Considering it's a new feature, there aren't going to be prewriten classes for it. The description says "Execute command when a wallet transaction changes (%s in cmd is replaced by TxID)". So I would imagine you set the command to a .php/.pl/.py/.sh script that fetches the full transaction info and updates your database. |

Bitcoind 0.8.2 has a -walletnotify argument, whenever a balance affecting transaction triggers, it sends the tx hash to an external script.
keep in mind it only triggers when a transaction affects the wallet. this will not list other user's transactions. only transactions related to addresses you own will trigger. |

Just wondering, why is your local time nowhere near any time zone in the US?
maybe because time posted =/= time picture taken |
|
|
|
it's in 0.8.2 Command-line options
--------------------
* -walletnotify will call a command on receiving transactions that affect the wallet. |

Off-chain transactions offer unlimited tps. Off-chain transactions aren't Bitcoin. Reason being... oh wait there is none. |

Are you really so cheap that you can't afford a 13 cent (0.001 BTC) transaction fee? 0.001 BTC is enough for most transactions to get into the next block.
Why some people insist on taking things to a personal level is beyond me. Who said it has anything to do with "me"? Otherwise why should I be surprised? see: "Responding to Tone" https://en.wikipedia.org/wiki/File:Graham%27s_Hierarchy_of_Disagreement1.svg Also, your assumption that 25 BTC subsidy is to provide free transactions is false. The 25 subsidy is exactly that: something to bootstrap the miners when there aren't enough transactions. There are plenty of transactions now and the subsidy has been halved already. Miners are under no obligation to include any transaction for free. Users should get used to the idea of paying (a fraction of a dollar) for fast confirmations. Even if you think a level 5 rebuttal is OK, I believe my tone was pretty reserved, not like that I complain or something. That doesn't change the fact your response revolves around my tone. Also, "level 5 rebuttal" is a really rosy way of looking at it. To put it in perspective, it's the third lowest tier, and only above ad hominem and name calling. And I didn't say the 25 BTCs reward is to provide free transactions, I was just surprised that miners still "care that much" about transaction fees when the 25BTCs reward is worthing a lot already.
Their reward got cut in half. You really anyone would be ok with their revenue halved? |

People have been calling for an end to moore's law for decades and been wrong. Besides, the only important parts of moore's law here is hard drive capacity and internet bandwidth, not CPUs here. These are not going to slow down their exponential growth any time in the next decades. Hard drive capacity in particular seems likely to have radical breakthroughs that smash the pace of moore's law.
Only problem: moore's law doesn't apply to bandwidth capacity. Case in point: I'm still stuck with my ADSL 1 internet. My other option is VDSL or DOCIS 3.0 but they are only offered by incumbents and they have a cap of 80 GB/month. Don't be ridiculous. Moore's law applies to bandwidth just fine. In fact it seems to be speeding up. The law does not fail just because when fiber is rolled out, it is not installed in your particular house. http://www.cabletechtalk.com/broadband-internet/broadband/broadband-speed-and-moores-law-a-response-to-robb-topolski/1980: 300 baud 1990: 14.4k 2000: 384k dsl 2013: 1000mb fiber Now we have exponentially growing bandwidth capacity that WE CAN'T USE. nice! Tell me, how many locales in the americas can you get 1 Gb/s fiber? |

Hmmm, yes, maybe it's a good idea to set up a pool which not just distribute shares to miners, but also give them the voting power when it comes to transaction policy? Otherwise I may want to relay transactions for free, but I couldn't even produce any effect without investing hundreds of thousands on equipments first.
that is being worked on: https://bitcointalk.org/index.php?topic=221164.0 |

3. Flip fan around so that it is blowing down
Wait, so the fan was originally pulling air through the heatsink? BFL engineering excellence right there.  |

We should only expand block size when there's a legitimate bottleneck. Satoshidice and other "on the chain" services does not count. Neither do small value transactions that can be settled by off the chain transaction providers. If you take away all of those, we have plenty of room to grow.

Come to think of it, there's no real reason why your hardware wallet even needs to communicate with the network. You're protecting your private keys, so all it has to do is be able to sign transactions securely. Communication with the network can be left to the merchant or any other third party.

It would be interesting if a 1btc penny (bitcent?) auction was added where each bid was exactly 0.01btc (or other small amount), and each bid reset the 3 block countdown. The last confirmed bid made when the blockrun runs out wins. That way someone couldn't just bid 1btc and ruin it. I could see that going for awhile if there are a few interested parties.
#1 problem with that: blockchain spam. even worse than satoshidice #2: Why would any rational person bid on it? Sure, you have a chance of winning, but so does everyone else. It's against a rational actor's interest to enter the auction at early, because the game is all about attrition. Once a person makes his 100th bid, he's making a net loss, and everyone knows that. By entering early, he's putting himself at a disadvantage. |

dipsy: stop putting up bitcoin for bitcoin auctions. It's retarded because anyone can sabotage the game. All they have to do is put in a bid for 1 BTC and they'll ruin it for everyone.

How long does it usually take a transaction with no fees to confirm?
anywhere from instantly to never. In your case, with unconfirmed inputs and low priority, I'm guessing 1 day after your inputs confirm. |

wait, why would you ask higher than what you paid for?
I'm not. ASKING
$275 @ MtGox Weighted Avg My mistake, did not see the updated price. However, your price is still above market price. Please see my previous post: Yeah, I checked ebay and I knew something was up. Completed listings for galaxy tab 2 10.1: https://i.minus.com/id1toFFg481Cs.jpgAs you can see, you can get a brand new galaxy tab for less than $200. A quick search shows completed transactions for used going for under $100. If you place it on ebay, you'll probably get $150, minus $15 (conservative 10% fee). This doesn;t even include the tax I paid.
And how does that matter at all? The market pays for what the tablet's worth. What you paid for it is irrelevant. |

You're asking $600 for a used phone that retails for $650. A quick ebay search reveals new iPhone 5 sold for under $300. You might want to lower your expectations.

Yes, I am just surprised that miners(most of them pools) still care that much about transaction fees, to the extent that no-fee transactions would sometimes take forever to be included into a block, I thought the 25 BTCs reward is already enough for them to take minimal care about how many free transactions they have to include, especially given that we are still nowhere near the size limit.

All my recent no fee transactions are included quickly (within 10 blocks). You probably played satoshidice too often, or your wallet is full of dust inputs. |

Sipa has an up-to date branch for coincontrol. I have built it using gitian in my build VM. (VMWare Ubuntu guest, Windows 7 x64 host). My Windows build 1: bitcoin-0.8.2-sipa-coincontrol-win32.zip (SHA b7bc93cdaacbe24b42bff6714d59a9fcc49e85dc) linux users: do it yourself. you probably know how to do it and you don't have to trust me. mac users: sipa's build script doesn't build mac (I think). sucks to be you, I guess.  summary of my build instructions: git clone -b coincontrol git://github.com/sipa/bitcoin.git
git tag -a v0.8.2-sipa-coincontrol -m 'sipa coincontrol'
./bitcoin-build.sh v0.8.2-sipa-coincontrol |

It was at 12% at one point and a large pool (I forget which one) had heard about it, but now it is at 0%. Any ideas?
most likely explanation: network propagation statistic is really buggy (like with all blockchain.info "features"). I recently sent a 0-fee transaction with NFTF patch and it achieved 95%+ network propagation. A few minutes later, it magically dropped to only 1 node. |
