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"

Why don't they just use existing standards? RTSP, H.264/MPEG4 video and bonjour. There. No licensing required.
But no.
Apple pulls the "standards compliant" flag out of their asses only when it suits them. Boo.
Apple is all for open standards...except when they are not.

Only contact pictures are synced, and a link to the persons profile is added as a webpage link in your contacts.
What facebook does with the data... I assume nothing. you assume they share it. I suppose that topic is open for debate
I've spent a lot of time adding appropriate photos for most of my contacts. The initial version that came out apparently had a bug and replaced people's photos with facebook profile pics with people who had similar names but weren't even friends in Facebook. (Even with the "replace" option turned off!)
Also, what the app is supposed to do and actually does is two different things apparently. I've read reviews around the net about people losing data. It is obvious the software is buggy.
And, who really knows what is done with the data? The temptation to mine data from users might be a little too much to turn down.

I am amazed to recently discover Mac owners pay more on average to keep the most current OS running on their box, even though OS X is cheaper (by about $70) than comparative Windows releases. This is, of course, due to the release of a new version of OS X every 18 months or so compared to the ridiculous periods between Windows versions.
Bravo to you Apple for creating and meeting consumer demand while increasing your profit! This is a great stock to own right now. It's rated as Buy at $75 and yet it still trades for around $67-$68. I still don't know why more people don't hold on to this stock.

I don't think this will serve Apple any good to stop podcasters from using Pod in the name. It will only create ill-will and lessen the use of Pod which I would think would be a good thing for Apple.

All we can do is try to live our lives as best we can. That can be done within a religion, or without.
Exactly, I agree with you, like I said, Christmas is a word to be taken by its "happy" meaning, I too celebrate Christmas as a time of peace and all that even though I'm not religious. and I agree with people being too intolerant these days about these sensitive issues.
However, I was talking about Catholicism because in my country 90% of all the population follows that particular branch of Christianity and I know first-hand how badly it is misinterpreted these days, it's an excuse for sexism, racism, homophobia, xenophobia and all the things that make me sad about the human being (in my country of course, maybe there the situation's different).
As you can see by the things that I dislike about the human race, I'm truly an anti-prejudice/discrimination person, and If you thought that I made any offensive comment to you or anybody, it was not the reason why I posted in the first time, I only thought that Mike's first comment was extremely aggressive to other people's religions, as you see, I didn't even relate to what he said but I felt the need to intervene.
Hope that clears it up.

I'd go with the Shinza one, as it is better looking and seems like it would absorb shock better. Ten bucks extra seems to be a reasonable price to pay.
I bought the foof bag (http://www.foofbag.com/), as I usually put my PowerBook inside of my backpack and I wanted something to protect it from scratches, etc. But it is a bit girly, and takes longer to get to you since it is handmade.

i mean what is $800 Australian in American dollars?
the reason i bring up the next GPU client is b/c i've heard it will be better with ATI cards than the current client. now i'm not sure if the ATI cards will pass nvidia or not though (i doubt it, but i'm just not sure).
right now intel is better than amd for folding, but that doesn't mean you can't fold with it.
with intel, if you go with let's say an i3 or i5 processor, you can always upgrade later. but keep in mind that i3, i5, and i7 860 use a different socket than the i7 920/930 and up.
Ahh stuff it I will spend roughly 900-1100 US dollars, so if you had that kind of money what would you get, don't need a screen, nor Windows 7. I appreciate your thought and help.

The one in bold is what I see the most. I've done photography for years and see new people get into the game and worry about the wrong things. Photoshop being one of them. Photoshop shouldn't even come to someones mind.
Learn the camera, learn composition, learn lighting, learn photographic techniques to get what you want such as second curtain sync, hyperfocal distancing, etc. Once you can get it done right in camera then you can take it to the next level in photoshop (skin smoothing, removing hair wisps, correcting lens distortion, etc.).
Too many people want to be a pro right out of the gate, they buy photoshop, get a NAPP membership, a fancy computer (that is 99% of the time overkill), raid storage when they've only shot 500 pictures, etc but never bother to learn the fundamentals.
I'm all for learning on Digital, I think it helps someone learn better, but focus on learning the most important and fundamental things first, then learn about the post processing. A picture can still look fantastic without running it through photoshop.
These days much of the craftsmanship that used to take place in the darkroom coaxing a master print from a negative now takes place digitally. A technically well exposed frame can still produce a crappy print at the end of a less skilled artist. Conversely, technical perfection (second curtain sync, hyperfocal distancing gobbledygook) has very little to do with art, or even creativity. Great "art" these days is even being shot on a cellphone.
Both camps (the technical-crats & the ones who are blissfully unaware of the minutiae) can produce "great" work.
Many beginners suffer from the same bad pshop skills (hey, look... I can make grass grow on his head, no make that two heads) and mistakes that beginning designers can (hey look, I can make EACH letter a different color, and a different font).
All that being said, if I was teaching beginning photographers I would remove almost everything to start (camera, lens, etc.) and go primitive and start with building pinhole cameras. Then I would progress to the end point which would be post-processing. Post-processing is huge though...
cheers,

