“They used physics to do it” is just a laughably pathetic motivation. Nobel hated “abstract wankery” or “intellectual masturbation” and wanted to promote results which benefitted the common man and society directly. This is incidentally also why there doesn’t exist a Nobel prize in economics. The nobel prize comitte has since long abandoned Nobel’s will in this matter and it is anyones guess what the order of magnitude of spin Nobel’s corpse has accumulated.

jfs+lvm on personal machines, ceph on storage, I used to use zfs on solaris and freebsd but haven’t touched it in linux (there isn’t any good reason, and I prefer to not break licensing)
