one a corrupt bios. it asked for usb or floppy with the bios, I tried feeding it that with the correct bios, and now I only get a black screen; cmos resetting etc does nothing, seems dead.

The other one, I dont know. It still works, but I noticed a resistor burnt out and there is black stuff like it exploded all the way to a nearby chip (I think raid controller, but not sure). Funny thing, havent noticed anything not working yet (didnt test raid), but Im reluctant to put expensive cards in it.

Miners will always earn transaction fees, so it will never hit zero. 

Even with bitcoin, transaction fees might as well be zero atm. YACC (yet another crypto currency) will take forever to just reach current bitcoin status, becoming that much more popular than bitcoin today, so that miners could live off transaction fees seems utopian.

Quote
In Bitcoin, the 50BTC per block only lasts another year or so; then your earnings are cut in half.  It keeps decreasing in the future.  Will Bitcoin still be secure once we're past the initial currency distribution phase?

At least Bitcoin will be secure for several years to come, as secure as its value rather than its growth, and have a chance to grow as an economy, while being secure. If transactions dont pick up over the next 4 or 5 years to keep enough miners in business, well, it probably doesnt matter anyway. But unlike bitcoin,  I dont think your scheme would overcome the first few years while being even remotely secure, and that insecurity will have an impact on adoption. Catch 22.

You have some good idea's, but I dont think it would work

I like the new difficulty though. Just a shame I lost 2 motherboards in 2 days (!). Will take a bit before I can finally get to fire up all my GPU's.

While my "farm" is configurable using startup scripts, and monitoring is possible via ssh sessions it is "clunky" with just 5 rigs (30 GPUs). If I ever expanded I think management will just become more of a pain in the ass.  I have to think there is a better way.  I am thinking single webpage interface on a host that has current status of each rig, plus options to restart, and modify settings.  akak BAMT but based on debian lxde and using the vastly superior cgminer. 

Sounds like a plan. Now make it happen Smiley
FWIW, I was in fact already looking for a way to remote manage cgminer without needing SSH. I wanted to make a simple android  app to monitor and control my rigs. Web based might be good enough tho.

So therefore the profits of the miners, and therefore the hashrate, which could leave the network vulnerable.

Correct.  That's one reason that the inflation rate algorithm has to respond slowly and smoothly.  Gradual changes don't break the network - we've seen a 10x devaluation of Bitcoin over the last 4 months, greatly cutting into mining profits, but the difficulty is able to drop fast enough to compensate.

But your proposed system would amplify the problem many fold. If you'd have a long period of sustained devaluation, your algorithm would or should approach zero coins per blocks, essentially making all mining unprofitable. Thats very different as with bitcoin. With bitcoin the hashrate follows the exchange rate, it will never approach zero unless the price of the entire chain approaches zero. In your system the hashrate would follow the derivative (in the mathematical sense) of the exchange rate, and approach zero with just the smallest constant devaluation. Sounds very risky to me.

Moreover, although this is only a secondary effect, but with bitcoin you still get to mine for those 50BTC per 10 minute, and regardless of their value and profitability, Im sure some miners will speculate on future valuation gains. So you will see  people mining bitcoins even if its not profitable, as a form of speculation,  but if you cant even mine any decent amount of coins as in your proposed system, then pretty much no one would.

Quote

To prevent a 51% collusion attack, a third safety is possible: create a "decentral bank".  This would be a second mining system where people perform proofs-of-work solely to manage monetary policy, which means authenticating price quotes and the inflation rate.

I like that idea better. Although you would need an incentive for those  miners. One that doesnt create reevalution Smiley.

Quote
The fourth safety is the strongest: anyone can verify that the price quotes in the block chain are correct, and the inflation rate responds very slowly and smoothly.   If it becomes apparent that the system is being gamed, we'll have time to figure out why and how before coins start being generated excessively. We then release a new version that adjusts whatever is necessary to close the loophole.  In the worst case, we revert to 50BTC per block.

