NX is not a new thing, and neither Intel or AMD did it first. SPARC's, UltraSPARC's and Alpha's have had this for some time, and it wouldn't surprise me if its in the Power chips as well.
As far as it not being on older processors, I assume you mean older ia32's, and surprisingly this was brought up in a MS TechNet event I was at on Thursday. I don't know all the details, but he presenter said it was in older chips, at least back to the original Pentium if I remember, but with the way ia32 chips do paging, it was never implemented in the OS's until recently, which i can only assume the Athalon64, Opeteron and Itanium do this differently, but don't quote me on that.
Personally, I'm just wondering exactly what ia32 chips will Linux and OpenBSD use NX on.
On a far more serious note, XP SP2 adds this same functionality, except its only supported on the newest processors from AMD, the Athalon64 and Opterons. So does this, and the support for it that OpenBSD added to the i386 port, have the same limitation?

There's a big ass, well ok double wide, Help key on the Sun Type 5 I have. I like the way it feels really, I wish i could use it on these systems.
If you talked to most people you'd probably find F1 for help is the only function key they use, and they'd have a whole list of 'useless keys.'
When you go to buy a book at Chapters or where ever, do you get upset that the competitors books are also on the same shelf while your looking for a specific title? When you go to Amazon do you type in the specific URL of the book you have decided to buy or did you search for the title? By the time you have decided to buy the book other ads mean very little, you've already made up your mind. While you're in the process of deciding you are searching, and I don't know about you, but when I'm looking for something, I like to know all my alternatives.
Solid numbers, unfortunately no, but we can draw some conclusions. That harbinger of doom Netcraft, in the May 2004 internet survey has 33,892,817 sites running Apache, 67% of surveyed sites, with IIS at 10,858,168, or 21%. If we assume that the Apache sites are nicely split between Apache 1 and 2, thats still 33.5% for each putting both ahead of IIS, which also assumes that there is only one version of IIS deployed, which would be incorrect since 2k has IIS 5 and 2003 IIS 6. Now from what I've heard, Apache 2 is probably deployed less then 1, but either way you slice it, Apache has more sites then any single version of IIS.
Now while an exploit that runs on Sparc wont run on MIPS or x86, the flaw itself is there, and thanks to cross compilers, it wouldn't be much of a problem to recompile a tool to take advantage of any problem.
Good of you to propagate this idea, except it doesn't hold water. May I draw your attention to the Apache web server vs. IIS.
Windows is indeed a larger target, but the fact that Windows gets hit more often is its the easier of the two, virus writers are just like the rest of us, lazy. These flaws in Linux differ from those in Windows in that its so much easer to exploit the Windows ones.
Windows has a larger attack area, but whomever is the first to successfully attack and damage Linux in the same way is going to go down in history, whereas who cares about who writes these, there's no skill involved.
If your buying a book about Linux, or Unix in general with an aim to deploying something, you do realize that Microsoft IS an alternative solution. Amazon and Microsoft have done nothing wrong. Your searching for a book on say Operating Systems, guess what category MS falls into.
Stop whining about everything, it makes you sound like little children throwing a temper tantrum when things don't go your way.
...a significant popularity. You mean just like Mono, or WindowMaker, GNUStep, DragonFlyBSD? Its a miracle when any piece of software, no matter what it is or what license its under, becomes popular. Simply taking a closed or heavily guarded app or language, remember the specs and Java API's are there for anyone to read, and turning that into an OSS project is not going to make it more popular, but will make it a lot less useful to Sun. If Microsoft suddenly opened Windows tomorrow, would that make Windows magically better then it was today? Would you spend the time submitting patches to a system that you would have to give up to Microsoft?
Java is Sun. While that probably doesn't mean all that much to most people, it does to Sun and everyone whose spent the time and money to certify there apps as J2EE Certified. Sun would have to be smoking some really good stuff to think that giving that up would be a good thing. Java and C were made for very different reasons, C was to be the prefered language for Unix development, so it was stupid not to have it open and standardized as Unix went down the same path, Java was always concieved as something that Sun would keep, leverage it and open it enough that it would be used, but still Sun would have control.
Sun and the FSF have very different goals and the developers should know that. With the FSF assigning the copyrights is not necessary if I remember correctly, just requested because the FSF is in a better position to keep the software free, I doubt that the same would be said of Sun, even if they did keep them free it isn't their chief goal.
I really can't see any good reason for Sun to open Java or Solaris. They won't accept patches unless the copyright is assigned to them, and Sun will have a license that wont allow code from GPL work to enter Solaris or Java and vice-versa. If they really did, I would take it as more of a "We Give-Up" move just before everything falls apart. I personally would hate to see Sun go.

