agnosticism wins by default.
Indeed, plus we are all born agnostic. |

Actually, all these things are interpretations of certain kinds of evidence. Since we don't know how the evidence was "deposited" there, because we weren't there to observe it, we don't know if we are interpreting it correctly.
This I can't argue against, but I will say I feel more comfortable taking an educated guess by extrapolating trends instead of reading the ramblings of some old dudes about "how it all is"  . FFS most all crap written by humans (except hard engineering material) is just subjective drivel. Always has been, always will be. While the Bible leaves some of its areas open to interpretation, it is also a book of records, where people recorded what they have observed. Examine the Bible the same way you examine all science, and you will find that the Bible outdoes everything else in all areas of accuracy. 
There! I wrote down a claim in a record, do you trust I am telling the truth? Any process that requires trusting information is NOT scientific (that's an axiom on which bitcoin is constructed BTW). Also the bible has been subject to "chinese whispers" where information is corrupted as time passes. For example the 7 days of creation, the oldest known texts do not use the word "day" but "cycle". Not that it matters when the original text was just some dude writing stuff anyway. Also, Just because something is old doesn't make it better, often it makes it crapper. But lots of people think only old texts can contain truths, like the old fashioned folk were completely trustworthy and never knew how to lie in order manipulate their game, bullshit! They probably lied more profusely because it would have been more difficult to cross reference and audit back then. |

Only that for even faster performance, it would be implemented in OpenCL. Hashcat already has, though.
Of course you're right! just using PHP like pseudocode because many understand it. |

@Razicks PHP func, modified to crack a whole dbase of hashes at once: // these are the hashes of the passwords I'm trying to break
$hash_to_crack = array();
$hash_to_crack[] = '30fca77cebf16fe3c5b5b4db4371dee4';
$hash_to_crack[] = '40fceb6cebf16fec15b5b4db4371cef4';
// many more hashes, the entire dbase.
$hash_to_crack[] = '50fca4cebf146fe3c5b5b4db4371bbe4';
$attempt = NULL;
$hashes = sizeof($hash_to_crack);
$cracked = 0;
$pass = "";
while ($cracked < $hashes)
{
// $this->next_try would be a method designed to supply the next possible password.
$pass = $this->next_try
$attempt = md5($pass);
// compare the next hash to the target hash
for($hash_num = 0; $hash_num < $hashes; $hash_num++)
{
if ($attempt == $hash_to_crack[$hash_num])
{
echo("FOUND PASSWORD $pass");
echo("FOR HASH " . ($hash_to_crack[$hash_num]));
echo(PHP_EOL);
$cracked++;
}

We could get hit by an asteroid tomorrow. This is a real possibility look it up.
But don't worry this threat has been attacking the earth from the dawn of time
Be prepared for any loss of data I have been told regardless of an emp, solar flare, etc etc
Yeah anythings possible, but I consider EMP to be higher threat than asteroid. Remember nuke weapons aren't a conspiracy theory, thousands have been built and are being mantained, some old bastard warhawk may want to see a good show before they pop their clogs, you never know how it may start. Also remember that EMPs don't mean MAD (Mutually assured destruction). EMPs will be the first nuclear weapon flavors to be exchanged and could well decide the victor before the higher yield ground nukes were lit. Just one "Starfish Prime" like HEMP device would fry almost all unprotected modern microelectronics in the united states. Modern circuits, IC circuits with junctions widths in the tens of nm range are very static sensitive, back then (1962) semiconductors were big chunks of silicon in metal cans, like comparing a boulder to a microscope slide with regards strength. Starfish Prime made those effects known to the public by causing electrical damage in Hawaii, about 1,445 kilometres (898 mi) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms and damaging a microwave link.[8]
...
Newer calculations showed that if the Starfish Prime warhead had been detonated over the northern continental United States, the magnitude of the EMP would have been much larger (22 to 30 kv/m) because of the greater strength of the Earth's magnetic field over the United States, as well as its different orientation at high latitudes. These new calculations, combined with the accelerating reliance on EMP-sensitive microelectronics, heightened awareness that EMP could be a significant problem. |

...after such a storm there would be a rush among people to start their clients...
The rush for many would finish when they hit their system on switch to find a blank screen. The only way to make an EMP proof system/miner would be to have a good Farraday box with multi layer gauze air intake/exhaust. Data line can be a thin fiber optic, no problem. Power feed would need some consideration: You could have a small fuel driven generator within the box, and if you had a 15 minute warning then you could unplug the box from the mains and put it on generator power. You could even feed grid power in without exposing system to EM risk: using an electric motor that drives a generator, the mechanical coupling having a plastic section in it. Think how smug you would be to have the only running system on your block! Shame the net would be down for for quite a while after though so you couldn't troll around forums with other leet protected nerds  |

I agree that from a "risk assesment" perspective then large EM event could devestate bitcoin, wiping out alot of coin, only cold wallets saved.
So even if the chances of it happening are small, it is still a large risk because the ramifications are so high.
But seriously, what could be done to protect against it?
All that we could possibly do is minimise coin loss by having everyone physically store their private key data, this would maximise recovery attempts after EMP.
If only a few people had large cold wallets then their value would drop to near zero after EMP even if the network was re-established, because not enough people hold coin anymore.

