Comment stack instructions? (Score 1) 169

The model 360 was the first machine I coded in assembler. I didn't realize until I learned assembler on a more sophisticated machine (an XDS mainframe) that the 360 didn't have stack instructions (i.e., push registers onto or pull registers off a stack).

Does anyone know whether IBM ever added push/pull instructions to their mainframes?

... red lights are staggered so that you will have to stop at every single one of them...

Around here, the traffic control idiots time lights so that you stop at every other traffic light. I've experimentally determined if you drive about 48mph in a 40mph zone, you'll rarely stop.

OTOH, cops love speeders, so this is not an optimal solution. The optimal solution is to time lights so as to present as few red lights as possible, but people in government around here are generally complete losers.

From what I undertsand, the enigma machine was very well designed (it was made by the Germans) and should have been impossible to crack if it wasn't for Mr Turning and his amazing brain.

Not to take anything away from Turing's brilliant work, but his Enigma accomplishments were based on the work of Polish cryptologists Rejewski, Rozycki, and Zygalski, who were breaking Enigma messages in 1932 [http://en.wikipedia.org/wiki/Enigma_machine/].

You know not every situation has to be analogized to Hitler. Those that constantly make those analogies only crush the credibility of their arguments.

George Santayana famously said, "Those who cannot remember the past are condemned to repeat it."

Not every situation has an analogy to Hitler. Many that do have an analogy are worth repeating.

After all, if it's monitored three shifts then it shouldn't have to notify anyone offsite.

You obviously never worked in the data center where I worked. It could be (and sometimes was) 90 degrees on the raised floor, yet the ops staff couldn't be bothered to open the door and check.

The model, the oldest in the Boeing 777 family, has a range of 5,240 nautical miles (9,700 kilometres), according to the Boeing website. Its typical cruising speed at 35,000 feet is Mach 0.84.

Ya gotta consider if this aircraft was flying below radar, it was guzzling Jet A like there was no tomorrow. Its range will be nowhere near 5,000 miles under the condition of low altitude flight.

I only fly the little stuff. If there's a pilot around who flies the fanjet stuff, can he comment on a possible maximum range at low altitudes?
