What have I done in May... Looking through my changelog reminds me of a few things. In reverse order:

- I've made a little more progress on the Touhou project (may've found someone willing to buy the CD-ROM for me, which would help: http://www.reddit.com/r/TOUHOUMUSIC/comments/1f61p6/request_anyone_ordering_from_tora_no_ana_soon/ )
- Added 2 new studies to the DNB meta-analysis and also a new covariate (whether payment reduces gains; it doesn't: http://www.gwern.net/DNB%20FAQ#paymentextrinsic-motivation )
- updated my analysis of SDr's sleep data (http://www.gwern.net/Zeo#sdr-lucid-dreaming-exploratory-data-analysis)
- oh wait, I did do a new project: applied survival analysis to modeling fiction reviews: http://www.gwern.net/hpmor#survival-analysis

    And in my Google analysis (which I credit to last month and not May, even if it went viral in early May), I added in random survival forests (http://www.gwern.net/Google%20shutdowns#random-survival-forests), fixing that gap in evaluating prediction methods, which was a little burden of guilt off my mind.

    While I was at it, I replicated that recent paper analyzing Bitcoin exchange shutdown or theft risk: http://www.gwern.net/Silk%20Road#bitcoin-exchange-risk The dude's since given me his source code, but I haven't tracked down the exact discrepancy yet. (What can I say? Survival analysis is a great hammer, and it cost me enough tears and sweat to learn how to use the R library that I plan to use it everywhere I can.)
- I started a little Noopept self-experiment using the Noopept someone gave me, but unfortunately they gave me too little for the results to be very meaningful (see the power analysis in http://www.gwern.net/Nootropics#experiment-2 ); but maybe they will have a trend and I can try a bigger experiment later.

    TruBrain (http://trubrain.com/) sent me a month's supply of their all-in-one nootropic, but I haven't tried it yet because it would interfere with the Noopept. I also purchased magnesium l-threonate, which is a disappointment so far, and some nicotine patches, which I haven't used yet. A small sample order from a new modafinil website selling the usual Indian Modalert is in progress but hasn't arrived yet.
- I have a weird little literature/historical/survey article in progress (http://www.gwern.net/Sand); we'll see where that goes
- I posted an analysis I wrote a few months ago in private of whether a particular vendor on Silk Road is a federal mole (probably not: http://www.gwern.net/Silk%20Road#a-mole )

Actually, I guess it was overall a pretty productive month. Probably helped that jury duty has so far turned out to be a bust: I've been on call since 21 May but have yet to actually go into the courthouse to do anything.
