They are delivered by experts with hands-on experience. Attend these tutorials and benefit from the opportunity for in-depth exploration and skill development in essential areas of object-oriented technology. Seating in limited, so register now to guarantee your first choice. Tutorial fees include: * Admission to the tutorials you select * Lunch * Printed and bound tutorial materials from your sessions ==================== MONDAY, JUNE 17 ==================== M1am (9:00 am - 12:30 pm) Introduction to CORBA and CORBA Services Bruce Martin, SunSoft, Inc. Intended Audience: Developers who want an introduction to applying basic object-oriented techniques to distributed applications using CORBA technology. The Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA) defines a standard architecture for distributed object-oriented communication. This course will describe the CORBA technology. Topics will include: * the interface definition language * the object request broker * the interface repository Additionally, the CORBA Services standard defines a set of distributed object services that integrate distributed objects into distributed applications. CORBA Services to be covered include: * Events * Naming * Relationships * Life cycle * Transactions Use of the distributed object technology will be illustrated using a simple distributed stock-trading application. The application is constructed by integrating re-usable distributed objects using CORBA and CORBA Services technology. Dr. Bruce Martin is a senior staff engineer at SunSoft where he works on distributed object services and distributed application models for SunSoft's NEO system. He was the primary author of several of the OMG's CORBA Services specifications and has authored several papers in the areas of distributed object-oriented systems, interface languages, and transaction models. ==================== M2am (9:00 am - 12:30 pm) Java: A Language for Providing Content on the World Wide Web Jim Waldo, Sun Microsystems Labs and JavaSoft Intended Audience: Experienced programmers and technical contributors. Participants should be familiar with the C and C++ programming languages, the basics of object-oriented programming, and the basics of how the World Wide Web operates and is organized. The first part of this course will introduce Java, an object-oriented language designed to enable live content on the Internet. This "live content" consists of full programs that can be placed into HTML documents. When such a document is loaded into a Java-enabled HTML viewer such as HotJava, the program is run, creating a page with active or even interactive elements. While designed for creating interactive web content, Java is a general purpose, object-oriented language with such features as garbage collection, exceptions, strong typing, and a clean separation between classes and interfaces. Built around a C-style syntax, Java allows the writing of secure, robust programs that can be relied upon to run in a finite amount of space without crashing into a pile of bits. Language, as well as the set of class and interface libraries which are defined as part of any compliant Java implementation, will be discussed. How one uses Java to create "applets", programs that can be included as part of a standard HTML document, will be discussed, as well as how to write such applets, what resources are available to these applets, and what features of the language and runtime environment allow these applets to be run securely by anyone on the Internet. If time permits, the day will end in wild speculation and discussion of the possible technological and social impacts of the kind of computing that Java allows. After this course, attendees will understand the structure and features of Java and should be able to write programs in it. Attendees should understand how to write applets, how to include those applets in an HTML page, and understand the security features of the language and runtime environment that allow such applets to be run with confidence over the Internet. Jim Waldo is a senior staff engineer with Sun Microsystems Laboratories where he does research in the area of reliable distributed computing. A long-time advocate of object-oriented programming and the architect of one of the first distributed object request brokers, he has written and spoken extensively on object-oriented programming techniques, distributed computing concepts, and techniques for building robust, reusable software. ==================== M3am (9:00 am - 12:30 pm) New ANSI C++ Features Josee Lajoie, IBM Canada Laboratory Intended Audience: Individuals familiar with C++, but not with the C++ standards committee's work. The C++ draft standard is based on the C++ Annotated Reference Manual (ARM) by Margaret Ellis and Bjarne Stroustrup. The C++ standards committee has adopted two major language extensions that were not described in the ARM: namespaces and runtime type identification (RTTI). The committee also clarified the template chapter which appeared as a commentary chapter in the ARM. This course will introduce namespaces and RTTI language features, and present the clarifications affecting templates. Topics will include: o Namespaces -- Namespaces and class libraries *How are namespaces defined? *How do they resolve the global name space pollution problem? *How can they be used to package class libraries? -- Using directives and using declarations