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.

What Motivates Us?

Update (04/10/2013)Came across another interesting video on the same subject (thanks to Stanislav Glozman)


Original Post (12/13/2010)Very interesting video that I found via a reference in one of the Information Technology (IT) online publications that I read on a pretty much daily basis:



I liked many things about it - the format, in my opinion, is awesome; the presentation is dynamic; and, of course, the content is quite interesting. This "new theory of motivation" departs sharply from the established practice of monetary incentives and instead emphasizes the following three intrinsic human motivators:
AutonomyMasteryPurposeI have first discovered these ideas in the book called "Cognitive Surplus" by Clay Shirky. The format was not as animated, but the ideas about these intrinsic motivators (and how they sometimes can be canceled by an addition of a monetary incentive) were interesting nonetheless. The book was a good read, though I must admit I was more impressed wit…

Country of Origin Labeling

What precipitated this post you might ask? I'll tell you what - it was The Kojo Nnamdi show, the segment aired on or around April 9th of 2012 and was titled "Buy American". It got me so fired up that I had to wait for a month or so before trying to write about it. What was I doing all this time? - Thinking about the subject matter and trying to come down. So, here's a quick synopsis (and I suggest you use the link above to listen to the whole thing online):
Despite the popularity of slogans like, "Buy American," our trade deficits continue to soar. One proposal to address the problem is more detailed country-of-origin information on products to help shift American shopping habits. Meanwhile, the United States is pursuing a “NAFTA of the Pacific” trade agreement that would lower trade barriers with several Pacific countries. We explore how these ideas might affect the economy - and prices.Want to dig a little deeper into the views of some the people from the …
