I wrote my first working bit of Erlang code. Wasn't much code, actually. Here it is:

 
<erl>
out(A) ->
    {ok, Challenge} = queryvar(A,"hub.challenge"),
    {html,io_lib:format('~s', [Challenge])}.
</erl>
 

Wow... my highlighter doesn't even support Erlang! now it does

This a complete and finished piece of code, yes. If you heard of PubSubHubbub — that's the code to confirm all subscriptions in async mode.

The funny thing about it is the amount of code I would user to do the same in Rails/Sinatra/Whatever + erb:

 
<%= params["hub.challenge"]%>