Hmmm..  not much of a solution IMHO. You're saying if you dont like the monetary policy, then fork, and hope the rest will follow. You've clearly given this some thought, you found nothing better ?
2486  Economy / Economics / Re: What would be the most effective way to stabilize BTC price? on: October 31, 2011, 11:34:15 AM
The target block rate wouldn't change.  Only the number of coins generated per block would change.

So therefore the profits of the miners, and therefore the hashrate, which could leave the network vulnerable.

Quote
Mining is a great technique for decentralized consensus.  My idea is to mine the exchange rate into the block chain.  Miners can use any source they want.  The rest of the network would evaluate the price quote.  A little tolerance would be allowed due to different data sources, but blocks with obviously wrong quotes would not be relayed, and the next miner would fork the chain from before the block with the lie.

Woha. Out of the box thinking there Smiley. Not sure this is a good idea though. Miners would have no incentive to set honest exchange rates, they want to maximize their ROI. They will collude to manipulate it and the result could be far worse than what we have now.

Have you flipped the overclock switch? Im not entirely sure, but if you havent, I think the card will throttle to stay within 375W, potentially rendering your overclock pointless.

Is there a way to tell cgminer to stop running after x minutes?

If it can't be done in cgminer is there a method via script in linux to tell cgminer to shutdown and then restart after x minutes.

The reason I ask is sometimes cgminer is unable to restart dead miner.  It happens rarely but with 12 GPU it does happen and when I fail to detect it hours can past and that is wasted time.  What I have found is that when a GPU "dies" stopping cgminer and restarting it from terminal fixes the problem 100% of time.

So if I could have cgminer run for 60 minutes and then quit I could setup a script that simply restarts cgminer everytime it quits which likely would give me nearly 100% uptime with little need for monitoring.

You could use a simple cron script to kill the process and restart it every hour.

Drastically reducing the block rate could leave the network vulnerable though.. I also dont quite see how you would put this in code, I mean, who will determine the exchange rate? But its an interesting idea nonetheless.
2490  Economy / Economics / Re: What would be the most effective way to stabilize BTC price? on: October 31, 2011, 08:23:38 AM

My proposed solution is to use dynamic inflation levels (by increasing coins generated in mining) to prevent excessive price growth against a currency basket until there's enough stored value to provide inherent stability.

Interesting idea. But how would you cope with deflation?
2491  Other / Politics & Society / Re: "Socialism, like the ancient ideas from which it springs..." on: October 31, 2011, 07:58:07 AM
I mean I have never lived in a Socialist state,

No one has, socialism in the original sense of the word has never been really tried (aside perhaps for some very short lived experiment in Spain in the 30s). Oh, sure lots of countries have called themselves socialist and still do, and we have (deliberately) called lots of countries socialist that were anything but; they were the exact opposite of what I call socialist (and what would now arguably be called libertarian socialism); they were and are oppressive dictactorships with government owned production rather than stateless direct democracies with worker owned production The word socialism has pretty much lost its meaning now.

  Options and/or futures trading has frequently done just that for other commodities. 

They have done the exact opposite, they jacked up prices and turned commodity markets in to casino's to the point where sellers and end users of those commodities no longer use those markets to hedge against price swings. More on that, and some startling figures here:

Seems a bit of a catch 22... prices won't stabilize much without trade occurring within BTC and doing so is incredibly risky for any businesses making purchases with fiat.

Correct,  except IMO prices wouldnt stabilize even if trade picked up considerably. All it would achieve is higher exchange rate followed by more bubbles and bursts as new speculators gamblers enter this booming market.

2494  Other / CPU/GPU Bitcoin mining hardware / Re: Too dangerous to draw more than 1200w on Corsair 1200 PSU? on: October 30, 2011, 04:47:31 PM

That's really good to know. Just to clarify the max is 1200 dc.

