V Tchaj-peji probíhá počítačový veletrh COMPUTEX 2023. Firmy představují své novinky. Nvidia například superpočítač DGX GH200 AI.
Vyšla nová verze XMPP (Jabber) klienta Gajim. Nejvýznamnější novinkou je integrace OMEMO pluginu přímo do jádra aplikace, takže již není třeba plugin samostatně instalovat. Přehled dalších novinek je dostupný na oficiálních stránkách. Gajim je vytvořen v jazyce Python s využitím knihovny GTK a vedle Linuxu jej lze vyzkoušet i na platformách MacOS a Windows.
Komunita KDE představila stránku KDE for Developers pro vývojáře používající KDE aplikace. Postupně byly představeny stránky pro umělce KDE for Creators, děti KDE for Kids a vědce KDE for Scientists.
Společnost ARM představila platformu Total Compute Solutions 2023 (TCS23) s 5. generací GPU Immortalis-G720, Mali-G720 a Mali-G620 a Armv9.2 CPU Cortex-X4, Cortex-A720 a Cortex-A520 s DSU-120.
Na konferenci Microsoft Build 2023 byl představen Azure Linux container host for Azure Kubernetes Service (AKS). Podrobnosti ve videu s otázkami a odpovědmi. Shrnutí v článku na DevClass.
Na itch.io probíhá Linux Game Jam 2023. Zapojit se a přihlásit hru běžící na Linuxu lze do 6. června do 01:59. Zahrát si lze hry z loňského ročníku.
Na Steamu lze získat zdarma počítačové hry Warhammer 40,000: Gladius - Relics of War a Hue. Na Epic Games Storu počítačovou hru Fallout: New Vegas - Ultimate Edition.
WordPress (Wikipedie), open source systém pro správu webového obsahu (CMS), zítra slaví 20 let. První verze byla vydána 27. května 2003.
Deno (Wikipedie), běhové prostředí (runtime) pro JavaScript, TypeScript a WebAssembly, bylo vydáno ve verzi 1.34. Přehled novinek v poznámkách k vydání. Od verze 1.6 lze pomocí "deno compile" sestavit ze zdrojových kódů binární spustitelný soubor. Nově "deno compile" podporuje také npm balíčky.
Aktuálně posledním 14. open source filmem od Blender Studia je CHARGE (YouTube). Dokončuje se 15. film Pet Projects. Začíná se pracovat na 16. filmu s pracovním názvem Project Gold.
Zapomněl jsem doma křišťálovou kouli.
Chtělo by to najít konkrétní stránku, která se načítá pomalu, a zavolat na to například strace wget. Pak se dá podle timestampů v tom logu zjistit, kde by mohl být problém (tedy kde je podezřelá mezera).
Hlavní je zjistit, jestli je problém v DNS resolvingu (primární DNS nebo jeden z nastavených DNS je nedostupný — častý problém, který se projevuje zdánlivě náhodně) nebo před DNS resolvingem (nějaký zapomenutý nesmysl v /etc/hosts a klasické nastavení hosts bind v /etc/nsswitch.conf) nebo až po DNS resolvingu, tedy během TCP spojení (problém s routingem, problém s (malou) MTU, chybně nastavený IPv6 (například se špatnými preferovanými adresami, které se nedají routovat) končící fallbackem na IPv4) a tak dále.
Ubuntu občas mívá ve (zlo)zvyku zapínat dnsmasq, je-li nainstalovaný (což ostatně dělá u spousty dalších balíčků). Je-li tam dnsmasq, je rozumně funkční? Co říká dig na nějakou tu hledanou doménu a za jak dlouho? (Co potom říká ping na IPv6 a IPv4 adresy toho serveru, jen tak pro jistotu?) Je-li problém v DNS, pomůže odinstalování dnsmasq? Co říká getaddrinfo z balíku libsocket-getaddrinfo-perl na adresu hledané domény? Jsou první adresy ve vráceném seznamu pingnutelné?
