Actually, Paris-Lyon is short-distance enough that a TGV does make sense, because I believe it takes about 2.5 hours nowadays to
travel that distance by TGV.
2 hours, give or take 10 min. That's definitely faster than flying, esp. if you consider boarding time ends about ten seconds before departure, and train stations are right in the city centers.
Paris-Marseille should be 3.5 hours. Oh, and Paris-London is 3 hours if you're interested. Flights probably took less of a hit there, as many people connect at Heathrow or Roissy (both are major hubs).
It could make short-distance air travel obselete on any
corridor where the maglev train is running.
That's what it did in France : air traffic between Paris and Lyon has been almost killed by the TGV, and companies flying Paris-Marseille are expecting a major loss starting next summer, when the high-speed line extension is completed.
Actually, i just recently read about a study saying that a MagLev (TransRapid) connection between Amsterdam and Groningen (in the
most northeastern part of the Netherlands) would be quite viable. I would certainly be nice if such a connection would be made (it takes
something like 4 hours now for the 250-300 km)
Though it would be a loss of connectivity... TGVs already go up to Amsterdam, it could be smarter to build a high-speed line that allows going south to Belgium and France (and west to London!) instead of switching trains at Amsterdam.
Trains and planes both have very efficient engines
Electric trains have much more efficient engines than planes. Jet engines are forced to incur a heat->work conversion, while electric motors generate movement directly with electromagnets (just a bit of electrical resistivity here, doesn't waste much power).
You don't need transistors for that. There are some conductive films that can darken when current passes through. I have seen that in a lab: a window with a dimmer switch to obscure it. I believe it is already industriailzed, though still expensive.
you can now buy ASICs with hardware protection and encrypted digital links. you can also get tamper proof devices all the way from antenna to decoder to screen...
If they don't allow US corporations the right to sell those hi-res photos, someone in another country will jump on the opportunity. E.g. Spot Image, in France. IIRC, they're planning a sub-meter satellite somewhere in the next decade.
By the way, a little known fact is that American submarines rely in a large part on French sonar technology. This should make the nukes somewhat more unpredictable...
Ford doesn't put a logo on its trucks to advertise Ford to the owner of the truck. The Netscape situation is more like the following:
Ceiling of truck covered with unremovable maps directing you to all the Ford owned places you can drive to, but nothing else
Truck asks you if you would like it to be your 'default vehicle' and changes all your car keys to only work in this truck
Low Gas light reminding you to buy some more Ford gas
Big sign behind the spare tire slot reminding you to buy another Ford tire
I could put up with this if Ford gave me a free car... remember: Netscape's browser is FREE.
How exactly is a UMTS device different to a cell-phone?
In a sense it's a cell phone, however it's designed to work in packet mode with a massive bandwidth (up to 2Mbit/s). Since those phones are due about 2 years from now they'll probably be more like pocket-multimedia-internet-devices than cell-phones.
This looks like a good idea indeed... trouble is, the first field tests have shown that dogs get mad at these little turbines. This is no joke, they actually can't bear their ultrasonic whine.
like PGPDisk, and find it useful for large numbers of files. And really, it's the only option for my chosen platform (Macs)
It's not the only option. If you look around you can still find CryptDisk (go for version 1.2.1). It's somewhat old, though very reliable. AFAIK, Will Price, the author, has been hired to write PGPdisk for Mac.
Besides (still AFAIK) both CryptDisk and the PGPdisk version included with 6.0.2i suffer from the same problem: they are incompatible with MacOS 9. Alas this is the sole version of PGPdisk that was "mistakenly included" in PGP freeware...
One security weakness I see is that an attacker can keep track of the pad database, keeping a note of the dates all pads are added to the database.
David thought of this. If you read the article carefully, you'll see it says: "Pads should be mirrored as much as possible around the Internet. However, no single site should ever mirror all the pads -- nor a too large fraction of them. "
Another thing : I just did some quick math... it seems a plane at cruise speed is just too fast. Doppler would shift the frequency off the channel (at least with TDMAs, like GSM; I don't know for CDMAs) around 500-700 km/h (300-400 mph).
OTOH it works fine in a high-speed train (300 km/h).
We have a laser beam over a street here (albeit an old one; 5-10 yr old, around 1-2 Mbit/s, IIRC). Flying pigeons are no trouble (well, it bogs down NFS, that's all)... and pigeons just won't land on the nailboards laid under the laser boxes.
Overall, works well and reliably. The only problem is with heavy rain.
Software, porting, performance...

"will this mean no Linux/Mac/BSD/Be et al. support?"
Even as closed-source software we'll hardly see anything coming out for these. AFAIK, the only software modem ever for the Mac was Apple's own work.
Well... this means my built-in modem does work with LinuxPPC:-)
Of course, I'd really like to see us use miniature gas-turbine engines, but I don't expect to see this anytime soon...
Actually I remeber talking with a Renault engineer... they did experiment with those tiny gas-turbines a couple years ago. Problems were temperature (though ceramics could handle it), and ultrasonic hiss. Dogs went mad at it even a kilometer away...
Now they've dropped that technology, focusing instead on fuel-cells.

On this subject an interesting (though somewhat OT) link: Design Principles for Tamper-Resistant Smartcard Processors with a lot of info on how to, well, hack hardware.
This sounds exactly like the startup sequence of MacOS X: progress bar plus a couple messages ("starting portmapper", etc.)

Probably Israel, and almost certainly India.
I think most of Western Europe would launch this sort of satellite on Ariane. IIRC, Germany has one (or more?) orbiting already.
This is not intended as a troll. This is a quite serious answer.

This is NOT the government. This is a judge.
Now, try and tell me no American judge has ever blurted out a completely stupid and ridiculous judgment.
Heh.

No wonder he's happy to think in his 10x10 brain.
Is there such a thing as sincere trolling ?

Nice try... what about, say, people @aol.com ?
On a purely technical side, Apple has written an introduction for Windows programmers.
David thought of this. If you read the article carefully, you'll see it says: "Pads should be mirrored as much as possible around the Internet. However, no single site should ever mirror all the pads -- nor a too large fraction of them. "
So there is no "pad database" per se.
