Happy Birthday Barcode! (Google helps celebrate)
Have you noticed Google’s new look today?
Techcrunch has the scoop on why the site updated today’s homepage “doodle” to display a barcode:
Google’s new logo is a barcode which, as far as we can tell, says “Google.” Today is the 57th anniversary of the first patent on the bar code. Inventors Norman Woodland and Bernard Silver filed the patent on October 1949, and it was granted, No. 2,612,994 (pdf), on October 7, 1952. The original patent was for a system that would encode data in circles (a bulls eye pattern), so that it could be scanned in any direction.
The barcode on the Google homepage is Code 128 encoded, which is a standard way of encoding ASCII character strings (ie. A-Z, a-z, 0-9, etc.) into a barcode. It would be safe to assume that Google used their own open source barcode project, ZXing, to generate the barcode. The same library is used in Android for barcode recognition.

I love his music, but music reviews are not what I do best. Instead, to give you an idea of why I <3 Chris, I’m “borrowing” from another TV institution. Today’s installment of Inside the Bloggers Studio will be prefaced by my own “Top 10 List”. [click on the star image to read more]
Inside the Bloggers Studio: Meet Mitch Wagner
I’ll be honest with you. I’d planned to write a riveting mini-bio on today’s featured guest, Mitch Wagner.
See, Mitch is an incredibly interesting guy. It’s only fair to write something incredibly interesting about him then, right?
But Mitch had to go ahead and – *gasp!* – upstage the blogger.
That’s right. You heard me. Upstaged. Me. I can’t compete with Mitch’s answers . Anything I could write would pale in comparison. [click star to read full post]
