You can patch your own bitcoin-qt client, or you can use one pre-compiled (and signed) by other trustworthy members. Or you can use Armory as that has coin control.

laser "engravers" are usually for drawing line art. They have really bad shading capability. Usually, if you want something shaded, you would use masking tape + sandblast.

You do realize that you can't ship human waste with most delivery companies, right? You'll have an even harder time getting them through customs.

Specially because everybody's pushing for the emergence of a "free market" for tx fee. As I understand it, it would mean I can decide of a minimum fee if I want to, it is not that esoteric as a whishes.
But whatever is the reason for people to use it or not, if it exists as a parameter it should at least be documented for advanced users and developers. My view is that, if as a user of bitcoind I interact with it at the level of raw transactions, I would need a full documentation and I should be able to understand the reasoning of the core devs about what makes sense as a usage or not.


There should never be undocumented "features". How terribly unprofessional. If they don't want people using it, they should not put it in.

see:
It was left out because the developers did not want users to tinker with it. Having an inconsistent fee policy across nodes has a devastating effect on the network. If each node has its own relay policy, it would be difficult for the client to decide what fee to use. This will result in transactions not being propagated.

Type this 8 digits of your PUBLIC KEY from your sig here:
www.blockchain.info
WHAT DO YOU GET?

19QkqAza
how fucking dense are you? I already explained how typing partial addresses "worked" in blockchain.info.
2248  Bitcoin / Development & Technical Discussion / Re: List of all bitcoin.conf parameters on: June 03, 2013, 05:21:33 PM
From your explanation I understand that the parameter is for filtering transactions that are relayed?
What I thought was that this parameter is to specify a minimum tx fee to include, even if the transaction is smaller than 1KB. Currently the rules implemented in the bitcoin-qt client sends some transactions without any fees if they meet a certain number of criteria. There is no way to enforce that a fee is always used?
that's a different setting. paytxfee is for how much fee per kb.

also, release notes for 0.8.2:
Quote
Fee Policy changes

The default fee for low-priority transactions is lowered from 0.0005 BTC
(for each 1,000 bytes in the transaction; an average transaction is
about 500 bytes) to 0.0001 BTC.

Payments (transaction outputs) of 0.543 times the minimum relay fee
(0.00005430 BTC) are now considered 'non-standard', because storing them
costs the network more than they are worth and spending them will usually
cost their owner more in transaction fees than they are worth.

Non-standard transactions are not relayed across the network, are not included
in blocks by most miners, and will not show up in your wallet until they are
included in a block.

The default fee policy can be overridden using the -mintxfee and -minrelaytxfee
command-line options
, but note that we intend to replace the hard-coded fees
with code that automatically calculates and suggests appropriate fees in the
0.9 release and note that if you set a fee policy significantly different from
the rest of the network your transactions may never confirm.

If i copy the first 8 digits of the public adress in your sig i get this:
https://blockchain.info/address/19QkqAza7BHFTuoz9N8UQkryP4E9jHo4N3

Still NO it doesnt work?
It works, but it's by no means a definitive match. what you're doing is "firstbits", in which blockchain.info tries to find the first address with the matching prefix is used.

first 8 digits of private key would not work at all, due to how public key cryptography works.

another iPhone 4S is up for grabs. (at&t)
I'll bid 1.5 shipped to Canada if:

  • It's "like new" (no visible damage except for oil/fingerprints)
  • It has 4.x.x or 5.x.x firmware
  • willing to use escrow
2252  Bitcoin / Mining support / Re: Overclocking Water-cooled GPU's on: June 03, 2013, 03:21:24 PM
Keep in mind you're supposed to underclock memory unless you're mining scrypt (which I don't recommend). As for voltage, the general rule is that you increase voltage until it's stable OR it's too hot (over 80 C). Since every chip is different, it's impossible to say how much voltage is needed.
2253  Alternate cryptocurrencies / Altcoin Discussion / Re: BTC vs LTC Mining on: June 03, 2013, 03:18:20 PM
Yes. I agree with Eastwind.
I'm mining LTC because I'm speculating on LTC value. At the moment if I were completely rational I should mine BTC and exchange it for LTC.

BUT to do that you need to exchange, you have fees to exchange and fees to withdraw if you don't want to leave your money to the exchange platform.

And also you get a delay from exchanging. Today it's more profitable to mine BTC but maybe in 3 days it will be back to LTC.

So i guess if you believe in LTC and don't want to worry too much about exchanging, you shall keep mining ltc
But LTC has been consistently less profitable than BTC. Right now it's sitting at 88% profitability. Unless you pay an insane exchange fee of 10%, it will be more profitable for you to mine BTC and exchange for LTC. You will simply get more LTC per hour mined.
2254  Bitcoin / Mining support / Re: Hash rate drops when screen power its turned off - GPU ATI on: June 03, 2013, 03:16:19 PM
I'm guessing your graphics driver switches to low power mode the instant the screen turns off.

Most likely yes, is there a way to avoid it? Any register that its possible to change to avoid that or its more bios/hardware config. ?
check power settings in control panel and disable any power savings mode related to graphics. also, if you have some sort of AMD configuration utility installed, check for power saving mode there too.
2255  Bitcoin / Development & Technical Discussion / Re: Does your Bitcoin-Qt v0.8.2 takes 5 mins to verifying block database integrity? on: June 03, 2013, 03:10:14 PM
No. It takes 1 minute max.

However, if you find it annoying, you can do this dangerous tweak:
"checklevel=1" in bitcoin.conf
2256  Bitcoin / Development & Technical Discussion / Re: List of all bitcoin.conf parameters on: June 03, 2013, 03:08:30 PM
Out of the documented list? Why? Other parameter as well?
It was left out because the developers did not want users to tinker with it. Having an inconsistent fee policy across nodes has a devastating effect on the network. If each node has its own relay policy, it would be difficult for the client to decide what fee to use. This will result in transactions not being propagated.

http://www.alloscomp.com/bitcoin/old_calculator.php

if you look at the source, you have:

  var rate = your rate
  var target = 0x00000000ffff0000000000000000000000000000000000000000000000000000 / your difficulty
  var p = target*rate*1000/Math.pow(2,256);
  var result = (-Math.log(1-your confidence interval in decimal)/p)

where result is in seconds
