Probably the same way it is in scalable transactional databases that use multi-versioning concurrency protocols (e.g. PostgreSQL and Oracle). No data is over-written, and every "update" actually creates a new record version.
Lots of ways it COULD be implemented. Looks at Suns new file system ZFS. It is basically "Copy on Write". With a file system you can do things even fancier then with a DBMS. For example a "block" (i-node) exists physicaly on the disk only once but it could be maped into any numbr of files. If a file in only an orderd set of block numbers then to copy a copy all you need to copy is the set of numbers which is on the order of 1000 times shorter then the data itself.
But on the other hand you _want_ the data to be physically copied if it is to be backed up to an external drive.
Some time ago Apple was talking with Sun about using ZFS in OSX but I don't think anything came out of it. I suspect Apple wrote this themselves
The problem is not that I can't figure out how Apple did this but that I can think of about a half dozen ways they could have done this.

Let's be frank...
Whether totally Radio Shack's fault or
not this was a very sloppy launch for the
company.
Quite frankly, I think they were just given
the ******** end of the stick by Apple who
obviously is throwing them whatever leftovers
they have which now must be distributed
across all their stores.
I'm stuck. This phone is costing me $650
and I will not spend that kind of money without
getting $200 off on my trade-in. So I am
sitting here just waiting it out. It may work
out well for me because I may luck out on a
White iPhone by the time my store gets stock.

The thing I like least about this rumor is that it specifies only a 320GB harddrive.
The current configs (quad g5) were released in October of last year, in that time harddrive capacities have increased well beyond that (320) small number.
The new machines will get 500GB drives I have to believe.
:confused:
320 would be the standard. you could upgrade to a terabyte if there are still two HDD bays.

So many things that FCP / FCS can improve upon here - they need the equivalent of Adobe's Mercury Engine, leveraging Grand Central, QTX, and a full Cocoa build for all the FCS apps...
At present we have to re-encode a lot of our footage (7D / Minicam etc), and you don't need to do that in Premiere, it just plays on the timeline - however editing in that is quite frankly an exercise in sheer frustration and strange bugs.
Come on, please be true! The days of pressing CMD+R I would love to see over! Especially when you are rendering an audio effect that actual renders in a microsecond, yet won't play realtime... Sigh.
Personally, I love CS5, even on the Mac Pro with 5870/GTX285. Hopefully this won't jinx myself, but I've had no bugs or frustrations, and I edit full HD movies with it.
I'm looking forward to this version of FCS, because I've only played around in it with others' systems, and it didn't blow my skirt up. It will be nice to have both suites, if the new FCS proves worthy. I know a lot of FCS users, and I look forward to joining them, so get this thing right, Apple.

Actually, the merom in not completely compatible with the yonah chips. There will have to be some redesign on Apple's part that is supposed to delay the new MBPs. This article somewhat explains it:
http://blogs.zdnet.com/Apple/?p=249
Also, since Apple is now kind of competeing with PCs who get the newest and fastest, it would be in Apple's best interest to get these chips in MBPs asap. Also, it is easy to see that a lot of people are waiting to purchase a new Apple laptop with this technology. MBP's current sales are going to slump from here on out until this technology is put into some new computers.WRYYYYYY!!!
Looks like I'm going with a tower or iMac for school then.

I don't want anyone to attack anyone else. Whomever calls names, name-calling is libel or slander. I say, "Attack ideas, not people."
Not if its true. So saying "Palin is a tax lower lowering nut" can be true. Its up for debate, but you can make the argument based off factual arguments.
Doesn't mean its a good idea or helpful to the nation, but its not libel/slander if its true.
I I wasn't talking about liberals in general. I said that most of the name-callers I knew of were liberals.
But its clear what you are implying

I still think it's funny that everyone thinks these Macbook Pros are "long overdue" - when, exactly, did the FIRST Dell laptop with C2D ship? I thought it was supposed to be around tomorrow...but surely it couldn't have been before last Monday or so at the earliest.
So that's, what? A week behind in the worst case scenario? Oh God...
However - if they waited till November, then yeah, I'd agree that they were overdue...:)

I LOL'd. I owned iPad 1 for a year, and while it's nice, it's a FAR, FAR cry from the productivity capabilities of the current gen MBA.
Like it or not, iPad is SEVERELY CRIPPLED for content creation (i.e. real work), but excels at content CONSUMPTION. That's factual and completely undebatable. Everyone knows this.
So, no, it's not "something better". It's a more viable choice for entertainment and consumption. That's it.
I didn't say I use it for content creation or production capabilities. Desktop power. Screen real estate. I'll take my iMac with 24" screen over a notebook at 11.6 or 13.3. And my graphics and cpu power over that in an MBA. And when I want something instant on, and quick access, and light and mobile, I've got an iPad 2. Sorry, but read the whole post. I apologize if I'm not one of those people who kids themselves into thinking that a notebook is a viable "real work" machine.

