I password protected the original post (email me for the password if you are interested in reading it).  When I posted the original link on reddit/r/compsci, multiple commenters suggested that I delete the article to avoid students from cheating (which was not my intention).  I then sent an e-mail to the professors (at CMU) and they kindly replied, asking me to remove the post:

Matt,

Thanks so much for your kind words. It’s great to hear that the book is helpful to you. While every student gets a slightly different bomb, the solution strategies for each phase are very similar. So it would be good if you could remove those posts.

Thanks!
Dave
