IKholamu yesine ASCII (2017)

IIkholamu eZine zeKholamu ASCII (2017) itshathi yesalathiso ilungelelanisa bonke oonobumba be-ASCII abasemgangathweni be-128 ibe yifomathi yetheyibhile yekholamu emine edityanisiweyo, ebonisa idesimali, i-hexadecimal, i-octal, kunye nemifuziselo eyimiqondiso ecaleni. Olu yilo lube sisiseko sesalathiso sabaphuhlisi, abayili benkqubo, kunye neenjineli zedatha ezifuna ufikelelo olukhawulezayo kumaxabiso ekhowudi yombhalo ngaphandle kokutyhutyha uluhlu olululuhlu olunye.

Yintoni kanye kanye iFomathi yeKholamu yesine ASCII (2017) kwaye kutheni ibalulekile?

I-ASCII - i-American Standard Code for Information Interchange - ibe yintsika yombhalo wedijithali ukususela ngo-1963. Ngo-2017, abaphuhlisi kunye nababhali bezobugcisa baye badibanisa kwi-layout yekholomu ezine njengendlela efanelekileyo kakhulu ye-ergonomically yokubonisa zonke iimpawu ze-128. Ifomathi idla ngokubonisa iikholamu zeixabiso ledesimali, elingana ne-hexadecimal, ikhowudi ye-octal, kunye noonobumba bokwenyani okanye igama lekhowudi yokulawula.

Olu lungiselelo alunamkhethe. Amehlo omntu ahlola idatha yetheyibhile ngokufanelekileyo kwimiqolo emine kunesibhozo okanye ezimbini. Iingqungquthela ze-2017 ziphinde zilungelelanise indlela abalinganiswa bolawulo (njenge-NULL, BEL, kunye ne-ESC) babhalwe ngayo, ukunciphisa ukungaqondakali kumaqela amaxwebhu. Kulo naliphi na ishishini lesoftware elilawula imibhobho yedatha, ii-APIs, okanye ukudityaniswa kwamaqonga amaninzi, ukuqonda indlela i-encoding yomlinganiswa esebenza ngayo kweli nqanaba ithintela ii-bugs ze-encoding ezibizayo ezinokonakalisa idatha yabathengi, iphule ukuhanjiswa kwefomu, okanye ibangele ukusilela okuthe cwaka kwi-automation workflows.

Ngawaphi aMalungu angundoqo weTheyibhile yeKholamu yesine ye-ASCII?

Itheyibhile ecwangciswe ngokufanelekileyo yeKholamu eSine ye-ASCII (2017) iqulathe la manqaku alandelayo edatha yoonobumba abali-128:

• Idesimali (Dec): I-base-10 inamba ukusuka ku-0 ukuya ku-127 echonga ngokukodwa uphawu ngalunye kumgangatho we-ASCII.
• Hexadecimal (Hex): Ukumelwa kwesiseko-16, okubaluleke kakhulu kwiprogram yezinga eliphantsi, idilesi yememori, kunye neereferensi zekhowudi yombala kuphuhliso lwewebhu.
• Octal (Oct): Isiseko se-8 sekhowudi esisetyenziswa ngokwembali kwiimvume zefayile ze-Unix kunye nonxibelelwano lwenkqubo yelifa.
• Umlinganiswa/uMfanekiso: I-glyph eprintwayo okanye igama elichazayo leempawu zolawulo ezingashicileliyo ezifana ne-CR (I-Carriage Return), i-LF (i-Line Feed), okanye i-NUL (Null).
• Isihlomelo sodidi: Iitheyibhile zangoku ezineekholamu ezine zihlala zibandakanya ikholamu yomxholo yesihlanu ephawula ukuba ngaba uphawu yikhowudi yolawulo, isimboli eprintwayo, idijithi, okanye unobumba - ukucokiswa okuxhaphakileyo kuxwebhu lomphuhlisi wasemva kowama-2015.

"Ukufakwa kweekhowudi kungabonakali de kuphuke. Ukuqonda i-ASCII kwinqanaba leekholamu ezine kuguqula i-encoding yeempawu ukusuka kwimfihlelo ibe yinkqubo elawulekayo, eqikelelwayo - umahluko phakathi kokuthunyelwa kwedatha ecocekileyo kunye nokulungiswa kokukhutshwa kokuveliswa kobusuku. "

Isebenza Njani iKholamu eSine ye-ASCII kwiiNkqubo zoShishino lweHlabathi lokwenyani?

