This references an IBM study, which is what I think I actually remember but could not find quickly this morning.
"In a study by IBM, it was noted that errors in cache memory were twice as common above an altitude of 2600 feet as at sea level. The soft error rate of cache memory above 2600 feet was five times the rate at sea level, and the soft error rate in Denver (5280 feet) was ten times the rate at sea level."
IBM research is a wonderful resource in the area of soft errors. I do remember exactly reading your quote, I didn't bother to track the exact article, but it should be part of this special issue
http://www.research.ibm.com/journal/rd40-1.html, the banner article mentions Denver but doesn't have the exact quote. The web shows it would be "Terrestrial Cosmic Rays", the second article in that issue.
They have a more recent special issue on the same subject
http://www.research.ibm.com/journal/rd52-3.html
Personally, "Object-Oriented Software Construction, Second Edition" opened my eyes. It is not a computer language, even if it is basically also presents a strong rationale for Eiffel, but it presents the concepts of OO in a clear and understandable way.
Just a small correction, the kilogram is defined by a platinum-*iridium* alloy artifact. The addition of iridium was important to guarantee the best possible stability
Believe or not, but there is even a competitive market for developing new Atari 2600 games. On top of the one mentioned in the Extreme Tech article, there is also the one shown at http://www.vgwiz.com that also provided bank switching solutions. Talk about resiliency for the Atari 2600.
