b) Any backup of a live system suffers from not being perfectly consistent (as the backed-up system changes during the backup), the faster the backup, the smaller the inconsistencies.
Only poorly designed backup systems have this problem - the majority of systems around can make a consistent point-in-time backup of a live system.
See http://en.wikipedia.org/wiki/Volume_Snapshot_Service for a description of the most popular solution to the live backup problem.

This is the end product of capitalism and/or neoliberal policies. Look into "the race to the bottom" in terms of international relations.
All by design. All well understood, but rarely spoken about to the public.

Something that was highlighted to me the other day is that 'apple staff can not book holiday on the 20th/21st/22nd May to mark the 10th anniversary of Apple Retail Stores.'
So, likelihood of MBA and iMac updates available for that weekend maybe?
Still, I have a 13.3 MBA ultimate, and yes I do game on it regularly - in a casual manner. I would hate to lose that ability - it somewhat loses plausibility as a laptop worth �1500! If I really want to game I would use a desktop, but a real leader in it's field, should have the ability to do everything at a reasonable level!

Not good. I need an explanation.
What? You think GM's OnStar, and the other car manufacturer's systems, don't keep a record of exactly where your automobile has been? All cars have black boxes these days. You think your bank doesn't know where you've been and what you've bought? You think the government, and most companies, don't already know more about you than you do yourself, like where you go, what you buy, who your friends are, what political persuasion you are?

MacBook for 999$ with some up features would be the deal for me !!!!!
Otherwise just throw in some of that C2D chips and let it rock !!!! :D

Maybe this MacBook Pro update will incorporate a retina display which the high resolution wallpaper in Lion hints at.
Guys... seriously. Retina displays aren't happening on anything larger than your iPhone for a while. I don't care what size icons or wallpapers have been spotted. The cost for screens of that resolution at that size would be absurd.

You have a fundamental misunderstanding of how those adapters work. Going from thunderbolt to USB 3 would require active electronics embedded in the adapter. The $6 MDP to HDMI adapter is just copper internally because the signaling is compatible from the source.
So did you miss the USB to PS2 adapters I posted? :rolleyes:
Again, you have a fundamental flaw in your argument that you're not addressing. It doesn't matter if the bus is capable of delivering massive speed when the source is incapable of serving data fast enough. Any single-drive enclosure that is currently available will be incapable of maxing out a USB 3 connection. Again, any single drive enclosure doesn't need USB 3 and that's not what I'm talking about. I'm talking about the future, a couple of years down the road there will be affordable external SSD's and you will have an SSD in your machine and the only bottleneck is going to be your connector.
When they contain active electronics, they get expensive. Apple's own MDP to dual-link DVI adapter is a great example, at $99.00. USB 3 and Thunderbolt are not electrically compatible, and therefore it is impossible to have a simple copper-only dongle that has a TB port on one end, and USB on the other. Wow, you are using an Apple adapter for price comparisons. :rolleyes:
Apple sells mini-display port to HDMI adapters for $30 when you can buy them for $5. Find a better example.
Then why do you keep pointing to that article as proof that USB 3 is incapable of reaching it's theoretical maximum?Uhh, I'm not? USB 3 has overhead and I've yet to see it actually go its maximum, when have you ever seen USB 2 reach 480Mbps?
USB 2 is the universal standard for high speed devices. If you think otherwise, you must have never used a USB thumb drive. You may have never used a USB thumb drive? L.o.l.
USB 2 is TERRIBLE at high speed data transfer, 'standard' or not. A PS2 port could still be standard for all I care.
Thunderbolt in a copper implementation is capped at 10Gbs. For higher speeds, the physical connections become impractical for "normal" devices, which is why Intel designed TB as a transport bus, say for a single cable between a tower and a monitor, which would then break the TB bus back into it's component protocols, including USB 3. The copper implementation is limited only by the cable and not the port.
Which as I said above, makes it practical for a transport bus. For replacing USB? Not so much. Backwards compatibility alone will likely dictate the continual presence of USB 3 ports on virtually every computer for years to come.
I never said it would replace USB. I said they compliment each other. I said USB 3 is hardly needed as all of the heavy lifting is done through Thunderbolt then you leave the low bandwidth peripherals (that USB 2.0 was capable of handling) to USB 3.0.
Is it "difficult" to carry an adaptor? Of course not (weight and size wise).
But in real life, you run into situations where you don't have it on hand. Like the noon conference at my residency program where we had problems with the laptop on which an attending was to give a presentation. One of the other residents had a MBP and volunteered its use, but...no DP adaptor to connect to the projector. I can only imagine how many times that scenario must occur each day at businesses, etc.
It's a poor solution compared to having USB 3 built in.
In real life you should carry around your laptop in a bag or sleeve that has everything you need in it. USB 3 is not a necessity and the majority of devices will continue to be USB 2.0 compatible as well before 3.0 takes off and Thunderbolt steals all of the high bandwidth peripherals.

