N\u00eb list\u00ebn e d\u00ebrguesve t\u00eb zhvilluesve t\u00eb b\u00ebrtham\u00ebs Linux jan\u00eb publikuar patch-e me implementimin e arkitektur\u00ebs \u00abWasm\u00bb p\u00ebr b\u00ebrtham\u00ebn Linux, duke lejuar kompilimin e b\u00ebrtham\u00ebs n\u00eb kodin nd\u00ebrmjet\u00ebs WebAssembly p\u00ebr ekzekutimin e drejtp\u00ebrdrejt\u00eb n\u00eb shfletuesin web pa p\u00ebrdorur emulatore.

Si fillim, \u00ebsht\u00eb krijuar nj\u00eb ambient i bazuar n\u00eb nj\u00eb grup utilitar\u00ebsh t\u00eb kompiluar n\u00eb WebAssembly, BusyBox dhe bibliotek\u00ebn sistemike musl.

Projekti ka qen\u00eb n\u00eb zhvillim p\u00ebr rreth dy vjet dhe n\u00eb faz\u00ebn aktuale lejon ngarkimin e b\u00ebrtham\u00ebs n\u00eb shfletues dhe ekzekutimin e programeve standarde.

P\u00ebr shembull, mb\u00ebshtetje p\u00ebr thirrjet vfork dhe longjmp nuk \u00ebsht\u00eb ende zbatuar (patch-e jan\u00eb aplikuar n\u00eb BusyBox p\u00ebr t\u00eb punuar pa to), mungon mund\u00ebsia p\u00ebr ta p\u00ebrfunduar detyrat, MMU nuk \u00ebsht\u00eb i disponuesh\u00ebm (b\u00ebrthama dhe proceset punojn\u00eb n\u00eb t\u00eb nj\u00ebjtin hap\u00ebsir\u00eb adresash), nuk \u00ebsht\u00eb e mundshme t\u00eb ndryshohet kodi q\u00eb \u00ebsht\u00eb ngarkuar tashm\u00eb, dhe konsola has n\u00eb ngecje pas rreth 5 minutash p\u00ebr shkak t\u00eb problemeve me ndarjen e koh\u00ebs. K\u00ebto kufizime jan\u00eb t\u00eb tejkalueshme, por p\u00ebr disa prej tyre k\u00ebrkohet zbatimi i zgjerimeve t\u00eb tjera n\u00eb shfletues p\u00ebr WebAssembly.

Fusha e aplikimit t\u00eb projektit shkon p\u00ebrtej thjesht nxjerrjes s\u00eb ambient\u00ebve Linux n\u00eb k\u00ebrkues.

Porti gjithashtu do t\u00eb jet\u00eb i dobish\u00ebm p\u00ebr organizimin e ekzekutimit t\u00eb izoluar t\u00eb aplikacioneve p\u00ebrmes WASI (WebAssembly System Interface). <\/p>\n
