Comment And when it's disrupted by war or economics or ... (Score 1) 492

The problem with mitigation techniques that rely upon some ongoing activity is that when it is disrupted for any reason, the accumulated upward pressure on temperature is still there which could have sudden, catastrophic effects. (Regardless of whether I'm conviced of the anthropogenic causes of climate change.)

Comment Not just in pencil (Score 1) 962

I kid not ... we had to write our programs in Hollerith code by marking cards in pencil. They were 40-column cards so there was a little more room, and a key to the code was printed on the cards in each column to make it, well, possible if not reasonable. The idea was to get programs written offline and run by passing them through the optical card reader, lessening the demand on the handfull of terminals we had. (Maybe the teacher, who really was a good teacher, wanted to run the program himself sometimes to check the results?) In practice, we'd write and debug on the terminals, then transcribe a printout onto the cards to hand in. :-P
