I wonder how "Time Machine" is implemented.
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. The concept is virtually identical, except that in databases the default behavior is to delete old versions that no transaction is using any more. Such file systems are often implemented now as MVCC-style databases with file system semantics.
In fact, PostgreSQL used to have a feature many years ago called "time travel" that would let you query a consistent view of the database at any point in its past.

Wouldn't surprise me if Lion and iOS 5 are one and the same... if that's the case, and since Apple really needs to get iOS in the 21st century, I can believe this...
So much hilarity in this comment.

A bit pointless given that no software utilises the extra cores yet. But nice to know, I guess.
I'm still getting used to having two cores in my laptop!
This is a bit of a chicken and the egg problem. Hardware companies don't want to release multicore hardware b/c no software is out to support it and software people don't want to ship multiprocessor software b/c no multiproc hardware is out. Since there are a few multiproc computers out now, some software companies might start multithreading their apps, most people probably don't have it them yet.
Also, some apps won't really benefit from being multithreaded. Take a basic calculator. Why would you really need it to take advantage of multiproc computers? It isn't that processor heavy to do 2+2. AV software, like iTunes, Final Cut Pro, etc., could greatly benefit from multiproc systems. One core can do the audio while the other does the video for FC or iTunes could use one core for playing music and the other for ripping.
Something I'd like to see is to have AV stuff offloaded to the sound or graphics card to speed it up. I've heard of a company called Aspex Semiconductors (www.aspex-semi.com) that designs PCI cards that speed up MPEG encoding. Might be nice for video pros.

A lot of 3d programs will use as many cores as are available when rendering.
And I would say that the next versions of many programs will be better suited for multiple core processors.* They are way too common for software developers to ignore them any longer.
Yep. Not all of the software I use taps all the cores but the 3D renders I do shallow every inch of the CPUs. I have Maya with Mental Ray hooked to 2 computers, a quad and a dual. When I hit render the CPU usage hits 100% on all 6 processors. While having all these processors working is great I have noticed that my quad has lots of pauses in the finder doing simple things, even if nothing is running. Everyone else I know that has a quad has the same issue. I have to believe that there is a trade off for having all these processors, it seems they trip over each other on the small stuff. I hope the next version of OSX will take a look at this, in light of the fact we will be jumping to 8 or more processors.

AMEN!!!! This whole thread has the tone of a spoiled 13 year old's "I want" tirade. All the benchmarks show little difference between Merom and what you can buy today...and the 64 bit argument is really moot for most users because....(ready for it)....it's a laptop! Very few will have more than 2GB RAM on it anyway, and addressing larger RAM partitions is the #1 64 bit advantage.
Addressing larger RAM partitions is not the #1 advantage for me. I will not be putting >4GB of memory into my laptop. And I suspect it is not the #1 advantage for most of the people posting in this thread. If you don't like the subject matter of this thread, then don't read it. Simple as that.

Dan=='s mockup is something that I had considered before, I remember talking about it with Yvan 256 at some point as something like "the return of the Cube." I think it's a pretty good design, the guts of the Mini are so packed as it is, an expanded case would allow for a substantial upgrade in components, including the oft clamored for dedicated GPU.
Another way Apple could do it is just to elongate the Mini's case to make it just as svelte vertically, only slightly wider. Could you take a run at that one Dan==? ;)
Okay, I did some tinkering myself, just for kicks, and here's what I came up with. I thought that we were talking about a computer that was somewhere between a Mac Mini and a Mac Pro (Power Mac), so I thought, maybe the style should be a combination of the two. Let me know what you think.
It's not a Mac Plus... It's a Mac++!

This notion that Best Buy is the only one hoarding stock is typical of the stereotypical Apple fan. And once again, I've never bought Apple or Mac products at Best Buy because the staff are not knowledgeable in most cases, the same way I never bought a Mac at Circuit City for the short period they carried Macs.
But which stores are well stocked the best with iPads?
See if you can guess. I'll give you a hint, it begins with an A.
Sure you can say, those are Apple's rules, deal with it, but that doesn't make it right.
The truth probably is that some Best Buys are probably near Walmarts and Targets so they don't want to be out of stock for 2-3 weeks while Apple hoards stock at its stores. I'm sure none of them want to be out of stock for 2-3 weeks and suspect that Best Buy is the not the only offender of conserving stock due to Apple's inability to meet demand.
Not one of these chains wants to be known as the chain that didn't have iPads for 2-3 weeks giving consumers the impression they don't carry it anymore!
The only difference is Best Buy got CAUGHT!
I would bet that this directive came from corporate and applied to a limited number of stores that were faced with the possibility of being out of stock for an extended period of time.
People can conjecture here all they want, but no one really knows the details of Apple's supply promises vs. what it delivered with any of these chains.

