   I can't let mentions of online code doohickeys go by without  
mentioning my
recent project: http://runroot.com/
   runroot is a web-based live REPL system.  You can run a very  
responsive erlang
shell right in your browser with full access to the underlying system.

   Backstory:  runroot was made with the intention of creating a web- 
based,
low barrier to entry erlang tutoring system.  To increase the appeal
I added another handful of languages at the last minute.  It's still  
very
early in the project's life, but so far everything is coming together  
nicely.

   Some people have been talking about C vs. Erlang again recently.  I  
wrote
the first runroot backend[1] as a cnode + libevent.  After months of  
chasing
bugs and subtle race conditions, it still didn't work properly.  I  
rewrote the
ten month old project in eight hours.  It went from 2k LOC in C to  
less than
600 LOC in Erlang (and it has more features than the 2k LOC C version!).

      Don't repeat my mistakes.