I'm as pro gun rights as anyone, but this sounds like a problem for the security guard. Unless that guard's life was in danger, there was no reason to shoot anyone, especially in the head. The placement of that shot was no accident.
That being said, I'm sure there are a lot of facts we don't know. Innocent until proven guilty, of course.
According to SD news , camera shows the guard took over 10 rounds directed towards him before returning fire, over 40 shots fired by by all 4 present 1guard 3suspects, so I would think deadly force was indeed needed, and FYI he was not a "Mall Cop" he was working for a privet security firm that ear all licensed to carry guns....

Kentsfield is two Conroes on a single die. They don't share cache like the previous Pentium D chips. So they'll each have 4 MB of cache and then communicate over the front side bus.
Minor terminology correction - the "die" is the silicon chip, the "package" is the carrier with the pins....
http://www.xbitlabs.com/web/2006-6-22.html
Kentsfield consists of two Conroe dies, each featuring two cores and 4MB of L2 cache.
See http://www.tomshardware.com/2005/12/04/top_secret_intel_processor_plans_uncovered/page4.html
(this shows a Pentium D image, but Kentsfield is doing the same trick.)

My first question is if the Mac Pro offers less of a performance increase than it first appeared, (for the time being at least), would Apple use this as an argument against a Conroe Tower?
I'm still behind Apple increasing their product lines, (Conroe Tower, 13" MBP, 15 & 17" MBs), and they have effectively done just this with taking teir consumer iMac offering from 2 standard models to 4. Can we expect more of the same in the future?
Roll on September 12th and beyond.
Conroe Tower FTW! ;)

I ordered a black 80GB Ipod last night, after approval from the wife.
I had a bad feeling about it, and promtly cancelled this morning.
My current Ipod is a 60GB Photo, and I have been looking to upgrade to video for some time, but I can't shake the feeling that this update was very minor, with a price reduction thrown into the equation.
I reckon, macworld in January there will be the iTV (or whatever it's called), and a new 6G widescreen iPod, with a few more movie companies thrown in.
So I think I'll ride it out until then.
I was ready to buy the next great iPod thing yesterday. My credit card went promptly back into my wallet and will remin there until we have a "real" iPod update.
Kind of disappointed this is what Apple sees fit to go into the holiday season with. Guess the rumours about the new iPod large screen being way behind were true.
I can't help but think they wanted to launch iTV with the movies as well - otherwise we would have never seen it.
*disappointed*
I will be buying a shuffle when someone builds a sports case for it, though.

This is the downside of "Open Source". I have both Android & iP4. I have to watch what I install on my Android but not with my iP4 (The plus side to "Closed Walled Garden".
It has nothing to do with open source. Most of Mac OS X and iOS is open source (http://developer.apple.com/opensource/index.html). Open source projects tend to have much better security records than closed source projects.
The issue is that the Android Market is an open market. Google does not audit the items prior to their inclusion in the Android Market. If Google curated the Android Market, it would be just as secure as the iOS app store.

Yeah, I think they want people to download content starting today knowing that they'll be able to watch it on their nice big flat screen tv in the living room soon.
Steve jobs said "nice big flat screen tv" a lot during the itv intro, didn't he?
It is a loaded term that is generic for HDTVs (plasma, LCD, what have you). Very appropriately used IMO.

I am going to be in the market to replace my 24" 2.8 rev. A aluminum iMac (Aug 2007) when these come out with a new 27". I will be consolidating to an iMac and iPad 2 since I no longer feel the need for a 13" MacBook Pro as well.
Sell the MacBook Pro and iMac to fund the new iMac or close to it. However, I will wait until later in the summer and get a 10.7 Lion pre-loaded machine. No sense in buying that close to a major OS update.

I'm still taken aback by Sun doing what Intel's doing now, but doing it 8-10 years ago. What the heck happened to SUN?
Were you reading propaganda from Sun, or something from an unbiased source?
The P6 systems that you're talking about in the mid '90s were very similar in architecture to today's Intel systems.
The P6 systems had a shared FSB, so memory bandwidth was shared by the two processors. The SPARC systems usually had a crossbar switch, so that in theory each CPU had a private memory path. (The Woodcrest systems have an FSB per socket, to a shared memory controller.)
While the crossbar really shined when you had 32, 64 or more processors with many, many GiB of RAM - for a dual CPU system it really wasn't worth the cost.
Woodcrest, the PPC G5, and AMD aren't using crossbar memory controllers today....

I thought 10 Mega Pixels were possible with some tech that is suppose to arrive at the end of this year for phones.
The weak link is the lens. Basic physics says that the resolving power of a lens is proportional to it's diameter divided by the wavelenght of light. Light is not going to change any time soon so if you want to get a clear sharp image you need a certain physical diametr lens. If for some reason you can't have a big lens then what's the point of using a 10MP sensor? Actually if the device is size constrained using fewer pixels on the same size sensor (larger pixels) will improve low light performance. Bottom line: There is an optimum number of pixels, more is not better.
On the other hand if you are selling to un-educated buyers "we got more MPs" is good for marketing purposes even if it is counter productive on technical grounds

You counter point is just as silly.
He makes a wonderful counterpoint.
People are willing to give up freedoms one inch at a time. But when you realize how much you stand to lose, or how much you've already lost, it takes on a different perspective. What is going on now, with Apple's control over what applications you can run on your general computing device, would have been deemed silly just a few years ago. But somehow its different because this computer is an iPad and not a Windows PC.
