Raspberry Pi Connect, tj. oficiální služba Raspberry Pi pro vzdálený přístup k jednodeskovým počítačům Raspberry Pi z webového prohlížeče, byla vydána v nové verzi 2.5. Nejedná se už o beta verzi.
Google zveřejnil seznam 1272 projektů (vývojářů) od 185 organizací přijatých do letošního, již jednadvacátého, Google Summer of Code. Plánovaným vylepšením v grafických a multimediálních aplikacích se věnuje článek na Libre Arts.
Byla vydána (𝕏) dubnová aktualizace aneb nová verze 1.100 editoru zdrojových kódů Visual Studio Code (Wikipedie). Přehled novinek i s náhledy a videi v poznámkách k vydání. Ve verzi 1.100 vyjde také VSCodium, tj. komunitní sestavení Visual Studia Code bez telemetrie a licenčních podmínek Microsoftu.
Open source platforma Home Assistant (Demo, GitHub, Wikipedie) pro monitorování a řízení inteligentní domácnosti byla vydána v nové verzi 2025.5.
OpenSearch (Wikipedie) byl vydán ve verzi 3.0. Podrobnosti v poznámkách k vydání. Jedná se o fork projektů Elasticsearch a Kibana.
PyXL je koncept procesora, ktorý dokáže priamo spúštat Python kód bez nutnosti prekladu ci Micropythonu. Podľa testov autora je pri 100 MHz približne 30x rýchlejší pri riadeni GPIO nez Micropython na Pyboard taktovanej na 168 MHz.
Grafana (Wikipedie), tj. open source nástroj pro vizualizaci různých metrik a s ní související dotazování, upozorňování a lepší porozumění, byla vydána ve verzi 12.0. Přehled novinek v aktualizované dokumentaci.
Raspberry Pi OS, oficiální operační systém pro Raspberry Pi, byl vydán v nové verzi 2025-05-06. Přehled novinek v příspěvku na blogu Raspberry Pi a poznámkách k vydání. Pravděpodobně se jedná o poslední verzi postavenou na Debianu 12 Bookworm. Následující verze by již měla být postavena na Debianu 13 Trixie.
Richard Stallman dnes v Liberci přednáší o svobodném softwaru a svobodě v digitální společnosti. Od 16:30 v aule budovy G na Technické univerzitě v Liberci. V anglickém jazyce s automaticky generovanými českými titulky. Vstup je zdarma i pro širokou veřejnost.
sudo-rs, tj. sudo a su přepsáné do programovacího jazyka Rust, nahradí v Ubuntu 25.10 klasické sudo. V plánu je také přechod od klasických coreutils k uutils coreutils napsaných v Rustu.

Restart jsem nezkoušel protože je poškozen login, mám obavy že server nenaběhne a jeho provoz je kritický.
Přihlašuji se pomocí ssh.
V logu jsem nic nenašel jen chyby disku, ale myslím, že ty souvisí s poškozenými soubory ne se samotným HW.

Prosím o jakýkoliv nápad na řešení jak se zbavit chybných souborů
Děkuji za jakoukoliv přínosnou pomoc.
Ja si naopak myslim, ze mate HW problem, ktery s nejvetsi pravdepodobnosti zpusobuje problemy s filesystemem. Rozhodne bych se podival na podrobnosti ve SMARTu disku.
Tak si mount a dalsi utility nakopirujte z jineho stroje treba do /root/ a spoustejte je tam.
Soubory nejspis nemuzete smazat proto, ze se korenovy filesystem automaticky premountoval jako read-only po zaznamenani chyb.
Děkuji,
máte pravdu, opravdu je vadný druhý disk v raidu sdb2

Takže to bychom měli proč, nyní jsem tedy "rozbil" raid a zkontroloval jestli opravdu :)

vytvořil zálohy pomocí nakopírování mount do root jak říkáte, děkuji,
disky, tedy teď již jen sda2, je RW, do adresáře /bin můžu zapisovat/mazat, ale stále mě trápí ty nesmyslné práva, délky u výše zmiňovaných souborů a stále nevím jak se jich zbavit. Smazat stále nejdou, znovu zkouším mazat podle i-node. Potřeboval bych se jich zbavit před opravou raid, abych nekopíroval vadné soubory.