Ukufaneleka kweKholamu eSine ye-ASCII kunabela ngaphaya kwereferensi yezemfundo. Enyanisweni, amashishini adibana nezigqibo ze-ASCII ze-encoding rhoqo: xa uthumela ngaphandle iifayile ze-CSV, xa uqwalasela i-webhook payloads, xa uphethe igalelo le-sanitization yefom, okanye xa kusakha udibaniso phakathi kwamaqonga e-software ahlukeneyo.

Umzekelo, iimpawu ezifana nomfanekiso wethebhu (Dec 9, Hex 09) kunye nembuyekezo yekhareji (Dec 13, Hex 0D) azibonakali kujongano oluninzi kodwa zenza umonakalo xa ziphathwa kakubi kurhwebelwano lwedatha. Ukuqonda amaxabiso achanekileyo edesimali kunye nehex - njengoko kubonisiwe kwifomathi yekholamu emine - kuvumela abaphuhlisi kunye namaqela okusebenza ukuba abhale ingqiqo yokwahlulahlula ngokuthe ngqo kunokuxhomekeka kulingo kunye nempazamo.

Iinkqubo zangoku zeshishini ezilawula imithamo ephezulu yedatha ecwangcisiweyo kufuneka iphendule ngezi nuances zekhowudi kwindawo nganye yokudibanisa. Amaqonga afana Mewayz, asebenzisa abasebenzisi abangaphezu kwe-138,000 kwiimodyuli zokusebenza ezingama-207, akhelwe ngohlobo lwengqibelelo yedatha evela ekuqondeni imigangatho esisiseko efana nokufakwa kweekhowudi ngaphakathi nangaphandle kwe-ASCII.

Ulwazi lwe-ASCII luthelekisa njani ne-Unicode kunye ne-UTF-8 kwimixholo yoShishino ka-2024?

Umbuzo oqhelekileyo ngowokuba ingaba ulwazi lwe-ASCII luhlala lufanelekile na ngoku kuba i-UTF-8 kunye ne-Unicode zilawula ukhowudo lwangoku lombhalo. Impendulo nguewe ngokucacileyo - ngenxa yezizathu ezibini.

Okokuqala, iikhowudi zokuqala ze-128 ze-UTF-8 ziyi-byte-byte ziyafana ne-ASCII. Nawuphi na umphuhlisi ochubekileyo kwiKholamu eSine yetheyibhile ye-ASCII sele eyiqonda isiseko se-UTF-8. Okwesibini, ukudityaniswa kwenkqubo yelifa, unxibelelwano lwesixhobo se-IoT, iiprothokholi ze-serial, kunye neesiphelo ze-API ezingenakubalwa zisasebenza ngokukodwa kwindawo ye-7-bit ASCII. Amashishini akhupha i-ASCII njengephelelwe lixesha ahlala efumanisa iqonga lawo "langoku" alinakukwazi ukunxibelelana ngokuthembekileyo neziseko ezingundoqo kwikhonkco labo lokubonelela.

Inzuzo yokuthelekisa ye-2017 yefomathi yekholamu emine ngokukodwa kukubandakanywa kwayo i-nomenclature yolawulo olusemgangathweni oluhambelana ne-POSIX kunye ne-RFC izimbo zamaxwebhu, okwenza ukuba isebenze ngokuthe ngqo kwiprogram yenethiwekhi kunye noyilo lwe-API kunefomathi zereferensi endala.

Ziziphi iiNgqwalasela zokuPhunyezwa ngokuSebenzayo xa usebenzisa i-ASCII Tables kwi-Data Workflows?

Ukusebenzisa i-ASCII-ukuphathwa kwedatha yolwazi kwimeko yeshishini kubandakanya izigqibo ezininzi eziphathekayo. Abaphuhlisi kufuneka baqinisekise ukuba imigca yombhobho yedatha yabo okanye igcina iimpawu zolawulo, indlela abaphatha ngayo unobumba we-DEL (Dec 127, Hex 7F) ekuqinisekiseni igalelo, kwaye ingaba i-akhawunti yabo yokunqunyulwa komtya i-akhawunti yolandelelwano lweebhayithi ezininzi xa udlula phakathi kwe-ASCII kunye neseti zoonobumba ezandisiweyo.

