  2. costs on Spacecraft Launching Maglevs · · Score: 1

    Most of the costs related to space travel is related to the amount of fuel needed to get out of Earth's gravity well. Any small increase in weight requires a large amount of extra fuel, which in turn requires a larger rocket, adding to the weight. ANY reduction in fuel requirements reduces the cost at an exponential rate.

    Other options include using fuel which applies more thrust per mass. Chemical propulsion is very inefficient, but many of the alternatives take advantage of politically unfriendly qualities. Its hard enough to get a nuclear power source into space without half the world complaining about it. If a rocket was propelled by a nuclear reaction, you could bet the complaints would be much louder.

    There are many different theories about it. The simple fact of the matter is that all the matter in the universe may eventually be concentrated within a single black hole, but it will take a few more years. The universe is still young. VERY young. The universe will be something along the lines of 10^70 years old before it gets swallowed up like this.

    Another thing to realize, since empty space is more or less a sideeffect of the matter within it, if all matter is concentrated within a single singularity, there won't BE any space, and the universe will effectively disappear, at least back to the point it started at, a single point of high energy and mass, but no volume. BANG!

    However, there were multiple holes involved here, any of which could have prevented the crack if they had been patched. The first allowed the cracker to determine the directory structure. The second allowed him to write an executable file with contents of his choice, allowing him to run any program as a local user, and the third was the crontab exploit, which required a local user to exploit.

    The only one that is even remotely linux related is the contrab exploit, and it was a KNOWN exploit, so it should have been patched if this was going to be a valid test of the operating system.

I host MANY users on my system, and occasional use of crack shows that many of their passwords are frequently all to easy to guess.

  9. Stuff. on Dvorak On Linux And "The Big Time" · · Score: 1

    Talk about a man with no vision. The simple notion that the computer industry will topple over in a few years because everything will completed has to be the most absurd commentary, and the one that has been disproven so many times in the past.

    Why doesn't linux run on all these high end massive servers right now? I have a theory. Because 3-4 years ago when all these systems were put in place, linux wasn't a viable option. It was still in its infancy and wasn't yet ready for it. So these servers were designed and built with other operating systems and as they were updated, they maintained their current OS because frankly it would be easier to upgrade to another compatible operating system than porting to another. Far from impossible, but it would require a significant amount of work. So these servers tend to stay with their current system until they have a substantial reason to change.

    In the last couple of years with added support for
    SMP and with linux gaining ground on a wide variety of different architectures, linux is quickly becoming the OS of choice for new servers today. These little servers today will be the big servers tomorrow. It might just take a couple years before linux has a prominent place amongst the other big boys, but it won't be all that long.

    As for IRC, I found it rather interesting that he first states that NO IRC servers are run on linux, then he later revises his statement to imply only the big networks. In many cases, the same reasons apply. The big networks have enough problems as it is right now. The major operators probably figure, right or wrong, that keeping a standard platform set will help to minimize these problems. And since the other servers are running BSD/Solaris or whatnot, thats what they continue to support.

    I live in Texas, and what I say applies to Texas. I'm not a lawyer.

    There is no state income tax in Texas (not yet anyways), but we have a 8.25% (varies slightly from city to city) sales tax on consumer goods (except food which is tax exempt).

    If I, as a retailler, want to sell someone something, I get a tax license, NOT so I can collect and file sales taxes, I can do this without a license. What I need the license for is so I can purchase my inventory tax free. I just need to actually SELL my inventory or pay the taxes on it later.

    If I sell my products to a customer out of state, and ship the product there, I am not obligated to collect sales tax, and I therefore don't need to file any. Any product I purchase from out of state that I purchase for PERSONAL use I am not required to pay taxes on. However, if the product I purchase is for business use then I am required to pay a "use tax" on the product at the same sales tax rate. Its a business product mainly if I deduct it from income tax as a business expense.

    Where things get tricker is where services are involved. Certain services are tax exempt, such as educational services or legal services, but for the most part, a service must be taxed at the same rate as consumer products. If I sell my services to a customer out of state, but I PERFORM the service IN Texas, then I am obligated to file taxes on that service.

    There's no harm done in collecting sales tax from EVERYONE, even if they would otherwise be exempt and filing all of it. Trust me, the state won't care. You can also hike all of your prices to include the tax, and simply file the appropriate percentage, then just not charge any additional tax to anyone.

