Byla vydána nová stabilní verze 24.05 linuxové distribuce NixOS (Wikipedie). Její kódové označení je Uakari. Podrobný přehled novinek v poznámkách k vydání. O balíčky se v NixOS stará správce balíčků Nix.
Byla vydána nová verze 1.48.0 sady nástrojů pro správu síťových připojení NetworkManager. Novinkám se v příspěvku na blogu NetworkManageru věnuje Fernando F. Mancera. Mimo jiné se v nastavení místo mac-address-blacklist nově používá mac-address-denylist.
Před 25 lety, 31. května 1999, započal vývoj grafického editoru Krita (Wikipedie). Tenkrát ještě pod názvem KImageShop a později pod názvem Krayon.
Farid Abdelnour se v příspěvku na blogu rozepsal o novinkám v nejnovější verzi 24.05.0 editoru videa Kdenlive (Wikipedie). Ke stažení brzy také na Flathubu.
David Revoy, autor mj. komiksu Pepper&Carrot, se rozepsal o své aktuální grafické pracovní stanici: Debian 12 Bookworm, okenní systém X11, KDE Plasma 5.27, …
Wayland (Wikipedie) byl vydán ve verzi 1.23.0. Z novinek lze vypíchnout podporu OpenBSD.
Craig Loewen na blogu Microsoftu představil novinky ve Windows Subsystému pro Linux (WSL). Vypíchnout lze GUI aplikaci pro nastavování WSL nebo správu WSL z Dev Home.
V sobotu 1. června lze navštívit Maker Faire Ostrava, festival plný workshopů, interaktivních činností a především nadšených a zvídavých lidí.

kernel: usb 2-1.3: cannot submit urb 0, error -28: not enough bandwidthTo vypadá jak kdyby usb port neměl dostatečnou rychlost. No když mikrofon vyměním za starou usb flešku, tak to z ní čte rychlostí přes 30MB/s což mnohonásobně převyšuje bitrate mono audia z mikrofonu. Taky mám usb zvukovku a ta funguje bezproblému ve všech portech. Neřekl bych, že bude problém v mikrofonu, protože ten před výměnou desky fungoval. Stará deska: DFI LANParty JR P45 T2RS Nová deska: supermicro X10SAE mikrofon: maono AU-PM461TR Distro: Archlinux.

V modrých usb3 portech jsou zvukovka a mikrofon. Mi přijde, že se ta rychlost nějak dynamicky mění podle toho co se tam strčí. U flešek to ukazuje 480M, u klávesnice 12M, u myši jenom 1.5M
EHCI1 Select Enabled to enable EHCI (Enhanced Host Controller Interface) Controller 1 for USB 2.0 support. One EHCI controller must always be enabled. The settings are Enabled and Disabled. EHCI2 Select Enabled to enable EHCI (Enhanced Host Controller Interface) Controller 2 for USB 2.0 support. One EHCI controller must always be enabled. The settings are Enabled and Disabled.Potom je tam pár voleb které moc nechápu. Když jsem je zkoušel měnit, tak jsem dosáhl akorát toho, že mi nešlo zadat heslo k šifrovanýmu disku, nebo mi nebootaly USB flešky. Vliv na USB mikrofon to nemělo žádný.
Legacy USB Support This feature enables support for legacy USB devices. Select Auto to disable legacy support if USB devices are not present. Select Disable to have USB devices available only for EFI applications. The options are Enabled, Disabled and Auto. Port 60/64 Emulation This feature enables or disables I/O port 60h/64h emulation support. This should be enabled for complete USB keyboard legacy support for non-USB-aware operating systems. The options are Disabled and Enabled. XHCI Hand-Off This item is a work-around solution for operating systems that do not support XHCI (Extensible Host Controller Interface) hand-off. The XHCI ownership change should be claimed by the XHCI driver. The settings are Enabled and Disabled. EHCI Hand-Off This item is for Operating Systems that do not support Enhanced Host Controller Interface (EHCI) hand-off. When this item is enabled, EHCI ownership change will be claimed by the EHCI driver. The settings are Enabled and Disabled. XHCI Mode This feature handles the operation mode for the XHCI (Extensible Host Controller Interface) controller. The settings are Smart Auto, Auto, Enabled, Disabled and Manual.Mám to všesko na Enabled kromě toho posledního XHCI Mode. Vlastně ani USB3 nijak zvlášť nepotřebuju, nemám nic co by tu rychlost dokázalo využít. Ješte mě tak napadá jedna věc. Deska má napájení k procesoru 8pin ale zdroj do tu mám, má vývod jenom 1x4pin. Říkal jsem si, že když má ten xeon TDP jenom 80W musí mu přece 4 piny stačit. Nějakou nestabilitu ani v maximální zátěži nepozoruju. Nemohlo by ten bordel s USB způsobovat toto?
XHCI Mode = Enabled
