I am a C programmer with 25 years experience in real time systems. If a client needs a database to track their pencils then I am the best person to come to because I understand all the implications: race conditions, middle ware, infrastructure; you name it, I know it.
But the fact is that they client will pay some guy half what I earn to knock their database up in MS Access. It will fall over from time to time but do a reasonable job.
So can I get cheap but acceptable surgery with a robot?
Yeah I think they should build it as a ground effect aircraft with non-load bearing wheels which reach down to the ground to make it technically a car.
I think VMS continued to support the install option, but I cant remember. I don't think Un*x ever did.
IIRC install in VMS was to register a privileged library with the OS. A library like that could do stuff the calling process couldn't do. Most likely it was install image.obj/priv=sysprv,setprv and so on.
My experience with RSX was with a traffic signal application called SCATS. I once interviewed for a job in a hospital where they supported ~60 users on a single machine, probably an 11/84.
Our SCATS systems had up to 16 DZ11 MUX cards for 128 serial lines. I have never seen a system which could handle that many interrupts and run so cool in the sense that it was always responsive regardless of load and it would chug away for years without showing any signs of stress.
BSD is as close as you would get to that with modern systems. Maybe QNX though I haven't worked with that OS.
It would be interesting if robots like the DaVinci could in future operate on a smaller scale and in trickier parts of the body. Some cancers (for example) are inoperable because of their location in the body. Maybe a robot could cut out most of the tumor in these cases and leave chemotherapy or radiotherapy devices behind the clean up the rest.
The tidal bulge on the Earth actually drags on the moon and increases its orbital velocity. It does this because the rotation of the Earth drags the bulge ahead of the sub-lunar point. The gravitational field of the bulge attracts the moon so the earths rotation slows as the moons orbital velocity increases. Eventually we will be tidally locked like Pluto and Charon and tides will be much smaller.
My preferred solution is to dump a whole lot of nuclear waste on the far side of the moon and turn it into a bomb. I wanted my proposal implemented by 1999 but not enough people saw the gravity of the situation.
Not only that but by converting gravitational potential energy into heat we create photons which transfer momentum to the moon and push it away faster. I propose that all future lunar landings be on the far side to compensate.
Was that in RSX11-M? I was never exactly sure how that OS hangs together but one interpretation I had was that all libraries and application processes are permanently running processes (or installed images, take your pick). So that there is one copy of the libc equivalent installed in the OS at startup and images which need it jump straight in to addresses inside that image. I spent a lot of time building applications into the OS with fingers crossed;)
I could make my wife's car theft proof by removing cables from the engine management system and bolting it to the garage floor but then she would never be able to drive it.
Time to add the Lie detector to the Ticker line...Every time someone lies on Cspan. whoop whoop whoop!
Reminds me of a federal election debate here in.au when the TV network gave each studio audience member a control box so they could indicate "like" or "don't like" for what they were hearing. The composite output was a line on the screen which quickly became called "the worm".
My mother spent her entire career teaching disabled children. One of her jobs was teaching children who were totally deaf and blind. These children had no trouble navigating out of the school, to the shop and the local park. They knew every step.
One time a child was put in a taxi to go home and the driver got the destination wrong. As soon as he went off the route his passenger told him he was going the wrong way.
Even if your ears don't work at all every nerve in your body can detect vibration, and process it as sound to some extent. Your skin can feel strong light and the temperature of the air. Your sense of balance tells you the lay of the land. Touching a person can tell you a lot about how they feel. And so on.
I didn't discuss my privacy. I discussed the technical feasibility of stopping file sharing. I reckon I could sit down right now and invent 100 totally unique ways of exchanging files across the internet. Is British legislation going to anticipate all of those and allow for them to be stopped?
Its not possible. Forget about it. Unless (as I said) you largely shut down the internet and turn it into a way of delivering television programmes, then lock up anybody who tries to recreate it.
Do you want to do that? Most the the business we rely on would cease to function. Are you ready for that?
If you had a clue about the way information is processed (not just movies and music, information) you would understand that it is impossible to legislate filtering to block the sharing of files.
The best you can hope to do is block the way they are shared now, and possibly tomorrow. If you don't like it, then shut the internet down, and all which goes with it.
And BTW, try typing slower. Your text will be more readable but I doubt it will make any more sense.
Dunno wintermute I have just moved my wife from her ubuntu laptop to a macbook pro running macos and the challenges seem much the same, even after spending money on commercial software for the mac. There ae bugs on both sides, but macos lacks the consistency brought by dpkg.
Fast rail is for passengers. Not freight. That can go by sea. Passengers need a direct route. Arcing north through Siberia and Alaska (past Sarah's place) is too slow, because even fast trains are slow compared to aircraft.
One thing I can think of is that train stops are cheaper to build than airports. You could have 100 stops along a line, but each train stops at a different 10 stops. This makes it easy to service a lot of small places without comprimising travel time too much.
I think the bigger news would be if they started work on a railway from China to the US

Righto, time to ask the serious questions! But what happens when they hit 88 miles per hour?
Accelerating or decelerating?

They better have things figured out if they're bringing a scalpel anywhere near my own personal 'mission critical component".
Its funny. We have two of almost everything else...

Been there done that... on the PDP-11 in 1979.

I'm not surprised he was out of work. His sad devotion to that ancient religion hasn't helped him find a job.
Maybe he should consider going over to the dark side.

I have a simpler conclusion... Most users are idiots!
Even simpler: most people are idiots.
I always amazes what bullshit some people come out with in order to justify their continued use of BitTorrent.
What are you talking about? I download software with bittorrent. You seem to be confusing the protocol with the content.

I could easily be wrong but I can't recall an instance of /b/ misusing a worthwhile system like the Haiti or snowmageddon applications.

We just need to cheat in the annoying form at:

Well that same form points directly to github.

I don't think its that bad. The next IBM, surely.

China has too much money and needs somewhere to put it.
