This might be the first tech book I'll appreciate more from reading online than from a printed page.

I've always felt bad about this, I'm 21, grew up with a computer etc but if I'm going to be doing a lot of reading I'll take a printed page every time.

Sometimes I feel guilty for printing out online essays etc, I'd like to try an ebook reader/kindle but I'm a poor student ^_^

Whatever you do, don't buy a laser printer. If you're anything like me, the combination of feeling a great sense of satisfaction at how fast the things are (still!) and liking reading pages more than the screen will lead you to print out everything.

↜ Invisible canvas

Haha this book looks amazing and beautiful.

It combines the right amount of clean code and tongue-in-cheek sass. Perfect so far.

Indeed, looks beautiful. Needs more Junicode though!

I love Mark's writing. I learned Python from Dive Into Python a few years back (when I was still in high school).

His writing is simple and concise. Clean, just like Python code :)

The typography here is very interesting; I'm quite curious now how the final book will look after typesetting.

I dig the multicat feature in HTML 5. I'll have to use that one.

The canvas chapter is great. Can't wait for him to finish it.

Yeah, it inspired me to spend an hour at lunch messing around with canvas. I can see some really nice uses for it as a tool for progressive enhancement—for example, you could replace a table of values with a histogram in browsers that support canvas and have JavaScript enabled.
