Featured Researcher - Kishore Papineni
Kishore Papineni grew up in a “small” town in India. With a population of over a half a million people, it seemed like his childhood in Guntur positioned him for a career in engineering. “That’s what the top of the class did – either engineering or medicine,” he says.

 A Big Thinkers Event: PhotoSpread - A Spreadsheet for Managing Photos
When: Wednesday, January 23, 2008 - 11:00 - Wednesday, January 23, 2008 - 12:00 Location: Santa Clara, CA
Abstract
PhotoSpread is a spreadsheet system for organizing and analyzing photo collections. It extends the current spreadsheet paradigm in two ways:
- PhotoSpread accommodates sets of objects (e.g., photos) annotated with tags (attribute-value pairs). Formulas can manipulate object sets and refer to tags.

Featured Researcher - Brian Cooper
Like many young kids, Brian Cooper got a personal computer for his eighth birthday. The difference, of course, is that back in 1983 most people had never heard of a PC. “I’m pretty sure I was the first kid on the block with one,” says the 32-year-old Cooper.

A P2P Meta-Index for Spatio-Temporal Moving Object Databases
Source: 13th International Conference on Database Systems for Advanced Applications (DASFAA 2008), LNCS 4947, pp. 653-660, Springer, March 19-21, New Delhi, India (2008)
Abstract: In this paper we propose a distributed meta-index using a
peer-to-peer protocol to allow spatio-temporal queries of moving objects
on a large set of distributed database servers.We present distribution and
fault tolerance strategies of a meta-index that combines partial trace of
object movements with aggregated data about the number of objects in
the database servers. The degrees of distribution and fault tolerance were
compared by using discrete-event simulators with demanding spatiotemporal
workloads. The results show that the distributed meta-index
using Chord provides good performance, scalability and fault tolerance.
