Beginning yesterday and continuing today are several patch series beginning to lay the foundation in the AMDGPU kernel graphics driver for enabling some next-generation graphics IP. Due to the AMD graphics driver block by block enablement strategy and IP-based discovery adopted by their driver over the past few years, it's not clear what this new hardware enablement is for whether it's RDNA5 / UDNA or some RDNA4 refresh. In any event, the Linux driver enablement has begun.

Yesterday saw the PSP 15.0.8 IP posted. Not much is revealed by this updated Platform Security Processor (PSP) block and an incremental revision over what's already supported by the AMDGPU driver. The Platform Security Processor block on AMD GPU hardware handles firmware validation and other low-level security-related tasks.

Linux hardware vendor Slimbook announced today the launch of the KDE Slimbook VII laptop to celebrate 8 years of collaboration with the KDE project in creating the best Plasma-powered Linux notebooks.

Designed for KDE Plasma users and optimized for the Linux ecosystem, the KDE Slimbook VII laptop features a premium aluminum chassis in a sophisticated slate-blue color, an AMD Ryzen AI 9 365 processor with integrated AMD Radeon 880M graphics, up to 128 GB DDR5 RAM, and up to 8 TB NVMe PCIe 4.0 SSD storage.

The KDE Slimbook VII Linux laptop also features a 16-inch WQXGA display with 2560×1600 resolution, 100% sRGB, 16:10 aspect ratio, 400 nits brightness, and 165 Hz refresh rate, a multi-language backlit keyboard, and a cooling system with dual fans and dedicated keys to switch between power modes.

Xen 4.21 is out today as the newest feature release for this open-source hypervisor backed by AMD, Arm, AWS, and other organizations. Plus with Xen's use within automotive environments, Ford and Honda too.

Xen 4.21 ships with formally supporting the qemu-xen device models inside a Linux stub domain, which is a win for the likes of QubesOS.

For those using Xen on AMD hardware, there is now AMD CPU driver support for ACPI Collaborative Processor Performance Control (CPPC) for better power efficiency on Zen 3 and newer EPYC/Ryzen systems.

Xen also now supports Resizable BARs (ReBAR) for PVH Dom0 for exposing larger memory regions and better I/O efficiency. Xen logo

Xen 4.21 also brings a new PDX compression algorithm for lowering the hypervisor memory footprint. Xen 4.21 also brings various improvements to the Arm and RISC-V CPU support.

More details on today's Xen 4.21 release via the Linux Foundation press release and XenProject.org.

In mid-October, the Xubuntu download site was compromised and had directed users to a malicious zip file instead of the Torrent file that users expected. Elizabeth K. Joseph has published a postmortem of the incident, along with plans to avoid such a breach in the future:

To be perfectly clear: this only impacted our website, and the torrent links provided there.

If you downloaded or opened a file named "Xubuntu-Safe-Download.zip" from the Xubuntu downloads page during this period, you should assume it was malicious. We strongly recommend scanning your computer with a trusted antivirus or anti-malware solution and deleting the file immediately.

Nothing on cdimages.ubuntu.com or any of the other official Ubuntu repositories was impacted, and our mirrors remained safe as long as they were also mirroring from official resources.

None of the build systems, packages, or other components of Xubuntu itself were impacted.

Recordings from the GStreamer Conference 2025, held in London in late October, are now available on the GStreamer Conferences Archive site. Includes the GStreamer State of the Union talk by Tim-Philipp Müller, State of MPEG 2 Transport Stream (MPEG-TS) by Edward Hervey, and many others.

After years of pushback from the Federal Trade Commission over Meta’s acquisitions of Instagram and WhatsApp, Meta has defeated the FTC’s monopoly claims.

In a Tuesday ruling, US District Judge James Boasberg said the FTC failed to show that Meta has a monopoly in a market dubbed “personal social networking.” In that narrowly defined market, the FTC unsuccessfully argued, Meta supposedly faces only two rivals, Snapchat and MeWe, which struggle to compete due to its alleged monopoly.

But the days of grouping apps into “separate markets of social networking and social media” are over, Boasberg wrote. He cited the Greek philosopher Heraclitus, who “posited that no man can ever step into the same river twice,” while telling the FTC they missed their chance to block Meta’s purchase.

Essentially, Boasberg agreed with Meta that social media—as it was known in Facebook’s early days—is dead. And that means that Meta now competes with a broader set of rival apps, which includes two hugely popular platforms: TikTok and YouTube.

Nearly every Republican in the US House of Representatives voted on a bill to compel the release of documents tied to convicted sex offender Jeffrey Epstein.

The lone "nay" came from the Republican lawmaker from Louisiana, Clay Higgins, who defied his party saying his vote was a principled "NO".

"What was wrong with the bill three months ago is still wrong today," Higgins wrote on X. "It abandons 250 years of criminal justice procedure in America."

The resounding vote in favour of the Epstein bill, 427-1, marks a rare moment of bipartisanship on Capitol Hill. Hours later, the US senate too approved the legislation, clearing the way for the final act - President Donald Trump's signature.

Linux and Git inventor Linus Torvalds discussed AI in software development in an interview earlier this month, describing himself as "fairly positive" about vibe coding, but as a way into computing, not for production coding where it would likely be horrible to maintain.

Torvalds was interviewed by Dirk Hohndel, head of open source at Verizon, at the Linux Foundation Open Source Summit in Seoul, South Korea, earlier this month.

Torvalds is technical lead and maintainer of the Linux kernel, but said that "for the last almost 20 years, I've not been a programmer." As for Git, which he invented, "I really just look at it from the side."

Over on YouTube [DENKI OTAKU] runs us through how a 4-pin MOSFET works and what the extra Kelvin source pin does.

A typical MOSFET might come in a 3-pin TO-247 package, but there are 4-pin variants which include an extra pin for the Kelvin source, also known as source sense. These 4-pin packages are known as TO-247-4. The fourth pin provides an additional source for gate current return which can in turn lessen the effect of parasitic inductance on the gate-source when switching current, particularly at high speed.

Facing a shortage of organs needed by tens of thousands of patients, scientists have been studying pig organs as a potential solution. Genetically modified to suit humans and transplanted in the same way as human organs, the hope has been that they would function as well as those transplanted from human donors. But human bodies keep rejecting them.

A new study published November 13 in Nature provides new hope. In it, an international team of physicians detail how they prevented a human’s body from rejecting a pig organ—not once, but twice—for the first time ever.

Unboxing and testing even more weird old mouse devices on a Windows 98 PC! Checking out a Y2K "frutiger aero" Aqua Mouse, an Oberhofer solid cherry hand carved wooden wireless mouse, and a uh... Chrysler PT Cruiser from 2001 with tires on it. Yep.
