I found it funny to compare a paper by my colleague Andrew and this talk. Ok we used gibbs sampling and a teeny weeny sad old hadoop cluster and we were looking a phone lines and not stars, but Bayesian inference to make a single catalogue... Ours does what's this made of and where is this thing, rather than "is it a star or a galaxy"

Also ours doesn't run in 15 minutes!