Off the top of my head:
-Poverty
-Lack of Education
-Resentment (Much of It Deserved) towards Western Nations
-Religious Fanaticism (which generally correlates with a lack of education)
Lack of education and poverty don't cause terrorism, at least in the case of Islamic terrorists:
http://www.economist.com/node/17730424?story_id=17730424
No, jihad is one of the central tenets of islam; Allah's religion must be made supreme on the planet. Hence why Osama and others are referred to by muslims as mujahideen, holy warriors, as opposed to terrorists.
The qur'an (numerous times) tells muslims to strike terror into the hearts of unbelievers, muhammad said he was made victorious through terror.
So, islamic terrorism will still go on until the entire earth is made islamic. These are facts, alas.

I'm kinda glad I waited on this, but maybe not. The trial versions of games online is almost worth the price. I don't know a good place nearby to rent games, and I'm not doing that Gamefly or whatever thing for $8 a month because I wouldn't rent THAT many. Those demos make it easier to commit to a game.
I just bought Star Wars: TFU today used. I got the Sith edition after the guy at the store explained it to me. You save $5 overall ($40 versus $15 for original and $30 for addons) and I don't have to clutter HD space that I may need later.
The Magic game I bought from the online store is awesome. There look to be a lot of other good online games as well. I do wish I didn't have to run a network cable across my floor, but I saved $150 doing that. I can find rug and cover that thing up if needed.
So awesome recommendation. The PS3 might be nice, but I love this thing so far.

The .mac mail has been an embarrassment to Apple for some time. Ugly as sin and very limited. Strange, but Comcast updated their webmail interface this week also. The one feature I wish that Apple would add (unless I've missed it) is a button for "report as spam." I get more spam from my .mac account than from my Comcast account; with Comcast, you can report it and have the sender blocked.

Wouldn't using the "extra" electricity to power fans to decrease heat lead to less "extra" electricity???? :rolleyes: I hope they really think this through - and I'm sure they will. Of course powering fans isn't the only use for electricity.
Using the electricity to power fans would actually improve the efficiency if the thermoelectric device is placed between the processor and the fan. This would increase the thermal gradient and generate more power than if you were relying solely on heat dissipation to get your gradient.
The only problem with this solution is that high efficiency thermoelectric materials, by design, have low thermal conductivities, so it would not be a good idea to place this between the chip and the heat sink.
I am also skeptical about the claim of 30% efficiency. If we had thermoelectric materials that operated at that efficiency, we could all say goodbye to refrigerator compressors and turbine generators in favor of devices with no moving parts, higher reliability, and no CFCs.

#1 there is no front page news here... Sesiously people? It's two guys having coffee and one overheard line someone claims of heard without any real substance or context.
...but to add to the humor aspect going on here... I think Jobs wears the same thing every day to express solidarity with all the Apple users that have to settle for fewer choices and options than PC users.
You want blu-ray? Look I want a shirt I don't pull over my head every morning, but I get by..
You want a replaceable battery in your iPhone? Look I want a different pair of shoes but I get by...
You want USB ports on the iPad? Look I want to wear shorts some time, but I get by...
You do realize one of these "guys" is being indirectly sued by the other don't you ?

It is surely embarrassing for Apple that a 3rd party developer can write an app that will download and upload from the iDisk far faster than their own Finder.
If I'm going to iDisk, I use Transmit. Otherwise it's not worth it.
I'm in no hurry. Would rather not buy Transmit. iDisk is incredibly slow, but no skin off my back (I don't use it too much). Interesting to learn that it is the application, and not something inherently sluggish on the host end.
