comment Does a noisy version of Conway's game of life support universal computation?
Peter, if your computation succeed with probability 2/3, I am happy.

comment Does a noisy version of Conway's game of life support universal computation?
The real question here is if the stochastic/noisy versions of the "Game of Life" still support computation. (If these version support computations in P then their power may go all the way to BPP.) It is possible that the computational power of these stochastic versions of the game of life is much lower.

comment The complexity of sampling (approximately) the Fourier transform of a Boolean function
BTW, Scott, isn't the argument via permanents that shows that BOSONSAMPLING in BPP implies collapse of the PH works also for Fourier sampling?

Thanks, Scott, thhis is very interesting. I will mention your conjecture along with a few others in the next edit of the question.

comment Count the number of spanning trees fast
Doing Linear algebra with the Laplacian rather than a general matrix is often easier. I wonder if this can be relevant.

Thanks, Martin! I suppose it is not known how hard it is to sample from the Fouriet transform even of AC^0 functions, right? (In the case of depth-2 a conjecture of Mansour asserts that it is polynomial (with randomization).
