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 obvious uses for a HDD to be included in the iTV have been discussed fairly extensivly. I'll try not to rehash anything, and all appologies if I do without giving credit. On to the point.
Apple is in the hardware business. They make software and provided services to generate sales and lock you into thier hardware. They make like $.01 per song; maybe $.50 a movie. So why do it? So we'll buy a new iPod/computer every few years. The same holds true for iTV. Its hardware. Apple will include anything if it makes the hardware purchase more compelling. So why the HDD in iTV? For ALL the obvious reasons. Maybe they partition an 80GB iPod drive; say 10, 10 and 60. 10GB for a "rental" service downloaded straignt to the new box. They are locked to the box and once its full you can't rent anything else without returning something. 10GB for a streaming cache from your computer. And 60GB for PRV use. Why not?

OK, does anyone know how well Matlab (7.1 I suppose) is threaded?
Have run some batch files linking 90 simulations in total, which took a few days of continuous running to complete. This is on a 2.x Ghz (Can't remember exactly) P4 at Uni. Could anyone tell me how much better a Kentsfield or dual Clovertowns would run Matlab? (only one application open at once, else its cheating) Would this change between running Matlab under OSX or XP?
Thanks in advance.

It auto-executes the installer because installers are marked as safe if "open safe files after downloading" is turned on.
Fine, so I can write an installer that will just wipe your user account while you read my EULA and you'll happily execute it because "hey, it's just an installer" ? :rolleyes:
This is not an example of shellcode being injected into a running application to execute code in user space.
This is not, but I'm interested in the mechanics because next time, it could very well be. That's my point. Some of you guys aren't cut out for computer security...

While I have misgivings about Nuclear power I do think it is a good midrange solution to our problems until we can solve our battery problems (thus enabling true renewable energy sources to be viable), drilling isn't a viable solution to anything.
The US doesn't have the resources to provide for our society on our own. Not to mention that the whole process of drilling can take decades (meaning 10+ years, not something like 20+) to play through to the point where steady production can begin. You can't just go out and drill, even if you find something you have to set up the supporting infrastructure first before it is viable.
I'm glad you understand the nuclear is a good solution. You're a bit off base regarding drilling though...
First, the 10+ years argument is pointless. Think about it. If after 9/11 we would have started drilling, started seeking out more domestic energy, we'd be producing a ton more of it today (10 years later) and our prices would be less affected by unrest in the middle east today. We'd be more secure today. We'd have a less hawkish view of war in the midwest today. Something good taking a few years to develop is not a reason to not do it.
Second, the U.S. has HUGE untapped deposits of oil, coal, and especially natural gas. And as the facts prove, it's a VERY viable fuel source.
Third, we do in fact have the resources to provide for our own society. Expand nuclear, expand oil, expand coal, expand natural gas, expand biofuels, keep investing in promising new alternatives (private investment, not government) and we could get to energy independence in probably 10 years or less. The only reason we're not doing it is because of burdensome government regulations and the fact that other countries can produce it cheaply. As prices rise, one of those issues becomes moot... 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.

These groups don't care at all about the environment. They only want to hinder businesses.
Sure, I guess calling them the greenest company will really hinder Nokia's business - or indeed any of the companies that got rated near the top. :rolleyes:
The fact is this report says something which, as Apple fans, many of us don't like. However, if there was a comparable Lenovo forum, they'd all be saying the same thing –*"the report is rubbish"? Does it make it true? No.
What if Apple still came fourth from bottom, but Dell was third from bottom. Does that make the report more credible? No.
The fact that this report is gaining traction across multiple tech sites, not just MacRumors, plus the fact that Apple speedily responded proves that the issue is real. Did Apple reject outright the report's claims and say they are actually just as good as Nokia and whoever else? Did they come out and say, "greenpeace is b/s"? No. They said "we don't agree with the grading system used, it's not reflective of our other efforts" or some such politician-esque answer.
It could just as easily have been Apple at the top if they were up to scratch with regard to the materials used in their products, then you same critics would be loving the report. For example, if tomorrow Greenpeace ran a report on the grading of tech company recycling programs and put Apple at the top, what would that say? That Apple was good in one area and bad in another so they need to do more.
Stop being fickle and naive and understand the bigger picture. :rolleyes:

Since iTV most likely wont be a DVR device, I coughed up $700 today for a Sony DVR instead.
I am sure Apple has a brilliant plan for the iTV, but I fail to see it.
iTV is a great product. If you want a DVR, buy a DVR, if you want the next level of streaming, iTV is it. I already use Airtunes alot. It is hooked up to my stereo. Anytime I'm out in the yard or having a BBQ, I just plug in the Express and some speakers out back and stream music there.
I personally don't buy tv shows and movies, but I like the idea of being able to code anything video into iTunes and view it on my tv along with slideshows, music, trailers.

