Talking about pointers and memory management, I have discussed this on here
As a CERN particle physicist I got deeply into the BOS memory management
system in Fortran.
This involved doing terrible, terrible things with COMMON blocks and
meetings at midnight at beam crossing areas.
I still am haunted by the memories.. <twitch> <twitch>
