... 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).

All mah customers is scared of you ... you bein' black and all ... so they'all stand in the other line and make my other checker do all the work.
So's I gots to fire you and hire me more white checkers.
Yeah. Let's bring back those days ... when America was great. :rolleyes:

can you please explain to me (or provide a link where it's explained) the benefits of using a 30 pin connector in comparison to a usb port? is it maybe so that apple can sell more adaptors? (i'm not sarcastic on this one, i'd really like to know)
There is an advantage to the user and to Apple.
The advantage to Apple is that they OWN the connector and will or won't grant other companies the right to include that connector into their products. So you'll never see a Microsoft or Android phone sporting Apple's connector.
The user can drop their iDevice into a bedside radio/clock or into a slot in their car dash and have their iDevice automatically integrated into that appliance or vehicle.
This means when you set an alarm on your iDevice, your bedside radio knows it and wakes you with music or alert through the larger radio speakers. Your iPhone GPS can become part of your car's navigation system, while your iPhone can become also become a hand's free phone using your car's sound system. Plus, you still have all your alarms, Address Book, and calendar available to you via voice command.
Life is good for you, and in Appleland prosperity reigns. :)

Are your APN entries correct, or your carrier file installed?
Settings > General > About - what is the value for "Carrier"?
Might be worth a reset of your network settings.
Settings > General > Reset > Reset Network Settings
This will also wipe all stored WiFi entries and their passwords and reboot the phone.

Meh. Integrated stuff always fails first. See VHS/TV and DVD/TV combo units, or the lack of updates (and eventual phase-out) for TVs with built-in cable or sat tuners. I'll take it separately, thanks.
so you have a stand-alone tuner, then, i take it? same thing.

I sincerely hope not. I'd rather have anything other than a poor metal track being played continually on the radio over the festive period.
I think that's unfair, it really is a good song. I would never consider myself to enjoy 'metal' or it's ilk (except DFA1979) but that first Rage album is a work of genius. It was a proper protest record, and we don't get many of those any more.
I bought the Rage single, I already own it and I don't care if it goes to number 1 or not. What it does show is that if people club together they can totally make a change. Admittedly Christmas number 1 might not be a particularly important change, but we have to start somewhere.
Also some money has been raised for Shelter. Surely that makes it worthwhile?

Photos of lion server launchpad, podcast composer and one of server admin.
Podcast composer seems to be a vast improvement and offers many more options.
Server Admin seem really limited in my opinion but then again it docent work for me, for showing services so maybe theres more to come.

And so it begins - this is the first of only many apps that are going to be written to work with Intel chip sets only, I'm afraid. I am, however, somewhat taken aback that they appeared this early from a major software company.
Perhaps there have been others, but I've not seen anything myself released which didn't have a PPC version available or was UB until now.

I don't get what's the problem with Garmin's view. Garmin decided to go live and have upto date maps and traffic alert. I can imagine they also have some sort of cash so you only have to d/l the map once and then it lives in your iphone. It also has an amazingly small footprint - weighs in at only 8mb and this is another cool feature of the program!
Well, that's the real question, isn't it. If it turns out this is the case, and it can cache the maps for an entire region, and if it's smart enough to grab the maps for the entire region that you're currently in and/or going to, for some appreciable radius, AND if it can keep the maps in the cache for as long as you need it (which might be "forever" for maps of your home city), then I'm willing to give it a try.
But others in this thread have already talked about driving through backcountry areas with no 3G access, and not having any access to maps. They've talked about travelling down a highway and "running out of map" and having to pull over so that the 3G can connect and refresh the maps. If that's the sort of user experience I should expect, then I'd rather stick to a standalone GPS receiver. Or buy one of the other GPS apps that have built-in offline mapping.
Garmin touts the ability to get the latest map updates and real-time traffic. Definitely useful for navigating within big cities with major highways, constantly-expanding suburbs and major road expansions in the works. But without map prefetching and caching, they are making their GPS app ONLY useful for these areas.

Finalcut, the GameStop copy may say "PC" but Blizzard's games are playable on both Mac and PC using the same disc. Even on GameStop if you open up the System Requirements, under OS it says "Windows / Mac."
That being said, the code that GameStop is usable for both PCs and Macs. The code activates the game in your Battle.net account, from there you can either download the PC installer or the Mac installer. I'm downloading the Mac installer right now (I got the code about 1.5 hours ago but I was in the middle of a final) and it says it will take about 70 minutes to complete (big file...).
Excited to play, even if it is a little glitchy at first I've been waiting for this game for a LONG time, wish I would've known I could've entered the beta before now. I have the newest Core i7 15" MBP so it'll be interesting to see how it handles that hardware, it should be plenty capable.ahh thanks for the clarifications
I'm gonna pre-order then

Technically 60% of the voting public did not want a conservative government. Only 40% voted conservative, another reason why we need a two party system or proportional representation.
80% didn't want a liberal government, 70% didn't want a NDP government. Conservatives won the majority of seats, now let them run the show for a while.

I wonder if that might be "banker's hours"? Send a courier to the lab, lab tech does the test and goes home for the night, reading the results in the morning. Who knows what kind of advanced equipment and tech the military has access to. Fly right to the Kabul lab, start the test, fly to the carrier, proceed under the impression that this is him, with the hosing-down, funeral and dumping. A few hours later, confirmation.
Though I could be wrong. :)
Genetic tests for identification usually take up to 5-10 days, but usually more than 2. Technology. heh.

If Verizon was not CDMA I think we would of seen a Verizon iPhone. I just don't think Apple really wants to mess with two different models of the phone.
disagree with you in England iphone is sell by 5 companies
I really hope T-Mobile isn't chosen...I had them for a year and a half and what horrible customer service. Not to mention that their coverage in Palm Springs, CA is horrible. Apple should go with Verizon, I did go with AT&T myself, but Verizon is rated highest of all the carriers for customer satisfaction and coverage.
I wish that more companies will sell the iphone in the US so at&t will not act as a monopoly DO YOU RIMMBER some 20 years ago at&t was broken out by the goverment because of monopoly lows? I thing its time to do it again
