Mouse is a largely self-taught computer geek who has been kicking around the 'net since before it was The Internet, administering systems, writing software, and answering questions since the days when it was normal for email to take a week to get from Montreal to California. He was involved with the networks that connected Montreal universities before IP networking became ubiquitous and has been contributing to the Secure Shell (secsh) working group of the Internet Engineering Task Force during the formation of RFCs 4250-4254.

Mouse has been a determined open-source advocate since before it became popular, working with NetBSD since the early '90s and working as a systems admininstrator rather than a programmer in order to avoid restrictions on writing code for distribution to the world.

Mouse's formal schooling culminated in a B.Sc. in mathematics (with a minor in computer science) from McGill.
