This is nothing new...
I used those devices in last year for my GCSE courwork (15-16 yrs old). I used them in a drinks cooler / heat thingy.
I won't ramble on about my product, but: The devices are called "Thermo electric coolers. i.e. TEC's
And they offer 3 functions.
1. The cool something.
2. They heat something.
3. They produce electricity.
This heat / cooling effect is called the Peltier effect (some French guy) and some people call these things peltiers etc.
They work, buy passing a relativly large current 3-20 amps, depending on wattage. to draw heat from one side to another basically. one side is -10 degrees c. The other is +80 degrees c. However, if you don't power them and instead create a temperature difference, i.e. stick ontop of a hot computer chip. You wil have set up a temperature gradient. So it will generate electricity. Typically you get around 4ma per 1 degree C. So nothing huge, unless they have refined them. So in this case, the bigger the delta T, the more power. I guess it could power a fan then! Seem's easily possilbe, but I wouldn't expect battery life to be much more than 30 mins at most extra. As 1 fan doesn't draw THAT much power!
Still a good idea though!
If anyone else has any questions, on how they work, images, tech drawing, or my product, i'm happy to answer them all!
BTW: Forgot to add, the generating electricity idea, from one of these, is called the "Seebeck Effect"

Congrats Apple!!
Congrats Steve!!!
The more market share, the more vendors will be supporting our platform of choice. :D That's great news!
Let's hope that the OS is as secure as Apple likes to spout off in their ads...

If you ask me, it's pretty clear Apple will update all of its laptops before the holiday season. I personally can't wait to buy a new MB, because my 600 MHz G3 iMac is getting a bit sluggish. My question is this: Will it be a simple CPU upgrade, or will Apple change pricing and/or other hardware (such as HD capacity, RAM, etc.)? Oh, and how long do I have to wait?
we know as much about apple's next release, as about apple's 5 yrs later release

So what's this, an OLD white iPhone 4 prototype with 64 GB with a different version of iOS 4, none of which will ever be released? Wow, great news. :rolleyes:

Well, if what you say to him works, you might actually be "effed", but sadly you won't remember it. Then you'll really wonder about the looks he gives you. :D

how many of us actually care much about aperture...?
Tally me in the 'I care' crowd as well.
If the student price were $99, I could buy it in a heartbeat... but it's so close that I'm trying to find a way to get it.

Is there a way to specify which comments you get push notifications for? I'm interested in get pn for comments my updates but not really interested in getting pn for my friends status update which I comment on. E-mails are fine for those.
Anyone know? Thanks.

Ditto! Slingbox rocks! And it's even more fun when you have a friend or two in other states that allow you to use their Slingbox to watch events that are blacked out in your own area. :)

Yup. If I ever switch providers I'm putting a Slingbox in my dad's house so I can watch the NFL Sunday Ticket.
You can pay the Yesnetwork.com 100 bucks to watch the Yankees online at work, or I can watch for free on my Slingbox.

Canon Rebel T2i + EF 70-200mm f/2.8L IS II USM + EF 2x Extender II
Classic B&W mountain photography is probably my favorite of all time. I can just stare at Bradford Washburn's photos for days. I think you did really well here and I enjoyed this one for sure. My only complaint is that the right side left me wanting more, like we weren't quite finished with the ridge.

Would you want Donald Trump as our president? I am really on the fence for this one. This is the first time I am allowed to vote so I am paying attention to politics more than ever. I mean it would be good to have a completely loaded president so he "can" spend some of his money for the economy, which Trump says he will do. We all know that all politicians are liars though. Trump has changed his mind about a lot of things such as abortion, socialism, and Obama's health care plan. A little while back Trump voted for the three previous things I said but has recently changed his mind. This makes me think he will be unstable when it comes to decisions as a president. Also I don't take him seriously. So what do you think about Trump for president?
It should not matter what "I think" about Trump as it relates to your vote. But, I think you are trying to get a deeper sense of the candidate by asking others, which seems both reasonable yet misguided to me. My suggestion is that, at the end of the day, vote your conscience based on what HE SAYS and DOES and not what others interpret. You have a moral compass, use it.

Like a touchpad wouldn't it be possible for it to recognize what is a tap and what is just touching to the surface? i.e. it would only initiate a command based on a quick touch and release.

the 'what's new' page says "Work with RAW images from more than 50 camera models, including the Fuji S2, Fuji S3 Pro, and Sony A100." but i don't know which ones exactly .. i know the Fujis are new because i have the S9000/9500 which is still not supported and it didn't support any Fujis before
Did you read the previous posts? The complete list of supported cameras (http://www.apple.com/aperture/raw/cameras.html) was posted on the previous page...

I would LOVE this. I have been with T-Mobile for over five years, and they are a great company. Unfortunately I cannot get out of my new contract until Nov. so having the iPhone on T-Mobile would be awesome, hoping that they can prepare with all the data that will come with it.

Kinect is more for the kids. They really enjoy Wii Sports so if there's an alternative (or blatant clone) with decent graphics for Move or Kinect, they'll be happy. It'll be interesting what 'Family' type games are released for both the new motion sensing systems. If you're going to wildly flail around the livingroom, you may as well do it in HD.
I personally just want a shiny black 360 to put under the livingroom telly. King of Fighters '98 Ultimate Match (and maybe '02 UM?), Mark of the Wolves and both Virtual-ON Oratario Tangram and Force. Just need Hori to do another run of Twin Sticks...
:apple:
My guess is Kinects is a way to keep from having to buy both a Wii and an 360. Of the system I like I like the 360 as it has more of the games that I like on it. Now if I had a family I could see getting the Kinects for it so the little kids would have something to play but then again I more than likely would put the 360 in another room since I would not want them seeing the Rated M games that I will play.

I used to have a Garmin Nuvi but I won't be going anywhere near this!
I'd say your 500MB data allowance on O2 would be churned up in no time.
What's the problem with downloading the maps? TomTom takes up about 2-3GB on my 32GB iPhone... big deal!

Maybe you have really abnormally large fingers! :D
A full-hand pinch isn't that hard to do on an iPhone/iPod Touch
Try it. The positioning isn't comfortable for anyone.
I'd argue that you'd see Apple lose a large number of users if they went that route.

The real question is why do people still buy Macs (in increasing numbers) in spite of this... hmmm... makes you wonder...
Because more and more people are seeing that the hardware and software that apple produce is very good. Many people are willing to pay a premium for some items. there's also the coolness factor, apple used this quite adeptly with the iPods, iPhones and now Macs.
Also as AppleScruff1 stated some people here cannot admit that for many people windows is a great solution for their needs.
Not everyone needs a core i7 desktop to email their friends and family or check their facebook status. Simply put many people find windows to work out of the box without much fuss.
