    IMO, mainstream religion hasn't been about fear since the Middle/ Dark Ages.

    Power and control? Sure, depending on your view of religion.

    Fear of death. That's why religion was invented and why it will always exist.

    What astounds me about this thread is that most people are treating Conroe like it's some second rate, compromise chip, like it pales in comparison to the Woodcrest, which is absolutely ridiculous. The conroe is a revolutionary chip, with virtually identical architecture to the Woodcrest. It's only downside is that you can't run dual conroe's and the bus speed is slightly different.

    If the entire Mac Pro line came out with Conroes, which are dual core, we would have excellent and fast machines (for the record though, I think we'll see Woodcrests). My guess is that we may see at least one lower-end Mac Pro or headless media unit with a Conroe but in all likelihood, most of the Mac Pro line will use one chip because of the engineering costs associated with different socket and motherboard designs.

    As for Conroes being too hot for an iMac, that strikes me as ridiculous. From what I've read, conroes use 40% less power than Pentium D's and are very efficient in terms of power to performance. Merom is a laptop chip and I'm not sure it will ever end up in a desktop system, even if it is the same socket as the Yonah.

    beyond this robin hood mentality
    I think you may be misunderstanding the natural human desire to be free with a fairy tale. No matter where you look in history, humans are always trying to find ways to increase their freedom and decrease oppression. This is not "Robin Hood", this is nature.

    If only people could work up a tenth of this kind of moral indignation over things that really matter, like poverty or racism.
    Start working at changing the world from where you stand. No one needs to "wait" to care. And what you care about is of much less importance than the fact that you feel anything at all.

    Okay, here are a few relevant portions from the iTunes Music Store Terms Of Service (TOS).

    Security. You understand that the Service, and products purchased through the Service, such as sound recordings and related artwork (�Products�), include a security framework using technology that protects digital information and limits your usage of Products to certain usage rules established by Apple and its licensors (�Usage Rules�). You agree to comply with such Usage Rules, as further outlined below, and you agree not to violate or attempt to violate any security components. You agree not to attempt to, or assist another person to, circumvent, reverse-engineer, decompile, disassemble, or otherwise tamper with any of the security components related to such Usage Rules for any reason whatsoever. Usage Rules may be controlled and monitored by Apple for compliance purposes, and Apple reserves the right to enforce the Usage Rules with or without notice to you. You will not access the Service by any means other than through software that is provided by Apple for accessing the Service. You shall not access or attempt to access an Account that you are not authorized to access. You agree not to modify the software in any manner or form, or to use modified versions of the software, for any purposes including obtaining unauthorized access to the Service. Violations of system or network security may result in civil or criminal liability.
    and

    You agree that you will not attempt to, or encourage or assist any other person to, circumvent or modify any security technology or software that is part of the Service or used to administer the Usage Rules.
    So, basically if you use PyMusique you are in violation of the TOS and because you need an iTunes account to even make use of PyMusique, Apple will know who is trying to violate the TOS.

    Thus, as I said before, you'd have to be pretty stupid to even try and use this software.

    This thread is getting too funny. Apple has been so far behind on power these past few years and now we get the chance to use Conroe, and suddenly that's not good enough for the Mac snobs. Conroe is an extremely fast chip (especially compared to G5), so I don't get why some people think it's a bad choice for the pro-line up. Sure, it can't do smp, but not everyone needs or want to pay for quad processing.

    So, aside from the ability to do multiple processing, what advantages does Woodcrest have that make it mandatory to go in the pro-line? How much "faster" is it going to be over the Conroe? It's my understanding that they are identical in that respect.Yes they are. I agree with you. But when I wrote that earlier in this thread, someone wrote that economies of scale dictated that Woody goes in everything Pro rather than only in the Quad. Makes no sense to me either. I think all non-quads should be Conroe.

    if you don't need all the power you can get the mac pro is not for you, apple does not do a consumer tower and most likely never will, they simply must have a quad settup and if they have two configs of them (a 3GHz and a 2.66) they may as well keep the low end option on the same platform, this has been said again and again and again, conroe is not bad it just does not make sense for apple to use it in the mac pro, conroe goes in the imac.

    I wasn't saying that I don't need power, I just don't want to pay premium for quad processing with expensive overrated chips. And just because I don't want a Quad doesn't mean should be stuck with an iMac. I would be content with a Conroe running around 3GHZ in the currently shipping configurations. By your post, I get that you think the Conroe is for prosumer/home computers and the only "professional" level chip is Woodcrest. Apple has been shipping a mid-range G5 dual2.3 for quite awhile now. What's wrong with them shipping something similar with Conroe? Oh, wait... that would be wrong, because by your account, Conroe is NOT a professional chip. I disagree.

