ABSTRACT

Designed to answer the question "What am I looking at?" when standing on a hilltop or pulled over at a scenic overlook, HeyWhatsThat.com has garnered reviews like "Just when I thought I was in danger of becoming a jaded customer of the mass mapping space, here’s a site that effortlessly returns me to a state of slack-jawed wonder" (OgleEarth). In addition to peak detection and identification, it offers viewshed computations, elevation contours, elevation profiles, and integration with Google Maps and Google Earth. This talk — given by Michael Kosowsky, designer and proprieter of HeyWhatsThat.com — will focus on what it is and how it got to be that way.

ABSTRACT

Quicksilver hides almost unbounded power beneath the interface of a keyboard-driven launcher. Using a basic grammatical model, it allows you to move beyond basic search and work effortlessly with applications, data, and the web. Quickilver is above all a prototype intended to explore new forms of interaction.

In this talk, we will explore the motivation behind Quicksilver, highlights of its implementation, lessons learned from its design, and the ways it might inform the future of navigation for the desktop and the web.

ABSTRACT

18th anniversary of BGP. In this talk we examine the evolution of BGP over these 18 years, and look at the lessons we could learn from this.

Dr. Yakov Rekhter joined Juniper Networks in Dec 2000, where he is a Distinguished Engineer. Prior to joining Juniper, Yakov worked at Cisco Systems, where he was a Cisco Fellow. Prior to joining Cisco in 1995, he worked at IBM T.J. Watson Research Center.

Yakov Rekhter was one of the leading architects and a major software developer of the NSFNET Backbone Phase II. He co-designed the Border Gateway Protocol (BGP). He was also one of the lead designers of Tag Switching, BGP/MPLS based VPNs, and MPLS Traffic Engineering. Among his most recent activities is the work on Generalized Multi-Protocol Label Switching (GMPLS). His other contributions to contemporary Internet technology include: Classless Inter-Domain Routing (CIDR) and IP address allocation for private Internets.

He is the author or co-author of over 40 IETF RFCs, and numerous papers and articles on TCP/IP and the Internet. His recent books include: "MPLS: Technology and Applications" (Morgan Kauffman, 2000) and "Switching in IP Networks: IP Switching, Tag Switching and Related Technologies" (Morgan Kauffman, 1998).

Cyrus Shahabi
Cyrus Shahabi is currently an Associate Professor and the Director of the Information Laboratory (InfoLAB) at the Computer Science Department and also a Research Area Director at the NSF’s Integrated Media Systems Center (IMSC) at the University of Southern California.

ABSTRACT
The vision of GeoDec is to enable an information-rich and realistic 3-dimensional visualization and/or simulation of a geographical location (e.g., a city), rapidly and accurately. The idea is not just to allow navigation through a 3-D model, but to be able to ask queries and get information about the area seamlessly and effortlessly. Our main focus it to build tools to quickly and cheaply integrate, visualize, and analyze all aspects of a geographic region. The ability to create high-fidelity information-rich models of cities is critical for a wide variety of decision makers. For example, in the United States, GeoDec can be used by city managers, city planners, emergency response planners, and first responders. Read the rest of this entry »

Debugging Backwards in Time

Bil Lewis

Bil Lewis is a computer scientist who has worked on natural language understanding, expert systems, language design, and programming tools. He studied at Ripon College, the University of Indiana, and Penn. He has taught at Stanford and for numerous companies. He has worked at Stanford Research Institute, the FMC AI Center, and Sun Microsystems. He wrote "GNU Emacs Lisp", the "Threads Primer", "Multithreaded Programming with PThreads", and "Multithreaded Programming with Java".

ABSTRACT
What if a debugger could allow you to simply step BACKWARDS? Instead of all that hassle with guessing where to put breakpoints and the fear of typing "continue" one too many times… What if you could simply go backwards to see what went wrong?

This is the essence of the "Omniscient Debugger" — it remembers everything that happened during the run of a program, and allows the programmer to "step backwards in time" to see what happened at any point of the program. All variable values, all objects, all method calls, all exceptions are recorded and the programmer can now look at anything that happened at any time. Read the rest of this entry »
