Re: Is it just me?
On the PDP-11 in RSX-11 you could tell when the OS was idling because of the LED pattern.

MCAS. Did it drive the trim, or just load the column? I was under the impression it moved the stabilizer trim; but reading other stuff, it seems it was altering the control loading. I guess hitting the stabilizer would have the effect of loading the column anyway, but I'd like to know the full/real story.
When I worked on SIMS years ago we used to play disaster landings as a game after work on an faa phase 3 757 in Miami airport. Put the plane 5 miles out heavy mist. Then as they are lining up on descent path put an engine on fire, then give them micro burst (massive downward wind) then maybe a tough crosswind for final landing. We never even thought of automatically making the elevator tri m keep slamming the nose down with the pilot straining at full strength to pull up! That would have just been too silly to believe!
Read the book "Preventing the unthinkable" by James Martin.
Its not some namby pamby pacifist script.
Its full of physics and strategy; probably written for senior civil servants and intended
military staff of rank colonel and above.
A large scale nuclear war is quite complicated. One major physics factor in nuclear war is
most of the initial energy from a nuclear explosion is X-rays. In air these form a large fireball in the sky. In space they fly unimpeded.
Ballistic missiles (those flying in space) are very vulnerable to x-rays from space detonated
atomic weapons i.e. if you keep dropping H bombs above the country you are attacking all the missiles they launch are destroyed in flight. This has a technical term called "X-ray" lock down.
But it does not take care of cruise missiles effectively hiding from the x-rays by being in earths atmosphere.
So thats why anti ballistic missile shields (ABM) can be viewed as first strike weapons. They kind of enable a first strike as well as protecting from the odd stray north Korean missile.
Also Putin, because of ABMs, has simply increased the number of cruise and stealth nuclear delivery systems. my pennies worth. But anyone really interested should read the James Martin book
If you first used vi and are annoyed that vim does not go back into command mode
when you hit a cursor key put this in your .vimrc file.
For poeple who started using vi in the 1980's this makes vim usable.
" go back to command mode
" as soon as a curcor key is pressed

I worked in flight simulation in te late 80's and wrote assemblers for SIGMAs 2, 3, 5 and 7.
Very nice reliable old computers, size of a fridge freezer.
Bet alot are still working away, doing stuff correctly using binary scaling to do stuff we would noe do in floating point
a bit faster, but actaully with less precision...
It was a gross overreaction though, threatening prison for what really was a university prank involving computers. Anyone with a uni account can download papers, and its common practise to email them to people who you want to read them after that.
It was the criminal justice systems weapons designed for hardened criminals aimed at someone intelectual and sensitive. A criminal criminal justice system IMHO.
I have seen someone die trapped in a car in front of my eyes in a road accident.
It was a very upsetting experience.
Not silly talk. 3000 deaths a year on our roads is pretty amazingly high.
Any other `industry' would be shut down. Back to the incident I saw...
The police got there first, I was putting out the fire on the dripping exhaust pipe on the upside down car.
The ambulance and free service were probably lost (I hear they are pretty bad at navigation generally
I guess Rabiit80 if your are really an ambulance driver, you mostly arrive too late)
But I do think, on a lateral tangent here, that technology may well be the only thing to
reduce road deaths. Automatic braking systems to aid the awful human reaction times, and
monitoring via GPS to prevent people speeding (and doing a runner).
All things just around the corner so to speak.
Its mostly third parties that get harmed by speeding car drivers---speed cameras in theUK are placed where someone has died. often a child. Imagine, the child in shock half under the car mangled crying for mummy... but you would rather get from A to B 3 mins quicker....
