It seems that Apple can use GPL v.2 licensed software on these devices while having the devices work as they want to, but not the same with GPL v.3 licensed software.
They can use it fine, they just like the loopholes in GPL2, namely tivoization and patents, which GPL3 closes.
Basically, they have to allow Joe Random with his iDevice to take their code, tweak it, compile it, and stick it on his device. They're not allowed to use measures (DRM, locked bootloader, unoverridable signature checking, etc.) to prevent him from doing that.
Also, any patents that cover the GPL3'd software must be licensed downstream. So if Joe Random takes your GPL3 code which is covered by a patent and uses it in his own GPL3 project, you cannot sue him for infringing on that patent, though you can still sue any other infringes that aren't using your code.
Well it's kinda impossible for new findings to push it forward. Any new findings will either be the same age or newer (and thus don't make the news) or they're older and push the date back.
"Mining doesn't just generate coins, it processes transactions, which makes the whole thing work."
So the processing power is actually put to use in the underlying system, and not just wasted?
Correct. The subsidy (then later, the transaction fees) received for generating a block is a reward for providing the processing power to operate the system. As I said, the subsidy that everyone current mines for is just there to bootstrap the system by gradually introducing the full quantity of bitcoins.
Generating a valid block and adding it to the block chain basically adds all the transactions in that block to a permanent record of every transaction that has ever occurred, like a massive accounting ledger. You can peer at this conveniently via the block explorer site (http://www.blockexplorer.com).
That app looks useful. I recently bought an archos 32 myself, mostly as a ebook reader and video player. Works quite nicely, though I think I would have bought the 43 if I had the money, due to the expansion ability and larger screen (the 32 is a bit tricky to use without a stylus thanks to my large fingers).
Even simpler, there's a GUI version of that miner, though I can't link to it as the forum is slashdotted.
Though an additional note, your GPU will need to support GPGPU processing. That means at least an 8-series nvidia card or equivalent ATI/AMD (not sure on exact model)
The public transaction list is "address A sent X BTC to address B". Addresses are not necessarily linked to any one actual person, as you can generate new addresses whenever you like and shuffle your bitcoins between them. Some people generate new addresses for each transaction, making it very difficult for an outside observer to figure out who actually sent money to who.
1. It operates via proof of work. Finding a valid block requires a lot of processing time and having found a block is proof that you did that processing. Mining doesn't just generate coins, it processes transactions, which makes the whole thing work. The rewards for finding blocks is currently just to bootstrap the system. Over time, the rate coins are created at will fall (the number of coins awarded per block (called a subsidy) found halves every 210,000 blocks, which should occur about every 4 years. It will happen for the first time about 2 years from now, at which point new blocks found will award 25 BTC, rather than the current 50. 4 years after that, they will award 12.5 BTC, and so on) and then eventually stop with just under 21 million coins in circulation, about 22 years from now. Leading up to and past that point, miners will be rewarded for mining primarily and then exclusively via transaction fees rather than subsidies. The first miner to find the next block will earn the transaction fees for all the transactions in that block as a reward for helping to operate the network, much the same as a credit card company charges a small fee for processing a transaction, though the person performing the transaction controls the fee and can offer a higher fee to get their transaction processed sooner.
The worth of bitcoin is established the same way as with any currency, by being accepted as a medium of trade.
2. It's a hashing process. Basically, it takes the previous block's hash, a hash of the recent transactions, the current time, the current difficulty, and a nonce value, and finds the hash value of it, then checks if it is less than the target value. if it is, you just found the next block in the chain, and are rewarded if you were the first one to find it, and if you weren't first, you just confirmed that result. if not, it increments the nonce and tries it again until it is less than the target value (this process of hash-increment-check happens hundreds of billions of times per second throughout the network), then the process repeats itself with the newly found block and another set of transactions. This whole process occurs, ideally, once every 10 minutes.
As for the second bit, short answer, yes, long answer, yes, but. The more processing power you have, the faster you can do the above process, and the better your chances of finding the next block before someone else does. But the system automatically adjusts for the total network processing power via the difficulty (which is derived from the target value. the lower the target, the higher the difficulty). It tries to maintain a rate of 2016 blocks every 2 weeks (which is 1 block per the previously mentioned 10 minutes). If a bunch of processing power is thrown into the network (like what happened the last time bitcoin got mentioned on/. earlier this month and as is probably happening now), at the next 2016 block mark, the target value will be reduced and the difficulty rises to maintain that rate. If a bunch of people leave (as they lose interest or whatever), the target will be raised and difficulty will fall.
AFAICT, most non-3G tablets also lack the GPS he desires.
Though he can hook a GPS in via bluetooth, but I'm not sure if that works the same way as a built in unit as far as software and compatibility is a likely issue.
All except remove it permanently show as updated for FF4.
remove it permanently is not updated yet and seems to cause a nasty error on start up, but after clicking through that, it seems to work fine afterwards.
We should voluntarily limit population growth and over time let numbers fall.
News flash for you : WE ARE.
Go look at North America and European birth rates. Compare to death rates. Notice the latter is larger than the former and has been since the 60s. The only thing that has kept population growth going is immigration, and even that isn't working in some place, like Germany (Also Japan and Russia, though the latter is more to do with a high death rate), which is having negative population growth.
Barring a massive spike in birth rates, world population growth will level off in about 40 years.
Also, by the way, some gays reject the compromise of "civil unions." They, at least, do want recognition.
AFAICT, that's because civil unions and the like don't work properly in the US due to screwy interpretations of the full faith and credit clause. Marriage is one of the few things where the clause actually functions as stated and a marriage in any given state is guaranteed to be recognized by any other state. Civil unions don't get that part, so your ability to travel/move is reduced.
AFAICT, the law requires that a computer be accessed without authorization AND that "personal data" (I cannot find what their legal definition of this is exactly) must be exposed as a result.
Unless said router also has NAS capabilities in use or the log files can be considered personal data, the law does not apply.
The credit card company has 0 risk in that regard. They simply yank the money back from the merchant and leave them without the money or the product. I used to work for a company that made POS systems and we had several customers driven out of business by that bullshit and the credit card company's disinterest in taking security and fraud seriously.

