CS50

A December 2005 guest lecture by Mark Zuckerberg in Harvard's CS50, discussing Facebook's early days, its technical choices and computer science. It captures him as a 21-year-old founder before Facebook's rise.
HN commenters mine it for early-Facebook history, such as his view on open source, privacy and the problems that shaped its architecture.
