I sure as hell would not want wind turbines on the roof of houses. The noise from them would drive me insane.
The small ones, like satellites dishes. You can buy them at Jaycar.

Pretty much like a weather vein or TV aerial. Provides a couple of hundred watts at 24V or 12V. I was thinking about one for if there is ever a blackout (ie a drunk hitting a power pole, it's happened) instead of needing a petrol generator.
Every home generating 500W of their own wind power with one of these little things on their roof in a city of Los Angeles with a million homes = 500,000,000 watts. As well as a solar panel at 500W too is up to a billion watts not required from any central power source.

No amount of arguing is going to change this fundamental issue.
One of the things I liked about the Nintendo 3DS was the thumbstick.
A lack of a physical keyboard, and a better controller for games, can be an issue with the iPhone. It certainly was a design problem with BOT (http://photics.com/bot-game-design-and-progress-reports). I'm designing a game specifically with touch controls in mind. The original design had a flaw. A lot of the action would be covered by the player's hand.
Yet, I don't think it's impossible to create great gaming experiences with just a touch screen. Angry Birds, Fruit Ninja and Cut the Rope are excellent examples of touch-based gaming. I don't think that could be easily duplicated with a controller.
What should Apple do about it?
...a slide-out controller?
...an Apple accessory?
Doesn't Steve Jobs hate buttons? I thought I read that somewhere.

Anyway, I've never been one to agree with the Windows people that argue the security-by-obscurity for why Mac OS X is not hacked to bits like Windows, but it would seem that this adds aome serious fire to their arguement. Here in music where Apple is the most popular and widely used, they are getting hacked (semi-successfully) more often than their WMA counterpart.
Yes and no. True iTunes is getting hacked more than WMA because of its popularity, but this has no bearing on the relative security of the software or operating systems.
The problem is that DRM like this is flawed by definition. In order for me to be able to listen to the track, my computer has to have the capability to decode and play it. Therefore there has to be a hole that can be exploited to get that information. Jon is very good at finding that hole that has to exist.
The system is guaranteed to be breakable as long as you look hard enough.
The same is not true for operating systems. The system does not have to be breakable, so now you can make an assessment based on the architecture.

I'm _sure_ that Apple has a surpise for us wrt the Conroe /Conroe XE CPU.... a nice smallish desktop Mac (we can hope, can't we?) :cool:
And if they back it up fully with software features in Leopard and iLife07, Macs should leap ahead as multimedia machines...dedicated processor for video to avoid any missed frames recordings or playing.

Apple will buy Nintendo eventually.
It's over for Nintendo.
Get ready for the iwii
I doubt it - ninty are make some serious money on every console/handheld unit sold, they are set for the foreseeable future. IMO, while the iOS is great for short bursts of gaming, it will never replace a dedicated gaming machine
Doesn't matter. Apple took in two head gaming executives. Whether they called them up or were called up, they now have major gaming players in their family. It's a pretty clear sign that they will be getting into gaming in some way.
when they get Miyamoto or Iwata, then I'll be interested
These people are fleeing the "yellow light of death” on PS3 or "red ring of death' on 360. The consoles are so poorly made that broken PS3's seldomly fetch $50 on eBay.
Apple has a real opportunity to make a name in gaming as gamers know quality and appreciate being taken seriously.
that's well, ********, to be honest, RROD has pretty much been eliminated and YLOD wasn't particularly widespread....

Just passing through... an interesting test would be finding the determinants of large matricies of floats and ints. And I mean finding them by the straightforward stupid computation method, none of the simplification stuff.
Reasons:
1) Too large for all data to be in registers but easily small enough to fit in L1.
2) Takes a long time for surprisingly small matricies (20x20 is a huge number of calculations).
3) Stresses multiples and adds.
4) No massive-yet-trivial compiler simplifications, even for int.
5) The result has meaning.

The latter is specific to the situation.
This quote is sectioned to the event of homosexuality being concerned. However, you have to prove that woman is being obscene, which is almost impossible if you've got to find 1 doctor, 4 witnesses to event, and two family members to testify the same thing.
100 striped != death.
Adultery or fornication is VERY contentious in Islam. It is a big sin, and often breaks contracts, of nature of marriage. No death here.
...
If you're going to quote something, please be sure to complete the damn sentence... and not end it prematurely:
And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular Prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless.
In other words, be modest.
as above, adultery is a greater sin. This, though, does not demonstrate honour killing. An honour killing is killing made by family or community that the victim has brought dishonour against the family or community.
In this case, is it not dishonour, is it considered to be criminal.

