BeOS & Derivatives Michael Lotz added code to generate QR-code for the KDL (Kernel Debug Land) ouput (which pops up when the kernel crashes). No more blurry photos with debug output, but a QR code which decodes to the clear-text KDL debug output. Here's one of the relevant commits, an example showing a QR code, and text from decoded sample QR code.

Wow. That's actually pretty darn cool.


Yeah, that was my reaction too. It's not much more complicated than the traditional approach of dumping "techie gibberish" to the screen, but it does so in a way that allows that info to be copied off the machine in an error-free manner. It's a brilliant idea.
