I wonder how much of a performance boost (if any) there would be if someone made a whole operating from scratch. Totally new compiler, new programming libraries, new everything to take full advantage of all of today's technologies. This would take several years and hard work, I know, so don't flame me.
I was a programming major in college (though I sucked at it). I know that a lot of the libraries I used in it (like iostream and string) have been around since the '80's. Back then, consumer computers didn't have 4 core, 64-bit processors and high end video cards and broadband internet. While the libraries have been updated a little to work, they're not optimized for all the new technologies we have now.

Let me steer this off topic real quick. I have read before that Apple has two OS teams so "in theory" Leopard would, in fact, be Panther 2.0 and 10.7 would be Tiger 2.0. Again, in theory� Can someone clear that up?
Nope. Here's how it works, usually (not saying this is what Apple does, but nearly everyone else does this, so ...). You've got one master codebase, called the "trunk." Everyone works with that. When it's time to start working toward a release candidate, you copy off the code base and create what's called a "branch."
Changes to the trunk are rarely back-ported to the branch (it usually depends upon whether they are bug fixes or new features; bug fixes, often are back-ported if they aren't risky; new features almost never); any changes to the branch which are relevent to the trunk *are* ported to the trunk (since most of them are bug fixes, and the rest are probably new features whose loss might be noticed in the next release).
The branch keeps being used by one team that is working on, let's say, Tiger, right up through the release and during maintenance (10.4.1, 10.4.2, 10.4.3, etc. are all from the branch, not from the trunk), while another team keeps working on the trunk until the time they branch (10.5 Alpha) the next release (let's say Leopard). When the newer branch hits release, one of two things happen: either the team that did the development on the new branch continues doing maintenance (10.5.1, 10.5.2, 10.5.3), or the group that was doing maintenance on the earlier release does maintenance on the new branch and the folks who designed the new branch go back to work on the trunk until it's time to branch again (10.6, let's call it Lion). Both methods have their advantages and disadvantages.
I'm guess this it what is meant by "Apple has two teams working on OS X." Two teams, but only one code base trunk. And thus 10.4 is derived from 10.3, not 10.2.

PS, that isn't hard :rolleyes:
I just noticed that you are the same person I just (imho) shredded in two different posts above. Care to make a stand against anything I said as a direct response to your points? Or are you just gonna feed off someone else and reiterate yourself again?
I don't have time to answer your lengthy response point for point at the moment, maybe later tonight.
So, since my subjective opinion means nothing to you, I offer the following reveiw for your consideration from AnandTech. They compare the Apple and Dell 20" monitors. The link is the last page which has the conclusions, you can read the whole thing if you like.
The short of it is, in their technical opinion the Dell is better than the Apple. What's that? A "consumer" monitor is better than a "pro" monitor? Say it ain't so.
http://www.anandtech.com/displays/showdoc.aspx?i=2400&p=11
So, I'll stick to my guns and say the Apple 20" monitor isn't worth the price they are asking, and they are keeping it high it to encourage iMac purchases over a mini/cinema combo. It's only an opinion. I don't mean to come off like I know more than I do. My opinion is based only on my experiance with both monitors and my own decison making process based on price and budget. Since we can't see the actual sales numbers there is no way to prove/disprove anything.
Oh, and the Dell was purchased for me by my work, the Apple by me for my home.
And just a funny aside. The Dell was stolen a few months ago by theives who broke into our offices. They took our Dell monitors and a Dell Precision workstation but left my $2000 Powermac G5 the Dell monitor was plugged into. Go figure. :rolleyes:
I got a 23" cinema to replace the Dell.

Congrats to designed for reaching 1 million.
yes, congrats to designed for 1 million points!
and congrats to you, whiterabbit for 11 million points!
but why is it not showing you hit 11 million points for the team?
I'm assuming that frame times refer to the steps FahCore reports? If that's the case, they seem to be around the 33 minute mark to do the 1% of the bigadv-package.
yes, each frame is 1% of a WU. 33:00 is pretty good. keep it up!

me too. i can easily picture them sitting behind the screen biting their nails while hoping new mbp's are not released. then they have the incredible urge to post totally useless comments because they can't bare the fact that their mbp is about to be outdated.
haha! i love it!