I did a little reading and now am a one minute expert... :p
I've read these reactors did auto shut down when the earthquake hit. The problem is that the rods create tremendous persistent heat even after a shutdown, and it is the lack of cooling water that is causing the problem.
Yes, lack of cooing is the issue as it uncovers the core
Could it be considered a myth that any nuclear reactor can be expected to automatically safely shutdown when power to all safety systems are lost no matter how it is designed?
Not really. When all power is lost, the plant is still able to cool itself through other means
And who was saying this could not be like Chernobyl??
Chernobyl utilized a design that did not utilize many of the safety systems in place as today's plants, such as having multiple layers of containment for one...

You think they built the plant 40 years ago and have done literally nothing in terms of maintenance and/or upgrades since that time?
Do you understand what high ambient radiation does to the crystal structure of construction materials? 40 years is a very very long time in the operational lifespan of any nuclear power plant. Unless they have completely replaced the core hardware itself at least once, as well as the heat management system (which is entirely possible) the reactor could very well be in a seriously weakened state from the intense exposure. Every functional part of a plant is exposed to elevated radiation levels, spreading the material degradation throughout the system.
Nuclear energy is substantially better for the environment...
Not really. The enormous amount of energy that goes into fuel acquisition and refinement makes it nearly a wash when compared with other forms of electric energy production. When you add in the disposal of waste, both spent fuel and low level radioactive construction materials, the equation starts to creep into the red. Of course, you might be able to prove me wrong, if you could find me an example of an operational nuclear power plant built and run entirely, or even largely, with private funding.

Pretty much like a weather vein or TV aerial. Provides a couple of hundred watts at 24V or 12V. I was thinking about one for if there is ever a blackout (ie a drunk hitting a power pole, it's happened) instead of needing a petrol generator.
Every home generating 500W of their own wind power with one of these little things on their roof in a city of Los Angeles with a million homes = 500,000,000 watts. As well as a solar panel at 500W too is up to a billion watts not required from any central power source.
California is making great strides in this area. Through creative financing, tax breaks, and fairly high electric rates, quite a few people have solar. It's especially important here in the summer when electricity use is at its greatest.
However, the one thing that nobody has brought up is that evil word..... CONSERVATION
Not using electricity is a lot cheaper all around than building a new power plant, no matter the fuel source.

Dr. Spitzer is an intelligent, nonreligious psychiatrist who believes that some can change their sexual orientations.
Spitzer says it's very rare and FOF are misquoting him and missusing his study.
http://www.boxturtlebulletin.com/2007/02/15/227
Dr. Robert Spitzer Speaks Out Against Abuses of His Study
When Dr. Robert Spitzer�s study of 200 gay men and women who reported a change in their sexual orientation appeared in the Archives of Sexual Behavior in anti-gay lobbyist seized on it as proof that homosexuality was, at its core, a choice that could be changed. But as Dr. Spitzer has said repeatedly, any appears to be exceptionally rare. Just last Monday The New York Times quotated him as saying:
�Although I suspect change occurs, I suspect it�s very rare,� he said. �Is it 1 percent, 2 percent? I don�t think it�s 10 percent.�
Dr. Spitzer consistently warned that his study should not be used as a part of political efforts to denying gays and lesbians, a warning which Focus on the Family, NARTH and Exodus have ignored with abandon. Now Truth Wins Out has released a video in which Dr. Spitzer registers his disappointment in no uncertain terms:
http://www.youtube.com/watch?v=ZwE6_dLweYo
� of course, they (Focus on the Family) were delighted with that study. What they fail to mention � and it�s not, I guess, a big surprise � is that in the discussion I noted that it was so hard for me to find 200 subjects to participate in the study that I have to conclude that, although change is possible and does occur, it�s probably quite rare. And of course, they don�t want to mention that.�
(Out of) Focus on the Family
This video comes out at a time when we noticed PFOX (Parents and Friends of Ex-gays and Gays) revamping their website and pulling one of Dr. Spitzer�s statements out of context, this time in an embedded video that rudely plays automatically as soon as the page is loaded. Maybe this is the Focus on the Family video that Dr. Spitzer mentions and is so unhappy with.

