How would I go about doing some of these cool tricks for Linux based system?

I struggled at first reading the coin and can't really see much of it on my monitor but I know what it looks like now so I know who is legendary.

So should we test this on this actual website or should I test for vulnerabilities on a local host and the contact admin if I find any vulnerabilities on the same version? I don't want to risk getting into trouble testing on this forum just in case I do get into something I'm not suppose to unless it's allowed as long as you report it.

This guy was a legend and I can't believe that this has happened.

I wasn't really concerned if it was efficient or not I wanted to do it just for the fun and to show some of my friends I thought by utilizing the heat I could be able to turn that into electricity and probably would of used a LED light but I wasn't quite show it was possible and it sounds like after some research that it would be difficult and probably to much work for the end result.

Spending and holding I think I've spent around $150 this month alone in Bitcoin and have replaced 50% of it again.
487  Other / Off-topic / Can I use processing power to turn a light blub on? on: August 12, 2014, 12:30:14 AM
I would loved to do this just for the fun even if I would have to link up multiple computers up to each other just to get the processing power enough to light it up. Is this possible or am I not understanding something?


If this is possible how would I go about doing this?

You won't get any loan without providing good and valid collateral like suggested read some of the sticky posts and you will know what to use for collateral then.
489  Economy / Lending / Re: Need 0.1 Loan 7 days on: August 11, 2014, 11:53:50 PM
I doubt anyone would be willing to take those accounts as collateral it would require you changing the password and also changing email of all the reddit accounts otherwise you can just recover them and it is not something which can be sold instantly if needed.

I was looking forward to pvp but haven't been able to get on the site long enough to try it out so when all the bugs are gone I'll be open to playing some matches.

Almost ready to go . Smiley .

Great really looking forward to the pvp matches might add some more tension.

I'm launching a brand new one way (Btc to fiat) exchange in September, with a wide (bank-level) offer of prepaid debit cards, several withdrawal possibilities, and I would like to do some additional market study in order to adjust our offerings.
Thanks for your interest !

Thanks!

I'll be very much looking forward to seeing it launch always nice to see new bitcoin related services start up!

498  Other / Beginners & Help / Re: GPU brute forcing an encrypted wallet on: August 11, 2014, 11:27:11 PM
Does anyone have a comparison of how long this would take with a script/interpreter language like Ruby or Python, vs. a compiled and highly parallized computation on a GPU? I guess we're talking 4-5 orders of magnitude here?

Much much faster. Try 20x.
Still it will take many years to bruteforce.
Dictionary attack will be faster if they have a weak password.
Maybe you could program rainbow tables if you have many wallet.dat files to crack

The wallet.dat password is seeded, rainbow tables wouldn't help.

While there is a speed difference between Python and native code, for this particular application it's much closer than 20x. Most of the time is spent inside cryptographic code, and most scripting languages implement cryptographic primitives in native code.

Here's a comparison between btcrecover and John the Ripper, including columns which show what language each cryptographic primitive is actually written in. The interesting comparisons are the Bitcoin Core lines, which show a speedup of 2.75x from 44 P/s to 128 when going from btcrecover to JtR, and the speedups that you get with GPU acceleration (pretty good speedups with Bitcoin, but a measly 4 - 6x speedup for Armory which uses a memory-hard KDF).

All of these tests were run on my aging i5-2500k and 2x 560 Ti's. Wallets were created on the same system using default KDF parameters, except for the Blockchain.info wallet with 10,000 iterations (10 is the default).

BBcode tables are pretty ugly, the original spreadsheet if you want to see it is here.

Awesome domain could be good for displaying the amount of transactions, amount transferred and other sort of stats within the last 24 hours. If you can't find anyone give me a shout and I'll do something for it.
