Dan Frankowski University of Minnesota Privacy Risks of Public Mentions on: Google TechTalks It is common to segregate different aspects in different places: you might write opinionated rants about movies in your blog under a pseudonym while participating in a forum or web site for scholarly discussion of medical ethics under your real name. However, it may be possible to link these separate identities, because the movies, journal articles, or authors you mention are from a sparse relation space whose properties (e.g., many items related to by only a few users) allow re- identification.
A Human Story of Computer Animation on: On May 16, four self-described geeks-each with a passion to make animated movies-share how they discovered computer animation, and what obstacles they had to overcome in the process. They will present the entertaining and inspiring tale of how they went from an idea, to a script to the drawing board, to mathematics, to the computer lab...and ultimately to their Oscar acceptance speeches. Come hear their personal experiences with early computers-which had been developed for code breaking and complex computations-and how they were transformed to allow development of some of the most memorable images in pop culture today. This rare union of friends-pioneering artists and scientists-represents a momentous evening in animation history. The movies and innovations of these award-winning pioneers sit at the intersection of technology and art.

The Origins of Zelenograd: The Amazing Story Of Two U.S. Engineers In Cold War Russia on: Author and BioCentury Publications Senior Editor Steve Usdin tells the fascinating story of two American engineers, Joel Barr and Alfred Sarant, who were recruited into espionage by Julius Rosenberg, and, driven by ideology, evaded the FBI and escaped to carry on their work on behalf of the Soviet state. Barr and Sarant rose to the pinnacle of power in the Soviet establishment and managed the building of the postwar modern Soviet military machine and microelectronics industry. Based on new files and a personal friendship with the late Barr, who gave Usdin interviews and letters revealing his entire life story, Usdin shares new stories on computing during the Cold War and how Zelenograd, the Soviet Silicon Valley came to be.

A Dozen Precursors of Fortran on: The history of a subject helps us not only to understand how the important ideas were born but also to appreciate the amount of progress that has been made. The history of programming languages is a striking example, because basic concepts that we now regard as self-evident were by no means obvious a priori; many years of hard work by brilliant and dedicated people were necessary before these basic principles were learned.
Clay Shirky New York University Clay Shirky, Making Digital Durable - Seminars About Long Term Thinking on: Google Video "THIS is what the Internet has been straining to become," said Clay Shirky Monday night, both joking and meaning it. He was referring to a category ("tag") which emerged from users on the photo-sharing site Flickr. The category is "cats in sinks."...Shirky pointed out that "cats in sinks" has none of the limitations of former category systems such as the Dewey Decimal System or the Library of Congress scheme or Yahoo's hierarchical category structure. There is no need for a category "cats" with subcategory "in sinks," nor a category "sinks" with subcategory "cats in".
Pixels and Me on: Computers have revolutionized image media. Richard Lyon, one of the current pioneers of digital cameras, has found that several generations of pioneers in this field have been entangled with the terms picture element and pixel and that studying the history of the terminology is a fruitful approach to the history of the people and technology. Vladimir Zworykin's television research group at RCA popularized the term picture element in the 1930s, while the TV researchers at Bell Labs ignored that term, preferring image element. Fred Billingsley and others at the Jet Propulsion Laboratory developed computerized image processing and propagated the term pixel in the 1960s, while image processing researchers at Bell Labs ignored that term, preferring pel. In the early 1970s, pixel was spread through computer image processing publications from NASA, USC, IBM, Stanford, University of Missouri, and other places, eventually coming to be applied to elements of image sensor hardware, such as Lyon's optical mouse in 1980 and digital camera sensors more recently. Many of the people involved in this complex history have provided their personal recollections and documents to help piece the story together, and more such inputs will be solicited from the Computer History Museum audience.
