Yes, it matters. A lot. Salted means you have to crack each password individually. You have to run through the entire list of candidates (until a match) for each and every salted password (given unique salts). With unsalted passwords you can run through the wordlist once, and get all matching passwords with a single MD5 run for each word in your wordlist. It doesn't matter for one single password, but for 60000 salting means 60000 times more work. And salting renders rainbow tables useless, because you'd have to build one rainbow table for each possible salt.
Thanks for this explanation. For implementation purposes, how would a website use a unique salt? For example, when the username types in a password it must be joined to the salt and then an MD5 algorithm ran over the product to compare with the database stored hash. Somewhere then the salt must be stored, right? |

where is user of number 51190 in the file?!
This is the most brilliant insight I've read so far. The hacker likely had a login on mtgox and probably deleted themselves before release. That said, 51190 is in there: 51190 tgibbsz32 tgibbsz32@gmail.com $1$9eZ.kSvA$fshZ6R1jkNtlllW10Sxpp/ |

I just received this email from mtgox.
I haven't gotten mine yet, but I like that they at least own up to it. |

I guess so, because after I uploaded my wallet.dat all my coins where gone...

Breast milk? Got hepatitis? Want it?
Animal milk is safer.
FUD. |

Maybe it is breast milk or something weird like that.
There was a show on NPR where people were eating breast milk cheese. It made me want to stab myself in the face. It really is a strange time we live in when consuming milk from animals is considered more normal than breast milk. |

Just wait until the first buffer overflow exploit in the client. Then things will really get interesting.

I fully endorse this thread.

I did, it's a joke.
there is a "wallet verifier" that lets you upload your wallet.dat to have it checked for malware...
Did you have any malware? |

As an investor, I find this thread horrifying. The OP brings up an excellent point and any rational person would have dropped the political forum and replaced it with a merchant forum immediately. The fact that this wasn't done shows that she is correct in her assessment.
There is no better way to kill an initiative than to marry it with a political idea that the masses find repugnant. Bitcoin is a great idea, but it's not irreplacable. Especially now that the way to viral success has been revealed, you can bet that among the various spinoff projects there are quite a few successors being built. The way for Bitcoin to grow rather than to be replaced is to be as politically agnostic as possible and focus on the merchants.
Moderators here need to step outside, take a breath of fresh air and talk to real people...not those in the same echo chamber.

Jessy:
Nice meeting you at the Bitcoin Meetup. From reading the forums, I'd bet on the low end of your 20-30 year old sweet spot currently. Being pretty close to your target demographic, I have to disagree with the lack of interest in Bitcoin. Speculation in unproven technology is precisely what attracts investors. The mere mention of Bitcoin to anyone in a hedge fund creates an intense conversation and weeks later leads to more questions about how to buy them.
There is slow adoption among my friends, but the interest is growing. The problems you allude to may be real in that Bitcoin is viewed as an investment. They are therefore being stored away for an unspecified period of time in the future. That said, once Bitcoin becomes more stable I think you are well positioned in that investors will want to take out profits and use them to buy directly. I think I covered the reasons why in the meeting.

the biggest issue I see with Bitcoin is security vulnerabilities.
Agreed, this is my biggest concern. |

A healthy amount of suspicion is always a good thing. That said, my withdrawals from Mt. Gox took anywhere from 30 minutes to 28 hours to confirm.

Did you get this working?

I tested the idea with a reader I bought used. It was not easy to get working under Linux, But I did finally make a cool unlocking system for my laptop. At that point there was nothing to do but try breaking in. I'll be damned if I did not get in about 10min later. The solution? I dusted a fingerprint with graphite dust, then lifted it with tape and attached it to paper on my finger. That's it. Way to easy to defeat.
I work in the banking industry and get fingerprinted regularly. Might as well skip the fingerprint part, which would leave just a PIN protecting the bitcoins. |

The US will criminalize bitcoin, it's only a matter of time. The more interesting impact is how much effect they will have on partner countries to criminalize it as well. Given the amount of influence the US currently wields in the banking industry, this is likely to be large.
An interesting thought experiment is how large of an economy Bitcoin would have to be before US officials take notice. Before e-gold was shut down, it has ~$600 million in their accounts. In order for Bitcoin to become a similarly sized threat each coin would have to be valued at $82US.

Which country did you have in mind that would be criminalising Internet tokens?
Seems a far-fetched notion, but some countries have some pretty messed-up laws these days.
The US will be the first to criminalize it. |

Maybe it is a measure of Bitcoin's potential... you don't get scammers if there is no value or worth...
heh, on the other hand, maybe it's a nail in the coffin.  |

Another idea to give names basing on how many times you have to divide Bitcoin by 10:
1 Bitcoin = Bitcoin
1/10/10 = 0.01 Bitcoin = Dibit
1/10/10/10 = 0.001 Bitcoin = Tribit
Use greek prefixes mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca
by far the best discussion. it has something the other suggestions lack: - it scales - it sets the matter down to the smallest unit, once and for all - it is logical, a very important prequesite for the units that will be the most common ones once btc is widespread But bitcoins are only divisible upto 10^-8, so why not just use the atomic state of bitcoins to discuss bitcoins in small quantaties as it is a unit that can even be fairly easily be used to describe larger quantaties. This is a better suggestion, further, nobody wants to change what they are talking about every 10x. We're all used to changing every three 0's (eg, one thousand - 1,000, one million 1,000,000). I would take the OP's logic and build from the base like you. 1 bit 100 dibit 1,000 tribit 1,000,000 hexabit 1,000,000,000 nonabit This also loses the decimal completely, not sure why it's even used. |
