wpadminbar vs godsyn.com
I play around with wordpress nightlies because I like living on the edge, breaking my own site, and fixing buggy code. Recently, in the latest nightly release wordpress decided I need an administration bar along the top of my pages. This only displays when logged in, but destroyed my theme. I do not know the official name of this bar, but it has an ID of "wpadminbar". After seeking plug-ins and settings to no avail and being let down by google, I turned to grep. The resolution is simple. To remove the bar, open wp-settings.php and comment out the following line:
require( ABSPATH . WPINC . '/admin-bar.php' );
becomes
//require( ABSPATH . WPINC . '/admin-bar.php' );
Note: If you know of an official way to disable "wpadminbar" or make it more theme friendly, please share.

Bash script to show WAN and LAN network IPs.
Following is a bash script I wrote to show my lan and wan IPs.
The script will loop every 10 seconds. Seeing as my ISP has a less than desirable up time, I use this to see when I'm finally reconnected.
