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.
Ahem, a modern relational database system can do everything a file system can. In fact, they are both databases, but optimized for different tasks and slightly different semantics. The same behaviors can be achieved with both; it is a matter of design bias, not capability. File systems like ZFS actually converge on normal MVCC database behavior, which durably journals all writes but with more flexibility with respect to atomicity and version cleanup than a file system. File system semantics, even versioning ones, are more primitive and less capable than database ones, but with substantially increased performance over what would be possible from an MVCC database for the same task.
Same theory, different optimizations. The balancing act has always been between the power fully ACID-compliant MVCC semantics and the basic speed of simple file system semantics. Apple and Sun are burning some excess performance capacity to deliver features that are closer to the database ideal.

My Predictions:
Mac Pro:
-Fastest pro Mac ever shipped
-Hard drives, BTO 750gb, perpendicular recording
-New displays with HDMI, iSight & IR, even brighter
-Wireless-WiMax or 802.11n-whatever's ready first, otherwise BT 2.0+EDR, AE
-Multiple graphics card in a SLI/Crossfire like mode for extremely powerful graphics and stereo 3D, Quadro FX5500 and maybe also first Mac to be supported by the new Quadro Plex. 256MB std, 512MB BTO
-HD Audio
Isight on displays built-in but I only want that with higher resolution with Auto Focus ability.
> New displays with a thinner bezel around the LCD; higher contrast ratio 1200:1 minimum; denser pixel count, DLP technology with LEDs or with Zenon technology for the DLP; but more richer BLACK!
> BTO Bluetooth 2.0+EDR has been on the PowerBooks for at least 2 generations & on the MB+MBP!
> WiMax although sweet its long away; HUGE battery gobbler. 2 years minimum.
> I'd love for the MacBookPRO lineup to be more PRO with DUAL HDD configuration but without creating more heat.
> THe MBP should be equal in computing & graphical performance as the cheapest MacPro!

feel free to point out how difficult it is to see any similarities...
You're talking about the Trademark claims for the icons, which as I've pointed out in the other thread, Apple must pursue. I've never made any claims as far as the validity or lack thereof of this claim over the icons.
My point was about the trade dress claims about the device, specifically, the screen bevel, shape of the phone, position of buttons, "icon grid". Again, not all models of Galaxy S seem to be infringing on the iPhone and thus it is quite bizarre that Apple is including all them in their claims, and also quite handy that the Apple biased media is only using pictures showing the "similar" models.
The particular model I posted does not look anything like an iPhone.
Feel free to discuss the same things I am next time so that we can actually have a meaningful debate about it.

Clovertown is a 64-bit CPU.
Ask your PC-loving IT guy if he uses Windows XP64 and more than 4 gigabytes of RAM. If not, then 32-bit processors are apparently okay for him, too.
hee hee - thanks.

.... Introduction of world's first commercial 8-core system.
Not quite the first. Sun has been shipping a commercial 8-core systems for about a year now. The T2000 has all 8 cores on one chip but each core also does four-way hyper threading so they claim 32 hardware threads. The price for an 8-core T1000 is about $8K. A system with 8 cores and 8GB RAM burns about 250W
Of course it does not run OS X but Gnome on Solaris has a very OS X -like "feel" to it.

Was there any doubt it wouldn't be a lot faster? I mean, I know it was already plenty fast, but come on...
But it's not faster. Slower actually than the G5 at some apps. What's everyone looking at anyway? I'm pretty unimpressed. Other than Adobe's usage of cache (AE is a cache lover and will use all of it, hence the faster performance).
But the actual xeon processors are only as fast as the G5 processors. Look at the average specs... the 2.66 machines are only a teeny bit faster than the G5s except in a few apps like filemaker. But not in the biggies like Final Cut Pro where it actually appears that mhz for mhz the G5 is a faster machine hands down!

It's nice for Apple to have high iPad2 sales, and I think that's great. It's too bad the Xoom isn't selling more, although 100k isn't too terrible right out of the gate.
I've seen and hefted a Xoom, and you know what? It's a pretty decent piece of gear. Good job Moto! From a hardware perspective I liked it every bit as much as the iPad2. In my opinion, its only downfall is Android. For me, Android is not intuitive at all. I can deal with that when it comes to traditional computers, but I don't have time to waste with that sort of nonsense on an appliance - I want it to just work, and that's what Apple provides.

Oracle's acquisition of Sun was just... bad. I have nothing good to say about that.
I loved ReiserFS (v3 anyway). I was using it in beta on Slackware about as early as I could.
And for my unnecessary griping about HFS+, I've never had a problem with it the whole time I've used Macs (so, about 6 years now). ZFS would be cool though.
I'm not sure about that .. my hfs+ partitions always seem to get corrupted more often than any linux box i've ever owned. I hate to say it, but probably even more than any windows box i've owned.

