Previous question: How hard could it be to take advangate of the multi-cores.
The first thing is that it depends on what you are starting with. If you have zero code out there, you can come up with a nice design for your program that takes advantage of as many cores as you throw at it. If on the other hand you have large chunks of legacy code that was written in the time of single cores, it may be close to a re-write to fully take advantage of the hardware. In some cases it will be easier in some cases to throw the old code away.
But some of it is imagination, if you can look at a problem and the solution you orginaly came up with, and using your imagination look at the problem at hand in inovative ways, parts of the programs could be re-written to take advantage of the hardware and other parts can be left alone (for the short term). This is an incremental step, you gain X% in one area and little to nothing in another area. The key is to determine what your program spends most of it time doing and re-write/re-design that section of the code for the biggest short-term gains.
I remeber working in assembler and selecting the correct combination of instructions based on their function and the number of CPU cycles it took to execute each instruction. Sometimes a set of 12 instructions was faster than a different set of 8 instructions in accomplishing the same result. Use your imagination and look at the problem from a different angle. If your brain only sees a number of serialized steps, you won't be able to come up with anything that takes advange of the hardware.
What you start with (old code) and your imagination can get you there quicker or slower.
Short answer: It depends.

nice. glad it worked for you!
and congrats to mc68k for 9 million points!
and congrats to whiterabbit for 5 million points!
Sorry you couldn't have stayed in 4th place for longer lyzardking... but at least you can claim you were there! :D And you are getting more points for the team!
And it looks like mc68k is definitly going to be our first to the big 10 mil!! You are cooking right now with over 600k ppw - as Jim Carey would say (in Mask) "smokin"!
I have now organized my machines with five (linux) in the cold basement, and the 2 win/gpu machines in 4u boxes I got on ebay in the rack with the mac. I spent christmas day, snowbound, rerouting the wiring (and cleaning the "computer room" so everything at least looks much better. I actually got 4 4u cases so I have room to grow, they were $28 each plus $17? each for shipping. 4u is about the same size as a normal tower case so everything fits in nicely. I will post some pics soon.

There has been a lot said here and elsewhere on what Apple is going to release. But let�s step back and look at the big picture for a moment and think through this process.
What we know:
1. Apple maintains the largest online movie trailer site on the internet. They have the technology to stream data in HD and they just bought a level 4 data center in March this year to storage an enormous amount of data. (I�ll get to this later)
2. HD downloads are enormous and storing them on your hard disk would fill up the disk in no time. So keeping the file for long periods of time is not an option.
3. Apple sells more laptops then desktops and laptops have a smaller hard drive with limited capacity, no one wants an external hd to carry along with their laptop, it would defeat the purpose of being portable.
4. Apple doesn�t make money on downloads, but selling the product that it runs on.
5. iPods screens are too small to watch full length movies on, and their disk space is too limited for movies (iPod nano outsells the video iPod)
6. FrontRow is made for displaying on the TV, not a computer monitor.
7. People WILL NOT PAY $9.99 or $14.99 for a download of a movie, even with a burn option. DVDs can be bought at Wal-Mart or BestBuy for the same price and you get the cover and quality you want and deserve. ( I know a few mac fans will go out and buy whatever Apple puts out, but thinking of an average person )
8. Steve Jobs said in an interview that most people only watch live action movies 1 or 2 times with the exception of animation, but music they listen to over and over again. And he hates variable pricing for content.
So what does all this mean? I think we will see on Sept 12th a streaming rental service that runs off a new media device made to hook up to your TV and runs FrontRow with Showtime as a feature on it that looks a lot like the Movie Trailer section on FrontRow today, where you see the cover designs of the movie instead of a text. (Think about when you go to Blockbuster and all you see is cover designs, and a description on the back) With this service you will be able to see the cover design, the rating, run time, the description and preview a trailer of the movie. Then if you want you can �rent� it for $2.99. After watching the movie, the content is deleted; this would work a lot like pay-per-view. For music and photos, this device will wirelessly connect to your computer to stream music from iTunes and photos from iPhoto. The device will probably sell for around $149 - $299, depending on what it can do.
But who knows� I�m probably completing wrong and Apple will release a download movie site, charge $9.99 for a movie download that around 600 MB per download and take 2 hours to download and release an airport express with video output and charge $129 for it.

I should add though, I'm glad there is an option in the mini line not to have a DVD writer, if it saves a few euros. I've had 3 Macs with them and have burnt a total of 2 DVDs, a complete waste of money.
Oh well, I've burnt so many DVDs on my PC (have I?) that my writer seems to be at the end of its life. Ouch :(
On a side note... at least with standard sized drives there is barely any price difference between combo and dvd writer... I guess Apple is really having a nice profit on the superdrives...

