Since copyright is automatic upon creation of a piece of work, surely it isn't
possible for anything to have "no copyright"? You don't have to register
anything to get copyright (like you do with a trademark); you don't need to
have any legal agreement to get copyright (like you do with a licence);
copyright simply exists as soon as something is created.
Therefore I don't think it's possible to avoid copyright existing on a created
piece of work. However, copyright is entirely different from the licence
under which something may be used / distributed, etc.
I agree with you completely that Open Source and Free Software are entirely
different from Public Domain software, however I think Tomer's original
statement about VirtualBox being out in the public domain (without the
capitals) is meaningful. It means something is readily available without
having to go to a specific source of supply.
And yes, the most important part of all this is that once something is
licensed under the GPL, it remains open for ever, including derived works.
Never automate fully anything that does not have a manual override capability.
Never design anything that cannot work under degraded conditions in emergency.
Please reply to the list;
