Man Yue Mo z GitHub Security Lab se podrobně rozepsal o již opravené zranitelnosti CVE-2023-6241 v Arm Mali GPU umožňující získání roota na telefonu Pixel 8 s povoleným MTE (Memory Tagging Extension).
V San José probíhá vývojářská konference NVIDIA GTC 2024. CEO společnosti NVIDIA Jensen Huang měl dvouhodinovou keynote, ve které představil celou řadu novinek: NVIDIA Blackwell platform, NVIDIA NIM microservices, NVIDIA Omniverse Cloud APIs, Project GR00T, …
Byly zpracovány a na YouTube zveřejněny videozáznamy jednotlivých přednášek z letošního Installfestu.
Od 21. do 23. března proběhnou Arduino Days 2024. Sledovat bude možné oficiální streamy. Zúčastnit se lze i lokálních akcí. V Česku jsou aktuálně registrovány dvě: v Praze na Matfyzu a v Poličce v městské knihovně.
Letošní ročník konference LinuxDays se uskuteční o víkendu 12. a 13. října, opět se potkáme v pražských Dejvicích na FIT ČVUT. Také během letošního ročníku nás budou čekat desítky přednášek, workshopy, stánky a spousta doprovodného programu. Aktuální dění můžete sledovat na Twitteru, Facebooku nebo na Mastodonu, přidat se můžete také do telegramové diskusní skupiny.
Byla vydána nová major verze 2.0.0 a krátce na to opravné verze 2.0.1 open source online editoru Etherpad (Wikipedie) umožňujícího společné úpravy v reálném čase.
Matematický software GNU Octave byl vydán ve verzi 9.1.0. Podrobnosti v poznámkách k vydání. Nově je preferovaný grafický backend Qt a preferovaná verze Qt 6. V tomto vydání byly přepracovány funkce pro převod čísel z desítkové soustavy. Jako obvykle jsou zahrnuta také výkonnostní vylepšení a zlepšení kompatibility s Matlabem.
Společnost PINE64 stojící za telefony PinePhone nebo notebooky Pinebook publikovala na svém blogu březnový souhrn novinek. Vypíchnout lze, že pracují na virtuálním asistentu PineVox a zatím bezejmenných sluchátkách na lícní kosti (bone conduction).
Hyprland, kompozitor pro Wayland zaměřený na dláždění okny a zároveň grafické efekty, je již dva roky starý. Při té příležitosti byla vydána verze 0.37.0 (a záhy opravná 0.37.1 řešící chybu ve vykreslování oken). Nově závisí na knihovně hyprcursor, která poskytuje škálovatelné kurzory myši.
