ddtlm check this out, this may suprise you:
I ran the double precision test (sqtrt()) for the first time today as a c program. I compiled on the same machine as I ran the java version, with gcc version 2.95.3-5 (cygwin didn't come with 3.x).
Here are the parameters to gcc:
$ gcc -march=i686 -O3 -pipe -mpreferred-stack-boundary=2 -fforce-mem -fforce-addr -fexpensive-optimizations -funroll-loops -fomit-frame-pointer
Using this, the C program does it in 7.01 seconds. The same code, in java does it in 5.9. The javac, or the jvm seems to better be able to tear apart the loop. I think Java being "slow" is another common misconception that people have ;)
Oh well...
Meanwhile on the PPC side of things, I compiled the fp test against:
mcpu=7450 -O2 -pipe -fsigned-char -maltivec -mabi=altivec -mpowerpc-gfxopt -funroll-loops
Ofcourse this is running in 10.2, and I'm still stuck at around 90 seconds.
Is there anything else you think we can do aside from vectorizing it? Lastly, now that we're all on the same page now on how we are compiling this, I reran the silly single percision int test, and my powerbook looses out to the 750FX. Same platform, same code and everything, but heck?

Cause it's not. I played with the iPhone SDK for a test app and had to relearn a few things. For example, the + or - in front of a method, which means instance or class method (or vice-versa). I could find the right information (or Google keywords) to get it without a few bouts of swearing.
Then my company got a contract to port an iPhone app to Android. And by port I mean rewrite since we can't share anything from obj-c to Java.
Coming from a C/C++ background, the learning curve was really quick. Plus Google did a relatively good job with its SDK and emulator which work pretty well on both Mac and Windows.
For me Objective-C is user-friendly enough.

I agree: There's a place for that kind of therapy. I even know people who felt conflicted about their sexual orientation. Unfortunately, the conflict caused them some of the severest emotional pain I could imagine.
The goal of any ethical psychological treatment is only to treat the conflict that causes pain. The patient is considered healthy when his thoughts and behaviors do not interfere with his ability to lead a fulfilling life, not when he changes his thoughts and behaviors to ones endorsed by the therapist. Anything else is abuse of the patient and psychological malpractice.
To tell someone who is in conflict over his sexual orientation that he must change it to be well is no different than telling an anorexic to lose more weight so she doesn't feel so fat. It is indulging the conflict to produce conforming behavior rather than treating the conflict to produce a healthy patient.

Android is a mobile OS. iPhone is a device. Android is and will be used in many devices by many manufacturers. iPhone is only one device, but if you add iPod Touch which runs the same OS I don't think Android can surpass it by 2012.

I wonder if those people who complain about iPads not being included in smart phone market share will also complain that the iPad is included in pc sales market share?
The complaint isn't that iPads aren't being included in the smart phone market. The complaint is that there is a sole focus on smart phones when comparing Android vs. iOS market share when clearly the iPad and iPod Touch are very significant portions of the iOS platform.
This is not a "smart phone" platform battle. This is a new mobile computing platform battle. But since Android has no viable competitors to the iPad or iPhone Touch, people (Fandroids and analysts alike) conveniently like to leave those devices out of the equation.

Whats the line in the sand? Are Gay men, simply men who find other men attractive? Do they share partial brain chemistry similar to a woman? Are some Gay Men "women trapped in men's bodies"? None of the above? We havent walked in their shoes...so defining what IS and ISNT a disease is pretty ignorant. glad we're all talking about these issues though...stay well friend and keep posting! :)
As long as they have a penis, gay men are men.

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.
Obscurity IS a factor that helps Mac users. The point is that good, secure design is ALSO a factor. But DRM file distribution doesn't relate to OS security/privacy anyway.
Anyway... you still have to BUY the song to use this hack.

Found it:
"Furthermore, plans (unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/smartphone to computer accessories, BLUETOOTH� or any other wireless technology) to Personal Computers (including without limitation, laptops), or other equipment for any purpose. Accordingly, AT&T reserves the right to (i) deny, disconnect, modify and/or terminate Service, without notice, to anyone it believes is using the Service in any manner prohibited or whose usage adversely impacts its wireless network or service levels or hinders access to its wireless network, including without limitation, after a significant period of inactivity or after sessions of excessive usage and (ii) otherwise protect its wireless network from harm, compromised capacity or degradation in performance, which may impact legitimate data flows."
Interesting. All AT&T has to do is believe you're tethering and they can modify your plan? I'm going to keep tethering, and if they try to change my plan, get out of my contract with no ETF. Id also be very curious to see how the "believe" provision would hold up in court if they had no other proof than an increase in data usage. I'm guessing not very well.