Although the only thing that will ultimately matter is what Apple releases on Tuesday, if you want to get an inkling as to why FCP development has been at loggerheads since do yourself a favour and read a couple articles from Philip Hodgett's blog on FCP, QTkit, Cocoa, and it's unfortunate collision with OSX's 64 bit platform development.
http://www.philiphodgetts.com/category/technology/apple-pro-apps/
Which has been in development longer FCP overhaul or iPhone?
AV foundation was overkill for iOS from the outset so that would suggest is was always intended for FCP.
His articles have a funny assumption that the OS team has the most secrecy.
Surely the more valuable projects Like FCP have greater access to information and the greater control over when the broader company gets to see their work. Sure they would have been trumped to iPhone team who would seem to have free reign. The CoreOS team would seem like they are the most open their job is to turn the private API's developed by the product teams into to a public developer platform. A lot of their work is even open source.

This is a very dumb question but is Photoshop running under rosetta in this test?
If Photoshop is that is nuts.
Yes...Photoshop can only run under Rosetta on the Intel machines...there's no universal version of it.

"a perfect storm", "overreaction", "typical for the us to sue.."
... sorry, but in what ways do I benefit by having apple track my whereabouts to the day and meter? why isn't there an opt-in (apart from the general 'eat **** or die' TOU) or at least an opt-out for this? why is it so easy to access the data?
... apple deserves to get a beating for this.
they're known for focussing on the user in terms of design and UI of theirdevices... they should also make the step to focus on their users best interest in terms of privacy and freedom, rather than their own greed.
You obviously missed the point that they do not track anything. It's just a log file on your iphone, it stays with your iphone. I GOT even more news!! I FOUND a file on the iphone that stores text messages. YES PEOPLE text messages. I can read your text messages from this file if I have your phone!! Oh ya, I know you can launch the SMS app, but WHY WOULD APPLE NEED TO STORE TEXT MESSAGES ON MY DEVICE?!?! I'm suing!!

I never set up QMaster. It's installed, but I never touched it. Mpeg2 (highest quality double pass) saturates all cores.
EDIT: sending to compressor from the timeline doesn't change. FCP and compressor together use 350% CPU (400% max).

I refuse to protect others from negative consequences when they need to learn from them.

I believe that people with same-sex attractions are endangering themselves at least physically when they have sex with each other. So I'll post a link to some evidence for my opinion (http://www.catholiceducation.org/articles/homosexuality/ho0075.html). Notice, the document's author is a medical doctor.
Endangering themselves? And a Catholic website as backup? :rolleyes: :rolleyes:
Wow. Just wow.
At least we're back to the childhood anecdotes again - so in between reading all the ignorant, antiquated, religion-clouded bollocks you are spewing, we can find a little entertainment value.

Steve Jobs should threaten to switch to AMD/ATI solutions even if just for leverage with Intel to get discreet graphics chips in these machines.
If this is true, this is a pathetic technology compromise in my opinion.
lol... You really think Intel is the reason Apple laptops cost what they do? Really?

If the power consumption is the same... does that mean that the Merom and the current chips suck the same amount energy while going full throttle?
If the above is true, if you turned down the Merom to match the speed of the current chips, wouldn't the Merom be drawing 20% less power?
In other words if the Merom and the current chip were both going 60 mph down the freeway, would the Merom be drawing less power?
Am I missing something here (such as the basics of electricity, the basic way that chips work, etc.)?

Maybe its just efficiency... As days past and R&D continues to evolve, chips will be more efficient and they'll produce more power for less energy..

On Friday, though, the college issued a statement accusing him not only of being gay, which it called contrary to traditional Catholic doctrine, but also of misrepresenting before he was hired that he was a member of an independent branch of Catholicism.
He denied both accusations Saturday, saying he never hid his sexuality or his affiliation with the Old Catholic Apostolic Church of the Americas from school officials.
Does he feel same-sex attractions or doesn't he? The reporter says that the priest is "gay." The article tells me that the priest denied both accusations. If he denied both accusations, he denied that he was gay.
The reporter or the college goofed. Being "gay" isn't contrary to Catholic teachings. Living a "gay lifestyle" is contrary to them.

According to the school's website (http://www.chc.edu/News/2011/February/statement_regarding_jim_st_george/), he was not fired as the OP's article suggests. Rather, his contract was not renewed. AFAIK, adjunct instructors do not enjoy the same privileges as tenured professors. If his contract ran out and was simply not renewed, then that's that, unless it can be argued that the college has some legal obligation to offer a new contract.
well assuming what you say is true then every legal right to do so. Hell it could of been that he should never of been hired and HR screwed up and hired someone that did not meet all the requirements. They honor the contract up until it was time to renew it and they did not intend to renew it to fix the mistake.
I will say we can expect a lot of adjunct instructors/professors to be out of work soon because univerisities are being forced to cut cost and those are the first ones to go.
