Not a new wallet, but a new bitcoin ID, or payment address within the same wallet, is recommended to keep track of payments from different buyers.

Yes.  CoinDL.com was created with this, for instance.

I do not want to use google authenticator, and I don't want to have to buy Mt. Gox's yubi key.  

I believe you program the Yubikey OTP with the secret from Mt. Gox, just like you would configure Google Authenticator.

I'ld like to see that calculation (or I'ld be happy to run the numbers myself.)

What is your cost of electricity per kWh?  What hardware (e.g., what GPUs specifically)?

10.5c/kwh  .. 3300mh @ 1120watts

You are producing 3.3 Ghash/s and only consuming 1,120W?  That's atypical, at best.


I mine w/ just GPU's

Not just any old GPUs, and not without a lot of tweaking to get those numbers, I suspect.

Well, congrats -- you get about another 8 BTC worth of profit for the the next month before this happens:

If the foundry keeps up 4 layers a week from now on, it means ASICMINEr should receive the chips just before Christmas, so we could theoretically (hopefully) have something online before the end of the year....hashing the first ASIC mined block ever

then following that:

(~2-3 weeks)
First 6TH/s online
(~2-3 weeks)
Second 6TH/s online
(~0-4 weeks)
50TH/s of chips out
(~2-3 weeks, ~2-5 weeks if location changes)
Part or all of the 50TH/s online

Double dipping could only occur when product exists, it does not require any manufacturer take 51%, simply that they bring online their excess stock, to make money off both sales and unsold stock.

Not every ASIC manufacturer is selling hardware to customers.  From another thread:

You probably would want to read this thread first then:

2728  Economy / Trading Discussion / Re: Square's new account-to-account transfer ("Gift Cards") on: December 11, 2012, 04:21:44 AM
followed by a security shitstorm.

All the concerns about having a Bitcoin private key QR code exposed are kind of the same concerns someone printing out a Square gift card would have.   

So let's say I receive a $100 Square gift card to a grocery that uses Square Register.  So I print it out and go to the store and charge $15.

Then the next time I visit I scan it and it says $0 balance remaining.    Who suffers the loss?

I would suspect that Square would tell me I'm out of luck.    There is a difference in that the grocery would be able to tell where and when the remaining amount was spent. 

But it likely won't take long for thieves to probe the system and figure out how to take advantage of these weaknesses.
2729  Bitcoin / Bitcoin Discussion / Re: How would you like to design a bitcoin banknote? on: December 11, 2012, 04:14:05 AM
You kind of can't, but fortunately it is so expensive to get your own hologram that few are going to do it frivolously and without putting their name on them. Anonymous holograms are cheap there is no point in making a custom no name design.


Well, looks like bitcoin is no longer the only pioneer here.

"You can send a Square gift card to anyone with an email address. No smartphone? They can print out a QR code."

That's Square's Jack Dorsey:
 - https://twitter.com/jack/status/277824833130209280

I haven't seen a printout from Square with one of these gift cards, I'ld be curious to see one though.  (e.g., what size is the QR code).

But this paper QR code as a bearer instrument works because it is familiar -- it works kind of like cash [Edit: as long as the underlying electronic transaction can occur.]

2. Because of that, trading participants will try to "arbitrage" this fact and will move the price quite close to that value before trading stops.

And that's exactly what's happening.

So the BUH3 (March 15, 2013) BTC/USD futures are in la-la land at $16 and change:

While BUZ2 (December 15, 2012) is now within 1% of the Mt. Gox last / spot market price with just a few more trading days remaining.

[Edit: The site was updated, this is resolved.]

can you E-mail admin@bitcoinvideopoker.com the URL to your account?

e-mail? Seriously?  

E-mail is a clear text transport method, and thus is not good for sending URLs which have the ability to claim and/or withdraw bitcoins.

What's your GPG key so that I can encrypt it first?
2733  Other / Beginners & Help / Re: Transaction change vanished on: December 11, 2012, 02:02:43 AM
Know how to do it?

There is no install.bat, it is a python script. 

So I'm assuming you are a Windows user then.

Windows doesn't come with Python installed, so you would need to install that in order to run the script.

 - http://www.python.org/ftp/python/2.7.2/python-2.7.2.msi


Then download pywallet  (right click and "Save Link As" or something like that):

 - https://raw.github.com/joric/pywallet/master/pywallet.py


Then to run the script from the command prompt it would be something like:
  C:\Temp>  python pywallet.py

Though if the python executable isn't in your path you would need to probably add it and re-open the command prompt so that it is in the path.  There is more info here:

Dumped all the backups of all the wallets looking for "1PyDNpaHGaAxazG13Xa7sESVeQbympLrHw", no luck. Last backup of wallet #2 (last before sending and loosing the BTC) has among other stuff the following worrisome contents:

Just to eliminate any remaining possibilities, have you tried extracting the keys for wallet #2 using pywallet, rather than with the bitcoin.org client?

For him or for Bitcoin?

From another thread:

It looks like finally the point is getting across that Bitcoin can be useful no matter what the exchange rate.

That would be describing it as having intrinsic demand then, wouldn't it?  Cheesy

It has final demand, regardless of whether it is accepted for tax payment.

Maybe he now sees the source of value, where bitcoins simply aren''t "worthless credits on your computer".

This is quite a bit different take on Bitcoin from him since less than 60 days ago:

The future of money: New paradigms for the checkout, banking & currency
by Joel Falconer

Quote
There’s another kind of player in this new game, too. It’s one that has been greeted with the most skepticism and yet has the most potential for complete and utter disruption – cryptocurrencies, like Bitcoin.
[...]
Bitcoin improves on the old model for currency in many ways. Maybe it’s the prototype for whatever improved implementation overtakes traditional currency in the future, or maybe Bitcoin will take that throne, but it seems likely that our current model will be replaced, whether today’s governments come to allow it, or we have to wait for them to fade out – or be thrown out – of existence.
[...]
"What these technologies will unleash will be profound. Money can move instantly, anywhere and without restriction. A digital payment can move between two people as they pass each other on the street, or between two people on opposite sides of the Earth – with no difference between the character of the two payments,” says Erik Voorhees, who is a Bitcoin entrepreneur who works at BitInstant.
“Money will move in this direction – toward these enabling technologies – because it tends to follow the path of least resistance. New rails have been built, and it’s just a matter of building the infrastructure around them and the trains will start switching, unavoidably.”
[...]
“The technologies recently built enable significant new powers – but we don’t know whether these new powers will be seized by individuals or by their governments,” says Voorhees.
His final word is cautious for an area with so much untapped potential. “More important than asking “what’s next” is asking, “who gets to give the answer?”

Then let's say the next day the chargeback happens.  

What do I care?

Unless you're traveling, these are probably businesses in your community that will receive a chargeback. Being small businesses, they may actually remember you perhaps as "the one who's using Square gift cards".

Of course if the merchant were to alert me to there having been a problem with the transaction I would no longer do trade with the person who bought the bitcoins from me and I might even try to contact that party to try to help resolve the payment issue, but I can't imagine any way that it would become my financial obligation.

But since these gift cards can only be paid for and sent using the Square Wallet mobile app (which requires location tracking and a credit card on file), Square has a much greater control for fraud-prevention than if the merchant were to accept credit card swiped at the point-of-sale.  (Caveat on that though -- the mobile location tracking is easily spoofed, from my understanding, if you know what you are doing).

The point is, this is like being able to print and trade gift cards to paper with no tracking.

This capability has never existed before.

I guess it helps to have a former U.S. Treasury Secretary on your board -- you get to push the boundaries a little further without fear.
