Did NASA build something that I don't know about?:P
Yes.:-)
On the probe they sent a couple of years ago to Halley's Comet, they used a plate of some substance dense enough but non-splintering to heat particles to a sufficient temperature to evaporate them. They mounted the plate on some rods a short distance in front of the spacecraft (front meaning here the most likely impact vector of particles), leaving some room for the debris to evaporate between the shield and the craft.
Ok, it's not a force field, but it worked long enough to get some rather nice pictures of Halley...
There are hundreds of applications on the system that are CHROOT'ed, that is have access as root when executed.
You mean setuid(root). Chroot means the root-directory of the software is changed, in effect putting it in a rather secure sandbox...
If
one of these hundreds of apps were to become infected (chances are fair to good), than you can kiss your entire system
good-bye.
No, they aren't. If the virus manages to infect one of these binaries, it already *has* root, so it can infect any other binary, too. Basically, it depends on if the virus is able to execute a local root compromise, which is easier than remote, but not *that* easy.
I think, this is not so much about tracking copies but more about control. I can see them pushing through some legislation requiring players to check for that ID and to refuse playing otherwise.
That again would mean higher barriers of entry for small manufacturers, whose discs wouldn't be playable on most consumer players.
See the german company Cargolifter, they are developing and building commercial airships for very large transport applications (ok, mostly they're still vapor ware).
Disclaimer: I'm German, so all my numbers are metric, unless otherwise said.;-)
They don't necessarily speed, they're just going very fast.
I remember an anecdote from my own driver training to get my license:
There are some compulsory parts in every driver edudation, one of them is having driven at least 2 hours on the Autobahn. Well, there I was, 8 hours into my training, on the Autobahn, doing 130 (the Richtgeschwindigkeit, some voluntary speed limit), being very careful and everything. My trainer watched me for a while, then told me, he wants to see if I can go faster without panicking or losing control or situational awareness. I told him, I'm just observing the Richtgeschwindigkeit, so the told me to go faster, up to the max. speed of the car... well, no problem, I'd just wanted to be nice... *vrooommm* voila, 170!....
IMHO it's not all that dangerous to go fast, if you know what you're doing and there are no other cars around to suddently get in your way. Hint: you can do 200+, but never, ever pass a car in the next lane with more than 50% speed difference, and even that's fucking dangerous, because there are some people who underestimate your speed and just switch lanes, there are people who just want to give you a scare for going so fast (and then underestimate your speed), and then there are the people who are just unobservant and don't look in the mirror before changing lanes...
Also, be able to stop your car within your visibility range, so if there's heavy rain or fog, slow down! There will be others that still speed, but they're the ones that get themselves killed.
The Upgrade book ist the only one you mention that has the required shelf life for a library. Imagine you borrowed an eight year old "Learning Excel" from the library and tried to use it on a current version of Excel. No Way!
Really, the only books that are good for a library are the ones that are OS and mostly version agnostic. Books in libraries tend to live on the shelves literally decades! Do you think a 20 year old copy of Knuth's TAOCP or a 20 year old copy of "Learning the MS-DOS Operating System" is better?
Remember, in this subject, we have a timeframe almost TEN TIMES as long as we're used to be dealing with!
The Cargo Lifter is not meant to be a competition for helicopters, but as a way to carry *large* cargos for long ways. The airship they are developing will be able to carry 160 tons of cargo on the long range (hundreds of kilometers and up).
One very neat trick they use is water tanks: when they go in, the ship is carrying 160 tons of water. They attach the load, then start dumping water till the load lifts off. At the destination, the load on water till the lines go slack...:-)
I think, the cargo lifter is no competition for helicopters, because they are much smaller, faster and probably cheaper to operate. However, this system is meant as a replacement for oversize road transports, because they need no roads. Also, they are much faster than road transporting, for example, a big generator! They just attach to the machine at the factory, lift off, and go either all the way to the destination or offload it onto a ship, which goes the rest of the way.
No, in their case, theme park and visitors center are important, because they don't burn money on them, they use them to *make* money. They need the money from the theme park for the development of the big ship. (They already have a smaller scale short range version in balloon shape)
Another idea is to really get going with the home appliance concept, ie communicating with your stove to make sure it's
off when your not there, checking your security system, etc. I don't know what's taking so long with these ideas, what's so
complicated about tying an on/off switch into a computer?
I don't know what's so complicated about doing that, either. But I don't think you'll be checking if your stove's off from abroad, more likely your security system will notice that you've left the house, check whether the stove is off, check the state of your bathroom, check the quality of the air (and air your rooms if necessary), check the contents of your fridge (and order supplies if necessary).
Probably the system will profile your habits a bit, get to know you, and don't rip the windows open while you're for a short chat over at the neighbor's, but while you're at the office.
The system might also get a notice from your car when you've left the office, if you're heading home or not and fire up heating, stove, water heater, aircon, etc. accordingly. Or it might notice you've booked a holiday trip and put aircon and heating in energy save mode when you've left the building.
What I'm saying here is: It's not about being able to do everything from abroad, it's about integration! All this stuff is probably bound to eat up quite some cpu cycles, as there are quite some problems to solve, like: "Is this guy supposed to be in here? Yup, he came in with the master, the master told him he could stay even when he's not in, so I'm not supposed to sound the alarm." Or: "What's that guy doing in here? I better get the boss and the police to look at him!"
What would happen? IMHO, just about nothing, at least on/.
Reporting on wars is not the purpose of/., otherwise we would have heard about the war in Chechenia (sp?), in Macedonia, in Bosnia, and probably a whole lot of other locations.
Hopefully, publications will spring up, possibly using part of the/. technology, like the moderation system, but where everyone can post, and whose threads will later be sort of expired, based on a function of total score and time online. Hopefully, nothing will be deleted in that process, just archived in a searchable way.
Also, there might be news services that use the freenet technology (http://www.freenetproject.org/) to distribute the news, while achieving some level of resistance against disaster, be it censorship or weapon effects.
Also, if you want to conserve your ammo and still want to be able to do your job, you always fire single shots. Full auto is useful for only one thing, IMHO: a heavy short-range barrage to stop an assault. (That is just my interpretation of the preference of the G3 over something like the M16 in the german army. - As a side note, apparently they are currently changing from the G3 to the G38, which is 5.56... I don't agree with that decision.)
BTW: I heard about a demonstration once, when they put a log (the kind recruits use for cover) on a shooting range, put a standard issue german steel helmet behind it (with a melon inside) and opened fire with a G3 at 250m.
One shot, one hit, one exploding log, one flying helmet with two holes in it, one destroyed melon.
That is the stopping power of the G3. I wonder if a M16 round would have penetrated that helmet, after passing through at least 20cm of wood (fir or something like that)...
I guess most of the old users have a job now (other than posting on/.;-)), so they end up having less time, at the same time reading probably at level 2+, so they just see the cream of the posts...
I, myself read/. about half an hour every day, tops, and I still try to take a look at every headline that interests me. How do you expect me to be able to keep up with all that? Right by using the scoring system of/.. (I'd like something like that for Usenet, but unfortunately that's impossible.)
Another reason for us "old farts" not to post is that we (I, that is, in this case;-)) have learned to read all the posts first, just to avoid redundancy! Most of the time someone has already posted the statement I just wanted to add, so it's pointless to post and stupid "me too!"-posts are AOL at best...;-)
I hope this clears this up a bit.:-)

