The Binary Code Toolkit is an interactive learning tool for introducing how the system is used to represent meaningful data with a series of 0's and 1's.

He also introduced the backslash and escape key to the world of computers and was one of the first to warn about the dangers of the millennium bug. The millenium bug was a problem related to the need to use additional bits to represent the correct year on a computer after the turn of the century.
