... My claim is that both high inflation and high deflation are bad, and that both low inflation and low deflation are tolerable.

You have to use a clear definition of deflation/inflation before discussing it. Bitcoin itself cannot be deflationary since no Bitcoins are destroyed. Bitcoins can be 'lost' or otherwise stuck without access but that does not change the core of the protocol.

If Bitcoin is thus not deflationary, or at least nothing extreme (lets say below 1%), the deflation you seem to have in mind is decreasing prices. Well, that's the economy and not Bitcoin. Changing equilibrium is just what free markets are about. New balance will be found until market preferences change again.

The wacky thing is how intensely inflationary Bitcoin actually is in terms of supply.

In the first year, Bitcoin experiences a whopping 600% inflation. We won't hit 1% amortized inflation until another 11-12 years from today. At present we're still above 10% inflation.

You will have one hell of a time keeping them cool in a normal case, especially in summer.

I would offer them for sale with a tech bench: http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=103_467&products_id=33104

Or with a HAF922: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119197
and replacing all the 120mm fans and the side 200mm fan with high static pressure R4s: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103061 (search online, you can find them for ~$5 each)
I know from experience that you can fit 6x 120mm fans in a HAF922 and that is cools really well (1x bottom, 2x side, 1x rear, 2x top). For the fans on the top/bottom you should get fluid bearing or ball bearing fans too, as cheap sleeve bearing fans like R4s tend to fail quickly when placed on their sides: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233035

Yes, it's like $30-50 worth of fans, but it will ensure decent airflow over the GPUs so that you don't have customers calling you and complaining in the summer that their rig is dead because of heat. My personal experience is that MSI cards have the best aftermarket cooling too, so I wouldn't buy anything but those. They are still available if you search a lot for them.

Edit: I would also recommend the following PSU instead of the bronze one you chose http://www.newegg.com/Product/Product.aspx?Item=N82E16817182084
The reason being that this PSU will have >90% efficiency at the est. 450-550w or so you'll be pulling from the PC and also the 7 year warranty and also the price.

Maybe the merkle root of the genesis block is the same as the hash of its only transaction?

Yes, it is. The merkle root is the root hash of the hash tree for the transactions. In the case of a block with only a coinbase transaction (the only required one) it's simply the hash of the coinbase transaction.

If you're trying to get the merkle root hash for the genesis block, just hash the coinbase tx twice or SHA256(SHA256(coinbase transaction))

That's really weird; try

Code:

--auto-gpu --gpu-engine 950-1050,950-1180 --temp-cutoff 80,80 --temp-overheat 70,70 --temp-target 50,50 --auto-fan --gpu-fan 50-95,50-95

In the second GPU

Hello Tacotime, on Windows 8 I have this problem of trying to save my current settings, I had exact same thing with guiminer for Bitcoin.

What happens is whenever I press save button nothing happens afterwards so none of my settings save. When I tried doing other way by right clicking on guiminer icon in tray and pressing close in the windows pop-up it asks if I want to save my settings I press yes and nothing happens, the program doesn't close either.

Try running as administrator, it may be a security feature

You may also need to edit permissions on the C:\Users folder as this person did for Program Files http://social.technet.microsoft.com/Forums/en-US/w8itprogeneral/thread/7b3ada32-181d-4c55-9259-ee44f5f83b82/

Discussion of it is forever banned on overclock.net. Not exactly sure of the logic behind it.

I'm uploading my reaper kernel for my 7950s because I'm wondering if some of the troubles people are having are related to poor compiling. I noticed that if I recompile my kernel now I no longer get 1.8 MH/s but get more like 1.6 and I have no idea why that is.

Tacotime,

Last time I had installed Windows 7 x64 and done -all- of the Windows updates before trying to run the miners. This time, I've installed Windows 7 x86 and haven't done any Windows Updates yet (this is the only part of the process that has differed from the previous time).

I'm currently doing the Windows updates and will attempt the miners again. If this doesn't fix the problem, then I think the problem might be x86 vs. x64 in Windows?

Like I said, in x64 I could run 21712 or 24000 no problem. I have 16GB of RAM and the cards only total up to 15GB (3GB per card), so it shouldn't be a problem there. I'll check back after the updates are done and let you know what happens. If it doesn't fix it, I'm going back to x64 and will report back again after that. Gonna track down the problem one way or another!!

