When copying data from old floppy disks, the Greaseweazle is handy for
moving the floppy-disk controller aside and getting the flux levels from
the drive for interpretation by software but sometimes that's still too
high level.  Given floppy drives often have test points on the board,
they can be used to obtain the signal from the head before the PCB has
muddied its waters.
tells of doing this with an oscilloscope allowing the recovery of some
old assembly code where the flux signal from the drive was too

OpenTelemetry allows code to publish internal data to help analyse
behaviour and performance, e.g. logging and traces.  It's particular
handy for distributed code.  https://opentelemetry.io

Shovel that data to Honeycomb for interpretation and visualisation.

Cheers, Ralph.
