If you'd like to hear more on this, they had a long talk with the author of this piece in episode 7 (titled "The Only One") of Colour Code, a podcast also from the Globe and Mail:
From the paper, the IST on the graph stands for "Initial Speech Transcription", and those data points are for the speech-input text before any corrections were made. The other "Speech" data-points include time to make corrections either by using the keyboard or using speech recognition.
I agree, it looks great. Funnily enough I didn't even notice until you mentioned it.
However, I have to pedantically point out that the Markdown is not 100% visible. The author made the correct choice and just showed links as links instead of the raw Markdown syntax.
For what it's worth, it used to be pretty standard to put the ToC at the back of the book when making epub and mobi files.
We did it at Leanpub, and I'm pretty sure we were just following what the Prags and (if I remember correctly) O'Reilly were doing.
The reason was that opening an epub and flipping through a long ToC before you get to the book is really annoying. There is a way to set the "starting page" in epubs, but many ebook readers ignored this at the time and just opened at the title-page, so putting the ToC at the end was just a better reader experience.
Now that most e-readers use the start-page setting properly, ToCs are mostly at the beginning of ebooks.
I agree with everyone else about the physical hobbies, but I find you need something else to fill the evenings when you don't necessarily want to go outside, or when you just want to spend half an hour doing something that's not coding and not reading.
Music does that for me. If you're at all interested, check out justinguitar.com (no affiliation, just love what the guy does) and try it out. There's something about the meditative aspects of playing music that really works for me.
