E hoʻomanaʻo au iā ʻoe he hanana liʻiliʻi ke Kula SPTDC no hoʻokahi haneli a me ka hapa haneri kānaka; ʻākoakoa nā mea hoʻomālamalama papa honua ma laila a kamaʻilio e pili ana i nā pilikia o kēia wā ma ke ʻano o ka helu helu helu. ʻO Hydra kahi ʻaha kūkā helu helu ʻelua lā i mālama ʻia i ka like.

Kalulu ana
ʻElima mau lā o ke Kula i ka lālani he hanana nui loa a he nui nā hana, no ka poʻe komo a me ka mea hoʻonohonoho. ʻAʻole hiki i nā kānaka a pau i nā lā hope loa. Aia kekahi poʻe i hele i Hydra a me ke Kula i ka manawa like, a no lākou nā lā hope i lilo i mea nui loa. Hoʻopiʻi ʻia kēia haunaele e kahi kaiapuni hohonu loa. ʻAʻole kēia ma muli o ka leo wale nō, akā no ka maikaʻi o ka mea. ʻAʻole i manaʻo ʻia nā hōʻike a me nā haʻiʻōlelo a pau ma nā hanana ʻelua, no laila ma nā wahi āu e hele ai, luʻu koke ʻoe i kahi mamao a hohonu, ʻaʻole e hoʻokuʻu ʻia ʻoe a hiki i ka hopena.
ʻOiaʻiʻo, pili ka nui i ka hoʻomākaukau mua ʻana o ka mea komo. He manawa ʻakaʻaka i ka wā i kūkākūkā kūʻokoʻa ai nā hui ʻelua o ke alahele i ka hōʻike a Heidi Howard: i kekahi poʻe he mea maʻamau loa ia, aʻo nā mea ʻē aʻe, noʻonoʻo nui i ke ola. He mea hoihoi ia e like me ka poʻe i komo i nā komite papahana (i makemake e noho inoa ʻole), hiki ke hoʻokō ʻia nā hōʻike a Hydra a me nā haʻi ʻōlelo a ke Kula i kā lākou mau hanana. No ka laʻana, inā hele mai kahi ʻōpio PHP i kahi hālāwai PHP e aʻo i ke ola, he mea liʻiliʻi loa ia e manaʻo ai he ʻike hohonu kona e pili ana i nā mea i loko o Zend Engine.

Inā mākou e kamaʻilio e pili ana i nā hōʻike kikoʻī, ua maikaʻi lākou a pau ma ko lākou ala ponoʻī.

