Summer started on campus

Campus emptied out within a weekend. Library is eerily quiet. I walked to the lib and pick up a book by tony Wagner titled  creating innovators. The book try to use qr code to enhance the printed page. 15 century technolog-The author lamented.  Bit the first qr code I try to access did not work!  So the printed technology works because it is cheap and reliable. The new tech has to be better on both to replace the old one. This is an example of creativity interfere with usability. Ironic.
