The Perl Language by Larry Wall

“Perl is the duct tape of the Internet.“ This expressive, multi-platform, open-source, (FREE!) programming language has framed my professional life for the past ten years. The Camel Book is essential reading for anyone interested in Perl. See also Larry Wall‘s essay on Natural Language Principles in Perl. Larry Wall Quotations…

Intellectual Property on the Net by Esther Dyson

This Wired Magazine article by Esther Dyson blew me away back in 1995… “The only unfungible, unreplicable value will be people’s presence, time and attention; in order to sell that presence, time and attention outside their own community, creators will have to give away content for free.” Looking back, her prediction has largely come true!

As We May Think by Vannevar Bush

Published in 1945, this visionary essay by Vannevar Bush anticipated computers, fiberoptics, databases, and hypertext!

Introduction to Cryptography by Phil Zimmermann

From the man who brought us Pretty Good Privacy… “No data security system is impenetrable. …You have to ask yourself if the information you are trying to protect is more valuable to your attacker than the cost of the attack. This should lead you to protect yourself from the cheapest attacks, while not worrying about […]
