[cctalk] Re: NSA releases copy of internal lecture delivered by computing giant Rear Adm. Grace Hopper

Nice, thanks! My wife and I still remember attending a lecture by Grace Hopper at DEC. For a while she, and a handful of other early computer pioneers, was a DEC employee and traveled widely delivering lectures on her work. A detail we both remember well is her way to let the audience understand the small time units that computers work with. She showed us a foot-long piece of wire and said "This is a nanosecond". (I just worked out the corresponding visualization for a picosecond: a grain of salt. Hm...) paul
