Went went to see IJK at the New Victory Theater yesterday. Each play in this series is inspired by a simple geometric concept. More or Less Infinity is about one-dimetional lines, Plan B (which was presented at the New Victory in 2004) examines a two-dimentional plane, and IJK focuses on the three-dimensional cube. With a distinctive, artistic aesthetic, the company develops an exquisite and unusual performance out of a basic mathematical idea. Loads of fun. It made me realize that Hacker-s without kids don't find out about this kinda cool stuff. I strongly recommend you look around in your city for kids shows that involve acrobatics, gymnastics, juggling, etc. It's a good brain-tickle, and usually reasonably priced.

Theory of Change (ToC) is a methodology for planning, participation, and evaluation that is used in companies, philanthropy, not-for-profit and government sectors to promote social change. Theory of Change defines long-term goals and then maps backward to identify necessary preconditions. (Working Backwards, ChangeTheWorld) https://en.wikipedia.org/wiki/Theory_of_change I don't like this phrase much, as it feels like it's about a generic theory of change-agentry, as opposed to a context-specific theory of steps to take to reach a specific outcome.

Scott Adams on Simplifiers and Optimizers (part of How To Fail At Almost Everything And Still Win Big). Some people are what I call simplifiers and some are optimizers. A simplifier will prefer the easy way to accomplish a task (SimplestThing, Satisficing), while knowing that some amount of extra effort might have produced a better outcome. An optimizer looks for the very best solution even if the extra complexity increases the odds of unexpected problems. I have a bias for simplification, but surely there are situations in which optimizing is the better play. So how do you know which approach works best in a given situation? (more)

Probably the simplest definition of a filesystem is a data structure or a collection of files. In Unix, filesystem can refer to two very distinct things; the directory tree or the arrangement of files on disk partitions. The latter can be thought of as the physical filesystem as it has a tangible physical location. http://www.uwsg.iu.edu/usail/concepts/filesystems/def-of-filesys.html (more)
