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.

Who thought this was a good idea?

Lets use a smart phone to decode the error message ... Why not I dunno write some data to disk? Surely that would have been simpler.

Right, because that's going to work reliably when the kernel panics.
