If you want to power the temperature change yourself, you need a high current. But if you want to generate electricity from them, then just connect them into a circuit with out any powersupply i.e. stick a fan's power terminals on that, stick one side of the TEC on a hot chip or cup of tea etc. to setup the delta T. (temp difference) then the fan will start spinning!

So if I follow this correctly. Since the fan does not draw much, you don't need that large of a temperature differential.

Also if you don't have the apps on your iTunes, I believe that if you are logged into your iTunes account and click the purchase button for an app that you've purchased before, it will pop up a box that says you've already paid for that app and allow you to download it again. (I believe this is true, I'm just not 100% positive on this)

Other than portables, i've never really seen the point in slim consoles. All my consoles are fatties and i've never thought of selling them to buy a slim.
The 360 slim looks like a little kids toy next to the fat 360. Its just soooo cheesy and tacky. The original 360 case was much better, imo.

At 2am ET my AT&T iPhone 3GS fell back to 1am instead of jumping forward to 3am. Now, it is saying 10:14am when it should be saying 11:14am. So, still broke. It is set to "set automatically" in preferences for date and time.
Same here except iPhone 4 w/ the 4.3 update. This is absolutely unacceptable.

Trackpad is larger and provides more space for fingers than the touchscreen would when you're utilizing those gestures. Difference between a swipe and a full-hand pinch.
Maybe you have really abnormally large fingers! :D
A full-hand pinch isn't that hard to do on an iPhone/iPod Touch

Working at Microsoft is not a detriment to his career. It's a boon. I think you'd be hard pressed to find people who would refuse to work at the most successful software company in the world, except the most zealot-minded Apple fanboys, such as we have here. I understand why people downvote the story, but for goodness' sake, I'm fairly sure Apple's HR people know better than us. Give him a freaking break. He's going go to do a job 8000 times better than any random schmuck off the streets (or on these forums for that matter), and that's why he got it.

I know this is more of a "wish" thread than a "likely to happen" thread, but I'm going to chime in and predict that the Air refresh will be fairly minor.
I predict we'll see Sandy Bridge and Thunderbolt (like the Pro/iMac lines) and better GPU, but beyond that, I predict same body design, no addition of backlit keys, and the worst prediction: likely the same SSD configurations. I say this based on the refreshed iMac SSD options; the prices for SSD have not gone down even in the slightest. I predict the base SSD options and even the BTO options will remain the same as they are today. Of course, I hope I am way wrong.
The last thing, which in my opinion can swing one way or another, is the RAM. I predict it'll stay standard (again, based on the iMac refresh) at 2 GB, and will not come standard 4 GB. Again, I hope so too that this will swing in a more favorable way.
Pure speculation.

Any changes under the hood allowing Win7 Boxes to join an OD domain? :confused:
More server an the start of the profile manager web app.
the profile manager also allows you to remote lock/wipe your devices but you need to have network directory set up which it was, so will investigate later more about this feature.

So, it's most likely they are going do these things.
1. One device that will work on both VZ and AT&T network
2. 32GB and 64G storage.
3. 1080P recording with 8 megapixel camera
4. A5 chip
5. Maybe higher ram or maybe not.
6. Throw in something new... like better gyroscope or something to just make iPhone 4 outdated, but nothing major.
This is BS. It's not good enough, apple.

All of these comments miss the point of what the announcement is about, institutional purchases. This is about school's buying large quantities, and really, since I have a hard time imagining that a University would be buying 10 packs of iPods .
Apple does sell iPods in institutional packs.
We've asked several Apple representatives "if I buy a class set of 32 ipods, and I want to use a paid app, how many copies does the school need to buy,
You need to talk to the developer, not to Apple. The App Store doesn't do volume licensing, because it's a consumer resource. The developer will either give you codes for each device or arrange to provide you with a master for site licensing, in which case you'll have to go the enterprise deployment route that Apple offers for large organizations.

This trend on these forums of people making posts without apparently reading the original post or any other posts in the thread before making a post is getting a little annoying.
Which of those things allows you to stream video and audio from an IOS device?
If iOS supported DLNA you would be able to do this without any new standard, there is no need for a new apple developed standard for this, I can stream video from my android phone to my TV, Bluray and PVR already. This is something devices have been able to do before Airplay came along.
It's not hat these devices need a new standard, just for apple to support an already industry wide used one.

