There are several ways in which the current axiom-developer.org
site is not "secure" - some of these ways are by design (because
it is intended to be an open interactive system) and some are
due to financial and resource constraints. I think that the
current situation amounts to an "acceptible risk", in that
sense. In my opinion in general, trying to control knowledge
is not the right way to manage risk. By now there are already
many thousands of people out there who could inflict damage
on this system if they wanted too. But I think that for the
forseeable future we can continue to promote an environment
where no one wants to do this. Perhaps I am naive?

You are right. But I think most Axiom developers do care
about how the project is managed and the tools that we
have available to help.

Actually Zope makes reconstructing pages VERY EASY. In the
Zope management interface there is an 'Undo' option for
each page. If you click 'Undo' you are presented with a
list of changes and checkboxes to indicate which changes
you want to reverse. Then all one needs to do is click
'Undo Selected Changes' and presto, the page is back to
the way it was.

Yes. Right now the tar gzip'd contents of the MathAction site
(not including the programs) is about 260 Mb. -a large download
over the Internet but not unmanagable. The problem is only that
we do not have another machine dedicated for the purpose and
we do not have any regular (automatic) procedures in place to

I think Tim is paying somewhere in the neighborhood of $80
per month of the current shared virtual server at RoseHosting.
I expect that for about $20 more, RoseHosting could probably
provide a reasonable regular backup service. But someone (Tim?)
will have to make inquirys about this.

One of the goals of the Axiom Foundation was also to support
the maintenance and operation of the axiom-developer web site.
The concept of a "bounty" for programmers just seemed like
a "sexy" idea that is working for some other open source
projects. But, sadly even though the access rate to the
MathAction website is now more than 2,000 users per month
and the Windows version of Axiom has been downloaded many
more thousands of times, we still do not seem to be able
to attract donations. The total collected so far is only

But then there were no users of the site, now there are
thousands of accesses per day. The original design was easy -
although at various times I did try to discuss it openly on
the Axiom Developer email list. (See email archives.)

I suppose ... but already I am involved in so many different
web sites that require login that I am not really able to
manage different user ids, passwords etc. I do end up using
the same id in most cases, so in the end it is just a hassle
and still not really secure. I expect many people are in the
Anyway, thanks to some new innovations of the people who
developed the ZWiki program on which MathAction is based,
we seem to have a new option to consider. It is now possible
to implement a mixed Wiki/Portal system that provides an
easily controllable range of user authentication and open
access. I have a test version of this system installed at
If you have some time and a machine that reliably accessed
the Internet, I would be very interested in your opinions
about this new approach.
