Books:

• Attached, by Amir Levine and Rachel Heller, a book that challenged some of my beliefs about psychology and relationships. In particular, they argue against the usual "two self-sufficient people" ideal, saying that mutual dependency is normal and desirable. Quote: "If you want to take the road to independence and happiness, find the right person to depend on and travel down it with that person."

• Just Ride, by Grant Petersen, a funny book about cycling. He argues against the fixation on bike races, and in favor of a more casual style, which matches my attitude exactly. Although I still think synthetics are better than cotton ;)

Cool stuff online:

• The Assasin Puzzle, a cool math brainteaser from the PBS Infinite Series.

• The Non-Libertarian FAQ on Slate Star Codex. I found the "competence of government" section particularly thought-provoking.
