I wrote [a gigantic post about internationalization in Rails](http://www.viget.com/extend/rails-internationalization-and-tu#continue) for the [Viget Extend](http://www.viget.com/extend) blog today. Go check it out to see what I've learned about that. I also learned something simple today. I'm using [MongoDB](http://www.mongodb.org/display/DOCS/Home) for something, and I wanted it to start up under OS X when I log in. [I've created a LaunchDaemon before](http://crnixon.org/articles/2008/06/29/sync-taskpaper-with-tasko.html), but I'd forgotten where to start. Once I found and read [this good article on creating your own daemons](http://developer.apple.com/documentation/MacOSX/Conceptual/BPSystemStartup/Articles/LaunchOnDemandDaemons.html), it wasn't hard from there. I ended up with: {% highlight xml %} Label org.mongodb ProgramArguments /Users/cnixon/lib/mongodb/bin/mongod run RunAtLoad {% endhighlight %} If you drop that under `~/Library/LaunchAgents`, you'll be in business.
