Yes, but bottom line is they *are* faster. Significantly faster in fact. Anyhow, my main point was: why not concentrate on including Reiserfs in 2.4 since it is already available and works great? If SourceForge runs it, then it sure is stable enough for my workstation.
Also, wouldn't multiple swap partitions seriously fragment the memory, as well as causing intermittent instances of downtime just to copy the contents while the partitions are being made
uhhm, what? Where the hell did you get that idea? If you create an additional swap partition or swap file, it just gets added to your total swap space. And if you create the swap partitions on different disks, this will even increase performace. Finally, the whole reason for putting swap on a separate partition as opposed to a file is precisely to avoid fragmentation (well, there's also no fs overhead). ___
So will samba be able to support Microsoft's bastardized Kerberos? What about Active Directory? Also, how does the "release" of MS Kerberos specs affect the development?
Oh, and is it possible to run samba as a non-PDC server within Active Directory network? (that is right now) ___
So let me get this straight: if you just select "encrypted", it magically "encrypts" the file? What encryption method does it use? Where does it store the key? Or does it just do xor against "Netscape engineers are weenies" written backwards?;-) File system encryption is kind of pointless if the key is stored somewhere in registry. ___
I don't see why apache-ssl would be faster than mod_ssl. Just because it's patched and compiled in doesn't make it faster. It still needs to perform the same tasks. The difference in spead comes from the efficiency of the code, and modularity does not necessarily hurt it. Can you explain your reasoning?
But quantum computer is non-deterministic. You will not argue with that, will you? So solving, say, TSP in poly-time using a QC is really just a matter of finding the right algorithm. ___
Re: Is this problem NP complete?

Does P = NP?

Just to clarify, Cook showed it for 3SAT. 2SAT is NOT NP-complete. There is a poly-time (perhaps even linear? don't remember) algorithm to solve it. ___
The definition is indeed correct. NP-complete problems can indeed be solved in poly-time by a non-deterministic machine (such as a quantum computer). I don't think human brain is non-deterministic though. (?) The statement "NP complete problems can be verified in poly-time" is a simplified definition. ___
You should review the definition of NP-complete problems. If a problem is NP-complete, it can be poly-time reduced to any other problem. Therefore, if you find a poly-time algorithm for *one* NP-complete problem, you automatically find a poly-time algorithm for *all* of them, which proves that P=NP. Of course no one has been able to do this yet, and I am sceptical this solution will pass the peer review.
There is one other possible outcome, namely P != NP. In order to prove that you'd need to find a problem that is in NP but not in P. No one has been able to do that either. (i.e. there is no proof that a poly-time algorithm cannot possibly be found for NP-complete problems). ___
Totally agree. I have used Dells personally (the guy who buys computers at my company buys from Dell exclusively). I was amazed when I opened the case of one machine and looked inside. The components they use are the really cheap kind. They even cut down on CPU cooling: instead of using a dedicated CPU fan they just put a really oversized heat sink on it! Basically, there is no way I would have put this crap in a machine I was building for myself. You can't beat Dell's warranty and name recognition though (but that's mostly a PHB thing). ___
This doesn't make any sence. The only reason I can see for buying from Dell is precisely the warranty. They have nothing else to offer besides that. If your Dells come with no warranty, you're much better off buying clones from your local hardware store. Then you actually do get warranty (not next-business-day like Dell, but it covers parts & labor which all I need), and save a lot of money as well. Oh, and you can configure your machines exactly the way you like, which is something I value a lot more than the label. ___
Can you build SMP systems incrementally? I.e., buy a 760 motherboard and a single CPU for starters, and then add a second CPU as an upgrade a few months later?
Man, that's the whole point of SMP. It would have been pretty useless otherwise. (see also: scalability) ___
Slashdot has been really disappointing me lately. Besides the usual crap that is posted in the news, look at what Ask Slashdot has turned into. The dumbest questions get posted. Like "I want to find a job" thing yesterday. Now this. If Christopher Cashell ever bothered to go to any of the hardware sites, he would find the answer to his question in about 5 minutes. Let me guess, the next Ask Slashdot question will be "What is Linux?" ___
You heard something, but it is wrong. Yes, there is (or rather was) a port of NT to Alpha. But it was not, repeat *not*, 64 bit. It did not use the Alpha platform to its full potential, so it was kinda useless. You are correct that DEC ported it to Alpha, not Microsoft, and, when Compaq decided that they will no longer port Microsoft's software for free, Microsoft cut all support for NT on Alpha and made it sound like it was Compaq's fault. Incidentally, same happened with other NT ports. e.g. SGI ported NT to MIPS.
Now that Microsoft cut all ports, there is only one platform Windows 2000 runs on - x86. And it doesn't look like this will change any time soon.
Access, VB and SQL is all you can do?? Well, you're lucky you got even this job. You should consider learning something useful instead of bitching about being unemployed. ___
Monopoly is good for consumers? Maybe in an alternate universe. You should take Economics 101. What you're saying is a complete bull shit, to put it mildly. Monopolies are bad for consumers. That is why anti-trust laws exist in the first place!
According to what you're saying, the planned economy of the Communist countries is the best, most efficient economic system. Well, we all know what happened to them. Soviet Union has already collapsed under its own weight, precisely because of extremely inefficient economic system. And many other countries followed. I'm sure that within a few decades this completely moronic economic system will go the way of the dynasaurs. ___
And what's the deal with them not liking Linux? They make all their money from selling hardware anyway, so it doesn't matter what OS runs on it as long as they get a sale. Sure you need Solaris on one of those E10000 but it makes sence to put Linux on their low-end boxes and Cobalt appliances. Besides, there are many things I like about Linux. I'd pick Linux over Solaris for a workstation any day.
Yeah, the short service interruptions do get annoying. I didn't say Rogers was perfect but it is reasonably good as far as reliability is concerned. And fast too. I do not use Rogers mail servers. Run my own. So I haven't had that problem. But I did hear the same thing from other people. ___

Organizations playing god don't deserve to be on the internet.
I agree with that. But it's not MAPS who is playing God. There is certain other organization that frequently attempts to do so.
___
Well, by that I meant the only one available in non-alpha/beta stage. None of the fs's you mentioned have been released in stable version yet.
___
Yes, but bottom line is they *are* faster. Significantly faster in fact. Anyhow, my main point was: why not concentrate on including Reiserfs in 2.4 since it is already available and works great? If SourceForge runs it, then it sure is stable enough for my workstation.
___
Then how come Reiserfs is so much faster than ext2? And I seem to recall that xfs and jfs also tout their speed.
___
uhhm, what? Where the hell did you get that idea? If you create an additional swap partition or swap file, it just gets added to your total swap space. And if you create the swap partitions on different disks, this will even increase performace. Finally, the whole reason for putting swap on a separate partition as opposed to a file is precisely to avoid fragmentation (well, there's also no fs overhead).
___
Gee, wonder why. Might it have something to do with the fact that Reiserfs is faster than ext2? Much faster in fact.
