But you DO blow on the first date, right? You know Vlad is kinda of guy and doesn't like that.
Of course
It makes them spit the load faster

Load = money, of course


Like the guy who gave you 1 NUG.  AVOID!  Lol
I asked 1 NUG, he sent me 1 NUG. Where's the problem?

Man, I don't wanna imagine that, what if she's a he?  Then I'll be all confused in the head.
You don't need me for this, bro

Obviously 1. != 2. so I think we should use another word for describing 2.
I've never seen anybody using another word, did you?

A spend with Bitcoin is a "confirmed" transaction.   Most services do not credit a transaction as confirmed until there are six block that have confirmed the transaction. 
That's the problem, sometimes people use double-spend even for unconfirmed transactions. That's exactly what I'm talking about here: I'm asking what word to use to describe the situation where there are two unconfirmed transactions using the same input.

For example, this guy made a transaction that doesn't get accepted in the blockchain and need to pay a specific address with the same input before tomorrow.
The new tx he will made is what I'd like to name.


I'm not talking about these (which deserve their names) but rather about things like this: https://bitcointalk.org/index.php?topic=232979.0 or https://bitcointalk.org/index.php?topic=231309.0 (ie rebroadcasting the same tx with more fees for example, nothing malicious)

But the term double spending is never used (as far as I've seen) when referring to "replace by fee" capability:
 - http://bitcointalk.org/index.php?topic=199947.0
Indeed, I wasn't thinking about this feature, I just meant broadcasting a transaction that uses the same input than another unconfirmed transaction


PS: I'm very aware that my english is far from perfect and that this makes such technical talks difficult. Sorry for that!

Not sure how this could happen, but never trust your clipboard. It could lead to bad things in Bitcoin Grin
2304  Bitcoin / Bitcoin Technical Support / Re: Double-spending vs Double-spending on: August 20, 2013, 05:42:31 PM
1. single digital token
2.transactions that use the same input
The word you are looking for is "confused".

Double-spending is exactly how you would describe a successful reuse of a unique single input in two different outputs on two valid transactions.

While this has not "happened" in history if you consider the blockchain the official "version" of history, it actually happened during the great 0.8 database incident.

I'm not talking about these (which deserve their names) but rather about things like this: https://bitcointalk.org/index.php?topic=232979.0 or https://bitcointalk.org/index.php?topic=231309.0 (ie rebroadcasting the same tx with more fees for example, nothing malicious)

2 should be "Double-spending attemptGrin
That's also not the kind of double-spending I had in mind but it's a good precision to add for this kind!

1.
According to Wikipedia:
Quote
Double-spending is a failure mode of digital cash schemes, when it is possible to spend a single digital token twice

2.
Bitcoin people sometimes use "double-spending" to talk about the fact of broadcasting two (or more) transactions that use the same input with only one being accepted in the blockchain

Obviously 1. != 2. so I think we should use another word for describing 2.
I've never seen anybody using another word, did you?

What dependencies are you talking about?
Could you post the tx you'd like to broadcast?

What is the value range for k?

k must be between 1 and p where:

p = FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE FFFFFC2F

    = 2^256 − 2^32 − 2^9 − 2^8 − 2^7 − 2^6 − 2^4 − 1


This largest value is different from the one mentioned in the wiki (https://en.bitcoin.it/wiki/Private_key), which is  0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141. The exact number is not very important, but just out of curiosity, which is the right one?
The latter
What you wrote is n and is the upper limit
p is just the prims number you use when doing EC operations

By the way its not really an upper limit: n+1 is a pretty valid private key, it's just that it's equal to 1 (as n+1 mod n == 1 mod n)

2313  Bitcoin / Bitcoin Technical Support / Re: Is it safe to re-use a paper wallet BTC address after spending it all? on: August 19, 2013, 10:24:04 AM
When you don't reuse addresses, your bitcoins are protected by ECDSA (Elliptic Curve Digital Signature Algorithm), SHA-256 and RIPEMD-160. On a first transaction you publish your public key, so only ECDSA lefts. However, I believe that it is still pretty secure.
Congratulations for posting the only technical post.
ECDSA is indeed enough. If an EC becomes broken, Bitcoin won't be the first target.

Can someone send me 1 NUG? The sooner the better!
Thanks a lot holy brothers

I'm trying to recover a devcoin wallet that was overwritten during a moment of carelessness. I'm real new to Python but have got pywallet running in the CMD line in Windows (64 bit Windows 7) and am at the options menu.

I'm getting a couple errors - 'ecdsa' package is not installed, and 'A mandatory option is missing'. Also am not getting http://localhost:8989/ to display, am seeing 'neterror connection failure' in one of my security addon pop ups in my browser window.

ecdsa not being installed is not an issue
The mandatory option missing means you didn't tell pywallet what to do
If you want the web interface, you must do
Code:
python pywallet.py --web
If you want to recover wallets (impossible with the web interface), you must do
Code:
python pywallet.py --recover ...
The exact syntax is here: https://bitcointalk.org/index.php?topic=34028.msg2794856#msg2794856


Just wanted to confirm that it will work recovering overwritten dvc keys? And have figured to set path to destination folder, but unsure on how to configure command (with path), and how to get web interface working. Any direction appreciated, even if I cant recover, it's always good to learn something new.
I confirm it will recover them, if they still are physically present on your disk
As I wrote above, the syntax is
Code:
python pywallet.py --recover --recov_device c: --recov_size 30Gio --recov_outputdir c:\recoveredwalletsfolder
This will create a huge wallet.dat in c:\recoveredwalletsfolder
It will contain all the keys it could find on your disk, whatever the altcoin you were using them with
