I-asin() esheshayo yayicashe ngokusobala

I-asin esheshayo() ibicashe ngokusobala

Emhlabeni wokuthuthukiswa kwesofthiwe kanye nokusebenza kwebhizinisi, sivamise ukujaha into enkulu elandelayo: uhlaka olusha, isizindalwazi esinamandla kakhulu, noma i-microservice architecture eyinkimbinkimbi. Sicabanga ukuthi izinzuzo zokusebenza kufanele zivele ezinguqukweni ezinkulu, eziphazamisayo. Kodwa ngezinye izikhathi, ukuthuthukiswa okubaluleke kakhulu kutholwa ngokuhlola kabusha izinto eziyisisekelo esizisebenzisa nsuku zonke. Lokhu kufanekiselwa kahle yisambulo sakamuva kukhompyutha yezinombolo: indlela esheshayo, elula yokubala umsebenzi we-arcsine, asin(), obekungenzeka ngokwezibalo ngaso sonke isikhathi kodwa kwanganakwa amashumi eminyaka emitatsheni yolwazi yokuhlela emikhulu. Kuyisikhumbuzo esinamandla sokuthi ukwenza kahle akukona njalo ukwengeza ubunkimbinkimbi—imvamisa kumayelana nokuthola indlela ecacile, eqondile. Kumabhizinisi akha kumapulatifomu ajwayelekile, lo mgomo uwuthuli lwegolide.

Izindleko Ezifihliwe Zomsebenzi Ovamile

Umsebenzi we-asin(), obuyisela i-engeli okune-sine eyinombolo enikeziwe, uyihhashi lokusebenza emikhakheni esuka kuzithombe namarobhothi kuya kwisayensi yedatha. Iminyaka eminingi, ukusetshenziswa okujwayelekile kumalabhulali afana nalawo ka-C no-C++ kusetshenziswa ifomula eyinkimbinkimbi, ejwayelekile. Le ndlela, nakuba inembile ngokuphelele, yayihilela ukulinganisa okuningi kwe-polynomial namagatsha anemibandela. Esimeni sokusebenza okuphezulu, lapho lo msebenzi ungase ubizwe ngezigidi zezikhathi ngesekhondi ekulingiseni noma amaphayiphi ezibalo zesikhathi sangempela, le misebenzi eyengeziwe iyahlanganiswa. I-overhead yekhompyutha, nakuba incane ngocingo ngalunye, ibe intela ethule ekusebenzeni kwesistimu—intela wonke umuntu ayesanda kuyamukela njengezindleko zokwenza ibhizinisi.

Ukwenza Lula Kwezibalo Kushintsha Umdlalo

Impumelelo iqhamuke ekubuyekezweni kwezibalo ezibalulekile. Abacwaningi baqaphele ukuthi esimweni esivamile sokubala i-asin(x) lapho i-x iphakathi kuka--1 no-1, ifomula elula, esebenza kahle kakhulu ingase ithathwe kusetshenziswa umsebenzi we-arctangent, atan(). Ngokuqondile, asin(x) ingabalwa njengokuthi atan2(x, sqrt(1 - x * x)). Kungani lokhu kushesha? Amaphrosesa esimanje alungiselelwe ngokukhethekile atan2() kanye sqrt() imisebenzi. Ngokusebenzisa le miyalo yezingxenyekazi zekhompuyutha ezishunwe kakhulu, indlela entsha yeqa inqwaba yezibalo ezindala, eziyinkimbinkimbi ye-polynomial. Umphumela waba umsebenzi ongelula nje kuphela kodwa ofika ku-1.5 kuya ku-2 izikhathi ngokushesha kuzo zonke izingxenyekazi zekhompuyutha ezijwayelekile, konke ngesikhathi kugcinwa ukunemba okufanayo.

