If someone in my group had sent me a quick email with this equation I would expect to see-
(48/2)(9+3) or 48/[2(9+3)]
This is even more important when the equations I was using were a lot more complex!
Step back a bit. Someone in your group would actually send you an expression that was full of constant numbers rather than reducing that to the answer?
As s a physicist by training I hate it when the meaning is bled out of an expression, by rote plugging in of numbers. Engineers love to do this kind of thing and take a perfectly nice equation, lump a bunch of stuff together and take a few implied logs for good measure and think it still has meaning. :p
I'd expect anyone who knows what they are doing to send something like x/y(a+b) rather than 48/2(9+3). Preferably with an extra pair of parens/brackets to improve clarity. Or send you TeX $\frac{x}{y}(a+b)$ or even code if this was a numerical exercise. This would assist in your sanity checking if, for example, you saw that x was a distance, y was a time and a and b were also times and you knew the expected answer was a distance you'd know that (x/y)*(a+b) was meant. If you were looking for acceleration you might go back to the author and ask, "did you mean (x/[y*(a+b)])?" instead of taking the original expression at its face value.
In the absence of context and any other information the answer is 288.

"If you have a stick that is 3' 7 13/16" and need to divide it into 3 equal sections, what is the length of the each section to the nearest 1/64 inch?" as opposed to "If you have a stick that 1233 mm long....." - and no, I didn't check to see if they are the same -
I'd use a calculator in either example, so it's a moot point.
2) Same idea as above.... "If you have a tank filled with 450 cubic yards of water, and it is flowing out at a rate of 3 gallons a minute, how long does it take to empty?" as opposed to the metric system where 1000 litres of water is 1 cubic meter which is 1 tonne (approximately - since altitudes and temperatures affect the density of water).... but it's close enough for horseshoes....
I've never seen a tank meant for holding liquid that wasn't rated in gallons - and I'm talking about up to 5 million gallons. But still, I'd be using a calculator in either event. But to illustrate my earlier point, 1 cubic yard = 27 cubic feet, 1 cubic foot = 7.48 gallons. Simple math.

So I thought... Would apple release a phone-only? No chance. It will most definitely have music features including wireless downloads from the iTMS (including a way to put the songs on your computer)... If this rumor is true of course.
My hope is for the phone to work on the Nextel / Sprint network not just because I have a Nextel, but because they have had time with their walkie-talkie feature, and I'd imagine that that would benefit the use of something like iChat over the phone.
Ah well, only a little over a week till the big day!

If this news is true, then there must be a total revamp of iOS. I don't mind if the look of the phone stays the same (even though a larger screen wouldn't hurt) but it's more what you can do with it. New notification system, maybe live icons, file system?
I am hyped for the iOS event rather than the new fall iPhone event.
WiFi sync is a big one. They too extensive use of their "Home Sharing Network" not to have it.

3ghz Xeon = 80W
2.66ghz Xeon = 65W
2ghz Xeon = 65W
Looks like the 2.66ghz Xeon is the best bang for buck and heat.

I've been hoping for months, but barely speculated by others.....
• 19" & 22" Merom-based iMacs (current iMacs already look "old" to me)
• backlit slim USB2 keyboard
• new category: home theater component-sized Conroe-based Mac (no Cube/MiniTower; Woodcrest goes into Mac Pros)
iLife, iPhone & all other rumors seem like smokescreen.

Hard for me, even as an Apple fan, to weep too much for a company that chooses to do business overseas isntead of here in America, employing Americans.
No way. With the cost of employment here in America these Apple products would not be possible. We should be thankful.

Hi,
I've said it before, and I'll say it again. I will pay up to $5,000 for an Apple branded Tablet Mac.
You can almost have your $5K talet Mac today. Just get a Macbook Pro and one of these from Wacom
http://www.wacom.com/lcdtablets/index.cfm
and plug it into the MBP's USB port. OK the packaging is not so nice. So get a wireless interface between the Wacom tablet and the Macbook that you keep in your backpack.
I think this is what Apple will release basically a "Cintiq" with a macbook inside. Kind of like an iMac is an LCD screed with a mac inside.

Actually, the more I think about it... the more I've come 'round to your thinking. Living in a country that has (mostly) gone metric, the more children in the US that are taught a system that no-one else in the world uses makes a lot of economic sense - for us. So please, keep on giving your children hurdles to overcome should they wish to compete in the rest of the world. It's good for the rest of us. ;)
It isn't the metric system (or lack thereof) that's holding our children back; it's a lack of emphasis on science and math on the part of schools, parents, and society as a whole.
We learn the metric system in school concurrently with imperial units, and at the end of the day no one is unable to grasp the idea of multiplying by 10. What American kids can't tell you is how to find the focus of a parabola or why that would be important when designing headlights. That's where the problem is.
There is no hurdle. American students in Science and Engineering programs are able to do both without problems. Maybe being able to handle multiple systems give us a competitive edge....
There is already decent evidence to show that bilingual children perform better in school and in life (the idea being that more neural connections help intelligence), so I don't see why learning a second system of measures would be all that catastrophic.

