I've heard people stating that XFX are fine, they just run hotter than others.  So, make sure you're cooling them well.  Otherwise, they should be fine.

Welcome to volatile markets.  That means they go up AND down, sharply.

If you can't handle the losses, don't play.

No problem.  Write your own client.

As to who pays the fee.  The originator of a transaction pays it.  But as the previous poster mentioned, it could also be deducted from the amount of the transaction, hence the receiver would always pay it.  But keep in mind, if you receive coins you'd pay it.  So if I'm paying you to do work for me, they would get deducted from your pay.

At that point you'll argue the employer should pay them.

So you're really arguing that YOU shouldnt pay them.   

I answered the question, he didn't ask for examples.

I'd be happy to write one, need:
     Command to check temp of each card, sample output
     Command to run miner for each card
     Output of 'ps ax' while miners running

Thank you for correction, my bad.

Your pool may have temp banned you for some reason

Difficulty changes are every two weeks.  So 48 hours would affect nothing. 

Yes.

It's a transaction fee, and you're the one conducting the transaction.  It could happen to you just moving money between your own accounts.

Why a transaction fee?  Because without it, eventually no one would mine, and if there are no miners then no transactions will be confirmed.  If transactions aren't confirmed, then there is no Bitcoin commerce.  

Think of it as a tax to keep everything running.

Strong encryption is not illegal in the US.  However, there are laws preventing us from exporting it to certain other countries.  These are the same laws used to govern arms dealing.

PM me, I can do it.

Your subject says OS 10.6.7.  Your crash dump says 10.5.6.  Upgrade your OS.  Double-check the OS under the Apple -> About this Mac.

The large mining pools are being DDoSed.  Therefore their hashrates drop as a percentage of the total hash pool.
Also, as miners cannot connect to pools, they go solo, so the "Other" portion rises significantly as a percentage.

When the pools are back online, the miners will move back, and then you can post about how you're concerned Deepbit is 51% of the pool.

Mining is required to verify transactions. 

If there are no miners, then there will not be any confirmed transactions, because no new blocks will be added to the block chain.  If that happens, Bitcoin is dead.

However, miners currently receive TWO incentives for mining:
1)  They earn 50 BTC for every block found (which halves every 210,000 blocks on the blockchain)
2)  They earn transaction fees for all of the transactions confirmed by the block they found.

In theory, as miners exit, the difficulty will be reduced, so it'll be easier, not harder, to find blocks.  When #1 is no longer attractive, the theory is that there will be so many transactions confirmed by a block that miners will keep mining just for the transaction fees.

You need to be considering the case of people who have substantial amounts of wealth in Bitcoins.  Say I have $100,000 worth of Bitcoins.  What you are suggesting is that I make a $100,000 wager that I can keep my computer free of zero-day viruses, FOR LIFE.  I am not willing to make that bet.  It is, after all, a Windows machine.

Making backup wallets and storing them for years makes a lot of sense.  Paper is far more durable than any electronic medium.  What medium would you suggest that is going to last 100 years?  Floppy?

Any single media?  None.  However, I have electronic documents that I've kept around for 25+ years.  How?  I keep the media they are stored on current.  When I upgrade my laptop, the documents get moved to a new one.  That laptop is then backed up in 3 different places.  So, I have four copies in different locations.

You're comparing a medium that has been around for thousands of years, to a medium that has been around for less than 100.  You have no idea which will prove better in the long run.

If you wish to backup your life savings in Bitcoins to a paper document, knock yourself out.  I'll be backing mine up electronically.

My argument wasn't which was better as a backup medium (go back to the first page), it was an argument against paper as a way of safeguarding bitcoins against errors in coding and/or viruses.  I'm not saying paper won't work.  I'm saying if you're putting it on paper to avoid problems in the electronic environment, you're kidding yourself, because in order to use the paper, you have to make it electronic again, and at that point, you have all of the detriments of it being electronic again.

I, for one, hope everyone gives up on mining.  More for me and the difficulty will plummet.

This was covered, in depth, in an article here:  http://glennfrancismurray.com/cost-defective-mining-with-gpu-clusters-amazo

If you wish to lose money doing it, it's a great way to spend your time.

Good luck finding 58XX cards at all.  Unless you want the XFX versions (which run quite a bit hotter) you're out of luck, as all of the Sapphire cards are out of stock everywhere.

We need the entire command line that generates that error.

However, I'm guessing you have a character that the shell is swallowing, then you're getting unmatched quotes.

One piece missing I didn't see...

For the first 210,000 blocks "discovered", the protocol allows the finder to pay themselves 50 BTC.  That transaction is then confirmed by subsequent block finds.

The reward for finding blocks is halved for every 210,000 blocks after.

The miner doesn't "find" those 50 BTC, they are allowed to be paid to the miner as a reward (plus the transaction fees of the transactions confirmed by that block).
