I'm not an economist bs-filled or an economist at all, sorry for that, however I'm connected to web developing and even not being a designer. Man! You're even using Comic Sans for your headers... I really don't know what can be more amateurish than that, except maybe one or two marquees rolling without any relevant information.

So, mrb, you made a good point for use just MD5 or RipeMD
Basically your statement is: giving enough computing power and every hash can be broken.
Well, MD5 is fast, protects you in case someone had his eyes on the database, and protect the db is the realm and responsibility of the site's owner. Going further to paranoia levels, will just make you to waste electrical power for nothing.

Imagine your DR Who from the TV show with a time machine. You can go back anytime you want in 4,000 years but you don't know which year. What do you bring as a currency to trade?
But that just means one thing; gold has been around longer. Like saying that next year will appear NetCoin, it will actually take off and 100 years from now is the regular currency. A person living at such age with a time machine wants to visit our year. He would better bring Bitcoins because Netcoins are yet unknown. |

From PHP manual: die Equivalent to exit()
Description
This language construct is equivalent to exit().
Choose what alias you want to use... the header redirect with the exit() bellow terminates the code execution and redirects the visitor to that page. |

Following the events at MtGox I was thinking if it wasn't a good idea to create a Panic Button in the admin area so the site can be shutdown methodically and checked for leaks afterwards. For this I would start by creating a table, let's say "system" (name it whatever you want), with 2 fields: key - varchar(8) Primary key / value - tinyint(1) default 0 Add to that table 'halt',0 Create a static html page to tell your visitors your site is halted, like system_halted.html Right after your mysql_select_db perform the following check: <?php
$q = mysql_query("SELECT `value` FROM `system` WHERE `key` = 'halt'");
$r = mysql_fetch_assoc($q);
if($r['value'] == 1){
header("Location: system_halted.html");
exit();
}
?>
In the event of danger then call this function (adjust it accordingly to your system configuration): <?php
function panic_button(){
//Uncomment the line bellow if you use monit to check for bitcoind
//exec("/etc/init.d/monit stop &");
//Stop bitcoind
exec("/path/to/bitcoind/bitcoind stop &");
//You can add here some commands you may wish to perform along
//exec("mv ~/.bitcoin/wallet.dat /some/other/place/");
mysql_query("UPDATE `system` SET `value` = 1 WHERE `key` = 'halt'");
}
?>
Note, this is just a rough sketch, the user httpd under which php runs probably have no permissions to stop services or move wallets, so you probably would need to call another script able to sudo, and the bitcoind stop could be performed using a post request from the localhost. The whole idea is to develop a system halt that can be easily triggered and perform all halt functions at once, starting by saving the coins (mysql junk you can undo after, bitcoin transactions once in the blockchain no). |

Casey seems to miss the importance of the privacy feature of btc.
Indeed, and this feature is one of the most appreciated these days, not only for shady purposes, but also for keep our habits to ourselves. Common payment gateways all over the internet collects statistics about how, when and what you buy to send you "specific" publicity. This alone sounds like "big brother" enough! BTC brought a way of internet money to become actually money. |

Why does everybody talks about gold as if it has any intrinsic value?!  It have a conventional and relative value strengthened by ages, but no intrinsic value at all and not even many applications. To not mention "GoldMoney" is just yet another name for "e-Gold" with a nicer template... |

The salt has real value - it prevents rainbow table attacks. Without it, one could crack many passwords in a fraction of a second.
Too bad MtGox stored the salt in the password field, next to the password.  Unless you use a single admin-added salt to everyone, you need to store the salt per-user for use different ones to everybody. Also that is the way crypt returns it: <?php
$a = crypt("pass","$1$salt$");
echo $a;
will return something like $1$salt$klhi%$# (not exactly this hash output) Single salt added by config can be brutte-forced if the attacker has a hash for which he knows the password, eg for md5: Pwd: 12345 $k = 0; while($result != $hash){ $result = md5("12345",$salts_to_try[$k]); if($result == $hash) $salt = $salts_to_try[$k]; $k++; } |

Could someone who thinks that Mt. Gox cooperating with authorities is bad please tell me this:
(...)
Nobody said that is a bad thing, take the initiative yourself to go write love letters to someone who doesn't call the shots and is basically just the muscle, is. If they want to do it, should had do it the right way, and the right way starts to get consulting by somebody with forex regulation expertize and contact who's in charge of making laws and regulate markets. |

Even with the other issue you raise, wtf do you want MtGox to do? To say that they won't cooperate with authorities? If asked, there were no problems. Take the initiative himself was the foolish part, not exactly cooperate or not. Different issues. And this thread isn't about supporting M'Tux, it's about discussing it. |

Let me put this in the right perspective then; a) The police is NOT the community where you can rollback a whole day of transactions and have this one agreeing and the other against, they will just flash you a warrant and force you to do what it says. b) Financial operations are regulated by financial experts, and when you need to report something fishy you also need a lawyer to protect you from lawsuits from the angry customer you'll get afterwards. c) It's with the existing laws you need to abide, so you need lawyers and financial experts, making friends with the police will do you no good, as if you're outlawed they will pick you anyway... it's their job. This has nothing to do with being for or against the police, but MtGox/Britcoin action was pretty much childish and most likely they made no consulting with any lawyer of financial area prior to carry on with it. EDIT: Now I notice you've no idea of what I'm talking about. This isn't about they complaining to the police about the heist they were victims. I'm talking about this: http://in.reuters.com/article/2011/06/15/financial-bitcoin-idINN1510930920110615 |

@ottodv
I would agree if that was the case, I see it right for them to report unusual activity or be regulated.
However I don't see why the FBI or why the DEA, they were reacting hysterically to the reactions of two tech-savvy US senators.
They should try to apply to financial regulators, lobbying with politics, not going straight to the police offering help as if some sort of vigilante/snitch recruitment was going on.

It is not neccessarily the founder who benefits the most. Anyone in the pyramid can eventually become the largest beneficiary.
I hadn't say it is the place where you can wage more, I said it is the smartest place to be. In a pyramid the founder takes few to no risks, it's an «I give the pocket, you give the cash» sort of business. The others bellow are gambling until it stops and eventually can wage more, but are under way more risk. |

Does 80C coffee freeze faster than 70C coffee? That is really the only question left at this point
Glad to know I'm not the only freak who takes his coffee seriously. Tell me when there's a club available for me to join!  @randomguy7, Coffee doesn't, water does, so the water part of the coffee freezes faster from 80șC than 70șC not the coffee. |
