Na minulom t\u00fd\u017edni sa konala virtu\u00e1lna konferencia \u201eOpen Source Summit and Embedded Linux<\/a><\/noindex>\u201c Linus Torvalds
\nprediskutoval<\/a><\/noindex> o s\u00fa\u010dasnosti a bud\u00facnosti jadra Linux vo svojej \u00favodnej predn\u00e1\u0161ke s Dirkem Hohndelom zo spolo\u010dnosti VMware. Po\u010das diskusie bola na\u010dat\u00e1 t\u00e9ma gener\u00e1ci\u00ed v prostred\u00ed v\u00fdvoj\u00e1rov. Linus pouk\u00e1zal na to, \u017ee napriek takmer 30-ro\u010dnej hist\u00f3rii projektu, je komunita celkovo dos\u0165 mlad\u00e1 \u2014 medzi v\u00fdvoj\u00e1rmi je ve\u013ea nov\u00fdch \u013eud\u00ed, ktor\u00ed e\u0161te nemaj\u00fa ani 50 rokov. Star\u0161\u00ed \u010dlenovia komunity naozaj star\u0161ej\u00fa a \u0161edivej\u00fa, ale t\u00ed, ktor\u00ed s\u00fa do projektu dlh\u0161ie zapojen\u00ed, sa zvy\u010dajne posunuli od p\u00edsania nov\u00e9ho k\u00f3du k \u00faloh\u00e1m s\u00favisiacim s \u00fadr\u017ebou alebo mana\u017ementom.<\/p>\n

H\u013eadanie nov\u00fdch maintainerov sa pova\u017euje za ve\u013ek\u00fd probl\u00e9m. V komunite je mnoho akt\u00edvnych v\u00fdvoj\u00e1rov, ktor\u00ed s\u00fa radi, \u017ee m\u00f4\u017eu p\u00edsa\u0165 nov\u00fd k\u00f3d, ale m\u00e1lo z nich je ochotn\u00fdch venova\u0165 svoj \u010das na \u00fadr\u017ebu a kontrolu cudz\u00edch k\u00f3dov.
\nOkrem profesionality musia by\u0165 maintaineri ve\u013emi d\u00f4veryhodn\u00ed. Od maintainerov sa tie\u017e vy\u017eaduje neust\u00e1la anga\u017eovanos\u0165 v procese a kontinu\u00e1lna pr\u00e1ca \u2014 \u00fadr\u017eb\u00e1r mus\u00ed by\u0165 v\u017edy dostupn\u00fd, ka\u017ed\u00fd de\u0148 \u010d\u00edta\u0165 e-maily a reagova\u0165 na ne. Pr\u00e1ca v tak\u00fdchto podmienkach vy\u017eaduje vysok\u00fa sebadiscipl\u00ednu, a preto je m\u00e1lo maintainerov a ch\u00fdbaj\u00fa, a h\u013eadanie nov\u00fdch maintainerov, ktor\u00ed s\u00fa schopn\u00ed recenzova\u0165 cudz\u00ed k\u00f3d a navrhova\u0165 zmeny vy\u0161\u0161\u00edm maintainerom, sa st\u00e1va jedn\u00fdm z hlavn\u00fdch probl\u00e9mov v komunite.<\/p>\n

Na ot\u00e1zku \u043e experimentoch v jadre Linus vyjadril n\u00e1zor, \u017ee komunita v\u00fdvoj\u00e1rov jadra si u\u017e nem\u00f4\u017ee dovoli\u0165 niektor\u00e9 bl\u00e1zniv\u00e9 zmeny, ktor\u00e9 sa robili sk\u00f4r. K\u00fdm predt\u00fdm v\u00fdvoj nebol nikomu z\u00e1v\u00e4zn\u00fd, teraz z\u00e1vis\u00ed od jadra Linuxu pr\u00edli\u0161 mnoho syst\u00e9mov.<\/p>\n

Na ot\u00e1zku o prepisovan\u00ed jadra v jazykoch ako Go a Rust, vzh\u013eadom na riziko, \u017ee v 2030-tych rokoch sa v\u00fdvoj\u00e1ri C jazyka m\u00f4\u017eu premeni\u0165 na podobnos\u0165 v\u00fdvoj\u00e1rov v COBOL-u, Linus odpovedal, \u017ee jazyk C zost\u00e1va v prvej desiatke popul\u00e1rnych jazykov, ale pre menej v\u00fdznamn\u00e9 subsyst\u00e9my, ako s\u00fa ovl\u00e1da\u010de zariaden\u00ed, sa zva\u017euje mo\u017enos\u0165<\/a><\/noindex> poskytnutie v\u00e4zieb pre v\u00fdvoj v jazykoch ako Rust. V bud\u00facnosti sa o\u010dak\u00e1va poskytnutie r\u00f4znych modelov p\u00edsania tak\u00fdchto sekund\u00e1rnych komponentov, ktor\u00e9 nie s\u00fa obmedzen\u00e9 na pou\u017e\u00edvanie jazyka C.<\/p>\n

