Dmitrij Brant z organiz\u00e1cie Wikimedia predstavil port ovl\u00e1da\u010da ftape pre modern\u00e9 Linuxov\u00e9 jadr\u00e1. Ovl\u00e1da\u010d prestal by\u0165 aktualizovan\u00fd v roku 2000 a bol vyl\u00fa\u010den\u00fd z jadra 2.6.20 v roku 2006 kv\u00f4li probl\u00e9mom pri pr\u00e1ci na viacjadrov\u00fdch syst\u00e9moch. Na obnovenie schopnosti kompil\u00e1cie a fungovania ovl\u00e1da\u010da v distrib\u00faci\u00e1ch s modern\u00fdmi Linuxov\u00fdmi jadrami bolo potrebn\u00e9 jeho prepracovanie s oh\u013eadom na zmeny vn\u00fatorn\u00fdch API a subsyst\u00e9mov jadra, ktor\u00e9 sa udiali za posledn\u00fdch 20 rokov. <\/p>\n

Portovanie je pozoruhodn\u00e9 t\u00fdm, \u017ee bolo vykonan\u00e9 takmer v\u00fdhradne s pomocou AI asistenta Claude Code. Nakoniec bol vytvoren\u00fd plne funk\u010dn\u00fd ovl\u00e1da\u010d, schopn\u00fd sa kompilova\u0165 a fungova\u0165 na syst\u00e9moch s jadrami 6.8 a nov\u0161\u00edmi. Portovanie prebiehalo v troch f\u00e1zach. V prvej f\u00e1ze bola AI asistentovi dan\u00e1 \u00faloha modifik\u00e1cie k\u00f3du ovl\u00e1da\u010da, ktor\u00fd mohol by\u0165 kompilovan\u00fd iba s jadrami 2.4, pre zostavenie s nov\u00fdmi verziami jadra. AI \u00faspe\u0161ne nahradil v ovl\u00e1da\u010di volania na zastaran\u00e9 funkcie jadra aktu\u00e1lnymi volaniami, upravil pou\u017e\u00edvanie d\u00e1tov\u00fdch \u0161trukt\u00far a odstr\u00e1nil v\u0161etky chyby vznikaj\u00face pri zostaven\u00ed. <\/p>\n

V druhej f\u00e1ze bola stanoven\u00e1 \u00faloha previes\u0165 ovl\u00e1da\u010d z kompilovate\u013enej formy v jadre na variant, schopn\u00fd pracova\u0165 ako na\u010d\u00edtate\u013en\u00fd modul jadra. AI asistent pripravil na\u010d\u00edtate\u013en\u00fd modul. V tretej f\u00e1ze, prostredn\u00edctvom poskytnutia AI asistentovi dmesg v\u00fdstupu s inform\u00e1ciami o chyb\u00e1ch a probl\u00e9moch, ktor\u00e9 vznikli po\u010das prev\u00e1dzky, ako aj referen\u010dn\u00fdch laden\u00fdch dmesg spr\u00e1v od funguj\u00faceho star\u00e9ho ovl\u00e1da\u010da, bol port uveden\u00fd do prev\u00e1dzkov\u00e9ho stavu, schopn\u00e9ho identifikova\u0165 pr\u00edtomnos\u0165 p\u00e1skov\u00e9ho \u00falo\u017eiska a extrahova\u0165 obsah kaziet. <\/p>\n

Pr\u00e1ca, ktor\u00e1 sa na za\u010diatku zdala by\u0165 zdolate\u013en\u00e1 a vy\u017eadovala nieko\u013eko t\u00fd\u017ed\u0148ov \u0161t\u00fadia dokument\u00e1cie, sa podarilo vykona\u0165 za dva ve\u010dery. Na vytvorenie pracuj\u00faceho modulu bolo potrebn\u00fdch tri po\u017eiadavky, nieko\u013eko diskusi\u00ed a p\u00e1r manu\u00e1lnych \u00faprav k\u00f3du. Dmitrij z\u00e1rove\u0148 zd\u00f4raz\u0148uje, \u017ee netreba prece\u0148ova\u0165 AI-asistenty, ktor\u00ed s\u00fa len n\u00e1stroje vy\u017eaduj\u00face rozumn\u00fa interakciu. Dmitrij ovl\u00e1da jazyk C a m\u00e1 predstavu o moduloch jadra, ale prin\u00fati\u0165 AI-asistenta p\u00f4sobi\u0165 spr\u00e1vnym smerom bez znalosti vn\u00fatornej \u0161trukt\u00fary modulov jadra by pod\u013ea neho nebolo mo\u017en\u00e9. <\/p>\n

