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.
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.

Dammit! Dell just dropped the price of the 24" LCD today to $679. That's a hell of a deal for a 24", I think I may have to pull the trigger on one tonight as I really need some screen real estate to work in--this is getting ridiculous working on mags on 15" MBP and a craptastic 17" LCD I stole from my wife. Then, if they drop the prices on the 24s and 30s on Black Friday I'll buy another one.
Regarding the Mac Pro, unless the mobos are going to change dramatically and they intend on adding some other voodoo hardware, I think I may just buy the 2.66 quad now and upgrade the processors when necessary.

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?

Something just dawned on me. Like when Macrumors (or someone) posted that Rush Limbaugh was selling his broadcasts for MP3 players, people here were divided. And it's the same thing with Greenpeace. We're fighting over idealistic opinions.
Maybe we should focus our attention on fighting for the Apple and all its greatness (and some not-so-great things), instead of against each other.

I'm replying just so you don't get the slightest idea in your head that you've won, or that I'm retreating. I'm sitting with my entire office laughing at your naivete and misunderstanding of what modern computer hardware is. Keep digging your hole.
Maybe your employer would like to know the entire office is slacking and on MR instead of working...... nice way to burn company time with your pathetic pecker measuring.

OK. I know that many of my apps aren't going to take advantage of this level of multithreaded power, but I can't help but get excited by this development. After so many years of sluggish improvement, it feels like we're in the midst of rapid (and radical) change.
Each process is it's own thread. And most processes have multiple threads. Unless you only always have one program open at a time, more cores always can help speed up your system.

Thanks. I do know gcc a bit, but I really need complete instructions...
i.e. What to do with the .asm. What to do with the .c. What to do with them both to finally bind those. The linker ld? The only time I've ever used ld was in my little OS development... it's been months since I've touched that.

I think the realistic expectation is: "If Apple doesn't make any more changes to the iPhone for the next 10 years, there will be an Android phone to beat it by 2020!!"
I feel like the trend is going to stay the same as it was with the G1. They're like "ooo look at our neat new features!!" Unfortunately, the iPhone/iPod just got those features, only better, just before you launched.
The competition just can't stay ahead, and Apple is going to keep it that way.

This is where I agree with you. I don't call myself a tree hugger. Sure, I love the earth and planet but sometimes people take it too far.
Sure, go and destroy this planet - you know, the thing that sustains life for you.
Hell, some people take things too far.... the entity that supports life... yea.....

I was just sitting at work, with 3 co-workers today. We were looking at a cut of footage I had from when my organization visited the capitol. Tweak this... 4 minutes later... good, but try moving that there instead... 4 minutes later...
That alone has me all psyched. This was a brand new i5 machine, too. Got in about a week ago. Being able to save 12 minutes moving a clip back and forth by .08 seconds is a lifesaver.
For what I use FCS for, FCPX looks great! With the price drop, somehow it's less money for a MBP than a comparable PC and Adobe... I'm psyched for a new portable setup come next fall!

Most people here, will tinker with FCP and never actually make feature films or shows. You all have an opinion, but I think that people that actually do this for a living will be very happy with the results.
I do this for a living and it's the same as it with Avid: everyone thinks they know it better. And in this case and in this thread it's a who is "pro" d!ck contest. Who the eff cares, rite? I will definitely upgrade to fcx no matter what these "pros" say and I consider myself an avid guy. But I just hope that this program is stable, and doesn't have that many bugs as can be expected from a total ground up program rewrite.

Well, actually I cannot understand why Apple has rejected original nano's design and has made a return to ipod mini style... IMO Ipod Nano was one of the best designs in Apple's recent history, so I am looking for a second hand one :)
Wrong thread?
Good luck getting a non-scratched second hand Nano. Every one I've seen is covered in them. Hence the redesign.
Back to iTV....

Naah. That's not it. Try again.
Um... it is actually.
Hardcore is defined as the "the most active member of a group or sub-class of individuals" used an an adjective as it is in hardcore gamer that means "the most active gamer".
Hardcore means the gamers that game the most. If you have a Mac there is a great dictionary app built in.

Most of the major power sources in use today come with major safety/environmental risks. Nuclear is in some ways potentially the most risky. However, people will continue to use it because it works.
We are only as safe as the weakest nuclear power plant, and some of the old Soviet designs still operating are truly scary. But I see a discussion over whether or not to use nuclear power as being 60 years too late - nuclear power is here to stay, due to pressure to satisfy civil power demands that will require them to remain in operation and even expand in numbers. At this point in time renewable energy sources are producing only a fraction of the energy they must produce if we are to start decommissioning nuclear plants.

SW engineers usually optimize their systems with expectations of the environment they will run in. Pro-level applications often run much better in systems that use SMP, but not all. Sometimes it is better to pipeline a few processes at high speed, rather than do a lot of task swapping. Most of Apples core customer's application seem to benefit from SMP. So, that is what they are going to expect from Pro-level hardware.
Please don't confuse SMP with multi-socket. You must have an SMP (or even an ASMP) operating system to use any computer with more than one core.
It doesn't matter if the two cores are in one socket or two - both require SMP in order to manage the cores.
Saying that a dual-socket system is "SMP" and a single-socket dual-core system is "not SMP" shows that you don't quite understand the computer technology required to do multi-processing.

As a Norwegian I can say that Apple has way more credibility than Greenpeace over here. We have seen what they are all about. Greenpeace is a bunch of spoiled city kids that has no idea what nature is.
Yeah, cause you just HAVE to hunt whales and eat whalemeat in Norway in order to survive, such a poor country with poor people. How dare Greenpeace oppose your ancient way of life?

you might want to rethink what I mean by contained ...

Contained to the plant?
Contained to the locality?
Contained to the island?
Contained in the hemisphere?

So few virus for MAC than when one appears it is news... :)
Any software for a Mac that says "MAC" in the title or in any documentation would already be suspect to me. Pretty much every person I have run across that thinks it is spelled in all caps as "MAC" has been a moron.
Moron seems rude, but yes, really no Mac user should ever get this wrong.
Really, it's whether you know the difference between an abbreviation and an acronym.
Mac is an abbreviation for Macintosh.
It's not an acronym for Mechanical Apple Computer. :o

I think iTV is a waste of time and money for apple. In essence, the mac mini can do ALL OF THAT, plus more, minus the ability to go out via HDMI. If apple just upgraded FRONT ROW to the quality of the iTV user interface, you have an iTV right there on the mac mini! Just add some more ports, including HDMI, cable in for DVR recording, a massive hard drive, and you have a MAC MEDIA CENTER PC! What about connecting to other machines to share content? YOU CAN ALREADY DO THAT!!! In iTunes you say "share my media on my network" and any computer with iTunes can read that information! Come on apple...this iTV thing is a WASTE. It's a dumb down mac mini...apple will make way more money selling mac mini's with TIGER/LEOPARD on it, so not only would you get a DVR, STREAMING MOVIES, DOWNLOADABLE MOVIES TO PLAY ON YOUR TV, but you get WEB TV!!! Or edit a MOVIE ON YOUR BIG ASS TV! Sorry for the rant...I just don't know why apple doesn't merge both technologies together in one system to compete with media center pc, and convert MORE mac sales.

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.
