Filmed both inside the biomes and outside, in the large and fast-maturing gardens, it follows Eden’s extreme gardening – abseiling, aerial pruning and jungle plant management, its vast planting and display projects like Bulb Mania and the appliance of science in cutting-edge pest control and quarantine techniques. Eden’s gardeners are expert in working around a fast-developing site and are expert too at imparting their practical knowledge with passion. The film aims to be a joy for all who have ever visited Eden and an inspiration for all those who have yet to be able to undertake the voyage.

Speculative Parallelization of Applications on Multicores
Google Tech Talks October 20, 2008 ABSTRACT The advent of multicores presents a promising opportunity for speeding up sequential programs via profile-based speculative parallelization of these programs. In this talk I will present a novel solution for efficiently supporting software speculation on multicore processors. Our execution model maintains the state of speculative parallel threads separately from the non-speculative state. Thus, if speculation is successful, the results of the speculative computation are committed by copying them to the non-speculative state. If misspeculation is detected, the speculative state is simply discarded. A lightweight mechanism that maintains version numbers for non-speculative data values enables misspeculation detection. Through profile-based speculative parllelization of a set of programs, our approach achieves speedups ranging from 3.7 to 7.8 on a Dell PowerEdge 1900 server with two Intel Xeon quad-core processors. Speaker: Rajiv Gupta Rajiv Gupta is a Professor of Computer Science and Engineering at the Univ. of California, Riverside. His research interests include Compiler and Architectural Support for Optimization and Software Tools for Profiling, Monitoring, and Debugging. He has published over 200 articles in refereed conferences and journals, he holds 8 US patents, and has supervised PhD dissertations of 16 students including two winners of ACM SIGPLAN Outstanding Doctoral Dissertation Award in the area of Programming Languages. Rajiv served on the Technical Advisory Group (TAG) on Networking and Information Technology created by the US President's Council of Advisors on Science and Technology (PCAST). This TAG provided input and feedback to the PCAST as it conducted a review of the Federal Networking and Information Technology Research and Development (NITRD) Program. Rajiv received the National Science Foundation's Presidential Young Investigator Award in 1991. He is a Fellow of the IEEE. He served as the Program Chair for PLDI, HPCA, LCTES and HiPEAC conferences

2008 was among the ten warmest years since reliable record keeping began. James Hansen, Director NASA Goddard Institute for Space Studies, argues that we have a much sharper knowledge of global climate sensitivity than is usually stated and that governments do not yet adequately recognize the urgency of implications for energy policy, but they must.

This is feature length video compiled from live performances flown by the Virtual Thunderbirds at the Virtual Festival of Aerobatic Teams air show in November of 2007. We strive to accurately reproduce the demo performed by the USAF Air Demonstration Squadron more widely known as the Thunderbirds. We hope you enjoy this video and that you will visit our website www.virtualthunderbirds.com as well as join our forums. We will also be performing live at VFAT 2008 this year. To find out how you can watch our live performance which will be streamed over the web please visit our forums where you can find all the details and much, much, more.
