This is the stupidest POS news. AM I RIGHT? Can't buy an iPhone ONLINE in NY for a day and something is interesting about this? I can't believe CNBC is so anxiously awaiting tablet and new iphone news that they think this is significant.

All right, so first off, download iMemory Enhancer from the insanelyi repo. If you don't have it, go to Cydia and then Manage>Sources>Edit>Add>repo.insanelyiph0ne.com.
After downloaded, respring your iDevice.
Then go swipe your status bar at the top for the SBSettings. If you don't have it, download it from the Search icon on Cydia.
Then when you're on the SBSettings, click "Processes", and then "Free up memory". Then, look at your available more at the bottom of the SBSettings. It should have more than it had before.
Good luck! ;)

Massachusetts Sen. Scott Brown (R) said Tuesday he does not support a GOP proposal to slash funding for Planned Parenthood, saying the cuts go too far.
Brown is the second GOP senator to oppose the measure, which House Republicans want to attach to a long-term spending bill.
"I support family planning and health services for women," Brown said in a statement. "Given our severe budget problems, I don't believe any area of the budget is completely immune from cuts. However, the proposal to eliminate all funding for family planning goes too far."
House Republicans have pushed for language cutting $300 million in federal aid and grants to Planned Parenthood, which provides abortions. The federal Hyde Amendment prohibits federal funding for abortion services, but anti-abortion rights activists and conservative lawmakers insist federal money that goes to Planned Parenthood for contraception and other reproductive health services could help indirectly fund abortions.
It is not clear from Brown's statement whether his opposition would lead him to vote against a spending bill that included the ban on Planned Parenthood funding. Brown voted in early March for the House Republican long-term continuing resolution that contained the cuts and did not specify how he would vote if it came up again.
"As we continue with our budget negotiations, I hope we can find a compromise that is reasonable and appropriate," he said.
Sen. Lisa Murkowski (R-Alaska) has also said she opposes cutting off funding for Planned Parenthood. Sen. Susan Collins (R-Maine) has voiced support for keeping funding for another family planning program.the hill (http://thehill.com/blogs/blog-briefing-room/news/151205-scott-brown-gops-planned-parenthood-cuts-go-too-far)
I think maybe if you're cutting 4 trillion from the budget, every single item would be effected. If we cut defense spending does that mean we want to be attacked?

i actually think apple will probably come up with something that takes existing features/wants/needs of current smartphones/3G phones/etc. and defines/redefines the category somehow, much the way the iPod, while still doing things other players did when it was released, defined all HD based players after it.
You're right, of course. I neglected to mention that in my post, and now that I think about that, maybe they will turn the tide on the current cycle of constant update/refresh.
Generally, Apple's products are true innovations. One would only hope that the iPhone would follow that track record.

Sorry, I wasn't trying to change what you said or anything, I was just using what you said (that the list would become quite long) as a reason for why we should reduce the total amount of articles by merging articles wherever possible.
I'm not sure that reducing category sizes is a good reason to merge articles. We shouldn't do anything that makes it harder to find something within an article once you're there, especially since categories are just one way to find articles - in fact, just 2% of page views in the Guides (of actual content pages, excluding things like the search page) are for viewing one of the root level categories.
They're split off from the main software category because of the perception that a lot of users may not want to look at the Terminal... it does reduce the amount of articles in the main software category.
I wasn't the one who created the Terminal Commands category, but I'd be very surprised if that was the reason it was created. Again, these articles are in a different category because it's a logical grouping - no different to similar categories such as Games and Networking and Internet Software. As someone who uses the Terminal extensively, I find it much more useful this way.

If you want just the email account then yes, .Mac is not worth it. That's the point. .Mac is more than email, and if you want an email address, get Gmail and hook it up into Mail.app....
Are you saying you're happy it costs $99? You don't want to pay less, no? :rolleyes: The more complaining and bad feedback we give Apple that this service is simply too expensive the better, and the better chance we have they will begin to pay attention to loads (http://www.google.com/search?client=safari&rls=en&q=.Mac%20too%20expensive&ie=UTF-8&oe=UTF-8) of posts/blogs/and stories on this. I feel sick when I have to tell someone how much it costs. I mean they say .Mac syncing is included! You have to pay to sync computers that you payed money for, and worse still you have to give it to the company you bought the computers from?? Give me a break! GMail is free too. iWeb provides little bandwidth, and the whole this is wrapped-up with a tiny storage package. And I don't think the solution is for Apple to give us more storage. I would prefer a cheaper price to more storage any-day. If you want moe storage then you pay $99, otherwise this should cost no more than $49 per year. At the VERY MOST!!

