I’ve whipped up a nice Automator action for waking a remote machine, which works great with the new ‘wake over wireless lan’ feature in Snow Leopard.

While you need an Airport-type router to get the most of the feature, there’s nothing stopping you sending the magical ‘wake up’ signal from any other computer.

Here’s a screenshot of how you might want to try and use it in a workflow:

Download the Wake Machine action here, and the source is on github.

It may only work if you are on the same network, depending on how you are set up, but regardless, it’s great to be able to wake up my Mac mini from my laptop, automatically, and whenever I want.

With the latest release of my vanity gem creation tool, I’ve made it a tiny bit simpler to turn an existing project into a gem, by valthropomorphosizing gem-this into a gem command. BEHOLD:

$ mkdir my_lib
$ cd my_lib
$ mate sweet_codez.rb
# .... hack away
$ gem this

Note the lack of hyphen! That’s right, it’s as if gem-this was built directly into rubygems itself. Take that!