Here's my problem with this distribution method for an OS:
I have 4 Macs in my house. Previously, I'd buy a Family License DVD and go from machine to machine installing it.
If I have to DL it from the App Store, I've got to download it 4 times! I don't care about paying for multiple licenses... I do care about blowing out my internet bandwidth downloading the same multi-gigabyte file 4 times. :mad:
There had better be a physical-media option!
Copy it to a USB drive or disc. Why would you keep downloading it?

I think Steve Jobs is someone who doesn't suffer idiots gladly. Note how he didn't say "there is no list of locations on people's iPhones", what he said was "we don't track anyone". The opposite of "we don't track anyone" is "Apple is tracking some people's movements". Do you have any evidence of this? Do you _believe_ it?
Just think about his statement. Then consider that 1. Steve Jobs is just slightly wiser and more intelligent than you and is more likely to have a clue what he is talking about and 2. Steve Jobs is the CEO of a major company and can't afford to lie in public.
You are an anonymous poster on MacRumors. Steve Jobs is the CEO of a major company. You can say whatever you like. Steve Jobs can't. Plus whatever I said above.
Well said.

Wild speculation: It's possible that, for the short term, Apple might have both Intel and ARM processors in some of its machines. Think GPU or co-processor. This would allow a "Mac" to run iOS apps at full speed without processor emulation (albeit some chipset/environmental emulation).
I use Mac in quotes because such a hybrid monstrosity may in fact be iOS first, Mac second. Somewhere between an iPad and a MacBook Air.
It seems obvious that Apple wants this sort of blending, so why not do it in hardware?

All this talk about income taxes is all the MORE reason why we need unprecedented tax reform here in the USA.
In my humble opinion, we should right now go to a flat income tax using the Steve Forbes flat tax plan, and start a process that four years from now ends all income taxation in favor of a consumption tax on new-production goods and services (the FairTax proposal, H.R. 25/S. 13). I cite the following advantages of this change:
Flat taxes are always very regressive, basically the reason why this is a bad idea, is that the people it effects are mostly the ones who can't afford it. and the rich will just sit on their money and not spend a lot and not benefit the economy.
And for the poorer people it would create more reliance on social security and medicare, because now what little money they used to have to save has been taken in the massive tax hike they would just get.
I'm not saying that we don't need reform of our tax system, but a flat tax isn't the way to do it.

I think the black MacBook is sort of the Pro version of the MacBook. I expect the MBP and Black MacBook to receive top of the line Merom processors. The white MacBook will stick with the older yonah and receive a price drop to $999 at the bottom end.

It'll be quite an action-packed WWDC, if all these rumors pan out--which of course they wont.
-Leopard preview
-Mac Pros
-new iPod Nanos
-true video iPods
-iTMS movie downloads
-MacBook Pros with Meroms
Crazy. I'm betting against the consumer-related announcements. And hoping for MBPs with new enclosure and features.
I am hoping they are going to be showing off the new pro apps. In January there were hints of something revolutionary in the FCS. The sudden price whacking of Shake leads me to be hopeful that something is imminent.

Shifting the update cycle for the iPhone is generally a bad idea. A lot of people update yearly or every other year and they will percieve an additional wait time of three to six month as a loss because they keep paying their contract without getting a new subsidized phone. Also ATT is not going to like that because a lot of customers will be without long term commitment for several month and may use the time to consider a switch to Verizon. I'm sure ATT would prefer Apple to release predictably every June. I wish ATT would offer a unsubsidized contract.
But so far it's just a rumor. My plan is to upgrade my iPhone 3GS this June but wouldn't freak out if I hade to wait a few more month. Also this allows me to see if some Android phone with 4G network comes along that bests the iPhone.

Apple's marketing strategy has always been that the PowerBooks (MacBook Pro) have faster processers then any of the iMac offerings. The Conroe and Allendale (Desktop) chips run faster then the Merom (Mobile) chips.
I'm not sure that's true. They had the G5 in the iMac and it was never in the Powerbook. When the Intel iMac was released it was running the same CPUs as the 15" MacBook Pro that was released at the same time. They are very different products so the differentiation is built in.

In this topic, people pretend to be IP lawyers to justify their own pre-held positions. Fun.
With regards to the actual topic, Apple would not win in court, but Samsung will settle for a not insubstantial sum. It really is that simple.
