ddtlm,
I have my theory as to why java took the lead over C in the sqrt example. There is quite a common misconception about Java that it's always slow, and there is a reason for it. Back in the early days prior to 1.2, it wasn't uncommon to see something like we did here run 10,20, or even 30 times slower then C. VM's today (1.4 /w hotspot) are much smarter than they were years ago. IMO, Hotspot makes the conventional "just in time compilers" look like a thing of the past.
Anyways, when you really think about it, Java really has an extra card up it's sleeve. Sure we tell GCC we want max optimizations, (03, etc), but GCC is limited to compile-time optimization. I think since java has adaptive runtime optimizations, specifically hotspot, the runtime optimization is what really makes the difference.
The reason why it's called "HotSpot", is literally because it looks for "hot spots" by profiling on the fly at runtime. Pretty cool, huh? Your first adaptive optimizations kick in second time the loop is ran. Not to mention the conventional JIT optimizations... code will natively compile and so you eliminate the costly overhead of bytecode translations.
Lastly, I am going to do the matrix operation you spoke about, I have to finish up some course work, so I may not get to it tonight, but as soon as I can devote some time to it, I will.

True, but the total deaths from Chernobyl are unknown. Many people dying in Russia, Norway and other affected countries from cancers or other conditions caused by the contamination aren't included in the totals.
I would still place automobiles as at least an order of magnitude or two greater. No contest.

I tried installing the android sdk, it is the usual linux crapfest of having to fix and tweak everything. After 1 hour I still could not get it working. Absolutely appalling, makes me wonder about google. Aapl wants max lockdown on all their **** but at least it works.

I find it rather surprising how blindly people here defend Apple, even after seeing how they remove your rights little by little. How many times can you burn your iTunes-songs to CD? It used to be ten times. But Apple reduced it to seven.
As I recall, the limit is on how many times you can burn a specific playlist. You can burn a song an unlimited number of times. This is a big difference.
manu chao said:If you go to a concert, theatre play, any kind of performance or into any of fee-charging class or course and smuggle yourself in through some kind of backdoor without paying for the ticket or the course, did you steal anything?
This is an excellent analogy, manu chao. Everybody knows that it is wrong to sneak into a movie theatre, but for some reason people think it is OK to copy music illegally. It is just bizarre.
It seems to me that the issue is pretty darned simple -- as a potential user of iTMS you know what the rules are. If you don't want to abide by the rules, don't use the service. Any talk of "it's actually helping Apple" or "it's my music to do with as I want" is just self-justifying bull. If you don't like the rules, don't play. It's really that simple.

That's completely false. The current installed base of Macs is around 100 million, and it grows by over a million Macs per month. You don't need a certain percentage of market share for a useful botnet; you need numbers. You talking to a handful of hackers is hardly conclusive. I can interview a handful of people in my neighborhood and find a consensus on any number of falsehoods. Get some facts (rather than making stuff up) and then re-join the discussion.

will be higher now...but not massively so..

As I understand it, Safari will open the zip file since it's a "safe" download. But that doesn't mean it'll execute the code within that zip file, so how is this malware executing without user permission?
malware doesn't execute without user permission.
it relies on tricking the user into giving it permission to run, striking at what is typically the weakest link in any computer's security: the user.
any argument that XX isn't a threat, because it requires users to take an action in order to be truly dangerous, is a flawed argument, because in general, users are stupid, or at the very least, careless.

Yeah... Kinda disappointing. Although, my 3D rendering work will benefit just fine from them as while it's CPU intensive, it's not bandwidth hungry and the software itself isn't all that great for thread scheduling, so it's better to run multiple software instances for each CPU/core. I'm curious to see how the Clovertowns compare to the upcoming AMD quad-core chips, which have full 4-way shared data pipe and L2 cache. I think it's going to be just like the AMD X2 vs. the Pentium-D all over again. AMD will hold the quad-core performance title until Intel releases their 45nm process chips with all 4 cores being fully linked. But such is the way it's been for the last few years, AMD and Intel continue to play leap-frog. Which is great for the consumer as it drives CPU tech ahead so fast... Too bad my wallet can't keep up. :(
Seconded, hell, my Mac is an OLD Digital Audio G4, and my PC is Northwood Pentium 4 HT processor. :o :o

The Judaeo-Christian God has certain attributes which I listed. Does this Ugaritic God share the same attributes, ie omniscience, omnipotence, omnibenevolence?You can give a god any attributes you want.

Blow me ATT.
Netflix non-stop for the next month
And this accomplishes what - exactly?

It's easily possible for a European atheist to not be exposed to religion, grow up happily with their own set of ethics and morals, and never be challenged over their lack of belief. Intellectually lazy? Not really... why should anyone have to jump through hoops to prove the non existence of a god?
You're quite right, and I agree that people are free to believe whatever they want. However, if they just believe something because "it's always been that way" or some other arbitrary reason then I don't have to respect them or take their beliefs seriously.
I've found the response of some of the devout atheist posters in this thread very interesting, some of the others are of the "God doesn't exist, meh" camp, who I just ignore.