o Templates--An overview of the template compilation model -- Instantiations *How, when, and where do template instantiations take place? *How can users take control over the template instantiation mechanism if performance is a priority? --Template Specializations *How can users provide their own template specializations for template classes or functions? --Templates and Namespaces *How do template instantiations interact with namespaces? o RTTI -- The type_info class and the typeid operator *What functionality do they provide? *How are they used for object persistence? --The dynamic_cast operator * Why and how are they used for navigating class hierarchies? Josee Lajoie is a staff development analyst in the VisualAge C++ compiler group at IBM. She is vice-chair of the ANSI/ISO C++ standards committee and the chair of the Core Language Working Group for the committee. She writes the C++ Standard columns for C++ Report. ==================== M4pm (1:30 pm - 5:00 pm) Building Distributed Applications With CORBA and C++ Steve Vinoski, Hewlett-Packard Intended audience: Designers and implementors of distributed systems interested in developing CORBA-based applications in C++. Participants should be comfortable programming in C++, and have some knowledge of basic distributed computing issues. Attendees will benefit from the presentation of actual, working C++ code that illustrates how Object Request Brokers (ORBs) and CORBA services can be used to deploy working distributed systems. Version 2.0 of the Common Object Request Broker Architecture (CORBA) Specification provides a standard base on which distributed object computing systems and applications can be built. Part of CORBA 2.0 describes the C++ language mapping which details how applications can be developed and implemented using the Object Management Group (OMG) Interface Definition Language (IDL) and the standard CORBA interfaces with C++. This course will show how CORBA applications can be written using the standard OMG IDL C++ Language Mapping. In the first half, the basics of CORBA will be presented. Then, examples will show: * how IDL constructs (such as interfaces, operations, object references, and sequences) can be used to describe and implement CORBA objects, and * how C++ applications can use client-side stubs and the Dynamic Invocation Interface to request services from such objects. The second half will show how standard OMG CORBA services such as Naming, Events, and Lifecycle can be used to support distributed applications. Steve Vinoski is a software architect in Hewlett-Packard's Chelmsford System Software Laboratory. He is currently the technical leader for the development of HP ORB Plus 2.0, HP's CORBA-conformant ORB product. He chaired the OMG C++ Mapping Revision Task Force and currently represents Hewlett-Packard on the OMG Architectural Board. Together with Doug Schmidt he writes the "Object Interconnections" column for the C++ Report . ==================== M5pm (1:30 pm - 5:00 pm) Advanced Modeling and Design for Java Systems Desmond F. D'Souza and Petter Graff, Icon Computing, Inc. Intended audience: Attendees should be knowledgeable about object design and have some familiarity with Java. This course will present selected advanced modeling techniques that exploit Java as the implementation vehicle.

He is the author of the Education and Training column in the Journal of Object-Oriented Programming and in Report on Object Analysis and Design. Petter Graff is the director of technology and applications at ICON Computing. He has worked with object technology since 1989. Petter has presented tutorials on advanced modeling and design techniques at conferences, and has published articles on model integration. ==================== M6pm (1:30 pm - 5:00 pm) STL In Action Graham Glass, ObjectSpace, Inc. Intended audience: C++ programmers This course focuses on the new ANSI C++ Standard Template Library (STL), a set of reusable containers and algorithms. The STL design is different from that of traditional container libraries, and maintains a clean separation between algorithms and containers. This philosophy can be applied to many other library domains, and may change the way that C++ libraries are designed and implemented. STL users in the C++ community seem to enjoy their new-found power, but some programmers are concerned that STL can be accidentally misused and cannot be used effectively in a multi-threaded environment. The course addresses these issues and also shows how STL can be enhanced in a non-intrusive way. The course is comprised of the following sections: - the background, philosophy, and operation of STL - making STL easier to use - using STL in a multi-threaded environment - adding persistence to STL Graham Glass is the president and co-founder of ObjectSpace, Inc, specialists in object technology, where he heads up the product division. His goal is to predict the next paradigm shift and to create the technology that supports it. ==================== TUESDAY, JUNE 18 ==================== T1am (9:00 am - 12:30 pm) Java Applets and the AWT Nataraj Nagaratnam, Syracuse University Intended audience: Developers interested in developing interactive, animated GUI Java applications by exploiting the capabilities of the Java Abstract Window Toolkit (AWT). Participants should be familiar with Java. This course will describe the applet construction using the Java AWT.

