What are bigadv units? and how do I run them?
I am currently running two instances using:
./fah6 -local -smp -verbosity 9
do I just add the flag ' -bigadv ' to my command above?
PS: I have a 2.53ghz MBP
the command is ./fah6 -bigadv -smp 8 -local replace with 16 for 16 cores
a MP with 8 cores takes 3+ days out of 6 so it's doubtful a 2.53GHz 2 core would do it by the deadline

Nop... consider.
2x CPUs 130W rated. So thats 260W, right there. However, no CPU consumes the rated, so it's give or take ~260W.
Each 5770 is ~108W, given two, that's ~216 W. Right off the bat we have ~476 W being consumed. Not bad; however let's look at the side where its not a dual 5770 setup.
The PSU on the Mac Pro is rated for 980 W of power, but for simplicity sake let's say 1 kW. Now, factor in the Super drive, Ethernet, Airport, at least 1 HDD and peripheral docks/cards you are looking at ~100 W. Take into account a 20 W per 1GB of memory (assume 6GB) and you've got ~120 W more. So far ~ 220 W more.
Now we have ~480 W [~260W + ~220W]consumption leaving only ~520 W left for a GPU. Currently, the HD 6970 requires 2x 8-pin connectors to provide 150 W per pin. That's 300W right off. So we are left with ~220 W in the system. Now, factor in that PCIe slot power draw at 75 W and we've got a ~145 W left over. ~145 W is cutting it too close and something will yield (yes I do realize 145 W is a lot more, but read on). Now, the sad part, we were assuming 1kW PSU which is not the case; it's 980 W meaning there will be less power, ~125 W. Now, also take into consideration no PSU is 100% efficient, hence there will be greater power outlet draw and the PSU will be operating at high voltage/amps and its life span will decrease dramatically over very high usage.
In other words the current PSU may come up short. Add to that the fact that all current shipping and past model Mac Pros don't have extra dual 8-pin connectors. They have dual 6-pins. There is an adapter to make a 6-pin into an 8-pin, but it is risky at best, big no-no.
So as you can see an HD 6970 would be barely supported on current models. Future models? Perhaps yes assuming Apple bumps to 1.1kW or 1.2kW PSU.
Take into account this was calculated assuming 6GB of memory and 1 HDD, anymore RAM (20 W/1GB) or HDDs (10W/disc) and the consumption will go up. Also, assuming nothing is hooked up to peripheral ports; like a small external drive that draws 5-10 W.
I have an 850 watt PSU in my gaming rig with a 4870x2 and custom coolers all around on the CPU, GPU, and case. I think your calculations are pretty close to correct if you wanted to run everything in the case at once. But that's not typical to run everything at max all at once. I suppose Apple might not want to get in the business of telling people it's okay to buy this honking huge GPU as long as you're not running a lot of extra hard drives and extra PCI-E cards.
But, for people looking to simply drop in a fast GPU and not have a lot of extra bells and whistles (read: a gaming rig), they would be fine with 850 watts or so, even with a 6970. Or at least damn close.
The tricky part with GPU's is that the high end units commonly exceed rated specifications at max load, so these calculations are tricky. And your point about running too close to your max is also a good one. It's fair to say that when you add up all your max dissipation, add 20% or so, and that's the wattage your PSU needs.

The top of it just does not look like it was meant to be a desktop app. makes me think of all the windows software you get how they over do the look of it.
I wonder if they'll give an option to change it. Or they could possibly scrap the new look completely if all of the developers give negative feedback. It personally doesn't bother me, but I do think they could have made it look at least a bit better.

Yep all of them are hard drives, i have 2TB in each one and then a RAID-0 with 2x2TB.
How are they connected? I've never bothered with external drives. NAS is where it's at. ;) I don't even like to think about trying to transfer terabytes of data over usb. Plus being able to use the storage from multiple machines without having to plug/unplug.
Just rebuilt mine with 3x2tb in raidz.

Imagine taking the steering wheel and pedals out of a real car and putting an iPad on the dashboard.
It does not matter how great the car is, how nice the quality of the machine, what size engine you have, it's still going to be ruined, and make you a slow terrible driver as you can't cannot control it very well using a touch screen.
People said the same thing with touch screens in airplanes yet the top-of-the-line fighters have touch-screen control. Admittedly, they don't use the touch screens as their flight controllers, but when you consider the volume and velocity of their decision-making, it shows it can be done.
I think it will all depend on what you get used to.

Renting music = Bad
Renting video = Good
Agreed. Video and music are two totally differant things. If I like an artist, I buy their music and listen to it over and over. When it comes to a movie, yes I may like to buy a movie for my personal records, that is what a DVD is for. but if I say "that movie looks interesting, I wonder how good it is?" then I will only want to rent it and BUY it later if it is good.

When you drive to/from Toronto all the time, standard just makes no sense, now that autos are much more efficient.
People do it every day, It does make sense. Everything from VW, to cobalts/G5 to trucks. Small car autos are junk, and do not have the longevity of larger autos , like in trucks. If I ever own a car (not gonna happen.). It will be a handshaker, or nothing at all.

Hi, can anyone explain me how is the Cinema Display 30" "flying" in Transporteur's 2007 setup (page 79, Part 13)? :confused:
Is he using a VESA wall mount?
Thanks!
I don't think it is flying. I think is it leaning towards the wall.

