I'd buy PDU(s) that can be controlled from the network.  If one of your rigs goes down, becomes unresponsive,
you should setup a monitor server and power cycle a faulty rig.

Insanely expensive.  Remember PDU are rated on maxed switched capacity and even 5 KW PDU are $500+.
10562  Bitcoin / Bitcoin Discussion / API to get daily price for Bitcoin. on: March 30, 2012, 04:04:25 PM
Anyone know of any API to get Mt.Gox daily price information for Bitcoin?

There is:
http://bitcoincharts.com/t/trades.csv?symbol=mtgoxUSD&start=1315906316

but it returns every trade.

I just need daily price.  Would prefer volume weighted average price but opening price, closing price, simple avg price, just about anything on a daily basis would work

Something like this but for BTC:USD

I want something other than dollars.

Maybe people don't want what you got?

I mean honestly I don't hoard, I routinely trade or sell 80%+ of the coins I have mined over the years.  Still I don't really care about an old piece of junk computer or a stick of gum.

Just yesterday I bought a yubikey off a noob.  No dollars involved.
I have bought gold coins from vendors, I routinely snap up useful computing hardware in the marketplace.

Some girls who never heard of Bitcoin before this week got more coins than you have simply by sharing naughty pics.

Maybe what you are offering is just worthless?

Hoarding doesn't reduce fungibility.  If anything it simply drives price up (less coins in effective supply) but the nominal price of Bitcoin is irrelevant.

I see. So stats based on the public address won't be accurate as her balance is split by several instawallet-controlled addresses. That was the whole premise, wasn't it? I mean, the script posted before looks at her transactions based on blockchain.info while that's not their actual balance, though it may roughly be.

Trying to determine CURRENT balance based on blockchain won't work for the reasons given.  The address instawallet (or any exchange) gives you is simply the deposit address.  So theft or no theft there is no way to know how much or when funds were transfered or current balance.

Still any script that looks for tx TO the deposit address is looking at how much was GIVEN not the current BALANCE.  The amount donated/given will be exactly accurate however no public stat can tell you someone's balance (unless funds never move).

But my account balance wouldn't show a dollar being sent elsewhere from my account. My account doesn't show individual dollars as entities, they only show balances. Equivalently in Bitcoin, there is no such thing as individual bitcoins with their own entity, there's just transactions. So what is instawallet doing there? Still confused.

Blockchain =/= view of YOUR (or HER) account.

If you deposit funds at say Instawallet or MtGox or xyz bitcoin bank there will be tx that occur as the entity moves coins around, combines them, and handles withdrawals that don't correspond to YOUR indvidual account.

Nothing weird about what is going on @ Instawallet.  If you deposit funds @ Mt.Gox the same thing happens.

No online entity keeps all the funds in the deposit address.  They combine funds to be able to take some of that OFFLINE so only a small portion is available to hackers.

Her losing coins and the Instawallet tx in block chain have nothing to do with each other.

In related news theives are using Gold to get dollars.  They think Gold is a joke.

So unless "hoarders" start saying what they want in terms of goods and services, we're going elsewhere. Litecoins, fartcoins, whatever it takes

Why do you need the "hoarders" coins and what they hell does that have to do with fungibility.
10568  Other / Beginners & Help / Re: Block Chain Summary or Ledger or Balance on: March 30, 2012, 12:52:43 PM
What you can do, is forget the used outputs.
Only problem with that is you don't have the complete blocks anymore for new clients that want to download the blockchain.

Well you can't forget outputs because they are what is used in new txs.  You don't send an amount you transfer outputs thus to be able to verify future outputs you need to have a record of all outputs with value not just balances of addresses (which is completely useless).

So while you could prune off all dead end tx chains you need to save every output which has been unspent.  Combining that into a summary wouldn't save significantly more space that simply providing the pruned blocks.

Lastly your "space savings" of 1GB -> 30MB is not even in the right magnitude.  It makes people think you are just storing address balances.  There have been analysis done which estimate the space/bandwidth savings of to be more like a 75% reduction not a 97% reduction.
10569  Bitcoin / Bitcoin Discussion / Re: What if someone bought up all the existing bitcoins? on: March 30, 2012, 12:40:48 PM
It can be done, but it would potentially cost tens of billions of dollars for one person to buy up that much coins, as the last few thousand/hundred coins will be insanely expensive.

I respectfully disagree. If there's only a few thousand bitcoins left in circulation, and one entity controls the rest, then the community will flee (probably to another blockchain), the infrastructure will shut down (why run nodes if you have no coins), exchanges will close (as trade grinds to a halt).
And in that situation, is there much value left in a bitcoin? Scarcity isn't the only thing that determines price or value. The last dodo wasn't worth "insanely much" when it was killed.

The entire global economy could run on a handful of Bitcoins.

21M is simply an arbitrary value.  If 20M were lost Bitcoin would work just as well on 1M coins in circulation.  If 20.9M were lost it would also work equally well with 100K coins in circulation.  Conversely if Satoshi had made the block reward 50,000 instead of 50 then Bitcoin would also work equally well with 21B coins in circulation.

