I'm not a big fan of GM on the whole, but credit where credit is due, as the company considers selling a diesel-engined version (http://www.cleveland.com/business/index.ssf/2011/02/general_motors_considers_at_di.html) of the Chevy Cruze in the US.
In Europe, Australia and Asia, where GM already sells diesel versions of the Cruze, the diesel is the most fuel-efficient offering. Based on European versions of the car, an American diesel Cruze would probably get about 37 miles per gallon city/48 highway. That would give the Cruze similar mileage numbers to Toyota's Prius hybrid.
"That number probably would be achievable," said Mike Omotoso, an analyst in Detroit with survey and research group J.D. Power & Associates.
Omotoso said bringing a diesel Cruze to North America in a year makes some sense. The Cruze will be facing tough competition at that time from Ford's upcoming electric Focus and potential hybrid versions of the Honda Civic and Hyundai Elantra. So a diesel with great fuel economy could get a lot of attention.
"Volkswagen has been very successful with their diesel engine in the Jetta," Omotoso said. "It's about time that someone provided them with some competition."
EDIT: Another news article (http://rumors.automobilemag.com/diesel-rumor-2013-chevrolet-cruze-turbo-diesel-4-20279.html) about the Cruze diesel from Automobile Magazine.
The only real argument against doing it is the cost of federalizing the engine plus the lingering (and ridiculous) diesel-hate that automakers are convinced most Americans harbor. But considering that a) the diesel version of the Cruze already exists in other markets, and b) the car equals the Prius' fuel economy numbers, the case for selling it here is pretty strong IMO.
Perhaps a successful diesel Cruze will convince GM to put a diesel engine in the Volt, further improving that car's fuel economy? I think the US is ripe for a more wholehearted embrace of the diesel engine in passenger cars and light trucks.

All I need to know is if AJA will be supporting it.
If the answer is �yes,� then the whiny �pros� in this thread can shut up and get used to the new interface�it�s still just as pro as before.
SUPER excited about this. Can�t wait to see the rest of the suite. I�m doing a ton of hardware upgrades at my office now (new edit suites). Wish I could wait until the new FCS was out, but for now I�ll just eagerly await the day I can unleash all 12 cores of my incoming Mac Pros on some video game trailers. :D

Actually, you're wrong on both premise. On crowded roads, manuals are better. No need to constantly hit the brakes, you can better control a car's speed with a manual with compression and clutch manipulation. In traffic, I hardly ever touch the brakes.
While this is true, stop and go traffic is rough on the left leg/knee. I drove through an hour's worth of a heavy traffic jam, and I would have been perfectly ok with using the brakes instead.

I think this is the wrong way to go!
Its pulling apart mac os into a waterd down version of itself they will continue to add this stuff untill there is no difference between iOS and Mac OS!
What we'll be left with is a powerfull but waterd down mac iOS/hybrid platform with downloads through the app store like the iphone and ipad killing the powerfull features we have but running on every apple device!
I personally think apple will kill the ability to download any content through safari in the future in mac os!
So all apps will be vetted by apple and all music/films we HAVE to be made through itunes no popping on to amazon or whever to make a purchase through a browser on your imac or macbook!
I hate the direction this is going they are building a walled garden around mac os slowly and dont be supprised the ports start disapearing on the macbook soon for a 30pin dock!
Bad move apple!

For a start HD-DVD players can play in 1080p, its just the xbox360 that cant. Th HD-DVD player which comes out for it may be able to, I dont know yet.
Secondly, its not whether it has a blu-ray drive alone, if it did then there is no point buying it, just buy an extra hard drive. It has to have an HDMI connection so that it will also work as a blu-ray player in your HDtv.
I have both an xbox 360 (and I will get the HD-DVD player for a steal I might add) and a Sony Vaio AR with blu-ray hooked up to my HDtv. Yes it is expensive, but when you see the quality its definitely worth it.
I am going to steer clear of the Playstation3. The ps2 and psp just didnt impress me enough, although it will win the console wars simply because its a PlayStation. When you think about it, it has never really had the best console, N64 was better and would have won the first war had it not been on cartlidge and the xbox was better because of the online play, the ps2 was shocking online.

