It sounds more like it is just a way to spam that service up for the few that find it useful. For 7 BTC I can send a block with outputs to every 3-5 character address, so now you have to remember six.

Actually, since the service is case insensitive, that makes it just Base35 you'd spam. Every 1+3 char to 1+6 char could be blasted for 18.4 BTC plus a BTC in fees to get them picked up,  and you can check the blockchain for them first and save maybe 25% too.. BTW, no need to validate a private key, just add a correct checksum to your public one (plus add your advertising message or obscenity if you suck). Now the shortest firstbits you could get would be eight digits, like 1Ef3oe2K, and for that you might as well be emailing your whole payment address.

They don't have to be too short if it's a word or group of words that are easy to remember

If you're just trying to destroy firstbits addresses, you don't even need to send a satoshi to each of them. An output of 0 is valid, and I've used it to claim a couple of my firstbits addresses. You just need enough of a transaction fee to get it relayed and into a block.

Really good tool
Can't work with OpenCL here but still working on that

That's good, but what changed?  Did you pull the git changes from Thursday 7/21 and try again, or is this with the same calc_addrs.cl that caused the segv last time?


Well, I'm stumped.  According to Apple's developer site, GLD is the modular OpenGL driver interface.  However, Google doesn't seem to know _anything_ about a "gld context creation failed" message.

What version of OS X is this?  Can you pastebin the output of clinfo?  Are you able to run any other OpenCL software on this machine, besides just the clc compiler?  Can you post a link to this compiler?

If you really think the third parameter is causing the problem, it would be a good experiment to change it to CL_QUEUE_PROFILING_ENABLE or even CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE.

Ouch.  Let me guess, nVidia?  What card and what version of the driver?

If you can, try driver 270.41.19, which is the one nVidia recommends on their CUDA site to go with CUDA SDK 4.0.  I've encountered serious problems with older drivers, but haven't tried 275.xx.

I pushed a change to have oclvanitygen report more useful error information.

Use this tool: https://github.com/jackjack-jj/pywallet

Joric didn't commit for almost 2 weeks now so I don't know if he wants to continue its development
I prefer to bring many improvements available immediately for people that might need it instead of waiting him to accept my pull requests (he looks busy with his new tool). For example my other script that gets rid of 0/unconfirmed tx's needs my pywallet fork
