Lit. Buffer overruns 1708

Ok. I'll try to watch for different meanings. So far, I hadn't detected any. Note that there are many ways to "allocate" many flavors of space.

I understood your use. I was trying to describe that this is not a simple technique that can be taught in example 1 of the text for Computing Clbutt 101. I, perhaps, simplified what I wrote too much but I wanted to avoid showing fat, juicy worms in the can you have not seen :-)).

Some days it is. Other days, it's not. It really depends on the app, the OS philosophy, the hardware and a slew of other stuff.

Overrun in that case was having the bits in a buffer spill over the edges. Underrun is thinking you've filled your buffer but didn't.

I, an app program, request 100K core from the monitor. In order for it to give me that much core it has to swap out a job that will free up 100K. The only job that can be swapped out to make enough core available to me is my job.

Now put your OS hat on: How do you, as an OS, deal with that?

Yup.

Nope. Given a user command, made at monitor mode just before running the application, a job's limits can vary drasitcally.

For instance, a user command that sets memory size limits for the job (or task). I see user commands that set buffer numbers.

On the -10, if a user could set a parameter, then the parameter had to be settable by a program, the sysadmin, the OS build procedures, sometimes the hardware, and all had to be able to unset it and-or correct it.

Yup. My methods of defending against that on these toys I use, is to have the keyboard code where any overwriting will cause keyboard freezure.

Sure. All they need is to be told.

The problem is that, if your lecture is one lecture, and these kids never hear nor encounter the concept on a daily basis, they will forget that such a thing can happen. I was told once when King fill in blank died. It isn't a fact that I have used at all (until now) so even the existence of King whomever has been forgotten.

IMO, that horse is still kicking :-). We may be confusing stuff but that's why it needs to be yakked about.

Yup. That's what my neighbor said. We double-whammied it because I gave her my old snowblower. Now that we both are well-girded with vrroomm, vroommm machines, we aren't going to be able to use them.

Yea. About $600.

My apologies. I used to have a memory like a steel trap and couldn't forget anything. Coping with this new aspect of my brain has been interesting.

Warning: Thread knot. To answer a question you asked some time ago but I didn't want to answer until I'd looked it up because I knew I'd f*** it up if I answered from memory...

m^2c^4 = sqrt( e^2 -p^2c^2)
