Construction of extractors using pseudo-random generators, STOC99. Extracting Randomness from Samplable Distributions, FOCS00. Unbiased bits from sources of weak randomness and probabilistic communication complexity. I will describe recent applications that use the graphical structure of the Web to improve search engine results. I will also describe the process of acquiring Web data and storing it in a way that facilitates large-scale computation.
Similar results hold for space.
We will look back at Zak's version of the argument for these results. A computer processor consists of multiple components such as functional units, cache and main memory. At each moment of execution, a program may have a varied amount of work for each component. Recent research has exploited this imbalance to save energy by slowing the components that have a lower load. Symmetrical to reconfiguring hardware is reorganizing software.
