Anybody know of a good source for replacement fans for 5970's?
Got some that are starting to get noisy, seems like they may have a shorted pole or something .... feel quite 'coggy' when turning by hand and sometimes make a clattering on start-up.
Would be good to know if it was worth the cost.

Well they could use ".bit" domain address and be outside of any jurisdiction ... it can easily be arranged for a donation of the namecoins if they are needed for registration.

So if someone with a lot of bitcoin were to delete all those accounts, could new bitcoins be created, or would there be less that many bitcoins in the system forever?
... the second option. They can not really "delete those accounts" but more that they could delete the private keys that give them access to those accounts, for all intents and purposes those coins are locked out of circulation without the private keys.

Even if someone did dump a massive amount of coins into the market, it's just a chance to get cheap coins. The price would adjust but overall things would continue as is.
I'm not too worried of someone hurting the market by dumping all of their holdings (the market would shift (I'd buy a shit ton of btc at a low price) and we would recover). I actually think this may be the best possible thing for the future of btc. If the original holders used their btc to invest heavily in the community (dump their holdings in 24 months) then this would solve the problem. Until then, a market that has 20% of it's value in a underworld-crypto unknown, will pay a heavy price to insure (READ PREDICTABILITY), which could negatively effect an adoption of btc for anything of large value. In 18 months time, that'll be less than 12.5% of the economy and decreasing ... assuming that they don't spend any of it into "circulation". Edit: I think that was me who sent a hat-tip 0.01 to satoshi's genesis block address but I can't remember for sure if I actually did it ... thought it would be neat thing to point at in block chain ... there's my bitcoin sitting in the first ever address ... can't see that he will ever move it ... or will he? Edit2: Nup, wasn't me, weird someone had exactly the same idea and actually did it ...

As a side note, if you wish to attempt to duplicate the builds, you can try using the script at https://gist.github.com/961527. The Linux ones should end up with hash-identical binaries, but I've never tested the Win32 ones. They might work, but I'd bet there are several small differences (build timestamps and such). Please don't comment on the build system here, that is best left to another thread and/or direct questions on IRC (I'm BlueMatt). Got a link to a thread with Redhat derivative (Fedora, CentOS, RH) builds help. It's just one missing package after another. The file "build-unix.txt" should perhaps be renamed "build-ubuntu.txt" ... not sure what other unix that file helps on but it is next to useless for RH.

chodpaba; would you have an estimate for the average difficulty increase we are experiencing currently ... i.e. have done in recent past since Feb. and will expect to experience for next 2-3 months? I'm looking for a good 'r' value for my rig lifetime total BTC output formula. http://forum.bitcoin.org/index.php?topic=9561.0a/(1-r)

there will be 36 by this friday and more added the following week
36 on each shelf?
|
|

How many GPUs on each shelf (and/or rig)?
Pretty hard to estimate heat without knowing that.

This morning I was awoken by my alarm clock powered by electricity generated by the public power monopoly regulated by the US Department of Energy.
I then took a shower in the clean water provided by the municipal water utility. Then, I brushed my teeth with that water, filtered to standards set by the EPA and my state.
After that, I turned on the TV to one of the FCC regulated channels to see what the National Weather Service of the National Oceanographic and Atmospheric Administration determined the weather was going to be like using satellites designed, built, and launched by the National Aeronautics and Space Administration. I watched this while eating my breakfast of US Department of Agriculture inspected food and taking the drugs which have been determined as safe by the Food and Drug Administration.
At the appropriate time as regulated by the US Congress and kept accurate by the National Institute of Standards and Technology and the US Naval Observatory, I get into my National Highway Traffic Safety Administration approved automobile and set out to work on the roads built by the local, state, and federal Departments of Transportation, possibly stopping to purchase additional fuel of a quality level determined by the Environmental Protection Agency, using legal tender issued by the Federal Reserve Bank and printed by the Federal Bureau of Engraving and Printing. On the way out the door I deposit any mail I have to be sent out via the US Postal Service and drop the kids off at the public school.
I park my car on the street, paved and maintained by the Department of Transportation, and put quarters issued by the United States Mint into the parking meter.
Then, after spending another day not being maimed or killed at work thanks to the workplace regulations imposed by the Department of Labor and the Occupational Safety and Health Administration, I drive back to my house which has not burned down in my absence because of the state and local building codes and the fire marshal's inspection, and which has not been plundered of all its valuables thanks to the local police department.
I then log onto the Internet which was developed by the Defense Advanced Research Projects Administration and post on the Bitcoin forums about how the Federal Reserve Bank is going to destroy us all because the government can't do anything right.
.... and then you took a look at your sorry, dwindling bank account and social security that has been ass-raped by the banksters and their minions in gubmint and reached for the .44 in the drawer under your desk ... ... your freedom under government spiel is an illusion, you are a monetary slave, indebted by by blind adherence to a corrupted medium of exchange.

