About conference

Joker is a conference for Java developers that’s held since 2013. It’s one of two largest and oldest Java conferences in Russia (the other is its «twin», the JPoint conference). It is the right place to go both for practical talks (say, about using Spring Boot) and getting to know JVM under the hood. The conference is held by JUG Ru Group.
