Rewrite incoming CallerID
We’re using asterisk, and as part of the dial plan, a 9 is required before the number to make calls out to the PSTN. Since our phones have a incoming call log, it would be very convient to have asterisk rewrite the CallerID value on calls from the PSTN to include this leading digit. I [...]
Asterisk GotoIf Application
The description from asterisk for this is GotoIf(condition?[labeliftrue]:[labeliffalse]), however for me (being somewhat new to asterisk, and not fully understanding all the little bits, this was a bit confusing.

Quick install of Tomcat5 on CentOS

Launch Google Chrome and external links with incognito mode.
The instructions floating around are to place the --incognito switch (single – works fine for me) in your desktop shortcut. But sometimes you may be in an application like Tweek Deck, etc that links to webpages. These pages don’t launch in incognito if you only fix your desktop shortcut. Here is how to do both. [...]

Installing Dropbox on Ubuntu (and others)
I’ve been using dropbox to sync and share files between my various computers for quite some time, and overall have been very pleased. However, one area things are not so great… documentation for installation on Linux. After having to reinstall on my notebook, I decided to somewhat document the hidden part of the process.

Modify Windows XP routing table
During some network changes I’ve found the need to modify the routing table.
To change the default route on Windows XP (and possibly Windows Vista, 2000, etc) you use the route command. The syntax is pretty simple, here is a quick example….

To delete or add routes, simply change the keyword [...]