This just goes to show that Apple is in reality no better than Wal-Mart (who may be trying to thwart iTV) and Microsoft (criticized for monopolistic practices).
I wish Apple Corps (The Beatles) would sue Apple computer's pants off for infringing on their name.
:Crickets:
Apple records have been suing apple computer for about 25 years, ever since the first apple computers were capable of producing sound.
Second, that's a dumb thing to say because the two companies are in different markets. It would be akin to a company named Slithe Manufacturing which made car parts suing a company named Slithe Bakeries. There is no place in the world for hollow logic like that.

As a mechanical engineer, I'm not exactly cynical about this application of Eneco's technology, but I remain very, very skeptical. With such a relatively small temperature difference, I would say it is very unlikely that such a device would be economically feasible. A quick visit to Eneco's site shows me that they don't even have lab data for temperature differences of less than 100 deg C!
They obfuscate the issue of efficiency by referring to the Carnot efficiency to inflate the numbers to the uninitiated. Sadi Carnot showed that an ideal heat engine that operated between two infinite reservoirs at temperatures, T(hot) and T(cold) would have an efficiency of ( T(hot)-T(cold) ) / T(hot), and the temperatures have to be on an absolute scale like Kelvin or Rankine. The "Carnot efficiency" compares the performance of the system in question to this ideal heat engine.
Suppose you ran your chip at a very warm 90 deg C (363 K) and could dump the heat to your 25 deg C (298 K) room, your perfect efficiency would be about 18%! This means that for every 5W of heat you dissipate from the chip, you get a little less that 1 W of electric power. Something with an impressive-sounding 50% Carnot efficiency would really have a measly 9% real efficiency.
Unless Eneco sells these things very cheaply and makes them very small, I can't see Apple going through the trouble and expense of adding them to their portables for such a small benefit in recycled power. I remain skeptical, yet open-minded.

I've never had any issues with the latest updates, so I don't really care with 10.4.8...but I wish Safari could be less memory-hungry, or use less virtual memory...that's all.Me too. And I wish Safari had a "Sure you want to quit?" dialog box for those times when we accidentally do a Command + Q in the dark when we thought we were doing a switch application Command + Tab.
Glad to hear it's in Leopard. But having to wait for an entirely new system version to get a little helpful dialog box in one little application seems like an expensive unnecessary delay.

Maybe this should be a new feature for the folding widget: to look when you will be overtaken by someone or when you overtake someone.
Actually, I should be able to do it, you would have to choose your targets yourself though. I will not be able to provide you with the closest threats and/or overtakes, but if you know who you want to track, it's not that hard to show/calculate.
I'll first clean up the code, add detailed stats, Then i'll redesign the layout and incorporate the threats/overtakes (this might take a while - busy period @ work).
Now if someone would post this widget in this (http://forums.macrumors.com/showthread.php?t=128541) thread i'd be a happy man. I would do it myself, in fact i almost did...

""They're going to see it all eventually so who cares how they get it." Which seemed to be about web content, said the tipster."
How can that be interpreted about web content ? :confused:
How can it NOT be? Maybe not web, but it was obviously about content I would say!
Now thats a publicity stunt if ever I saw one!
Ya, actually one of the first things that popped into my mind about this is that it was planned to help both companies images and relationship seem better in the press!
He rich, yet he wears the same thing every day?
He's very into simplicity and minimalism, just look at the way apple products are designed. I think its a conscious choice to wear a simple black turtleneck and jeans, even though he could easily afford any clothes he wanted.
Yes, it is a conscious decision on Steve's part. Kind of cool if you think about it. Not my cup of tea though haha :D Honestly, it seems weird whenever I see Steve dressed in anything BUT the black turtle neck and blue jeans with his New Balance sneakers lol!

