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.

Can we officially call this an over reaction? I'm all for Apple explaining what is going on here but a lawsuit is overkill. Where is the proof that this is actually harming people?

Do these stores you guys are talking about actually have the iPhone in stock already?!?! Cause I just called the two closest ones near me and they still aren't sure if they will receive any for thursday
Yes Brandon they received them in store today. My buddy was able to grab two from the local store that did not generate any PINs so I will be getting mine Thursday morning now. Radio Shack is also giving $20 Gift Cards to use towards accessories at the time of purchase in this area.

I wouldn't worry. I have an insider source who assures me Apple is basing its entire iPhone 5 product launch on when your contract ends. Here's a direct quote from Steve Jobs:
"While the antenna issues forced us to accelerate our product cycle in favor of a redesign a year earlier than expected, and while the earthquake/tsunami disaster in Japan has added several of its own complications, rest assured that Apple will take every conceivable measure to ensure that the iPhone 5 ships at a time close to the end of mlmathews' 3Gs contract. We have been quite fortunate with the success of out iOS devices in recent years, but we're not about to start pushing our luck here."
You're right.
I have confirmation that the upcoming iPhone release date is Tuesday January 17, 2012.

i talked to a friend of mine thats a GM of a bestbuy store. He or his regional manager didnt know why or who put the stop sell order
on the ipads this morning. At 6pm they still didnt know why.
The email only said dont sell new in the box ipad 2s, sell through
your preorders and open items. no other instructions
were given. i think they over sold there preorders at some locations.

Intel isn't forcing anything. Mac Book pro's are using Sandy Bridge AND have a separate graphics chipset. :rolleyes:
Again, let me be a broken record :
Intel forced nVidia out of the chipset business, making the choice of IGPs for OEMs be Intel or Intel. Now we're back to square one, where IGP = suck. When nVidia made IGPs, at least they made half-decent ones.
The 320m is an IGP, same as the Intel stuff. Except it doesn't suck.

i believe samsung manufactures a lot of their own hardware.. from the display panels to the chips. don't they provide apple with parts for the ipad too? i think this is how samsung is able to price match apple here
samsung designs and builds stuff in factories they OWN. Not all of their manufacturing is outsourced, unlike apple. Yes samsung provides ram, LCD (?), and A5 for apple's ipad. It was rumored that TSMC would also make A5 for apple so that apple is not so dependent on samsung but from what I saw in teardowns, samsung is still making some, if not all, of A5.

The problem with your "logic" is that not everybody is gay. Homosexuality is nothing new, gay people have been around for a long time, and humanity is surviving.

I don't know how many times we have to go round and round with this here. I've been on MacRumors since '01 and it's always the same-old, same-old. It's not legitimate. It's "I-wantism." You have no basis to believe that a Rev B would be more "stabled and refined." That's a hope, backed by nothing -- and nothing Apple ever comments on, either. The bottom line is that you can hope if you want, and you can wait if you want, but to bash Apple for being slow on the trigger, and to make the argument that Meroms are amazing and Yonahs are crap is, frankly, horse manure. Like I said, 64 bit is pretty irrelevant for most users, and the speed and battery differences are quite negligible. And the argument that Apple is losing tons of sales to PC manufactuers is, frankly, laughable too.
Then please let those in here, myself included, make our own mistakes by buying the lastest iteration of the macbook pro. 'kay, thanks.
This isn't a "why are you waiting for rev-X." This is a thread about notebook refreshes and when they're going to happen.
That being said, I'm now waiting for Photokina. :)

They will not replace the dual core version, they will exist as an additional product offering.
I never said otherwise. My point is they are the follow-ups to conroe and woodcrest and will use the same sockets as those two. Which means they can be swapped in, which I believe was the original question.

What are fivepoint and MattSepeta arguing about? Obama has not lied or invaded a country for no reason. This is a coordinated effort agreed upon with the UN. Huge difference. Just because people are liberal does not make them opposed to all military action.
I supported Bush's invasion of Afghanistan.

Are you spending as much on music as you did years ago?
Definitely not! Because a lot of music is pure crap. Simple. I'm not spending $1 on music I don't like.
Dump the manufactured bands and the quality may rise again.
Universal already get payments from blank CDs et al - there is no need for them to start getting payments per iPod sold. Pure utter greed.
Apple could argue by having the iPod on sale, it is Apple who are in fact driving music sales. However, I would NOT like Apple to start having a cut of music company profits. That would be wrong too.

I really think Apple will be brining out a great product here. They have had a lot of time to hear what people want and don't want. I'm being very optimistic, sure no one will get everything they want since that never happens but will get great things (I hope!).
My only problem is I'm in the market for a new camera and want to make sure I know what's up with FCP before I get my camera mainly because I don't want to wait for any updates for the camera I decide to buy since it won't be VERY high end.
Can't wait to hear this news.

If this is a standard $129 upgrade I don't see anything here worth that price sadly. That is unless somehow my 2009 mac pro will run 2x as fast but I am not keeping my fingers crossed.

The thing that perplexes me is the relocation of the Power Supply to the top. This is either bogus info or they know something they aren't letting on about all the Liquid Cooling problems that have been arising lately in the repair world.
Plus would this not put a strain on the power cord since the cord would have its own weight hanging down on it instead of how it currently comes out of the back of the tower and immediately lays on the floor or desk surface? Something's fishy about this.
what if the plug is still at the bottom, and the connection to the actual power unit is internal? high voltage connection through the case innards - is that possible ?

I'm a little confused by introducing *both* 8.9" and 10.1" Tabs - exactly what's the point of splitting the market like that for a $30 price difference? Are they seriously expecting retailers to stock two nigh-identical devices?

Its tough, but i did it. Unless you are going to hit someone you really dont need to slow down for many turns. The buses dont go fast enough for it to be a problem. You can get to 11th at the first turn but cutting in very close to the cone (dont hit it!) and downshifting to slide a little. Sneak into 11th and start drafting the bus in front of you. Theres an easy left where you can pass on the inside and take one more place, then get as close to the tires on the right as possible and you'll be able to grab a few more spots before you hit the 2nd straight.
The next turn is a hard left into an easy 180� right. Be careful on the left as its easy to hit a cone, then cut close to the inside of the right. When you get out of that turn you should be directly behind the blue and teal buses. You wont be able to pass them for a while so draft as best as you can until you get to the hard left at the complete other end of the track. Take that turn really wide and stay to the inside as you exit. You should be able to stay at speed and sneak right by if you are careful enough to not bump into them. If you are too close just back off a little, as long as you pass the blue buses at this turn you are doing great. Just be careful.
The next is a hard left that takes you back to the starting line. If you got ahead of the blue and teal bus there will be a bit of congestion there. Stay close to the inside but be careful you dont hit the grass too much. You should be able to get 5th or 6th before the 2nd lap starts. Follow the same lines as before and watch your corners for a chance to pass on the inside. I got to 1st at the last long straight, but the dark green bus in front is a little violent, so screw the line and do whatever it takes to stay away from him. Take both last lefts carefully and you'll grab first.
Its tough, but possible when you learn the track. I havent tried the Lotus challenge yet because i've been working on licenses, but i assume its roughly the same process just much faster.
Cool thanks. I will give this a try. Anything to get this bus done. I hate the tasks where whatever it is you are driving is real slow!
