spis to chce mit nejakou korelaci mezi tim co umim a tim co trh poptava. a kdybych investoval 2 roky zivota do studia neceho cim bych se v zemich koruny ceske neuzivil mi neprijde dobra vyhlidka.
trochu trollim, na 10000% procent v anglii nebo v nemecku se takova prace da sehnat. ale co jsem poslouchal jaky jsou komplikace sehnat treba praci v UK tak nevim... jednou me napadlo jen tak hledat nejakou praci na slovensku. ftip je v tom, ze pri kliknuti na tlacitko vyhledat se zmeni domena.sk na domena.cz a pak se standartne hleda. ale pouze v CR :D :D
Jen tak pro priklad: WhatsApp, Facebook messenger, Battle.net bezi na Erlangu (backend)
Erlang pouzivaji i nekteri mobilni operatori, protoze to je prostredi kde vznik (Ericsson). Akorat se tim moc nechlubi. Dejte do Google Erlang jobs a uvidite. Vyuziti je, jenom je velice specificke.
Facebook přepsal chat z Erlangu do C++ - viz třeba http://www.quora.com/When-did-Facebook-switch-away-from-using-Erlang-for-Facebook-Chat/answer/Ben-Maurer
At the time Facebook switched away from Erlang, the chat system had numerous reliability issues. The Erlang servers (which were used to provide long-poll functionality for browsers) caused some, but certainly not all of the problems. One problem we found with Erlang was that some of the abstractions Erlang had that allowed one to transparently have a distributed system across multiple machines actually caused reliability problems -- one server in the group would fail and cause cascading issues. Secondly, we found a number of instances where Erlang wasn't scaling well to multiple cores.
I don't think these issues are necessarily fundamental flaws of the Erlang runtime. It's quite possible that there was tuning that would have made Erlang work better for us (in fact, in our investigations we found a few tuning options that helped us).
However, Facebook has a number of useful abstractions in C++, making that a logical replacement.