Opravdu je Internet pomalý? Co na to iperf? Je opravdu nějaký problém v throughputu, nebo je jenom někde schovaná obrovská latence u jednoho dílčího kroku?
Zaprvé, bez <pre> by to fakt nešlo.
Zadruhé, vidím tam nastavenou IPv4 i IPv6 adresu, takže adresy routeru by se daly najít například ve výstupu z ip -4 route show a ip -6 route show na řádce, která má v sobě default. (Samozřejmě půjde o neveřejnou IPv4 adresu a s největší pravděpodobností o link-local IPv6 adresu, nikoliv o vnější/veřejné adresy routeru. Ale to nevadí — ping se přes ně vyzkoušet dá. Co se loginu týká, tam záleží na tom, co je to za router. Předřečník, který navrhoval login na router, měl asi na mysli otázku, zda funguje webové rozhraní routeru (to, kterým se konfiguruje WiFi a ethernet) a zda se to webové rozhraní routeru taky načítá pomalu nebo s prodlevou.
Dá-li se dostat na webové rozhraní routeru, pak je pro diagnostiku IPv4 i IPv6 použitelná přímo v prohlížeči normálně IP adresa routeru, tedy například (teď střílím úplně náhodně od boku; nutno zjistit z ip route show) http://10.0.0.1/ nebo http://[2a00:1028:96d6:edea::]/ Tak se dá zvlášť pro IPv4 a IPv6 vyzkoušet, zda to alespoň lokálně funguje podle očekávání.
Zatřetí, možná by to chtělo vypnout privacy extensions, jen tak pro jistotu. Vidím tam 2 IPv6 adresy, což bývá právě kvůli privacy extensions. Někdy (byť velmi vzácně) je špatné nastavení privacy extensions příčinou nespolehlivých spojení, zejména v kombinaci s některými rádoby-chytrými firewally, které se snaží blokovat spojení z „neprivátních“ adres, a se špatně fungujícím NetworkManagerem, který nedává adresám správné priority pro address selection. Všechno je to krajně nepravděpodobné, ale čistě pro redukci počtu možných příčin problému doporučuji privacy extensions vypnout.

Ne, nešla by bez strace. V strace je klíčový hint, kde se to zdržuje.

znamená, že v resolv.conf má jako rekurzivní resolver localhost nebo ne?
No, to tak má Ubuntu. V jiných distrech to nikdy nemívám, protože mi to připadá jako další point of failure navíc. Nejsem si ovšem jistý, jestli dnsmasq musí nutně být plný resolver — asi záleží na tom, jak je nastavený. Může třeba dělat jenom cache a rekurzivní dotazy přeposílat nějakým dalším DNS serverům, místo aby to bral z gruntu od root-servers.net.
Jo, tady je to stejné. Resolvne se to hned, ale pak je tam obrovská prodleva. Takže tam bude mimo jiné i problém na straně (tohoto konkrétního) serveru.
V tom strace jsou vidět asi tak 4 pokusy o DNS resolving pomocí serveru 127.0.1.1 (tedy pomocí adresy, na které obvykle poslouchá místní dnsmasq), každý z nich s timeoutem 5 sekund. Takže buď byl tazatelův počítač zrovna náhodou během spuštění wgetu odpojený, nebo se dnsmasq z nějakého důvodu nedokáže vůbec domluvit s externími DNS servery.
Taky je možné, že prohlížeč, který má v 99% případů vlastní fallback při resolvingu a nespoléhá vždy jen na /etc/nsswitch.conf a /etc/resolv.conf, se nakonec k serveru připojí, zatímco wget při striktním respektování konfigurace nikoliv. Hlášky z strace tady končí neúspěchem.

Tohle je ono. Tahle část obsahuje tu mezeru v timestampech, o které jsem mluvil. Několikrát se to snaží něco resolvnout na adrese 127.0.1.1 (kterážto divná pseudo-IPv4-localhost adresa (není to 127.0.0.1) souvisí právě s již jmenovaným dnsmasq) a několikrát se to nepovede (resp. nastane timeout po 5 sekundách), což pokaždé stojí 5 sekund času.