"Ubuhle ekuklanyeni nasekusebenzeni kahle ekusebenzeni akukona ukucabanga; bayisisekelo sezinhlelo ezingabazekayo. Indaba ye-asin() ibonisa ukuthi isixazululo esingcono kakhulu ngokuvamile yisona esiqondana ngokuqondile ne-hardware eyisisekelo kanye nenkinga eyisisekelo."

Izifundo Zezitaki Zobuchwepheshe Bebhizinisi

Le akuyona nje indaba yonjiniyela abahlanganisayo. Isifaniso esinamandla semisebenzi yesimanje yebhizinisi. Zingaki izinqubo zakho eziyinhloko ezisebenza "ekusetshenzisweni kwefa"—ukugeleza komsebenzi okuyinkimbinkimbi, okuvamile okwakhiwe isikhathi esihlukile futhi okungakahlolwa kabusha? Ukufuna ukusebenza nokuba bukhali kuvame ukuholela izinkampani ukuthi zibophe ama-software amaningi, zenze ukwakheka okuphithene okunzima ukukuphatha futhi okunensa ukuzijwayeza. Ukuthuthukisa i-asin() isifundisa ukuthi sibheke indlela elula, eqondile ngaphakathi kwamasistimu ethu akhona ngaphambi kokuthatha ngokuthi sidinga ukushintshwa kwesikali esigcwele.

Le filosofi isenhliziyweni yenkundla efana ne-Mewayz. Esikhundleni sokuphoqa ibhizinisi lakho ukuthi livumelane nesoftware eqinile, i-monolithic, i-Mewayz inikeza i-OS yebhizinisi eyimojuli. Ikuvumela ukuthi uhlole futhi wandise ukusebenza kwakho okubalulekile—i-CRM yakho, ukuphathwa kwephrojekthi, ukuxhumana—ngokuxhuma amathuluzi asezingeni eliphezulu ngendlela ephumelela kakhulu ngangokunokwenzeka. Njengokusebenzisa asin() okusha, kumayelana nokususa ubunkimbinkimbi obungadingekile nokudala indlela esheshayo nenhle kakhulu ukusuka ku-A ukuya ku-B.

Ufuna Ukuphi I-"Faster asin()" Yakho

Ibhizinisi ngalinye linezindawo lapho isisombululo esilula, nesisheshayo sicashe ngokusobala. Qala ngokuhlola imisebenzi yakho evamile futhi ebucayi. Amakhandidethi angukhiye wokuthuthukisa ngokuvamile ahlanganisa:

• Ukunikezwa Kwedatha: Kopisha-namathisela mathupha phakathi kwezinhlelo zokusebenza noma iminyango.
• Ukuhamba Kokusebenza Okuvunyiwe: Izinqubo zezinyathelo eziningi ezincike kumaketango e-imeyili.
• Ukubika: Ukuhlanganiswa kwedatha mathupha kusuka emithonjeni ehlukene.
• Ukugibela Kwekhasimende: Ukufakwa kwedatha okuphindaphindayo kuwo wonke amasistimu amaningi.

Ngokusebenzisa i-modular mindset, ungakwazi ukuhlela lezi zinqubo. Inkundla efana ne-Mewayz isebenza njengesendlalelo esihlanganisayo, esivumela ukuzenzekelayo okungenamthungo nokugeleza kwedatha phakathi kwamathuluzi akhethekile. Lokhu kuqeda "inkimbinkimbi ye-polynomial" yengqondo yebhizinisi lakho, okukuvumela ukuthi wenze imisebenzi eyinhloko ngesivinini nobulula befomula ecwengisisiwe, eyisisekelo. Inzuzo yokusebenza ayigcini nje ngama-millisecond alondoloziwe; ingengamahora abuyiswe kabusha, amaphutha ancishisiwe, nobubhanoyi buvuliwe. I-asin() esheshayo yayihlala ikhona, ilindele ukubonwa. Ukweqa okulandelayo kwebhizinisi lakho okuphumelelayo kungenzeka kusesimweni esifanayo—esivele ungasifinyelela, silindele umbono omusha.
