 Anyone have a rough idea of what their costs were to build that?   ( and what the total dollar cost of shares was? )

All the chips are out of stock anyway -- each order has a 10 week lead time.

But question was related to device that probobaly will take months to generate at least one block Smiley
So there is no "time for last n blocks" in this case

I didn't realize the thread was from so long ago either.
1645  Bitcoin / Bitcoin Technical Support / Re: Average block generation time on: June 26, 2013, 09:33:42 PM
Average block time = time for last n blocks / n
1646  Other / Beginners & Help / Re: What is Palio diet and how effective is it for weight loss? on: June 26, 2013, 09:32:41 PM
I have my own diet:

1)  I only eat 2/3 of what I put on the plate.
2)  Go to the gym and hire a trainer.  Work out 3-4 hours a week with a trainer or in a class.

You'll definitely lose weight.

I'm beginning to think the lightning box picture is just a mac mini.  But just in case I've sent the 100BTC upgrade fee.
1648  Economy / Web Wallets / Re: Help: How do I sign a message using my blockchain.info address on: June 26, 2013, 09:21:04 PM
what do I do with the key? Send it as a pm?

Noooo never do that
You sign a message with the key.  Whatever wallet you use must have a "sign a message with this key" option.

So you use your private key to sign a message.  Only the person with the private key can sign the message.  Anyone with the public key (bitcoin address) can validate the message.  It's how bitcoin works -- only the private key holder can sign a message to spend bitcoins.  Anyone with the bitcoin address can verify the bitcoins were spent.

No, many of us are ordering spares.

Looks like bitpay is working again.  I got my order in but messed up the transaction fee, hope it goes through without problems.

Edit:  Got 1 confirmation almost immediately -- K16 here we come!
1651  Bitcoin / Hardware / Re: [Ann] US based Avalon ASIC chips and assembly: 2,779 remaining on: June 26, 2013, 03:19:06 PM
any coupon available  Smiley

Found one on fatwallet Smiley

But I'm getting failed to create bitpay invoice at the end Sad

read the fucking post. he says he wants it to be provably fair. A black box RNG is not.
"release the hash ala satoshi dice before hand" IS provably fair. You are the ingnorant one here, not him Tongue

No. It's not.

I could create a raffle where I know what the result will be ahead of time.  I could tell the result to my friends so that we would win every round.  I could then hash the pre-determined result and "release the hash".  After play was over, I could release the result to prove by way of the hash that the result wasn't modified after the beginning of the game.  Unfortunately, this would not be a "fair" game.

Releasing the hash is only one part of a provably fair game.  It prevents the game operator from changing the result after the game begins, but it does not prevent the game operator from knowing the result before the beginning of the game and taking advantage of that result.  This is why Satoshi Dice uses a hashed secret combined with the transactionID.  Satoshi Dice cannot know the transactionID before the transaction is submittted, and the player cannot know the secret before the day is over.

I assumed you would combine your secret hash with the entrant's transaction ID as well to determine the winner -- what else would you do?

You can PM after making one post.
1654  Bitcoin / Bitcoin Discussion / Re: Vanity Keygen on: June 25, 2013, 05:18:02 PM
Type in a whole private key (or as many letters as it will let you) and scale by network hash rate then scale by # of letters you weren't able to enter.  It's like 10^30 years to find one.

The idea is that it's more profitable to mine bitcoins than to try to brute force a private key.
1655  Other / Meta / Re: Bounty to nuke Alt-Coin board on: June 25, 2013, 05:14:45 PM
Just ignore the whole section.
How do i do this, especially since I like to use the "Show unread posts since last visit." quite frequently ?

Profile -> Ignore Boards Preference
Then just click all the ones you don't like.  I clicked all the foreign language boards.
1656  Alternate cryptocurrencies / Altcoin Discussion / Re: If you had 40GH to mine alt coins... How would you mine them? on: June 25, 2013, 05:00:36 PM
If you could mine at 40GH/sec for scrypt doesn't that translate to 40TH/sec for bitcoin?  I'd do bitcion at that rate.
1657  Other / Meta / Re: Bounty to nuke Alt-Coin board on: June 25, 2013, 04:59:17 PM
Just ignore the whole section.
1658  Bitcoin / Development & Technical Discussion / Re: Using Bitcoin Block Hashes For Random Numbers on: June 25, 2013, 03:15:55 PM
It's better to just take a random number if you want a random number.  You can release the hash ala satoshi dice before hand.

pkarc's last post was over two weeks ago and he hasn't logged in in a week.  Hopefully for you guys he's just on vacation with no internet access...

I bet one of the ICs on the board is the most expensive -- you could look up their prices pretty quickly.
