Complexity

I have a random note on my desk that I think came from a discussion at the Museum of Science Book Club for the Curious. I unfortunately didn't write down who said it but still find the thought intriguing enough to capture it here.

Is our ability to create complexity increasing faster than our ability to understand complexity?

How We Decide

"How We Decide" by Jonah Lehrer is an exploration of all the nuances that go into the decision-making process. It is an approachable blend of cutting edge science an anecdotes about how decisions people made influenced their lives (both in life-and-death situations and the ordinary). He explores the decision making process through various facets, among them: dopamine, feelings, thinking, morals, internal argumentative dialog, and thinking about thinking. I suspect a second reading is in order as I usually find reading on airplanes to be a distracting.

The True History of Tea

Victor H. Mair & Erling Hoh explore one of favorite beverages in their book "The True History of Tea." I read this book during my visit to China which allowed me to better connect with the material as I was able to visit a tea planation and see statues of Lu Yu, who is a central figure in the book. While the general outline of tea's history was covered in A History of the World in 6 Glasses, this book more richly follows its path through China, Japan, and the rest of the world. An approachable and rewarding read for any tea lover.

China

At the end of May I took a two week trip with my Mother to China. As I've been trying to do with most of my recent trips, I took a few pictures. My initial reaction to the trip was that it was good. The cultural sites in China are amazing. What disturbed me though was the visible environmental impact of China's growth. In particular visiting the Turtle-Head Peninsula it was hard to make out the islands only a few hundred yards away due to the smog in the area. I never got a good view of Shanghai's sky-line and the only nice day we had around Beijing was due to 30 MPH winds blowing all day.

Be wary of micro-benchmarks baring speed improvements

I've seen some links recently to the Round up of ActionScript 3.0 and Flex optimization techniques and practices and I'm afraid. I'm afraid that entries on that list are going to become gospel and code that doesn't use the tricks listed will be labeled bad. Knuth said it best, "We should forget about small efficiencies say about 97% of the time: premature optimization is the root of all evil." While the author frames the discussion correctly stating "You have to learn when to use some techniques and when to leave some out." I don't think he does enough to call out the type of optimization each entry is, or more importantly, how these techniques were derived.