The course assumes a working knowledge of C++. Network OLE (formerly known as Distributed COM or DCOM) is a lightweight object model that allows objects to be transparently distributed across heterogeneous platforms and networks. While the initial release is bundled with Windows NT, support for most major platforms, including most UNIX variants, is currently in development. This course gives a detailed look at the programming techniques used to implement COM objects that support transparent distribution and language-independent interoperability. The topics covered are: COM as a Binary Standard -Interfaces as binary firewalls -The C++ Binding for COM -IUnknown and the Laws of COM Packaging and Advertising COM Servers -Class Objects and Servers -The Service Control Manager (SCM) COM Interface Definition Language (IDL) -IDL Basics -Building type libraries using IDL Standard Marshaling Architecture -The Standard Marshaler -Building Proxy/Stub pairs in IDL Custom Marshaling -Marshaling via private subcontracts -Marshaling by value -Implementing Smart Proxies Network OLE Specifics -OXIDs/OIDs/IPIDs - Identifying Servers, Objects, and Interfaces -Object References on the Wire -OLE on UNIX COM Threading and Concurrency Models -Apartment Model Threading - Why and How -Freethreaded COM - Performance and Constraints Connection Points -Bi-directional Contracts -Exposing and discovering Outbound Interfaces Don Box has been working in networking and distributed object systems since 1989. He is currently chronicling the COM lifestyle in book form and writes a regular column on OLE in both the C++ Report and Microsoft Systems Journal. He is active as a consultant on COM-related projects and regularly gives seminars on OLE and COM. ==================== T3am (9:00 am - 12:30 pm) Pattern-Oriented Software Architecture Hans Rohnert, Siemens AG Intended Audience: Software developers and technical managers. The level of this course is intermediate to advanced; no previous exposure to patterns is necessary. A pattern gives a solution schema to a recurring design problem in software development. While patterns have been gaining considerable attention during the last few years, previous efforts concentrated on low-level patterns (idioms) and mid-level patterns (design patterns). The course will discuss patterns at the level of overall software architectures. It will present a system of patterns for software architecture that combines the high level patterns with an enriched set of lower-level patterns, and organizes them into a cross-referenced catalog. The course will provide in-depth explanation of the notion of patterns, presenting several patterns at different levels of granularity. Example patterns are: *Broker *Layers *Blackboard, *Model-View-Controller *Publisher-Subscriber *Client-Dispatcher-Server *Counted Pointer Participants will be provided with preprints of full pattern descriptions using a system of interrelated patterns in a practical example. Dr. Hans Rohnert works for the Siemens Corporate R&D labs in Munich, Germany. He is co-author of an upcoming book, Pattern-Oriented Software-Architecture - A System of Patterns. He studied at the University of Saarland and the International Computer Science Institute at UC Berkeley. His research interests include patterns, object-oriented programming, combinatorial algorithms, and data structures. ==================== T4pm (1:30 pm - 5:00 pm) Inter-Domain Management: CORBA, OSI, SNMP Subrata Mazumdar, Bell Laboratories, Lucent Technologies Intended Audience: System analysts, architects, and programmers involved in management of networks, systems, and services. Participants should know either CMIP or SNMP. Knowledge about CORBA architecture and OMG Interface Definition Language (IDL) will be helpful. After this course, participants will be able to apply CORBA and object services for network and system management applications. This course is based on current draft specification of Joint Inter-Domain Management Task Force (XoJIDM) sponspored by X/Open and Network Management Forum. The Inter-Domain Management specification is divided into two parts: specification translation and interaction translation. This course will cover: --Overview and Status of XoJIDM Activities --Overview of CORBA and IDL --Issues in Inter-Domain Management -- Specification Translation Schemes o Mapping of ASN.1 Types to CORBA-IDL Types o Mapping of GDMO Templates to CORBA-IDL Interfaces and Operations o Mapping of SNMPv2 MIB to CORBA-IDL Types and Interfaces --Issues related to Interaction Translation in OSI System Management o Mapping of Names o Mapping of LifeCycle Service o Mapping of Events and support for Filtering --Gateway between ORB and CMIP/SNMP network Management Agent --Summary and Discussion After this course, participants will be able to apply CORBA and object services for network and system management applications. Subrata Mazumdar currently works at Bell Laboratories, Lucent Techonologies. Previously, he was with IBM T.J. Watson Research Center where he developed the architecture and prototype of a protocol-independent network management agent, a CORBA-based OSI system management agent, and designed and implemented the prototype of a CORBA-based TINA-C Distributed Processing Environment for multi-media services. ==================== T5pm (1:30 pm - 5:00 pm) Introduction to the Python Programming Language Jim Fulton, Consultant Intended Audience: Participants with some programming experience who would benefit from a powerful, easy-to-use, very high level object-oriented programming language. Python is an interpreted high level object-oriented programming language, combining remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. A large collection of existing modules is available for system programming, GUI development, database management, scientific