Kumaqela alawula imisebenzi entsonkothileyo - njengabo basebenzisa i-OS ye-Mewayz's 207-modyuli yeshishini kwizicwangciso eziqala nje kwi-$19/ngenyanga - ezi ziseko zobugcisa ziguqulela ngokuthe ngqo ekuthembekeni kokuhamba komsebenzi. Ukucoceka kokufakwa kweekhowudi kwidatha kuthetha ukungaphumeleli okumbalwa kohlanganiso, iideshbhodi ezichaneke ngakumbi, kunye nezixhobo ezijongana nabathengi ezisebenza ngokufanayo kuzo zonke izixhobo nakwiindawo.

Imibuzo Ebuzwa Rhoqo

Yintoni eyenza uguqulelo luka-2017 lwetheyibhile yekholamu ezine ASCII yahluke kwiifomati zangaphambili?

Umgangatho we-2017 uphucule izivumelwano zokuthiywa kweempawu zolawulo ukuze zihambelane nemigangatho ye-POSIX kunye ne-RFC yanamhlanje, yongeza inkcazo yecandelo elingaguqukiyo, kunye nokulungiswa kwekholamu (Dec, Hex, Oct, Char) ngendlela abaphuhlisi abajonga ngayo amaxabiso aqhelekileyo - ukuqala kwixabiso ledesimali elaziwayo kwaye lidinga i-hex elinganayo. Iifomathi zangaphambili zahluka ngokuphawulekayo ngolandelelwano lwekholamu kunye nokulebhile, idala ukruthakruthwano olungeyomfuneko ekuqhutyweni komsebenzi wamaxwebhu.

Ngaba i-ASCII encoding isasebenza kumaqonga e-SaaS ale mihla kunye nesoftware yeshishini?

Ngokuqinisekileyo. Ngelixa umxholo ojongene nomsebenzisi uye usanda kusebenzisa i-Unicode epheleleyo, isiseko sothutho lwedatha, imitya yemibuzo ye-API, ukuthunyelwa ngaphandle kwe-CSV, utyikityo lwe-webhook, kunye neefayile zoqwalaselo phantse zonke iqonga le-SaaS lisaxhomekeke kwikhowudi ye-ASCII-ekhuselekileyo yokuthembeka kunye nokuhambelana. Naliphi na ishishini elisebenza kwisikali - kubandakanywa amaqonga afana ne-Mewayz ephethe i-138,000 + abasebenzisi abasebenzayo - kufuneka iqinisekise i-ASCII-level data integrity kulo lonke iziseko zayo.

Ngaba abangaphuhlisi kwishishini banokulusebenzisa njani ulwazi lwe-ASCII ngokubonakalayo?

Abaphuhlisi bazuza kakhulu ekuqondeni ukuba ngabaphi abalinganiswa be-ASCII ababangela iingxaki kwizixhobo zoshishino eziqhelekileyo. Ukwazi ukuba iingcaphuno (i-Dec 34), i-ampersands (i-Dec 38), kunye nezibiyeli ze-angle (i-60 ka-Dec kunye ne-62) zifuna ukuphathwa okukhethekileyo kwiimeko ze-HTML kunye ne-CSV inceda abaphathi bemisebenzi, abahlalutyi bedatha, kunye namaqela omxholo avelisa ukuthunyelwa ngaphandle kokucoca kunye nokuphepha iimpazamo zokufomatha ngaphandle kokufuna ukunyuka kubunjineli kuyo yonke idatha ngokungahambi kakuhle.

Ingaba uyakha ukudityaniswa kwedatha, ukwandisa ukuhamba komsebenzi womxholo, okanye ulawula umsebenzi okhulayo kwinqanaba, ulwazi olusisiseko olufana nomgangatho we-Four Column ASCII (2017) uhlawula izabelo ekuthembekeni kwenkqubo kunye nokusebenza kakuhle kweqela. Mewayz izisa loo ngqeqesho efanayo kwimisebenzi yezoshishino - iimodyuli ezidibeneyo ze-207, izicwangciso ezivela kwi-$ 19 ukuya kwi-$ 49 ngenyanga, kunye neqonga elithenjwa ngabasebenzisi abangaphezu kwe-138,000 emhlabeni jikelele.
