No. Please don't. The book still gets updated regularly, so any copy that is not straight from the repository will get quickly out of date. (I first published this book 6 years ago. You can find pdf copies out on the intertubes that are 200 pages shorter than the most recent version.)
Also, if you link straight to the pdf you don't get to see links to my other books.
Or links to places where you can get a paper copy. Which actually earns me a couple of pennies.
So please: don't make your own link to the pdf file. Don't.
