Successful libraries arguably achieve the right balance among these software engineering dimensions:   1. requirement, i.e., fulfilling the correct anticipated needs;   2. architecture, i.e., being easily composable with others and evolvable as new requirements surface; and   3. scalability, i.e., using efficient algorithms and providing further means to customize and compose them for performance. This talk relates software engineering lessons learned by the speaker while writing a number of widely used libraries.

Arbaugh, University of Maryland, College Park Computing devices are shrinking while becoming more powerful. At the same time, several forms of wireless networking are experiencing exponential growth. What happens when these two trends converge, and what does it mean for security? This talk will provide a short (and pitiful) history of wireless network security, followed by the speaker's view of the future of wireless network security and what security challenges must be solved before true ubiquitous computing can emerge.

This talk discusses deployed systems or standards with such flaws. It includes a public-keyxbased system with no advantages over a secret-keyxbased system, one in which encryption was used where what was really needed was integrity protection, one in which adding security decreased the reliability and did nothing to enhance the security of the system, unmanageable or unscalable PKI models, and an email standard that allowed forging signatures.

Miller, University of Wisconsin CUP: Controlled Update Propagation in Peer-to-Peer Networks Mema Roussopoulos and Mary Baker, Stanford University	INVITED TALKS The NPACI Rocks Cluster Toolkit: Breaking the Myth of Homogeneous Clusters Philip Papadopoulos, San Diego Supercomputer Center The Rocks toolkit allows users to stand up small, medium, and large-scale x86 and IA64 clusters in a short period of time. It starts with the assumption that clusters are heterogeneous in both hardware and functionality. Rocks decomposes the configuration of nodes (termed appliances) into small, reusable building blocks that include both software package and configuration information. Using a graph construction, shared configuration information across appliance types can be easily expressed. Utilizing the extensive hardware probing of modern OS installers, heterogeneous nodes become no harder to support than assumed homogeneous nodes. Installation and reinstallation performance figures will be given.	FREENIX TRACK File Systems Session Chair: Chuck Lever, Network Appliance Awarded Best Paper!

The Game of the Name) Steve Hotz, New.net Naming is a fundamental concept for systems architects, a critical decision for marketers, and a requirement for operating networked computers. Quite simply, we care about names. Consequently, it is no surprise that control of the DNS, the primary Internet namespace, is a morass of highly charged technical, financial, legal, and political issues. This talk discusses issues surrounding alternative top-level domains, and the somewhat controversial approach New.net has taken to expanding the operational DNS namespace.

Salus, Matrix NetSystems It's a bird! It's a plane! Look! Up in the sky . . . If no one could agree on Superman, no wonder we aren't quite certain what the Internet looks like when it goes home to Smallville and takes off its Clark Kent suit. Thirty years ago, when the ARPAnet had well under 50 hosts, the diagram was easy; 20 years ago, when the number was 400, it could still be mastered. But today there are well over 200 million hosts. Several different approaches are currently being pursued to represent the stucture and population of the Internet, and much of the data is muddled and inconsistent. Thus, part of the challenge is to gather it into a coherent representation of what's out there.

Storrs Hall, Institute for Molecular Manufacturing Designing a microprocessor has more in common with programming than it does with designing a steam engine. Similar tools—specification languages, simulators, rule checkers, profilers—and a similar level of complexity dominate over the distinction between matter and bits as the output. As nanotechnology advances to the point where we can specify and construct large, atomically precise systems, the same will become true of nanomachine design.

INVITED TALKS Infrastructure for Feature Film Visual Effects, or, Herding Cats in a Thunderstorm Wook, Consultant Contemporary feature film visual effects generally require a large digital (CGI—Computer Generated Imagery) component. The peculiar economics of this sector and how to scale to provide near-real-time response in addition to generating and integrating complex image sets will be discussed. The major infrastructure issues in this talk have to do with networking, multi-terabyte storage, the futility of backup, distributed processing, and asset management.
