It seems that most people are not aware of the fact that 30 is large enough sample for almost any population, and that the main challenge is not in increasing the sample size, it's in making it truly random.
This. You want a simple random sample, a sample size greater than 30, and a population size greater than ten times your sample size.
As a statistician, it always simultaneously amuses and disappoints me when people say "xxx isn't a large enough sample size!"
Usually the sample size is completely adequate, and it's only that the sampling technique was flawed. It's extremely difficult to get an unbiased sample when doing a survey.
By the way, why is everyone saying people in the Midwest don't buy iPads? I live in the Midwest and will be getting an iPad 2 soon. Yes...probably Verizon.

Its funny that film and film cameras were so difficult to get right, but there was almost no post-processing. Now we shoot computers with lenses attached, get great technical results, yet post-process our photos to death.
I don't think this is entirely true. There was plenty of post processing back in the film days, just look at the works of Ansel Adams. It's just that the typical hobby photographer wasn't the one doing it- he sent his film off to a processing lab where it got developed and "post processed" by the lab technicians. Nowadays, with digital, the hobby photographer does almost all of the post processing himself.
The fundamentals of the process have not changed all that much, just who does them, and where/how.

I am looking for the full schedule for the developer conference. Specifically, I need to know when we will be done on Friday. This will help me book my tickets back to my town. Can someone help me with this? ( If there is another thread specifically about the developer conference, please point me to that as well. )

Where did you find it at �1.30? I paid �1.39/l diesel yesterday in Stourbridge ($8.45 US gallon)
I've started too see diesel creep over the �1.40 mark around Manchester. I seem to remember just a year or two ago complaining when it went over �1!

When did it come out? I was looking for it on Google but couldn't find aything but early reviews. Any links/directions ??
I got mine a couple of weeks ago in Japan (so mine's actually a Kiss Digital X). It was released 1 day before I bought mine. Jessops etc seem to have them in stock. I've not seen a full review yet. dpreview have a preview (http://www.dpreview.com/articles/canoneos400d/), the review should be out soonish...

Right now I have a 5870 running a 24" ACD and a Dell u2311h. I also have a TV that I want to to be hooked up, but right now I don't have an active adapter for it, but I do have an active one for the MDP to single link DVI. If I ever want to hook up the TV right now, the u2311h won't work. So I was thinking of getting another Dell u2311h and hooking that up to the 5870 with the active adapter. Then I was thinking of getting a cheap gt 120 just for the TV. I am not sure how will this would work and I would also like to get some of y'alls opinions.

... 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.

what?
that's not the same thing at all. If your mom calls you on the phone and says "i can't run this new app because it says i need to update" you can walk her through it from 2000 miles away. If she's got an ipad and the next version of Angry Birds requires a new iOS version, and she doesn't have a computer, you can't talk her through that. unless you think this would work:
"OK, Mom, what you need to do is go to Best Buy, and go to one of the macs, and then open iTunes, and sync your ipad with it, and then do software update on it, and then erase your account info from the best buy mac, and that's all you have to do!"
right.
OH MY GOD THERE ARE NO OVER THE AIR UPDATES FOR iOS? WHY WOULD ANYONE BUY SUCH A DEVICE?
I never realized this, guess I'm just too used to my G2 ;)

All Apple software and hardware can be demoed for free at any Apple store. I have brought in cameras, printers, monitors, etc... and was allowed to test them and demo them before I purchased. It's an amazing place go visit sometime.

Why on earth did T-Mobile decide to build out a network that was so strange that no one else isues it and basically phones are going to have custom radios in them to work.
If T-Moblie used more of a stardard frequency, they would be running MILLIONS of iPhones right now even though you can't buy one from T-Mobile.
Operators need to buy rights to spectrum, and there are practical limits to the number of operators that can use a particular chunk of spectrum. T-Mobile can't use the more "standard" frequencies because they don't have licenses for them, and additional licenses may not be available.
Of course, if you really want to use an iPhone on T-Mobile, you can get an unlocked one and run it on GSM.

sandy bridge processor
3g/4g card available input (just incase needed if no wifi in the area for traveling)
usb 3.0 maybe... in ivy bridge rofl..
better graphics card not going to get crippled with the intel HD3000
more ram
more battery life