The existence of this data has been known for some time now.
Further, some googling suggests that Apple had already responded to some congressmen's inquiries on the subject, again, well before it got this level of publicity.
From what I've read, they apparently collect locations, WiFi MAC addresses, etc, _anonymously_ (not retaining information that would track any particular person or phone, unless you _choose_ to track a lost or stolen iPhone).
Now...why would they do that? I just thought of one reason.
Geolocation by WiFi MAC address (the only way iPod touch or non-3G iPad can geolocate, if they can't use cell towers and don't include GPS) depends on a database of locations and WiFi MAC addresses. Apple probably has previously used one licensed from Skyhook or Google. I imagine that was built with equipment carried in delivery vans, or in the same vehicles that take Google's "street view" panoramic photos. Licensing access to that database must cost Apple something.
Now...what happens? Somebody says "duh, an iPhone has WiFi and a GPS, that means we've got a fleet of surveying equipment already deployed." Doesn't matter that they can't schedule the coverage; sooner or later, someone is likely to drive near just about every fixed WiFi AP on the planet with an iPhone. Now...the data quality wouldn't be as good...but even whoever did the earlier database must've had that problem (people with mobile access points would confuse the heck out of things, for instance). So maybe it takes multiple hits to confirm something as fixed, or to improve the accuracy. But eventually you still get to the same end result - a WiFi MAC address vs location database that Apple owns free and clear.
They might even be able to do some work with cell tower location data, and perhaps produce data good enough to compete with the existing geolocation database providers. After all, Apple does have to maintain some infrastructure for various functions: their notification servers, software update servers, etc. Anything they can get as a side-effect of the normal operation of iDevices and their infrastructure, that helps pay for it, lets them make a bigger profit and/or be more competitive (remember, for all Apple's rep for high prices, the iPad 2 supposedly is as well or better priced compared to competing devices with similar specs).
The question here probably isn't whether the data is being abused; and raising that question is IMO _pandering_, not surprising for a liberal, who after all must have idiots for constituents, or they wouldn't have been elected. (I mean, really, Heinlein summarized economics concisely with TANSTAAFL, and there _is_ something usually ignored called the Tenth Amendment, which basically says the states can be socialist if they want, but the federal government can't.)
The _real_ question is what safeguards are in effect to minimize the potential for abuse. Ok, we theoretically need a warrant for this sort of thing (although I wouldn't put it past individual states to play fast and loose). But what about foreign governments, already inclined towards police state behavior? What about people _knowing_ what risk they're putting themselves at in case of some civil suit?
IMO, Apple needs to provide and prominently _document_ a way to clear the saved data, and/or document the degree to which disabling location services prevents its retention (let alone anonymous reporting) in the first place. (For jailbreakers, I gather there's already a Cydia app that once installed, will automatically delete data older than a few minutes.) People need to understand that encrypted backups would make the information sync'd back to their Mac or PC safer. And so on.
Generating hysteria is perhaps a useful political tool, for those inclined to address themselves to the least common denominator. But asking the more specific questions which would lead to real answers takes more than PR, it takes a functional brain, or at least the sense to hire a staffer who has one or can consult one.

it took me roughly 18-19 days to go from 3 mil to 4 mil. my best yet. but 4 to 5 probably won't be any faster, but we'll see

As far as I know, Snow Leopard "fixed" what Leopard started. Mac OS X Lion is a completely new OS with new features, most of which are not present in Snow Leopard.
haha, no chance. Tons of new features here. I can see Apple charging less than $129 if they go the App Store route, but if boxed retail is released I'm sure it'll be $129.
Snow Leopard was a bigger upgrade than most people assumed--but only in an under-the-hood sense. The switch to a real 64bit system (with pure x64 kernel and extensions) was a big deal, albeit an invisible one. All the system core revisions, a 64bit finder and a $29 price made Snow Leopard a worthwhile update.
As for all these "tons" of new features that would make Lion worth $129: I just don't see it. Smaller window controls, iOS buttons and scrollbars and a few other iOS-derived tweaks and features just don't seem like that massive of an upgrade. Auto-saving, application 'resuming' and iOS-like state-suspention don't make a whole lot of sense for a desktop OS (perhaps if a machine is all SSD-based, with no physical discs, these features will allow Apple to eliminate swap/VM). So all-in-all, Lion feels a whole lot like Snow Leopard: a collection of refinements and nice, subtle improvements.

We'll just see what happens. I bought the 160 not too long ago so i won't be upgrading but it's good to know it's still around. 4571 songs of uncompressed audio and counting. gotta love the classics.
Uncompressed. That IS the key. Friends don't let friends buy compressed faux music. And play your uncompressed music with your tube amps and AR 3a speakers. Howz that for classic?

I do think some people genuinely believe it's a choice. It's hard for some people to imagine that not everyone's minds work the same as theirs, and not just related to homosexuality. Chances are, someone who considers homosexuality a choice likely has issues with other groups of people as well.
I think that people who blelieve homosexuality is a choice have some degree of homosexual attraction andchoose not to act on it.

I can not believe how long it has taken me to finally bother to register here...And it has taken the release of an iMac to do it.
Ironically I've been a longtime reader myself and just registered because of this article, though for exactly the opposite reason as you. :D
And yes I realize my complaints about a mid-range tower probably seem pointless to most. But the iMac just doesn't seem to meet my needs. I'm happy with my current dual monitors (which match in size and resolution) and I'd prefer more than a 128mb graphics card.
Moreover, I've been a Mac user since 1993 and never owned a single LCD-based Mac which didn't have a dead pixel. That's about seven Macs, including my current MacBook. Bad luck, I realize but I'm just not buying an all-in-one desktop from Apple. :p

I'm gathering either Macbook Light or Macbook Air from these rumors because immediately "Light as Air" comes to mind. I have not used a CD or Floppy for my data needs in a couple of years because I now rely on USB Flash drives and with SDHC cards now getting into the under 100 USD range (gathered from newegg.com prices) for 16 GB of storage just makes so much more sense to me.

