Feedback indicates that the Polkadot core protocol was covered in a way many students found unsatisfactory. The coverage was at times too deep (such as erasure coding math) and simultaneously didn't o…

I'm trying to go through the call stack of `ec_encode_data` using `printf` statements as the function is being called in erasure_code_perf.c.
I believe that the only two places where `ec_encode_dat…

after creation of erasure code:
encoder out1.dat 9 2 cauchy_good 9 1024 500000
if you go into /coding directory and delete one of the data file (ie: out1_k1.dat)

This is a test of raid 6 using this format:
./bcachefs format -f --erasure_code /dev/sda /dev/sdb /dev/sdc /dev/sde --data_replicas=3 --metadata_replicas=3 --data_replicas_required=2 --metadata_re…