I have used a Moto Xoom. Honeycomb requires you learn a new user interface. Instead of a nice seamless experience where you can get right in to using apps, you have to learn about the literally 3 or 4 different ways to trigger, dismiss, and access apps. If they're utilities, they're accessed one way. If they're apps, you've got an app menu and a desktop-style metaphor to try-- either works. It's confusing as hell. I mean, you can LEARN anything, but why would you want to.
Bottom line-- a Xoom is $800, it's far less functional, and it's far more confusing to use.
imo, if you've used any type of gadget before.. it's pretty easy to learn honeycomb within 5 mins of using it. hell i find it easier to use than a vcr. i think that some apple users, and i'm not saying you specifically, are just so used to ios or osx, that in a way.. before even trying out a new device.. they already pre judge it or are even biased.
i don't agree with your statement about the desire to learn new things also.. a lot of people love gaining new knowledge. why would you limit yourself like that? just years ago, i knew most things about how to efficiently use windows os, but my curiosity to learn osx made me a mbp owner.. you learn that some things have their purposes and usefulness.

dropping motorola has been something more mac users here have pondered, but we will have to wait and see if ibm can truly deliver
the latest powermacs may not be as fast as was rumored but they are a good step in the right direction
when apple has no more machines in the sub 1 ghz range, then the complaints will definitely slow down, and once apple has a machine over 2 ghz sometime next year, then the speed issue will not be at the top of the list...of course, the pc world will be over 3 ghz at that time but hopefully not at 4 ghz...so it's our dual 1.25s vs. wintel's 2.5 ghz p4s and that does not look too good
so if we can scale up to 2 ghz while pcs are not at 4 ghz yet, then it won't look as bad or matter that much...and maybe then the major switching will start to begin en masse...i will keep my fingers crossed
i think apple's goal is to get more users, not to beat microsoft...at this point, no one could beat microsoft
when asked who would be the next microsoft, one of the financial brothers of the motley fools (business book series) said the next microsoft is microsoft...pretty obvious stuff
at one time, i thought dot.com would grow even more placing much more IT/IS emphasis on WAN making cisco systems become the next microsoft but that did not happen and cisco is not in any position to take on the mantle of a microsoft

This is nothing new...
I used those devices in last year for my GCSE courwork (15-16 yrs old). I used them in a drinks cooler / heat thingy.
I won't ramble on about my product, but: The devices are called "Thermo electric coolers. i.e. TEC's
And they offer 3 functions.
1. The cool something.
2. They heat something.
3. They produce electricity.
This heat / cooling effect is called the Peltier effect (some French guy) and some people call these things peltiers etc.
They work, buy passing a relativly large current 3-20 amps, depending on wattage. to draw heat from one side to another basically. one side is -10 degrees c. The other is +80 degrees c. However, if you don't power them and instead create a temperature difference, i.e. stick ontop of a hot computer chip. You wil have set up a temperature gradient. So it will generate electricity. Typically you get around 4ma per 1 degree C. So nothing huge, unless they have refined them. So in this case, the bigger the delta T, the more power. I guess it could power a fan then! Seem's easily possilbe, but I wouldn't expect battery life to be much more than 30 mins at most extra. As 1 fan doesn't draw THAT much power!
Still a good idea though!
If anyone else has any questions, on how they work, images, tech drawing, or my product, i'm happy to answer them all!
BTW: Forgot to add, the generating electricity idea, from one of these, is called the "Seebeck Effect"

I won't ramble on about my product, but: The devices are called "Thermo electric coolers. i.e. TEC's
And they offer 3 functions.
1. The cool something.
2. They heat something.
3. They produce electricity.
This heat / cooling effect is called the Peltier effect (some French guy) and some people call these things peltiers etc.
They work, buy passing a relativly large current 3-20 amps, depending on wattage. to draw heat from one side to another basically. one side is -10 degrees c. The other is +80 degrees c. However, if you don't power them and instead create a temperature difference, i.e. stick ontop of a hot computer chip. You wil have set up a temperature gradient. So it will generate electricity. Typically you get around 4ma per 1 degree C. So nothing huge, unless they have refined them. So in this case, the bigger the delta T, the more power. I guess it could power a fan then! Seem's easily possilbe, but I wouldn't expect battery life to be much more than 30 mins at most extra. As 1 fan doesn't draw THAT much power!
Still a good idea though!
If anyone else has any questions, on how they work, images, tech drawing, or my product, i'm happy to answer them all!
BTW: Forgot to add, the generating electricity idea, from one of these, is called the "Seebeck Effect"
