This talk is old now, but I’m happy to answer any questions.

Someone recently did some really nice sketchnotes: https://twitter.com/deejaygraham/status/528220110331596800

Thanks for sharing those notes, it's awesome! The style of the notes remind me to the Feynman learning technique. I tried it once and still remember everything. For me it was a surprisingly fruitful way of learning.

Reminds me to this implementation on js: http://stevelosh.com/blog/2013/03/list-out-of-lambda/

Lambda is pretty cool.

This is the detailed text version http://codon.com/programming-with-nothing

A nice demonstration of lambda calculus using Church Encoding in Ruby, without saying that that's what he's doing.

I guess at the end of the video, he will probably reveal what the thing he's been doing is called.

I saw Tom give this talk at Ruby Manor. It melted my brain, but it was completely worth it, and challenged lots of assumptions I had about programming but never realised I had. Highly recommended!
