02/15 ENIAC demonstrated (1946) Today is the 49'th anniversary of the demonstration of the ENIAC. The ENIAC was the world's first working electronic computer, designed at Princeton University, and used to predict the state equations of Plutonium for the folks at Los Alamos who were doing nucleonics research for weapons. BTW, I will give a nice shiny new Cordoba to the first person that knows what the first computer program did, (ie., the one demonstrated.) John BTW, you lost your chance at the Cordoba. It was a Merge Sort, (and is still used today in collation of large amounts of data-the sort command in MSDOS works this way,) and was written by none other than one J. Von Neumann, (the wife of Herman Goldstine, one of the architects of the ENIAC, did the coding.) The ENIAC consisted of some 40 thousand vacuum tubes, and had 10K bytes of memory (code bloat was invented much later by Microsoft-who holds the conceptual patent.) The memory was made out of a peculiar kind of electro/mechanical/acoustical shift register, that contained a tube filled with mercury, with an electromechanical transducer at each end of the tube-with the data recirculated, synchronously, from the output transducer, back to the input transducer. Thanks for sharing that, huh? For more information, see, (in LaTeX/BiBTeX database format:) @book{Goldstine, address = "Princeton, New Jersey", author = "Herman H.
