Joang ho bua ka sena sohle lenaneong la seboka se le seng? Ka sebele ha ho bonolo ho feta ho lekola hore na ts'ebetso e sebetsa joang lebenkeleng le lecha le benyang le ajoang le sebelisa. , empa re tla leka.
Mona ke ba seng ba le lenaneong:
(Cindy Sridharan) - moqapi oa litsamaiso o phatlalalitsoeng ho tsoa San Francisco, sengoli sa buka e khuts'oane (nka ) le tse ratoang , moo ho nang le sehlooho se le seng feela “"e ka u pholosa matsatsing a 'maloa a phomolo, empa ea u siea u thabile. Ho Hydra 2020, Cindy o tla u joetsa hore na joang , leha ba boloka naha.
Michael Scott (Michael Scott) - mofuputsi ho tloha , e tsejoang ke bahlahisi bohle ba Java e le moetsi oa ho tsoa ho Java Standard Library. Ehlile, ka Moputso oa Dijkstra oa ""le ea hae . Selemong se fetileng, Michael o fane ka tlaleho e ntle ka ho fetisisa (ho ea ka uena) ka Hydra ka , 'me joale o tla bua ka и , e fumanehang lits'ebetsong tse bapileng.
(Heidi Howard) ho tswa , e tsebahalang ka ho theha algorithm ea tumellano e ajoang , hammoho le mosebetsi oa ho akaretsa Flexible Paxos le . Selemong se fetileng, Heidi o boletse kamoo e sebetsang le ho sebetsa kateng (e 'ngoe ea litlaleho tse ntle ka ho fetisisa),' me joale ke tla leka ho tsamaea holim'a leqhoa le tšesaane pakeng tsa - mme a arolelane maikutlo a hae mabapi le hore na ke algorithm efe e molemo.
(Martin Kleppmann) mohlomong ke mofuputsi ea tummeng le ho feta ho tsoa Univesithing ea Cambridge, le mohlahisi oa mehleng oa lits'ebetso tse kholo tsa data, ea ngotseng buka e hlakileng ka mokhoa o makatsang le e ikhethang mabapi le litsamaiso tse ajoang "" Selemong se fetileng Martin mabapi le lipatlisiso tsa bona tsa CRDT, le seo re tla u bolella sona hona joale .
(Nikita Koval) ke moqapi oa li-coroutine sehlopheng sa Kotlin, mosuoe oa thupelo ea mananeo a mangata a ITMO, le setho sa komiti ea lenaneo la kopano ea Hydra (e, eona eo sehlooho sena se buang ka eona). Selemong se fetileng Nikita o buile ka ho leka meaho ea data e nang le likhoele tse ngata sethaleng sa JVM a sebelisa , mme ho Hydra 2020 eena mabapi le SegmentQueueSynchronizer - e netefalitsoeng ka ho sebelisoa etsoe abstraction bakeng sa li-programme synchronization primitives.
Latela liphatlalatso tsa rona tsa asynchronous: ka kakaretso ho tla ba le litlaleho tse ka bang mashome a mararo kopanong, re tla u bolella ka tse ling haufinyane. Hape, ha e le hantle, kopanong ho tla ba le libaka tsa lipuisano moo ho hlokahalang ho leka libui ka lipotso ka khoele e le 'ngoe kapa tse' maloa ho fihlela ho fihleloa tumellano e akaretsang.
Mme ha o le lehlohonolo, Martin Kleppmann o tla saena buka ya hao.
E, pele ho kopano ea Hydra 2020, e leng July 6-9, ho tla ba teng - sekolo sa boraro sa lehlabula ka khopolo le tloaelo ea ho ajoa komporong. E tla u fa maikutlo ao ho leng thata ho a fumana kopanong, kahoo re tla bua ka Sekolo ka poso e arohaneng.
Ho thoe'ng joale? Taba ea pele, latela litaba tse mabapi le Habré le marang-rang a sechaba (, , ).
Taba ea bobeli, haeba u se u ntse u ikutloa u e-na le takatso e ke keng ea qojoa ea ho ba teng sebokeng, hlahloba sebaka sa marang-rang, u se u ntse u ka khona .
Taba ea boraro, u se ke oa fetoa ke monyetla oa ho qoqa le komiti ea lenaneo la kopano ea Hydra 2020 litlhalosong. Litho tsa PC li tla thabela ho bua le uena ka lihlooho tsa kopano e tlang.
Ke tla u bona Hydra!
