I have never seen a program that needs root priveleges to run. There are many that default that way however. Take for example tcpdump: Typically it is run as root, but, this is only because it needs to be able to set the ethernet adapter to promiscuous mode (which by default can only be done by root). We can always change the permissions of eth0 to allow it to be put into promiscuous mode by another user if we want.
The statement that there are only two levels of security is completly untrue. You can have as many levels of security as you have users and groups.
You should know then that UNIX systems allow you to change the read/write/execute permissions on any file on the system, and since everything is a file you can use this to control who can use what devices. You can also manipulate the user whose permissions an executable will use to run.
Granted, systems often come with stupid default permissions, but that's hardly a reason to write a new OS.
There's no reason why a (sc)ram jet has to be powered by hydrogen, you could probably power one with kerosene if you wanted. As a matter of fact there was a USAF project a few decades ago to develop a fission powered scram jet ( Project Pluto) for deliverng nuclear warheads. Needless to say it wasn't nearly as environmentally friendly as hydrogen power.
Also, I've seen ram jets built by hobbyists that about the size of a soda can - scram jets don't neccesarily have to be any bigger.
I think scram jets can be developed into a very viable means of providing very fast, cheap, sub-orbital propulsion.
I'd imagine that a couple miles of magnetic linear accelerator might do the trick to get them up to >= mach 2. Wouldn't be practical unless you planned on launching a lot of them though.
Yes, I propose a system whereby unused plutonium and other weapons grade radioactive materials are destroyed by rapid and perfectly symetrical implosion. That should solve a lot of problems.
You should note that that isn't the real Heidi Wall that you are responding to, note the spelling (Wall vs. Walll). You've just been trolled by one of those 19 year old boys;-)
Simple, the enourmous magnetic field produced by the coil induces a secondary current in the object to be crushed. The induced current produces its own magnetic field and this is what the primary field works against.
since leagaly it restricts them from using GPL'd sorce code in their software.
No, it doesn't. It simply means that if they used GPL'ed code they would have to GPL the rest of the package that uses the original GPL'ed code. They are perfectly free to do that;-)
If I use my CD-R drive to backup my files on my computer, I have cost the music industry nothing. It is no different from me backing up to floppies, DAT/DDS tape, or stone tablets. I don't mind the music industry recouping losses from people who have illeagaly copied the property of the RIAA, but they have no right to recoup it from me. Any solution wherein I subsidize the piracy of others is unjust.
Also what the hell is it supposed to mean when you say the RIAA is suffering from slowing in their sales growth? How long can you expect sales to grow in any market? Am I supposed to spend more on music every year untill my entire income is spent on music? Any steady growth in any market is a temporary phenomenon or is limited by population growth (which has noticably slowed in western countries latley).
P.S. in case you haven't noticed the recording industry has been proposing simlar taxes on DAT tapes, copact flash, smart media, hard drives, and audio related computer peripherals prettty regularly lately. It looks to me like an attempt to shake down consumers more than recovering unproveable losses.
I can understand why media compaies would want to control their entire consumption chain. They want as much leverage over their marketplace as possible in order to maximize their profits, minimize their costs, and eliminate their risks.
What I don't understand is why this would be good for consumers or why I should support it. Convince me.
So are saying is that we should be grateful to companies like Rambus that encourage standards that become widely and freely adopted and then insist that suddenly everybody owes them royalties? Sony and Phillips may have invented the CD format but if they push it for free and only later decide they should be compensated, well, at that point they are no better than heroine dealers passing out "free" samples.
Now all this is really beside the point because no one is suggesting that Sony and Phillips be compensated for providing a standard. What has been proposed is a tax on recordable media to cover what might be lost to piracy. The revenue from this tax wouldn't go to the creators of CDs, it would go to music publishers who claim to be losing sales.
I've seen the term "unobtanium" floating around for years, generally just referring to some material (imaginary or otherwise) that was incredibly rare/expensive/or just plain unobtainable. I don't think Jim Cameron invented it.
Aerospace engineers used to use it in reference to titanium, before it became more readily available from the former U.S.S.R.
Perhaps you can clarify how CDs not being used for their original purpose constitutes a loss for Sony and Philips? It's not as if there were such a limited supply of blank CD media that whenever one is used for data that's one less that could have been used to sell music. CDs are still doing everything they were designed to do - other applications are just gravy.
But consider (aside from conditions that exploited workers are forced deal with) how many air-conditioners that Malaysian factory produces as compared with the number of workers employed there and in the distribution system.
Now think about how long each of those air-conditioners should last.
Compare this with the efficiency of a dedicated slave with a palm leaf.
Obviously people still have to work, my point is that for each persons labor much more can be achieved and gradually we all should become richer.
What percentage of the population now can afford an air-conditioner as compared with the percentage of people able to afford a dedicated palm waving slave 3000 years ago?
p.s. I apologize for the excessive use of the A.C. example
Is it so incocievable that human advancement could provide the means for everyone to live in relative luxury? You no longer need a slave with a palm leaf to keep you cool - you have air conditioning. You no longer need a coach driver and a team of horses to get you where you want to go. You no longer need a private courier to converse with someone accross town - you have fax machines and email and the telephone, etc... As humanity's pool of knowledge and societal infrastructure improves we can all grow rich, wealth doesn't need to built on the backs of the poor.
We may not be there yet but we are working on it. The more people realize this the sooner it will happen.
Yeah but the RIAA isn't the government. I suppose you wouldn't mind a tax on (oh say) ethernet cables that was always funneled straight into my pocket without you ever having a chance in hell of reaping any benefits? Would You? If you want the RIAA to leave you alone go buy the original cd.
I think that trolling often plays a critical role in discussion boards. It can force us to reexamine our opinions, remeber why we originally formed our opinions, and consider the merits of alternative opinions. Without trolls discussion would stagnate and ideas would never be fully explored. People that get really worked up over trolls that simply put forth non-party-line ideas are the ones that really need trolling.
All the natalieportmanbeowulfgoatse.cxhotgrits crap is just noise not real trolls.
Actually we've had liquid clutches for ages now - they're called tourqe convertors and just about every car with an automatic transmission has one. Granted they aren't as efficient as mechanical clutches and probably can't be as closely controlled.
I'm guessing that will be IDE/ATAPI devices rather than trying to use the old floppy bus(ala LS-120 & internal zip drives). As for floppies being unreliable, I aggree the medium isn't very stable but what do most pc's still use as the last resort bare metal recovery method?
Would having full net access to your records really be helpful to an 83 year old grandma that only speaks Spanish.
Probably not, but I would sure like it. just because it wouldn't benefit everybody doesn't mean it's not a good idea. Just as long as it isn't mandatory.

Uh, actually none of these statements are true.
