the old GPUs that used to pool mine before the ASIC takeover are great
for searching key spaces and permutated dictionaries, but seems the
SDR adoption is lacking.  traditionally, SDR is narrowband focused,
low overhead more than amenable to CPU cycles.  very wide band, very
high rate, multi-radio SDR setups are just now coming into independent
exploration; perhaps then old GPUs can be brought back to utility!

my favorite odd band technical input is still the barcode scanners
from decades past which would interpret scanned input and escapes same
as keyboard console entry.  factory reset SMS type attacks have been
ongoing for so many years, the same mistakes over and over.  back
then, you could claim innocent times.  today, there is just no excuse.



last but not least, regarding compromising your own devices to know
when someone might be trying to compromise your devices, the following
may be useful hints in the proper direction.  as always, best to build
your own :)
