Zaměříme se na instalaci a reálné zkušenosti s provozováním Sailfish OS na Xperii 10 III jakožto na primárním mobilním telefonu. Proč (ne)chtít Sailfish OS a na jakých zařízeních ho můžeme provozovat?

Sonda do světa otevřeného softwaru. Dnes si představíme aplikaci pro čištění nepotřebných souborů, vyzkoušíme emulátor chytrých hodinek Pebble, řekneme si o aplikace pro práci s barvami a představíme si prohlížeč logů.

While System76 has been hard at work on a redesigned Thelio desktop chassis design, this hasn't slowed down their software work. Today they shipped COSMIC Epoch 1.0.8 as the newest work on their open-source, Rust-based desktop environment used by their in-house Pop!_OS Linux distribution as well as found in other Linux distributions too...

D7VK is the open-source project that began implementing the Direct3D 7 APIs atop Vulkan and with time the scope expanded to include Direct3D 6 support as well as Direct3D 5 support. Out today is D7VK 1.4 for continuing to enhance the support for these older D3D versions on Vulkan under Linux...

Google Cloud recently launched their N4A series powered by their in-house Axion ARM64 processors. In that launch-day benchmarking last month was looking at how the N4A with Axion compared to their prior-generation ARM64 VMs powered by Ampere Altra. There were dramatic generational gains, but how does the N4A stand up to the AMD EPYC and Intel Xeon instances? Here are some follow-up benchmarks I had done to explore the N4A performance against the Intel Xeon N4 and AMD EPYC N4D series.

A change merged to upstream LLVM Git yesterday for LLVM 23 is moving AMD's HIP to using the new/modern offload driver by default. This aligns with a prior change for NVIDIA CUDA and already in place for OpenMP offloading too...

Rozšiřitelnost je základní a velmi důležitou součástí databáze PostgreSQL. V tomto článku bych chtěl popsat pár zajímavých technik, které používám při vývoji vlastního rozšíření plpgsql_check.

Moderní překladače při zpracování hodnot s plovoucí řádovou čárkou dodržují normu IEEE 754, a to včetně rozšíření této normy (IEEE 754–2008). To sice zajišťuje stabilitu, ale někdy je vhodné se od této normy odklonit.

Following yesterday's Linux 7.0-rc1 release, Linus Torvalds authored and merged a patch to get rid of the Linux kernel's WARN_ALL_UNSEEDED_RANDOM Kconfig option. While that option was added with good intentions, on some systems it can yield a lot of unnecessary kernel log spam...
