Are you living in 2005 or so? Recent SD cards already max out at 64GB. That is already ~100 CDs worth of data.
Honestly. What's that guy talking about?

... 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%.

They Can Aways Resort To 10.4.9.1, 10.4.9.2 Etc.
Nah, if they need to go past 10.7.9, they can go for 10.7.10, 10.7.11 .. 10.7.93 or whatever.
The numbering scheme just looks like it's base 10. It ain't.

Except of course, the Unix backend that powers OS X also powers ATM machines, practically every cellphone, a lot of cars, and many other servers/embedded devices as well.
You're right that Windows has the major retail cash register & ATM market down. However, a lot of stores don't use Windows (pretty much any small business that uses those casio cash registers doesn't, and many chains like 99 cent stores just use those tiny keyboard-is-the-computer registers that I am 100% certain DO NOT run Windows).
On that note, I can tell you that Dish Network uses Linux on all of their receivers, but then Comcast and VZ use Windows on their receivers *ponders*

I'm getting a really intrusive Head and Shoulders ad banner at the top of the page. Whenever your mouse pointer hovers above the banner, the banner expands, and a video automatically starts playing. This can happen quite easily when you go to click on another browser tab in Firefox/Safari/Chrome/etc.

Spending $400 on Vista Ultimate Edition makes up the difference. :) Although the operative phrase here is "most current OS running on their box"--the most current Windows is six years old, so if people want to complain that it costs more money to keep up with modern OS updates than it does to have no major OS updates at all for over half a decade, that's not exactly something I consider a negative. I've been using Vista pre-RC1 for a few days and besides some graphics updates it feels just like XP. The gadgets are not quite as nice as os x. Beyond that, Areo is super slow when you have several applications open and to run it you need 1 GB of ram or that's what they recommend. Vista is a resource hog. Don't get me wrong, it's a nice update, but it has a long way to go.

Hi Guys
I have got a netgear readynas duo with my itunes media folder and library files on. When i open itunes it all connects fine. But when i restart the mac and open itunes it says it cant find the library folder and i have to browse to it using the "choose library" option.
I know this probably means that the nas hasn't mounted but when i go into finder before opening itunes and click on the nas under "shared" it slowly logs in and then shows me all the files.
Is there anything i am missing or anyone else got experience setting this up with a readynas?
Thanks

I'm glad I read some reviews- I was about to try the contact syncing. In retrospect, that was stupid to even consider. I have a lot of value in my address book- info collected over many years. Why would I (1) send all that data to Facebook (do they keep it? do we know?) and (2) let said 3rd party app have run of the house, updating/deleting any and all of my contacts?
Like I say, I almost did it. But it would have been stupid. I *might* have been saved my MobileMe since I'm usually notified before it updates a given percentage of all my data. But still- a risk I don't want to take.

What size is everyone getting? I will be picking up a 32gb since they are out of the 16gb.
Grrrrr, I can't decide. Looks like I'll probably get the 32GB.. 399 + $45 taxes. Anyone think $444 worth it for the older 32 or do better deals exist? I'm somewhat convinced since it is new.

Well, I own iWork, and here's my .02...
Pages seems to be a cool app. The templates look really cool, and would really spice up various documents I write for school and elsewhere, where before I simply had text and nothing else. But as a pure word processor, my first impression is that Pages blows. I admit I haven't used it more than about 30 minutes, but I wasn't impressed at all.
And no, I don't even have Microsoft Office (well I had Office v.X, but it's not installed... thinking of it, I'm not sure where the CD is...). I use TextEdit, which, since it's update with Panther, serves perfectly for my word processing needs, which is extremely modest.

Hasn't Apple always been known for producing systems usable by the Everyman? Whereas the ubermenschen were off using UNIX systems at first, followed by Linux, Apple computers have always appealed to those who wanted to pick up a computer and start working, without technology getting in the way, at least since the Macintosh...

For those wondering, you can get a beta key if you preorder the game. You get a key immediately if you preorder in person at Gamestop, and I know that Amazon does it online but it may take a few days for them to email it to you. I went and preordered yesterday and got in on it.
My brand new 13" MBP with the 320m runs things pretty well, though I think the screen is a bit small for an RTS. At times I had problems telling the units apart unless I zoomed in pretty close, but at that point you're not exactly poised for a quick response to anything. Going to try it on my desktop later with a 22" screen.

There was a study a bit ago that showed that complexity drastically reduced participation in altruistic activities, while simplicity -- especially exact instructions on how to participate -- drastically increased participation.
I think that's applies here. Using a Mac is so simple, generally speaking, that the folding@home pages seem obtuse in comparison. The pages are all ugly, and instructions are unclear, and files seem to be missing that instruction pages reference.
To increase participation I recommend that a very clear communicator make a new thread (perhaps a sticky) with *dead simple* step by step instructions w/screenshots on how to install and turn it on (circa 2010). Maybe even a screen flow that just shows exactly how to it, hosted on a service with crystal clear video like vimeo.com. Get our mirror neurons goin', yaknow?
Case in point, I'm having my own issues. Where exactly is the screen saver? On http://www.stanford.edu/group/pandegroup/folding/OSX/OSX.html, it talks about it, and say to grab it off the download page, but I just can't find it. Makes me feel dumb, which is hardly what you want in a social endeavor.
Beyond my notebooks, I also have 2 8 Core Mac Pro's I'd like to put into the game, but I really only want the processor power being used when they're idle. I need that power to myself at the other times. Screen saver or idle time processing is perfect.
Second, I did install just the basic install of http://www.stanford.edu/group/pandegroup/folding/release/Folding@home-OSX10.5-6.29.3.pkg.zip in the meantime. Activated the client in System Preferences, and hit the enable button. When does this thing activate? It's not showing any activity in Activity Monitor yet. I guess maybe this does idle time processing w/o any visual feedback?

I doubt a software update can magically change your crappy Intel 950 in to a worthwhile GPU.
I keep waiting for one of these updates to properly clock the MacBook Pro's GPU. Now that is ridiculous.

This is a common refrain from conservatives who will often reference the Laffer Curve and will argue that if only a state lowered its taxes, more money would become available.
The Laffer Curve makes sense. You find a balance and you have taxes that are low enough not to hinder the economy and high enough to fund the government. I really don't understand where this "keep lowering taxes" logic comes from. It certainly has nothing to do with the Laffer Curve.

I could see it being beneficial in some cases, such as being used as an access key to identify you or to identify you as the buyer of E-tickets (but at the same time, it would allow retailers to identify you when you walk in the door; which would allow advertising conglomerates to collect even more data on you. Wait until individual aisles have readers - "Dave walked down the toothpaste aisle at Target on Saturday, November 3, at 5:13pm. On the 4th, he walked down the condom aisle at CVS at 9:59pm." :eek: :eek: :eek:
(Seriously Folks, this RFID thing Apple is plotting might not be the best idea.
Apple will probably try to charge retailers and advertising companies, such as
Doubleclick (which will become like the credit bureaus of consumer data), but
it will make George Orwell's 1984 one step closer)
