While the GNU Compiler Collection has supported OpenACC for a few years now as this parallel programming standard popular with GPUs/accelerators, the current implementation has been found to be inadequate for many real-world HPC workloads leveraging OpenACC. Fortunately, Siemens has been working to improve GCC's OpenACC kernels support.

GCC's existing OpenACC kernels construct has been found to be "unable to cope with many language constructs found in real HPC codes which generally leads to very bad performance." Fortunately, improvements are on the way and could potentially be mainlined in time for next year's GCC 12 stable release.

Fascinated by the look and feel of vintage electronics, [Democracity] decided to turn an old Sony Micro TV into a digital picture frame that would cycle through old family photos in style. You?d think the modern IPS widescreen display would stick out like a sore thumb, but thanks to the clever application of a 1/16? black acrylic bezel and the original glass still installed in the front panel, the new hardware blends in exceptionally well.

Driving the new display is a Raspberry Pi 4, which might sound overkill, but considering the front-end is being provided by DAKboard through Chromium, we can understand the desire for some extra horsepower and RAM. If it were us we?d probably have gone with a less powerful board and a few Python scripts, and of course there are a few turn-key open source solutions out there, though we?ll admit that this is probably faster and easier to setup.

• Announcing a New Video Series: Video Editing with Linux

  When we were designing the Librem 14, we wanted it to be our dream laptop in all possible respects. This meant squeezing the most resources we could fit in there that could run coreboot and PureBoot. We settled on a tenth generation Intel i7 10710U CPU with 6 cores and 12 threads and combined with up to 64GB RAM and fast NVMe storage, we feel this is a great laptop for resource-intensive tasks like video editing.

  Instead of just telling you about it, we thought it would be useful to show you. While we could just do a high-level marketing video that demonstrated a bit of video editing on the Librem 14, we thought it would be better (and more aligned with our Social Purpose) to invest in a complete tutorial series that would teach people how to edit videos on a Librem 14 running PureOS.

  We thought who better to teach you how to edit videos in Linux than someone who does it professionally, so we partnered with Gardiner Bryant to produce a complete series. This series will cover all the major aspects of video editing from selecting video editing software through to each step in the process.

• Why Universal Linux Apps are GREAT! - Invidious

  Universal Linux Apps/Packages (Flatpaks, Snaps, AppImages) seem to get a lot of hate in the Linux community, but why?! In this video, I talk about why this type of technology is not only necessary, but a good thing.

• Bad Documentation Doesn't Make Software Advanced! - Invidious

  Documentation is incredibly important but somehow we've got to a point where some people think that having good documentation is a bad thing or that it somehow makes the software for advanced users, I completely disagree and think if it's for advanced users the documentation is even more important.

• LHS Episode #430: Bag of Hammers

  Welcome to the 430th episode of Linux in the Ham Shack. In this action-packed episode, the hosts discuss topics including the JARL Hamfest, AMSAT events going virtual, JOTA and JOTI, vulnerabilities in OpenSSL, updates to the Linux kernel, Pat, Winlink, HAMRS and much more. Thank you for listening and have a great week.
