This year I'll be presenting two tutorials on building desktop GUI applications with wxPython.

There are only two days left to register at the early-bird rates. The rates go up after Wednesday!

Malcom Gladwell's latest book is a selection from his New Yorker columns. The underlying theme is what I call "wrong correctness," which is fascinating because there are enormous possibilities to be mined, but only if we can learn how to create a new approach to business.

Recently, at Devoxx, it was announced that Java would get lambda functions (a.k.a. anonymous functions or closures). There are many ways of implementing these on the JVM. This post proposes that reifying lambdas is a good choice.

The story of my visit to Poznan, Poland, for the RuPy 2009 conference. Also, a link to my talk slides/script.

Using Scala to make your code lovely

A happy little voyage of discovery down the Groovy road.

Reducing accidental complexity in Scala

A short note about a task I am doing at my day job, involving making sure that different caches are cleared consistently. For people wondering about real-life use cases of metaprogramming techniques.

Some musings about my personal history with inheritance and interfaces, solicited by the release of the Go language this week.

I drove down to Boulder last weekend to participate in an open-spaces Python conference, speak at an eyes-forward programming conference, and attend a workshop on TurboGears 2. Here's what I learned.