I dunno there's some kids around here I'm about ready to shoot, they have every damn car that drives by honking because of some stupid hockey game, and it goes on for hours before and after into the night. I'd like to kill those damn kids and every one who honks.

So let me get this straight, you have XP, 2 support incidents for free, NO software, NO development tools, and it seems you think that MS is the devil, and you pay $150 for this pleasure, yet you whine about the choice of free with community support or $66 for a years support in addition to the community support, with thousands of applications and more development tools then you can shake a stick at.
Between us, where you believe every Linux company should bend over, kiss your ass and give everything to you on a silver platter and if they don't they're as evil as MS, or me who actually understands that people have to put food on their families table which means shipping a product that costs money, how am I the one holding Linux back. It seems that if it were up to you, there would be no Linux business to be held back.
Heaven forbid a company makes a profit. Mandrake, Red Hat, SuSE these are all *commercial* distros. You do understand the concept of Commercial right? No? Well here let me help you with that
One clear, short definition is - Commercial: Having profit as a chief aim.
Unless its stipulated in some license other then the GPL, Mandrake is under no obligation to provide a free download product, they however chose too. In order to make money, actually remain in existence, and do all those little tweaks and make those configuration tools that make Mandrake Linux something other then just a bunch of packages, they have other products that build upon the free one, add value to it. So yes you should be modded down to oblivion for that nice shortsighted and uncalled for comment.
If the codes were open, you could make any change you wanted to the system, or possibly ignore things you otherwise wouldn't have, because chances are completely open codes will allow for home diagnosis kits, and not every home mechanic is really qualified to declare something is harmless.
Chances are the reason they believe that its your right to do whatever with your car but see no problem closing all computer systems, is that they understand cars. They grew up fixing and tinkering with cars, and they spent a long time with the belief that computers are these magical, mystical boxes that only the most intelligent people could possibly understand, so they regulate these 'protections' according to what they understand.
Its not all that hard, and Sun didn't have to use DRM at all. I have a SparcStation with dual HyperSparc modules. Lets look at a quick rundown of available OS's
Solaris - Fully Supported up to v9 OpenBSD - Single Processor only, some hardware not supported - ie on-board ISDN NetBSD - Single Processor only, some hardware not supported - ie on-board ISDN Linux - Small distros only, questionable hardware support
Considering I bought it to be more then a paperweight, Solaris is really the only choice for the system, and it didn't even take DRM to ensure I ran Solaris.

FC1 didn't have a problem with it, other distros don't have this problem, so what changed? FC2 is released and all of a sudden, data gets destroyed points to FC2 as the problem. Just because Windows creates a slightly different table then other systems doesn't mean its wrong, broken or has a bug, FC2 arbitrarily destroying it on the other hand is wrong and it is broken and it is a major bug for those who want to dual boot.
XP is 2000, only with an optional new UI. Anyone who likes 2000 and hates XP is talking about the UI and hasn't realized you can turn it off, or they don't know what they're talking about at all.
Well chances are they're not running the IOS, and they don't support anywhere near the functions that a cisco branded device does, so it won't have to do the same checks that the cisco does.

Unless you have some religious beliefs on the subject, there's nothing wrong with a dual licensing setup, So what exactly is your problem with it?