    Wow I missed a lot by spending all of Friday away from this board. I am way behind in posts here, and I'm sure I'll miss a lot of things worth comment. But anyway, the code fragment:


    int x1,x2,x3;
    for (x1=1; x1<=20000; x1++) {
    for(x2=1; x2<=20000; x2++) {
    x3 = x1*x2;
    }
    }

    Is a very poor benchmark. Compilers may be able to really dig into that and make the resulting executable perform the calculate radically different. In fact, I can tell you the answer outright: x1=20000, x2=20000, x3 = 400000000. It took me 2 seconds or so. Does this mean that I am a better computer than a G4 and a P4? No, it means I realized that the loop can be reduced to simple data assignments. I have a better compiler, thats it.

    Anyway, lets pretend that for whatever reason compilers did not simplify that loop AT ALL. Note that this would be a stupid stupid compiler. At each stage, x1 is something, we ++x2, and we set x3 = x1 * x2. Now notice that we cannot set x3 until the result of X2++ is known. On a pipelined processor that cannot execute instructions out of order, this means that I have a big "bubble" in the pipeline as I wait for the new x2 before I can multiply. However, after the x3 is started into the pipe, the next instruction is just another x2++ which does not depend on x3, so I can do it immediately. On a 7-stage in-order chip like a G4, this means that I fill two stages of the pipe and then have to wait for the results on the other end before I can continue. You see that this is very inefficient (28% or so). However, the G3 is a 4-stage design and so 2/4 of the stages can stay busy, resulting in a 50% efficientcy (so a 700mhz G3 is "the same as" a 350mhz G3 at 100% and a 800mhz G4 is "the same as" a 210mhz G4 at 100%). These are of course simplified cases, the actual result may very a bit for some obscure reason.

    Actually the above stuff is inaccurate. The G3 sports 2 integer units AFAIK, so it can do x3 = x1*x2 at the same time as it is doing x2++ (for the next loop of course, not this one). This means that both pipes start one bit of work, then wait for it to get out the other end, then do one bit of work again. So this is 25% efficientcy. A hypothetical single-pipe G3 would do x3 = x1*x3 and then do x2++, however it could not do x3 = x1 * x2 again until the x2++ was out the other end, which takes 4 cycles and started one after the previos x3 = x1*x2, which should mean 3 "bubble" stages and an efficientcy of 20%.

    Actually, it may be worse than that. Remember that this is in a loop. The loop means a compare instruction (are we done yet?) followed by a jump depending on the results of the compare. We therefore have 4 instructions in PPC I think per loop, and we can't compare x2 to 20000 until x2++ has gone through all the pipe stages. (Oh no!) And we can't jump until we know r]the result of the compare (oh no!). Seeing the pattern? Wanna guess what the efficientcy is for a really stupid compiled version of this "benchmark"? A: really freaking low.

    I'll see about adding more thoughts later.

    There are two reason why this doesn't mean much. First, Apple may just cancel the accounts of anyone who tries to use PyMusique (that's covered by the iTunes Music Store Terms Of Service agreement). Second, it would be very easy to make this a violation of the DMCA (if it already isn't), all Apple would have to do is implement a "weak" encryption, like adding a zero to the start of the music stream and more zeros thereafter at 256 byte intervals. The DMCA doesn't say anything about how "good" the protection needs to be, so if anyone used a tool to strip those values they would be in violation of the DMCA.

    I suspect, in any case, that the iTunes Music Store doesn't broadcast the unprotected AAC file completely in the clear or as an uninterrupted stream of AAC data, so PyMusique may already violate the DMCA.

    The most important thing to note, however, is if you use PyMusique you may have your account cancelled (and Apple knows who you are and where you "live" based upon your credit card). So, if you really want to take that risk go ahead. And remember, you could also be found guilty of violating the DMCA even if you just try to use this tool. It's almost like you were planning of going online to one of the illegal music sharing sites, documenting your activities, and then sending that information directly to the RIAA with your name and address with a note asking them to prosecute. Basically, you're stupid to even try to use PyMusique.

    This is just a headline grabber or a means to raise the "fair use" banner.

    Edit: replaced reference to EULA with iTunes Music Store Terms Of Service.

    But EyeHome, Neuston MC500 and lots of others already do this. My EyeHome happily squirts anything on my Macs on to my TV or Hifi and lets me browse the web too.

    Why is iTV special?


    eyeHome does not support HD and it never will. I got this in an email directly from Elgato. That is the biggest difference. Also, the general consensus is that eyeHome is not in the same league of robustness/intuitiveness as other elgato products or Apple products. eyeHome cannot even play back eyeTV 500 , eyeTV Hybrid recordings.

