How I Start: Erlang
Thanks for the write up, especially the part on relx was enlightening. I've been toying with Erlang, and have three questions I have not been able to find good answers to. Maybe someone could elaborate?1) How well does Erlang deal with multiple VMs on a single machine? Are there any upsides to using a single VM per machine? (So, run your own code along side a RabbitMQ instance for example, if that is even feasible.)2) What is a good way to have run-time mutable configuration data? I was looking into Mnesia to store user / password combinations, but it seems a bit overkill. Ideally a solution that lets you add / remove config data from a running node on the fly.3) How do you handle access control to the node, while preserving the distributed Erlang features? VPN all machines and then only listen on the private interface?
