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.

In fact, DVD pricing is not the most important factor for Walmart and I suspect Target as well. Both companies employ sophisticated marketing techniques to draw customers into the store and get them to part with more money than they originally intended to spend. Brand-name promotions, item placements and even Walmart's "don't ask, don't tell" return policies are examples. The use of loss-leaders, selling products at a small loss, has proven to be one of the most powerful customer draws. DVDs are the numero-uno loss leader draw of most Walmarts, particularly those in the broad midsection of the country where it's often difficult to find a video rental store, much less a Tower, Borders or Virgin Atlantic store. I recently spent the summer in the Hill Country of Texas and became quite familiar with the Friday evening surge when customers would stream into a Walmart to pick up a DVD for the weekend and then decide to do a little additional shopping "seein' as they was there." I think the stores are rightfully fearful of the loss in foot traffic and the consequential loss of impulse purchases if movie downloads become popular. For the same reason, simply openning up an online store will not insulate them from losses since the profits accrued from DVD sales don't generally arise from the DVDs themselves, but from the additional shopping that is all but inevitable once you enter the store.

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. )
Friday is usually the miscellaneous sessions day, when the less important (or popular I might say) sessions are held. Of course you can leave whenever you want but Friday is still a full day. I would plan on staying the entire day if you can. Leaving Saturday morning is best as you can relax on Friday :)

Is it normal for it to take 45 minutes to export a 9-minute video via quicktime? I'm working off a desktop OSX and am a total novice at movie making.
It's perfectly normal. ;)
Even Final Cut Pro will only use ONE core of your CPU (I hope to goodness their new update finally addresses that blunder of all blunders of all time). Handbrake is like 3x faster than Final Cut Pro even with ONE core, let alone many. But don't blame Apple. They've been far too busy updating iOS to bother with making OSX apps faster, update graphics drivers or the OpenGL libraries or generally do anything that makes OSX better than Windows these days. Phones are far more important than Macs. :rolleyes:

You know what? There was an ex-MTV VJ that made his own show using a Powerbook and two mics and he called it "Podcasting." There was an issue of Wired Magazine with him on the cover damn near two years ago. People were using the term "podcast" before Apple did. Apple has no right to do thsi to teh people who've made their player the most successful MP3/Portable Media device EVER.

Trump, like Perot, didn't understand the fact that you couldn't run the government like it is a business. Sure, you can say that you are going to spend your own money for this or that, but for a lot of the things that is run, it takes Congress to agree on the appropriations for said government (read: pass a budget). Trump's money wouldn't do any good if it takes Congress to pass something to keep the government running, especially if they disagree on things and don't pass a budget.
Trump has a great mind when it comes to Business, so he really should leave it at that. Government, he would fail at, as bad as Perot did. On the other hand, at least the First Daughter would be hawt.

gee, the retail stores would speak out against something that would hurt their sales, wouldn't they?
apple is providing an alternative just like retail stores provided alternatives to going out to a theater when VHS was released. im certainly not saying it's better, i would never download an itunes movie, because i'd rather have a physical dvd. but now i have the choice.

Everyone has lost interest in doing this kind of thing I guess. Maybe when they removed the screensaver, for good reasons, it wasn't as interesting for some people. Upgrading to new clients can be a hassle.
I think if the stats were more interesting, I would like to have a better way to see how I'm doing against people on other teams.
Kakaostats may go by the wayside, he doesn't have individual stats anymore and the rest of his stats are questionable because of some bug.:(
We need to get more users in the team and have it competitive between us and also track the teams PPD. The stats are really fun and is what makes me want to produce more then I would otherwise do :D

Something just hit me while doing my taxes, and getting drilled with self-employment tax.
Some of the major things many are talking about cutting are Medicare and Social Security. Self-Employment tax is in place to cover payments into each by self-employed individuals (or those like me who just happen to be paid 1099 for a portion of work). So, you make major cuts to those two programs, would they not also then cut the self-employment tax, thus reducing revenue? So wouldn't it all be a moot point? Or would we still be paying the same out of our checks and taxes towards the programs, just not getting as much out of them?

Just saw this thread, so I figured I'd share some knowledge (been gaming for 8 years).
So the reason why people are avoiding these things like the plague is because they STINK. The Intel chipsets ARE more powerful than the NVIDIA 320M, BUT, that doesn't always equal better performance.
Game developers usually design games on nvidia chipsets (Hence, "Nvidia: The way it's meant to be played) slogan.
Although the 3000HD shows better specs, it's been proven to perform worse in game. The reason being that the drivers are total rubbish. Until they can improve the drivers, it's a downgrade. But then again.............who in their right mind would try and game with a laptop!? ;)

Though it's not very clear, it looks like the capacity is listed as 12(X) GB. From what I've seen in any mass storage device, 8-10% of the storage space is missing for whatever reason (my 32GB iPhone has 29.1GB.) Even if it says 120GB, that's only 6.25% gone.
This.
The settings also show a 128GB capacity.
http://images.macrumors.com/article/2011/04/04/231008-S4022974_500.jpg
If this were a genuine 128GB unit, the settings would show something like 118GB capacity.
128 GB (storage size speak = 128 billion bytes) = 119.2GB (binary speak)
Subtract about 900 megs to a gig for the OS (judging by the stated capacity on an iPod touch 4 at iOS 4.3.1), and you have somewhere around 118-118.3GB.

When my mum came home the night of her procedure, she felt really tired. You just need to sleep it off, which she did for a good 14 hours ;)
But yeah, it was like she had no control of her body and her senses were un-reactive. Just really drowsy.

I must say it has been fun watching the stats, accumulating points and moving up the chart. The only thing at the moment i have running is the GPU system tray client which seems to be doing pretty well by itself. Oh and by the way i will catch you one day DeSnousa.
Well you are 3 months away at the moment! Hopefully by then I will have a new rig, but I look forward to the day you catch me!
