Software: OCS Store and Movit 1.6

OCS Store: One Stop Shop All of Your Linux Software Customization Needs
One of the biggest selling points of desktop Linux, for me, is the centralized software distribution system. Ubuntu has Apt, Arch Linux has Pacman and Fedora’s got RPM. This centralized distribution means an increased stability, a superior integration between the apps and the operating system, and an enhanced security factor.

Movit 1.6 Released For GPU-Based Video Filter Library
Movit, the "Modern Video Toolkit", that aims to provide high-quality, high-performance GPU-based video filters is out with a new release.
The Movit 1.6 release today by Steinar Gunderson adds support for video effects that work as compute shaders. Gunderson's hopes for using more compute shaders in Movit didn't work out quite as planned with fragment shaders geberally being faster for this use-case. But this release does have compute shaders for deinterlacing as one area where it's faster.

Movit 1.6.0 released
I just released version 1.6.0 of Movit, my GPU-based video filter library.
The full changelog is below, but what's more interesting is maybe what isn't in it, namely the compute shader version of the high-quality resampling filter I blogged about earlier. It turned out that my benchmark setup was wrong in a sort-of subtle way, and unfortunately biased towards the compute shader. Fixing that negated the speed difference—it was actually usually a few percent slower than the fragment shader version, despite a fair amount of earlier tweaks. (It did use less CPU when setting up new parameters, which was nice for things like continuous zooms, but probably not enough to justify the GPU slowdown.)
Which means that after a month or so of testing and performance tuning, I had to scrap it—it's sad to notice so late (I only realized that something was wrong as I started writing up the final documentation, and figured I couldn't actually justify why I would let one of them chain with other effects and the other one not), but it's a sunk cost, and keeping it in based on known-bad benchmarks would have helped nobody. I've left it in a git branch in case the world should change.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
