The 'amount' column in the 'transactions' view isn't resizable, and doesn't fit in a value I recently sent.
xxx.xxxxxxxx BTC is ok, but -xxx.xxxxxxxx BTC doesn't fit, and I see xxx.xxxxx... instead (dots replacing the last 3 digits of the amount)
Three figure sums probably aren't all that uncommon to be sending, and it looks pretty ugly when the value doesn't fit in the box.

We're back online.
The order matching won't start happening until 9pm server time, to give users a chance to cancel any outstanding orders.
The price hasn't moved significantly while the exchange was down, but it seems only polite to give people a chance to cancel orders that they may not have intended to leave on the exchange.

What is the technical difficulty?
It's a filesystem corruption issue. We will have to restore from backup. It appears that this was a hardware failure. The bitcoin wallet wasn't compromised. |

jonathan, are you a time traveller from the future? You seem to be able to quote intersango messages days before they are written. i googled the message you wrote when you first wrote it, and it wasn't found anywhere... except in the future.
Next time you're in the future, could you grab me a screenshot of the bitcoin price chart please?
Thanks.

I had bitcoin-qt crash with a "Segmentation fault" error when I tried to open the 'options' dialog.
Running this command seems to have stopped the crashes: sudo apt-get remove qt-at-spi
Package qt-at-spi is installed by default when you install Ubuntu 11.10. It looks like this is a known bug in ubuntu's qt-at-spi package. You might want to include a note in the instructions about this. I had tried testing the Qt bitcoin client when it was first merged to the master branch but gave up due to these crashes. If I had known then that uninstalling qt-at-spi would fix them, I wouldn't have given up on the Qt client. |

I built bitcoin-qt v0.5.0rc1 in Ubuntu 11.10 with the following packages installed and had the following problems. ||/ Name Version Description

- doc/readme-qt.rst says that 'libdb4.8++-dev' is required, but it doesn't exist in the current version of ubuntu (oneiric). Only one version exists, which is what I installed. This debian bug talks about the issue.

- In the 'Send coins' tab, hovering over the address book icon pops up a tooltip saying "Choose adress [...]. "Adress" is missing a 'd'.
- In the same tab, clicking the address book icon opens a new window which has an 'ok' button but no 'cancel' button.
- bitcoin-qt is very noisy on standard output. Starting and just clicking through the 6 tabs along the top generates more than 3000 lines of text in the terminal that ran it. Could these messages go to the debug.log file if they're needed? Here's how it starts (piped through 'uniq -c' to remove duplicate lines):

- I had bitcoin-qt crash with a "Segmentation fault" error when I tried to open the 'options' dialog. Sometimes I'm able to see the options dialog, and sometimes it crashes when I try to open it. I tried re-running bitcoin-qt, then immediately did settings->options, cancel, settings->options and it crashed then, after working the first time. I've rebuilt with debugging symbols and got a stack trace:

I then tried renaming my ~/.bitcoin/ folder and restarting. After that I had a much harder time getting it to crash. The options dialog appeared fine 5 or 6 times. I encrypted my (new, empty) wallet, and everything was still fine. Then I tried to change the passphrase a got a different crash: Creating accessible with different object than the original interface!

3) Once again, even if we were hashing to form an attack, it would be like trying to create a block with difficulty 2^256. We're having trouble with just 400,000. The way the math works, our computing speed is pitiful, a tiny drop in the ocean, compared to what you need to mount a successful attack. If our computing power continues to raise EXPONENTIALLY for HUNDREDS OF THOUSANDS of years, then maybe we would begin to cover a small fraction of all the possible hashes.
SHA 256 is secure. Very secure.
If we use Moore's law, which says that processing speed roughly doubles every 2 years and the current network hash rate of 10 Ghash/s, we see that within 400 years we'll be able to crack SHA 256 in a day: >>> giga = math.pow(10,12)
>>> current_hash_per_second = 10 * giga
>>> current_hash_per_day = current_hash_per_second * 60 * 60 * 24
>>> search_space = math.pow(2,256)
>>> math.log(search_space / current_hash_per_day, 2) * 2

