> It turns out that many of the traits of Erlang systems overlap with that of the Rovers. But I don't think this is a coincidence. The software has certain different properties — the rovers are hard realtime whereas the erlang systems are soft realtime.
> The things that do not overlap has to do with the need of having soft realtime vs hard realtime. In Erlang we can yield service. It is bad, but we can do it. On a rover it can be disastrous. Especially in the flight control software. Fire a rocket too late and you are in trouble.