Bitcoin is divisible to the 1E-8.  So 100K coins is  10,000,000,000,000 discrete units, but even that is just set by consensus.  Bitcoin could allow smallest divsions if a majority of hashing power agrees.  At sat 1E-12 that makes 100K coins in circulation = monetary base of  100,000,000,000,000,000 discrete units (that's more than the # of pennies in global money supply).



10570  Bitcoin / Pools / Re: [1437 GH/s] Slush's Pool (mining.bitcoin.cz); supporting p2sh! on: March 30, 2012, 12:34:42 PM
The solution hopefully would be using a hop proof algorithm.  Score based pools can still be hopped, tweaking the score isn't going to change that.  It may for a while and then hoppers will adapt.

Given PPLNS, SMPSS, PPS, and DGM are all well tested and hop proof prop and score based pools are an anachronism.
10571  Bitcoin / Mining support / Re: 100 % cpu bug on Slush's pool on: March 30, 2012, 02:55:12 AM
cgminer.  (yes that is a period)
10572  Bitcoin / Pools / Re: [340GH/s] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: March 29, 2012, 11:23:56 PM
so i followed the guide for windows and got my local machine to mine and run  p2pool, but how would i point my other machine running bamt to it? i tried using the username:password i setup in the rpc conf and pointed it to 127.0.0.1:9332, yes the ports open, but it did nothing. thanks in advance

127.0.0.1 is a special address for localhost

127.0.0.1 on your other machine is look back at itself not looking at the machine running p2pool.

you just need to replace 127.0.0.1 with the local IP address of the machine running p2pool.  likely it is 192.168.x.x
10573  Bitcoin / Bitcoin Discussion / Re: Offline Paper Wallet Creator - Raspberry Pi? on: March 29, 2012, 09:38:04 PM
It might have even more use if it could print paper wallets on demand like tickets.  I could see using a $50 printer like the Brother QL 700, for instance, where the first ticket / printout is the private key and QR code, followed by a second printout that has the public key and its QR code.   (Though I now wonder if thermal paper printouts will fade and become too obscure to scan, as time passes?)

Be careful

Thermal resin (uses paper + ribbon) will last "forever".  The resin will likely last longer than the paper.
Thermal (uses only chemically treated paper with no ribbon) will be unreadable in a matter of months (days if exposed to higher temps).

Some printers can do both, some can only do one or the other.

Quote
So together, for under $100 of hardware, an individual would have an offline bitcoin paper wallet generator.
Or at least an excuse to order a Raspberry Pi.  Smiley

Pretty cool idea.

Sorry but there is a huge problem with this. Its so easy to copy their photos and photoshop in another adress which will happen.

I dont know how they will be able to prove that they are the owner of the adresses.

reddit is self moderated.  I am not saying they will embrace this but if they do it would be pretty easy to ban and delete scammers.

Wouldn't the simplest solution be to drop GUI Miner and use a real one?
10576  Bitcoin / Bitcoin Discussion / Re: payment with a message on: March 29, 2012, 08:35:02 PM
So I often claim? I've never claimed that before. And I believe I said it works for private individuals, but not businesses. When and if satoshi decides to crash the market for his big payday, you will certainly be able to link many of his public keys.

Will you? 

Or is it someone who bought coins off Satoshi and hundreds of other early adopters over the course of years? 
Or was it actually Satoshi who moved coins around making it look like someone else acquired coins off him and other early adopters for years?
10577  Bitcoin / Bitcoin Discussion / Re: payment with a message on: March 29, 2012, 08:29:08 PM
derp, you're right, but there is still essentially nothing gained in anonymity, so why bother

So you often claim.

Please tell me how many coins are controlled by Satoshi.

I will get you started I know he had at least at one time access to the private key linked to this address:
http://blockchain.info/address/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

10578  Bitcoin / Bitcoin Discussion / Re: payment with a message on: March 29, 2012, 08:23:28 PM
forget about donations, how about running a high volume business? A business simply cannot use a different address for each transaction via common sense. If they are ever going to pay for anything, hundreds or thousands of addresses would be combined into a single transaction costing them lots of money in tx fees. Obscurity through many addresses may work for private individuals, but it will not work on a large scale and does not offer any real additional anonymity.

Paying with 1000 inputs from one address is going to have the same size and face the same fees as it would if you paid using 1000 inputs from 1000 addresses.

Bitcoin works on inputs and outputs.  Ultimately no matter how many addresses are used same # of inputs = same size.

Little to no revenue would be lost as I have built into my model a two card failure system. I have two cards that I tested that are sitting on a shelf as spare parts. I would replace the broken card with that one, then order a replacement with either overnight shipping or second day shipping as I have free two day shipping with Newegg and Amazon.

Wait so instead of losing 2 weeks of revenue when a card does die (if/when that happens) you will lose 50 weeks of revenue the hot spares could be generating all the weeks that they aren't running?

Well whatever works for you.
