I decided to have a brief play around with Erlang a couple of weeks ago. If you don’t know what it is already, you are unlikely to be interested, so switch off now. On the other hand if you do know what it is, I’m sure you know more than me about it, so switch off now. That leaves me writing for my future self, who is probably here either trying to refresh his goldfish-like memory or wanting a chuckle at what his former self got wrong.
