describe MidasPlus, an interactive system used to study
three dimensional macromolecular structures. It will
illustrate the various ways molecular data can be
visualized and manipulated. The techniques include
atomic coordinate data, controls for rotations and
translations, depth-cued wireframe images, a variety of
surface forms, stereo view and kinetic depth effects, and
color encoded quantitative information.

Daniel V. Klein, LoneWolf Systems
Well defined languages for describing pictures have been
around since at least the 11th century. This talk
describes the progression of drawing languages starting
with Blazon (a heraldic language) through modern-day
Postscript, with digressions into similar languages for
knitting and weaving, cattle brands, hieroglyphics, and
the numerous encodings that have evolved over the
centuries. This is both a technical and a "fun" talk.

Invited Talk: A History of UNIX
Greg Rose, Australian Computing & Communications
Institute
The consistent exponential growth in the popularity of
UNIX systems means that the average user knows little
of its actual history. Much of the UNIX operating system
has its roots either in the evolutionary process leading
to the current versions, or in the political environment
prevailing while that evolution was happening. By
exploring the history of this development, a number of
otherwise obscure things about UNIX become much
clearer.
1:30 pm - 2:50 pm [track 3]
Invited Talk: The Odin System
Geoff Clemm, Bellcore
This talk will introduce Odin. Odin is a replacement for
Make. It is simpler, faster, and more powerful than Make,
especially for large, complex projects. Specific
differences between Odin and Make include: dependency
computation, validity of derived objects, disk space
useage, file variants, and file sharing.

Invited Talk: MIME & Metamail: Moving Multimedia Mail
into the Mainstream?
Nathaniel S. Borenstein, Bellcore
Most users continue to live in a text-only world, at least
for email. MIME (Multipurpose Internet Mail Extensions)
provides a standard format for multimedia electronic
mail. Early MIME implementations effect a transition
from text to multimedia, but the overall task is
enormous - requiring nothing less than the replacement
of ASCII as the "common denominator." This talk
provides an overview of MIME, then describes current
MIME implementations and the remaining obstacles that
separate us from the dream of universal multimedia
communication.

1:30 pm - 2:50 pm [track 3]
Invited Talk: Object Databases: More Than a Shift in
Modeling Paradigm
David J. Jordan, AT&T Bell Laboratories
Migrating from relational to object database technology
involves more than just applying the object paradigm to
conceptual database schema design. A key factor is the
choice of language used for specifying object semantics,
and where the resulting functionality executes - in the
client applications or database server - potentially
yielding database transparency and reduced application
development costs. The presentation will provide a
conceptual overview of object databases and how they
differ from current relational technology so one can
better determine which technology is more appropriate
for a particular application.
2:50 pm - 4:00 pm
