After reading the FAQ by this company, I still can't see how this is going to work. Let's do some physics, shall we. Maybe someone will enlighten me.
The elevator *and all of it's parts* are to be in geostationary orbit. So, figure out what speed is required to keep something in orbit around the Earth at distance r from its center.
m_E : mass of earth m_e : mass of elevator element G : Newton's const. r : distance from center of Earth to elevator element v : speed of elevator element
Because gravity and centripal force have to cancel,
G m_E m_e / r^2 = m_e v^2/r
or
G m_e / r = v^2
So, if you are at distance r from the center of the Earth, you need
v = ( G m_e / r )^(1/2)
of speed to stay up. Note that as r gets bigger, v gets smaller. Now, to be in geostationary orbit, one needs to relate v and r like so:
v = 2 pi r / (1 day)
and one gets the answers for r and v. (something like r= few 10^5 kms and v = ~7km/s.)
Because this elevator *from top to bottom* has to be in geostationary orbit to even exist, the bottom part will be moving too slow and the top (if it goes past the geostationary point) will be moving too fast and will want to fly off. To keep everything in check and together, some bad ass rope has to be used.
Let us assume one can get something that is 1) strong enough so it all stays together and 2) light enough so the graviational pull of the lower part of the rope doesn't bring everything down. (Remember gravity gets stronger as you approach the earth.) We now have a perfect system in theory and if all there was in the Universe was the Earth and the elevator, it just might work, and once you have it built, don't touch it because if anything changes in v or r, the whole thing will come down if it doesn't snap off first.
What I mean is, the whole elevator is going to be undergoing perturbations from a number of graviational sources like the sun and moon. The platform will have to have some thrusters on it to *constantly* correct for these perturbations and also for the load that is being hauled up the rope. Can you guess how much energy you might need to compensate the load on the rope when something is going up? Think about energy conservation. It'll be alot like the energy needed to put the load into orbit via run-of-the-mill rocketship.
So, to me it just doesn't look feasible (ie worth it). Feel free to tell me otherwise.
PS. This would be an awesome thing to put into some mechanical simulation software.
Since some of us figure we owe our petroleum resources to dead dinosaurs, it stands to reason that the next form of life on this one-day-to-be-post-apocolyptic planet will filling their gas tanks with dead humans.
I have to agree with this. There *is* a pattern here. IF you dropped out twice becuase of lack of interest, what's going to be interesting enough to keep you there the third time?
If you've had a business now for 3 years, then obviously you have something there to warrant your interest and time.
If you really want a degree, maybe check out how you can get one in the mail.
The discussion referred in the headline is all about whether to get your girl a diamond engagement ring even though you know you're going to get gouged. There's also the issue of labour abuses when these things are taken out of the ground.
Most people didn't seem to have a problem with that stating that if a diamond is what their girl wants and will make her happy, that is what they will get her lest her friends make her feel bad for not getting one.
Well, at least now we have a great alternative. Instead of having miners who are working for a pittance dying in the mines so your girl can show a rock to her friends, you can have one made of someone who's already dead.
I hear dead people don't mind being made into diamonds.
Right. So let's all let the ethics slide, slide slide. But I dirgess; I want to address the matter in a different way:
What I haven't seen suggested yet is that the issue be brought up with the girlfriend in question. Why not ask her how she feels about the matter? Maybe she's dreading the thought of a diamond. OK, maybe not. But if you bring up your concerns with her, it will 1) show her that you actually care about something other than programming and getting laid and 2) tell you that you are or are not going to get married to someone who at least cares about your concerns. Listen to her reaction when you bring this up. See if she is actually listening to you.
Who's to say an engagement is a once in a lifetime event anyway. It wasn't for me and it probably goes for a hell of a lot more people than that - 50% divorce rates and all.
Up until this point in the discussion, it's pretty clear alot of people don't take you seriously. Some don't think you'll succeed, some are just wanting to make a joke at your expense. So, unless you are some serious nutcase (which I personally don't think) wanting to go out with the biggest bang possible, putting your life on the line to you is a very serious matter. So, the question: what are you thoughts and feelings toward your detractors?
So, whaddya think'll be more probable in the next little while? Planes coming down and runnin' into shit because of this buggered software or some terrorist hijackin'?
I say terrorists, 'course.
Now, where'd I put my gun?

