inb4 inevitable "MY BRAIN WALLET WAS HACKED!"

Hello,
I followed the bitcoin community for some weeks and have finally set up  my mining rig (a 5870 and a flashed 5850, more cards comming). This is my first post here.

I use LinuxCoin and have been using the poclbm miner, which went quite well.
Now I want to switch to phoenix, but I get the error  "FATAL kernel error: Failed to load OpenCL kernel!", both with phatk and poclmb kernels.

I find this strange, since the poclbm miner uses the same OpenCL library and works fine.

Can anybody help?
Thanks,

Never. Even if the whole generating network was behind it, it would probably never even stumble upon a previously used address, much less one that is worth more than the number of blocks it could have generated instead. Generating blocks is trivial compared to this.

Their are 2^160 possible addresses. Lets say 2^32 (4 billion) people use Bitcoin and each generate 2^16 (65 thousand) address. That gives us 2^48 total addresses out of 2^160 possible. The probability of a generated address matching one of these is 1/(2^112). The probably of finding a block at 35 times the current difficulty is around 1/(2^64). Therefore, it would take 2^48 (281 trillion) times longer to find a previously used address. So if it takes you ten minutes to find a block, it will take over five billion years to find a used address.

Now keep in mind that we don't have 4 billion users, most users have far less then 65 thousand addresses, and the current difficulty is much lower then I used in these calculations. Mining sounds a lot more profitable.

NOTE: I assumed generating an address took equal time as generating a proof-of-work hash. However, I believe generating an address is actually slower since it involves both EC key generation and hashing.

Hey guys,

This seems like great stuff but I seem to be struggling to utilize this and that.  I am very newbish to linux but I have used a fair share of command line in windows myself.  

Firstly, I saw the persistence guide a few moments ago and followed it up until the point where I am asked to open a root terminal ( I am certain I opened a root term ) and enter sudo su- df.  I have tried several variations of this command and have come up with 'unknown user: df' as the most promising and 'unknown command' as the most common.  I don't know if anyone else came across this error, if it is some mistake on my part or whatever.  Any help would be appreciated, thanks

I am excited about .2b, I wasn't able to get mining going in .2a, I did 'start_mining' but I think I may have been missing what to put into the 'kernel' portion.  I tried opencl and something else having to do with phatk or something (words found through searching), but had no success.

I have had a lot of trouble with phoenix. The biggest issue being that it oftens gets stuck on "[0 Khash/sec] blah blah" and never reconnects to the server. This is especially bad when I have torrents running, even when I limit torrent traffic. The only reason I put up with it is because phoenix supports the phatk kernel, which gets me an extra 20MH/s per card.

Well, I got tired of it, so I forked poclbm and hacked it to support phatk. Here's my fork:

https://github.com/progranism/poclbm

So far so good, poclbm is happily running without any issues whereas my phoenix instances are freezing up  MH/s is about the same. 339 MH/s instead of the 340 MH/s I get on phoenix. Close enough.

Lemme know if this helps anyone else. 

hugolp,

can you share how you installed catalyst 11.6 on a linuxcoin 0.2a?

TIA
