Moon over Soho [book review]

London by Delta, Dec. 14, 2011

A book from the pile I brought back from Gainesville. And the first I read, mostly during the trip back to Paris. Both because I was eager to see the sequel to Rivers of London and because it was short and easy to carry in a pocket.

“From the figures I have, I believe that two to three jazz musicians have died within twenty-four hours of playing a gig in the Greater London area in the last year.”
“I take it that’s statistically significant?

Moon over Soho is the second installment in the Peter Grant series by Ben Aaronovitch. It would not read well on its own as it takes over when Rivers of London stopped. Even though it reintroduces most of the rules of this magical universe. Most characters are back (except for the hostaged Beverly) and they are trying to cope with what happened in the first installment. The story is even more centred on jazz than in the first volume, with as a corollary, Peter Grant’s parents taking a more important part in the book. The recovering Leslie is hardly seen (for obvious reasons) and heard, which leaves a convenient hole in Grant’s sentimental life! The book also introduces a major magical villein who will undoubtedly figures in the incoming books. Another great story, even though the central plot has a highly predictable ending, and even more end of the ending, and some parts sound like repetitions of similar parts in the first volume. But the tone, the pace, the style, the humour, the luv’ of Lundun, all are there and so it is all that matters! (I again bemoan the missing map of London!)

“For the first nine years of its existence, aside from being appointed the flagship, there was nothing particularly special about it, from a statistical point of view.”

A book I grabbed at the last minute in a bookstore, downtown Birmingham. Maybe I should have waited this extra minute… Or picked the other Scalzi’s on the shelf, Lock In that just came out! (I already ordered that one for my incomiing lecture in Gainesville. Along with the not final volume of Patrick Rothfuss’ masterpiece, The Slow Regard of Silent Things, which will just be out by then! It is only a side story within the same universe, as pointed out by Dan…)

“What you’re trying to do is impose causality on random events, just like everyone else here has been doing.”

What amazes most me is that Scalzi’s redshirts got the 2013 Hugo Award. I mean, The Hugo Award?! While I definitely liked the Old Man Wars saga, this novel is more like a light writing experiment and a byproduct of writing a TV series. Enjoyable at a higher conceptual level, but not as a story. Although this is somewhat of a spoiler (!), the title refers to the characters wearing red shirts in Star Trek, who have a statistically significant tendency to die on the next mission. [Not that I knew this when I bought the book! Maybe it would have warned me against the book.] And redshirts is about those characters reflecting about how unlikely their fate is (or rather the fate of the characters before them) and rebelling against the series writer. Ensues games with the paradoxes of space travel and doubles. Then games within games. The book is well-written and, once again, enjoyable at some level, with alternative writing styles used in different parts (or coda) of the novel. It still remains a purely intellectual perspective, with no psychological involvement towards those characters. I just cannot relate to the story. Maybe because of the pastiche aspect or of the mostly comic turn. redshirts certainly feels very different from those Philip K. Dick stories (e.g., Ubik) where virtual realities abounded without a definitive conclusion on which was which.

big data, big models, it is a big deal! [posters & talks]

bdbmbdGreat poster session yesterday night and at lunch today. Saw an ABC poster (by Dennis Prangle, following our random forest paper) and several MCMC posters (by Marco Banterle, who actually won one of the speed-meeting mini-project awards!, Michael Betancourt, Anne-Marie Lyne, Murray Pollock), and then a rather different poster on Mondrian forests, that generalise random forests to sequential data (by Balaji Lakshminarayanan).  The talks all had interesting aspects or glimpses about big data and some of the unnecessary hype about it (them?!), along with exposing the nefarious views of Amazon to become the Earth only seller!, but I particularly enjoyed the astronomy afternoon and even more particularly Steve Roberts sweep through astronomy machine-learning. Steve characterised variational Bayes as picking your choice of sufficient statistics, which made me wonder why there were no stronger connections between variational Bayes and ABC. He also quoted the book The Fourth Paradigm: Data-Intensive Scientific Discovery by Tony Hey as putting forward interesting notions. (A book review for the next vacations?!) And also mentioned zooniverse, a citizens science website I was not aware of. With a Bayesian analysis of the learning curve of those annotating citizens (in the case of supernovae classification). Big deal, indeed!!!