    The trouble with DRM is that it often affects the average Joe consumer more than it hurts those it's intended to stop.

    CDs that don't play in a PC annoy Joe Public who buys a CD and wants to listen to it on his office PC while at work. The guy who planned on pirating it can easily get round the DRM and go on his merry way.

    DRM embedded in iTunes annoy Joe Public who burned a track onto his wedding video and now can't distribute it to the wedding guests without working out an authorise/deauthorise schedule.

    The record companies assume everyone is out to be a criminal while the 'criminals' don't bother buying DRMed files or strip out protection and do what they want so just as many files end up on P2P networks and on dodgy CDs on street corners.

    As per the typical anti-nuclear sentiment; much of these issues can be resolved rather easily. New reactor designs are far safer, and if you really want safety (as in you can't melt down, ever) then PBR or MSR with thorium is the way to go. Waste an issue? Shouldn't be-- the US needs to complete the fuel cycle with breeder reactors. Furthermore, spent fuel rods can be used locally for power via thermal couples-- this is how NASA powers most of it's spacecraft. As thermal couple efficiency increases, this will become a much more viable solution. If thorium is used (and it should be), the overall lifespan of the byproducts is greatly decreased, meaning waste is even less of an issue.

    oh the "thorium pebble bed is superiour" discussion ... i think over the years i had that one a dozen times(even on macrumors) ... a technology developed since the 60ties with spectacular failures regarding safe operation and economical total disasters for the german tax payers

    http://en.wikipedia.org/wiki/AVR_Reactor
    the AVR test reactor alone: construction costs adjusted for inflation did it cost 180 million euro... deconstruction + decommisioning 1 billion euro over the last 22 years (and still not finished)
    the highest contaminated facility regarding beta-radiation in the world

    There exists currently no dismantling method for the AVR vessel, but it is planned to develop some procedure during the next 60 years and to start with vessel dismantling at the end of the century

    that said the german government was still set on that reactor type and built actually a full scale power station:
    http://en.wikipedia.org/wiki/THTR-300
    -14 years to build, 3 years of operation
    -had a release of nuclear material just days after Chernobyl
    -bankrupted it's operational company, required a bail out
    -in 1997 was put into 'safe enclosure' until decommision can start in 2027 (costing 6.5 million euro per year until they can even start)


    thorium pebble bed reactors, the nuclear power plant for the future generations ... to clean up ;)

    By mainstream Catholic I mean someone who follows all the rules of the Catholic Church.


    Then I think you misunderstand what the word 'mainstream' means. The majority of Catholics do not care about the Vatican's line on birth control, for instance.

    The Public Religion Research Institute recently published a report based on a survey of Catholics across the United States. Amongst other findings:


    Catholics are more supportive of legal recognitions of same-sex relationships than members of any other Christian tradition and Americans overall. Nearly three-quarters of Catholics favor either allowing gay and lesbian people to marry (43%) or allowing them to form civil unions (31%). Only 22% of Catholics say there should be no legal recognition of a gay couple�s relationship.

    http://www.publicreligion.org/research/?id=509

    When same-sex marriage is defined explicitly as a civil marriage, support is dramatically higher among Catholics. If marriage for gay couples is defined as a civil marriage �like you get at city hall,� Catholic support for allowing gay couples to marry increases by 28 points, from 43% to 71%. A similar pattern exists in the general population, but the Catholic increase is more pronounced.


    A small minority of Catholics may support your views, but they would hardly be considered mainstream.

    this analogy is so stretched as to make no sense.

    but even water, there are residential rates and commercial rates... you can't mix the two .. there are limits and plans.

    you arent paying for the same data twice. you are trying to change the agreement after the fact.

    dont like the agreement. dont enter into it.Sir it is perfect.

    You are paying for the same thing.

    I have an unlimted plan

    and I never have gone over 5gb

    if one has a 2gb plan and never goes over and we both surf on the internet
    Tethering whats the difference?

    I have no idea why you can't understand Data=Data
    Water=Water
    both are pure
    the logic so you understand

    I drink water = use Data on the phone
    I pour water over my head = Data through tethering

    So its valid. Using the same amount of substance, what we pay for, to do things in different ways, what should not matter.

    Amount should be the issue not how I used it.

    even my 10 year old son LOL when we talked about this, he said he doesn't understand why you would pay twice for the same thing.

    Obviously it escapes you.

    SW engineers usually optimize their systems with expectations of the environment they will run in. Pro-level applications often run much better in systems that use SMP, but not all. Sometimes it is better to pipeline a few processes at high speed, rather than do a lot of task swapping. Most of Apples core customer's application seem to benefit from SMP. So, that is what they are going to expect from Pro-level hardware.

