Mac OS X Lion/Mountain Lion - Could not join network/timeout

I was migrating all the data from a friend's old MacBook (which was running Mac OS X Tiger) to her new MacBook Air (running Mac OS X Mountain Lion), and besides a WiFi hiccup, everything went smoothly (I had to clone the old MacBook's drive to a USB disk, then use Setup Assistant to migrate the data from that disk to the new MacBook Air).

During the Setup Assistant, I could easily connect to my WiFi network, but after the migration was complete, I couldn't connect anymore. I kept getting a pesky error: "Could not join [network]. A connection timeout has occurred." (see picture of error dialog here). Looking through Apple's forums and elsewhere was not much help, because this message seems to be a very generic 'something weird happened' error, happening in many different circumstances.

However, knowing that the keychain and old WiFi connection data from the old Mac had transferred over to the new Mac, and knowing that something might've gone screwy with the network information, I decided to do the following:

"Noli irritare leonem" – Don't disturb the lion

Someone shared a link to slides from a recent lecture put on by Credo St. Louis by Rev. Michael Witt concerning religious liberty and the current furor over the HHS contraception mandate.

Noli Irritare Leonem - Crest of Archbishop Peter Richard Kenrick

During the presentation, Fr. Witt spoke of the episcopal motto of Archbishop Kenrick, Noli irritare leonem (seen in the picture of his crest above, which I took during a visit to the Old Cathedral a few years ago). It is translated, "Don't disturb the lion," and conveys a special message today: don't try stripping us [Catholics] of our religious liberty, or you'll get the full force of our fury!*

Supercharge your Key Repeat rates in Mac OS X Lion

As an ardent keyboard-only user of Mac OS X (mice are so early 90s!), I like having a very fast key repeat rate, allowing me to hold the delete key to remove characters, command-z to undo a bunch of things in my text editor, etc.

Since I have a MacBook Air without an Eject key, I had to use KeyRemap4MacBook to switch the F12 key to behave like the Eject key for the purpose of turning off the screen with the keyboard.

This gives me another nice feature, too: the ability to have extremely fine-grained control over key repeat rates. After installing KeyRemap4MacBook, you can click on it’s ‘Key Repeat’ tab in the System Preference pane, and set your own values (in ms) for waits.

I simply set the ‘Initial Wait’ to 200ms, and the ‘Wait’ to 25ms. These values let me type, delete, and undo things very fast. That’s sooooooooooooooo spiffy ;-)