\u00damysel<\/a><\/noindex> spolo\u010dnosti Apple pou\u017e\u00edva\u0165 procesory architekt\u00fary ARM v desktopov\u00fdch a prenosn\u00fdch po\u010d\u00edta\u010doch Linus komentoval s n\u00e1dejou, \u017ee tento krok pom\u00f4\u017ee spr\u00edstupni\u0165 ARM pre pracovn\u00e9 stanice. Posledn\u00fdch 10 rokov Linus s\u0165a\u017eoval na nemo\u017enos\u0165 n\u00e1js\u0165 ARM syst\u00e9m, ktor\u00fd by bol vhodn\u00fd pre v\u00fdvoj\u00e1rske prostredie. Podobne ako pou\u017eitie ARM spolo\u010dnos\u0165ou Amazon, ktor\u00e9 umo\u017enilo posun\u00fa\u0165 t\u00fato architekt\u00faru v serverov\u00fdch syst\u00e9moch, nie je vyl\u00fa\u010den\u00e9, \u017ee v\u010faka krokom Apple sa za nieko\u013eko rokov stan\u00fa dostupn\u00e9 aj v\u00fdkonn\u00e9 PC na ARM, ktor\u00e9 sa bud\u00fa da\u0165 pou\u017ei\u0165 na v\u00fdvoj. Pokia\u013e ide o jeho nov\u00fd PC<\/a><\/noindex> na b\u00e1ze procesora AMD, Linus spomenul, \u017ee v\u0161etko funguje norm\u00e1lne, ak neberieme do \u00favahy ve\u013emi hlu\u010dn\u00fd chladi\u010d.<\/p>\n

O pr\u00e1ci na jadre Linus povedal, \u017ee je to s\u00fa\u010dasne nudn\u00e9 a zauj\u00edmav\u00e9. Nudn\u00e9, preto\u017ee sa mus\u00ed zaobera\u0165 rutinou opr\u00e1v ch\u00fdb a \u00fapravou k\u00f3du, a zauj\u00edmav\u00e9, preto\u017ee neust\u00e1le treba sk\u00fama\u0165 nov\u00e9 technol\u00f3gie, interagova\u0165 s hardv\u00e9rom na n\u00edzkej \u00farovni a kontrolova\u0165 v\u0161etko, \u010do sa deje.<\/p>\n

O COVID-19 Linus spomenul, \u017ee pand\u00e9mia a izol\u00e1cie nemali vplyv na v\u00fdvoj, preto\u017ee procesy interakcie s\u00fa zalo\u017een\u00e9 na komunik\u00e1cii cez e-mail a dia\u013ekovom v\u00fdvoji. Z v\u00fdvoj\u00e1rov jadra, s ktor\u00fdmi Linus spolupracuje, sa nikto infekciou nezranil. Znepokojenie vyvolalo zmiznutie jedn\u00e9ho z spolupracovn\u00edkov na mesiac alebo dva, no to s\u00faviselo s objaven\u00edm tunelov\u00e9ho syndr\u00f3mu.<\/p>\n

Linus tie\u017e spomenul, \u017ee pri v\u00fdvoji jadra 5.8 bude musie\u0165 str\u00e1vi\u0165 viac \u010dasu pr\u00edpravou vydania a vyda\u0165 jeden alebo dva dodato\u010dn\u00e9 testovacie vydania, preto\u017ee toto jadro sa uk\u00e1zalo by\u0165 neoby\u010dajne rozsiahlym<\/a><\/noindex> po\u010det zmien. Ale celkovo pr\u00e1ca na 5.8 zatia\u013e prebieha pomerne hladko.<\/p>\n

V inom rozhovore Linus povedal<\/a><\/noindex>, \u017ee sa u\u017e nepova\u017euje za program\u00e1tora a prestal p\u00edsa\u0165 nov\u00fd k\u00f3d, preto\u017ee u\u017e dlho p\u00ed\u0161e k\u00f3d len v po\u0161tovom klientovi. V\u0161etok svoj \u010das tr\u00e1vi \u010d\u00edtan\u00edm e-mailov a p\u00edsan\u00edm spr\u00e1v. Jeho pr\u00e1ca spo\u010d\u00edva v recenzovan\u00ed zasielan\u00fdch prostredn\u00edctvom e-mailov\u00fdch rozdistrib\u00faci\u00ed patchov a pull-requestov, ako aj v \u00fa\u010dasti na diskusi\u00e1ch o navrhovan\u00fdch zmen\u00e1ch. Ob\u010das vysvet\u013euje svoje n\u00e1pady pomocou pseudok\u00f3du alebo navrhuje \u00fapravy patchov, ktor\u00e9 odosiela v odpovedi bez kompil\u00e1cie a testovania, pri\u010dom pr\u00e1cu na dotiahnut\u00ed na po\u017eadovan\u00fa \u00farove\u0148 zanech\u00e1va p\u00f4vodn\u00e9mu autorovi patchu.<\/p>\n