Bravo, this is the funniest post ever.
I bet there's a lot of fan bois with soiled underwear.
Could it be true? Their perfect computers now quite vulnerable.
Ya gotta love it...the slap of reality :) :) :)
…and in come the Engadget trolls… ;)
Reality check is that I make 75% of my part-time communications and IT work from Windows based systems, fixing errors, virus removal, bloatware, instaling third party software such as mail, photo and calendar apps (Office), configuring their WLAN to work properly, et al.
My OS X work, mostly teaching people how to use OS X (Apple's One on One but without the noise and lack of experience from minimum wage "Creatives"). Funny how the switchers fall in love with OS X and never switch back to Windows.
Not knocking it, I got W7 on one of my 6-Core Mac Pro SATA bays and it runs amazingly. Of course, some of this is due to the hardware and drivers supplied by Apple, making it seamless as opposed to writing code for a myriad of hardware profiles…
Bottom line, both are good, but Windows would be better following Apple's lead in producing the hardware with the product, ensuring less compatibility issue and adopting EFI (Bios? REALLY?). Course this would mean millions of large businesses reinvesting in MS built hardware, and with MS's product quality/industrial design, I'm not betting on it...

I own 3 macs and 5 advices. I have a PhD in electrical engineering and designed microprocessors for 14 years, including microprocessors used in many PCs. I've written millions of lines of source code in C, assembler, C++, etc.
And most of the folks I know who use Linux or solaris all day at work to design chips use macs at home and carry iPhones. I don't know a single one of them who uses an android phone (many carry blackberries however).
Just out of curiosity, why do you suppose that is? The *NIX family? Or something else? I'd like to hear your perspective.

All the more reason for me to stick with 3.1.3 on my 3G.

Wow... was multi-tasking supported that early, or did we not get that until 4.0. It's early here in Florida and I can't remember.
But hey, if its working for you... go with it!

Please explain to me, even hypothetically, how this could be a Tivo killer DVR. As a basis for the argument, consider that TiVo (as of today) can record 2 HD channels simulteously, while watching a third previously recorded show. Plus you can pause live TV.
Elgato and Myth and all of the cable & satellite Co. DVRs haven't been able to compete with TiVo to date, what makes you thik they will be able to going forward?
How does Elgato not compete?
Sure it does:
1) I can pause mine.
2) I have a full software based one-click scheduling system
3) I can record high def content.
4) If I use two cards, I can record two streams via a signal splitter.
5) I can certainly watch a prerecorded show while doing all of the above: my Quad Core easily handles this.

Saying that the 2.8GHz P4 is no good because it is based on 25 year old architecture is nonsense as far as I'm concerned.
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.

In some areas of the US people look down on if you admit that you don't believe in God. People can be very vicious about it and at the work place it's best not to voice your opinion or the Christians will gang up against you. I've seen this happen several times.

- Grid energy storage tech needs to advance so renewables can be integrated into base load and we can phase out fossil fuels and nuclear.
The problem with this is that I don't see any huge breakthroughs in battery technology on the horizon, and the most efficient 'battery" is still water behind a dam - or the energy contained in non-renewable sources.
We need to operate on the assumption that storage technology is not going to fundamentally improve.

Fine - use the E6400 which is $224 in bulk or the E6600 which is $316 @ 2.6Ghz. The point is I would like an iMac without the LCD and all the other bells a whistles with a Graphics slot. If they can't do that for $1200 then Apple needs to pack up shop. Dell can do it for less than $1000 (Dual core 930 @ 3Ghz) so saying I'm willing to pay $200 in Apple tax is about as far as I'm willing to go.
930 is a netburst-CPU (P4) and those are absoluitely dirt-cheap these days, dual-core or not. Intel is basically donating them to OEM's these days. Not so with Conroe.
So Dell has a system with dirt-cheap CPU and that vaunted Dell-"designed" case for under $1000. And you are now expecting to get an Apple-system with kick-ass case and considerably more expensive CPU with just $200 extra?
That said, I would like to see a Apple minitower-system that uses the Conroe. It wont be as cheap as Dell, since whereas Dell might cut corners everywhere, Apple simply does not. Even their cheapest system (Mini for example) are very refined. Could you imagine an Apple-system that is made from cheap plastic (like this HP-system standing next to me)? I sure as hell can't.

Folks who are criticizing people who are expressing their concern about the new version, please read this post.
People who are expressing "concern" that is completely based on wild assumptions with no basis in fact deserve the criticism.
Really, I can't imagine anything more ridiculous than assuming that every feature that wasn't shown in this (fairly short) demo has been removed from the app.
I haven't seen a single specific on what's a step down from the previous version other than the price tag and the look.
I'm not too familiar with the FC app, but I'm wondering if this FCSX is the newer version of the previous $999 application... Why'd they drop the price by ~$700?
Part of it may be that they're switching from a bundle of multiple apps to selling them separately (or not, we don't know yet). Or maybe they just want to sell more copies and get more of the market share.
