Uyini umphumela we-2038?

Nsuku zonke ososayensi bamakhompiyutha benza ucwaningo ukuze bazi ukuthi izinguquko eziningi zivela kubuchwepheshe, nokho, kuyabakhathaza abaningi ukwazi. uyini umphumela ka-2038kanye nemiphumela engayibangela. Ukuze uthole konke lokhu, qhubeka ufunda isihloko esikuphathele sona.

Uyini umphumela we-2038 futhi ungawugwema kanjani ngesikhathi?

Umphumela wonyaka ka-2038 waziwa nangokuthi yi-Y2K38 emhlabeni wochwepheshe kulo mkhakha. Okungadalwa yile nkinga ukuthi kukhona ukwehluleka okukhulu kwesoftware phakathi nonyaka oshiwo.

Kodwa ... Uyini umphumela we-2038? leli phutha lihlobene eduze nomthamo omkhulu wezinhlelo ezinamabhithi angama-32. Okusho ukuthi basekela inqubo ngayinye eyenziwa ngokusetshenziswa kwamadijithi kanambambili angama-32, ngaphezu kwalokho, banenani elikhulu lezinhlanganisela ezinhle.

Uhlelo noma ikhodi kanambambili iqukethe ulimi oluyizinombolo ezisetshenziselwa ukuqonda yonke imibhalo engaphakathi kwikhompyutha. Futhi, isetshenziswa ngokuhambisana namanye amasu okubhala ngekhodi idatha, noma iyunithi yezinhlamvu.

Naphezu kokuba iphutha elikhathaza bonke abantu abanolwazi ngale ndaba, kubalulekile ukwazi ukuthi le nkinga ngeke ithinte zonke izinhlelo, kuphela lezo ezisebenzisa uhlelo lwe-POSIX noma olubizwa nangokuthi Isikhathi se-Unix.

Luyini uhlelo lwe-POXIS?

Uhlelo lwe-POSIX luqukethe inani lamasekhondi angadlula phakathi kwamabili e-UTC ngo-January 1, 1970. Nokho, isistimu yokusebenza ye-Linux Kernel inomthwalo wemfanelo wokubala kusukela ngo-21:00 p.m. ngoDisemba 31, ngonyaka ka-1969, njengoba kwenzeka icala le-Android.

Inkinga isuka eqinisweni lokuthi ikhawunta ikhombisa inombolo eyiphutha yamasekhondi, okusho ukuthi usuku lungo-1901 ngempela, hhayi u-2038 njengoba kufanele. Ngakho ukubambezeleka bonke ubuchwepheshe obungaphansi komyalo walesi simiso.

Ingabe sikhona isizinda ezindabeni ezifana nesiphazamisi sango-2038?

Ngo-Agasti 8, 2013, kwenzeka ukwehluleka mayelana nama-akhawunti anesikhathi. Ngaphandle kokungahlobene namadivayisi esijwayele ukuwasebenzisa, ingesinye sezehlakalo esifana nephutha lika-2038.

Ngaleso sikhathi, i-NASA yayinophenyo lwasemkhathini olusebenza ngenjongo yokuhlaziya ngokujulile ukwakheka kwangaphakathi kwenkanyezi enomsila. Konke kwakuhamba kahle kakhulu, njengoba yethulwa ngoJanuwari 2005.

Nokho, ngo-2013 kwenzeka ukwehluleka ukuthi kuze kube manje akanayo incazelo ephelele. Kukholakala ukuthi ngenxa yephutha kwikhompyutha egcina irekhodi lesikhathi, uthi lomkhumbi-mkhathi waphazamiseka futhi awukwazanga ukubhekisa isignali yawo emhlabeni.

Imizamo yenziwe cishe inyanga yokugcina ukuxhumana nomkhumbi, ngaphandle kokuthola impendulo. Ngalesi sizathu, umsebenzi we-NASA bekufanele uphele ngaphandle kwedatha yakamuva.