What Free Cable?

This is what the cable providers will try to tell you.
My father had a cable modem installed from a Canadian cable provider (Shaw or Rogers) a couple of years ago. When he ordered a cable modem, he was informed that he would also have to subscribe to a basic cable package. Needless to say, my dad's not a big TV fan and he didn't want to pay for something he never uses. (Who does.) He is also a persistant man, and finally convinced the company to give him the cable modem only.
Upon having the modem installed, we did a check (temporary, of course) to see what kind of channels were available TV-wise. We did get channels 2-13 with great reception but no more as there was probably a filter on the line. I hooked it up again temporarily last summer when I went back to visit. This time only channels 2 through 5 or 6 were available. It seems that the cable company doesn't trust anybody and had put an even more restrictive filter on the line.
Now I'm not one to get Dad into hot water, so I left well enough alone. But there are people with easy access to the cable box feeding the house. The only thing keeping you from getting tons of channels of crap is going out and removing said filter.
...And remember to wear gloves and do your neighbours', too.
Hell, Ellison would do something loony like buy Costa Rica and turn it into the Federated Republic of Oracle, complete with its own airforce and navy.
And government. The new DOJ of the newly federated banana republic will get to prosecute companies that operate with business practices in conflict with Microsoft. These unfair business practices will be treated as treason and the offenders will be "deleted".
Judging by the last letter, it appears that Mr. Murphy has just done all the work that AFGAss' lawyers should have done in the first place. Maybe next time Tom should send along an invoice, say, for legal research at the rate of $200/hr or whatever lawyers charge nowadays.
"The rights enumerated in the Constitution are inalienable and shall not be infringed." Period. End of story. It shouldn't matter whether we're talking about the government, the RIAA, or your best friend.
If the BSA (BS, eh?) is allowed to impose their will in such a way as is suggested, then one might as well not have a constitution at all.
From the CNN article: "We know that credit card numbers are bought and sold over the Internet because they have real cash value"
I'm wondering how one pays for these numbers or other information. By credit card? Ha.
I think having to exchange monies for whatever information defeats the idea of this anonymity that IRC chatrooms provide. Maybe one can send cash to a P.O. box somewhere. Still not 100% foolproof since someone can wait to see who shows up to collect the money.
And, haven't you heard not to send cash by the mail?
Napster and all the other music sharing schemes allowed one to sample music from all over the place: independent stuff as well as from the companies that make up the RIAA and friends. Could it be the real reason that Napster was such a threat was it did just that? People all over the world were exploring their musical interests freely and widely and it wasn't just confined to what got pumped out of (most) radio and MTV.
What the RIAA is afraid of is NOT music piracy, per se, but the threat of the general public's musical tastes growing bigger than the set of bands they happen to be promoting.
So, now we're talking about copy protection. If the RIAA and friends get their way, we will only be able to buy CD players, etc, that will play CDs with their proprietary copy-protection/encryption scheme.
Think about it, if you wanted to listen to music on digital media, you'd have to buy THEIR music. I only hope this is a paraniod fantasy, but I can see where this is going.
...then that would set off the alarm bells (figuratively speaking, of course) and the bar might assume it's a fake ID.
But.... if the strip can be demagnetized, I'm pretty sure it can be re-magnetized, say with a different name and address. It seems to me the only thing the bar is interested in is collecting your information. If Joe Blow's name pops up on the screen, they're happy, hand you back the card without even checking the info on the front. I'll bet in most cases this is what will happen. You walk away knowing your mailbox is not going to get more full in the following weeks.
This might be trickier to do if the info on the strip is encrypted. I don't know for sure if that's true, but in any case, there are ways around that as well.

Liquid hydrogen is much more efficient in terms of energy/unit weight than kerosene.
It's cleaner burning, as well.
