My brother had a car that he had like NO idea how to take care of man. and he like filled up the oil and didn't put the cap back on and ran the car for a few days and a week later or something the car like DIED man, SO DEAD. I mean it's totatlly lame to expect my brother to know that even if the oil light goes back off there's probably still a problem. I mean cars should totally just work. You shouldn't even have to know how to drive or anything, and if you run into phone poles by accident somebody should like fix it for free or it should be made of plastic or something.
Seriously people, If you want to cruise on the info superhighway learn how to drive(get a firewall, AV, know how to work your box). If you don't know that stuff and something breaks its not MS's or Linus'es or anybody elses fault, its yours
It would be really nice if all sound cards supported some sort of legacy mode like video cards. When I boot my computer stuff shows up on the screen. With graphics and stuff too. The Bios didn't come with thre right driver, all video cards just work if you talk to them right.
Most have other cool modes you can switch them into later if you do have the driver but I really think there should have been a sound card standard like the video standard so that you would always have some basic sound support.
I'm not really in the biz either but I get the impression that if you are writing code for the DoD you either write it yourself or licence pre-certified code. That way you audit your code and the pre-certified stuff you can pass the buck on to that company?
If you had to take an OS no one at your company had taken part in writing and justify every line of code to uptight auditors(actually required for some projects AFIK) it would probably cost you more than writing it over again yourself.
None of this is authoritative it's just the impression I've gotten from companies and proffesors I've worked with that in turn did some DoD stuff.
My wife and I live in a smallish two beddrom apartment with no air conditioning, gas heat and a gas water heater. We use compact flourecent bulbs whenever possible.
Our electrical bills are about $20 per month. At the going rate of $.0069 per kilowatt hour we use about 300/month. that averages to a 400Watt continuing usage.
Yes but the other people you would donate that computer to need one whether you give yours to them or not. If you keep yours around it wastes energy as well as the one poor school districts STILL have to buy.
Analog can actually reproduce sound better than digital equipment can.
In theory if you sample higher than the Nyquist frequency(double the maximum frequency you want to reproduce) then you can reproduce perfectly the original signal.
That unfortunatly assumes that you use an infinite number of bits to encode each sample eliminating quanitization error, and that you have perfect DACs on you playback hardware.
Neither of these features are currently available on commercial equipment and "rumor has it" that the error introduced by high end digital audio stuff is higher than the error introduced in analog stuff.
And the analog stuff sounds better. It just costs a lot more.
What I would really like to see are hydrogen generator hybrid cars.
I forsee cars with a hydrogen generator(fuel cell if they ever get efficient enough) some super capacitors for hard acceleration and for holding regeneritive braking and a motor on each wheel
The generator provides more than the average amount of power needed. Since you never dump carbon based stuff in it you'll never worry about valves clogging up and you get zero pollution.
The super capacitors are really cool. I've seen a modified EV1 running off just a capacitor bank that gets through the 1/4 mile in under 16 seconds with juice to spare. And since you can charge them as fast as your wires will take the current your regenerative braking will be much more efficient.
The motors on each wheel mean you lose no power in drive trains and get true all wheel drive all the time.
Batteries have such low energy density compared to any kind of combustible chemical it is laughable. The only advantage batteries have over fossil fuels is their lack of polution. Hydrogen solves both probems. It has about 1/4 the energy per volume as a liquid so your gas tank will have to go from 12 gallons(my civic) to 48. Thats a big jump but not as bad as batteries would be. Hydrogen isn't that bad, long range and no expensive batteries or fuel cells(if you burn it in a normal combustion engine) and zero pollution(except heat and steam). And since we can't produce gasoline or methonal ethanol, diesel etc from arbitrary energy sources this sounds pretty good to me. All the choices you list except biodiesel demand that we remain dependent on foreign oil or start mining more of our own. Niether is something I'm really excited about

True but by some accounts it did so only using 2 pounds of hydrogen for fuel. I wish my car were so adept at using fuel for acceleration:>
That will depend on how ipv6 addresses are allocate. IPv6 pushes address space from 32 bits(~4 billion) to 128 bits (~4billion^4) if everyone spread out over the whole range it could slow down the spread of viruses since each random address would have a much lower chance of hitting a live machine. If however we all cluster in the same part of that range it won't help at all.
I actually think it's a little more complicated than that. It is true that the risk factors have not changed but we have gained a new understanding of what they really are. We'd really like to believe that NASA has good estimates of what the real risk factors are but I'd wager they're guessing just as much as their engineers as to what the failure rates for the hundreds or thousands of systems on the shuttle are.
Nasa doesn't quite have the auto industries aqtuarial tables to go off of so when a second shuttle blows up it effectivly doubles the KNOWN risk factor for manned space flight. Up till then we were guessing that it was less dangerous than it really was.
but last time I checked there are lots of open source projects that run on windows as well as linux. And there are lots of closed source applications that run on linux.
So if the new 2.6 kernel happens to break the linux versions of ProE or Gaussian 98 or Verilog are Slashdoters going to complain the same way that Linus is evil and irresponsible?
Yeah... Us Republicans usually like to have a lot of debt in the government, especially if it means we can maintain a huge welfare state, subsidize stuff and mess with the economy in any other artificial way.
Dems are usually the ones uniterested in how much public services cost. I am a republican and I don't really like Bush's economic policy but he will get my vote because I actually believe he does whatever he thinks is right(haven't seen that in my lifetime). Even if it means crossing party lines the way his economic policy has.
I think you are forgetting a major problem with arcologies. People don't want to live in them. If they did there would be a big expensive one in Aspen Colorado where all the rich people go on vacation.
I agree with you on all technical, environmental, and economical points but you will have a very hard time convincing people to give up their yards and cars and shrubbery and sunlight all day long to live in what they will inevitably percieve as a large box
I think the problem with this is that it is non directional.
If I detect a missle coming my way and set off an emp to kill it my emp system, watch, radar, and everything else in the neighborhood is dead.
So the obvious solution from the attackers view is to send another missle right after the first. Since the radar and emp are dead they can't defend themselves this time
As you said, it would be a good last ditch defense against a missle if you had no other choice but It wouldn't be that great since all the technology you and your buddies were lugging around would now be really neat looking paperweights
Can't swear to it but I have heard here on slashdot from others that Green destiny sits in one rack and requires no special climate control. Since these morph x86 code and retain that translation they are very efficient when they run the same loops over and over as in scientific computing
but recently I've started getting spam that looks like
<conspiracy theory> secret messages. They have wierd almost white words like moon, apocalypse, and kansas after large bold titles. </conspiracy theory>

Oddly enough they tend to be the ones about keeping spam out of my email box.
It sounds like you may be able to spray it on and cure it in situ. I couldn't swear to it but I'm guessing you could just spray the shuttle, wait for it to "set up" and then flame throwerize the whole thing

They called it sonolumenecense or something like that. It didn't produce fusion at the time but they thought it might be a possibility
Good to know some cool wacky experiments come to fruition.

It is very possible that the NSA or similar organization would "certify" a distro for its ability to keep information from prying eyes.
That is not the same as certifying that something will not ever miss a real time deadline.

the whole point of the 50 feet thing was that when the reciever STOPS reciveing the signal your transmiter puts out it blows unless disamred
I'm guessing anyway. Extra noise wouldn't matter.
