>Do you realize how stupid that sounds? It beats the alternative. I saw several designs from that era fail for exactly that reason. A little extra spacing would add less than 1ns to the timing. Clock speeds at the time were ~16MHz = ~62ns. A stronger buffer would improve timing by more than 1ns on traces with a large RC delay into an array of 8-16 drams, by increasing the edge rates. If the design was so close to the edge that 1 ns difference broke it, it did not have sufficient margin.
No it doesn't. Ram cache doesn't give you the boot time benefit of a non volatile cache. It would still be better if that was hanging of a direct memory bus to the processor, rather than on the other side of a SATA interface. SSDs are only fast compared to rotating disks.
But address bus loading was a problem on the drams you could get in the early 80s. He should have recommended extra buffering if they were so close to the edge that a little extra spacing would break it.
The cache, whether it's flash or ram should be 'close to' the processor that benefits from rapid access to the medium. Putting the cache on the other side of the interface always was and still is stupid. We don't need SSHDs. We need motherboard makers to stick flash close to the processor (in terms of access latency and throughput) on the motherboard.
I got the clear impression from the news report (I think it was an ABC thing I clicked on) was that it was all at the capitol building. But they were throwing around 'capitol' and 'capitol building' loosely.
That's what you get for doing your day job rather than meticulously researching a topic before commenting.
Yup. I've been through this with 2 children (one my own, one grandchild). The age at which they start comprehending technology is 4. The age by which they've got it down is 5.
Jean Piaget was completely wrong on child cognitive development and these simple observations are just one of many ways to prove it.
The kids have smart phones. They don't need a locked down ishiny.
They should do what managers of open access systems have always done - Assume that the used system is dirty and image the computer back to default at suitable times.
>How long do you think it would take for a parent of a failing student who didnt have an iPad/laptop to sue the school for unfair treatment. How does the school defend against that?
So as long as you can think of something that 'might' go wrong, you can avoid doing things well. Victory!
>Well, at least the kids are learning something from their iPads, though it's not the lessons the schools intended.
Back in the day I spent my pre-teens breaking the copy protection on Apple 2 games. Probably not what my parents had in mind, but it was excellent technical training and now I have a well paid career designing chips, crypto systems and related things.
Breaking into security systems is a superbly educational thing to do. It requires a depth of understanding of the systems not commonly found in text books, it requires analytical thinking and the lessons learned often stick. If you spent your teens doing that, then the low level subjects they teach in school are not going to feel like a major challenge.
The only nun I ever knew had been enjoying the services of a priest for a long time. She quit the profession eventually. I don't think the analogy holds too well.
There's sex and drugs and crime everywhere on the internets.
Don't try to protect your children from all the evil out there. They're going to find it sooner or later. Teach your children judgement. They'll be needing it.

You don't have to run Linux on it. There are any number of OSs that can run on an x86.

So no. It doesn't sound stupid.
Yes. PCIe flash is good juju.

>Your argument makes more sense for RAM cache
No it doesn't. Ram cache doesn't give you the boot time benefit of a non volatile cache. It would still be better if that was hanging of a direct memory bus to the processor, rather than on the other side of a SATA interface. SSDs are only fast compared to rotating disks.
>The horrible evils of that war are too numerous to mention, it goes without saying,
But you said it anyway.
But address bus loading was a problem on the drams you could get in the early 80s. He should have recommended extra buffering if they were so close to the edge that a little extra spacing would break it.

Perhaps she should have tried the white house instead.

I lost against the medium AI last night. So incompetence trumps controller.
Stop being factual. I was trying to make a point.
Starcraft 2 would be pretty unplayable without a keyboard and mouse.
Maybe that's why it isn't on Steam.
Does the new Gnome have a FVWM mode, so I can use it without going postal?
This is Fairbanks.
I am.

I'm not so sure that analogy means what you think it means.
I think he meant to say "tighter than a gnat's chuff", but got lost halfway through the sentence.