... sooo, a thermocouple (http://en.wikipedia.org/wiki/Thermocouple) on a chip? Thermocouples have horrendous efficiency. I don't see how a such a chip in an enclosed environment (like a laptop motherboard) can achieve enough of a thermal gradient to produce enough current to be useful.
I dunno, i'm skeptical.
Skeptical you should be, but these aren't really thermocouples. The same physical principle applies, but thermocouples are really only for temperature measurement. These are thermoelectric coolers. See here (http://en.wikipedia.org/wiki/Peltier-Seebeck_effect).
If you want to power the temperature change yourself, you need a high current. But if you want to generate electricity from them, then just connect them into a circuit with out any powersupply i.e. stick a fan's power terminals on that, stick one side of the TEC on a hot chip or cup of tea etc. to setup the delta T. (temp difference) then the fan will start spinning!
Dan :-)
While what you're saying is true in principle, I seriously doubt the practicality of what you're suggesting. TECs are moderately efficient at converting electricity into a temperature differential (or being used as a heat pump), but their efficiency in the other mode of operation (Seebeck effect) is very, very low (typ. < 5%). If you take a chip-sized (~ 1 cm^2) TEC, connect it between a hot processor core at 100 C and ambient temperature at 25 C, you will not have enough power to turn a computer fan at any modest speed. Furthermore, even if you could harvest that electricity and store it, the added energy would be less than 0.1% of a typical laptop battery. :rolleyes:
If you wanted to use a larger TEC module (say 16 cm^2) on top of the 80 C CPU case, then the added energy would be less than 1%.
Estimates based on info here (http://www.ferrotec.com/technology/thermoelectric/thermalRef13.php).

Purchased: Aug '07
Model No: A1186
EMC No: 2138
Mac Pro/3.0_8CX/4x1/2x7300GT/500/2xSD/AP/BT
Logic board:
Part number: 630-7951
Serial Number: J5*****X7QB
Upgrades:
Added: 8gb Kingston memory (total 12gb)
Added: 3x1tb drives (total 3.5tb)
Couple weeks back, system blinked off. The machines powers on, but there's no chime and the system doesn't boot at all. Done the SMC reset, reseated RAM, drives, video cards etc. Suspected the logic board.
Troubleshooting (from Frys, Apple authorized) confirms it's the logic board.
Now, going through the process of pulling the old board to trade in for a replacement "X7Q" board. Probably this one:
http://www.galaxyhp.com/Mac-Pro-Early-2007-8-core-Logic-Board-ver2-new-wexchange_p_177.html
I got the machine disassembled but I am unable to remove the heat sinks/CPUs. The 4 captive screws loosen, even took them all the way out of the machine, but the sinks seem to be stuck. It doesn't just lift out as most of the online info I've found indicates that it should.
Unsure of how hard to pull on this thing. It wobbles very slightly, but feels firmly stuck on...enough that the board will flex if I pull it any harder.
More reading makes me think it might be the thermal paste is just really sticking? This is really stuck though...almost as though there's another screw I can't see. I thought if I pulled hard enough the CPU might come out along with the sink.
Also I ran across an article (after the fact) that states the order of screw removal from the heat sinks needs to be in a specific crossing pattern. Can't imagine how that matters.
Of course, I paid through the nose for this machine back in late '07. Bought Apple Care even. All long since expired...now that I need it. Getting desperate. This machine is a workhorse and I see no value in replacing it if I can fix it for 700 to 800 bucks.
Any one have ideas?

I've installed it and am now part of the MR Team! YAY! The only thing is that it's not taking any processor power, or at least it doesn't appear to. I've got iStat installed and I can't see it take any of the CPU power, and I've followed the guide (it wasn't exactly difficult) and it still doesn't show it taking any power.... I don't know if that's how it supposed to be, but I'm pretty sure it's not, and I really want to contribute to the team, so if someone could help me out it would be terrific! And my User Name for Folding is KingMookMook, and I couldn't see that listed on the MR Folding Site, so it probably isn't working... I've only been doing it for a couple of hours though, so I might not have done enough to show up on the boards.

I would say it still wouldn't work, as the OS X RAID implementation is software RAID. Hence, OS X has to boot to get the RAID array working.
In the case of RAID 1 if it did work it might break the mirror (no big deal).
Give it a shot. Worse case it won't work; shouldn't affect your data at all.
Cheers for your comments Abulia, I thought I'd give it a go anyway but you're right it didn't work. I just get the flashing power light, a loud beep then the Mac startup chime and a normal boot up. Strange. Oh well will wait for a fix from Apple I guess.
