How do I reliably and efficiently hash a function?
...ing two alternatives:
1. Use `attr`, and override `print.function` to not print my
attribute. However, I?m wary of overriding a core function just to
implement such a little thing, and overriding this function would
obviously clash with other overrides, if somebody else happens to have
a similarly harebrain idea.
2. Use C++ to retrieve the SEXP to the body of the CLOSXP that
represents a function, and use that as a key in a dictionary. I
*think* that this robustly and efficiently identifies functions in R.
However, this relies quite heavily on R internal implementation
details, and in particular on t...

Why not use your own S3 class?

Should VMs' IP addresses be on the same subnet as the Dom0 and other boxes on our LAN?
Hi.
I''ve installed our 1st Virtualized server using Xen. I''ve managed to
create & populate a VM that''s going to be used as our office mail
server.
Everything seems to work ok -- I can send/receive email to/from the
''real world''.
I''ve read a bunch at the Xen wiki about routing, and bridging, and
security. Wow! Lots of stuff to digest