Says it's available, but from working in retail in the past in a store with online checking of stock I know that what is listed as "available" is not always accurate. But I will walk over there tomorrow and check it out, not far to go anyhow. :)
I haven't noticed that case today, they were all Griffin. They may have it there tmr, so who knows? :)

At this pace the iPad3 will come close to the PS3 in terms of performance when it is released next year...
I'm really impressed by the increasing performance of the ARM architecture. Mind you all this is coming from a tiny SoC which doesn't require cooling or any substantial power intake.
Impressive indeed!
Maybe we'll be seeing ARM based Desktops by the end of the decade... or sooner?

Now I'm starting to wonder if Apple will drop the 20" and replace it with a 17" LCD. I know that seems odd, but that would increase the gap between the 20" and 23" ACDs. There's a 7" gap between the 23" and 30" and if they introduced a 17" to replace the 20" that would make a 6" gap between the low end and the middle one. That way there will be much more of a difference between the ACDs.
Just a thought. :)

Merom is pin-compatible and costs exactly the same amount.
And you think they're going to still cost the same next month? When something faster comes out the slower thing has to get cheaper or Intel will suddenly find that no one is buying them.
Besides, it would be a PR boost for Apple to have the entire lineup 64-bit and "Leopard ready".
In an ambigious "64 sounds better than 32" kind of meaningless way. Can you think of any 64-bit-advantages that Mac mini owners could actually take advantage of?

HD-DVD all the way.
I respect your opinion, but why do you think that HD-DVD is better? The price aspect? In that case, I'd agree, but doubt that Apple or Sony would, because they always tend to try to have the newest top of the line stuff. Then again, Apple is a supporter of both HD-DVD an BluRay, which could really play out in an interesting way.

I think this is pretty awesome. I know that currently all you have to do is drag the app to the trash but it always bothers me that it could leave leftover files in Library, etc., which is why I use AppCleaner. I think having this more streamlined and comprehensive way of removing apps would be a lot better.

To be honest it may be more that those in Europe aren't looking for pure horse power as we seem to be wanting here in the US...living very well with the power of my "base" 4 banger 2003 Subaru Baja...
We don't have big blocks here in Germany. Compared to a gasoline engine, driving a diesel engine is much more fun (due to higher torque). More than 70% of BMW 7-series and Audi A8 are sold with a diesel engine. Even Porsche is offering diesel as an option for the Panamera.
Diesel engine is a nice combination of driving fun and fuel saving.

The hondas I've driven from 02-06 (including mine) have all have very good engaging transmissions.
I beg to differ. Aside from S2000 whose transmission really is orgasmic, everything else from 2002 on I've driven by Honda was average at best. I drove an '07 Civic Si which was ok but nothing spectacular as well as '06 Accord V6 with manual. That one had a vague shifter that looked like an afterthought. Didn't like it. My daily driver is another Honda (Integra GS-R) and that car has an excellent shifter. But it was designed back in early 90s.
Another crappy shifter award: Subaru. Most Imprezas/WRXs I testdrove recently sucked with a passion. Only exception was one with the short shifter kit.

I think that these two quotes from Tim Cook during the last Apple quarterly call, put the nail in the coffin:
"We've got the largest app store ..."
"... iPhone's integrated approach is materially better than Android's fragmented approach, where you have multiple OSs on multiple devices with different screen resolutions and multiple app stores with different ... "
Since Apple itself uses the word generically, I don't see how anyone can argue that it's not.
Isn't this what Amazon filed recently?
There are some interesting reads about trademarks on Wikipedia. I think one of the reasons Google doesn't want people to use the term "google it", is because it makes the trademark generic, and they can lose it.

When senators weigh in on privacy issues like this, they betray their foolishness. A litlle study by their aides would reveal what a non-issue this is. Sen. Franken would do better by investigating our own government's spying on its own citizens under the cover of the Patriot Act.

The vexing part of that is that the cost is largely artificial - i.e. taxes. Popular pickups like the Ford F-250 have been available in a diesel for years, and because they are trucks they are allowed to use diesel engines that are far more polluting and sooty than they need to be, and are tuned for torque rather than economy - meanwhile Volkswagen has to jump through flaming hoops in order to certify a diesel in its passenger cars, meeting stringent emmissions standards. And yet how many huge displacement V6/V8 diesel trucks are sold in the US each year vs diesel VWs? It's all about arbitrary regulatory nonsense.
It's a small thing, but also in diesel's favor is the increased range you get from a tank of fuel. So while the cost savings isn't much because of the fuel tax, you still get to go farther.
The heavy duty pickups are generally exempt from light-duty emissions and noise standards, so that's how they get away with it. I agree that it is an unfair advantage. I'm not saying that heavy duty trucks should meet the same standards as cars or light duty trucks, but to have them largely exempt and not counted toward the manufacturer's CAFE standards is a bit extreme.
Anyway, here is my point on the diesel vs. hybrids: After a quick glance around the web, I see the Toyota Prius stats at $23,050 and is rated at 51/48 MPG. The 4 door Golf TDI starts at $23,885 and is rated at 42/30 for the auto. Given the differences in mileage and difference in fuel prices, it is really hard for the average buyer to justify buying a diesel. Yes, I have read all over the internet about people getting insane mileage out of the diesels, but most people are just going to look at the ratings and compare that.
