My athlon is about 1cm x 1cm (the chip part, not the package)
Vacuum does not conduct well
Semiconductor manufacturers have very precise fabrication methods
Given that, I'm sure they could figgure out a way to make the distance between any two points on two wafers 1cm2 less than 0.5cm., say by making the interconnects gold studs a micron or so high all over the surface of the wafer, and aligning them face-to-face.
the distance the information would have to travel when going trough the "vertical interconnects" would be thousands or tens of thousands bigger than the distance of any on-chip interconnection.
But also thousands or hundreds of thousands of times smaller than going outside the package; which would make it ideal for multi-processors, array processors, or large local caches.
2. There are FAR fewer than 1000 people here and FAR fewer sponsors than I was led to believe. No major discussion (some disappointment and some worry though) about HP pulling out of the Keynote...for everyone that made mention of the pull-out, 10 reminded them of who sponsored the little reception last night (HP). That was little comfort, since HP did a MUCH better job at LinuxTAG and LinuxWorld. No mention at all or concern about Intel (which I found to be, potentially, far more damaging to the attendees.).
8. VERY few, if any, Europeans or Middle Easterners. No reaction to the defeat today in India, or the greater defeat last week in China. No Australian or New Zealand accents heard. The only French accents I heard were Creole (Louisiana) and French-Canadian. High concentration of attendees from Florida and California/Arizona and some from the Midwest. Pitiful turnout compared to last year of real VARs or potential customers and REALLY bad Vendor area.
11. There ARE a few clueful participants here that are preparing to or have been convinced by the show today to drop SCO. They are tired of the impact on their businesses and they see real advantages in moving on without SCO. The many cheerleaders have not convinced them to stay. The many defections evident this year are worrying. The no-shows are worrying. Armed, uniformed guards in the show areas do not signal a healthy environment to them. Most of all, they see the products falling further and further behind, while the company continues to concentrate on this ridiculous lawsuit.
ok, once again.... the V1 was a missile propelled by a jet engine, not a rocket. A rocket carries it's own oxidizer with it. The V2 was a missile propelled by a rocket.
Neither was the first successfull guided missile, and the V2 was not the first successfull Liquid-Fueled Rocket. The germans had wire-guided air-launched anti-ship missiles before either.
X11 is allowed semi-direct access to hardware, which is why it can crash the whole OS.
Can you think of a way to access hardware without accessing hardware? I can't. Doesn't matter if it's windows, X, or SVGALib, it needs access to the hardware to set up video modes. After that, it might be able to get away with just an mmapped region of the video card.
I've never seen X crash the whole OS, by the way, but I soppose it's possible.
It's a simple fact of life that you can't shovel data around as quickly from user-space.
To architect an OS otherwise would take such a huge performance hit to make the OS unusable.
I suggest reading

In fact Linux and windows could both do some things better WRT driver isolation (like useing more than 2 rings), but it would make the kernel x86-specific in a big way.
Check the year on that used car guide. late 80's/early 90's are considered shitboxes, they don't recommend older because they don't review older cars of any manufacturer. Find an older Used Car Guide, and it'll probably say the 82-87 tercel is a recommended buy.
It seems the Tercel gets an average rating. not deathtrap.

Airbags weren't available yet in 1983.
In places where they don't put salt on the roads (like where I live) It's by no means a fluke for an 80's asian small car to still be on the road. It is a fluke for an early 90's car to still be on the road. Or even a mid-90's american car.
With modern re-inforcement, controlled crumpling, and restraints (including air bags), small cars could be made way safer than they were in the early 80's, without making them way bigger. I still wouldn't put my kids in the back of a chevy sprint though.
I bet there's a lot of delivery fleet managers who turn over a lot of cars quickly who're thinking do I really need power locks, power windows, rear spoiler, neon lights, chromed door handles, heated seats, power seats, etc. If a company can lock up that market, any sales to individual owners would just be the icing on the cake.
The whole car was everything nescesary to be an economy car; with nothing extra. Inexpensive, reliable and efficient, and not austentatious. Mine had 380,000km before it was retired.
Over the past couple of decades "economy" cars have gotten bigger and bigger, and with more and more powerfull engines and bigger price tags. Why does an economy car need 120Hp and sport styling? If they just spent the money on making it more reliable and efficient, there would be much greater improvement.
And they could market a Fleet model with maintenance services at higher price to up the margin.
the point is simple, in order to do real damage to unix you need to have root access, thats typically another step in the penetration of the system. that one step can make a big difference.
It'd really suck if all my homedir &/var/spool/mail/`whoami` got deleted, corrupted, or forwarded.
same goes for trojaning my.xinitrc or adding entries to my.forward .

2kbps! bah! and I'm on cable.
Some observations:

chips are inherently multilayer. I'm talking about stacking the wafers, not just the doping.
perhaps stacked wafers with vertical interconnects might help... I'm not sure how you'd dissipate the heat, though.
Why is this not a front page story? Laws do have a tendency to spread, you know.

My point exactly.
nope. It doesn't cary it's own oxidizer.
Like since 1941. (V1)
most of them probably won't make it across the english channel.

It has nothing to do with the article.
