Shame on you O’Reilly!
I have a bone to pick with the mensa that decided that it was important to give each Railsconf attendee a badge that had all of their personal information encoded on a barcode on the back side.
From the back of the badge:
“Your name, email address, job title, organization, address and phone number are encoded on this card. Please recycle this card at the end of the conference”
What? Is there a magical card swiper that gives you money and ever lasting happiness? Exactly why do I need to carry around a badge with all that information? Do they really expect me to give it back to someone else for “recycling” at the end of the conference? This is one badge that is going in the shredder!