Also, for the record, just because we could do it, doesn't necessarily mean we should. The free market should determine this. IF we're willing to pay more for American fuel, then so be it. If not, we'll continue buying from others... but don't let the government manipulate the markets and destroy common sense capitalism.
The free market is the part where your point goes off track. (edit - I reread what I posted and laughed coffee out of my nose... actually, to be honest, your point went off track before that, but for my purposes, I'm going to just address this one issue). If the free market were free, the decision would be made by the consumer and the consumer's money. Right?
Then, can you explain why there are multi-national oil. gas and coal companies that are responsible for almost 100% of our energy supply? Where is the "choice" for consumers? Where there is choice, we consumers choose by price, and we have shown we are willing to pay a premium for investment in renewable and/or less polluting energy. Where we don't have a choice, you find oil/gas/coal forced on us by big-oil (aka Republican) policies.
Personally, I'd love energy that was renewable, reliable and clean. I don't have the financial resources or education to develop that myself, so I and other consumers turn to our government to do things that benefit our society.
Why on earth do you support the big-oil (Republican) policies that stifle competition in the free market and prevent the development of types of energy that would beat big oil/coal/gas in a competitive free market?
Seems anti-free-market... doesn't it?

Why can't people get away from the concept of a centralized power source, like a coal or nuclear plant or even a wind farm to generate their national needs? I even see arguments that 'we don't have the space' for alternative power. Look at an aerial photo of any city and all you see is miles and miles of dead empty blank rooves. Solar panels or even small wind turbines on every single roof in every city will have people either reducing their reliance on a central power source or even contributing their own electricity to the grid to the point you may not even need a central power source, or maybe just one - which could be a wind farm or a nice clean geothermal plant.
I sure as hell would not want wind turbines on the roof of houses. The noise from them would drive me insane.
I am a fan of putting solar cells on the roof of houses and then the excess power is sold back to the grid. That helps reduce it by a fair amount. Not that it would work in a large part of the country due to not being cost effective. You need to be farther south for it to really be worth it and have fair amount of sun shine.
biggest thing is we need more efficiency out of what we have. HVAC is some of the biggest power draining system and improve those and it greatly improves the over all system.

That said, this test is essentialy a test where we do 400000000 double precision square roots which we don't even store and nothing else. There are no memory access, only very predictable branches. I have radically changed the loop and compiler flags and essentially nothing besides the sqrt() makes any difference.
I do not regard this test as important in the overall picture. It does not illustrate anything important to anyone, unless someone sits around doing square roots all day.
I might also add that designing a meaningful benchmark is very hard. I think SPEC is about as good as it gets, and yes the G4 looses in floats there too. :)
I'm in the process of figuring out vMathLib. I'm a Java guy, so all this Altivec stuff looks totally foreign to me :(
Never the less, once I get it working, I'll share the results with you folks.
Also: If anyone here wants me to try something, G3 vs G4, or whatever, aside from the square root and integer mult, let me know. I'd actually like to make full featured cocoa app full of test suites.

I'm in the process of figuring out vMathLib. I'm a Java guy, so all this Altivec stuff looks totally foreign to me :(
Never the less, once I get it working, I'll share the results with you folks.
Also: If anyone here wants me to try something, G3 vs G4, or whatever, aside from the square root and integer mult, let me know. I'd actually like to make full featured cocoa app full of test suites.

best of luck with the complications at the nuclear plant ... on top of the best Japanese engineers, I am sure some others from around the world are there to help also.
this will definitely not be like Chernobyl

They joys of an unregulated mobile industry..... being stuck with only 1 (until recently) choice of carrier, 2 year contracts, paying extra for tethering, PAYING for incoming calls (WTF:eek:).
I'm glad I'm stuck in over regulated EU. On the up side, you yanks get to play with all the new toys first :rolleyes:
Actually, you can buy unsubsidized phones and have no contract lock just as in the EU; plus we don't get charged extra for calling a cell phone from another phone - and given the calling plans and unlimited minutes between the same carrier / friends / evenings using minutes for incoming calls is a non-issue for virtually all US phone users - I'd rather have that then have to pay to call a cell phone.

Traditional light water fission? No, I'm generally against it.
Modern reactors that process spent fuel and thorium cycle reactors? Hell yes.
Writing off nuclear in all it's forms is like writing off the future of the human race, we just need to go for sensible safe reactor designs and hopefully develop fusion to the point of being a practical solution.
The vast majority of nuclear power plants are designed to produce weapons grade plutonium and uranium, these designs are neither particularly safe or efficient and there are far far better options.

I am inland of two, on the shores of Lake Ontario, one East one West, both at ~20 miles.
BUT, the prevailing wind is from the North-West, so Rochester, Northern New York will probably get the fallout.
Candu reactors (http://en.wikipedia.org/wiki/CANDU_reactor) are reasonably safe.

Can I take it then that you don't think that any of the cars on the market at the moment are worth having or have been improved at all on the grounds that they are based on an 80 year old design? "I don't think that BMW is any good as it is based on a Ford model T", hmmmmmmmm dodgy logic methinks.
You are absolutely 110% correct. We've allready dismissed BackToTheMac's outlandish fallacies though :)
I think he gets the picture now....
