Zihlobo, size nentshukumo entsha. Uninzi lwenu lukhumbula iprojekthi yethu ye-fan geek yonyaka ophelileyo "": Senze iseva encinci esekwe kwiRaspberry Pi kwaye sayisungula kwibhaluni yomoya oshushu.
Ngoku siye sagqiba ekubeni sihambe ngakumbi, oko kukuthi, phezulu-i-stratosphere isilindele!
Makhe sikhumbule ngokufutshane ukuba yintoni eyona nto iphambili yeprojekthi yokuqala "yeServer in the Clouds". Umncedisi akazange nje abhabhe kwibhaluni, ubuqili kukuba isixhobo sasisebenza kwaye sasasaza i-telemetry yayo emhlabeni.
Oko kukuthi, wonke umntu unokulandelela indlela ngexesha lokwenyani. Phambi kokuqaliswa, abantu abangama-480 baphawulwe kwimephu apho ibhaluni inokuhla khona.
Ngokuqinisekileyo, ngokuhambelana ngokupheleleyo nomthetho ka-Edward Murphy, umjelo oyintloko wonxibelelwano ngemodem ye-GSM "yawa" esele ibaleka. Ke ngoko, abasebenzi kuye kwafuneka batshintshe ngokoqobo kubhabho kunxibelelwano olugcinayo olusekwe . Iibhaluni nazo kwafuneka zisombulule ingxaki ngentambo ye-USB edibanisa imodyuli ye-telemetry kunye ne-Raspberry 3 - kubonakala ngathi yoyika iindawo eziphakamileyo kwaye yenqaba ukusebenza. Kuhle ukuba iingxaki ziphelele apho kwaye ibhola yahlala ngokukhuselekileyo. Abo bathathu babenethamsanqa abaneethegi zabo babekufutshane nendawo yokufikela bafumene amabhaso anencasa. Ngendlela, kwindawo yokuqala sikunike inxaxheba kwi-AFR 2018 yokuhamba ngenqanawa (Vitalik, molo!).
Iprojekthi ibonakalise ukuba umbono "weeseva ezihamba ngomoya" awuphambani njengoko unokubonakala. Kwaye sifuna ukuthatha inyathelo elilandelayo kwindlela eya "kwiziko ledatha endizayo": vavanya ukusebenza komncedisi oza kuphakama kwibhaluni ye-stratospheric ukuya kwindawo ephakamileyo malunga ne-30 km - kwi-stratosphere. Ukuqaliswa kuya kuhambelana noSuku lweCosmonautics, oko kukuthi, kukho ixesha elincinci eliseleyo, ngaphantsi kwenyanga.
Igama elithi "Iseva kwi-Clouds 2.0" ayichanekanga ngokupheleleyo, kuba ekuphakameni okunjalo awuyi kubona ifu. Ngoko sinokubiza iprojekthi "Ngaphezu kwe-Cloud Server" (iprojekthi elandelayo iya kufuneka ibizwe ngokuthi "Baby, uyindawo!").
Njengakwiprojekthi yokuqala, umncedisi uya kuphila. Kodwa eyona nto iphambili yahlukile: sifuna ukuvavanya umxholo weprojekthi eyaziwayo yeLoon kaGoogle kwaye sivavanye ithuba lokusasaza i-Intanethi ukusuka kwistratosphere.
Iskimu sokusebenza somncedisi siya kujongeka ngolu hlobo: kwiphepha lokufikela uya kukwazi ukuthumela imiyalezo ebhaliweyo kumncedisi ngefomu. Ziya kuhanjiswa ngeprotocol ye-HTTP ngokusebenzisa i-2 ezizimeleyo zonxibelelwano lwesathelayithi kwikhompyutheni emisiwe phantsi kwebhaluni ye-stratospheric, kwaye iya kudlulisela le datha eMhlabeni, kodwa kungekhona ngendlela efanayo ngesathelayithi, kodwa ngejelo lomsakazo. Ngale ndlela siya kwazi ukuba umncedisi ufumana idatha kuzo zonke, kwaye inokusasaza i-Intanethi kwi-stratosphere. Kwakhona siya kukwazi ukubala ipesenti yolwazi olulahlekileyo "kuhola wendlela". Kwiphepha elifanayo lokuhlala, ishedyuli yendiza yebhaluni ye-stratospheric iya kuboniswa, kwaye amanqaku okufumana umyalezo wakho ngamnye aya kumakishwa kuyo. Oko kukuthi, uya kukwazi ukulandelela indlela kunye nokuphakama kwe "sky-high server" ngexesha langempela.
Kwaye abo bangakholwayo ngokupheleleyo, abaya kuthi oku konke ukuseta, siya kufaka isikrini esincinci ebhodini, apho yonke imilayezo efunyenwe kuwe iya kuboniswa kwiphepha le-HTML. Isikrini siya kubhalwa ngekhamera, kwintsimi yokujonga apho kuya kuba yinxalenye ye-horizon. Sifuna ukusasaza umqondiso wevidiyo kwitshaneli yerediyo, kodwa kukho i-nuance apha: ukuba imozulu ilungile, ke ividiyo kufuneka ifikelele emhlabeni kulo lonke uhambo lokubhabha kwebhaluni yestratospheric, kwi-70-100 km. Ukuba kunamafu, uluhlu lokuhanjiswa lunokuhla ukuya kwiikhilomitha ezingama-20. Kodwa kuyo nayiphi na imeko, ividiyo iya kubhalwa kwaye siya kuyipapasha emva kokuba sifumene ibhaluni yestratospheric ewileyo. Ngapha koko, siya kuyijonga sisebenzisa isignali evela kwibhodi ye-GPS ekwibhodi. Ngokwezibalo, iseva iya kuhlala ngaphakathi kwe-150 km ukusuka kwindawo yokuqalisa.
Kungekudala siza kukuxelela ngokweenkcukacha ukuba izixhobo zokuhlawula ibhaluni yestratospheric ziya kuyilwa njani, kwaye konke oku kuya kufuneka kusebenze njani kunye. Kwaye kwangaxeshanye, siya kutyhila ezinye iinkcukacha ezinomdla ngakumbi zeprojekthi ehambelana nendawo.
Ukwenza umdla kuwe ukuba ulandele iprojekthi, njengalo nyaka uphelileyo, size nokhuphiswano apho kufuneka uqikelele indawo yokumisa iseva. Ophumeleleyo oqikelele indawo yokufika ngokuchanekileyo uya kukwazi ukuya e-Baikonur, ekuqalisweni kwe-spacecraft ye-Soyuz MS-13 eqhutywe ngoJulayi 6, ibhaso lendawo yesibini isatifiketi sokuhamba esivela kubahlobo bethu baseTutu.ru. Abathathi-nxaxheba abangamashumi amabini abaseleyo baya kukwazi ukuya kuhambo lweqela ukuya kwi-Star City ngoMeyi. Iinkcukacha ku .
