Yocto Vs. Ubuntu: Qhov Linux Distribution Twg Zoo Tshaj Plaws Rau Embedded Systems, Iot, Thiab Edge Computing?

Hauv ntiaj teb ntawm kev tsim kho Linux uas tau teeb tsa, kev xaiv lub operating system zoo qee zaum yog thawj qhov kev txiav txim siab - thiab tseem ceeb tshaj plaws -. Yocto Project thiab Ubuntu yog ob qho kev daws teeb meem nrov tshaj plaws. Txawm hais tias ob qho tib si yog raws li Linux, lawv cov kev xav tsim qauv thiab cov ntaub ntawv siv sib txawv heev. Cov kws ua haujlwm, cov neeg tsim khoom, thiab cov neeg txiav txim siab ua haujlwm ntawm cov kab ke embedded, IoT gateways, industrial PCs, thiab cov khoom siv edge computing yuav tsum nkag siab txog qhov sib txawv no.

Nyob rau theem siab:

• Ubuntu yog ib qho Linux faib tawm dav dav uas tau los ntawm Debian, paub txog nws qhov yooj yim siv, kev tswj hwm pob khoom dav dav (APT), thiab kev txhawb nqa hauv zej zog. Nws feem ntau nyiam rau kev tsim qauv sai, kev sim, thiab kev tsim kho ib puag ncig.
• 
  Qhov project Yocto, ntawm qhov tod tes, tsis yog kev faib tawm tab sis yog kev faib tawm meta - ib qho kev tsim kho uas yooj ywm uas tso cai rau cov neeg tsim khoom los tsim cov duab Linux tshwj xeeb uas tsim rau cov khoom siv kho vajtse, kev ua tau zoo, thiab qhov yuav tsum tau ua.
• Qhov kev sib txawv no yog qhov tseem ceeb vim tias qhov xav tau ntawm cov khoom siv uas muaj kev txwv tsis pub siv ntau yam sib txawv ntawm cov chaw ua haujlwm lossis server. Yocto raug soj ntsuam txawv los ntawm cov neeg tsim khoom ua haujlwm ntawm cov firmware tsim khoom, qhov chaw tsawg kawg nkaus, lossis kev saib xyuas mus sij hawm ntev dua li cov neeg tsim khoom uas muab qhov tseem ceeb rau kev tsim qauv sai, kev sib raug zoo ntawm software, thiab kev yooj yim siv nrog Ubuntu.
• Thaum kawg, qhov kev sib piv ntawm Yocto thiab Ubuntu yog los nrhiav qhov sib npaug ntawm kev ywj pheej, kev ua haujlwm zoo, thiab kev txhim kho sai. Yog li ntawd, qhov no yog qhov tseem ceeb rau txhua tus neeg uas txhawj xeeb txog yav tom ntej ntawm embedded Linux systems.

Ubuntu yog ib qho kev faib tawm Linux raws li Debian uas Canonical tswj hwm, muaj nyob rau hauv desktop, server, thiab Ubuntu Core variants. Nws paub dav rau nws cov hauv qab no:

• yooj yim siv thiab teeb tsa sai
• Kev tswj hwm pob khoom APT rau kev teeb tsa software yooj yim
• Cov kev txhawb nqa ntev (LTS) lav qhov ruaj khov rau tsib xyoos lossis ntev dua.
• Kev txhawb nqa thiab cov ntaub ntawv hauv zej zog ntau heev

Rau cov neeg tsim khoom, Ubuntu yog qhov kev xaiv ntuj thaum kev tsim qauv sai, kev sib raug zoo ntawm daim ntawv thov dav dav, thiab kev siv tau yooj yim yog qhov tseem ceeb tshaj plaws. Nws feem ntau raug xa mus rau hauv cov servers, IoT cov khoom siv, thiab cov txheej txheem suav ntug uas kev hloov kho kev ruaj ntseg thiab kev tswj hwm cov kev pabcuam los ntawm Canonical ua lub luag haujlwm tseem ceeb.

Qhov sib txawv, Yocto project tsis yog kev faib tawm, tab sis yog kev faib tawm meta - Ib lub moj khaum siv los tsim cov duab Linux kev cai. Hloov chaw xa cov operating system uas tau teev tseg ua ntej, Yocto tso cai rau cov neeg tsim khoom kom:

• Kho cov duab ntawm lub system kom ua tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom siv kho vajtse
• Txo qhov chaw thiab kev siv cov peev txheej rau cov khoom siv tsawg
• Siv cov zaub mov txawv BitBake thiab OpenEmbedded core los tswj txhua yam khoom
