The slides from my ChicagoRuby 2010/5/4 presentation :

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.

Ruby Code Performance Tweaks by Kurt Stephens from ChicagoRuby on Vimeo.

Excellent introduction to Ruby MRI’s GC and memory debugging:

Interesting video about the relationship of body weight and optimal body position related to generalized center of mass and the angle of the pedal during the top of the stroke. Sheds some light on the KOPS (knee-over-pedal) myth.

I’ve been riding as forward as possible to get my body weight forward of the bottom bracket and over the pedal at the “11 o’clock” position. A more forward position helps keep cadence up in preparation for transitioning to running and makes it easier to get up out of the saddle.

“If you have to steal the bedcovers back from your stuffed animals at night, you’ve got bigger problems than being cold.”

There’s a bunch of minimalistic technical slide tools out there.

I’m using Scarlet, so far I like it — simple Textile markup and it uses Pygments for code syntax coloring. I’m using ERB to generate the textile markup, which allows me to generate some slides programatically.

UPDATE:

I ended up returning the N900. I thought I would give it a try as just a super-portable computer, but the media player would skip and often stop when using A2DP headphones. I hope some of these issues get resolved — I will certainly reconsider this device in the future, if it could replace a phone.

Album released on iTunes. I hate iTunes, but now people can get this album.

More Baltimores stuff to be released soon.

Thanks, Dave!

Ruby rational.rb clean-up and the Fixnum#gcd primitive was refactored into a new MRI extension. Fixnum#gcd is now defined during require ‘rational’.
