Couple of days ago I ordered a book on programming, and opted for the paperback (dead tree) version. The book was delivered to my home within two days.

People who opted for the digital download edition however, have yet to receive their download link, and are slamming the author for the faulty checkout routine... which the author himself programmed.

So now I'm not so sure whether I should trust the programming techniques as described by the author in his book.

Irony eh?
