Didn't work, still reporting v1.1.... and this is where I am confused.

Download and save (e.g., in C:\Temp):
 - https://raw.github.com/joric/pywallet/master/pywallet.py

Then in the directory that you saved that script, run:
 C:\> cd C:\Temp
 C:\Temp> python .\pywallet.py --version
pywallet.py 1.2

You are saying you get v1.1?
2722  Bitcoin / Project Development / Re: ICBIT Derivatives Market (USD/BTC futures trading) - LIVE on: December 11, 2012, 01:04:26 PM
there is a probability that profits from the futures will be capped because there are customers with open positions who may not have enough money in their accounts at a given settlement price. We'll provide full disclosure of the situation.

I sense foreboding.  

So someone that closes a position today gets 100% of the gains but someone holding to expiration gets capped?  And there's no knowing by how much?
2723  Bitcoin / Technical Support / Re: How long does bootstrap.dat take to import? on: December 11, 2012, 12:52:45 PM
Are you saying good hardware will cut the launch time? (well, obviously)....I mean, I always thought the bottleneck was slow internet speed to download said blockchain...


-----------------------
Bitcoin.org client v0.7.x
Estimate for first-time use, syncing the blockchain.  (Estimates obtained via wild-assed guess)

Poor hardware using bootstrap.dat: 2 days 6 hours
Poor hardware with fast internet: 2 days 8 hours
Poor hardware with slow internet: 2 days 12 hours

Fast hardware using bootstrap.dat: 1 day 1 hour
Fast hardware with fast internet: 1 day 2 hours
Fast hardware with slow internet: 1 day 3 hours

-----------------------

Bitcoin.org client v0.8  (Not yet released, or even near release-candidate)
Estimate for first-time use, syncing the blockchain.  (Estimates obtained via wild-assed guess)

Poor hardware using bootstrap.dat: 3 hours
Poor hardware with fast internet: 4 hours (?(
Poor hardware with slow internet: 5 hours (?)

Fast hardware using bootstrap.dat: 1 hour
Fast hardware with fast internet: 3 hours (?)
Fast hardware with slow internet: 4 hours (?)


(With "poor hardware" I'm referring to slower, modern systems.  I'm not referring to your P4 or an atom-based netbook.)
2724  Other / CPU/GPU Bitcoin mining hardware / Re: FPGA hardware. Where to buy? on: December 11, 2012, 10:32:39 AM
Can anyone tell me where I can get my hands on some to mine with and learn how to program these for other crypt o currency's. I know jals are on way out but I would like to get my hands on theses and maybe re program to suite others too.

The time for purchasing an FPGA for mining is long past.  If you wanted to buy one anyway to program on, then here are some specs:

2725  Bitcoin / Technical Support / Re: How long does bootstrap.dat take to import? on: December 11, 2012, 10:30:16 AM
So, I hadn't updated my bitcoin blockchain in a long time and it was taking forever to download. Then I found out about the Bootstrap.dat method. I downloaded it and put it in the bitcoin folder in my application support directory. I had deleted the whole directory and moved my wallet.dat outside of the folder in an attempt to restart the whole thing. Anyway, when I started it up it said "importing bootstrap blockchain data" and it has said this for about an hour now. Is this normal for it to take this long?

Very little of the time in synching the blockchain is spent on downloading the blocks and most of the time is spent on CPU and I/O.   Because you have bootstrap.dat locally, what little time was spent downloading the data is cut but the rest remains.

It can take a day or more.

Version 0.8 isn't ready yet but it uses a completely different architecture and knocks that down to about an hour, on good hardware.

Why can't I go through trustcash and make a cash bank deposit?

TrustCash no longer is serving any Bitcoin merchants -- BitInstant, AurumXChange, etc.  They may have another solution at some point in the future, but for now there is no cash deposit method at a bank.

Quote
The cash deposits to banks have been suspended as weíve had a number of problems with our partner. Until these problems are resolved, we wonít be accepting the cash deposits at banks.

If you have a Chase branch nearby you might be interested in BitMe, which accepts cash deposited at Chase:

You might also try a Local Bitcoin trade:

There are some discussions here about buying Bitcoin in different countries. So, for all who have bank accounts in Thailand!

I also see that for those in Thailand but without a bank account can use a cash terminal to load an OKPay account.

You didn't mention what payment methods you can offer.

e.g., PayPal, Dwolla, etc.
2731  Other / Beginners & Help / Re: Turnaround time on: December 11, 2012, 09:01:26 AM
Its best to wait for at least one confirmation.

Especially because the transaction you received itself might not be confirmed.  This can cause a problem if you pay someone else and then you find out that the transaction to you was a double spend after you've already paid.

Or if you are sending the funds to something like SatoshiDICE -- you might think you won, but until the transaction confirms your payouts won't confirm either.
2732  Other / Beginners & Help / Re: Accepting BTC on my website on: December 11, 2012, 08:20:40 AM
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.

2736  Bitcoin / Mining speculation / Re: On the contrary, its actually good ASICs are coming when they are... on: December 11, 2012, 05:26:29 AM
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
2737  Bitcoin / Mining / Re: Enjoy the Last 24 Hours of Profitable GPU Mining on: December 11, 2012, 04:58:41 AM
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:

Why not buy an FPGA or pre-order an ASIC?

You probably would want to read this thread first then:

2739  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.
2740  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.]