    Huntn, please show me some evidence for what you're saying. Then I'll tell you what I think of it. Meanwhile, I should admit that the Bible's original manuscripts no longer exist, and there are copyists' mistakes in the existing copies. There are mistranslations in at least some Bible translations. Take Matthew 24:24 in the King James Version. It's ungrammatical (http://www.biblegateway.com/passage/?search=Matthew%2024:24&version=KJV). But I still need you to give us some evidence that, for example, some tendentious ancient people tampered with Bible passages.

    I think you misunderstand what I am saying. While translations are very susceptible to being tampered with especially when a church hierarchy with an agenda is involved, that is not my primary focus. The focus is what validity do ancient scripts have as truth just because they exist? I may be able to give a possible example. Jesus is central to the New Testament, but according to a History Channel Show, there are no city records in the Middle East that confirm the existence of Christ. Is this fact or fiction? I don't know, but I have reason to wonder about it.

    I saw the Lourdes video and have to ask, has there been verified in any meaningful way? If so, there should be a substantial evidence, maybe a list of those who have been healed, hopefully with some documentation.

    As I said elsewhere there is no moral equivalence. It took Augustine's and Aquinas' great rambling treatises to justify warfare, for instance.

    In the Qur'an and the Hadith war is encouraged and its virtues extolled.

    I wish people would stop trying to equate the wars of Christianity (and of that mainly Western Christianity) with Islam's modern terrorism and calls for warfare against the infidel.

    In Islamic Law non-muslims are considered najiss, that means ritually impure, down to our souls, our essences. Christians are reviled especially because they practice "shirk", a law forbidding the joining of others to allah. Jews are designated as apes and pigs in the Qur'an.

    there is no equivalence between Islam and Christianity.

    I agree that today's radial Islam is dissimilar to modern Christianity, but Christianity has blood on his hands and is still involved in power and control although not to extent of blatantly murdering those with different views.

    That's pretty much my question too. The iTV is a mini without DVD, storage, OS, or advanced interface? I guess I just don't see a market for this at $300. Waste of time, unless I'm missing something.

    Well, it isn't "without storage", it has storage.

    It's fairly simple: it's a Set Top Box. It's another one, to add to your DVD player, cable box, and DVR. Well, I say "add to", but actually, you'll probably not need them. What is does is show whatever Quicktime will show that's accessable via iTunes.

    - That means anything on the iTunes Store
    - It means anything in your .Mac storage.
    - It means anything on your network, if you have one, that's exported via an iTunes Library.

    You'll go home after work, pick up the remote, and maybe you'll:

    - Buy a movie and watch it.
    - (Rent a movie and watch it, assuming Apple eventually supports the idea, or someone else finds a way to interface to it)
    - Watch a new episode of a TV show you subscribe to
    - Watch a free pilot of a show you're interested in.
    - Listen to a streamed radio station
    - Watch a subscribed-to video blog or browse other blogs, and watch them
    - Watch that highly amusing rip from "America's Funniest Videos" that your friend told you to watch, from Google Video, or other Google video clips.

    What will be available? Anything you want. As this becomes more and more popular, more and more content will become available. Expect CNN news to be just as available as episodes from ABC mini-serieses.

    How will you get it? Over your $25/month broadband connection. Which you'd have anyway for web and email.

    That's how you use it. For many people, cable, as a "just put on background noise and forget it" medium, will still rule. For others, such as myself, the prospect of TV built for me, rather than advertisers, is more compelling.

    I think it's awesome.

    I guess time will tell, but Apple needs to get something kickass out the door around WWDC. I think we have all been waiting for hte final piece in the puzzle: pro laptops - covered, consumer laptops - covered, consumer desktop - covered, pro desktops - waiting...

    Pro desktops are not quite the last piece of the puzzle! PowerMac replacements and xServes are all that are needed to make "the circle complete".

    The iBook, PowerBook, iMac, eMac and Mac mini have all had/have their Intel equivalents as we all know... here's to waiting! And like so many on these forums my CC is clear and ready to melt... ;)

    I wonder I they put a Xeon in a Mac will it come with Intergrated graphics :confused: ;)

    I sure hope Apple don't put intergrated graphics in the Mac Pros as ANY sort of an option......

    I guess they may install integrated graphic chipsets as an option for the 'new' range of xServes [although I'm guessing IG won't be an option - rather they're already there with option of over-riding them via a dedicated graphics card]; I'm obviously speculating and thinking along the lines that the majority of xServe installs are simply that 'installs' and not graphic workhorses, etc.

    Either way, the countdown to WWDC has begun...!! :D
