RE: Time to get serious

Nowadays people look at the JVM like its some sort of magic kingdom where
the laws of physics no longer apply, but the truth is it's just more code.

I'm going to steal this quote, use it as my own and only give Joe credit
when Joe catches me using it (only kidding). I think this should become the
battle cry of the IT community. I also think we should point out the same
thing about MSSQL, .NET, Oracle and all of the others who make the general
public into testing environments rather than properly testing their
applications and products.

This is in fact how all OO languages actually do it, and how we did it
back in the pre-OO days.  We wrote object-based applications in C back
in the 80s, and to do it we created "handles", which were nothing more
than VOID pointers.  The calling program had no idea what the pointer
pointed to, but the called procedure used it as a pointer to the
structure which held the "instance data" for the "object".

None of this is exactly rocket science and back in the old days a decent
CS teacher would explain that to you.  Nowadays people look at the JVM
like its some sort of magic kingdom where the laws of physics no longer
apply, but the truth is it's just more code.
