Digital Storage

1956 IBM's 305 RAMAC (Random Access Method of Accounting and Control) hard disk - composed of 50 24-inch discs, stacked together and taking up 16 sq ft of real estate. The once-cutting-edge monstrosity was capable of commanding an annual fee of $35,000 and stored up to 5MB of data:
Now, let's compare it to one of the contemporary storage options (averagely sized and priced) - Kingston Digital DataTraveler flash drive:
Size - 2.2 x 0.4 x 0.7 inches; weight - 5.6 ounces; capacity 16GB; price - $17.00.


So, based on these examples and by my rough estimates in the last 55 years the storage went down in physical size by over 46,000 times and in price by over 2,000 times; while storage capacity went up by about 35,000 times. Of course, this is not exactly comparing oranges to oranges, but I am sure you get the picture.

Alan Mathison Turing

Update (11/23/2013): " Now, nearly half a century after the war hero's suicide, Queen Elizabeth II has finally granted Turing a pardon." ( http://usat.ly/19bLZET ) Long overdue!!! With academic background in applied mathematics and computer science and years of experience in Information Technology it would be incredibly surprising if I didn't know of Alan Turing, or so I thought. Sure, I knew who he was and had a good idea of what he had contributed to the fields of mathematics, logic, cryptography, and of course computer science, which he basically founded; and things like Turing Machine, Turing Test, and Enigma Code-breaking have been widely popularized. I also knew that he died relatively young, but I am ashamed to admit that I didn't know anything about the circumstances surrounding his premature death. That is until I read the following in the book titled  "The Information: A History, a Theory, a Flood" by James Gleick: "Turing's hom

Tempus Fugit

I recently started reading what promises to be a very interesting book - "The Time Paradox" by Philip Zimbardo and John Boyd. It opens up quite unexpectedly with a story about Capuchin Crypt, a somewhat surreal place located under one of the churches in Rome. This is the kind of stuff one comes to expect from Dan Brown's novels (say, "The Da Vinci Code" or "Angels and Demons"), but much less so from the book, written by a psychology professor from Stanford and a research director for Yahoo!, that according to one review - "reveals how to better use your most irreplaceable resource [time], based on solid science and timeless wisdom". Wikipedia - "The Capuchin Crypt is a small space comprising several tiny chapels located beneath the church of Santa Maria della Concezione dei Cappuccini on the Via Veneto near Piazza Barberini in Rome, Italy. It contains the skeletal remains of 4,000 bodies believed to be Capuchin friars buried by their o
