How are you expected to know you need to restore from the backup if the damage is silent? How can you have confidence in your backup if damaged data can be silently written to it?

They could just checksum metadata, which is cheaper to store redundantly. ReFS already does this when you're running it on non-redundant storage - integrity streams are only enabled on mirrored/parity configurations.

Yup. Nothing intrinsic to it that needs checksums. zfs set checksum=off rpool

Don't forget if you're on a system with DTrace, Ruby supports a nice bunch of probes for various events: http://ruby-doc.org/core-2.3.0/doc/dtrace_probes_rdoc.html

The scrypt and bcrypt rates are a bit misleading because they're with unrealistically low work factors: * bcrypt: 2^5, when 2^10 or 2^11 is a much more typical figure * scrypt: N=1024 r=1 -> 128KiB. For interactive logins the recom

Sequel::Model's quite optional - it doesn't force you to use the AR pattern. It's built on top of Sequel::Dataset, which is entirely usable all on its own. ROM also uses it as its SQL backend: http://rom-rb.org&