I think this will not be so much of a problem, as these microsats have a rather low density/air drag ratio and are launched into a low orbit. I expect all of them to be back in the atmosphere and burned up within 5 years. Due to their small size, a whole load of them should cause about the same amount of environmental pollution as one big satellite, so even that shouldn't be too much of a problem.:-)
The G3 has a V0 of about 780 m/s, which translates to about 2340 fps. Nowhere near 10k fps, but still plenty enough. Also, the M16 reaches the same speed as the G3 (using high speed ammo), but the G3 (and the AK-47) have 7.62mm, while the M16 only has 5.56mm.:-)

What about asking one of the Gutenberg-like projects? Aren't there some projects that are tax-exempt and can do issue tax-deductible receipts (I don't know how it works in the US (I seem to recall Chapter 19 or so))?
If so, can't some lawyer donate some time to one of these projects to counsel people like IronChef on topics like that? Freeing written texts definately falls in their scope, doesn't it?;-)
Disclaimer: No, I didn't research if there isn't already such a project. I'm just rambling, so forgive me, please!;-)

AFAIK, the cable is to be deployed from a satellite in GEO. That means, one half (sub-GEO) hangs towards earth (gravitational), the other half "hangs" away from earth (centrifugal).
Ergo, the cable is under tension all the time and has no chance to develop a knot.
