My Jekyll build takes a while, and when I’m at my machine I like to know at a glance if a build is running. I’ve gone to great lengths with notifyutil and GeekTool to put status lights on my desktop. I do the same for multiple long-running tasks. I realized the other day, though, that Growl could do this very easily, and could be automated as part of a script or Rake task.