The Chrysler 300C SRT is a fantastic car, i think it was the summer before I headed into freshman year of college, when my buddy and i took his SRT to his lake-house. We got up to 167mph in his car on back roads, craziest/scariest/most fun experience ever. He traded that 300 in about a year ago for the Jeep SRT and man is that thing fun to drive....... Wish i could afford an SRT.:D

Microsoft have managed to get one thing right in Windows. A specific tool (Add/Remove Programs) to delete a program. That's something that I genuinely feel is lacking in OS X and this idea of clicking and holding in LaunchPad makes sense. It's imple enough: most users who own an iPhone will have no trouble in adopting this method. And what's more, it makes it instantly accessible to anyone who uses a mac. In addition, it goes a step further than Microsoft. It avoids making more novice users from having to delve in to a complex window of settings. A step in the right direction? I think so!
So personally, I think this is a very simple yet very effective change to make to OS X and should be a welcome sign of the things to come in Lion!
That's probably the most unreliable function in Windows. It's an afterthought that was pieced together when they realised they can't count on sw developers to provide an uninstall app for their sw

Ok I'm using a Late 2008 MBP model, 2.4 ghz IC2D , 4gig ram. But Launchpad is lagging for me big time, when I try to scroll thru my apps for instance. and when i switch windows its not always flowing. Now I know LION still has a few miles to go before it works perfectly, however I wanna know if its the same for other developers with later MBP's or does it flow perfectly?

I don't think the problem here is cost. Lots of people want an iPad, so this is like a fringe benefit. It's more about logistics. I don't think it makes sense to run two screens, and tether an iPad to the TV.
Heh, true, I use my iPhone as a Netflix player. Yet, I don't have to hold the iPhone to do it. I just set it up and enjoy the movie. An iPad is a nice tablet, but not a great controller.
I think a USB controller, going to the iPad 2 - that's connected to a TV - makes more sense. Then, it's like a real gaming console. Another possibility... the iPad 2 camera could be used for motion detection. Then, the gaming can be like the Wii or XBOX 360 Kinect.
My problem here is the cable � HDMI cables are usually short.
This is progress though.
I'm not bashing the iPad. I think it's cool. It's clearly the leader in the tablet market. Yet, I don't think this is the direction to go for gaming. I think the Apple TV makes more sense.
Apple TV � With a Camera � and that changes things.
FaceTime, Games, Apps on the TV.
But again, the controller is the problem. Apple is not leading here. It should set the standard, not let developers create Frankenstein gaming consoles. This isn't the Pipen. Apple has a strong opportunity to enter the game console space. I don't see a reason to delay.
Hmm - Apple TV with similar storage e.g. 32GB, 64GB, the ATV remote also acting as the gamepad (kinda like the wii control)
Games are compatible with both iPad and Apple TV (only buy once) and have the choice to play them on iPad or on ATV!!!
Sync from iTunes to put the games on both devices!
Now that would be cool - games are relatively cheap compared to consoles etc and they can also be used wit your iPhone and iPad (all Universal)

I'm glad Apple is thinking for themselves and leaving the purists behind as they adopt newer, better ways of doing things. The idea of installing from a disc image is ridiculous. Anyone I've explained it to can understand it, but always mention there must be a better way. "Install" is much better than launching a disc image, opening an applications window, and then dragging the icon over to the other window. Also, dragging a file to the trash doesn't delete all the pieces it came with. An uninstall was needed. I have been using AppZapper, but this will now be built into the OS.
There is a better way. Good programs include a shortcut to the applications folder in the disk image. Some even have arrows directing you to drag the application to the shortcut within the same window. How on earth is an installer better than that?
Apple's uninstall process also works really well. If you want to delete the program but retain the settings, drag the program to the trash, if you want to delete the settings, drag the settings folder from the library to the trash as well or use a third party app like app zapper (as you mentioned). How is the Windows uninstall process better than the one step process of dragging into the trash or dragging into app zapper?
People coming from Windows often criticize macs because they get the job done too efficiently, and they find it hard to believe that things can work so smoothly yet still be effective. They come with the expectation of expecting complexity, and when it isn't there, they find the lack of complexity to be a fault. It's a ridiculous phenomenon, but it's quite real. I should know, I also switched.

My guess is it will open UP a great deal, around $4 then drop $1 or 2, 2 hours into the day and then climb to finish up 5 to 6$ :D
Seasonally and VERY consistently AAPL drops from March to the end of sept and then rises strongly from late Aug. to Christmas. Then rises more in Jan. rests in Feb. and quickly and unpredictably peaks in March or May !?!?!?!
Some years you will make %100 playing it this way, every once in a while you might loose %10, when betting makes bets that have BIG upsides and small downsides !!!
That is the general trend of the stock market. And the US economy.
Late spring/summer... market trends flat to down. People are more interested in vacations than working.
Sept. market rallies briefly as people get back to work.
October is traditionally the worst month to be in stocks. Every major crash has happened in October.
Nov-Dec the market usually rallies. I attribute this to Christmas and bonuses/performance rating. Money managers need to boost their performance numbers for the year so they pump up stocks, usually pouring into any stock that has performed decently. It may not go up, but at least they can say they were in winning stocks.
Jan-early spring usually has selling. A combination of cashing out of the Christmas rally and tax selling.

MacOSXrumors??? There is, if anything, negative correlation between their predictions and reality.
What Apple had damn well BETTER announce then is Merom MacBook Pros. It's inexplicable that they have not done so already.
Now that Appleinsider is reporting it as well, this rumor holds more credence.
I don't think such an endeavor for a new iMac would negatively impact C2D MBP's from becoming available in the next couple of weeks, at least I hope not because that's what I really want more than anything. This possible new 23" iMac is a sexy concept though.