Doporučuji přečíst si tohle a na základě toho zkusit zakázat dnsmasq, čistě na zkoušku, jestli to pomůže. (Aspoň se tím vyloučí další možná příčina problému.)
Samozřejmě předpokládám, že jsi to zkusil (se stejným výsledkem) taky na jiné stránky / domény, nikoliv jen pro tu jedinou uvedenou. 
A jestli je příčina jinde než v dnsmasq (což je pravděpodobné, protože na spoustě systémů dnsmasq prostě tiše funguje a nic zlého nedělá), pak by bylo přínosné podívat se do logů od dnsmasq, jestli říká něco o tom, proč nemůže resolvovat. Nějaký vnější problém s DNS se ale dá odhalit stejně dobře i bez dnsmasq, například několika příkazy dig.
Jak jsou nastavené DNS servery? Jsou DNS servery, které vrací router přes DHCPv6, DHCPv4 a RADV všechny funkční? Jsou někde v NetworkManagerovi nastavené manuálně ještě jiné DNS servery? Není někde zapomenutý nefunkční DNS server nebo DNS server od jiného/předchozího operátora, který například zahazuje rekurzivní dotazy (ne-li všechny dotazy) ze současné IP adresy? Jak už jsem někde psal — chtělo by to zjistit seznam DNS serverů, se kterými systém pracuje, a každý z nich prověřit pomocí ping/ping6 a dig.
Vždyť je v tom výstupu nakonec i jasně vidět: wget: chybí URL
Ten wget bere jako první parametr URL nějaké webové stránky. Tenhle pokus, který jenom ohlásil chybu a okamžitě skončil, nic zajímavého netestuje. Proto jsem psal, že je třeba tím wgetem zkusit stáhnout některou z těch stránek, které se pomalu načítají.
Mně to začíná připadat jako problém s IPv6 routingem. Hypotéza: Co když se naváže IPv4 spojení přes DHCP, pár sekund pak vše normálně funguje, ale zanedlouho (například každých 15 sekund, tedy za 7,5 sekundy v průměru) přijde router advertisement, který nakonfiguruje IPv6 — a žuch. Pokud je hypotéza správná, prohlížeč by zkusil napřed IPv6, což by nešlo, a pak by následoval fallback na IPv4.
Zjevně tam máš veřejnou IPv6 adresu, takže bych zkusil pingnout nějaký server přes IPv4 i IPv6, aby bylo vidět, jak to chodí a jestli tam není nějaká ultra prodleva. Na některých distrech se to jmenuje ping pro IPv4 a ping6 pro IPv6, na jiných distrech je to ping -4 a ping -6. (Chce to zvolit server, který má IPv4 i IPv6 adresy, což se dá ověřit pomocí dig doména AAAA a dig doména A, případně pomocí getaddrinfo (z balíku perl-socket-getaddrinfo.))
Otázkou taky je, proč to tomu desktopu funguje, zatímco notebooku ne. Je na notebooku nějaký firewall? Co říkají „pod rootem“ (tedy přes sudo) příkazy iptables-save a ip6tables-save? Dá se firewall vypnout? Co třeba odinstalováním balíku ufw? Možná je ve firewallu nějaký podivný zákaz.
Zpět k původním dotazům: Běží tam dnsmasq? Je něco neobvyklého v /etc/dnsmasq.d (něco po manuální změně nebo tak)? Jaký je obsah souboru /etc/resov.conf a /etc/nsswitch.conf? Dají se normálně resolvovat domény?
Sorry, překlep, /etc/resolv.conf.
To je ale škoda, protože tím se úplně zbytečně omezí i MTU v domácí síti, nejen směrem ven. Problém s DSL a MTU obvykle nastává kvůli kombinaci DSL a špatného nastavení firewallu, který nepropouští některé důležité ICMP pakety. Samotné DSL tohle nezpůsobuje.