Ah, don't you mean I'll have to uninstall the repository OpenSLL package, download OpenSLL tar ball and rebuild OpenSSL with ECDSA and EC support and then I can build my own bitcoin binaries on Fedora?
Any dependencies to watch out for when putting my home-built OpenSLL into Fedora that you know of?
You don't have to uninstall any packages. Just install bitcoin-custom openssl into /usr/local/openssl or somesuch. and what is the best way to redirect the linker away from the system openssl install to the bitcoin-custom openssl install when building bitcoind ? Update the top of makefile.unix. It is standard *nix build instructions... you must edit cflags/ldflags/etc. Describing compiler and linker -I and -L is beyond the scope of this thread, though, I'm afraid. I didn't ask you to. Just trying to establish some kind of standard way for people who (god forbid) prefer to build bitcoin on RH derivative linux. It is the best chance for bitcoin to make it into those repositories and get wider adoption. Anybody have plans to publish a makefile for building bitcoin on RH derivatives?

As an aside let's do that same formula for the total installed capacity of today's network;
Current output, 7200 per day or approx. 100,800 BTC for current diff. period.
Assume average network increase of 30% for operating life of current installed capacity;
Total BTC mined by today's network over it's life = 436,800 BTC

Just realised there is simple formula for estimating the total amount of BTC a given size rig will output. We do need to make one assumption, estimate how large the average difficulty increase will be over the life of the rig. So with this we can use the same formula that gives the total amount of BTC will be mined; (Bernoulli's summation of infinite geometric series formula) http://forum.bitcoin.org/index.php?topic=7638.msg112479#msg112479a + ar + ar 2 + ar 3 + ... + ar k + ... = a/(1-r) Eg; say your rig is currently producing 10 BTC per day, then that is around 140 BTC for the current difficulty period. This is the initial rig output, a, a = 140 ; initial rig output of current difficulty period Now a difficulty increase of say 50% is going to decrease your output in the next difficulty period by a third or r = 1/1.5 = 2/3 ; 1/(difficulty multiplier) So assuming an average difficult increase of 50% for life of rig, a machine earning 140 BTC in current period can be expected to output a total of 140/(1-0.6666) = 420 BTC Let's try something a little more optimistic, say average difficulty increases of 30%; (r = 1/1.3) 140/(1-(1/1.3)) = 607 BTC So; a/(1-r) ; formula for total BTC over life of rig where a ; initial rig output during current difficulty period r ; inverse of average difficulty multiplier (empirical r = 1/1.3) Edit: chodpaba has done some pretty in-depth analysis of difficulty-price correlations so may have quite accurate number for average difficulty increase estimate. Edit2: found chodpaba's data and calculated average difficulty increase over last 25 periods (50 weeks) to be 30.3%, see below.

US banning bitcoin is probably already largely priced into the market value for BTC.
Expect a relief rally when it actually happens or ... the longer it doesn't happen that threat will be discounted, i.e. stronger underlying price action.