computing, building WWW applications, distributed computing, and more. New modules are easily written in Python, C, C++, or other languages that can interface with C. Python may also be used as an extension language for applications that need a programmable interface. Python is highly portable: it runs on UNIX, DOS, Windows, Macintosh, OS/2, Amiga, and other platforms. This course will provide a basic introduction to Python, including: o Python Basics - Using the Python interpreter interactively, - Python expressions and control statements, - Using Python modules and high-level data types, - Creating Python scripts, - Standard Python object protocols, - Writing Python functions, - Creating Python Modules, - Using documentation strings to make objects self-documenting, - Overview of pre-existing modules o Object-Oriented Programming in Python - Class definition, - Special methods for implementing standard protocols: o Numeric types, o Sequence types, o Mapping types, o Callable objects, o Overriding standard method attribute lookup, - Overview of defining new object types using C or C++ extension modules. Jim Fulton is a consultant and software engineer with several years experience building systems using a variety of object-oriented languages. He has served on the ANSI Smalltalk committee and is currently a member of the Python Software Activity steering committee. Mr. Fulton holds a BS and MS from Case Western Reserve University, and an MS from George Mason University. ==================== T6pm (1:30 pm - 5:00 pm) OO Design Patterns for Concurrent, Parallel, and Distributed Systems Douglas C. Schmidt, Washington University, Missouri Intended audience: Software developers familiar with general object-oriented design and programming techniques (design patterns, modularity, and information hiding), fundamental OO programming language features (classes, inheritance, dynamic binding, and parameterized types), basic systems programming concepts (process/thread management, synchronization, and interprocess communication), and networking terminology (client/server architectures and TCP/IP). This course examines and evaluates a suite of OO design patterns that help to alleviate the complexity of developing concurrrent, parallel, and distributed object-oriented software. These patterns (and the framework components that implement them) have been used successfully on major OO communication software projects to build telecommunication switch management applications, network management for large-scale global personal communication systems, and electronic medical imaging systems. The course illustrates by example how to significantly simplify and enhance the development of software that effectively utilizes concurrency and network services via the use of: * Object-oriented design techniques - design patterns, layered modularity, and information hiding * C++ language features - abstract classes, inheritance, dynamic binding, and parameterized types * Tools - object-oriented communication frameworks (such as ACE) and object request brokers (ORBs) * Advanced operating system mechanisms - event demultiplexing, multi-threading, multi-processing, and explicit dynamic linking * Emerging standards for distributed object computing - OMG CORBA and Network OLE/COM The course examines patterns and C++ code abstracted from production distributed electronic medical imaging and telecommunication systems to illustrate key points in the examples. Doug Schmidt is an assistant professor of Computer Science at Washington University in St. Louis, Missouri. His research focuses on design patterns, implementation, and experimental analysis of object-oriented techniques for developing high-performance, distributed communication systems on parallel processing platforms that run over high-speed networks.

USENIX is well known for its technical conferences, tutorial programs, and the wide variety of publications it has sponsored over the years. USENIX is the original, not-for-profit membership organization for individuals and institutions interested in UNIX and related technologies. Evolving with technology, USENIX has broadened its activities to include open systems and the globally interconnected and interoperable computing environment. The USENIX Association and its members are dedicated to: * problem-solving with a practical bias, * fostering innovation and research that works, * rapidly communicating the results of both research and innovation, and * providing a neutral forum for the exercise of critical thought and the airing of technical issues. ============================cut here============================ ************************************************************************ REGISTRATION FORM 2nd Conference on Object-Oriented Technologies (COOTS) June 17-21, 1996 Toronto, Ontario, Canada ************************************************************************ Please complete the form below and return with full payment to: USENIX Conference Office 22672 Lambert St., Suite 613, Lake Forest, CA 92630 Phone: 714.588.8649 / Fax: 714.588.9706 Email: conference@usenix.org Office Hours: 8:30am - 5:00pm Pacific Time NAME________________________________________________________________ (first) (last) FIRST NAME FOR BADGE____________________________Member Number_______ COMPANY OR INSTITUTION______________________________________________ MAILING ADDRESS_____________________________________________________ (mail stop) ____________________________________________________________________ CITY___________________________STATE____ZIP___________COUNTRY________ TELEPHONE NO:_________________________FAX NO._________________________ NETWORK ADDRESS______________________________________________________ (one only please) The address you provide will be used for all future USENIX mailings unless you notify us in writing.
