Github publikoval Octoverse 2025 (YouTube), tj. každoroční přehled o stavu open source a veřejných softwarových projektů na GitHubu. Každou sekundu se připojil více než jeden nový vývojář. Nejpoužívanějším programovacím jazykem se stal TypeScript.
Kit je nový maskot webového prohlížeče Firefox.
Mastodon (Wikipedie) - sociální síť, která není na prodej - byl vydán ve verzi 4.5. Přehled novinek s náhledy v oznámení na blogu.
Německo zvažuje, že zaplatí místním telekomunikačním operátorům včetně Deutsche Telekom, aby nahradili zařízení od čínské firmy Huawei. Náklady na výměnu by mohly přesáhnout dvě miliardy eur (bezmála 49 miliard Kč). Jeden scénář počítá s tím, že vláda na tento záměr použije prostředky určené na obranu či infrastrukturu.
Po dvaceti letech skončil leader japonské SUMO (SUpport.MOzilla.org) komunity Marsf. Důvodem bylo nasazení sumobota, který nedodržuje nastavené postupy a hrubě zasahuje do překladů i archivů. Marsf zároveň zakázal použití svých příspěvků a dat k učení sumobota a AI a požádal o vyřazení svých dat ze všech učebních dat.
Úřad pro ochranu hospodářské soutěže zahajuje sektorové šetření v oblasti mobilních telekomunikačních služeb poskytovaných domácnostem v České republice. Z poznatků získaných na základě prvotní analýzy provedené ve spolupráci s Českým telekomunikačním úřadem (ČTÚ) ÚOHS zjistil, že vzájemné vztahy mezi operátory je zapotřebí detailněji prověřit kvůli možné nefunkčnosti některých aspektů konkurence na trzích, na nichž roste tržní podíl klíčových hráčů a naopak klesá význam nezávislých virtuálních operátorů.
Různé audity bezpečnostních systémů pařížského muzea Louvre odhalily závažné problémy v oblasti kybernetické bezpečnosti a tyto problémy přetrvávaly déle než deset let. Jeden z těchto auditů, který v roce 2014 provedla francouzská národní agentura pro kybernetickou bezpečnost, například ukázal, že heslo do kamerového systému muzea bylo „Louvre“. 😀
Z upstreamu GNOME Mutter byl zcela odstraněn backend X11. GNOME 50 tedy poběží už pouze nad Waylandem. Aplikace pro X11 budou využívat XWayland.
Byl publikován plán na odstranění XSLT z webových prohlížečů Chrome a Chromium. S odstraněním XSLT souhlasí také vývojáři Firefoxu a WebKit. Důvodem jsou bezpečnostní rizika a klesající využití v moderním webovém vývoji.
Desktopové prostředí LXQt (Lightweight Qt Desktop Environment, Wikipedie) vzniklé sloučením projektů Razor-qt a LXDE bylo vydáno ve verzi 2.3.0. Přehled novinek v poznámkách k vydání.

Teď jsem trochu zmatený, jestli ten disk opravdu umřel nebo ne, protože když si vypíšu aktivní disky připojené v systému:
root@server:~# mdadm --query --examine /dev/sda /dev/sda: MBR Magic : aa55 Partition[0] : 61440 sectors at 2048 (type 82) Partition[1] : 1953460224 sectors at 63488 (type fd) root@server:~# mdadm --query --examine /dev/sdb /dev/sdb: MBR Magic : aa55 Partition[0] : 61440 sectors at 2048 (type 82) Partition[1] : 1953460224 sectors at 63488 (type fd)...tak se zdá že oba disky jsou v pořádku. Mohl bych se zeptat, jestli by mi někdo poradil nebo spíš vysvětlil co se stalo, popřípadě nenavedl jak vrátit oba disky do pole md0? Předem moc děkuji :)

Myslím, že oba dva disky vypadají v pořádku pokud se nepletu, žádné chybové hlášky v Error Log.
smartctl -t short /dev/sdbnebo
smartctl -t long /dev/sdbA ž test proběhne, vypíšeš si to znovu (průběh testu možná uvidíš ve výpisu, ale možná taky ne, nebo ti nepůjde výpis v průběhu testu udělat - je to dle daného disku).
mdadm /dev/md0 --add /dev/sdb2V tom /proc/mdstat uvidíš, co to udělalo. Máš aktuální /etc/mdadm/mdadm.conf a následně přegenerovaný initramfs, aby se do něj dostal ten aktuální mdadm.conf?

Takže vypadá to, že se zadařilo. Ale absolutně nechápu proč se tomu tak stalo, že se jeden disk odpojil a vypadl z pole. Dalo by se to nějak zpětně zjistit? ještě že jsem si toho všiml, občas tu kontrolu udělám - proto mě to zarazilo že je v poli defacto jen jeden disk. V každém případě bych chtěl poděkovat všem zainteresovaným za pomoc.
Dalo by se to nějak zpětně zjistit?Kernel nejspíš vypíše něco jako „media error“, „timeout“ nebo něco jiného. grepni syslog, messages a další (podle distribuce a nastavení rsyslogu) na název toho disku.
ještě že jsem si toho všiml, občas tu kontrolu udělámJá dávám do cronu grep na "_" v /proc/mdstat s tím, že mi přijde e-mail, když tam je
mdadm --detail --scan >> /etc/mdadm.conf a pak v editoru vyhodis stary radky
ze smartu je videt, ze disky jsou ok, ale zatim jsi nikdy jest nepoustel ani jeden smart test, tedy treba jendou mesicne je dobre udelat smartctl -t long /dev/sda, kontrola vysledku pomoci smartctl -a /dev/sda
no a pole se muze kontrolovat treba jednou tydne pomoci echo check >> /sys/block/md0/md/sync_action, az to dobehne, tak kouknes do cat /sys/block/md?/md/mismatch_cnt a mely by tam byt nuly
nejlip si obe kontroly dej do cronu
mdadm --detail --scan >> /etc/mdadm.conf konfigu se UUID shodovaly s tím původně vytvořeným.
Když se všechna data opět sesypala dohromady tak jsem stroj ještě jednou přezkoušel, restartoval a všechno najelo v pořádku - takže skvělá práce a mnohé díky za pomoc. Pro kontrolu přidávám aktuální stav pole:
