I think this program is great. It will make it a lot more convenient for people to play their music anywhere they like. DRM is one of the reasons (in addition the the crummy AAC format) I don't buy music from the iTunes music store. I like being able to play my music where *I* want; I don't want Apple/RIAA putting any restrictions on that.

They run at a slower clock speed than the dual cores.2.66GHz is not slower.So if you have a very well multi-threaded app or are running lots of apps at the same time, having 8 cores might help. But otherwise you're probably better off having less but higher speed cores.
The difference between 1 and 2 cores is sizable, between 2 and 4 is decent, but as you up the number of cores you get a diminishing return because the software has to be written that much better to take advantage of it effectively. It's not like the old days where in 18 months, your system's speed effectively doubled because the clockrate double making any one process run twice as fast no matter how badly written it was.I am astounded by those who drop in here not understanding this technology at all. Read the thread then get back to us. Do you even understand the term Multi-Threaded Workload?
Oh and welcome to MacRumors. ;) :p :D

From Cult of Mac's blog (http://blog.wired.com/cultofmac/) on the issue:
I have now had the chance to read through Greenpeace's "Guide to Greener Electronics," and there are a few things that should be clarified about where Apple ranks.
First of all, the article I linked this morning claimed that Apple and Lenovo were at the bottom of the charts. Well, that's not true. Lenovo scored an appalling 1.3 out of 10 while Apple pulled a marginally more successful 2.7 out of 10. In between were Motorola and Acer.
The criticisms of Apple are fair, I would say, though I think there's some nuance to what HP is doing with recycling that tends to make it look unfavorably better than others. Why? Ink cartridges and printers. HP has a lot more to take back than any other company, so their commitment to percentage of sales taken back is actually a possibility.
Given that Apple actually offers free computer recycling with the purchase of a computer, something that Dell does but HP does not, it's odd to say they're doing less to keep computers out of the waste stream. On the other hand, Apple has no takeback goals, so it really does balance out.
The other criticisms of Apple are on target, however. The company is secretive, and that meets they tend to be secretive about their environmental planning as well. They have a regulated substances list, but it isn't public. They're committed to eliminating PVCs, but won't say when. Ditto for BFRs.
It's not necessarily that Apple's environmental record is legitimately bad, but they do a very poor job of informing their customers about their environmental efforts. Silence is suspicious here, folks.

Since the 2.33GHz Clovertown processors are priced the same as the 3GHz Woodcrests - $851, I think it's fair to say the current 3GHz Quad Core Mac Pro costs about $825 per core while the 8-core 2.33GHz Dual Clovertown Mac Pros will cost only about $412.50 per core. That looks like real progress to me. On the GHz front, the current one running @ 12GHz is about $275 per GHz of power while the 8-core running @ 18.64GHz is about $177 per GHz of power. That looks like real progress as well. :)

You can break that law as a form of protest if you like, but, as eric_n_dfw says, the way to do that is by making your lawbreaking public, to be willing to accept the consequences of the lawbreaking, and thus work within the system.
By living in this country I am bound by its laws. Period, full stop. Why is protest only allowed if you make it public and go to jail? The most public display of protest I am aware of is the 50+% of people who do not vote in any election. You might think their protest is foolish, but by not participating in the sham they speak volumes for those who listen.
Likewise, the BILLIONS of songs "stolen" vs. purchased on iTMS speaks volumes about people's feeling about DRM, RIAA, and these laws you speak so highly of. It is like "terrorism", it is 100% dependent on what side of the argument you are on. The USA has directly killed far more people than these so-called terrorists. Many who are on the side of the USA do not see this. This does not make those who disagree with the USA supporters of "terror", it simply means they disagree with the logic - and laws - of the USA.
Breaking DRM is no different. If you agree with the laws you speak of how important it is to follow them. If you don't agree you justify your actions in a myriad of way. Everyone is subject to the "law" however just or unjust the law may be.

1 iPhone Model (3 capacities) on AT&T vs many different Android Phones on all the other providers...
Seems possible to me...
(I can see a FREE Android Touchscreen phone with unlimited voice, data, and text for $70/month from someone out there to try to beat AT&T's offering - which isn't very hard to do...:eek:)

Wow, a TON OF YOU totally miss the iTV purpose, to stream content FROM YOUR MAC! That's why no tuner, no storage, no anything!! Does Airport Express have storage, an antenna, etc?!? NO!!!
I love this! I want one today! I'm going to get a huge HD, maybe two of them and start my stored media collection on my G5 that I can wirelessly access in my HT room from the iTV's wireless remote!! I love it!! Music, Family photos in a slide show, eyegato to record HD programs!! Awesome!!!
This so rocks and will make a ton of money for Apple! I can't wait, this is truly what I've been looking for as there's no HDMI out on my G5!!

AT&T already gets $50 I'll be damned if I pay anymore for the 1 time a month I actuly need to pull up a full web page due to flash. Yes they get $50 for data, $30 for my unlimited plan (I use ~1gb) and $20 for unlimited texts which is simply insanely small amounts of data.
What contract did I physically sigm when I got my phone? The only thing I signed was a credit card receipt. All you idiots need to read up about Ma Bell and the **** they tried pulling years ago. It's headed back in that direction now.
To all the morons who say if you don't like it don't get it. Your right the carriers should rule over ours lives. We should simply not have phones if we don't want to grab our ankles and like it, every time the phone companies come up with a new way to stick it to us.
Weak minds will continue to be brainwashed by larger corporations site any TOS you want. Your the same people that argued about how AT&T needed 2 years to get MMS to work, and they were right. Probably the same lot that gladly ponied up extra cash to unclock Bluetooth and ringtones on your celluar one / vzn phones.

Option 3; STOP trying to cheat the system, and START using your iDevice the way the manufacturer designed it and the way your carrier supports it. (Is it unfair? YES! Are all of us iPhone users getting hosed, even though there's now two carriers? YES)
And while you're at it, knock off the piracy with the napster/limewire/torrent crap.
(Yeah, I said it! SOMEBODY had to!)
You do realize the phone, aka the system, was designed to do this and that AT&T is going out of their way to charge people double for what they are paying for?
It would be no different if your home ISP tacked on a $20+ charge each month for having a router at home.
I'm waiting for the class action lawsuit as this is wrong. The service that people have bought is not somehow giving them more bandwidth or a higher amount of download data simply because they are tethering through the phone. The phone can only download so fast to begin with so any device you connect to it will still be limited.

Fine, so I can write an installer that will just wipe your user account while you read my EULA and you'll happily execute it because "hey, it's just an installer" ? :rolleyes:
Is anybody actually bothering to do this in the wild against any OS?
This is not, but I'm interested in the mechanics because next time, it could very well be. That's my point. Some of you guys aren't cut out for computer security...
The types of attacks you are referring to are not occurring in the wild on a massive scale. When was the last time you heard about one in the media?
At the moment, there is no way to prevent the kinds of attacks you are referring to on any OS if a vulnerability exists that allows the attacker to exploit a running application.
Webkit2 will reduce access to user space when Safari (or any app using webkit2) is exploited by restricting the privileges of apps on a per app basis.
Turn off "Open safe files after downloading" if you are worried about that type of attack implemented via "safe" files.

I do agree that it is effectively the break of a promise. Hell, it's the breaking of a contract... which is certainly quite wrong. But what if you believe the original terms and conditions to be morally wrong in themselves?
If you believe the original terms are morally wrong, then you should never agree to abide by them. Once you choose to agree to the terms, then you are morally bound to abide by them.

Clovertons to run hot until 2007 according to:
http://www.reghardware.co.uk/2006/11/01/intel_fwives_core/Oops! This makes me change my mind about buying this Fall:
"HP, and other OEMs, should have Clovertown gear ready on the 14th. Our sources inside HP say the chip is eating between 140 watts and 150 watts..." :eek:
"Intel hopes to deliver less power hungry parts in short order. CEO Paul Otellini has talked about 50W and 80W Clovertown parts set for the early part of 2007 (http://www.reghardware.co.uk/2006/09/26/intel_quad-core_roadmap/)." :)
Guess I'm gonna have to be a little more patient a little longer in that case. That will be after MacWorld Expo toward the end of January then. Oh well. So much for immediate gratification. ;) Looks like waiting for the 8-core to ship with Leopard will jive with the cooler less power hungry monsters as well.
Thanks for bursting my bubble. :( I can get back to the business of another longer term wait similar to the wait for Santa Rosa or the mobile C2D MBP that's shipping now after 10 months of mobile CDs. At least it won't be that much longer. :cool: Looks like Clovertown Rev. B will be worth waiting for as well.
My apologies to all who were negatively infected by my extreeme enthusiasm for the first Clovertown release before I understood this new information. I can wait. I know some of you can't.
And I also may change my mind again when/if Apple releases a hot version first. Maybe they'll pass on the 150 watt models. Or perhaps they have real good cooling figured out. But I think I'd rather be ecological and buy what consumes less power anyway - especially in light of only another 2-3 months time.

I have a question for you:
Why does the Motorola G4 do so poorly in SPEC, while:
The MIPS R12000 & R14000,
The Intel Pentium III, 4 & Celeron,
The AMD Athlon,
The HP/Compaq PA-RISC,
The HP/Compaq Alpha,
The Sun SPARC,
The IBM Power3 & Power4,
all thoroughly trounce it? Only the Athlon and Pentium are x86 compatible. The MIPS R12000 only runs at 500MHz and it still kicks the snot out of the 1GHz G4. Why is that? Honestly, you don't believe Apple is at the mercy of a vast conspiracy which is the plot of SPEC and the processor manufacturers, do you?
When RC5 and Genentech tests prove that raw performance the G4 is much faster than the Pentium IV or AMD, which it does, then it basically throws out the whole idea that Mhz matters. The G4 is 4 to 5 times faster.
At certain highly specialized tasks, yes. Because these are two of the very few tasks which are ABLE with ANY amount of tweaking to perform well on the G4.
As for hand optimizing code, you don't have to do it. What you do have to do is write developers of your software if you are displeased with how poorly they optimize code, or go seek better written software.
Great idea.
Dear Microsoft,
I am displeased with the performance of Word v.X on my Mac (PowerBook G4 667). The cursor always seems to lag, and the application doesn't respond nearly as quickly as it does on my similar PC notebook. Could you like, fix this? Throw a little AltiVec in there, couldn't cost you more than $50,000.
Thanks,

As for other factors which influence speed, let's look at the internet browsing which people constantly harp about being slower on a Mac than a PC. My 768/128 DSL on my G4/800 Flat Panel iMac is easily 5 times faster browsing webpages than my T-3 based Windows 2000 Pentium III 1 Ghz machine. I wait and wait on this Pentium III. Goes to show you processor isn't everything.
So your argument has changed from "the G4 isn't slow" to "processor isn't everything anyway?"
It is in software, and until people realize it is in the software, complaining about hardware is not going to matter a hill of beans.
Of course "it is in the software." "It" is also in the hardware. "It" is in both. Apple needs faster software. They have been improving in that area. They need faster hardware as well. They have not been improving nearly as much as they need to be in that area.
64 bit processors are so slow to be developed because so few people have made their software optimized for 64 bit operations. If people need it, they'll get it. For 99% of computer use processor speed of machines nowadays is more than adequate both on PC and the Mac. Adding peripherals though is much easier on the Mac, and installing and removing software still is much easier on the Mac without causing a crash. And ease also means less time spent. So what does speed of the machine have to do with productivity when machines like PCs are so hard to manage? Nothing! Because when it is easier, it takes less time. That's the Mac advantage.
Finally, something you said that I agree with!

The one that I use doesn't work with the Macintosh, but apparently, the PCIe/SATAII version of the one that Eld is talking about will as mine uses no SATA interface for data transfer.

NB. I guess the most critical things that can get damaged in Japan are the nuke power stations, the reports so far say none are leaking.
I wouldn't worry about those. They're incredibly well designed. If Japan has any of the new AP1000's, then there's really nothing to worry about.

The only reason I could see this happening is if Apple doesn't roll out the iPhone to other carriers or if it does so late in 2011 or something.
I could also see Google making more unit sales but with lower revenue (i.e. more low-end units).
I think the point will be moot because of the gazillion different iterations of hardware manufacturers tacking on their individualized stuff.

I did a little reading and now am a one minute expert... :p
I've read these reactors did auto shut down when the earthquake hit. The problem is that the rods create tremendous persistent heat even after a shutdown, and it is the lack of cooling water that is causing the problem.
Could it be considered a myth that any nuclear reactor can be expected to automatically safely shutdown when power to all safety systems are lost no matter how it is designed?
And who was saying this could not be like Chernobyl??
Modern plants use passive removal systems in the event of reactor instability and they are much safer as a result. The Fukushima reactors date from the 60's so the decay heat removal mechanisms are active, employing pumps instead of heat removal via natural circulation in the event of a failure, hence older plants do present more of a risk in this sense than modern ones.
Ah, but once again it's all about location, location, location, and they don't have any viable sites for safe nuclear energy, if such a thing exists.
That's true, but I suspect a modern plant employing passive safety mechanisms would fare a lot better in the same scenario.
Still, ifs and ands... Sincerely hope they manage to get it under control. Just been another fire I see on the BBC News site.

Ah, but once again it's all about location, location, location, and they don't have any viable sites for safe nuclear energy, if such a thing exists.
That's true, but I suspect a modern plant employing passive safety mechanisms would fare a lot better in the same scenario.
Still, ifs and ands... Sincerely hope they manage to get it under control. Just been another fire I see on the BBC News site.

Maybe someone has mentioned this, but I find it extremely ironic that Greenpeace is hitting up Apple, where none other than Al Gore is on the board!! Can Apple really be that bad? (oh, they were 4th worst out of about 20 companies.) So, either Al Gore doesn't put his money where his mouth is, or Greenpeace is just trying further its anti-corporate agenda. Maybe both???

So this is basically a jazzed up Final Cut Express and the pros have been shown the door. Why am I not shocked about this. :mad:
Someday I'll tell my kids that Apple was the company for pros to which they will laugh in disbelief; kind of how I do now when old people tell me that American cars were once high quality.

On other forums, people complain about the word agnostic.
>agnostic theist- I believe in god, but have no knowledge of him.
>agnostic atheist- I don't belief in god, but I don't claim a special source of knowledge for that disbelief
>gnostic theist-I know that is a god!
>gnostic atheist-I know there is no god with the same degree of certainty that the theist knows there is one.
I don't think that many would call themselves a gnostic atheist, I certainly don't.

Looks like Apple made it easier to use and the so-called "Pros" feel threatened by that because it takes less specialized knowledge to do impressive work. We might not be there yet, but in time even grandma can edit. You get the point.
Part of the reason established IT folk feel so threatened by Apple.
You're incorrect... well... at least I think you are.
I have yet to meet a professional in this field that resists products getting easier to use. But what professionals hate are changes so drastic that 1) there's a learning curve, thus slowing them down, preventing them to make a living and 2) removing features that significantly change the workflow that allow them to work quickly and creatively.
Number 2 is my biggest worry. A complete rewrite is great. 64 bit is great. Grand Central is great. Multi-Core is great. What isn't great is the potential loss of features. Even the littlest feature, that most people would find mundane, could be very important to editors who've become used to that feature being in their workflow.
I work in broadcast/cable news where editors have to turn packages around quickly. You remove features that prevent them to work quickly because it altered their workflow... well now you're in trouble.
I can buy the excuse "Well they'll add it in version 2" if we're talking about consumer programs like iMovie. iMovie is not "mission critical."
But that feature that existed in the old-world FCP versions MUST be in X from day one, IMO, or else Apple will face a steep uphill battle to win FCP editors back.
