What software alternatives are there to ECC storage under Linux Mint and Linux Mint Debian Edition LMDE to protect against a bit flip problem?
It is known that there are other approaches besides ECC memory that can help avoid data loss due to e.g. flipping of RAM memory cells by cosmic rays (bit flip problem):
What the Bit Flip Problem is:
