Thaum npaj peb cov kev kawm, peb ib txwm ntsib teeb meem ntawm kev ua haujlwm nrog qee yam cuab yeej. Thiab tam sim no thaum peb ntsib lawv, tsis tas yuav muaj cov ntaub ntawv txaus thiab cov ntawv uas yuav pab peb daws qhov teeb meem no. Qhov no yog qhov xwm txheej, piv txwv li, hauv 2015, thiab hauv "Cov Ntaub Ntawv Tshwj Xeeb" peb siv [...]
Nyob zoo, Habr! Nyob rau hauv 2017, thaum lub sij hawm Dub Friday, lub load tau nce los ntawm yuav luag ib thiab ib nrab lub sij hawm, thiab peb cov servers nyob ntawm lawv txwv. Xyoo dhau los, tus naj npawb ntawm cov neeg siv khoom tau nce siab, thiab nws tau pom tseeb tias tsis muaj kev npaj ua ntej, lub platform tsuas yog tsis tuaj yeem tiv taus cov khoom ntawm 2018. Peb tau teeb tsa lub hom phiaj xav tau tshaj plaws: peb xav npaj siab [...]
Dab tsi peb yuav qhia koj txog: Yuav ua li cas sai sai xa cov kev sib koom ua ke rau ob lub servers raws li kev daws teeb meem drbd + ocfs2. Qhov no yuav pab tau rau leej twg: Cov lus qhia yuav muaj txiaj ntsig zoo rau cov thawj coj hauv lub cev thiab txhua tus neeg uas xaiv cov txheej txheem khaws cia lossis xav sim cov tshuaj. Peb tau txiav txim siab dab tsi thiab vim li cas?
Taw qhia Hauv tsab xov xwm no kuv yuav tham txog lub npe nrov Huffman algorithm, nrog rau nws daim ntawv thov hauv cov ntaub ntawv compression. Yog li ntawd, peb yuav sau ib qho yooj yim archiver. Muaj twb muaj ib tsab xov xwm hais txog qhov no ntawm Habre, tab sis tsis muaj kev siv tswv yim. Cov ntaub ntawv theoretical ntawm cov ntawv tshaj tawm tam sim no yog muab los ntawm tsev kawm ntawv cov kev kawm computer science thiab Robert Laforet phau ntawv "Data Structures and Algorithms in Java". Yog li, txhua yam [β¦]
Prelude Kab lus no yog hais txog binary nrhiav ntoo. Tsis ntev los no kuv tau sau ib tsab xov xwm hais txog cov ntaub ntawv compression siv txoj kev Huffman. Nyob ntawd kuv tsis tau them nyiaj ntau rau cov ntoo binary, vim tias kev tshawb nrhiav, ntxig, thiab tshem tawm txoj kev tsis cuam tshuam. Tam sim no kuv txiav txim siab sau ib tsab xov xwm txog ntoo. Cia peb pib. Ib tsob ntoo yog cov ntaub ntawv qauv uas muaj cov nodes txuas nrog cov npoo. Peb tuaj yeem hais tias tsob ntoo yog [...]
Hauv ntu kawg, peb tau paub txog Termux cov lus txib yooj yim, teeb tsa SSH kev sib txuas nrog lub PC, kawm paub yuav ua li cas tsim cov npe npe thiab teeb tsa ntau yam khoom siv siv tau zoo. Lub sijhawm no peb yuav tsum mus ntxiv, koj thiab kuv: peb yuav kawm txog Termux: API, nruab Python thiab nano, thiab tseem sau "Nyob zoo, ntiaj teb!" hauv Python peb yuav kawm txog bash scripts thiab sau ib tsab ntawv [β¦]
Nco tseg transl.: Thawj ntu ntawm cov koob no tau mob siab rau kom paub txog lub peev xwm ntawm Istio thiab ua kom pom lawv hauv kev nqis tes ua. Tam sim no peb yuav tham txog ntau txoj hauv kev ntawm kev teeb tsa thiab kev siv cov kev pabcuam mesh no, thiab tshwj xeeb, hais txog kev ua haujlwm zoo thiab kev tswj xyuas tsheb khiav hauv lub network. Peb kuj tseem ceeb rau koj tias tsab xov xwm no siv cov kev teeb tsa (manifests rau Kubernetes thiab Istio) [β¦]
Nco tseg Kev txhais lus: Kev pabcuam meshes tau dhau los ua qhov kev daws teeb meem tseem ceeb hauv cov txheej txheem niaj hnub rau kev siv tom qab microservice architecture. Thaum Istio tuaj yeem nyob ntawm daim di ncauj ntawm ntau tus kws tsim khoom DevOps, nws yog ib yam khoom tshiab uas, thaum ua tiav ntawm cov peev txheej nws muab, yuav xav tau ntau lub sijhawm kom paub txog. German engineer Rinor Maloku, lub luag haujlwm rau huab xam rau cov neeg siv khoom loj hauv kev sib txuas lus [...]
Nco tseg transl.: Thawj ntu ntawm cov yeeb yaj kiab no tau mob siab rau kom paub txog lub peev xwm ntawm Istio thiab ua kom pom lawv hauv kev nqis tes ua, qhov thib ob yog hais txog kev ua haujlwm zoo thiab kev tswj xyuas kev khiav tsheb hauv network. Tam sim no peb yuav tham txog kev ruaj ntseg: txhawm rau ua kom pom cov haujlwm yooj yim ntsig txog nws, tus sau siv Auth0 qhov kev pabcuam tus kheej, tab sis lwm tus neeg muab kev pabcuam tuaj yeem teeb tsa tau zoo ib yam. Peb tau teeb tsa [β¦]
Cov phooj ywg, peb tau los nrog lub zog tshiab. Ntau tus ntawm koj nco ntsoov peb lub xyoo dhau los kiv cua geek project "Server in the Clouds": peb tau tsim ib lub server me me raws li Raspberry Pi thiab tso tawm hauv lub zais pa kub. Tam sim no peb tau txiav txim siab mus ntxiv, uas yog, siab dua - lub stratosphere tos peb! Cia peb rov nco qab txog qhov tseem ceeb ntawm thawj qhov "Server in the Clouds" project yog dab tsi. Server [β¦]
Peb muaj ntau yam kev koom ua ke uas tso cai rau txhua tus khub los tsim lawv tus kheej cov khoom: Qhib API rau kev tsim lwm txoj hauv kev rau Ivideon tus neeg siv tus kheej tus account, Txawb SDK, uas koj tuaj yeem tsim cov kev daws teeb meem tag nrho sib npaug hauv kev ua haujlwm rau Ivideon daim ntawv thov, thiab. as Web SDK. Peb nyuam qhuav tso tawm qhov txhim kho Web SDK, ua tiav nrog cov ntaub ntawv tshiab thiab daim ntawv thov demo uas yuav ua rau peb [β¦]
Ceev nrooj ntes leaked secrets Nws yuav zoo li qhov yuam kev me me kom tsis txhob xau cov ntaub ntawv pov thawj mus rau qhov chaw cia khoom sib koom. Txawm li cas los xij, qhov tshwm sim tuaj yeem loj heev. Thaum tus neeg tawm tsam tau txais koj tus password lossis API tus yuam sij, nws yuav hla koj tus as khauj, kaw koj tawm thiab siv koj cov nyiaj dag. Tsis tas li ntawd, cov nyhuv domino tuaj yeem ua tau: kev nkag mus rau ib tus account qhib kev nkag mus rau lwm tus. [β¦]
