You could do even better by putting a good part of the maglev track in a vacuum.
[ . . . ] The trick would be the transition zone though. Maybe an airlock that's programmed to open at the correct time?
I've thought about this before. How about you pump the launch tube out to a dirty vacuum and cap it with a frangible plastic cap laced with explosives?
You detonate the explosive charge just before the capsule reaches the cap and the pressure bow wave pushes the shattered pieces out of the way.
Maybe the NYT article doesn't mention centralized login because such an obviously bad idea?
. . . if there's only one password to remember the likelihood of it being written down, exactly the same as the username or otherwise trivially guessable probably drops dramatically.
Schneier recommends that passwords should be written down but kept in a safe place, such as a wallet.
Now, if something like OpenID were to support certificate-based authentication...
Yes, good idea, but password managers and password generators provide the same sort of functionality as a centralized log-in system, without having to trust a third party. On Windows I use the PasswordMaker add-on for Firefox plus Keepass as my password manager. PasswordMaker also has a stand alone desktop version.
But the fact that actual IQ score samples form a symmetric bell curve centered on 100 does.
Actually the IQ distribution does not perfectly match the bell curve; there is a bulge at the lower end. They're not sure why, but it may have something to do with problems at time of birth.
I've often thought we should establish a standard where the keyboard of a desktop computer can be used as a smart terminal when doing secure transactions.
The keyboard manufacturers such as Logitech and Microsoft would build the basic carcass to match a standard and the regulatory authority would provide a secure plug-in encrypting module. When you flip a switch the the keyboard would turn into a smart terminal with a small LCD screen and the main computer would be relegated to a communications device.
Key loggers would be SOL and if you provide the right transaction information, displayed on the inbuilt LCD screen, you could make it difficult for "Man in the middle" attacks
One possible difficulty in, say, hiding messages in low-weight bits ("noise") of digital pictures that I recently thought of (combination of my work and reading that particular thread you referenced) is that they are produced by a physical object (digital camera sensor), with noise likely to Boltzmann-distributed at, say, 300K. If a program sees just white noise there, or some much higher or much lower effective T, well, immediate red flag!
Now, it is probably possible to take effects like this into account when designing your program, but it would take someone well-versed both in math of crypto AND physics of sensors, which is obviously somewhat higher threshold, and it might end up not being "universal" for different image sources.
That may apply to the RAW photo but I wonder how much of that is left after the photo has been converted to JPEG, contrast adjusted, unsharp masked, resized etc?
The paywall proper has only been in effect a few weeks, maybe better marketing and a better price point (I think £1 a day is too much for digitally delivered content, especially if the actual print edition is the same price!).
An interesting piece by David Mitchell at the Guardian as to why he would like to see this succeed is worth a read.
A comment to the Guardian piece by "Scurra" sums it up for me:
(Extract) "The drawback is the part about paying for everything else that I don't want. That's the "piracy" argument in a nutshell. There's good evidence that a lot of things that that are downloaded "illegally" are not "lost sales" because the downloader often ends up not wanting whatever it is. But it also tends to show that if they do want it, they often go out and pay money for it properly.
Now I agree that part of the problem is that somehow you need to find and then build an audience - but once you've found them, they are generally willing to pay. It's just that finding the best way to pay is proving extremely elusive in the world of "print" media when translated online.
Although as the piece notes, charging even a nominal fee tends to persuade people to value something. As a result, "micropayments" may indeed be a possibility, except that no-one seems to have figured out how to square this with possible privacy issues (since it's far more risky than flat credit card payments because of the sheer volume involved.) "
A system like this shouldn't have too much trouble identifying pedestrian "walk/don't walk" traffic signals and giving an audio signal when they turn red or green..
As others have noted, already done in Australia, Europe etc.
I've wondered if they could put micro-powered FM transmitters in every traffic light to announce what's going on. They could have a different broadcast frequency for each direction of crossing, and the custom FM receivers would change channel depending on compass bearing. With modern electronics I think this could be done very cheaply.
How much does one unit cost, and is this actually scalable and affordable for nations where there are landmines? Most of these countries are third-world as the majority of landmines in first-world countries (e.g. Germany) was cleared years ago.
This would be more likely used in actual combat, to breach a protective minefield prior to an assault.
I'm thinking of setting up a service where people send me all their paper money ($20 notes and up), and I check to see if they're counterfeit or not. If any notes are counterfeit I destroy them so that my clients won't get into trouble by passing dud notes.
another problem with a highly faceted desing is going to be in making the nominally circular cells conform to odd shaped facets, and for mass producing these.
That's because nobody has thought to slice the silicon ingots _lengthwise_ which would yield long (although varying width) rectangular strips, which could be cut into square or rectangular shapes which would fit more densely into square panels.
There are frequent slashdot postings saying that anti-virus programs are a waste of time.
Maybe this is one example of why it might be a good idea to have one available for an occasional scan. Admittedly anyone running a *nix based computer would not have had a problem with this malware.
"What kind of speeds can I expect?
Over the 3G network, download speeds average from 400kbps-800kbps. Upload ranges from 128kbps-300kbps. When not on 3G the average download is 120kbps-200kbps and 50kbps-100kbps for upload."q>
Now we know why the kids are so quiet. They spend the whole trip waiting for something to load.
Many control features already exist on the stock Audi. For example, the computers in Shelley's trunk will plug into the car's existing electric steering system. The car moves into action with stock automatic gear shifting and brakes with an active vacuum booster, a feature that normal cars use for emergency braking.
Briefly they cut thick wafers from the boule (typically 1mm to 2mm) then mill vertically into the the
wafer. They turn the cut sliver side-on and process it into a conventional solar cell then glue multiple
slivers into panels. Each sliver is only 20 to 50 microns thick.
Many of the "inane" questions in the article illustrate the stupidity of the journalist who wrote the article. Most of these questions are legitimate, with a legitimate answer.
Can you drink your own urine?
Again, a legitimate question. In a desperate situation, drinking your own urine may extend your survival under some environmental conditions. It's commonly mentioned in media.
Also, I believe drinking your own urine is advocated by some weird alternative medicine and religious practices.
One point that has been little mentioned in these posts... Why the hell do these companies have classified information accessible from public facing networks? This kind of information should be available on internal networks only.

Whoosh!
(that's the sound the craft would make going by overhead, nothing like the sound of his humor sneaking by you disguised as facetiousness..)
At Mach 10 it'd be more of a Bang! than a Whoosh!, probably taking out your windows in the process.
I care if he watches porn if he then votes for internet pornography filters. I can't stand hypocrites.
Note that I don't know if this is the case, but it wouldn't surprise me at all.

What do you think? Does this have possibilities?
A standard horsepower is less than 0.75kW, so for a cow to be producing 2kW they would have to be using whips!
I suspect this is a left-over April fools article

Already been done: see www.sliver.com.au.
If only the GAO had thought to hold back the report a few more days, they could have released it on April 1.

Huh? Does this mean Audis are "Steer by Wire"?
All three of the browsers on my system (Firefox 3.6, Opera 10.x and IE8) show as unique, and I do have Noscript enabled on Firefox.

As a nurse I would welcome this as I have to wash and disinfect my hands several times a day.
Only several? That's disturbing. I'd have thought you'd have to wash them after every patient contact.
