OP is ~450 word announcment summarizing each half of the new book - if you're interested (hardware manufactring and hacking), you'll already know it and can skip the ads.
Amazon Affiliates get credit for purchases for up to 24 hours, including "an aggregate view of what people bought and in what quantities" (as of 5 years ago, but I believe this is still the case).

I personally believe that added value is worth rewarding but this particular blurb didn't add much. @deutronium provided more value by linking to the actual publisher's early-access e-book page elsewhere in the thread, but that wouldn't make Cory/BoingBoing any money.
Either way, I appreciate being made aware of the book's impending existence!
