Science doesn't stop, but blogging occasionally does. Some good posts are on the way, but for today I have something fun: QR codes. You may recognize them as those little matrix barcodes that carry text, numbers, binary, or URLs that are starting to crop up in the real world in augmented reality or hardlink applications where objects in the physical world get linked to the digital world. If you didn't know already you can use your phone or camera to read these things no matter where you see them. They can carry quite a bit of information and because of fault tolerance and error handling in some cases portions of the QR code can be lost and the data still read. I made a few artistic renditions of a QR code that link to The Astronomist. I removed some of the bits from the center and replaced it with an A and I found I was still able to read them handily with the code scanner on my iPhone so I assume they aren't corrupt. Now I just need to make some stickers out of them or something so the digital and physical world will meet at The Astronomist.