Yes, but the 1200W DC rating is the addition of loads on the 12v, 5v and 3.3v rails. You will basically only be drawing power from the 12v rails.  To be sure, check the maximum specced load on the 12v rails (in watt or ampere, its always written on the side).

Then again, for an el cheapo 350W PSU, this might make a big difference as up to half of that  "350W" might only be delivered on the 5v and 3.3v, but a decent 1200W is probably all about 12v anyway, Id be shocked if it was specced for less than 90 amp (1080W DC)

Quote
Would I be correct to assume that a good PSU would have a cutoff aswell as opposed to letting itself blow up.

As mentioned above, yes. It even works fine on my lowly antec 500W
2495  Economy / Economics / Re: What would be the most effective way to stabilize BTC price? on: October 30, 2011, 02:13:39 PM
IM not sure it would be so hard. The exchange has your identity (if you trade any non trivial amounts), and bitcoins are perfectly traceable. The issue with regulating bitcoins is usually identity, but trading on a (regulated) exchange eliminates that problem. I suspect it would actually be easier to administer than most other commodities.

Of course there would be pitfalls; trade could move quickly to unregulated markets, although Im unsure how much of an effect that would have on the regulated markets.

Anyway, I didnt mean to say regulating would solve the issue in reality, but its one of the few theoretical possibilities at least. A more widespread adoption of bitcoin IMO will not solve the problem, and might even make it worse in the short or medium term if its going through a phase of rapid growth.

Litecoin seems nice for CPU mining...
no premined coins is a ++
also, shorter time for confirmation of transactions Smiley

Indeed. I dont know why people are so hostile to alternative chains (closed source implementations aside, thats obvious something you should avoid).

I like litecoin. Particularly the fast confirmations is actually a huge benefit.  No one should be under any illusions of it overtaking bitcoin, but alternative chains are great testing grounds, and hey, if bitcoin can make it to the mainstream one day, then Im sure some alternatives can too. Its trivial to exchange one currency for the other.  If its true there can only be one currency, then it will be fiat currency. I dont think its true, but time will tell
2497  Other / CPU/GPU Bitcoin mining hardware / Re: Too dangerous to draw more than 1200w on Corsair 1200 PSU? on: October 30, 2011, 09:38:47 AM
Are you drawing 1220w at the wall? Keep in mind the ratings are for power delivered to the PC at 12v (and some at 5 and 3.3v). Power supplies are not 100% efficient, assuming 85% efficiency if you deliver the rated 1200W to the PC, it will by pulling  1411W at the wall without exceeding its specs.

Those voltage swings are something else though. If any appliance can handle input voltage swings, its probably a PSU, but its still not good I think.

And as an observation, at least in my rig (Ubuntu, I'm currently only as fast as cgminer was, but in cgminer I saw a LOT of pool not responding, caching results, pool back, submitting msgs).

Im seeing something similar, I think. Ive gone back to using cgminer because its easier to manage remotely without gui (set speeds, fans etc over ssh); I have slush configured as failback pool and I keep getting tiny amounts of BTC from slush. Im not logging, so Im not entirely sure whats happening, can someone make sense of this:



2499  Economy / Economics / Re: What would be the most effective way to stabilize BTC price? on: October 30, 2011, 08:51:40 AM
This is nothing new really; regulation on commodity exchange has pretty much always existed; well, up until it was deregulated (mostly under clinton). and now baby steps are being taken to again impose some limits:
http://www.cftc.gov/IndustryOversight/MarketSurveillance/SpeculativeLimits/index.htm
(thought the exemptions that lobbyists managed to get in will likely make it very ineffective).

If it can be done for oil and food, I dont see why theoretically it couldnt be done for bitcoins.
2500  Economy / Economics / Re: What would be the most effective way to stabilize BTC price? on: October 29, 2011, 10:52:55 PM

lol
I agree with the rest of your post but, as for regulation goes nope you are thinking in the wrong direction.
The reason for the huge price swings is the relative size of the speculative market

Regulation could limit speculation by imposing position limits.
