Ukuphathwa Kwesigaba
Emazwaneni esihlokweni sakamuva, ubuze imibuzo eminingi mayelana nenguqulo entsha ye-Windows Terminal yethu. Namuhla sizozama ukuphendula ezinye zazo. Ngezansi eminye yemibuzo evame ukubuzwa esiyizwile (futhi namanje esisayizwa), kanye nezimpendulo ezisemthethweni, ezihlanganisa indlela yokufaka i-PowerShell nokuthi ungaqala kanjani [β¦]
Uma ulawula ingqalasizinda ebonakalayo esekelwe ku-VMware vSphere (noma esinye isitaki sobuchwepheshe), cishe uvamise ukuzwa izikhalazo ezivela kubasebenzisi: "Umshini obonakalayo uyanensa!" Kulolu chungechunge lwezihloko ngizohlaziya amamethrikhi okusebenza futhi ngikutshele ukuthi yini futhi kungani yehlisa ijubane nokuthi ungaqiniseka kanjani ukuthi ayinciphisi. Ngizobheka izici ezilandelayo zokusebenza komshini obonakalayo: I-CPU, i-RAM, i-DISK, [β¦]
Ngishicilela i-athikili yangempela ku-Habr, okuhunyushwe kwayo okuthunyelwe kubhulogi yebhizinisi. Isidingo sokwenza okuthile ngokuvumelanayo, ngaphandle kokulinda umphumela lapha futhi manje, noma ukuhlukanisa umsebenzi omkhulu phakathi kwamayunithi amaningana awenza, sasikhona ngaphambi kokufika kwamakhompyutha. Ngokufika kwabo, lesi sidingo saba yinto ebonakalayo kakhulu. Manje, ngo-2019, ngithayipha lesi sihloko kukhompuyutha ephathekayo ene-8-core processor [β¦]
Sikhuluma ngemikhiqizo emisha eyethulwe engqungqutheleni ye-VMware EMPOWER 2019 e-Lisbon (futhi sisakaza esiteshini sethu seTelegram). Izixazululo zenethiwekhi yezinguquko Esinye sezihloko eziyinhloko zosuku lwesibili lwengqungquthela kwakuwumzila ohlakaniphile wethrafikhi. I-Wide Area Networks (WANs) ayizinzile neze. Abasebenzisi bavame ukuxhuma nengqalasizinda ye-IT yebhizinisi kusuka kumadivayisi eselula ngokusebenzisa izindawo ezishisayo zomphakathi, okubandakanya ubungozi obuthile [β¦]
Ngolunye usuku, okufakiwe kuvele kubhulogi ye-Elastic, ebike ukuthi imisebenzi eyinhloko yezokuphepha ye-Elasticsearch, ekhishwe endaweni yomthombo ovulekile ngaphezu konyaka odlule, manje isikhululekile kubasebenzisi. Okuthunyelwe kwebhulogi okusemthethweni kuqukethe amagama βalungileβ okuthi umthombo ovulekile kufanele ube mahhala nokuthi abanikazi bephrojekthi bakhela ibhizinisi labo kweminye imisebenzi eyengeziwe enikezwayo [β¦]
I-MySklad API yokuqala yavela eminyakeni eyi-10 edlule. Sonke lesi sikhathi besisebenzela izinguqulo ezikhona ze-API futhi sakha ezintsha. Futhi izinguqulo ezimbalwa ze-API sezivele zingcwatshiwe. Lesi sihloko sizoqukatha izinto eziningi: ukuthi i-API idalwe kanjani, kungani isevisi yefu iyidinga, ukuthi inikeza ini kubasebenzisi, yimaphi amaphutha esikwazile ukuwanyathela nokuthi yini esifuna ukuyenza ngokulandelayo. Mina [β¦]
Uma sikhuluma nge-steganography, abantu bacabanga ngamaphekula, izingane ezihlukumeza izingane, izinhloli, noma, okungcono kakhulu, ama-cryptoanarchists nabanye ososayensi. Futhi empeleni, ubani omunye ongadinga ukufihla okuthile emehlweni angaphandle? Kungaba yini inzuzo yalokhu kumuntu ojwayelekile? Kuvele ukuthi kukhona oyedwa. Kungakho namuhla sizocindezela idatha sisebenzisa izindlela ze-steganography. Futhi ekugcineni [β¦]
Isingeniso Kwa-Shopify, siqale ukuthumela i-Istio njenge-mesh yesevisi. Empeleni, konke kuhamba kahle, ngaphandle kwento eyodwa: kuyabiza. Amabhentshimakhi ashicilelwe wesifunda se-Istio: Nge-Istio 1.1, ummeleli usebenzisa cishe ama-vCPU angu-0,6 (ama-virtual cores) ngezicelo eziyi-1000 ngesekhondi. Okwesifunda sokuqala kumeshi wesevisi (ama-proxies ama-2 ohlangothini ngalunye lokuxhumana) [β¦]
Eminyakeni embalwa edlule, iqembu lamazwe ngamazwe lososayensi abavela emanyuvesi aseMassachusetts, Pennsylvania naseMunich, eJalimane, lenza ucwaningo ngokusebenza ngempumelelo kwama-proxies endabuko njengethuluzi elilwa nokucwaninga. Ngenxa yalokho, ososayensi bahlongoze indlela entsha yokudlula ukuvimbela, ngokusekelwe kumbono womdlalo. Siye salungiselela ukuhunyushwa okushintshiwe kwamaphuzu ayinhloko alo msebenzi. Isingeniso Indlela yamathuluzi e-block bypass adumile njenge-Tor isuselwe [β¦]
Kunezindatshana eziningi ku-inthanethi mayelana nama-meshes wesevisi, nansi enye. Hooray! Kodwa kungani? Khona-ke, ngifuna ukuveza umbono wami wokuthi bekuyoba ngcono ukube ama-meshes esevisi avela eminyakeni eyi-10 edlule, ngaphambi kokufika kwamapulatifomu e-container afana ne-Docker ne-Kubernetes. Angisho ukuthi umbono wami ungcono noma mubi kakhulu kunabanye, kodwa njengoba izinsizakusebenza ziyinkimbinkimbi [β¦]
Namuhla ngizokhuluma ngomshini owodwa othakazelisayo. Bangakwazi ukushisisa igumbi ngokulibeka ngaphansi kwefasitela, njenganoma iyiphi enye i-convector kagesi. Zingasetshenziselwa ukushisa "ngobuhlakani", ngokusho kwanoma yiziphi izimo ezicatshangwayo nezingenakucatshangwa. Yena ngokwakhe angakwazi ukulawula kalula ikhaya elihlakaniphile. Ungadlala kuyo futhi (oh, Space!) usebenze ngisho. (qaphela, kunezithombe eziningi ezinkulu ngaphansi kokusikiwe) Uhlangothi olungaphambili idivayisi iphrezenta [β¦]
Kulesi sihloko sizozama ukucabangela into enjalo ethakazelisayo newusizo yengqalasizinda ye-IT njengohlelo lokuqapha ithrafikhi ye-VoIP. Ukuthuthukiswa kwamanethiwekhi ezokuxhumana esimanje kuyamangalisa: baye bahamba phambili kude nomlilo wesignali, futhi okwakubonakala kungenakucatshangwa ngaphambili manje kulula futhi kuyinto evamile. Futhi ochwepheshe kuphela abazi ukuthi yini efihliwe ngemuva kwempilo yansuku zonke kanye nokusetshenziswa kabanzi kwezimpumelelo zomkhakha wezobuchwepheshe bolwazi. Izinhlobonhlobo zezindawo [β¦]
