-^ Telefontornet in Stockholm, around 1890. Used until 1913.

-^ Telephones were operated manually at Switchboards. Anyone old enough to remember? I'm certainly not.

-^ Eventually we did that in software, and we got better at it over time. Ericsson AXD 301, first commercial Erlang switch. But lets take a step back.

-## Phone switches must be ...
-
-Highly concurrent
-
-Fault-tolerant
-
-Distributed
-
-(Fast!)

-## ... and so is Erlang!
-
----
-
-## Erlang as a whole:
-
-- Unique process model (actors!)
-- Built-in fault-tolerance & error handling
-- Distributed processes
-- Three parts!
-
----
-
-## Part 1: Erlang, the language
-
-- Functional
-- Prolog-inspired syntax
-- Everything is immutable
-- *Extreme* pattern-matching
-

-### Hello Joe
-
-```erlang
-hello_joe.
-```
-
----
-### Hello Joe
-
-```erlang
--module(hello1).
--export([hello_joe/0]).
-
-hello_joe() ->
-    hello_joe.
-```
-
----
-### Hello Joe
-
-```erlang
--module(hello1).
--export([hello_joe/0]).
-
-hello_joe() ->
-    hello_joe.
-    
-% 1> c(hello1).
-% {ok,hello1}
-% 2> hello1:hello_joe().
-% hello_joe
-```
-
----
-### Hello Joe
-
-```erlang
--module(hello2).
--export([hello/1]).
-
-hello(Name) ->
-    io:format("Hello ~s!~n", [Name]).
-
-% 3> c(hello2).
-% {ok,hello2}
-% 4> hello2:hello("Joe").
-% Hello Joe!
-% ok
-```

-
-## [fit] Hello ~~world~~ Joe is boring!
-## [fit] Lets do it with processes.
-

-### Hello Server
-
-```erlang
--module(hello_server).
--export([start_server/0]).
-
-start_server() ->
-    spawn(fun() -> server() end).
-
-server() ->
-    receive
-        {greet, Name} ->
-            io:format("Hello ~s!~n", [Name]),
-            server()
-    end.
-```
-
----
-
-## [fit] Some issues with that ...
-
-- What about unused messages?
-- What if the server crashes?
-
----
-
-## [fit] Part 2: Open Telecom Platform
-
-### **It's called Erlang/OTP for a reason.**
-
----
-
-# OTP: An Application Framework
-
-- Supervision - keep processes alive!
-
-- OTP Behaviours - common process patterns
-
-- Extensive standard library
-
-- Error handling, debuggers, testing, ...
-
-- Lots more!
-
-^ Standard library includes lots of things from simple network libraries over testing frameworks to cryptography, complete LDAP clients etc.
-
----
-
-# Supervision
-
-![inline](http://erlang.org/doc/design_principles/sup6.gif)
-
-^ Supervision keeps processes alive, different restart behaviours, everything should be supervised to avoid "process" (and therefore memory) leaks
-
----
-
-# OTP Behaviours
-
-* `gen_server`
-* `gen_statem` 
-* `gen_event`
-* `supervisor`
-
-^ gen = generic. explain server, explain statem, event = event handling with registered handlers, supervisor ...

-## [fit] Part 3: BEAM
-
-### Bogdan/Bjørn Erlang Abstract machine
-
----
-
-## A VM for Erlang
-
-* Many were written, BEAM survived
-* Concurrent garbage-collection
-* Lower-level bytecode than JVM
-* Very open to new languages
-  (Elixir, LFE, Joxa, ...)
-
----
-
-## What next?
-
-* Ole's talk, obviously!
-* Learn You Some Erlang!
-  www.learnyousomeerlang.com
-* Watch *Erlang the Movie*
-* (soon!) Join the Oslo BEAM meetup group
