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.

Well, to be fair, most people don't even know what a kernel panic is - or what it means...

Most OSes just do something fancy, like 'bluescreen', or reboot.

the BSOD is actually pretty advanced.

Considering it does it in the users own language and logs the result in the event viewer.

But hey lets just vote me down.

Works pretty well for Windows. You keep on slagging off the OS but it does these important things well ;)

The primary storage medium is already known, so as a programmer myself ... writing log.txt to the root partition should be f--king trivial.

I cannot fathom why anyone would think this is difficult to do.

Your KDL is caused by an issue relating *to* storage. How do you propose writing anything to the disk?

Your KDL is caused before any relevant busses are enabled. How do you propose writing anything to disk?

Why do you feel the need to make this volume of posts on one single topic without introducing anything new?
