Flowblade 2.20 is out this morning as the newest feature update to this open-source, non-linear video editing system for Linux...

Building off yesterday's Linux 6.14 release, the GNU Linux-libre 6.14-gnu downstream is now available for this flavor of the Linux kernel that strips out support for hardware/drivers depending upon non-open-source firmware/microcode as well as the ability to load proprietary kernel modules and other tainted code...

The GRUB bootloader saw a set of 73 patches last month for addressing a variety of security flaws that were discovered...

V dnešním článku dokončíme návrh ISA procesoru MB5016. Popíšeme si jednotlivé skupiny instrukcí budeme se zabývat obsluhou přerušení a výjimek, včetně příslušných registrů a instrukcí.

Dnes se budeme zabývat vektorizací smyček, v nichž se zpracovávají pole (vektory), což vyžaduje instrukce SSE2 nebo AVX. Důležité bude taktéž zjištění, jak je vektorizován přístup k prvkům pole s volitelným krokem (stride).

GIMP 3.0 was 7+ years in development before releasing as stable last week for this much anticipated, GTK3-ported image manipulation program update. Thankfully we're not seeing any lengthy periods of time for new bug-fix releases with today already marking the release of GIMP 3.0.2...

Last month Bcachefs lead developer Kent Overstreet talked of Bcachefs getting to the point of freezing its on-disk format with future on-disk format updates slated to be optional. With today's Bcachefs pull request for Linux 6.15, it's now being treated as "soft frozen" and also landing other new features for this copy-on-write file-system. Among the new features is case insensitive file/folder support contributed by Valve...

David Sterba of SUSE sent in all of the Btrfs file-system updates today for the now-open Linux 6.15 kernel merge window. There are some new performance optimizations, new and faster Zstd compression level options, and other changes slated to be included for this CoW file-system in Linux 6.15...

Assuming no objections from Linus Torvalds, the now open Linux 6.15 merge window could introduce a brand new subsystem: fwctl...

An AMD engineer has landed experimental support within the LLVM codebase for building Flang-RT on GPUs. Flang-RT being the run-time for LLVM's modern Fortran "Flang" compiler and in turn this effort working to allow more Fortran code to easily run on GPUs with capable LLVM back-ends...

There was a hiccup yesterday with no Linux 6.14 release or 6.14-rc8 otherwise... Linus Torvalds has a very good track record of sticking to his Sunday release regiment. Yet yesterday was quiet. Today though Linus Torvalds released the Linux 6.14 kernel as the newest stable version. Linux 6.14 is what's set to go on and power Ubuntu 25.04, Fedora 42, and other spring 2025 Linux distribution releases...

What a week. Last week Intel published a new AVX10 whitepaper where they dropped the optional 512-bit support of AVX10.2 and confirmed future P and E cores will have AVX10.2-512 support unconditionally. A very welcome change by Intel albeit late in rushing to get patches out to change that behavior ahead of the GCC 15 stable compiler release as well as working similar changes into the LLVM Clang compiler. As of today those GNU Compiler Collection patches have been merged to prepare for AVX10.2 always having 512-bit support available...

Among the early pull requests submitted in advance of the Linux 6.14 stable release and in turn the Linux 6.15 merge window opening were the x86 FPU updates. Notable this round are faster x86/x86_64 encryption/decryption performance for both Intel and AMD processors as well as beginning to land the kernel-side changes needed to support Intel Advanced Performance Extensions (APX)...

With the FreeDesktop.org GitLab infrastructure getting back up, Wayland Protocols 1.42 was released today as the newest version of this official set of protocols for Wayland compositors...

While we are still awaiting the Linux 6.14 release (or a 6.14-rc8 release) with no kernel drop having occurred on Sunday, early pull requests for the Linux 6.15 kernel cycle continue flowing in. Among the early pull requests over the weekend were the CRC code updates that include some nice optimizations for those running on AVX-512 processors...

Libinput 1.28 debuted today by Red Hat's input expert Peter Hutterer. With this updated input handling library used by both Wayland and X.Org Server environments there is now support for three-finger drag on touchpads...

Raspberry Pi's brisk pace of new hardware and software the past few months continues today... The Raspberry Pi PoE+ Injector was announced today at the $25 USD price point...

V dnešním díle Postřehů se podíváme na dlouho využívanou zranitelnost souborů LNK ve Windows, snahy o snížení evropské závislosti na USA v oblasti IT nebo údajnou ruskou podporu ransomwarové skupiny Black Basta.

Vyšla nová verze prostředí GNOME 48 s řadou nových funkcí a vylepšení uživatelského rozhraní. EU OS je nová komunitně řízená alternativa Linuxu pro evropský veřejný sektor.

The EROFS open-source, read-only Linux file-system is set to be extended with the upcoming Linux 6.15 kernel cycle to support massive amounts of data to support AI model training...
