Bye Bye Mongo, Hello Postgres
Was is most surprising (well, not really), is the apparent immaturity of Scala tooling (Ammonite), and Akka-based projects like Akka-HTTP and Akka-Stream. If you can get into very cryptic issues when using these project, it makes you reconsider the actual value you get from using a functional, type safe and on-paper concurrent language.<p>Their proxy is one example where Rust will give the same capabilities as Scala and will be more robust, in the future, if it's not already the case today.
