Visual Basic

Visual Basic, also known as the quintessential programming language for primates, is a language used to create GUIs to track IP addresses.

This incredible application has allowed many people, including the officers on the reality TV series Crime Scene Investigation, to successfully track down criminals and put them behind bars.

So far, over 3^2 * (10^2 * 10) criminals have successfully been tracked via their IP address by this amazing technology.
