Po Canonicalu a SUSE oznámil také Red Hat, že bude podporovat a distribuovat toolkit NVIDIA CUDA (Wikipedie).
TrueNAS (Wikipedie), tj. open source storage platforma postavená na Linuxu, byl vydán ve verzi 25.10 Goldeye. Přináší NVMe over Fabric (NVMe-oF) nebo OpenZFS 2.3.4.
Byla vydána OpenIndiana 2025.10. Unixový operační systém OpenIndiana (Wikipedie) vychází z OpenSolarisu (Wikipedie).
České základní a střední školy čelí alarmujícímu stavu kybernetické bezpečnosti. Až 89 % identifikovaných zranitelností v IT infrastruktuře vzdělávacích institucí dosahuje kritické úrovně, což znamená, že útočníci mohou vzdáleně převzít kontrolu nad klíčovými systémy. Školy navíc často provozují zastaralé technologie, i roky nechávají zařízení bez potřebných aktualizací softwaru a používají k nim pouze výchozí, všeobecně známá

Letos byly uděleny pouze dvě medaile Za zásluhy o stát v oblasti hospodářské, druhou dostal informatik a manažer Ondřej Felix, který se zabývá digitalizací státní správy.
Tor Browser, tj. fork webového prohlížeče Mozilla Firefox s integrovaným klientem sítě Tor přednastavený tak, aby přes tuto síť bezpečně komunikoval, byl vydán ve verzi 15.0. Postaven je na Firefoxu ESR 140.
Bylo oznámeno (cs) vydání Fedora Linuxu 43. Ve finální verzi vychází šest oficiálních edic: Fedora Workstation a Fedora KDE Plasma Desktop pro desktopové, Fedora Server pro serverové, Fedora IoT pro internet věcí, Fedora Cloud pro cloudové nasazení a Fedora CoreOS pro ty, kteří preferují neměnné systémy. Vedle nich jsou k dispozici také další atomické desktopy, spiny a laby. Podrobný přehled novinek v samostatných článcích na stránkách Fedora Magazinu: Fedora Workstation, Fedora KDE Plasma Desktop, Fedora Silverblue a Fedora Atomic Desktops.
Elon Musk oznámil (𝕏) spuštění internetové encyklopedie Grokipedia (Wikipedia). Zatím ve verzi 0.1. Verze 1.0 prý bude 10x lepší, ale i ve verzi 0.1 je podle Elona Muska již lepší než Wikipedia.
PSF (Python Software Foundation) po mnoha měsících práce získala grant ve výši 1,5 milionu dolarů od americké vládní NSF (National Science Foundation) v rámci programu "Bezpečnost, ochrana a soukromí open source ekosystémů" na zvýšení bezpečnosti Pythonu a PyPI. PSF ale nesouhlasí s předloženou podmínkou grantu, že během trvání finanční podpory nebude žádným způsobem podporovat diverzitu, rovnost a inkluzi (DEI). PSF má diverzitu přímo ve svém poslání (Mission) a proto grant odmítla.
Balík nástrojů Rust Coreutils / uutils coreutils, tj. nástrojů z GNU Coreutils napsaných v programovacím jazyce Rust, byl vydán ve verzi 0.3.0. Z 634 testů kompatibility Rust Coreutils s GNU Coreutils bylo úspěšných 532, tj. 83,91 %. V Ubuntu 25.10 se již používá Rust Coreutils místo GNU Coreutils, což může přinášet problémy, viz například nefunkční automatická aktualizace.

g++. _GLIBCXX_NODISCARD je nejspíš atribut [[nodiscard]], _GLIBCXX20_CONSTEXPR je constexpr. Našel jsem třeba nějaký náhodný zdroják, kde (CTRL+F _GLIBCXX20_CONSTEXPR):
#ifndef _GLIBCXX20_CONSTEXPR # if __cplusplus > 201703L # define _GLIBCXX20_CONSTEXPR constexprTakže je otázka, proč ty tam tyhle definice nemáš (i když jinde se tam používají) a kompilátor tomu nerozumí. Zkus
g++ prostě přeinstalovat (a případně předtím ještě promazat ty hlavičkové soubory).
Diky moc, toto nakoniec nepriamo pomohlo.
Preinstalovat g++ nepomohlo - ale mas dobry postreh a vsimol si si, ze mam premiesane hlavickove subory. Tak som odinstaloval libgcc-8-dev a libgcc-7-dev (a vsetko, co na tom zaviselo) a kompilacia uz ide.
