Crash Course in Erlang by Knut Hellan.

This is a summary of a talk I held Monday May 14 2012 at an XP Meetup in Trondheim. It is meant as a teaser for listeners to play with Erlang themselves.
First, some basic concepts. Erlang has a form of constant called atom that is defined on first use. They are typically used as enums or symbols in other languages. Variables in Erlang are [im]mutable so assigning a new value to an existing variable is not allowed. (emphasis added)
Not so much an introduction as a tease to get you to learn more Erlang.
Some typos but look upon those as a challenge to verify what you are reading.
I may copy this post “as is” and use it as a “critical reading/research” assignment for my class.
Then have the students debate their corrections.
That could be a very interesting exercise on not taking everything you read on blind faith, how do you verify what you have read and in the process, evaluate that material as well.
Do you develop a sense of trust for some sources as being “better” than others? Are there ones you turn to by default?
