Welcome to the February 2014 edition of the Gwern.net ML; the previous was January.
The purpose of this mailing list is to be a summarized version of the site RSS feed (which lists every patch), overlapping with my Changelog page, but in a push/notification medium rather than pull. It includes material from my Google+ & the LW media threads.
Writings
-
Radiance: finished
-
Public release of the Mnemosyne spaced repetition dataset (18GB of 121.2m flashcard reviews, collected ~2004–102014)
-
verse: obituary for my dog; a poem apropos the end of Genshiken Nidaime
-
A/B testing: header capitalization finished (result: upcase title & all section headers); began table of contents placement
Media
Links
Politics/religion:
-
Some thoughts on education and political priorities (Amazingly synoptic read from Dominic Cummings: physicists, psychometrics, education, experience curves, Fermi estimates, teaching high-IQ students, behavioral genetics—he’s got everything. LW discussion, Guardian)
-
“$0.60 for cake: Al-Qaida records every expense” (Principal-agent problems—because terrorism is not about beliefs; see also “An Economic Analysis of the Financial Records of al-Qa’ida in Iraq”)
-
“Appendix F—Personal observations on the reliability of the Shuttle” (Feynman’s classic appendix on the Space Shuttle program is worth a read if you’ve never gotten around to it before.)
-
“Francisco Franco, Robust Action, and the Power of Non-Commitment”
-
“No Safe Haven: Iran’s Global Assassination Campaign” (I look forward to their version for the USA & Israel)
-
On the recent origins of ancient traditions:
Business:
-
“The Milkman Cometh: What did George Sperti have to do with America’s obsession with supplements? The long, winding tale of a clever young UC engineering student, a nation fighting rickets, and a little money-maker called vitamin D.” (rise and fall of the Vitamin D cartel)
-
“What Bad Students Know that Good Economists Don’t” (I’ve been remarking for the past two years or so that we should find it very odd that the college wage premium keeps going up even as graduation rates stagnate; I’m glad Caplan has been looking at the problem.)
Literature:
-
“You have a sad feeling for a moment, then it passes.” (Nethack essay on pets)
-
Wondermark: “Better Olympic Narratives” / #1001; “In which Athletes are overgood”
Medicine:
Psychology:
-
“Maxims or Myths of Beauty? A Meta-Analytic and Theoretical Review”, et al 2000
-
“Hints of genomic dark matter: rare variants contribute to schizophrenia risk”
-
“Nootropics surveys and results” (I also did a multi-level model analysis of the data)
Statistics:
-
Lies, Damned Lies, And Social Media (Part 5 of ∞) (rape statistics)
-
Beware Mass-Produced Medical Recommendations (I disagree on the benefits of vitamin D for all-cause mortality; see my comments)
Science/technology:
-
“A Star in a Bottle: An audacious plan to create a new energy source could save the planet from catastrophe. But time is running out.” (ITER fusion research update; some shades of Radiance/NIF in there…)
-
“On the Statistics of Individual Variations of Productivity in Research Laboratories”, 1957 (discussion; see also “Age and Outstanding Achievement: What Do We Know After a Century of Research?”, 1988)
-
Fully Decentralized Bitcoin Prediction Markets:
On-blockchain transactions. The key idea is how judgment of a prediction market is carried out: holders of ‘truthcoins’ submit encrypted votes 1/0 on every outstanding market, and rather than a simple majority vote, they’re weighted by how well they mirror the overall consensus and paid out a share of trading fees based on that weight. This punishes deviation from the majority and reminds me of Bayesian truth serum. Very clever. I haven’t been too impressed with the Bitcoin betting sites I’ve seen too far (some of them like Bets of Bitcoin are just atrocious), but this seems like a fully decentralized design. The problem is it’s so complex that I don’t see anyone implementing it anytime soon.
-
“The recent ‘How Quantum is the D-Wave Machine?’ Shin et al paper” (If I had D-Wave shares, I would be selling at any price.)
-
“Little’s Law, Scalability and Fault Tolerance: The OS is your bottleneck (and what you can do about it)” (possibly obvious notes on server scaling to anyone working on big services, but I liked the use of Little’s law to structure the discussion.)
Misc:
-
“Don’t End The Week With Nothing” (Portfolios and working in public.)
-
“What the Tortoise Said to Achilles”, Lewis Carroll
Books
Fiction:
Film/TV
Film:
-
All Is Lost: if the WP description of a 1.5 hour dialogue-less film about a small-boat disaster & survival sounds like something you’d enjoy, you probably will; Redford does an excellent job and it is interesting to watch his character think & improvise and try to master the situations he finds himself in
-
The Best Exotic Marigold Hotel: not nearly as awful and sentimental tripe as one would expect given the setting of a retirement home in India, and particularly interesting for depicting some of the struggles elderly people experience these days (not something I see much of).