Ok let's not argue about gay being a choice or not again. What's the point? We just had this argument 2 pages ago and the person who thinks it's a choice usually just feels outnumbered and backs out, and rightfully so. Their opinion is wrong, they may realize it years down the line, or they may not. Either way, their side is losing. Bigots always lose in the end in this country, and they know it.

Just got back from Mexico and during my time there had a run in with the local police. This is common as hire cars have different colour number plates so the police can easily pick you out of a crowd. Apparently we were 'speeding'. It's all fun and games though. I got the fine down from about $400 US to 1000 pesos. We were warned this would happen when we arrived and should just look at it as an extra 'toll'. I could have probably got it down lower but it was hot and we had a long way to go still.
At the end of the negotiation you get a form to sign with how much you paid and then you have to sign your name. The document is cleary made in something like Word and it's in no way official....I signed it Ben T Copper! :p
Well that explains their new police cars lol

Does anyone really think Apple would do a major hardware update without a press conference of any kind?
Depends what you mean by major hardware update.
The iMac was updated without a press conference of any kind. That update included C2D, brand new larger screen model, FW800, much better video cards (at least as an option) and better speakers. I'd call the release of an entirely new model (the 24"), and processor and other updates across the line, a major hardware update. And that happened with no conference of any kind.
The MacBook (non pro) was released without any event or conference. That update included a completely new enclosure, new processor architecture (and obviously new CPU), increased screen resolution, brightness... well, it was a whole new machine. And again... no press conference.
I'd call that a major hardware update. I guess you must have a different definition of major hardware update... although I can't think what could be more major than the silent MacBook release, which was a completely new machine.

So long as iTV can reliably pull all of our media content from our PC/Mac, without it overloading iTunes/iPhoto, we'll be happy.
It may just be what's needed for us to finally replace our decaying 19inch TV for a widescreen 26inch LCD TV. :)
Since our DVD player's pretty knackered too, I was thinking it'd be nice to stick a DVD in my MacPro and have iTV stream it to the front room, one less box to worry about. Built-in DVR would be sweet, no more VHS machine, but it'd need a Canadian TV-Guide.

I'm still not toally sold on the whole iTv thing. Hopefully an apple TV would have one of these built in. $299 seems very expensive for such low quality files.

I'm about ready to buy a 20" iMac but I want the new OS. How long do I have to wait?
I dont know for sure but isnt an OS upgrade with apple like $25 a piece in a family pack?
Why dont you get the computer you want now and in 6 months shell out the extra few bucks for Leopard.
Remember they arent Microsoft that charges an arm and a leg for windows.
p.s. This seems obvious. Am I missing something?:confused:

My last electric bill was $299 and change! A lot of that was because its been so damned cold (and my little old house has no insulation in the walls), colder and more snow than in many years. Folding uses power but helps with the heating :p now if I could just get those gpu's to glow a little brighter red I could turn off the furnace...
And congrats to everyone for keeping up and making points!
Hey, mc68k I might catch up... soon :D
I wonder if some people have moved to other teams? Maybe they start out with us but find another team that that appeals more to them?? I've thought about jumping to Dawkins team but it would take awhile to get where I am here so I will stay, for now at least :eek:

I have no money either. Thats why I'm just going to watch, get goose bumps and feel all warm and fuzzy inside :D

Im really looking forwards to this, if the 8-core 2.66 Macpro its going to cost just a little more than a quad 3ghz Macpro, im going to be buying as soon as it hits the website...
As a recent Mac switcher, coming straight in with a base spec macpro(4x2.66/4gb/1750gbHDD), im now happy to invest in a more powerful machine.
My only concern is the heat... my current Macpro runs 24/7 and 95% of the time is at full load across all 4 cores... and its still silent with temps never going over 52c... will these quad core chips run much hotter, meaning the front fans have to spin faster/noisier to keep the machine cool?
Given your current machine, you might consider just swapping in new CPUs. :)

All I want for MWSF is a new keyboard, because it's time we had some media buttons. And a paint app so that I don't have to buy Photoshop if I want to doodle something.
Lunja, people actually use media buttons? :eek: I wonder, do other people here want this? I specifically don't want it. I like the way my wireless kb looks now.
Anyway, the paint program thing is one that thousands of switchers comment on. I do rather agree that there's no good simple answer to that one. Not that Apple shouldn't just bundle something simple, but apparently one MR member went so far as to write the thing himself (http://forums.macrumors.com/showthread.php?t=159877&highlight=posterpaint)! :eek: :D
