10 years ago today, Theo de Raadt started the OpenBSD project. 11 years ago today, Larry Wall released Perl 5.005. It would be difficult to overstate their contributions to software development, security, and the Internet in the intervening years. Happy anniversaries!

What’s the most important contribution of either project?
