Dear Brian,

Russell Standish has a book summarising some stuff, also many references
at the end (will bring you up to speed on definitions like ASSA/RSSA):

http://www.hpcoders.com.au/nothing.html

(pdf on that site:http://www.hpcoders.com.au/theory-of-nothing.pdf)

Schmidhuber has interesting papers:
http://www.idsia.ch/~juergen/computeruniverse.html

And of course you will find many interesting stuff on Bruno's site (I
have yet to read most of it - Sane 2004 paper will start you on the
trip. ;-)

http://iridia.ulb.ac.be/~marchal/publications.html

Not widely discussed on this list but I think of interest is this topic:
http://digitalphysics.org/

And you know Tegmark, of course :-)

As for the archives - I think there is a wealth of information to be
mined there, but I also find this a pretty tedious way of getting at the
information.

There was an everything wiki once, I gather, why did the project die?
Would there be interest on the list in starting a collaboration to get a
wiki going and extract stuff from the archives?

Cheers,
GŁnther
