Keynote Talk: Bits vs Atoms: Objects as Electronic Property
===========================================================

Brad Cox, GMU Pgm on Social and Organizational Learning

Objects are electronic property; a new form of goods composed of bits
instead of the atoms from which goods have been composed since
antiquity. But since bits are immune to the physical conservation laws
that have determined what it means to buy, to sell, or to own goods in
the past, this undercuts the incentives of those who would provide
them.

This simple but fundamental observation prevents us from evolving to
the advanced form of engineering that has been routine in other fields
since the industrial revolution. Until this problem is addressed,
software will remain a primitive craft instead of an advanced
manufacturing discipline. We'll have no other option but to fabricate
higher-level solutions from first principles instead of assembling
them from catalogs of well-tested prefabricated parts.

This problem has solutions. This presentation describes the one
advanced in Dr.  Cox's new book, "Taming the Electronic Frontier"
(Addison Wesley, 1995)


Dr. Cox is a faculty member of the George Mason Program on Social and
Organizational Learning. He is the author of Object-oriented
Programming, An Evolutionary Approach, a book that is generally
credited with launching today's industry-wide enthusiasm for
object-oriented technologies. He co-founded the Stepstone Corporation
and originated the Objective-C(tm) programming language and
Software-IC(tm) libraries to facilitate a software industrial
revolution where software would be produced, not by fabricating
everything from first principles as today, but by assembling
interchangeable (reusable) software components that are in turn
supplied by lower-level echelons of producers.

Dr. Cox recently founded the Coalition for Electronic Markets whose
objective is to build and deploy a nationwide revenue collection
infrastructure for commerce in electronic goods. Since electronic
goods are composed of intangible bits instead of the atoms of commerce
since antiquity, they can be copied by any customer without loss and
transported at literally the speed of light..

Prior to co-founding Stepstone, he worked for Schlumberger-Doll
Research where he applied artificial intelligence, object-oriented,
Unix, and workstation technologies to oil field wireline
services. Before that he worked in the Programming Technology Center
at ITT, where he applied Unix and object-oriented technologies in
support of the development of a large, highly distributed telephone
switching system, System 1240.

He received his Ph.D. from the University of Chicago for theoretical
and experimental work in neurophysiology in an area that has since
become known as neural networks. His post-graduate experimental
studies were at the National Institutes of Health and at the Woods
Hole Marine Biological Laboratories.



Experience Talk: SUN DOE Beta Evaluation and the ISI project
========================================================

Mathias Loepfe and Stefan Arn, Ad Novum

Ad Novum Informatik AG has been engaged in Sun Microsystems'
evaluation program of DOE (Distributed Objects Everywhere) since
November 1993. The project DOE is Sun's approach to the implementation
of a CORBA-compliant ORB.

Experience shows that software reuse can be put into practice by a
strong separation of interface and implementation. This decoupling
allows for language independence on both the client and the server
side and results in independent and reusable components. It also
provides a sensible migration path for embedding legacy applications
into modern client server environments.

However, distribution is still problematic. Apart from problems in the
area of name services, life cycle model, persistent objects, and
multi-ORB applications designer still have troubles with the
distinction between fine grained language objects and coarse grained
CORBA objects.

Moreover, a big disadvantage is the lack of language support for
distributed systems. Ordinary languages provide no constructs for
distributed systems, like "protocol", "service", or "transaction"
which would ease the development of such systems.

Mathias Loepfe has been with Ad Novum since 1989. He is designer and
project manager for distributed systems. Stefan Arn is founder and CEO
of Ad Novum. Both have been involved in object-oriented software
development in various industrial or banking related application
domains.



Tutorial: Building Distributed Applications with CORBA and C++
==============================================================

Steve Vinoski, HP

The Common Object Request Broker Architecture (CORBA) Specification,
published in 1991 by the Object Management Group (OMG), provides a
standard base on which distributed object computing systems and
applications can be built.  In late 1994 the OMG adopted a standard
C++ language mapping for the OMG Interface Definition Language (IDL)
and the standard CORBA interfaces.

This tutorial will show how CORBA applications can be written using
the standard OMG IDL C++ Language Mapping.  Examples will show how
basic IDL constructs such as interfaces, operations, object
references, and sequences can be used to describe and implement CORBA
objects, and how C++ applications request services from such
objects. After the basic IDL features have been covered, code samples
will show the Dynamic Invocation Interface (DII) can be used, and how
standard OMG Object Services (CORBAservices) such as Naming can be
used to support distributed applications.


Steve Vinoski is a software architect in Hewlett Packard's Chelmsford
System Software Laboratory (CSSL), where he has been a part of the HP
distributed object computing development team for over four
years. Together with Dr. Doug Schmidt he writes the "Object
Interconnections" column in C++ Report.  During 1994 he served as the
editor of the OMG IDL C++ Language Mapping Specification, and he
currently chairs the OMG C++ Mapping Revision Task Force.



Tutorial: Experiences in Developing Distributed Applications with CORBA
=======================================================================

Sean Baker, Iona

This Tutorial will present a practical view of CORBA as a set of
technologies for integrating heterogeneous environments. Examples of
large applications implemented with these technologies will be
presented. These case studies will be based on what has been achieved
with the ORBIX CORBA compliant distributed platform.

Dr. Sean Baker is Director of IONA Technologies. He has been one of
the designers and implementors of ORBIX, the platform commercialized
by IONA. Dr.  Sean Baker is involved as a consultant in several
developments of large distributed applications. He has been Professor
during 12 years at the Trinity College in Dublin. His main interests
are distributed systems, data bases and object oriented programming.



Location
========

Swiss Federal Institute of Technology, Lausanne (EPFL) Please look for
signposts to find the actual lecture hall ("amphi" CO2, in front of
cafeteria LA COUPOLE).

Directions for train travelers: when you arrive at the railway station
(Lausanne CFF), walk out in front of the station (Place de la Gare),
and cross to take the "Metro" to Lausanne-Centre (take a ticket at
2.-, it covers the whole trip to EPFL).  At Lausanne-Centre (also
called Flon), take the "Metro Ouest" (also called TSOL, runs every 10
minutes) to EPFL (about 13 minutes away).  At the metro station EPFL,
walk down (same direction as your metro is going) and turn left to get
under the street on the way to "La Coupole" (straight ahead).
