Hey everyone, I'm gonna help out with fixing up the Church
room tonight instead of giving the talk. I'm not sure what
programming language they're using to build the walls but
surely will pick it up quickly. Come out and help!

In general the past few months have been really busy and
I would have liked to give more workshops, but the ridiculously
hardcore machine learning class at UCB is ending soon and
I hope to pick things back up again by January.
