Hot on the heels of a successful Kickstarter campaign, the OpenShot video editor project has announced its schedule (still targeting December 2013, more detailed plan coming soon) and a switch to Qt 5. "One of the biggest decisions we have made so far is to switch the user interface toolkit that OpenShot uses from GTK+ to Qt. We have carefully considered our options, and our team believes it is the only reasonable path forward. A few big contributing factors to choosing Qt was the performance of embedding HTML and JavaScript (for our timeline and curve editing widgets), native-looking widget rendering (on Mac, Windows, and Linux), improved tools for designing interfaces, and the easy ability to use OpenGL to display our video preview widget."

In a lengthy blog post, Emmanuel Deloget interviews nine developers of GPU drivers and tools for ARM system-on-chip (SoC) devices. Questions range from the status of various projects and how the projects got started to intra-project collaboration and the future of the ARM platform. The developers and projects are: Connor Abbot - Open GPU Tools, Eric Faye-Lund - grate (for Tegra GPUs), Herman H. Hermitage - Videocore (for Broadcom GPUs), Luc Verhaegen - lima (for MALI GPUs), Matthias Gottschlag - Videocore (for Broadcom GPUs), Rob Clark - freedreno (for Adreno GPUs), Thierry Reding - grate (for Tegra GPUs), Scott Mansell - Videocore (for Broadcom GPUs), and Wladimir J. van der Laan - etna_viv (for Vivante GPUs).

On his blog, Mark Shuttleworth dashes the hopes of those looking for a Mary Poppins-inspired release name for Ubuntu 13.10. "Slipping the phrase 'ring ring' into the codename of 13.04 was, frankly, a triumph of linguistic engineering. And I thought I might quit on a high ... For a while, there was the distinct possibility that Rick's Rolling Release Rodeo would absolve me of the twice-annual rite of composition that goes into the naming of a new release. That, together with the extent of my travels these past few months, have left me a little short in the research department." No spoilers here, other than: the name is two words, an adjective and an animal, both of which start with "S".

Sebastian Kügler covers a meeting of the Plasma team. "The developers laid out the plans for an eventual release of Plasma Workspaces 2, based on KDE Frameworks 5 and Qt5. Wayland is also part of this plan. Starting with Plasma Worskpaces 2, Wayland will join X11 as a supported windowing environment, and all new development is taking this into consideration. Wayland is a replacement for most of the functionality which is today offered by Xorg. Wayland simplifies the graphics stack significantly with the goal of making every frame shown on screen perfect, something that is hard to achieve reliably with X11. Wayland's leaner graphics stack and improved security model also make it more appropriate for use on modern devices. As such, it is widely seen as the successor to X11 in the Free software ecosystem. Most of the gruntwork needed for this transition is already offered in Qt, however, there are still quite some X11-dependent code pathes in the KDE Frameworks, especially in KWin and the Oxygen widget style. While KWin is making excellent progress towards being able to be used as Wayland compositor, the future of the Oxygen widget style is still an unsolved problem."
