Provozovatel čínské sociální sítě TikTok dostal v Evropské unii pokutu 530 milionů eur (13,2 miliardy Kč) za nedostatky při ochraně osobních údajů. Ve svém oznámení to dnes uvedla irská Komise pro ochranu údajů (DPC), která jedná jménem EU.

Společnost JetBrains uvolnila Mellum, tj. svůj velký jazykový model (LLM) pro vývojáře, jako open source. Mellum podporuje programovací jazyky Java, Kotlin, Python, Go, PHP, C, C++, C#, JavaScript, TypeScript, CSS, HTML, Rust a Ruby.
Vývojáři Kali Linuxu upozorňují na nový klíč pro podepisování balíčků. K původnímu klíči ztratili přístup.
V březnu loňského roku přestal být Redis svobodný. Společnost Redis Labs jej přelicencovala z licence BSD na nesvobodné licence Redis Source Available License (RSALv2) a Server Side Public License (SSPLv1). Hned o pár dní později vznikly svobodné forky Redisu s názvy Valkey a Redict. Dnes bylo oznámeno, že Redis je opět svobodný. S nejnovější verzí 8 je k dispozici také pod licencí AGPLv3.
Oficiální ceny Raspberry Pi Compute Modulů 4 klesly o 5 dolarů (4 GB varianty), respektive o 10 dolarů (8 GB varianty).
Byla vydána beta verze openSUSE Leap 16. Ve výchozím nastavení s novým instalátorem Agama.
Devadesátková hra Brány Skeldalu prošla portací a je dostupná na platformě Steam. Vyšel i parádní blog autora o portaci na moderní systémy a platformy včetně Linuxu.
Lidi dělají divné věci. Například spouští Linux v Excelu. Využít je emulátor RISC-V mini-rv32ima sestavený jako knihovna DLL, která je volaná z makra VBA (Visual Basic for Applications).
Revolut nabídne neomezený mobilní tarif za 12,50 eur (312 Kč). Aktuálně startuje ve Velké Británii a Německu.
