Hi, 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. https://scarybeastsecurity.blogspot.com/2021/05/recovering-lost-treasure-filled-floppy.html tells of doing this with an oscilloscope allowing the recovery of some old assembly code where the flux signal from the drive was too corrupted.
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. https://www.honeycomb.io -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-02-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
