Works like a charm in Aquamacs! You’ll need to install tramp for this to work:

Singletons. Seems like they’re rarely a good idea. Ever.

Excellent series of articles by Richard Jones detailing the work required to scale a Comet server written (mostly) in Erlang out to 1 million connections.

There’s also the mochijson module in mochiweb but this looks useful in situations where the entirety of mochiweb might be overkill.

When ejabberd or Jabberlang return “error: -12″ this means they cannot load their native library drivers. Normally this means they can’t find expat_erl.so.

To fix:

1. Verify the drivers exist in the priv directory of the Jabberlang or ejabberd applications, depending on which one you’re using.
2. Verify the path, returned by ejabberd:get_so_path(), exists and is readable by the user the Erlang process is running under.
3. Make sure the shared library has been built for the appropriate platform. In other words, make sure you’re not loading a Linux shared library on OS X, for example.

May Google find this so someone else doesn’t experience the pain I did yesterday.

OMG! Reflective record access by Ulf Wiger: http://www.trapexit.org/forum/viewtopic.php?t=6385&sid=a64a45192821687eddb69fe3ae466383

Now records behave much more like how I’ve always thought they should without the mind-bendingly ugly syntax.

Hmm. Interesting reading: http://groups.inf.ed.ac.uk/links/formlets/
