Clear Linux Squeezed Out More Open-Source Performance In 2020

Phoronix - 11. Leden 2021 - 18:37
Here is a look at how the performance of Intel's Clear Linux compares for the end of 2020 against the end of 2019 and 2018 on the same hardware platform for looking at the Intel performance optimizations made to this open-source Linux distribution. This was another year of Intel engineers making more headway on out-of-the-box Linux performance even though they have been less vocal about the project over the past year.

Postřehy z bezpečnosti: kryptoměny táhnou

Root.cz - 11. Leden 2021 - 0:00
[3 minuty čtení] Dnes se podíváme na nový malware ElectroRAT zaměřený na uživatele kryptoměn, dále na nedokumentovaný privilegovaný účet v zařízeních Zyxel, na novou vlnu vyděračských e-mailů a na apokalyptický souboj dvou nástrojů od Google. Bezpečnostní pracovníci odhalili malware nazývaný „ElectroRAT”, který se zaměřuje na uživatele kryptoměn. Kampaň s cílem rozšířit daný malware mezi velké množství uživatelů různých operačních systémů (Windows, Linux a macOS), probíhala od začátku ledna minulého roku. Malware je vytvořený pomocí open-source kódu „Electron“, jedná se o multiplatformní aplikační framework. Útočníci se snažili získat privátní klíče k uživatelským krypto peněženkám.

Changing One "If" To "While" Caused An Unexpected Shift In A Kernel Benchmark This Week

Phoronix - 10. Leden 2021 - 20:02
Several months back you may recall that Linux 5.9 kernel regression we noted that in turn was bisected to code introduced by Linus Torvalds around page lock fairness. That was ultimately worked out in time with allowing a control over the page lock (un)fairness to address the regressed workloads while being fair enough to satisfy his original change. But now this week for Linux 5.11, Linus Torvalds has again altered the behavior. It then ended up causing a PostgreSQL database server performance regression but fortunately any impact should be very minimal and hopefully not appearing in any real-world situation...

Linux Kernel Developers Discuss Dropping A Bunch Of Old CPUs

Phoronix - 10. Leden 2021 - 15:12
With Linux 5.10 having shipped as the latest Long Term Support (LTS) release to be maintained for at least the next five years, a discussion has begun over dropping a number of old and obsolete CPU platform support currently found within the mainline kernel. For many of the architectures being considered for removal they haven't seen any new commits in years but as is the case once proposals are made for them to be removed there are often passionate users wanting the support to be kept...

KDE Plasma 5.21 s kompletně přepsaným kompozitorem KWin, Firefox konečně s AVIF dekodérem

Root.cz - 10. Leden 2021 - 0:00
[5 minut čtení] Vyšel Linux Mint 20.1, Intel Haswell GPU GT1 už řadu měsíců nefunguje, práce reverznutí GPU Apple M1, Async Page Flipping i pro starší GPU Intel, Xbox i Playstation jsou u 4k videa velmi hladové. Do projektu KDE se chystá jedna obří novinka. Jak víme z posledních let, vývoj kompozitoru KWin se poněkud loudal za vývojem doby – podpora Waylandu měla/má oproti GNOME určité zpoždění a stejné platilo či platí o dalších věcech jako podpoře HiDPI monitorů, podpoře mixů různých hodnot DPI na více monitorech a také podpoře různých obnovovacích frekvencí, zejména právě v kombinaci s Waylandem.
