So how will this fuelless baby get into the air? I suspect once it becomes lighter than air, that getting into the air will not be a problem. The problem is that continuously changing the buoyancy would most likely consume far more energy then simply pushing a dirigible along with a prop. Compressors are notoriously innefficient due to turbulent air (or other gas) flow.
you have potentially billions or trillions of combinations depending on how the lock is made not with only 6 inputs. My point was that the number of combinations is equal to the factorial of the number of inputs. So with 16 inputs, yes you would have 20,922,789,888,000 different combinations. But 6 inputs only gives you 720 different combinations, which is not enough IMHO.
Fiber optics don't wear out in the same way as electrical contacts. Furthermore, locks tend to be on the outside of doors, making them susceptible to moisture. Moisture is usually considered a very bad thing around electric circuits. However, couldn't you do the same thing by sending different pneumatic air pulse patterns down 6 different pipes?
Well, no. They obviously send a unique pulse pattern down each fiber, otherwise they could not determine which was routed where. So while you could proably disable the photocells by flooding them with light, you couldn't get them to register the correct pattern.
With 6 optical fibers, aren't there only 6! or 720 possible different "routing patterns"? How hard would it be to construct an electro-optical devices that would simply run through all 720 patterns until one worked? And no, you can't disable the device for a fixed time when it gets a misroute, because it is obviously going to misroute while someone is inserting the key... and someone like me who has two almost identical keys on their keychain is going to get really pissed off when they insert the wrong one. Finally... haven't we learned by now that replacing a simple mechanical device with an electro-optical-mechanical device greatly increases your failure modes?
Although I'm sure there are technological measures that could facilitate sharing, I'm willing to bet they all depend on all participants being well behaved. For example, the Ethernet CDMA algorithm relies on random exponential backoff in response to collisions. One node could theoretically increase its own throughput on a saturated subnet by ignoring the algrithm and immediately retransmitting instead. This would work until everybody started doing it, at which point effective throughput drops to zero. How do "software radios" guarantee that they will still abide by the rules established by the FCC for sharing?
"Essentially limitless bandwidth" is a misleading expression; I beleive the best that you can do is to design a system where throughput under heavy use degrades in a way that is fair to all participants.
our major problem will be that bandwidth is now treated in the world also as a product, rather than a public utility. And you are allowed to have, in general, as much bandwidth as you can pay for. So then in the world in which we now exist, though hardware is cheap and software is free, there are major difficulties in disseminating knowledge and encouraging the diffusion of science and the useful arts, because people are too poor to pay for the bandwidth that they require in order to learn.
Bandwidth is effectively a "commons". As such, unless there is some economic disincentive to prevent every user from utilizing just as much bandwidth as they can, it is subject to the problem of "The Tragedy of the Commons." Surely Professor Moglen doesn't beleive bandwidth can long continue to violate the basic principles of economics...
Unfortunately, the Samba team has already declared that they are taking the moral high road on this, and will continue to let SCO use Samba -- even if they are being asses.
If you were to throw a black cape and a tall hat on him, he could be a circus magician. Now, if you but a black cape and stovepipe hat on him, he'd look exactly like Snidely Whiplash
Does this remind anybody else of the old Saturday Night Live routine where Gavin Morris translated everything Chevy Chase said "for the hearing impaired" by just shouting the same phrase out loudly?
I bet this guy is really a chick magnet! Isn't breaking a Nintendo record really just nature's way of telling you that you really, really, REALLY need to get a life?
When you make a mistake and break something, hey, there's a good chance you won't make that *exact* mistake again. How true. I was trying to build my own modem once and fried the breadboard. I've stuck to writing software ever since!
What in their business model suggested to them "You know, we could make a LOT more money delivering music online if me spend company funds to buy a Harley and a Hummer!"
During Rosetta's rendezvous with the comet, commands from Earth will take about 50 minutes to reach the spacecraft. So the probe has been designed with a degree of autonomy, allowing it to think for itself. Couldn't this come back to haunt us, or have I been watching too much Sci-Fi? You know, if it could really think for itself, Rosetta would be telling us "You want me to do WHAT?!? Are you out of your mind?!?"
I used to be a Guinness drinker, but the dark/heavy drinks became a little too much for me - especially when you're trying to have a meal with your drink. I thought that in Ireland, having a Guiness was considered a meal...

electrical connections can jingle jangle in your pocket all day long and still be functional.
Until they corrode. You've obviously never lived near the ocean.

At least on my microwave, these two are exactly the same time... was the transcriber using some timebase not comprised of 60-minute hours?

Next time, would you please start with 4 nodes, just to make us anal retentive computer geeks happy? Thanks.
Better yet, ask anyone who used to work there... anybody still working there is under strict instructions not to reveal Ellison's true identity...

He who breaks a thing to find out what it is, has left the path of wisdom. Could you please explain that to my 3-year old? Thanks.
Why not 16 nodes, or some other power of 2?
Never release any patches, and there will never be any exploits! Isn't that the strategy M$ is already following?
And she doesn't order one for you too? I'd get a new girlfriend!

Now, instead of harsher measures, we can talk a comet out of hitting us... Or threaten it with regime change if it doesn't change it's course...
