Oracle Solaris 11.4.81 CBE is now available as the newest release of this Oracle Solaris "Common Build Environment" version that is essentially a community-supported. non-production version of Solaris intended for free / open-source software developers. Oracle Solaris 11.4.81 CBE comes after not seeing any CBE updates the past three years and now rather unexpectedly seeing this new version drop even with Solaris very rarely making any news these days...

It was just yesterday that Training Solo was made public as a new speculative execution CPU vulnerability affecting some Intel and Arm CPUs... Today another one is now public for Intel processors: Branch Privilege Injection...

With today's announcement of the AMD EPYC 4005P "Grado" entry-level server processors, up for review today are the EPYC 4565P and EPYC 4585PX processors as the top-end Zen 5 processors for budget server builds and basic bare metal server hosting. With the prior-generation EPYC 4004 series AMD was already leading over Intel's entry-level Xeon E processors that have become rather embarrassing for the company with its stagnate line-up of low-cost server processors. Now with the AMD EPYC 4005 series, AMD is in an even stronger position and providing a total knock-out to the new Xeon 6300P competition headlined by the Xeon 6369P flagship model.

Last year AMD launched the EPYC 4004 series for taking Ryzen based processor designs into the EPYC segment for entry-level servers with ECC memory support, server designs with BMCs, and various enterprise software certifications and industry qualifications. Today they are launching the EPYC 4005 series as their new Zen 5 based offerings for entry-level / budget server deployments and other instances when not needing as much compute power or connectivity and other high-end features found with the EPYC 9005 "Turin" processors.

Kdo ovládá váš počítač? Jste to skutečně vy nebo je to někdo jiný, kdo pro vás napsal uzavřený software, který může dělat cokoliv. Nejen o svobodě a nezávislosti mluvil na své přednášce Richard Stallman.

Prozatím jsme se zaměřili na assembler. Proč se však více nepoužívaly překladače vyšších programovacích jazyků? Dnes se na tuto otázku pokusíme částečně odpovědět otestováním několika dobových překladačů jazyka C.

The VUSec security researchers are at it again... The embargo is now lifted on another set of of security vulnerabilities affecting Intel processors as well as Arm core designs. This new vulnerability is dubbed Training Solo...

We finally have AMD's Strix Halo in the lab for benchmarking! HP has kindly sent over their ZBook Ultra 14-inch G1a mobile workstation: it's a beast being powered by the top-end AMD Ryzen AI Max+ PRO 395 SoC with 16 cores / 32 threads and powerful integrated Radeon 8060S graphics, 128GB of system memory, a nice 14-inch 2.8K display, and other top-end features to provide a dominating laptop powerhouse. In today's article are the very initial benchmarks of the AMD Ryzen AI Max+ PRO 395 Strix Halo SoC under Linux with a focus on the CPU capabilities: a separate article also out today is looking at the AMD Radeon 8060S graphics on Linux.

As shown in today's article the AMD Ryzen AI Max+ PRO 395 Linux performance is incredible with its 16 Zen 5 cores delivering staggering laptop / mobile workstation performance with a 55 Watt default TDP. But that's only half the magic of Strix Halo, with the other aspect being the very capable integrated RDNA 3.5 graphics with unified memory support. Given this being an equally interesting topic for Linux users considering a Strix Halo laptop or desktop, this article is centered around the integrated Radeon 8060S graphics support and performance under Linux.

At the end of April was the open-source surprise of NVIDIA posting Nouveau Linux driver patches for their Hopper and Blackwell GPUs. This comes to complement their official (open-source but out of tree) kernel driver support for these newer NVIDIA GPUs and in the absence of the modern Rust-based NOVA Linux kernel driver not being in working shape yet on the mainline kernel. An updated version of these Nouveau driver patches for NVIDIA Hopper and Blackwell GPUs were posted overnight...