In a world without electronics, even gold would become a worthless commodity.
Those damned pyramid building Egyptians, their habitual phone texting delayed the pyramids by ~10 years. |

It's a horrible day again. Although I have my hopes up a recovery soon (ish).
There is no known cause for these huge sell offs?
It was only a few hundred coins dropped on BTCE. BTCE has quite a thin market now. Here's a comparison post I did, you can see how arbitrage linked the hit with other exchanges: https://bitcointalk.org/index.php?topic=744449.msg8417039#msg8417039 |

OPs handle is: @falllling. So he can never be bullish, he's a perma-bear. Someone should open a nemesis account called @risssing, maybe he will as soon as he buys in |

Yes I'm guessing: someone dumped multiple piles on BTCE starting at 13:36 my time (11:36 UTC), only a relatively small dump, but stinky nonetheless, causing 25% drop as the orders buried into the book! Whoever did that could have got more fiat by dribbling in over multiple exchanges. Here's how it went down... All charts have same time periods: Going Down (over 9 minutes) Going Up (over 14 minutes) BTCE:  Other exchanges only got dented, probably by arbitrage against BTCE: BITSTAMP:  BTC CHINA:  |

...in most cases today passwords are not hashed in the database...
Unbelievable and lame. No excuse for a crypto currency site! It's so easy to add this to the PHP: $sPassHash = hash( "sha1", $sPassword ); It's not that easy if you want to do it right. Straight sha is too fast so you should use many iterations or sha2 or whirlpool. Thanks for the heads up! This stack exchange comment seems pretty thourough: http://security.stackexchange.com/questions/211/how-to-securely-hash-passwords/31846#31846 |

Very nice read on the subject: http://www.futurescience.com/emp/emp-protection.htmlI just Faraday wrapped my portable shortwave radio and Geiger counter. (Orange Alert ) Many people severely underestimate the need for information in any kind of a disaster. In recent examples of long-term disasters (such as the breakdown of civilization in the former Yugoslavia in the 1990s), many people actually died while undertaking risky activities in order to obtain information. |

Satire or not, I am so sick or these garbage threads. Moderators should start deleting them since they have no value whatsoever.
No value? Your post just earned you some coin from primedice, ka...ching! |

What is the point of creating bitcoin? Like this would make banks to bankrupt. I don't know but maybe It is not very logical to be true at least from the first look maybe there is something else deeper...
But why would they make bitcoin?
Bitcoin is against the government influence in the economy.
idea1A honeypot to test security capabilities of other nations. And what more cunning way than to have to expend zero$ on bating the trap. So maybe it's to force a hand show (of exotic systems) in the global geopolitical poker game. Highly unlikely but might make a mediocre/poor novel. idea2Slightly more likely: Maybe to beta-test a new cash system. In the future (when the beta test/development was complete) It would be easy for the government to hijack miners, gov has very deep pockets, it would only take the majority of miners to be overwhelmed by greed and all start mining .gov coin for the coin and the nice% fiat bonus on top. And of course big investors would convert their BTC into GOV, BTC might become the new DOGE, such wow! The existing fiat petrodollar IS coming to an end, eventually the game WILL be reset to some asset backed system (ala Bretton Woods) and played all over again, would be sweet for .gov (banks) to not have to dip into their gold if they can just grow a free POW network and then use that. I admit, it's a crazy speculation, but the chances of it being so are >0. It would be against their interest to create a decentralised currency, agencies like the CIA/FBI etc aren't likely to give away control of the global finance system.
Control can always be re-established with deep pockets, you really think miners are not corruptable? Their all on GHash.io because they're spooked by variance, what do you think they would do if their mining rewards were increased with fiat subsidy on top? |

Hmmmm... I see what you are saying, sorry for my prior misunderstanding amaclin  Sorry. My English is much worse than my math skills  Your English is great! I was just a dunce |

Yes, the property of collision resitance means there will only be one private key that maps to any particular public key
Wrong (same as I was) Even with a perfect hash function that has no collisions: ~2^96 private keys will map to a given public address. |
