I just deployed a minor update (it doesn't change anything visually), which reorganized javascript code used by the trading platform, reducing number of retrieved .js files and also minifying them. If something breaks after this one: please reload your browser, if it still doesn't help - clear the cache and reload again, if it still doesn't help - please report here  Safari, cleared cashe and reloaded. Cannot see orderbook and balances. all my stuff is gone. orders, bitcoins, positions.  |

Ya I lost all respect for his disinformation about bitcoins, talking about bitcoins going to 0 and other BS. I might need to stop following him on youtube, He probably going to get flame because his information is almost all wrong.
Of course. I also stopped following him. Make him feel the consequences of his actions. |

BrotherJohnF (also a silver-stacker, but him I still highly respect), who has earlier discussed in an interview with Chris Douane about bitcoin answered (debunked? didn't watch yet) to the Ponzi allegations by Chris in his bitcoinchannel: http://www.youtube.com/watch?v=CNLSvd4LyP8 |

You've never written a relational database application with millions of rows of data that is queried, inserted and updated at a high rate and that needs to be (pseudo) real time, have you?
you're mistaken. I designed and now maintain 2 such dbs. One of them has tens of millions of rows in some tables (this one is mssqlserver on some 2 year old 2 x quadcore). The other has millions of rows in one of the main tables. I run quite complicated search and update queries on that one (based on http requests). Performance simulations showed >40 of the most complicated search/update/insert_into_multiple tables combos per second on. While production is deployed on ok hardware (single quadcore), these performance tests were done on a fucking single ATOM 350 (dualcore) with nfs-mounted volumes (!!). No oracle magic either, just simple mysql innodb. For reference: mtgox aggregated order book (acquired by fulldepth api call) currently has about 10,000 entries. Can't be more than 50,000 individual orders in the orderbook. Maybe I'm missing something, but I still think I could do it on my nexus 4. Anyone knows how Gox moves people's deposits around? If you use http://www.bitcoinmonitor.com/ , you would notice that whenever a trade is executed, a lot of transfers take place on the blockchain, in principle it should be just bookkeeping, no real transaction should happen. I don't know why and if it has anything to do with their sluggishness. Anyone who could answer my question? No. The trade engine doesn't concern itself with the blockchain |

I thought the guys at Gox manually audit every trade before it goes through after they got hacked? That's why there is a delay (assuming what I heard is true).
I wrote that once somewhere as a joke. |

error on dynamic pricing:
i use mtgox_usd_last.
whenever is change mtgox_us_close to _ask and then change another aspect of my order (eg the fee), it switches back to mtgox_us_close which makes editing an order a pain in the asteroid.
probably because bitcoincharts.com was down |

how long does approval of mtgoxUSD code take? Is it a manual approval process?
Hello Molecular, We have daily withdrawal limit of 10 000 USD. This wasn't a problem until today. I made an informative thread here where you can track the status of your deposit and the remaining withdrawal queue to clear: https://community.bitfinex.com/showthread.php/163-Mtgox-Code-Withdrawal-queue?p=543#post543The current queue will not take more than 3 days to be processed (week-end included) I'm currently in touch with Mtgox to increase this limit. More on that later. Best regards, Raphael ok, good to know the reason. No problem really. I'll just use your exchange instead of gox  thanks for considering my suggestions regarding the lending form. |

I'm sure a lot of stuff I haven't thought about now would pop up and slow things down, but the main point still stands: it's not a hardware problem or the requirements of the problem itself, but some inefficient implementation(s) that slow things down. I agree it'd be fucking cool to put "bitcoin exchange server" app into google play store, though. |

is plain websocket still considered deprecated? On https://en.bitcoin.it/wiki/MtGox/API/Streaming I cannot find a word mentioning this (anymore). Did they finally get back some common sense? Now the next step would be to fire the PHP-kiddies and hire some experienced Erlang programmers instead to build a brand new matching engine from scratch (or buy one) *before* it all collapses under the sheer weight of unbelievable 5 orders per second. I don't know, but I heard MagicalTux is planning some updates. He's getting bashed pretty badly in the "wall thread" about the trade engine performance. Maybe he's getting rid of the socket.io (it could be a bottleneck for some reason). I don't know what it is but there must be some severe problems when you look at the machine specs: https://mtgox.com/img/pdf/20120831/Transparency.008.jpg and compare that to estimates of the order throughput that has to be digested and resulting lag that happens. |

Take this as a sort of security drill: MPEx is untouchable.
uh huh... whatever you say, kid. Redirecting DDoS traffic to a government site is poetry. Redirect or DNS change? I don't think dos-bots follow redirects. Yeah, unless the DDoS consisted of an iframe and a timer it didn't really serve any purpose other than the lol factor. I'm surprised how MPOE prices haven't being affected much, but that's pretty offtopic so I'll stop here the exchange has quite a sound security concept. People know that. |

I really hope coinlab takes over. They can't do much worse at least.
You have to give mtGox one thing: security is pretty tight. I hope this doesn't change through coinlab. It's more important even than speed. |

Nothing like reactionary upgrading.. It would be far too much work to plan and prepare ahead of time. I do understand that Gox couldn't possibly have guessed that bitcoin trading would continue to grow in volume.  Enigma Maybe coinlab is going to take over and they did not bother, who know... But yeah this is just sad... The software works, at least no mistakes known. Maybe it's only about quadrupling their hardware. They already pay $10k US a month on hardware, I do not think that is the issue. Their hardware is pathetic for a trading platform. https://mtgox.com/img/pdf/20120831/Transparency.008.jpgEngima What? I'm of the impression I could code an exchange on my phone that runs faster... this may be naive but still: I don't think this is a hardware problem. |

is it possible the server is down? that's what the app tells me after about 3 minutes or so. Confirmed; same observation here. The server was unreachable for 2-3 hours, which is about the response time from the service provider. This reminds me that it is about time that I run a second redundant copy. However, everything is back to normal. Yeah, I thought I heard you changed some stuff in order to make it easier to run multiple servers... it'd be awesome if you took advantage of that. Don't know about how big a beast is needed, but I'd be happy to chip in some coinage to make it happen. Would hate to have it go down in the middle of some deal when I'm on the run... |

S3052, we seem to be spiraling hiring on steady volume. That is, the same amount of voluming is causing bigger and bigger dollar jumps in price. It **feels** like our foundations are getting thinner. Or is that only because I am looking at absolute dollar change and not percentage change?
Does Elliott Wave speak to this issue?
Typically, it is better to look at currency volume vs. number of shares or bitcoins in this case (as long as tge currency is rather stable.. and at least for now, the USD is rather solid, despite all the doom sayers)One question from an ignorant subscriber: The possible triangle, what are the probabilities of that resolving up or down respectively? |

Wonder if you would be interested in estimating early adopters' reserves again? I have not finished downloading the blockchain yet.  Yeah, I'm generally interested. Just need a couple of quiet hours and the muse to kiss me. Been thinking about this. this http://statistics.ecdsa.org/ would tell us the info if it was up-to-date. Maybe we should pester ThomasV (?). |

Wait, so a DDOS attack is a "hack" now?
It seemed like a hack to me for a while because of the redirect I didn't know was put in by Mircea. |