...Why in anybody's right mind would best buy not sell what they have?
This may have already been said. But some stores will hold onto stock of a hot selling item because it will be posted in a weekly newspaper ad.:cool:
So, if they have the hot selling item at the time (in this case, iPad 2) on a Wednesday or Thursday and aren't getting any shipments until the next week but have an upcoming Sunday flyer featuring that item, they will hold the item in the back until Sunday. They don't want to be sold out before they open on the day the item is advertised in the paper.:eek:
So weird that in 2011 stores selling the latest electronics care about newspapers.:rolleyes:

Apple could start improving their customer service by:
- Combining "Pro Care," and ".Mac"
- Offering online apple care support for .mac members
- Extending their standard warranty
- The ability to serve people at the apple store as they walk in (for minor issues). Who in the world came up with this appointment crap?:confused:
- Allowing apple users to subsrcibe to apple learning events in iCal.

Google's "openness" reminds me of the days when people got all excited about being able to use different fonts and font sizes... sure it is exciting to see the possibilities and to be able to "customize" your documents, etc., but in the end, you only end up using a hand full of them (despite thousands of them being available), and most of what is being used is STILL what was the default choices back then.
Just like a kid that thinks they're going to be greater and better than those older than them because they know better; well, surprise, surprise... Google has turned out to be worse than IBM or Microsoft or Apple ever was. The deal with them will just keep getting worse and worse until people come up with genuine alternatives to their constant lying and deceptiveness (oh, yes, picking up 10M wi-fi SSIDs was purely accidental...).
I don't blame them for having to switch gears on this... I blame them for not being able to see 5 mins in front of their face on this issue (like so many other things) and insisting that "they're" correct every time it is obvious to everyone outside their company that they're not...

Man do these stories bring out the ignoranus fanboys. IMO if you have never owned both an Android phone and an iPhone, you shouldn't be allowed to comment because 99% just can't be objective about it.
Now, I'll hop on my pedestal and say I owned the original Moto Droid, and now own an iPhone. The ability to customize your experience on a droid is what I found so attractive, and Google isn't taking that away, so IMO this story is nothing but good for Android. Better control, more polish, yet the same customization capability that the majority of everyday users want. All of the iBoys tooting their horns and patting each other are doing so for absolutely no reason.
With that said, the polish of the iPhone is what I love the most about it, and if I could pair that polish with Androids ability for personalization of my device without jailbreaking and their much superior notification system, it would be the perfect phone. The next device to get it all right gets my money, whether its apple or Google.

It's amazing how Apple keeps managing BIG updates to OS X. They are moving forward so much more efficiently than Microsoft. Not just polishing little things, but big, useful things. Not to mention some fun ones to attract consumers. I hope the advanced Spotlight features include easy boolean searching.
And now we can all wonder about those OTHER features Steve said they are concealing for now so Microsoft can't make a halfway copy (or attempt to) yet again.
I'm surprised res-independent UI was not discussed, but Apple has already said (http://developer.apple.com/releasenotes/GraphicsImaging/ResolutionIndependentUI.html) that is coming, so maybe it's just not polished enough to bother showing yet. (Or maybe it's better to show when new displays come out? Today's new low prices on Cinema Displays might hint at new displays to come later.)
I've been asking for that background-change effect in iChat for years! Adobe Premiere could do that in the 90s, though not in realtime. Too cool!
Now one question... A new Front Row has been mentioned, but what will it have? PVR, tuner-ready for future Macs or peripherals? At first I also wondered about ["from across the room or across the house"... But I bet they're just talking about sharing iTunes or photos from another Mac, which is old news.
PS, congrats to MR's servers for handling the load :)

I have to say that I think a lot of people have missed the point around various software not using all the cores. There is a simple reason. Developing multi threaded apps is hard. And until recently (~1 yr since G5 Quad) developing for more than 2 simultaneous threads (cores or processors) was pretty pointless on a Mac and completely pointless on a PC. Why would a developer bother to develop for more than two thread unless they expect threads to get blocked easily or there to be more than two cores? That's why browsers are one of the few genuine multithreaded apps, rather than 2-4 threads, the threads block easily, so having multiple makes sense. In a lot of cases where there was the opportunity for parallelism using a vector processing unit often makes more sense than multiple threads. Why spend development and testing effort on a solution with no hardware to even test it on, let alone deliver and make use of?
The whole industry is taking a 90 degree turn and the tools for developing multithreaded applications are not up to scratch. Look at some of the commentary about XBox 360 and PS3 development.
The dev tools will come, the software will catch up with the hardware, in the meantime just be glad that you can play your stolen MP3's and browse your pr0n without interfering with each other and stop whinging.

Intel is supposed to start shipping Clovertown CPUs into the retail channel by mid-november. We should see systems based on them by then too -- HP is claiming to have their first Clovertown workstations available on the 15th, so only a month away. I bet we'll see the 8-core Mac Pro systems by the end of November.
