I thought they pushed -- opposite and equal reaction and all that
They blow.
Reminds me of the woman at HP Germany where I gave a training many years ago. When we talked about a cooling fan, she asked: "Does it suck or blow?" Yes I was able to control my face, but it was hard.
Yes, stiction isn't about the Casimir force. Any two very smooth and very planar surfaces will stick together when they come so close that no more air molecules bounce around between them. In vacuum, metals will even weld together at low temperatures. That's a major problem in spaceflight. Stiction just means that the force to overcome the static friction (sticking together) is way higher than the normal, dynamic friction. I've seen disk heads ripped off by stiction:)
The same could be said for countries as a whole. One would expect to find a greater proportion of scientists in an industrialized country over an agrarian one, or over a nation that has only recently industrialized.
Or that has over 50% people with a nonscientific worldview?
Maybe you can find a few Bigfoot on eBay:) That was too much of a niche market and the access times were truly horrible. Today nobody even makes 5.25" platters any more.
Power goes up with the square of rpm. That's why 15k drives have 3" platters - otherwise they'd burn too much power. Also, it's pretty hard to accelerate the heads any faster than they do now - it would required stronger actuator magnets which would be too costly. Also you'd have to devote more surface area to servo bursts so the heads know where they are during those very short seeks. That would cost capacity. There's a tendency towards 2.5" drives for high performance. 3.5" is becoming the new 5.25".
Of course since nobody will want to stuff all of Perl + half of CPAN down the pipe every time an applet loads
Why not? It'll be cached in the browser and startup can't take much longer than revving up a JVM or downloading all the JS and Flash scripts that today's sites need.
If there's a fine-enough-grained package management we can have lots of goodness out of this.
Cool! Finally I can build a tree of tabs, not just a linear list. Just what I needed to get lost completely. Now I want a VM running in a tab, or at least a separate process with its own window. And a Gecko ActiveX plugin so we can show IE users how to browse properly.
It's the same as saying "my car runs on electricity, it's completely pollution free and carbon neutral!"
Hydrogen is not a fuel. It's a way of storing and transporting energy. That energy has to come from somewhere - generally fossil or nuclear fueled power plants. Free hydrogen does not naturally exist on earth, it has to be manufactured, stored and transported at enormous cost in energy. The overall efficiency is crap.
Yes, but for how long have American consumers been brainwashed by "bigger=heavier=safer=better" marketing from Detroit so they can sell their cheap and primitive heavy trucks and SUVs? To the extent that even European and Japanese manufacturers started making those SUV abominations for the US market.
If you look at the comments below TFA, about half of them (and many here - I thought this is "news for nerds", not "news for the unwashed masses") are "it's a death trap, such a small/light car can't be safe." Bzzzt, wrong. The comparison with F1/Indy cars is 100% correct, and it's about time that this kind of tech gets on the roads. If you can walk away from hitting a concrete barrier at 100+ mph, you'll walk away from a head-on collision with an SUV too.
This whole many core hype looks a lot like the Gigahertz craze from a few years ago. Obviously they're afraid that there will be no reason to upgrade. 2 or 4 cores, ok - you often (sometimes?) have that many tasks active. But significantly more will only buy you throughput for games, simulations and similar heavy computations. Unless we (IAACS too) rewrite all of our apps under new paradigms like functional programming (e.g. in Erlang.) Which will only be done if there's a good reason for it.
Actually insightful. If there was built-in P2P functionality, this wouldn't happen. Hash the URL, keep a list of neighbors, and ask them if they have the page. If necessary use a DHT.
That's being easy on FF. With Linky, you can select a range of links and open them all at once in tabs. Open 100 tabs? No problem. I have yet to see a crash doing that. Linky works well in FF 3.0 with compatibility checking off; it hasn't been updated to a 3.0 compatible version alas.
The honorable thing to do in that situation would have been to resign immediately. Either he did what he was told by his boss, against his conscience, or he lied consciously, or he was duped. Neither looks good on his resume.
Why was this modded Flamebait? While Powell has a pretty good reputation in the US, in the rest of the world he seems largely discredited after the WMD fiasco.

The main problem is: chemical rockets suck.

No computing based on nano diamond rods? Meh.

More than you'd ever want to know about this - a seminar by Mark Kryder at CMU:

If you have C then you have C++ too.
No need to use the old libraries.
Meh.
But we can have Perl running in the browser, finally.

Yeah. And of course, because I can now watch CNN in HD, I have absolutely no desire to read or watch any news at all online.
Why would you want to watch *news* when you can be *entertained* by watching CNN - now in HD!
News is so depressing.

That clearly shows how bad their Internet infrastructure is compared to the US, where we have *unlimited* accounts!

Yup. Its Amdahl's law.

Too heavy for me.
I stopped at "We can also split apples (and dollars) into smaller pieces, like half an apple, or a hundredth of a dollar."
They're not down, they just had to disable a number of torrents.
The site seem to be slightly slashdotted though.
Guess what ideal webbrowser and ideal hookers have in common.
Free-as-in-beer?

That's too bare bones. I use a fancy version:
wget -O - http://www.google.com/ | less
Corollary: Revamp the plugin architecture so that plugins have to run in a separate process.
