Re: Use of floating point numbers ?

In binary FP, 0.1+0.9 (&suchlike) is not guaranteed to be 1.0


1/10 Re: Use of floating point numbers ?

1/10 + 9/10 is just as bad. And many customers have 10 fingers on their hands, think base 19 should just work.

scan Re: documented Communicating with only obscenities?

managed to scan my copy:

At a symposium I attended in

Canada, Peter Vigor, then head of the Sandhurst Soviet Research and Study

Centre, was asked how a Soviet NCO might tell one of his men to do some

simple thing. His sample order contained, I think, seven words, five of them

variants on the soldierly expletive which the Russians, in a true spirit of

democracy, use freely through the ranks. This is a record I have only once

heard equalled. Working on a muddy side-slope, one of my Centurion crews

had just got a thrown track back on and tightened, when the track-adjusting

mechanism came away. Falling back into the mud with the 3-foot spanner

and its contents on top of him, the driver uttered the immortal phrase "The ****ing ****er's ****ed, **** it!" Perhaps Peter Vigor too was

indulging in a touch of poetic licence.

60HZ+-+- Re: " 220V on which South Korea operates"

At Princeton U, there was a student lab to measure g using a pendulum. g was off more than it should have been. The prof investigated. Turned out the wall clock (used to measure pendulum period) ran off the local power company. The clock at the power company ran off same power. When 5PM approached, the workers' hand would move the generators a bit faster, so as to get home sooner. Hence wong g.

The 8008 was cut to 16KB in order to fit into a 16-pin package



The Hebrew University got a PDP11/70 delivered, late on a Friday, on a pickup truck. They told us "600Kg, 6 packages". Turned out one package (the 11/70) was 500Kg.

We (the CS department) got it off the truck by tying ropes from it to a higher floor, letting the truck move, and putting a table to stop if moving (said table became matchwood). Let it there until Sunday, when the staff came in.

11/70 worked like a charm