I'm not a birther. But I would love to know why the certificate looks new when the president is nearly 50. Now I'm about five months older than he, my original birth certificate has faded. The certificate he produced clearly isn't the original. Or if it is the original, it's astoundingly well-preserved.

My apologies to the"greens", but these tablets ( and my ipad) will NEVER be a true enterprise product with out some sort of native printing and a FIRST CLASS STYLUS/WRITING APPS. PERIOD.
I use mine in two different business, but it takes drop box, print work-arounds and crude writing apps to use it for business.
I enjoy it for all the other reasosns, but business goes to my MAC AIR.

This is ridiculous. The record companies are obsessed with money. They didnt seek royalties on CD players but iPods are somehow different. They are MUSIC PLAYERS. They record industry should have no part in music hardware, its just ridiculous.:mad:
I'm glad I'm not the only one who doesnt understand why they would want money for every iPod sold. Is this how Microsoft plans to "kill" the iPod with their Zune? By distorting the mp3 market with such kind of BS :mad:

I really hope that they keep the option for a matte screen open when the upgraded MacBook Pros finally arrive.
I have been waiting a while now to upgrade to a MacBook Pro but have held off primarily as i would like to see if the enclosure gets a few nips and tucks a la Macbook!
The switchable HD bay would be awesome, and the magnetic latch and updated keyboard also would be nice but PLEASE DO NOT make glossy screen a standard on Pro notebooks!
I have a few friends who own PC laptops with glossy screens and all of them have keyboards imprinted on their screens! I cannot say from experience if this happens with the MacBooks but i'd rather not risk it....

For a programmer dealing with Terminal, Xcode, Netbeans, Eclipse, etc (not graphic intensive softwares), would this macbook air be a better deal than the 13/15" Macbook pro?
Anyone?
It depends upon the programmer doesn't it?
One concern I would have is wear on the SSD. Due to that I couldn't recommend the current model with it's limited SSD size. Look at how much space your current installation uses and then multiply by 3. That ought to give you enough excess capacity to assure that wear leveling works to your advantage. Considering how my machine is set up that would mean about 350GB of SSD.
In any event why would you even ask if an rumored un released machine is suitable for your usage? There are many factors to consider and to evaluate them you need the machines real specs nit rumors.

Lol. So many kid Apple fanboys.
iOS is clearly outdated if compared to Honeycomb and QNX.
The iPad 2 is nice, but it needs more RAM. Multitasking is just terrible with few RAM and bad OS processes handling.
Multitasking in iOS is sometimes a joke, specially if you're web browsing and using some chat app (like IM+, BeeJive etc.).
I'm glad that RIM and Samsung come with those prices.
Next months will be crucial for me to decide the successor of my iPad 1.
I played with Honeycomb over the weekend on tablet, it's toy....

yg17, I hate to say this but Obama HAD to do this to avoid the entire "birther" issue from turning into a major distraction that ends up wasting everybody's time during the election cycle next year. Heck, it's already wasted everybody's time for the last three years anyway. :rolleyes:
I think you hit the nail on the head. Trump may have made a tactical error by starting the hardcore birther attack too early. But of course he's got more tricks in his bag. He will fire one attack after another to wear down his enemy. It kind of makes me wonder if Trump is a closet Scientologist.

You should thouroughly read a post before you quote and attempt to disprove it, or in this case, call the poster a name like fanboy...
The poster before you mentioned how these "sub-$1000" laptops are JUST starting to ship THIS WEEK, not a month ago as you claim. If Apple were to release new MBP on Monday and announce them as "shipping today," then Apple would only mere days behind, not a month.
Sincerely,
Fanboy
P.S. If you skipped to the end of this post again and are about to reply angrily, please go back and read the post as you will better understand what I am trying to say...
And you appear to have skipped the first half of his post, where he mentions that a quick google search will uncover people who have had C2D laptops for weeks now.
Unfortunately I'm heading to bed, but I do remember reading a post or two, on this forum even (I believe in this thread (http://forums.macrumors.com/showthread.php?t=228145)), where C2D laptops were sighted... in retail stores... at least two weeks ago.

Under $4k whatever state of the offerings are. I am not writing about wanting to pay for expensive servers etc. I am only referring to Mac Pro top of the lines. So I am looking foward to the 8 core starter kit this Winter. :D
Mine is not RAM intensive work. I have 6GB of ram now and it is more than enough. I also have several Terabytes of HDs already. 400GB HDs are down to $100 now so Storage is pretty cheap.
Yes, with the possibility of a Mac Pro with 8 core on the horizon, it makes sense to skip the 4 core altogether. Or, start with lower end of 4 cores (say 2GHz) and then, if necessary and possible, upgrade it to 8 cores. I wonder if waiting for 8 cores is going to be a common sentiment. In that case, it would make sense for Apple to offer an upgrade path to it.
