Earlier this week I delivered the results of our largest-ever GCC vs. LLVM Clang Linux x86_64 compiler comparison with a dozen systems from various generations of Intel and AMD CPUs and using 62 benchmarks tested on GCC 8/9 and Clang 7/8 releases. In this article the compiler performance is being looked at for the IBM POWER9 architecture with the benchmarks done on a Raptor Computing Systems Talos II workstation running Ubuntu Linux.

Beyond the FOSDEM conference itself this past week in Brussels, GNOME developers also used the occasion once again for hosting a developer "hackfest" as they prepare for the home stretch in GTK 4.0 development...

Several System76 laptops are beginning to see Coreboot support! This is a nice sign of progress in making System76 hardware more attractive to Linux/open-source users though they aren't yet shipping Coreboot on the systems by default...

Developers working on the "Gallium Nine" Direct3D 9 state tracker are working on supporting the NIR intermediate representation as an alternative option to the default TGSI IR used traditionally by Gallium3D drivers. In supporting NIR, Gallium Nine opens up to some interesting new possibilities...

Formerly known as Intel GPU Tools, the scope of "IGT" has been expanding now for providing tools and functionality testing not only around the Intel DRM/KMS driver but also the other mainline Linux display drivers...

The GCC 9.1.0 release as the first stable version of GCC 9 is stabilizing at a rate where it should debut by/around April. For those sticking to the GCC 8 series a bit longer, the GCC 8.3.0 compiler update is also on the way...

[čtení do minuty] The Document Foundation vydala novou verzi kancelářského balíku LibreOffice 6.2. Na první pohled si všimnete upraveného vzhledu, přepnout můžete na NotebookBar, vylepšila se práce s tabulkami a animacemi.

KiCad remains the leading open-source electronic design suite for PCB design and other features. KiCad had a successful 2018 with the software even being used by System76 as part of the daughter board PCB designs with Thelio desktop computer, but looking ahead the developers are still working towards version 6.0...

Besides the ZFS file-system just being a heck of a lot better all-around than FreeBSD's traditional UFS, tooling around ZFS paired with its native snapshot capabilities is allowing for more resilient installations and upgrades of FreeBSD...

[6 minut čtení] Linuxbrew je port populárního macovského Homebrew. Oba projekty byly v nejnovější verzi spojeny, takže si alternativních balíčků můžeme užít i v Linuxu. Nebudeme k tomu potřebovat ani práva roota, protože se instaluje do domovského adresáře. Původním autorem projektu Homebrew je Max Howell, který balíčkovací systém pro macOS (tehdy ještě Mac OS X) v jazyce Ruby vytvořil v roce 2009. Přinášel do prostředí jablečných počítačů to, co známe z linuxového světa: pohodlný balíčkovací systém, který na jeden příkaz nainstaluje nový balíček včetně všech závislostí. Také proto projekt používá slogan Chybějící správce balíčků pro macOS.

With today's launch benchmarks of the AMD Radeon VII graphics card on Linux, tests were done using the latest Linux 5.0 Git kernel as well as Mesa 19.0 providing the OpenGL/Gallium3D drivers. Details on the support going back to older releases were covered, but in this article is looking at the performance difference between those recent Linux kernel and Mesa releases.

The Free Software Foundation (FSF) has certified the Vikings D8 motherboard and D8 workstation as they "Respect Your Freedom" as the newest endorsed hardware...

With the upcoming Linux 5.0 kernel release there is initial support for Adiantum and implemented within the fscrypt file-system encryption framework in Google's pursuit to offering more viable data encryption on low-end Android devices...

For those uncomfortable in building your own Linux kernel and Mesa in order to attain Radeon VII support (or don't want to leverage third-party package repositories), there is a new Radeon Software for Linux driver release now available with Radeon VII support...

Today we can finally reveal the Linux performance details for the AMD Radeon VII graphics card... Especially if you are an open-source driver fan, it's quite a treat thanks to having fully open-source and fairly mature driver support, but can this $699 USD graphics card dance with the likes of the GeForce RTX 2080? Here is our initial look at the Radeon VII performance on Linux using fifteen different AMD Radeon and NVIDIA GeForce graphics cards for both OpenCL compute and Vulkan/OpenGL gaming on Ubuntu Linux.

The boot experience may be improved moving forward for AMDGPU-using Radeon Linux users...

If Microsoft Office 2019 isn't your thing, The Document Foundation is today debuting LibreOffice 6.2 as the latest major release for this cross-platform, open-source office suite...

[čtení do minuty] Tým za populárním jednodeskovým počítačem Raspberry Pi otevřel první kamenný obchod v britském Cambridge, kde malina vznikla. Koupíte tu základní sady pro začínající uživatele, ale i spoustu doplňků.

Well known AMD open-source OpenGL driver developer Marek Olšák has published an interesting new patch series for RadeonSI that can help boost the performance of this Gallium3D driver in select cases...
