Blender 5.1 is out today with many exciting improvements for this leading open-source 3D modeling software. From AMD GPU hardware ray-tracing being enabled by default at long last to more mature Vulkan support and performance, Blender 5.1 is a great release...

Intel Graphics Compiler 2.30.1 is now available for this LLVM/Clang-based compiler stack used by the Compute Runtime on Linux and under Windows is used both for graphics and compute...

Intel today announced their Core Ultra 200HX Plus series mobile processors as their refresh for Arrow Lake HX. The announcement of the Core Ultra 200HX Plus also mentions a new Intel Binary Optimization Tool software package that has the potential of being quite interesting...

Open-source developer Andy Nguyen recently demonstrated porting Linux to the Sony PlayStation 5. The PS5 notably uses a custom AMD SoC and with some patches is able to play nicely with the open-source AMD graphics driver stack...

A patch posted today to the Linux kernel mailing list provides an ARM64-optimized CRC64-NVMe implementation for nearly a 6x improvement on modern Arm SoCs...

The jemalloc memory allocator "malloc" implementation has been popular for HPC and server use down to desktop use in apps like Firefox. Jemalloc has proven over the years to be effective on delivering better performance and scalability while enjoying lower memory usage and less fragmentation than alternative malloc implementations. Meta recently announced that they are renewing their investment into jemalloc...

An interesting Linux detail from today's NVIDIA GTC 2026 kickoff is that Canonical will be integrating NVIDIA's DOCA-OFED software framework into the Ubuntu Linux archive for leveraging the high-speed networking stack for HPC and AI...

Ve třetím článku o vývoji programů pro osmibitové počítače Atari si popíšeme základy použití maker v assembleru CA65. Vytvoříme příklad pro výpis dvouciferné hexadecimální hodnoty a zmíníme se o triku s instrukcí RTS.

A bit of time has passed since having any exciting performance improvements to report on within the GNU C Library "glibc" but that changed today with another nice x86_64 optimization for modern CPUs...

FFmpeg 8.1 is out today as the newest stable release of this widely-used, open-source multimedia library...

The Linux kernel's extensible scheduler class "sched_ext" to allow for custom CPU scheduling policies as BPF programs continues enabling new functionality. Queued up in the sched_ext development code ahead of next month's Linux 7.1 cycle is the new SCX_ENQ_IMMED capability for enabling tighter control over when tasks land on a CPU...

Since last week's Fedora 44 Beta release I have been testing out this upcoming Fedora Linux version on a few systems in the lab, most notably with the Framework Desktop powered by the powerful AMD Ryzen AI Max+ 395 "Strix Halo". Fedora Workstation 44 Beta has been looking nice and running stable albeit in some instances seeing lower performance at this point than Fedora Workstation 43 but overall in good shape.

The past several years Imagination Tech has been investing in an upstream and open-source DRM kernel graphics driver as well as a PowerVR Vulkan driver in Mesa. Their Mesa focus has exclusively been on the PowerVR Vulkan driver with the plans all along to use the Zink generic OpenGL-on-Vulkan implementation. With next quarter's Mesa 26.1 release, that goal is being realized with Zink now working nicely atop the PowerVR Vulkan driver for in turn achieving open-source OpenGL support on PowerVR...

A round of Intel graphics driver updates were sent today to DRM-Next in staging ahead of April's Linux 7.1 merge window. The changes in this pull aren't too particularly exciting with a lot of code refactoring and other work, but there are preparations made for supporting UHBR DP tunnels...

The work by Derek Clark on enhancing the Lenovo Legion Go gaming handheld support for Linux continues panning out nicely. The latest driver effort, the creation of the Lenovo Legion Go and Go S Series HID Drivers to help with controller configuration, is set to be introduced in Linux 7.1...

The upcoming Linux 7.1 kernel cycle is set to retire UDP-Lite support. The UDP-Lite protocol allowed for partial checksums where potentially damaged/corrupted packets are still delivered to the application. Since the Linux 2.6.20 days there has been UDP-Lite support but the kernel is now set to retire it given breakage that has persisted for years and cleaning up the networking code can yield a performance advantage for non-UDP-Lite users...

A four year old optimization idea for the RADV driver was scratched off the TODO list last week for next quarter's Mesa 26.1 release...

Last week yet more AMDGPU kernel graphics driver updates were submitted to DRM-Next ahead of the Linux 7.1 merge window happening in April...

Podíváme se na zásah Mety proti scamovým centrům, rozklad sítě SocksEscort, mezinárodní odstavení škodlivé infrastruktury, dvě aktivně zneužívané chyby v Chromu i levnější cestu k vlastním malwarům.
