about working with Qt is seeing all the unexpected ways our users use the APIs we create. Last year I got a bug report requesting an API to set a custom frame rate for QML animations when using QQuickRenderControl. The reason was that the user was using QQuickRenderControl as an engine to render video output from Qt Quick, and if your target was say 24 frames per second, the animations were not smooth because of how the default animation driver behaves. So inspired by this use case I decided to take a stab at creating such an example myself.

  • HITMAN Linux Benchmarks On 12 NVIDIA GPUs
    Last week Feral Interactive released the much anticipated port of HITMAN for Linux. While at first it didn't look like this Linux game port would work out for our benchmarking requirements, thanks to Feral it does indeed work for another interesting Linux gaming test perspective. For our initial HITMAN Linux benchmarks are tests from 12 NVIDIA GeForce GPUs while our Radeon tests will come tomorrow.
