Sny o designu GNOME Shellu, článek s náhledy a videi, představuje dlouhodobou vizi týmu GNOME pro vylepšení uživatelského rozhraní GNOME Shellu. Zatímco nedávné verze přinášely spíše drobné úpravy, designéři nyní plánují zásadnější změny.
Byla vydána nová verze 10.5 sady aplikací pro SSH komunikaci OpenSSH. Přináší řadu důležitých bezpečnostních oprav, vylepšení funkcí a oprav chyb. Nově vyžaduje podporu ECC (Elliptic Curve Cryptography) v libcrypto, včetně křivky NISTP521.
Byla vydána nová verze 10.6 z Debianu vycházející linuxové distribuce DietPi pro (nejenom) jednodeskové počítače. S novými obrazy pro Orange Pi 4 Pro, Orange Pi Zero 3W a Odroid M1/M1S/M2. Přehled novinek v poznámkách k vydání.
Námořní drony používané elitními jednotkami britského královského námořnictva tajně posílaly údaje do Číny. Stroje vybavené čínskými komponenty měly být využívány pro vojenské operace na Blízkém východě. Kamery na dálkově řízených průzkumných člunech K3 Scout byly vybavené součástkami, které bez vědomí britského námořnictva odesílaly informace do spojeného zařízení v Číně. Britské námořní síly využívaly flotilu námořních dronů

V Linuxu v KVM byla nalezena a v upstreamu již byla opravena kritická zranitelnost Zapscape aneb CVE-2026-64561. Root na hostovaném počítači (virtuální stroj) může obejít izolaci a získat plnou kontrolu nad hostitelským systémem (DoS útok nebo vzdálené spuštění kódu s právy roota). Na obou hlavních architekturách – Intel i AMD. Zranitelnost v Linuxu existovala 6 let (od července 2020 do července 2026).
Počítačová hra Knytt napsaná v Multimedia Fusion 2 byla vydána před 20 lety. Při této příležitosti byl dnes představen moderní port (YouTube) této plošinovky na současné operační systémy pod názvem Knytt Classic. Je zdarma k dispozici na Steamu a GOG.com.
Americká technologická společnost Meta Platforms představila nový model umělé inteligence (AI) Muse Glimmer. Model je menší než přední modely AI od konkurence a má běžet přímo na počítačích uživatelů. Meta model zpřístupní jako open source, tedy otevřený software. Nový model je navržen tak, aby zvládal takzvané agentní úkoly na počítačích se spotřebitelskou grafickou kartou. Klade si tak za cíl uspokojit poptávku po systémech AI, které běží přímo na zařízeních uživatelů.
