For some reason, these slides are only available in a flash widget that's synchronized with the video. Here's a little script to grab the flash and build a PDF for yourself.
ImageMagick and swftools required.
#!/bin/bash
for s in {1..39}; do wget http://www.infoq.com/resource/presentations/Simple-Made-Easy/en/slides/$s.swf; done
for swf in *.swf; do swfrender $swf -o $swf.png && rm $swf; done
convert `ls *.png -x1 | sort -n | xargs echo` slides.pdf
rm -f *.swf.png
I agree with "teach a man to fish ...", but you know, some people are far away from the sea (linux) so just providing them with the fish (pdf) is also a good option.
