[TUHS] BSD Talk History -- Credit Where Credit is Due

[Clem Cole]

I don't remember how Kipp did it.  It would have been very V7 oriented and
using the FS and signals I suspect.  I remember is was not very sexy and
one of things sockets allowed was completely rethink.  That was the bull
session I was referring too. As for the security issue, sure - we would not
have considered that.  Again we were grad students and basically friendly
so actions like that would have been considered uncool.

As I have pointed out elsewhere when a connection to the ARPAnet cost
250K/yr per host and a host cost $1-4M, the concepts of security and us all
being in it together—a friendly community, as it were—had different
behaviors when a host is is $10-30 micro and wireless Interconnect can
slimed at Starbucks for free.