Boeing 787

Yaziwa nangokuthi i-Dreamliner, le ndiza ekhiqizwe yinkampani ye-Boeing Commercial Airplanes, naphezu kokuba iyindiza enosayizi omaphakathi futhi inesakhiwo esihle kakhulu esibonakalayo, inenkinga maqondana nesoftware yayo.

Kungase kukuthande:  Yini i-pansexual?

Isistimu yakho kagesi inephutha, futhi ngesikhathi esithile udinga ukuyivala ukuze uvimbele inkinga enkulu ukuthi ingakhiqizi, noma izinjini zendiza ukuthi zivaleke.

Ngonyaka ka-2015, kwenziwa isinqumo sokuvala uhlelo lukagesi ngesikhathi esingesikhulu kunezinsuku ezingama-248, futhi ngaleyo ndlela kuncishiswe ingozi yokuthi isibalo se-microsecond sonakaliswe ngokuphelele.

Ukuze indiza iqhubeke nokusebenza ngendlela efanele, kusungulwa iqembu elithile lokufaneleka ukuze lithathe indawo yesofthiwe futhi lenze umsebenzi walo.

Imaphi amadivaysi athambekele ekuhlulekeni?

Njengoba kushiwo ekuqaleni kwalesi sihloko, amadivaysi azobhekana ngokungangabazeki kulokhu kwehluleka yilawo anama-bits angu-32, njengoba iphutha ekubaleni kwesikhathi lilawula konke ukusebenza kwalo.

Endabeni ye-Android, amadivayisi azovinjwa ngaphandle kokuba nokwenzeka kokuwaqalisa kabusha. Enye indlela yokuhlola le theory ukuya kuzilungiselelo zefoni yakho, ubheke isikhathi nosuku, khetha unyaka ka-2038 futhi ngeke ikunikeze inketho yokufaka isicelo kulo nyaka.

Nokho, kunguqulo entsha engu-4.0.4 leso sici esisha siyengezwa. Endabeni yalokhu okungenhla, ungase uthole unyaka ka-2014, isibonelo; kodwa lapho uzama ukucinga isikhathi esithuthuke kakhulu, ikhalenda alizange likuvumele futhi libuyele osukwini losuku.

Kodwa-ke, sekunamamodeli amaningi e-Android anamabhithi angaphezu kuka-64 kuphrosesa yawo futhi angaphepha kuleli phutha.

Endabeni yesistimu yokusebenza ye-iOS, eqala ngemodeli ye-iPhone 5s, bonke abanye bavunyelwe ukuqhubekisela phambili usuku lube nguJanuwari 1, 2038, ngoba iprosesa yabo inamabhithi angu-64.

Kungase kukuthande:  Iyini i-botulism?

Yiziphi izixazululo?

Isixazululo sokuqala ukudala ama-processor angama-64-bit nangaphezulu, ngenxa yalesi sizathu izinhlelo eziningi zokusebenza zenze lesi silinganiso esisha. I-Microsoft, isibonelo, inikeza uhlelo lwe-64-bit ngaphakathi kwezinguqulo zayo; ngisho Windows 11 ayiwavumeli ama-32-bit, ngoba awasasebenzi.

Ngokunjalo, endabeni ye-macOS, yizinguqulo ezingama-64-bit kuphela ezitholakalayo, i-iOS, eqala nge-iPhone 7, ibeka nezinguqulo ezingama-64-bit ukuthi zisebenze. Ngakolunye uhlangothi, i-Android entsha enenguqulo yayo engu-5.0, nayo inamabhithi angama-64.

Ngamanye amazwi, iningi lamakhompiyutha asevele avuselelwa, ukuze kuvinjwe leli phutha ukuthi lenzeke kuwo esikhathini esizayo, futhi kuqedwe yonke idatha yawo nolwazi.

Sithemba ukuthi lesi sihloko besithandeka kuwe, uma ufuna ukwazi izihloko ezithakazelisayo, sikumema ukuthi uvakashele, ngaphezu kwalokho, ungabuka ividiyo esikushiya ngezansi.