  16. Re:Script kiddie, no. on Mitnick Charges Dropped · · Score: 1

    The only TRUE injustice is that Kevin Mitnick does not have competant legal council. Its his own legal team, and their recommendations, that he give up his right to a free trial. They are the ones who continuously postpone the trial in order to review evidence. They are the ones who failed to do any significant research into the prosecution's claims to the effect that Mitnick had stolen, therefore caused a significant monetary loss to the corporations mentioned, which is the grounds the prosecution used to keep him locked up without bail.

    It may be an unfortunate set of circumstances, but the issue was compounded for other reasons. First, he has SEVERAL felony convictions already. Secondly, he has been known to flee to avoid
    prosecution in the past. This is a BIG No-no when you're trying to get bail in the future.

    Federal trials tend to take a long time. While 4 and a half years might seem like an excessively long time, it really isn't. Its only long while you're rotting in jail. For this reason, it is in the defendant's best interest to TAKE the speedy trail because it doesn't give the prosection a lot of time to prepare and its a lot easier to have a competant defense attorney find gaping holes in their investigation, which give plenty of opportunities for reasonable doubt.

    Since most of these "injustices" lead down to the issue of his defense, that leads to another issue. 2600 has been pleading for its reader's to donate to Kevin's legal defense fund. However, as of about a year ago, the most they were able to raise was $3000. While its better than nothing, it barely pays the daily salary for a good lawyer. It also happens to be less than 20 cents per reader of the magazine. Pretty pathetic when that's considered to be Kevin's major centre of support.

    Instead, he has 2 court appointed annorney's (the 40,000 a year variety) who's typical defense is to plea bargain every case. However, if Kevin was able to fight it, and in the chance that he could have won the case, it would have set valuable precedent for any of the state trials he was facing. Since LA dropped the case against him (probably since they don't really see the point of it anymore), this is less of a concern. But being aquitted for the same crimes in one court makes it a LOT easier to win the same battle in another court and the case would have probably gotten dropped anyways.

    Yes, in many cases he IS a political prisoner. And while slapping Free Kevin stickers on your bumper might bring awareness to an issue that most American's have probably never heard a word of, but in the long run, it really does nothing to help him. And if he wanted to go down as a martyr, the last thing in the world he should have done was plead guilty. Yes, I realize it might have meant more prison time, but until the trial, nobody really has a chance to embarrass the government with their shoddy excuse for evidence. Now that day will never come and they are free to carry out this sequence of events again in the future.

    But then I got to the point about making reverse engineering illegal, and that my friends is a serious issue. This could, and very likely would, make future products such as samba illegal. Now, that being said, a program like samba COULD be created and distributed anonymously. Its unlikely that anyone could be sued because they're using a product that was concieved of illegally, and being open sourced, nobody would be able to prevent anyone from picking up the project at any time.
    In fact, if the reverse enginner published the specs anonymously, than another coder could take over the project without (technically) breaking any laws.

    Still, I don't like it.

    I don't like any of it.

    Even the idea that a vendor would be forced to remote disable a product is sickening. I know its to prevent piracy, but its very nature is an invasion of privacy. However, there are adaquate workarounds to prevent this possibility. First of all, in order to disable the software, that software needs to be accessible from the internet. If that computer never actually ACCESSES the internet, then there's no way to disable it. Also, sitting behind a firewall or a masq.'ed network would also prevent this.

    Furthermore, assuming this is a method to reduce piracy, consider the fact that most commercial software products don't require any software keys to use the software, except maybe during installation. The reason they don't require you to enter your original diskette every time you run the program is they realize that its worth the risk of piracy to make it hassle free for the customer than to piss off half your customer base by making it difficult. Just a few mistakes on the part of the software vendor and they'll get some VERY bad press, along with some possible lawsuits. And you can be damn sure that they'll also lose those customers.

    Still, I'd rather see the government stay out of the software industry. Let microsoft have their monopoly. I think I'd be happier letting linux or some other product topple them on their own merit rather than having "help" by the government who will likely create dangerous precedent in the process that will give microsoft a card to play in the future when the tables are turned.

    I don't think that ISP's are obligated to disclose that they happen to be censored by software. It can be an excessive amount of trouble to keep up with all the software, along with how they work. Some use network or domain blocks, other use word matches, and most use a combination of the two. This causes a variety of problems. You have fly by night porn sites that exist in one place only long enough to alert the censors and get the service banned, then leave. And then you get whitehouse.gov banned because the word "couples" appears somewhere on the page.

    word and they censor the entire site, I can't control that either. I don't necessarily like it, but if someone can't access my site, I'll tell them to remove the software and try again.