Nope, sorry, no fun "regardless", for others have a dim view of any speculation outside their own pre-conceived notions.
It's no more "fun" than arguing that one knows that God exists or does not.
I was referring to the believers.

Good to know, since I'm not waiting till Q1 to upgrade. Could you elaborate on why you think that.

The new Macs are not slow computers, sure there are some PC's that are a little faster and win the old GHz race, but when you make a purchase you have to look at the entire picture.

I don't think many people here are making Apple's computers out to be pieces of crap. It's just tough to say something like "Apple's computers are about the slowest there currently are" with any sort of tact.
I would also disagree somewhat with the paying more for quality comment. I don't think you really pay more for quality when you buy a Mac. What you do pay for is anyone's guess - software, R&D, or whatever - but Apple is notorious for its very high margins. Whatever you pay more for, it's definitely not the hardware, because most (all?) Macs are made in the same massive Asian factories as the big PC manufacturers' are anyway.
And I disagree that all PCs are crap as you say they are. Windows has come a long way, like it or not, and PCs are not the BSOD-every-hour computers they used to be. They've gotten a lot better in recent years, and this is why so many Macrumors posters are worried and yelling at Apple to get a move on with the faster machines.

All this is just a more convenient way to get the same result as running your purchased music through Hymn or JHymn. It's not quite the same as burning and ripping a CD though, since that is lossy.
It's not really the same, because Apple will know (most likely) who has use this software to violate the TOS. It's pretty much like I said earlier:
It's almost like you were planning of going online to one of the illegal music sharing sites, documenting your activities, and then sending that information directly to the RIAA with your name and address with a note asking them to prosecute.

either i'm missing the point of this iTV thing or people in america have ridiculous amounts of money to throw away and are willing to pay for tv shows which are free so they can stream them to their iTV box and watch them that way. it's a super efficient way to burn money, but not to watch tv shows. dvr please.
i mean.. i do understand people want frontrow on their tv's, but it seems like an inital craze thing. i'm not going to completely knock this product though, because if anything it's a starting point for apple to infiltrate your living room, and then releasing dvr functionality in the future. we'll see.

That's kind of my point - the UK committed (or was committed) to unrealistic goals and will fail to meet them. Anyone can commit to anything - actually delivering on those commitments is completely different
Well that's more to do with Blair being uninformed and making decisions because he likes to sound better than he is. If Blair hadn't been a pillock and stuck to the realistic, achievable timeline that everyone else stuck to, then it would have been achievable. Why he said we'd double those targets is beyond most people except the monkey labour spin doctor that suggested it.
What the Greenpeace report is saying, is that Apple don't even have a strategy (timeline) for restricting material use (bar legal restrictions) and that is a black mark for the company when compared to a company that does. it's doing what it has to do, not what it should be doing if it wants to be considered the best. Dell is similar to this but is further along.
This is also related to Apple's almost nazi-like paranoia about secrecy which is harming its reputation on several fronts.
As has already been asked on this thread, why couldn't Apple release details of all the materials is uses or equivalent detail to other manufacturers? Why couldn't it be pro-active and understand the impact it could have (like putting it up at the top of this report)? perhaps because it's not actually as all conquering/superior and clever as it likes people to think?

I think a few points of mine should be made.
A.) I am sure at least 50-75% of Mac users today, used to be PC users, and of that 50-75% I believe is a more 'aware' group of users, not exactly what the media and PC fanboys try to paint Mac users as. ( dumb, needing simplicity, old etc)
B.) I firmly believe that as a technologically aware group of people, we understand viruses, malware, how they are put on computers and we can see the difference between spam, popups, malware and the lot.
c.) keeping both point A. and B. in mind, the reason Mac's are less likely to be infected comes down to the users. We know what to look for after years of using PC's by force or by choice, and Mac users know what not to download, what sites not to visit etc. This has mostly to do with the quality of users, not the software. All software, all os's can be compromised, but its the user that allows such things to happen, and it doesn't happen all too often to Mac users. Something can be said about that.
What the PC crowd would like the world to think is the only people who use Macs are uneducated, or old people who don't understand computers. I call BS, I know almost nobody who uses a Mac, a few but all of the older computer users I know, use PC's why? Because they Don't understand technology and they see a 200-400 dollar computer solution just what they need. I am sure to a older less technologically adept person, either pc or mac would seem overwhelming.
That ALL being said. My main point is, infections of computers are %100 user responsible. Why do Mac users get less infections? My belief is that the users may be of higher quality, ONLY because of the computers niche-like nature and most Mac users are dedicated, technologically knowledgable.
