Ukuhunyushwa kwe-athikili kulungiselelwe ngokukhethekile abafundi besifundo se-Data Engineer. I-ClickHouse iwumthombo ovulekile wekholamu egciniwe. Kuyindawo enhle lapho amakhulu abahlaziyi angabuza ngokushesha idatha enemininingwane, njengoba kufakwa amashumi ezigidigidi zamarekhodi amasha ngosuku. Izindleko zengqalasizinda ukusekela uhlelo olunjalo zingafinyelela ku-$100 ngonyaka, futhi […]
TL;DR: Incazelo yesakhiwo seseva yeklayenti yesistimu yethu yangaphakathi yokulawula ukucushwa kwenethiwekhi, QControl. Isekelwe kuphrothokholi yokuthutha enezendlalelo ezimbili esebenza nemilayezo egcwele i-gzip ngaphandle kokucindezelwa phakathi kwamaphoyinti okugcina. Amarutha asabalalisiwe namaphoyinti okugcina athola izibuyekezo zokucushwa, futhi iphrothokholi ngokwayo ivumela ukufakwa kwama-relay aphakathi nendawo. Uhlelo lwakhiwe phezu komgomo wokwenza isipele okuhlukile (“okuzinzile kwakamuva”, okuchazwe ngezansi) futhi lisebenzisa ulimi lombuzo […]
Sixoxa ngedivayisi yokudlulisa umsindo oqonde ngqo. Isebenzisa "ama-acoustic lens" akhethekile, futhi isimiso sayo sokusebenza sifana nesistimu ye-optical yekhamera. Mayelana nezinhlobonhlobo ze-acoustic metamataries Onjiniyela nososayensi bebelokhu besebenza ngezinto ezihlukahlukene ze-metamatadium, izakhiwo ze-acoustic ezincike esakhiweni sangaphakathi, isikhathi eside impela. Isibonelo, ngo-2015, izazi zefiziksi zakwazi ukuphrinta i-3D "i-acoustic diode" - i-cylindrical […]
Muva nje, ku-inthanethi ungathola inani elikhulu lezinto esihlokweni sokuhlaziya ithrafikhi ku-perimeter yenethiwekhi. Ngesikhathi esifanayo, ngesizathu esithile wonke umuntu ukhohlwe ngokuphelele mayelana nokuhlaziya ithrafikhi yendawo, okungabalulekile kangako. Lesi sihloko sikhuluma ngokuqondile ngalesi sihloko. Sisebenzisa ama-Flowmon Networks njengesibonelo, sizokhumbula i-Netflow yakudala enhle (nezinye izindlela zayo), sicabangele amacala athokozisayo, […]
Konke okudingwa umhlaseli yisikhathi nesikhuthazo sokungena kunethiwekhi yakho. Kodwa umsebenzi wethu ukumvimbela ekwenzeni lokhu, noma okungenani ukwenza lo msebenzi ube nzima ngangokunokwenzeka. Kudingeka siqale ngokuhlonza ubuthakathaka ku-Active Directory (kamuva ebizwa ngokuthi AD) umhlaseli angabusebenzisa ukuze athole ukufinyelela […]
Ngesikhathi ngisahlala efulethini, ngahlangabezana nenkinga yejubane eliphansi ekamelweni elikude nomzila. Phela, abantu abaningi bane-router ephasishi, lapho umhlinzeki ehlinzeka nge-optics noma i-UTP, futhi idivayisi evamile yafakwa lapho. Kuhle futhi uma umnikazi efaka eyakhe esikhundleni serutha, futhi amadivayisi ajwayelekile avela kumhlinzeki afana […]
Umklomelo kaNobel waseMelika uKary Mullis washonela eCalifornia eneminyaka engama-74. Ngokusho kukankosikazi wakhe, ukushona kwenzeka ngo-Agasti 7. Imbangela ukwehluleka kwenhliziyo nokuphefumula ngenxa yenyumoniya. UJames Watson ngokwakhe, owathola i-molecule ye-DNA, uzositshela ngeqhaza lakhe ku-biochemistry futhi athole ngayo uMklomelo KaNobel. Ingcaphuno evela […]
Ekuqaleni komsebenzi wami, bengingazi izinto eziningi ezibalulekile eziwusizo kakhulu kunjiniyela oqalayo. Uma ngibheka emuva, ngingasho ukuthi okuningi engangikulindele akuzange kufezwe, kwakungasondeli ngisho nokuba ngokoqobo. Kulesi sihloko, ngizokhuluma ngezinto ezingama-20 okufanele uzazi ekuqaleni komsebenzi wakho wonjiniyela wewebhu. Lesi sihloko sizokusiza ukuthi wakhe [...]
Phakathi kwezinto ezintsha: Kuvunyelwe ukubhekisela ezinhlobonhlobo ze-enum ngokusebenzisa iziteketiso zohlobo, isibonelo nge-Self. umthengisi wezimpahla manje usefakiwe ekulethweni okujwayelekile. Ngomthengisi wezimpahla, ungadawuniloda ngokucacile futhi usebenzise ikhophi ephelele yawo wonke amakhodi omthombo kukho konke ukuncika. Lokhu kuyasiza ezinkampanini ezinama-monorepositories ezingathanda ukugcina nokuhlaziya yonke ikhodi yomthombo esetshenziswe […]
I-SimbirSoft, umholi ekuthuthukisweni kwe-fintech eRussia ngokusho kwe-Clutch, umemezele isisombululo sokudala ngokushesha izicelo zeselula kumshwalense. I-akhawunti yeselula yomnikazi wepholisi ihlanganisa: i-akhawunti yomuntu siqu yeklayenti (i-iOS, Android); iphaneli yokuphatha yomshwalense; ingxenye yeseva. Ukuhlanganiswa kwesixazululo esinebhokisi kuvumela ibhizinisi ukuthi likhiphe uhlelo lokusebenza oluhlangabezana nezidingo zemakethe ngesikhathi esifushane futhi ezinobungozi obuncane. Imisebenzi esemqoka […]
Abacwaningi abavela enkampanini ye-vpnMentor bahlonze ithuba lokufinyelela okuvulekile kusizindalwazi lapho amarekhodi angaphezu kwezigidi ezingu-27.8 (23 GB yedatha) agcinwe ahlobene nokusebenza kohlelo lokulawula ukufinyelela kwe-biometric ye-Biostar 2, olunokufakwa cishe kwezigidi ezingu-1.5 emhlabeni jikelele futhi ihlanganiswe nenkundla ye-AEOS esetshenziswa izinhlangano ezingaphezu kuka-5700 emazweni angama-83, okuhlanganisa zombili izinkampani ezinkulu […]
I-Google ishicilele uhlelo lokuqeda usekelo lwephrothokholi ye-FTP ku-Chromium ne-Chrome. I-Chrome 80, ehlelelwe ekuqaleni kuka-2020, kulindeleke ukuthi iqede ukwesekwa kwe-FTP kubasebenzisi abazinzile (ekusetshenzisweni kwebhizinisi, kuzongezwa ifulegi le-DisableFTP ukuze kubuyiswe i-FTP). I-Chrome 82 ihlela ukususa ngokuphelele ikhodi nezisetshenziswa ezisetshenziswa ukwenza iklayenti le-FTP lisebenze. Ukuncishiswa kancane […]