-Moose

Oh. That's the problem, x86 only supports 3.5 GBs of RAM.

How come I was getting double reward for a while today?

So I can tell you with confidence that you mined very few blocks (e.g. 10 blocks) during that time and you're not millonaire, or you are part of the Satoshi group, period.

Do I get to be Satoshi too? I was off by only a few days... https://i.imgur.com/w57rtbs.png

I know first-hand that there were several different people who mined before January 2010. It's kind of funny that history I've lived through is being questioned...

Get used to it, there always seem to be wild rumours about Litecoin flying on the alt chains forum. I have solo'd blocks from immediately after release of that chain too, and people are always saying any manner of crazy artforz or coblee premine accusations.

It should be noted that mirror1 links to version .03 and mirror2 links to v .02.

I forgot to change the version by accident, the build is of ver 0.03 right now though. I think I wrote the update at like 2AM after being awake for a day and a half.

Anyway, a lot of people are getting this "-5" error lately and I've got no idea what's causing it exactly.

Hey tacotime!

Are you going to upgrade GUIMiner to include cgminer 2.11.4 anytime soon? (:

Soon, week of 4/22/13. In the meantime you can just delete the contents of the cgminer folder and replace it with the contents of the agminer 2.11.4 zip file if you want to use it.
Busy with some other extremely important things related to work for me

The stratum proxy was working fine until I rebooted my computer. Now it throws errors. I have restarted it twice and nothing has changed. This is what I am getting.

Also in GUIminer-scrypt alpha it is pointed to coinotron.com:3334, do I need to point it somewhere else like a local host to get it to use the stratum proxy?

Miners should be pointed at localhost port 8332
Proxy should be pointed at the pool, coinotron.com port 3334

Quote from: cptmooseinc on April 14, 2013, 12:31:39 AM

Not possible through GUIMiner currently.

It should be through extra flags, just add

Code:

-o stratum+tcp://yourpool.com:3333 -u username -p password

Whenever cgminer sees arguments for a second pool it just appends them to the backup pool list

One thing to note about the blocks from genesis to 30,000 or so is that
a) They, for the most part, all appear to have different coinbase transactions.
b) They are also almost completely unspent.

I think the likeliest scenario is that hundreds of people downloaded and ran the client then, got a bunch of blocks that were at the time useless because they were valueless, then deleted their clients. Recall that in May 2010, bitcoins were only trading for 0.0025 USD each. It's my personal guess that these coins are just lost to the chain forever.

Started mining Litecoin large October last year (bunch of 7950s). Was making about $100-200 a month. Was pretty cool with that. Paid off the rigs in 4 or so months. Hoarded all the Litecoins I earned for shits and giggles, I think they were worth between $0.05-0.08 but the price was stable so I didn't care.

Fast forward to March. Litecoin went up to $4, dumped most of them, made 2000%+ profit on investment. Bought another 3 rigs with some of proceeds. Am mining and hoarding again. If the price goes down, good. More LTC for me when the difficulty falls.

The arguments above are more or less the same ones people were making when I was mining for Litecoins at 0.06 USD each. I ignored them. I made a lot of money. Unless some major problem comes up with the chain, I'm going to continue ignoring them.

Okay, time to get back to work here.

Hey, trying to stay out of here for a bit, but someone brought these cards to my attention and I thought you guys might want to know about them if you're still building rigs

They are AMD 7970 reference boards and thus have really solid voltage regulation and RAM, VRMs are all really well cooled. As such they should all also have voltage control. Once these go out of stock they will likely not be replaced, so grab them while they're still around.

edit: voltage control confirmed with sapphire trixx http://www.overclock.net/t/1378557/sapphire-100352-4l-and-21196-00-20ghd-7950-the-final-holy-grail-of-hd7950s

We already have a decentralized exchange: SilkRoad.

What we need is one not on the deepweb that lets users exchanges normal goods/currency/services for cryptocurrency that is decentralized and has a rating system which is not easily hijackable. Ripple is not the answer; ripple is modestly decentralized system (see Ripple node list) that is dependent on a centralized means of transfer via US banking intermediaries. There's no reason why we just can't overnight gold or cash to one another.
