wow thanks, I was aware of those buttons but I wasn't entirely sure what they did, like with a lot of stuff programmers do not just with Bitcoins you never get explanations as clear as this.
Ask for a How to in the dev forum, and I'm SURE at least one of the ones you will get will be clear

Any mod please sticky this thread. That's exactly the kind of info that should be posted more frequently into the newbie area instead of the announcement for the next possible opportunity to burn money through gambling (Ignore my sig, I just take their money for advertising. I'm not using the site, since I am not into gambling, if you are into gambling that's fine and this site should satisfy you).
Ask for How to's in the dev forum, some of them will be glad to make one

From a quick glance I don't see where the problem can be
I'll work on it in around 3-4 hours and will report info here
3943  Bitcoin / Development & Technical Discussion / Re: Pywallet: manage your wallets/addresses/keys/tx's on: June 03, 2013, 02:04:08 PM
Ok... And this?
Code:
pywallet.py --info --importhex --importprivkey 0000000000000000000000000000000000000000000000000000000000000001 --otherversion 18


Could you please give me a dummy private key so that I can look at that?

Wouldn be the first 8 digits of a private key enough to check Balance??
No

What are you using? WUI or CLI?

What does this give you?

3947  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANN] Quantumcoin on: June 03, 2013, 11:11:47 AM
To answer a few questions:

  * Why Quantum? Why not? It just liked the word.

  * What's new with QTC? First the block value is addicted to the difficulty. Higher difficulty results in higher block value. Second the target timespan and the retarget interval is addicted to the overall network hashrate.

  * Why no Windows binaries? I think a source release is sufficient. You can build windows binaries with the included Makefiles. Just install the MinGW Toolchain (including UPnP). I have to do that for every alternative coin because they usually don't ship Linux binaries.

  * Why are there premined blocks? Just to have a higher starting difficulty without mining a genesis block with a high difficulty. Sure, it's not the number of the blocks determining the difficulty, but the difficulty just adapts slowly over time.
You could have put a 0 (or ~0) reward until block 1000 or so
Otherwise I like this coin
3948  Bitcoin / Development & Technical Discussion / Re: Solution for "The Filter Issue" and "dark" data stored in blockchain on: June 03, 2013, 10:22:26 AM
We all know bitcoin can be used as a means to store "dark" data in the block chain.

Most of the ideas I tumbled across are based on recipient's address filtering.

This concepts seems to me nothing but absurd, since whatever filter is implemented, there will always be a way to fool such filtering process, and store data.

Here, I propose a method that:
 - Eliminates arbitrary data-storage in the blockchain
 - Eliminates lost money due to mistyped addresses (if ever anyone types an address)

The solution is as simple as this, both payer and receiver must sign the transfer. This could've brought up the double-spending issue again,
but here is how to solve it.

Bob wants to pay Alice

Bob sends transfer to Alice's address

Such transfer is confirmed in the blockchain

After such confirmation, Alice must sign such transfer within the next N block confirmations (e.g by re-transfering the money to another (her's) address, or by creating a new type of packet "transfer confirm")

if after N blocks no-one confirmed the receipt of the money, bob is allowed to spend it again. Such transaction can then be removed.

How does this attenuate the "dark" data storage?
The person that wants to store data, sending to a fake address (which contains the given data) needs to have the private key of that address - > which is pretty complicated.
Nevertheless, it is still possible (and will always be) to store data using a vanity address...

How does this solve "mistyped" addresses?
The receiver cannot sign the receipt, and as such the money goes back to the sender


What do you think about this proposal?


Edit: made some makeup on text
So one would need to know he has been paid to actually receive money? He loses everything otherwise?
Even banks are more practical than that

Hello,
Do i need the whole public key to check balance or are a few digits of the key enough?
Thx alot
Full public key or hash160

Yes, they do something but probably don't really know what are they really doing. That needs brain, not zillions of fixes to JS libraries.


Trollboy, down, down trollboy. Allow me engage you in a little thought experiment:

Let's assume that 20% of coders at Microsoft don't know what they're doing (probably a LOW estimate).
Now let's assume that 40% of coders building open source tools don't know what they're doing (TWICE the above percentage).
A Microsoft product and an analogous open source product both have roughly the same severity of bugs in them.
The bug in the open source project is:

* found faster (source is available, debugging is simple)
* fixed faster (far more coders submitting patches, no release gating)
* fixes are tested faster (source available, patch/release fast if needed)

Javascript libraries are hardly exemplary of open source software (this served your straw man argument well), many are not GPL
or are commercial, many of them suck, etc. The LAMPPP stack is still far superior to Microsoft in security, reliability, performance,
and TCO - last I checked, this trollwar ended around 2008 with resounding defeat for the Microsoft fanboys.

"The war is over, you can come out of your Windows 2008 Server troll-cave"


Are you... feeding a troll?
Nice post though, I'll keep a link to it somewhere just in case

Ugh again I have to ask this - What can LTC/BTC do that another coin can't? It goes both ways.  I know one thing though, a new coin can make YOU filthy stinking rich, whereas btc has already made others rich.
1 point for you

  • email+url: look at regex
regex? what is that exactly? i'm afraid i don't know much about it. i'm self taught so my knowledge is *extremely limited*

  • you don't fclose

the script works fine without it.. is it really necessary?

  • I don't see any echo so how can you display error or accept?

i call the echo down below in the form:

Code:
<div id="result">
<? if(!empty($error)) echo '<div class="error"><img src="fail.png" /> '.$error.'</div>'; ?> 
<? if(!empty($accept)) echo '<div class="accept"> <img src="ok.png" />'.$accept.'</div>'; ?>
</div>


Regex are something specifically designed to validate patterns. Warning: that's pretty annoying.
Sure it works without fclose but you're using RAM for nothing and you're locking the file for every other process until the PHP script ends. Oh, and PHP gurus will kill you.
Looks ok, so I'd put many echo's in your big 'if' to see what happens: check all your variables at many times.
3958  Bitcoin / Development & Technical Discussion / Re: Unspent outputs on: June 03, 2013, 08:31:39 AM
I didn't study a lot about what happen but I don't see how two different transactions with same hash can be spent, because of the uniqueness of txids as gmaxwell pointed out

This raises a question: is this uniqueness part of the bitcoin protocol or only part of the current clients?
Because allowing same txid for different transactions could be possible in theory. By starting the output indexes at the last output index of the previous tx for example (not sure if clear)


Btw thanks you guys for the number of unspent outputs and the rpc command

--otheraddress doesn't seem to work when dumping a Bytecoin wallet.
What is "doesn't work"? What would you want? What do you get? What is written in the console?
