Except that the population of the world only hit one billion in 1800; by 1900 it was still under two billion - now we're at seven billion. Wood doesn't scale: it pollutes, renews only slowly, and provides bulky, inefficient fuel.
In the case of the Mayans, it may have been weather change: extended drought - http://en.wikipedia.org/wiki/C... .
I bought 5 SSDs in 2014 - now in all my machines, so I'll be playing the part of (near) bleeding-edge adopter in the upcoming years. So far, am loving the performance.
I remember seeing something very much like this - http://www.gshotts.com/HUMOR/f... - billed as a "system programmer's exam" back in the '70s.
Among my favorites:
21) Sketch the development of human thought; estimate its significance. Compare with the development of any other kind of thought.
23) Define the universe in detail. List three examples.
Can't someone else do it?
Good to hear about the trans-Atlantic stupid-party co-operation.
When I was a child, we used to find old light switches and break them open to play with the mercury in them. But it did eventually kill me.
When I started in professional computing in the early '80s, there were probably 30-40% women in areas where I worked. It isn't some kind of innate preference - that tired excuse that gets trotted out to justify any conservative position.
What's changed is this idea of "tracking", as soft as it is. It used to be that a philosophy major, like myself, or an English or history major would get a programming job because most schools did not even offer CS courses, much less CS majors. Now, there is this idea of a course of study along the lines of math and engineering that leads to a career with computers. It's not any one thing that accounts for this shift, but turning the decision to work with technology from a late-stage one to an earlier, long-term one probably doesn't help. It's now like a long corridor of slight but persistent bias - highly evident in the bitter, stupid comments in this discussion - that weeds out women from the field.
Some intrepid biologists at the University of Southern California (USC) have discovered bacteria that survives on nothing but electricity — rather than food, they eat and excrete pure electrons. These bacteria yet again prove the almost miraculous tenacity of life — but, from a technology standpoint, they might also prove to be useful in enabling the creation of self-powered nanoscale devices that clean up pollution. Some of these bacteria also have the curious ability to form into ‘biocables,’ microbial nanowires that are centimeters long and conduct electricity as well as copper wires — a capability that might one day be tapped to build long, self-assembling subsurface networks for human use.

...when (leading-edge) schools were just starting to get computers. I found it to be good motivation that I was at the same level as the teachers. We were all in it together, learning this stuff for the first time.
