The linux opterons we have run SuSE but since the opteron compiler support is still not up to par performance wise they have yet to make a big impact on run times. AMD needs to fund some good compiler development for this architecture, as it CAN perform incredibly, it just doesn't due to unoptimized compilers. Thats why IA64 still beats the pants off Opteron IMHO. The Madison chips from Intel are insanely fast, and their compiler is top notch. PG's compilers just aren't optimized as well as Intels, and it really shows. The numbers I've seen from AMD compared to the numbers I get, are two different things, obviously due to poor optimization at the compiler level.
I suppose I dont even know the purpose of this post, just some observations:-)
Nasa did this already. Spent a lot of money designing a self replicating macro-scale factory. Cost 11.7 million to do the study. The aasm link below is an abstract of the findings.
Except for a few things such as reduced cost and profit from the former crime, reduced head count in jails for the former crime and recuded need for violence associated with the former crime due to it being run by legitimate businesses.
Recuded profit means less money for organized crime to continue operations. Does it "guarantee" that organized crime would leave the alcohol business when alcohol was legalized? No. It happened anyway. We can analyze it all we want, the economics of fantasies can be anything you want. Taking historical experience into account is more concrete.
Legalizing drugs/sex/wagers would reduce organized crime activity. Simply stated.
What appeared in frodo's vision isn't anything from the scouring of the shire, nor was it in Sams vision in the book. The visions they had were of after the shire had already been corrupted and turned to industry, Sauron had retrieved the ring in those visions. That hadn't happened in the scouring, there were no orcs in the shire, just men at that time.
Regardless, the scouring sequence was never filmed. The Palantir scene has to be included however, which I find odd that Saruman isn't part of that in some way. Sarumans demise isn't really important to the movies however, he's already served his plot purpose and is irrelevant now.
This will work just as well. So the average consumer will be hampered while the clued techy will be able to do what they've always done. Seems silly to me, to requiring others to provide a means to protect somebody elses property. Thats like the government requiring all theives to respect a "please do not steal" sticker on any car that has one.
Interesting, as when I posted this months ago, I was blasted in here for being a total idiot. Here's my post: http://slashdot.org/comments.pl?sid=74902&cid=6709 167
Anyway, this has been a long time coming, and it should be no suprise.
Dude, you had the desired effect. You want them to remember doing what they did wrong. So he gave you the silent treatment, big deal. Thats your issue. The discipline worked, and he isn't scarred in the slightest. YOU are.
Its the view that evil is as evil does. So if our modern democracies have done evil acts, proclaming others as evil for doing the same thing is hypocracy. Usually they are downright lies anyway. Iraq is a very mild agressor compared to the United States or Great Britain. So when is Bush going to bomb BG? Or Isreal? They have weapons of mass destruction, and have huge terrorist groups within...
The menu system is part of the receiver. I have all kinds of receivers and a DirecTivo as well, they all have different menus with many different formats. Some have a tv display, some dont, some offer more data, some offer limited screen real estate.
Thats today. I never said that had changed for RH9. That is changing for binary distributions in the future. Go read up on redhat.com
BTW all I am talking about is redhats official iso image, not a clone. Like I said, anybody can make those. Anyway, this is a silly conversation. Read redhats trademark notice. Read it again.
Yeah, you can make your own. You can't use their build of it without their consent, thats what I'm saying. You can always roll your own of their entire OS. You just can't call it redhat or mention its from redhat.
Ok somebody please point me to the page at redhat that says they will always give fully installable iso images to the community for free.
Anybody?
Since you cannot redistribute their new iso's anymore, well... The only mention of what you guys call the "free" os is the price tag of the unsupported versions - RH9 right now - for $149. Its only freely available as an iso because it came out before the license change. The source files will always be available, but dont hold your breath for them to take the time and effort to build a stable installable system for you to have for free and to give to anybody you like. You cannot do that. You can only give the redhat manufactured cd's away.
Ok maybe I'm an idiot. What I posted does seem to be the direction redhat is taking however. As a consultant you cannot sell redhat to your customers anymore. You cannot ship something with redhat on it. Read their license agreement. You must have a relationship with Redhat Inc. in order to do that. Perhaps they will still have the free OS's, I was told that they were ending that sort of distro method at some point however that does sound odd and maybe I am totally wrong. You cannot redistribute redhat. Which means you cannot have their future iso's on an ftp site, or available to customers.
