Thursday April 19th 2001. Technical Conference, Day 3

8:30am-9:30am

Keynote - Urs Hölzle, Google Inc.

Google -- Linux Clustering for Fun and Profit

Google currently processes over 70 million queries per day for google.com and its licensees.  Despite having to search a multi-terabyte web index for every query, Google's average response times are below half a second. In this talk I'll give a technical overview of the software and hardware infrastructure that makes this performance possible.

PANEL (with refreshments), Open Source Software: Is it More or Less Secure? Moderator: Douglas Maughan, DARPA

For:   Peter Neumann, SRI International   Lee Badger, NAI Labs   Carl Landwehr, Mitretek Against:   Steve Lipner, Microsoft   Gary McGraw, Cigital

The development of software using an open-source model of software validation and distribution continues to gain popularity worldwide.

This panel of experts will explore the issues of whether this model is appropriate for ensuring the quality and assurance of software and how the open-source model impacts the assurance of software for critical systems, both commercial and military.

This is a VERY important topic, especially for the future of Internet privacy and security. Please attend and badger the panel with our opinions. There will be about an hour scheduled for audience questions participation.
