The Archive of Interesting Code is an (ambitious) effort on my part to research, intuit, and code up every interesting algorithm and data structure ever invented. In doing so, I hope both to learn the mathematical techniques that power these technologies and to improve my skills as a programmer.

For drinkers who've foresworn a life of Sapporo and Super Dry, Tokyo is a much more welcoming place than it used to be. It's still worth making a pilgrimage to the legendary Popeye in Ryogoku, but you can now find Japanese and import microbrews on tap at many bars around the city – and some places are even starting to brew their own.
