As described on the web site:
An Open Spaces Conference on an Island in the Mediterranean Sea
But all attendees speak about it as an “unconference” in opposition as a traditional one. What is so different? No CFP, No speakers, No pre-planned agenda, Open Space Technology usage.
In practice, when you arrive to JCrete you don’t know about the subjects that will be discussed during the 4 days (Last day is a Hackaton). Even if the main topic is Java/JVM ecosystem, other subjects from “Self-awareness of introverts” to “Startup experiences” via “Spectre/Meltdown crash course” are discussed.
