"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." --Charles Babbage (1791-1871) My: Website | Blog

I used to get silly errors like this when the log allocated space ran out. TMF