You CAN use and redistribute the GPL's portions of their OS.. the source. Nothing with the redhat name or installer however. I suggest you investigate further redhats change in focus.
Go to the redhat site. Its not in any concrete document, its in the their changing business tactics. Read the new license for redhat software.
Redhat 9 is the last release you can go buy at the store, as somebody else posted. It also may be the last release you can download as a complete iso image to burn and install. I thought this had become more widely known in the community but I suppose it hasn't yet. Its been known to us at work for some time now. Redhat 9 is $149.00 now. Future releases will be commercially available from redhat, but you wont be able to get iso's that are installable out of the box so to speak.
I guess I cannot point you to any specific statement from redhat however, so take this all with a grain of salt. It is my understanding though of the future of redhat and free releases. From what I know, RH9 will be the last of the totally free installable OS's. Maybe I'm wrong though. Redhat is still fine tuning its position in this regard.
Redhat is no longer going to be making public releases, thats the point. There wont be any RH 10 or 11. RH9 is it for the free distro's from redhat. They are moving to data center class high end stable stuff, rightfully so IMHO. Now they can compete with the big boys in the big boys playground, which can't hurt linux. There are plenty of free unsupported alternatives to redhat out there for the budget minded.
You can just make your own build of redhat. Every piece of the OS is available as source rpms from redhat themselves, for every linux OS they sell.
Get em, compile em and install em. Of course, the nice gui installer is not free, nor is the support. But updates and the OS itself is free and will always be free. Its GPL'd. What you pay for is support and peace of mind. Thats typically what data centers prefer these days. I know that the managers see only free as in beer, so they look like heroes for saving on the budget, but what really counts is uptime and reliability. TCO stuff. So it costs 350K... How much would Windows cost you, and how much functionality would get from it? How about the equivilant PA-RISC machines or big AIX boxes? E15k's?
It turns out to be quite a deal! The support you get is worth it, and compare the price of that to a support contract with Sun!
Not entirely. Strong crypto requires good keys, you are right. What you have to understand is that most algorithms we use, you do not type in your 1024 bit key. You use a smaller key that is easier to remember. The 1024 bit key is usually a random number, which is what we are talking about here. The generation of that random number is what is most likely to be attacked. If the key can be partially analyzed, thats a crack in it and cryptanalysis is that much easier. True random numbers do not have weaknesses. Pseudo-random numbers do, and exposing any information about the algorithm used or the data source of the supposed randomness weakens the number.
Typing and mouse clicks are not truly random. You are typing words, probably english words, using a keyboard. That is a pattern and with proper analysis can be determined as such. A computer is a deterministic device which follows certain rules. Those rules will end up embedding themselves into the "noise" being generated.
Its not the quantity of random bits thats the problem with a PRNG on a computer, its the quality. Any seed used to a PRNG must be of good enough quality and quantity to thwart cryptanalysis of the PRNG algorithm. So you are right in a sense, quantity is valuable, but much less so than quality. PRNG's can be usefull if they are seeded properly, however they are still not considered strong.
Because sound is not random at all. White noise is, but how often do you hear that? Not often. Voices, cars driving by, phones ringing, all of these are patterns. Patterns lead to cracks in the numbers that can be culled for weaknesses in the algorithm. This in turn leads to knowledge of what algorithm is being used, which in turn leads to a directed cryptanalysis of the data, exactly what true random numbers are meant to avoid.
Even using mouse clicks, keystroke times, etc. is not random. Thats why its called "pseudo-random". Processing normal everyday sound through a PRNG (pseudo random number generator) is still only pseudo, not real.
People have been working on this problem for decades. Trust me, what you are asking about has not only been tried, but been used and even attacked.
How in the world is your DOB hard to get? I can run a $39.95 report on you on the internet and get that plus your last 3 addresses, phone numbers and employers. Its printed on your drivers license, so its considered public knowledge about yourself. LOL that is the silliest thing I have heard all day..
Yeah Randy had his compute blink his NUMLOCK light in morse code to defeat van eck phreaking. He would have fake shit on the screen and the real info coming out of the blinking light. Cool scene in the book, and a nice look at how to deal with known active attempts at getting at your data, and defeating it right under someones nose. Neat!

Yeah, its not like IBM wants a viable business model.
Besides, SCO owns the IP at sun, not sun.

Hmm, having security critical files such as at.allow and at.deny on a read only filesystem... interesting...