Metaconference
Ma mua o ka hoʻomaka ʻana o Hydra a me ke Kula, ʻo Ruslan Ua manaʻo ʻia aia kekahi ʻano "meta-conference" - kahi ʻaha kūkā o nā ʻaha kūkā, kahi e hoʻokomo ʻia ai nā poʻe kiʻekiʻe o nā hanana ʻē aʻe i loko, me he mea lā i loko o kahi lua ʻeleʻele. A pēlā i hana ai! Eia kekahi laʻana, i waena o nā haumāna o ke Kula i ʻike ʻia mai DeutscheBank, he loea kaulana i ka multithreading.
A o na lala Hydra i ikeia () a () mai ka hui Odnoklassniki. (Ma ka manawa like, ua kōkua pū ʻo Vadim iā mākou e hana i ʻelua mau nīnauele maikaʻi loa me Martin Kleppman - , a me nā mea ʻē aʻe no ka poʻe nānā i ka hoʻolaha pūnaewele). He mau lālā , nā mea kamaʻilio kaulana ʻo Anatoly Kulakov lāua ʻo Igor Labutin. No ka Javist aia и . ʻIke pinepine ʻoe i kēia poʻe ma nā wahi ʻokoʻa loa - dotnetists ma DotNext, javaists ma Joker, a pēlā aku. A no laila, noho pū lākou ma nā hōʻike Hydra a kūkākūkā pū i nā pilikia ma nā buffs. I ka nalo ʻana o kēia māhele hoʻokalakupua e nā ʻōlelo hoʻonohonoho a me nā ʻenehana, puka mai nā hiʻohiʻona o ke kumuhana: kamaʻilio nā loea runtime ikaika me nā runtimers ʻē aʻe, hoʻopaʻapaʻa nui nā mea noiʻi computing theory me nā mea noiʻi ʻē aʻe. .
Ma ka hoike e noho ana nā mea hoʻomohala OpenJDK ma ka lālani mua (ma ka liʻiliʻi loa, ʻike wau iā lākou ma ka ʻike, ʻaʻole naʻe ka poʻe Pythonist, aia paha nā Pythonists ma laila). ʻOiaʻiʻo, aia kekahi mea ʻo Shipilevsky i kēia hōʻike ... ʻAʻole ʻo Ori e haʻi pololei i ka mea like, akā hiki ke nānā pono i nā mea like. ʻOiai ma hope o nā mea a pau i hana ʻia i nā kūlana C ++ hou loa, ʻaʻole i hoʻopaʻa ʻia nā pilikia e like me ke ʻano o ka wai aniani, a no laila hiki iā ʻoe ke hele i kahi hōʻike a hoʻolohe i ke ʻano o ka poʻe "ma kēlā ʻaoʻao o ka pā" e ho'āʻo ana e hoʻoponopono i kēia mau pilikia, E like me kā lākou noʻonoʻo ʻana, hiki i kekahi ke hoʻohiwahiwa i nā ala i ka hopena i loaʻa (Ori kekahi o nā koho hoʻoponopono).
Nui ka poʻe i komo i nā komite papahana a me nā ʻenekini kaiaulu. Ua hoʻoponopono kēlā me kēia kanaka i ko lākou mau pilikia pili i ka hui, kūkulu i nā alahaka, a loaʻa nā pilina. Ua hoʻohana au i kēia ma nā wahi a pau e hiki ai iaʻu, a, no ka laʻana, ua ʻae mākou me Alexander Borgardt mai e kākau pū i kahi ʻatikala piha piha e pili ana i nā mea hana a me ka asynchrony ma C++.
Ma ke kiʻi: Leonid Talalaev (, hema) a me Oleg Anastasyev (, ʻākau), alakaʻi i nā mea hoʻomohala ma Odnoklassniki
Nā ʻāpana kūkākūkā ahi a me nā puʻupuʻu
Ma nā ʻaha kūkā, aia nā poʻe komo i ʻike i ke kumuhana a me nā mea haʻiʻōlelo (a i kekahi manawa ʻoi aku ka maikaʻi ma mua o ka poʻe haʻiʻōlelo - no ka laʻana, i ka wā o ka mea hoʻomohala i ke kumu o kekahi ʻenehana i waena o nā mea komo). Nui nā poʻe i komo ma Hydra. No ka laʻana, i kekahi manawa a puni Alex Petrov haʻi , nui ka poʻe i hoʻokumu ʻia ʻaʻole hiki iā ia ke pane i nā mea a pau. I kekahi manawa, ua hoʻokuʻu ʻia ʻo Alex i ka ʻaoʻao a hoʻomaka e haehae ʻia me nā nīnau, akā ua kiʻi ʻia ka hae hāʻule e kahi mea hoʻomohala Rust kaulana i nā pōʻai. a kaulike pono i ka ukana.

I kekahi manawa, ua komo ka ʻuhane o ke kūkākūkā i loko o nā hōʻike: Ua hoʻonohonoho ʻo Nikita Koval i kahi hālāwai Q&A koke, e māhele ana i ka hōʻike i nā ʻāpana.
A ʻo ka hope, ma ka BOF no ka multi-threading, hoʻomanaʻo lākou e pili ana i ka hoʻomanaʻo non-volatile, ua huki ʻia lākou i kēia bof. ma keʻano he loea nui, a weheweheʻo ia i nā mea a pau i nā mea a pau (ma ka pōkole,ʻaʻole hoʻoweliweli ka hoʻomanaʻoʻole i ka wā e hiki mai ana). ʻO kekahi o nā pūʻali o kēia bof, ma ke ala, ʻo ia , ka mea lawelawe ma nā komite papahana o kekahi helu pupule o nā hālāwai kūkā ... me he mea lā elima i ka manawa i kēia manawa. Ma ka ʻaoʻao aʻe e pili ana i ka "CS Modern i ka honua maoli" ua kūkākūkā pū lākou iā NVM a hiki i kēia ma o lākou iho.
Hiki iaʻu ke kaʻana like i ka ʻike nui ʻaʻole paha i ʻike ʻia e ka poʻe i pili pono i ka moʻolelo. Ua hookani o Eli Gafni i ke ahiahi o ka la mua o ke Kula, a i kekahi la ae, noho iho la oia a hoomaka i ka hoolele ana ia Lamport, a mai waho aku me he mea la he mea paani keia a ua lawa ole o Eli.

