Arduino Uno Q - LED Matrix - Rain

I covered the basics of the Arduino Uno Q, but I very much wanted to experiment with the LED Matrix. The LED Matrix is an 8 by 13 grid of LEDs that are blue. I won't get into how long it took me to get a single LED to light up, but it was definitely longer than it should have been. It took a while to get it streamlined and then make it something worth watching. We are going to make rain on the Arduino Uno Q. Basic Setup The first thing you need is a system hooked up to the Arduino... https://www.linux.org/threads/arduino-uno-q-led-matrix-rain.71072/

CHUWI UniBook With Intel Wildcat Lake For A $449 Linux-Friendly Laptop

CHUWI recently launched the UniBook laptop powered by the Intel Core 3 304 "Wildcat Lake" SOC and priced at just $449 USD. Especially with today's high component pricing, a brand new sub-$500 laptop is extremely rare. Rather than using some dated SoC, it uses Wildcat Lake as Intel's new value option alternative to the Core 3 Series Ultra "Panther Lake" SoCs. This was our first time testing out Intel Wildcat Lake and that SoC plus the overall CHUWI UniBook has been working out well on Linux for those looking at a laptop in the sub-$500 space.

New Patches Provide HDMI 1.4 3D Mode Support For AMD Radeon Graphics On Linux

It turns out one of the feature limitations of the AMDGPU Linux graphics driver is HDMI 1.4 3D output support with frame packing, top-and-bottom, and side-by-side options for transmitting simultaneous video streams. I wasn't aware of this limitation for the lack of any 3D displays and many Linux enthusiasts/gamers as well, but if you happen to have a compatible HDMI 1.4 3D display, there are pending patches to finally make this a reality...

DirectX Support Promoted To Official Target Within LLVM

Over the past four years there has been a lot of work on a DirectX back-end within the LLVM compiler stack. Microsoft has backed the initiative for being able to lower LLVM IR into the DirectX Intermediate Language (DXIL) for execution by Windows DirectX 12 graphics drivers. This back-end is now officially supported...

LLVM Merges Support For AMD's RMPCHKD, RMPREAD & RMPOPT Instructions

With the Linux kernel still working toward landing support for AMD's RMPOPT optimization for helping to reduce overhead on SEV-SNP enabled servers, the LLVM/Clang compiler has in turn prepped for the milestone by landing support for the RMPOPT, RMPREAD, and RMPCHKD instructions for Zen 5 and newer...

KDE’s new Photos app offers a sleek alternative to Gwenview

Photos is a new(ish) image viewer and organiser for KDE Plasma aiming to give Gwenview a run for its pixels. Linux distributions that use KDE Plasma typically ship Gwenview, which has been the KDE image app for over 25 years. It’s a solid, feature-filled and Qt-based tool that and many love and rely on to view, manage and edit images. But development on Gwenview has slowed – and it legacy could be to blame. As GNOME found in its efforts to modernise the Evince document viewer, updating old software can require rewriting and rewiring large chunks of an antiquated codebase. […]
