1  Bitcoin / Pools / Pool share probability simulation on: August 09, 2011, 08:20:54 PM
I should really know this myself, but I can't wrap my head around it.

The probability of a share finding a block is 1/difficulty, right? (So that on average there are 'diff' shares per block.)

Now, what probability distribution does this lead to? (It can't be pure Gauss...) Poisson?

And furthermore, if I want to do some simulations, how do I generate random "total shares" so that they follow such a distribution?

2  Bitcoin / Bitcoin Discussion / Description: Generated ?? on: July 24, 2011, 04:51:13 PM

I just fired up my bitcoin client to check my new mining payouts (from pools) and found a new entry that just says "Generated". It is about 0.44 BTC.

It appears neither in "Sent" nor in "Received", only in "All Transactions".

What is this?
3  Alternate cryptocurrencies / Mining (Altcoins) / [SOLVED]pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code on: July 14, 2011, 01:30:44 AM
Ok, so I am closer to mad than usually. I keep getting the following error:

pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code

Now, all of the following work just fine:
  • fglrxinfo
  • aticonfig --listadapters

Also LD_LIBRARY_PATH is set:


And (most importantly) the ICDs are installed:

$ ls /etc/OpenCL/vendors/
atiocl32.icd  atiocl64.icd

What am I missing?  Angry


4  Other / Beginners & Help / Donations... really? on: July 04, 2011, 08:37:16 PM

I really don't get how everyone is putting a "liked my post? donate!" in their signature. I mean, come on, wtf? Now you expect me to pay you because you voluntarily decided to express an opinion and it wasn't total crap?

What's with the greed, dude...

Seriously, how much do people expect to make this way? A dollar a week? 1.20$?

I propose an unconditional, unlimited ban for everbody having a bitcoin address in their signature!
