BitCoin: making money with DC - literally!

[dajeepster]

If there is something that makes a video card more effecient at the job of processing the problems, why hasn't a card been rolled out that works through PCIe 16x slots that does nothing but BitCoin mine instead of actually outputing video?

From an engineering and manufacturing standpoint, that would be the most expensive card in existance, and not worth it.... R&D and such... but a quick answer.. just use the video card.. already in existance .. don't have to use the video out, i have several computers that have several gpus in them, but the system is only attached to one monitor.

Or for that matter, is there a way to configure a multicore computer to do nothing but BitCoin Mine full time instead of just at "idle" times in a way that's more effecient than using your video card?

no.. gpu is more efficient.. take a look at this wiki

and then there's talk about bringing FPGAs into this which some are predicting that once that happens... it will no longer be worth while to use VGA's...

this is an email i just recieved from Mt.Gox...

Dear Mt.Gox user,

Our database has been compromised, including your email. We are working on a
quick resolution and to begin with, your password has been disabled as a
security measure (and you will need to reset it to login again on Mt.Gox).

If you were using the same password on Mt.Gox and other places (email, etc),
you should change this password as soon as possible.

For more details, please see this:

https://support.mtgox.com/....

The informations there will be updated as our investigation progresses.

Please accept our apologies for the troubles caused, and be certain we will do
everything we can to keep the funds entrusted with us as secure as possible.


The leaked data includes the following:

- Account number
- Account login
- Email address
- Encrypted password

While the password is encrypted, it is possible to bruteforce most passwords
with time, and it is likely bad people are working on this right now.


Any unauthorized access done to any account you own (email, mtgox, etc) should
be reported to the appropriate authorities in your country.


Thanks,
The Mt.Gox team

Mt Gox is a bunch of amateurs. They used MD5 for hashing the password. They are trying to say that isn't that bad because it was salted but with GPUs(exactly what is used for bitcoin), cracking these password via brute force is not difficult.

Someone has already tried to access my Mt Gox registered email address using the password I had with Mt Gox. Makes me glad that I use different complex password for every website I visit.

My password for Mt Gox wasn't as complex as it could have been but I certainly didn't expect them to be able to crack my 8 character password that had upper, lower, special, and numbers. They must have done it in a day because why else would they be trying to login to my email account without it. I was about 15000 down the list. So I imagine they have already hit the 15000 people before me.

my email was on there too... i recieved an email from my email account yesterday saying that there was suspicious activity on my account...

Same here with my gmail account. I'm guessing my MTGox passwd was cracked and they tried to use it against my gmail account. Luckily I use a completely different gmail password. Gmail still made me change it but I changed it back after logging in. The gmail access history showed only session originating from my IP address so I should be safe.

No, there is a Gmail employee involved with Bitcoin, he got the CSV file going around on bitcoin.org and he pre-emptively flagged all the accounts in the leaked file to have password changes in the hopes people would all change their password in case it was the same as what they had on MtGox.

Here's the Google guy's post: http://forum.bitcoin.org/index.php?topic=19641.msg245983#msg245983
