[FOSDEM] How was the final list of devrooms built?

Hi, Year over year I am watching the procedure for compiling the final list of devrooms and each year I am surprised. I know each year there are a lot of devroom submissions and a lot of competition. But how is the final list compiled? It would be nice if this process is more open with the community. I can see there is a devroom for Ada and Dart but no devroom for Rust or C++. There is a devroom for MySQL and MariaDB and no devroom for *all* NoSQL systems combined. Are there no free nosql databases? Were there no devroom submissions for Rust or other emerging programming languages? Thanks, -- Konstantin Osipov, Moscow, Russia