Sadly, it's not new. It's the same one that shipped with 3.0

It only cranks up the processor use when firefox is the active window and that tab is active. It hits about 75% of one core on my box.
If it's in the background, it ticks along at about 2% of same core.
There's an extension for that, but it can't use the usual ctrl+tab shortcut due to limitations.

You can change it back to a normal menu bar with 2 clicks. Same applies to the annoying tabs-on-top thing.
I initially hated the awesome bar, though I've rather grown to like it. I use it as a search function for my bookmarks.

1997, when SBC tried to buy AT&T.
Said merger was approved when they tried it again in 2005, which formed the company now known as at&t.
Your information is out of date. 1080p was added to the ATSC standard in the 2008 revision.
I think I may be operating with a different definition of college than US readers here.
My college also has automotive and electrical (electrician and electrical technologist) programs.
Yeah, teachers don't spend any time to plan classes, mark tests/assignments, keep up with their field, assist students outside of class time, etc.
Except any version of internet explorer (no, 7 and 8 do not support it) on XP. It only works on vista and 7.
Recent versions on vista or 7. No version of IE on XP supports it. Even if you update to IE 7 or 8, it's still not supported.
Make a will, it's that simple.
That's a problem for married couples as well. There has been cases where spouses and blood relatives have fought in court to make such decisions.
Aside from estate taxes which function differently for married couples.
And you miss the point that a non-married spouse would not even have standing to go to court over it.

My friends from Texas request that you stop blaming them for that. He's from Connecticut, not Texas.
the risk the transaction is fraudulent.
Hahahahaha.