I wonder why the operator runs this service for free? Is he crazy??  Britcoin's help page used to say: Britcoin.co.uk is my decision to provide those living in the UK with a free exchange in order to promote awareness in the UK and allow UK residents to not miss out on the benefits of using bitcoins and being part of this great social change!
https://intersango.com/fees.php says: Right now as an introduction to the community, we are running a completely free service. We take no commission.
and: Our fees are subject to change and may change without notice. The fees which we have control over will be properly displayed and with adequate forewarning (at least 1 week).

In the bottom right corner in the 'additional links' box, "its" is spelled wrongly:

Interesting idea! :-) You would probably have to monitor though, whether you get enough funds this way and maybe turn it of if it's too much and add extra transfers if it's not enough. Given that transactions are still really cheap, I don't think I would go to the trouble of that. Neat trick though. =)
What's "too much"? What's the downside to having funds held by the 'green' address? |

@BTCSports,
Since I think you know a lot more about how betting works than I do, I would like your input on how to structure the bet.
I am saying that Bitcoin will outperform ALL of them.
How I imagine it would work is if the current (easy math) price of each is:
Bitcoin is $10.
Silver is $50
Gold is $1500
Dow Jones 10,000 points
Nasdaq 2,000 points
USD is $1
in two years if everything doubles (except the USD will still be worth $1USD) to:
Silver is $100
Gold is $300
Dow Jones 20,000 points
Nasdaq 4,000 points
Bitcoins would need to be more than 100x more ($1,000 a coin) for me to win the bet.
Please let me know if anything is not clear, or you think I am missing something.
Couple of mistakes there. Twice $1500 is $3000, not $300. And if everything else gone up 100% and we want to outperform it by 100 times, we'll need to go up 10,000%, which would take the price of BTC from $10 to $1,010, not $1,000. Going to $1000 from $10 is 'only' 99 times more of a percentage gain than gold made. |

Thanks for the bug find... I'm working on it.
Please don't use v0.1 to V0.4
Perhaps you should edit your first post in this thread to say that. I had to get to page 3 before seeing any kind of a warning. |

Currently Instawallets green address transfers require 2 transactions (from the specific wallet to the green address and then from the green address to the destination).
Note though, that this technique doesn't necessarily require 2 transactions. The green address could be replenished only from time to time with a single large transaction. But that is an optimization that I haven't implemented yet.
How about if you were to direct the 'change' from all withdrawals to your green address. So even if I do a regular withdrawal, the change gets returned to your green address. That way you should get away without ever having to manually 'replenish' the green address. |

Checking the same getTrades.php API now shows that the trades at 8.5, 10.5, 12.5 have disappeared from the trade history: This is the same time period as I pasted a couple of posts up from here, and now only the nine 5.5 trades still exist in that time range: {"date":1315753350,"price":"5.51206","amount":"0.51","price_int":"551206","amount_int":"51000000","tid":"1315753350870615","price_currency":"USD","item":"BTC","trade_type":"ask"},

Did an explanation from MtGox appear anywhere, whether official or unofficial? |

If you ignore the dollar price and just look at the cents, it's a very smooth price movement. (  .50227 to (5).50227 to (12).50028. I wonder what kind of a programming error could cause this. |

Mt. Gox isn't saying what their FOREX fees and spreads are. If they're buying and selling currencies with no spread and no fee other than their Bitcoin trading fee, they're exploitable.
They don't say, but if you look any non-USD orderbook you can see by the gap between bid and ask prices that they're charging 2.5% on all non-USD trades in addition to the 0.6% or so commission. So they're fine so long as they're within 3% of the correct price. |

'Price' box looks good.
Thanks. Impressive to get requested features implemented and live within 24 hours.  Just please dont rush and Gox things up! Good point. I'll take a few days off before adding any more features. |
