Armbian, tj. linuxová distribuce založená na Debianu a Ubuntu optimalizovaná pro jednodeskové počítače na platformě ARM a RISC-V, ke stažení ale také pro Intel a AMD, byl vydán ve verzi 25.8.1. Přehled novinek v Changelogu.
Včera večer měl na YouTube premiéru dokumentární film Python: The Documentary | An origin story.
Společnost comma.ai po třech letech od vydání verze 0.9 vydala novou verzi 0.10 open source pokročilého asistenčního systému pro řidiče openpilot (Wikipedie). Zdrojové kódy jsou k dispozici na GitHubu.
Ubuntu nově pro testování nových verzí vydává měsíční snapshoty. Dnes vyšel 4. snapshot Ubuntu 25.10 (Questing Quokka).
Řada vestavěných počítačových desek a vývojových platforem NVIDIA Jetson se rozrostla o NVIDIA Jetson Thor. Ve srovnání se svým předchůdcem NVIDIA Jetson Orin nabízí 7,5krát vyšší výpočetní výkon umělé inteligence a 3,5krát vyšší energetickou účinnost. Softwarový stack NVIDIA JetPack 7 je založen na Ubuntu 24.04 LTS.
Národní úřad pro kybernetickou a informační bezpečnost (NÚKIB) spolu s NSA a dalšími americkými úřady upozorňuje (en) na čínského aktéra Salt Typhoon, který kompromituje sítě po celém světě.
Společnost Framework Computer představila (YouTube) nový výkonnější Framework Laptop 16. Rozhodnou se lze například pro procesor Ryzen AI 9 HX 370 a grafickou kartu NVIDIA GeForce RTX 5070.
Google oznamuje, že na „certifikovaných“ zařízeních s Androidem omezí instalaci aplikací (včetně „sideloadingu“) tak, že bude vyžadovat, aby aplikace byly podepsány centrálně registrovanými vývojáři s ověřenou identitou. Tato politika bude implementována během roku 2026 ve vybraných zemích (jihovýchodní Asie, Brazílie) a od roku 2027 celosvětově.
Byla vydána nová verze 21.1.0, tj. první stabilní verze z nové řady 21.1.x, překladačové infrastruktury LLVM (Wikipedie). Přehled novinek v poznámkách k vydání: LLVM, Clang, LLD, Extra Clang Tools a Libc++.

. Nejsem ale u toho serveru fyzicky a ten tunner tam nemám zapojený, dá se nějak zjistit, jestli je ten driver už k dispozoci? A ještě bych se chtěl zeptat, jestli když vyjde nový kernet, jestli se mi vč. headers nabídne při apt-get update && apt-get upgrade
automaticky, nebo vždy budu muset instalovat ručně? Mockrát díky.

Vzhledem k tomu, že Ubuntu vychází z Debianu, nemyslím si, že by pro (nic ve zlém) odborníky jako jsi ty, neměl být problém rozjet tunner se stejnou funkcionalitou i na Debianu. Napadá tě, jak bych to tedy mohl rozjet? Všechno, co jsem zkoušel, jsem už tady zmínil.

Ale malo by to ísť nejak upraviť, no ja sa v tých "čudných" znakoch jaksi strácam.
