You have to use a separate miner, like m0mchil's poclbm.py.  Your 4850 should generate around 1 BTC per day, based on the current difficulty level.  If you do solo mining, you will get a block on average once every 50 days.  If you join a mining pool, you'll get a little less than that, but in a steady stream rather than a whole block (50 BTC) at once.  You can think of mining receipts as a reward for supporting and protecting the network.

Welcome to the community.  I rounded up your Bitcoin balance with a small donation.  There's a whole section of the forum just on Mining, so you'll have to plod through that to get a feel of what is involved in successful mining.  Basically, you need an ATI 5XXX or 6XXX graphics card and a machine you don't mind leaving on 24/7.

As to what you can market for Bitcoins, it would be just about anything you currently possess or can offer as a service.  In addition to the Marketplace section, check BiddingPond.com and bitcoin-otc.com.

If someone wanted to attack the network, they could send a large number of very small transactions since the cost to do so is small.  There is code in the client to guard against this.

Get a hardware keylogger and put it in series with the keyboard cable.  Then have your parents install something innocuous like a math study program.  After they are done, retrieve the administrator password from the keylogger.

Great interview!  Kudos to both spenvo and mndrix.

I'm glad to hear you got this working.  I got lucky as the fglrx version that was automatically installed from the repository was 10.9.  In m0mchil's miner thread, there is plenty of discussion that SDK 2.1 is the least problematic, so I started with that as well.

There are some really nice discussions taking place there.  Many people defdending Bitcoin quite well against the skeptics. 

I was going to suggest dropping the SDK back to 2.1, but he said in the OP that he already tried that.  All of my miners run fglrx 10.9 and SDK 2.1 and I have no problems.

The beauty of having universal fabricators at home is that anything you wish to possess can be represented as a code or data file.  This means it can be purchased and delivered over the internet, with no physical interaction.  This in turn means that it can be done anonymously, if the item is paid for with a peer-to-peer cryptocurrency like Bitcoin.  The bottom line is that 90% of the economy can move to the untaxable gray market.  States will be unable to control the economy or extort revenue from it.

For the past several years, I've been thinking about a near-term project along the same lines.  Imagine a desktop chemical synthesis unit that could perform a large number of different chemical reactions under software control.  You could supply this machine with simple, readily-available substances like household solvents and amino acids from milk, and it could synthesize a wide variety of recreational and prescription drugs.  For example, DMT and psilocybin (active ingredient of magic mushrooms) can be synthesized from tryptophan, found in milk.  This is not wild science fiction as the technology already exists to do this.  You can make polydimethylsiloxane microfluidic devices at home that can become components (reaction vessels, separation chambers, etc.) in such a synthesis unit.  To make it easy on people, some enterprising individual could manufacture and sell the subsystems which could be assembled into a finished unit (I'm imagining that a complete synthesis unit would be outlawed at some point).

I think we're long overdue for dividing Marketplace into separate sub-forums.  Even before the Chinese onslaught, it was becoming difficult to find things of interest.  The suggestions by stonetz seem like a reasonable starting point.  This would force anyone posting there to think a bit about the nature of what it is they want to buy or sell.

I actually did have the same exact problem, and it was solved by setting the DISPLAY environment variable properly.  I don't know what to say.  Does it do the same thing when mining against bitcoind?

The only other thing I can think of trying is deleting the /etc/X11/xorg.conf file and running "aticonfig --initial --adapter=all" again.  I've found that, for some reason, aticonfig doesn't always create a proper xorg.conf file if one exists already.

There's definitely a paucity of bids, at any price, on Mt. Gox right now. 

Make sure you really have the DISPLAY=:0 environment variable set.  Enter it on the command line before starting poclbm.py.

I think partyp's latest design is the best in this thread so far.  I'm ambivalent about the blue border.  genjix, I understand your sentiment, but I think the majority of the world's population associate a polished look with quality, rightly or wrongly.

If port 8333 is not forwarded, you cannot accept inbound connections.  However, you can still forward transactions received from one of the 8 connected nodes to the other 7.  So it still helps.

I believe there are a few other things that miners take into consideration.  Even once the initial equipment has been paid for, there is an ongoing maintenance cost.  Most miners are buying consumer-grade power supplies, fans, etc.  These will begin to fail after a few months of 24/7 overclocking duty.  Then there is the noise if you don't have your equipment located in a server room or closet/cellar somewhere.  There is also the problem of cashing out or exchanging your BTC for local currency.  I think a lot of people got into mining without thinking everything through, and some are dropping out due to the expense/hassle/inconvenience.  We will lose a few more when summer comes to the northern hemisphere.  It is already 27C outdoors here.

The link is dead.

I have seven clients which run 24/7, five of which are standalone mining machines.  Non-mining machines still strengthen the network by improving connectivity.

How are you connecting it?  DVI output directly to monitor or through a VGA adapter?  If the latter, try using the VGA adapter that came with the ASUS instead.