No they don't, they don't see it as a legitimate threat because it has very little industry support.
Believe this all you want, when a company like Epic sings the praises of iOS you'd best pay attention. It's had great impact on Nintendo's mobile plans and it terrifies Microsoft (who are praying that Xbox Live on WP7 matters to enough people). When mobile gaming (i.e., on the iPad) is making such inroads into mainstream gaming, it's eventually going to have an effect on the way consumers view mainstream console gaming. In fact, this is guaranteed.
You're holding too fast to the separateness of mobile vs. console. Over the next few years you'll see that separateness blur, and probably faster than anyone would have thought. There will be a definite, palpable melding. It's inevitable.
The App Store opened in July 2008. Now look at what we have in April 2011. It's astounding. And we're already trying to get mobile devices to project games onto HD tvs. It's very, very telling. It doesn't matter how successful it is *right now.* (pretty impressive, actually.) The point is, you can see where we're going with it. When Apple says "move over, Xbox!" they aren't being glib or fulsome. It's a portent. Just a taste of what's to come.
A lot of people around these boards have absolutely NO IDEA what Apple is capable of and what they're about to do to yet another industry. Just sit back and watch.

The BBC is also funded by money stolen from people as a punishment for owning a television. Let's not base conceptualizations of rational thought on their behavior.
Here's a thought...
The BBC is currently tightening it's budgets and making huge cuts to try and help keep the licence fee down. People will lose their jobs due to this fact so keep your greedy opinion to yourself.
The public demand HD television from the BBC but they certainly don't realise the cost implications.
So the licence fee us now fixed for the next 5 years thus causing cuts.
The public can't have it all!!!
And btw BBC staff get the sack immediately for failing to pay their own licence fee!
Back on point, I don't think the BBC have purchased that amount of adobe licences or hardware to go with... I would know.

Companies that "ship" stuff that people don't buy do not stay in business very long. Therefore, "shipping" is a good enough estimate 99% of the time. The other 1% is quickly identified and purged from the economy.
Does this rule apply to non Apple computers and tablets?
I recall only a short time ago when non Apple companies where posting numbers, people on these forums were ripping the figures to shreds as they said they were not sold items but only shipped items.
Do we all agree the same rules for everyone :)

The need of first buying a Mac and then learning how to use it, the SDK and Objective-C will stop too many great developers from giving it a try.
Great developers are not inhibited by things like that. In fact, they often consider it a challenge. It's lazy developers that don't welcome the opportunity to embrace different technology and just too-quickly dismiss it.

HDMI has nothing to do with the down res of an image. The Image Constraint Token dictates whether HD will be transmitted over analog channels like component. The ICT has not been implemented by any studio and they have stated it is not likely to be in the near future.
HDMI sends the signals and confirms the device on either end is compliant device. How the HDCP handles the situation is up to the studios and manufacturers.
That is exactly what I said, except in plain English.
To repeat: HDMI maintains image resolution and allows the receiving device (monitor with HD Compliancy) to adjust if needed. It also maintains encryption for DRM -- I said exactly what you said.

<soapbox -- move on if you are not interested>
It's you. He's right. I could care less about the whiners who say "I need 10GB per month to tether all my devices to my iPhone." I don't like subsidizing that. If you use that much data on your iPhone directly without tethering then more power to you -- that was AT&T's mistake for offering an unlimited plan.
But the "unlimited plan" they offered did not say "unlimited devices on one plan". It was very specifically restricted to the iPhone. To those who have cheated system, I applaud your brilliance for working around the rules. But when the rule maker starts cracking down on your circumvention crying that it is "unfair" is a bit comical.
Everybody signs a contact with their carriers when they get service. They sure as heck know what they are signing up for -- some of amount of money every month for some sort of access to their network with some set of limitations.
Sure, if you buy an iPhone it is yours. You can do what you want with it. However, your use of the carrier's network is subject to a contract with specific terms. If you don't like the terms then you don't need to agree to them. But if you choose to agree to them and try to cheat the carrier through unfair practices then don't expect others to be happy about subsidizing your practice through increased rates or degraded service.
The carrier is going to make their money one way or the other. They are a corporation driven by profits. Retail stores raise prices to compensate for shoplifting just like carriers raise rates to compensate for network expansion and lost customers due to network overload from those who circumvent the agreement they signed up for.
Any measure by the carrier to crack down on those who cheat the system is a welcome effort to those who choose not to cheat the system. They could be jerks and just decide that its not worth the effort to go after those folks and make everybody pay for it.
Do I believe that AT&T will drop their rates once they crack down on the bandwidth cheaters? Heck no. Do I believe that the network performance will get better for the rest of us without added monthly fees, probably. Either way, what's fair is fair. Nobody is born entitled to an iPhone and mobile data. But the sense of entitlement in this country has gotten so out of hand.

It is a huge difference in getting to know how we can alter the genetical code and actually do it in a grand scale. THAT if anything will be our end.
We've been modifying the genetic code of organisms (plants/animals) for centuries by selective breeding. GM is a more refined way of doing these same things, but more rapidly, as well as permitting the introduction of new genetic traits not possible through standard cross-breeding strategies.
It has the potential to end a great deal of suffering in the world from starvation. Not to mention potentially huge environmental savings from reduced use of pesticides, less irrigation, and transport.
However, this immense power needs to be deployed carefully and responsibly.
