Svobodný software

Minule jsme spustili základní infrastrukturu pro běh našich služeb. Nyní se podíváme na dva nástroje, které nám společně zajistí bezpečné zálohování. Kopia pořídí snímek dat a Rclone vše přesune do úložiště.

Popíšeme si VBI, tedy Vertical Blank Interrupt. Jde o subrutiny volané po dokončení vykreslování snímku, či na začátku vykreslování dalšího snímku. Mnohé hry mají své jádro (kernel) implementované právě přímo ve VBI.

Since Intel Meteor Lake has been the Intel Silicon Security Engine to serve as a silicon root-of-trust for secure firmware loading, boot measurements, and similar functionality. This Intel Silicon Security Engine has been built on with Lunar Lake and Panther Lake as well as set to take on more importance with future Intel hardware platforms. We are now seeing a Linux driver come for this silicon RoT with the Intel Silicon Security Engine Interface (ISSEI)...

Following last week's disclosure of the Dirty Frag vulnerability for the Linux kernel, which only finished being patched up in mainline on Monday, Fragnesia is now public as a similar local privilege escalation (LPE) vulnerability...

GCC 16.1 released at the end of April as the latest major, annual feature release to the GNU Compiler Collection. Early benchmarks showed some nice leads for GCC 16 over GCC 15. Continued testing of the new GCC 16 compiler has continued to show overall better performance of the resulting binaries than using GCC 15 on the same hardware and same compiler flags. That led many to wonder about the GCC 16 performance up against the latest LLVM/Clang open-source compiler, which is the focus of today's benchmarking showdown.

Intel on Tuesday released a new version of their open-source Compute Runtime for OpenCL and Level Zero support across their integrated and discrete graphics hardware...

Discord, the popular instant messaging and VoIP communication platform, announced some significant improvements being made to their Linux client...

In addition to FreeBSD 15.1 releasing in the coming weeks, NetBSD 11.0 is also just around the corner as another prominent and major BSD update. NetBSD 11.0-RC4 is now available for last minute testing with this hoping to be the final release candidate...

KDE today announced a significant investment into the project by Germany's Sovereign Tech Fund. KDE will be receiving €1,285,200 EUR (or roughly 1.5 million USD) over the years 2026 and 2027 to make some significant improvements into their software stack...

A new core infrastructure improvement for the Linux kernel on ARM being worked on is enabling 128-bit page table entries (PTEs) with FEAT_D128 as a new optional feature of Armv9.3 and later...

Wine's Wayland native driver has taken another step forward with now supporting the pointer warp "wp_pointer_warp_v1" protocol...

For those making use of OpenZFS on Linux or FreeBSD, OpenZFS 2.4.2 is out today as the newest stable release of this ZFS file-system implementation...

Jeden známý okomentoval můj kód psaný v Pythonu slovy: „kdy to dokončíš, aby to šlo spustit?“ Vysvětlilo se, že myslí výpustky („trojtečky“, …), které jsem použil. Ve skutečnosti hrají v Pythonu důležité role.

Vytvoříme virtuální USB zařízení ovládaná přes IP, prověříme skutečnou bezpečnost svých hesel, bleskově spustíme vývojářské projekty a optimalizujeme výkon i spotřebu procesoru na Linuxu.

FreeBSD 15.0 had aimed to provide a KDE desktop install option from its text-based OS installer to make for a more compelling FreeBSD out-of-the-box desktop experience. That was then delayed to FreeBSD 15.1 but that didn't end up materializing. Now the KDE desktop install option is diverted to FreeBSD 15.2...

Today's Patch Tuesday is a busier one than normal for the quarter. Both AMD and Intel have rolled out new updates for Linux customers among other security disclosures today. Thankfully though the vulnerabilities don't appear to be too widespread or impactful...

DXVK-NVAPI 0.9.2 is now available for this implementation of NVIDIA's NVAPI/NVOFAPI interfaces atop DXVK and VKD3D-Proton that is used in turn by Valve's Steam Play (Proton) for enhanced NVIDIA Linux gaming support...

An IBM engineer posted the first set of patches enabling the Rust programming language support for the Linux kernel to be built on the s390 architecture...

It's been nearly one year to the week since Intel introduced Project Battlematrix as their initiative for improving their Linux driver support for the Arc Pro B-Series with enhancements such as bettering the multi-GPU support in allowing up to eight Arc Pro GPUs per system as well as other open-source driver optimizations in the era of AI. Recently with the Arc Pro B70 in having four review samples for testing I was finally able to try out the multi-GPU state of the Arc (Pro) graphics cards on Linux with their open-source driver code.

A new driver expected to land in the upcoming Linux 7.2 kernel is the ARCTIC Fan Controller driver to allow fan speed monitoring and PWM controls for this upcoming ARCTIC product. Making this new driver all the more exciting is that it was worked on by ARCTIC directly compared to the typical workflow for such desktop/consumer hardware peripherals often being left up to the reverse-engineering, open-source community...
