I never said it has no value, only that its value is limited. Expecting more from it than is possible is just setting yourself up to be dissapointed. Celebrate the achievement for what it is, as I will, but be realistic. Not only is it usefull for high altitude research, it may well inspire somebody to build a ship that can reach orbit. If so, it will have justified itself 100 times.
The main problem, I gather, is that the fuel used just doesn't have the delta-V needed. Another poster mentions using the technology to put up satilites, but unless my very well informed source Jerry Pournelle is wrong, that's not going to happen.
As I understand it, this ship can't make orbit, couldn't come back from one if it did, and has no clear path to an orbital vehicle. It's designed to win the prize and nothing else. Not that it's not an important milestone, mind you, but it's just a dead-end.
The real import of this is that people are trying to get to space without the government getting in their way, and willing to risk failure. They're doing things themselves instead of sitting on their hands waiting for somebody else to do something. It's this pioneering attitude that will take us into space to stay, not the NASA mindset of "risk nothing, even if it means nothing gets done."
I'm sorry, but that doesn't help. Not only don't you define (or describe) "sublinear," you introduce a new undefined term. I have no idea what "polynomial in log N" could be because you never mention which polynomial you mean. Please define your terms instead of introducing new ones.
And it runs in O((logN)^3) time. So not linear but sublinear unless my math is rustier than i thought.
I'm not sure just what you mean by "sublinear," but a few experiments show me that f(x)=ln(x)^3 goes up slightly faster than x does. Could you explain what you mean?
The next time you see an episode of Blake's7, look at the logo at the beginning. It's a Trek communicator, and not by accident, either. The show had a Federation like Trek, but topsy-turvy. Instead of sweetness and light, it was the Dark Side: watch your back and trust nobody.
The conscious production or arrangement of sounds, colors, forms, movements, or other elements in a manner that affects the sense of beauty, specifically the production of the beautiful in a graphic or plastic medium.
The study of these activities.
In one definition and:
A system of principles and methods employed in the performance of a set of activities: the art of building. And, A trade or craft that applies such a system of principles and methods: the art of the lexicographer. Nothing about it needing to be useless. Have you ever considered learning what you're writing about before posting?
I know it's a tad off-topic, but I always wanted to see Servalan get together with Ming The Merciless. Granted, she was more trecherous, but he had lots more loyal subordinates. Sometimes, killing people for their first mistake isn't the best idea.
The effects on Blakes7 were not borrowed from Classic Trek. They were lifted straight out of Dr. Who, another landmark BBC SF show famous for its cheesy effects.
I used to work for an ISP. We blocked all outgoing Port 25 to keep our customers from relaying. We also blocked inbound at first, to keep out spammers. This ran into trouble quickly. Not only are there services that don't offer SMTP, there are some that insist you use an address at their domain on all outgoing. We had customers that either couldn't send at all, or not with our address because their broadband carrier wasn't accepting their messages. The way we fixed this, we put up an authenticating server. This way, if you ouldn't connect directly through us you still had one of our servers you could use. Worked just fine, and made a lot of people very happy. I doubt we had as many as 0.01% of our customers complain about this, mostly because they needed to send work mail from home and their company insisted that all mail with the company address went through their own servers.
I must say that at he seems a bit full of himself, or at least, getting a bit ahead of himself. Given how many have tried and failed witht his problem.
Not really. He says it would be a good use, not will be. I don't see that as counting his chickens before they're hatched.
No. Or, at least, that's what we already do and it's called "factoring." Factoring large composite numbers is hard. Having a function that tells you how they're distributed doesn't help. Besides, this isn't related to the use of the Zeta Function in calculating the distribution of primes anyway.
Abberant doesn't have to mean malicious. It just means that they're someplace they don't belong. If you misaddress a letter, or misdial a phone number, the result is abberant because you end up somewhere you don't belong.
As long as we're allowed to patent business practices and most patents are granted without proper examination, there's a neat way to eliminate the problem: simply patent the business practice of patenting something that doesn't deserve one then suing everybody that's already using your idea.
Although the Hindenburg is often perceived as an advertisement against hydrogen, it was, in reality, more of an advertisement against using cellulose nitrate or cellulose acetate to add rigidity to the skin of a dirigible.
It's much worse than that. In order to make it look better, they covered the skin with a mixture of iron oxide and aluminum powder. That's right, boys and girls, they covered it with thermite! No wonder it burned so fast!
I know what their fist ship should be named: The Vulture, after the old TV show, Salvage, about a junk yard owner whe builds a ship to salvage moon-junk. His ship, The Vulture, used low-acceleration to allow him to use safer fuels. Neat idea, although the writers got a tad carried away with the possibilities after a few shows.
Unless you don't care about false positives, you don't block spam at the server by sending it to/dev/nul. You put it in a special folder that the end user can check. That way, false positives can be received, and you can adjust your filters as needed. Presumably, their spam filters were getting so overloaded that they couldn't even do this much.
Sometimes you have to do things like that because the caller wouldn't understand you if you tried to explain. Sometimes, it's not worth your while to try. If you really want to see what it's like "on the other side of the phone," check out this book of tech support horror stories. You'll have a little more sympathy for the techs once you've finished.
Alas, the cite you gave lists various rights and limitations on service providers, but doesn't define them. Can you find one that does so that we can settle this once and for all? Or, if it does define one, please quote it.
If Comcast nukes his account because somebody misuses his network from the outside, and he tries to use that as a defense, he'll be admitting he violated the TOS and AUP and get his account killed for that. Rather amusing, isn't it, that his only defense against having his account terminated results in exaxtly that.

Yeah, right. We'll only need a few quantum computers just like we only need a few computers. Thank you Mr. Watson of IBM.

The headers on this UCE show that it came from your service. Please deal with it:
Followed by the complete message with all headers. Short, simple, polite and to the point.

I don't think it's been proven to be hard in that sense, but it certainly isn't easy, and that's what I meant. Thanx for the amplification.

Come to the Darknet, little cracker; you know you want to.

Linux is very user friendly. It's also very fussy about who it makes friends with.