Pri formulovan\u00ed \u00falohy je potrebn\u00e9 pozna\u0165 \u0161pecifik\u00e1 a pou\u017e\u00edva\u0165 profesion\u00e1lnu terminol\u00f3giu, presne formulova\u0165 r\u00e1mec realizovanej funkcie a definova\u0165 pr\u00e1zdne miesta v tomto r\u00e1me, ktor\u00e9 by mal AI vyplni\u0165. Tie\u017e je potrebn\u00e9 presk\u00fama\u0165 siln\u00e9 a slab\u00e9 str\u00e1nky AI-asistentov, aby sme im ned\u00e1vali \u00falohy, s ktor\u00fdmi si nebud\u00fa vedie\u0165 poradi\u0165. Na dosiahnutie v\u00fdsledku Dmitrij rad\u00ed pova\u017eova\u0165 AI-asistenta za zosil\u0148ova\u010d vlastn\u00fdch zru\u010dnost\u00ed a komunik\u00e1ciu s n\u00edm za spolupr\u00e1cu s podriaden\u00fdm in\u017einierom, ktor\u00fd spln\u00ed v\u0161etko, \u010do je povedan\u00e9, sna\u017e\u00ed sa by\u0165 u\u017eito\u010dn\u00fd, je sebavedom\u00fd, ale uzn\u00e1va chyby. Rozhodovanie, stanovenie pravidiel a zodpovednos\u0165 za v\u00fdsledok zost\u00e1va na \u010dloveku. <\/p>\n

Ovl\u00e1da\u010d ftape je ur\u010den\u00fd na pr\u00e1cu s p\u00e1skov\u00fdmi pam\u00e4\u0165ami, ktor\u00e9 pou\u017e\u00edvaj\u00fa kazety QIC, v ktor\u00fdch sa uplat\u0148uje vlastn\u00fd propriet\u00e1rny form\u00e1t k\u00f3dovania a kompresie inform\u00e1ci\u00ed. Tak\u00e9to zariadenia sa \u010dasto pou\u017e\u00edvali v 90. rokoch na z\u00e1lohovanie.

Pri tom pripojenie \u00falo\u017eiska cez ovl\u00e1da\u010d Floppy diskov pripom\u00ednalo hack, preto\u017ee ovl\u00e1da\u010d musel \ufffdoblafn\u00fa\u0165\ufffd ovl\u00e1da\u010d, ur\u010den\u00fd na pr\u00e1cu len s Floppy diskami, aby mohol posiela\u0165 pr\u00edkazy a organizova\u0165 interakciu s p\u00e1skov\u00fdm \u00falo\u017eiskom. <\/p>\n

Predt\u00fdm na extrakciu inform\u00e1ci\u00ed z p\u00e1skov\u00fdch kaziet musel Dmitrij pou\u017e\u00edva\u0165 samostatn\u00fd po\u010d\u00edta\u010d s CentOS 3.5 a jadrom 2.4.21.

Podporuj\u00fa sa 32- a 64-bitov\u00e9 zostavy, ale na pr\u00e1cu s zariadeniami pripojen\u00fdmi k ovl\u00e1da\u010du Floppy-diskov je potrebn\u00e1 z\u00e1kladn\u00e1 doska s tak\u00fdmto ovl\u00e1da\u010dom. <\/p>\n

Medzi oblasti pou\u017eitia ovl\u00e1da\u010da patr\u00ed obnova inform\u00e1ci\u00ed zo star\u00fdch p\u00e1skov\u00fdch kaziet a jeho pou\u017eitie v projektoch na rekre\u00e1ciu retropo\u010d\u00edta\u010dov.