I got a another newbie question
I am planning on moving out of Windows (7) and onto MAC OS X, but I want to wait for Lion since its close to a finished product. Now my question is, if Lion comes out, would that mean every Mac (Mac Pro, iMac, iMac mini, Macbook, MB Pros, etc) would have Lion installed/packaged or is there a specific mac that will have Lion on its first day and the other macs would have to wait???
All the (new) Macs will have it right away, Macs purchased shortly before the release get a cheap upgrade option (if I remember right) and most of the older macs should be upgradable (I would suspect every intel one, but I wasn't following the minimum spec)

For all those saying about SSD - don't forget that after approx. 2 years of regular use, the drive is pretty much useless. read/write speeds drop off considerably as they age. As unbelievable as it may seem, SSD still has a long way to go before it can replace the hard disk drive.
:rolleyes: SSD is far more reliable than a spinning platter on a highly portable handheld device. Read/write speed? This is for an MP3 player, not a gaming PC. And it's not like the performance of the hard-drive on the current classic is great either. There's always a lag here and there for the drive to spin up. Try browsing cover flow on the classic, it's painful.

I'm glad CR is taking its stand.
For me, the antenna issue was WORSE than people had reported. It didn't matter where I touched the antenna, the reception was affected.
True, the bumper completely fixed it, but there is still a problem with the device.
I always think it's odd when someone would join the board the same of day of their post simply to write something very negative like this which flies in the face of most user experiences. :rolleyes:

That really depends on the program, on how "parallelizable" the application is.
The simplest way to think of it is like this: Let's say you have a program that first has to calculate A. Then, when it's done that, it uses the result of A to calculate B. Then, when it's done that, uses the result of B to calculate C, then C to D, and so on. That's a *serial* problem there. The calculation of B can't begin until A is done, so it doesn't matter how many processors you have running, all computation is held up on one spot.
On the other hand, let's say you have an application that needs to calculate A, B, C and D, but those four values are not dependent on each other at all. In that case, you can use four processors at the same time, to calculate all four values at the same time.
Think of it like baking a cake. You can't start putting on the icing until the cake is done baking. And you can't start baking the cake until the ingredients are all mixed together. But you can have people simultaneously getting out and measuring the ingredients.
So that problem is partially parallelizable, but the majority of its workload is a serial process.
Some software applications, just by their very nature, will never be able to do anything useful with multiple processors.
CONTENT CREATION PRO'S will see the benefit! Like DAW's host running multiple plugins and virtual instruments etc. Video guy's that are rendering in the background while doing a file format conversion task while @ the same time doing a cut copy paste edit on some video... Any processes that are CONCURRENT! THESE are the things that will take advantage of multiple cores... the kids on myspace farting around on the net emailing and such are really useless for multiple cores and us pro guy's NEED this multitasking power... BRING IT ON!

Applications should be, and most likely are written to take advantage of available resources. A developer should be writing applications to take advantage of 8-cores already, they don't need an 8-core machine to do so.
I agree. I wonder how idle the graphics card is when not using games. It would really help if more programmers were able to write programs that take advantage of the graphics card and audio card. Too bad SoundBlaster cards are Windows only. I wonder how much faster ripping CDs and converting to different audio formats in iTunes would be if the instructions got offloaded to a Soundblaster or other sound card.
I also heard of a company called Aspex Semiconductors (www.aspex-semi.com) that designs PCI cards that speed up video processing and has something like OpenGL, but called OpenRL for video processing.. Would be cool if Aspex & Apple teamed up to make a card for Mac Pros to speed up Final Cut Pro & iMovie. Just my 2 cents.

I am not interested in Windows APIs. That's how the hardware capabilities are referred to. OpenGL has tended to lag in new features, so if the hardware has extra capabilities, it will probably support some future OpenGL version too.
OpenGL is much more like Direct3D. A part of DirectX. DirectX is just a collection of multiple API's. DirectSound is like OpenAL for example. The equivalent to OpenCL is DirectCompute.
You seem to think that DirectX 10.1 cards can't support OpenCL. Well newsflash, they can. DirectX is irrelevant in this conversation not only because it has nothing to do with Mac OS X but because it also has nothing to do with what you're associating it with.

I wonder if this may imply the coming of that unicorn rider we all know and love, the 'headless mac" (aka xMac).
Removable drives, no screen, more powerful than an iMac, 1499.99.
That is exactly what I'm thinking! Seriously there is no need for that many GPUs in the Pro and IMac requires a custom card. So where would all of these cards go - XMac is my guess.
Or it could simply be a sign of a unified driver from AMD. That would make sense as it is a smarter approach than the highly targeted drivers of the past.

Such a great ad.
They should have done something like this and not the "well you don't have an iPhone" ad.