'Ōlelo Pelekania
ʻO Hydra 2019 kā mākou hālāwai kūkā mua kahi o ka ʻōlelo nui ʻo English. Hāʻawi kēia i kāna mau pono a me kāna mau pilikia. ʻO kahi pōmaikaʻi ʻike ʻia ʻaʻole hele wale nā kānaka i ka ʻaha kūkā mai Rūsia, no laila i waena o nā mea komo e hiki ai iā ʻoe ke hālāwai me nā ʻenekinia mai ʻEulopa a me nā ʻepekema mai ʻEnelani. Lawe nā mea haʻiʻōlelo i kā lākou mau haumāna. Ma keʻano laulā, ʻoi aku ka nui o ka manaʻo o nā mea haʻiʻōlelo koʻikoʻi e hele i kēlā ʻaha kūkā. E noʻonoʻo ʻoe he mea haʻiʻōlelo ʻoe ma kahi hālāwai kūkā ʻōlelo Lūkini loa: ua hāʻawi ʻoe i kāu hōʻike, pale i ka wahi kūkākūkā, a laila pehea? Hele a puni ke kūlanakauhale a ʻike i nā wahi mākaʻikaʻi? ʻO kaʻoiaʻiʻo, uaʻike mua nā mea'ōlelo kaulana i nā mea a pau o ka honua,ʻaʻole lākou makemake e hele eʻike i nā liona a me nā alahaka huki, ua luhi lākou. Inā ma ka ʻōlelo Pelekania nā hōʻike a pau, hiki iā lākou ke komo i ka ʻaha kūkā ma ke ʻano laulā, leʻaleʻa, hui pū i nā wahi kūkākūkā, a pēlā aku. He oluolu ka lewa i ka poe haiolelo.
ʻO ka hemahema ʻike ʻia ʻaʻole ʻoluʻolu nā kānaka a pau e kamaʻilio ma ka ʻōlelo Pelekania. Nui ka poʻe i hoʻomaopopo maikaʻi, akā ʻōlelo maikaʻi ʻole. Ma keʻano laulā, nā mea maʻamau i hoʻoholoʻia ma nāʻano likeʻole. Eia kekahi laʻana, ua hoʻomaka kekahi mau wahi kūkākūkā ma ka'ōlelo Lūkini, akā ua hoʻololi kokeʻia i ka'ōlelo Pelekānia i ka wā iʻikeʻia ai ka mea mua i ka'ōlelo Pelekānia.
Pono wau e hana i ka wehe ʻana a me ka pani ʻana o ka hoʻolaha pūnaewele ma ka ʻōlelo Pelekania wale nō a komo i kekahi mau nīnau ninaninau me nā loea. A he paʻakikī maoli kēia noʻu i poina ʻole koke. I kekahi manawa Oleg Anastasyev () ua haʻi wale mai iaʻu e noho pū me lākou i ka wā o ka nīnauele, a ua lohi au i ka hoʻomaopopo ʻana i ke ʻano o ia mea.
Ma ka ʻaoʻao ʻē aʻe, he mea leʻaleʻa i ka nīnau ʻana o nā poʻe i nā nīnau ma nā hōʻike me ke kani. ʻAʻole wale ka poʻe ʻōlelo maoli, akā ua hana maikaʻi nā mea āpau.

He ʻokoʻa loa kēia ma ʻaneʻi. ʻO ka pili ʻana, ua hoʻopau kekahi Cliff Click i kāna mau hōʻike ma mua iki, a ma hope o ka hahai ʻana o nā nīnau ma ke kaʻina hoʻomau, neʻe ke kamaʻilio ʻana i loko o ke kahua kūkākūkā - me ka ʻole o ka hoʻomaha ʻana a i ʻole ke keakea. Hoʻohana like ia i ka hui Q&A a Leslie Lamport; ʻaʻole pono ka mea hōʻike e nīnau i kāna mau nīnau, ua hele mai nā mea komo me nā mea āpau.
Aia nā ʻano mea liʻiliʻi a kakaʻikahi ka poʻe i ʻike, akā aia nō. Ma muli o ke ʻano o ka ʻaha kūkā ma ka ʻōlelo Pelekania, ʻoi aku ka māmā o ka hoʻolālā ʻana o nā mea e like me nā lau a me nā palapala ʻāina. ʻAʻohe pono e hoʻokaʻawale i nā ʻōlelo a hoʻopili i ka hoʻolālā.

Ua kōkua nui ko mākou poʻe kākoʻo iā mākou i ka hana ʻana i ka ʻaha kūkā. Mahalo iā lākou, aia mau kekahi mea e hana ai i ka wā hoʻomaha.
Ma ke ku ana hiki iā ʻoe ke kamaʻilio me nā ʻenekinia o nā ʻōnaehana multi-threaded, hoʻoponopono i ko lākou mau pilikia mai kou poʻo, lanakila i nā makana poina ʻole a loaʻa ka manawa maikaʻi.
Ma ke ku ana hiki iā mākou ke kamaʻilio e pili ana i kā lākou mau ʻōnaehana ponoʻī, ʻo ka wehe a me ka wehe ʻana: kahi waihona waihona i hoʻomanaʻo ʻia, kahi log binary puʻupuʻu, kahi microservice orchestration system, kahi halihali ākea no ka telemetry, a pēlā aku.
