Getting my ar5212 wifi card to search for an access point

On ubuntu karmic, I uninstalled network-manager and tried to configure my Thinkpad T41p's ar5212 wireless connection manually.

iwconfig wlan0 essid MyEssid
iwconfig wlan0 txpower auto

When I run iwconfig, it says "not associated" and doesn't appear to be looking for an AP. It'll stay like this forever.

But if I run dhclient wlan0, within a few seconds it'll associate and get an address as expected.

sudo sucks

sudo helpfully won't let you do anything as root anymore if you disturb its precious 440 permissions. Because, you know, having root be able to write the file would be INSECURE. FML.

Edit: Whee!! It even helpfully segfaults on karmic:

$ sudo bash
sudo: /etc/sudoers is mode 0640, should be 0440
Segmentation fault

Avoiding the annoying "no write since last change" vim message

Whenever I'm on a new machine, it drives me nuts when the default vi install won't let me :bn without saving first. Adding ":set hidden" to my .vimrc fixes that, letting me switch buffers without saving first.
