All the raw data used to generate the graph should be referenced in the slides.

The code used to generate the slides is here:

I’m looking to increase the set of code “Problems” to cover other tiny code idioms and platform issues, for example: regular expressions, numerics, etc. If you have ideas, take a look at the code and contact me.

Justin Love gave a fantastic presentation on lambda and closure.

Thanks to everyone who came — hope it was helpful.
