Fifth Annual International ColoradOS/2 Software Developers Conference

by Wayne Kovsky (Last updated December 25, 1996)



The Fifth Annual International ColoradOS/2 Software Developers Conference, the only OS/2-only, programmers-only conference in the world, was held the week of October 13 through 18, 1996, at Keystone Resort in Keystone, Colorado.

We had another super conference - it was great to see our old friends and to meet the many people new to ColoradOS/2 this year! Thank you all for coming and sharing your ideas, knowledge, and enthusiasm with the ever-growing ColoradOS/2 family.

About ColoradOS/2
In October of 1996, for the fifth consecutive year, an elite group of programmers, analysts, architects and innovators from around the world will gather in the Colorado Rocky Mountains to discuss, debate and challenge their software development platform of choice: OS/2.

As these professionals emerge from ColoradOS/2, putting their new insights and knowledge to work, they are poised to shape yet another generation of OS/2 software development.
 * The result? A metamorphosis.

Recognized worldwide for professional quality and value, ColoradOS/2 is characterized by its enriching, highly charged atmosphere of information exchange. Learning takes place with a no-holds-barred attitude. You'll see OS/2 from all sides, learning firsthand how to navigate through its challenges to produce exceptional results.
 * ColoradOS/2 is about answers.

ColoradOS/2 is synonymous with quality: we've gone to great lengths to design a program that would be the dream conference of any serious OS/2 programmer:
 * The best of the best.

a full-range of OS/2 software development topics a faculty of movers, shakers and problem-solvers flexible, self-mapped scheduling the inspiring grandeur of the Colorado Rocky Mountains Our goal is to promote and enhance the use of OS/2. Through our comprehensive program, support materials, speakers, venue and the attendees who return year after year, we strive to bring together the best of the best for an unparalleled experience. A word about our faculty. Our "faculty" is comprised of more than 45 OS/2 experts: people who were instrumental in the design and implementation of the OS/2 platform; people who have created substantial system architectures based on OS/2; people who know OS/2 inside out, upside down, backwards and forwards. Like you, all of these people live and work in the trenches with OS/2. They know what you're wrestling with, they know where you're coming from. Most of all, they are eager to share their knowledge with you.

Perhaps the best way to describe ColoradOS/2 is a "smorgasbord" -- as much as you want, of whatever you want, whenever you want it! From 8:00 a.m. to 9:00 p.m. (and typically beyond!) attendees roll up their sleeves to tackle the nuts and bolts of OS/2.
 * Conference Format

This year, we are pleased to have as our keynote speaker John W. Thompson, General Manager of IBM's Personal Software Products Division. Additional featured speakers include John Soyring, Vice President, Personal Software Products at IBM, and Joel Krautheim, President and co-founder of SPG Inc.
 * Featured Speakers

Our tutorial roster includes over 75 unique OS/2 related topics, each one offered three to five times throughout the week.
 * Tutorials

One very distinctive feature of ColoradOS/2 is self-mapped scheduling, permitting you to optimize your own personal schedule. Self-mapping allows individuals to achieve their goals for ColoradOS/2 at a reasonable pace across the span of five days. Advanced sign-up for tutorials is neither necessary nor available prior to your arrival at the conference.
 * Self-mapped Schedule

At most major conferences it can be difficult to interact with speakers or instructors; often they are available only during their appointed time for presentation. At ColoradOS/2, our speakers typically attend the entire conference, making themselves available throughout the week to participants.
 * Human Interface

Because we offer far more presentations than any single individual could attend, we make materials from every presentation available. A notebook containing a copy of the tutorial presentations is provided at registration to assist your schedule mapping. Each attendee receives a CD-ROM version of presentations and source code following the conference.
 * Documentation

Welcome Reception
Sunday evening we will be hosting a Welcome Reception from 7:00 to 9:00 p.m. This is a great opportunity to meet our speakers, find old friends and get to know new ones. If members of your family have accompanied you to Colorado, you are welcome to bring them along; we'd love to meet them too! The food is great, and you'll be among people just like yourself, OS/2's biggest fans (and some lovable geeks and geekstresses).

Schedule of Conference Sessions
Following is the schedule of the conference sessions for Monday through Friday. We begin each day with a Continental breakfast at 7:00 a.m., followed by a featured speaker at 8:00 a.m. The remainder of each day is divided into a series of 90-minute sessions, during which there will be nine tutorial topics running concurrently. Within each tutorial time period we have listed each speaker alphabetically and the topic that speaker will present. The last column (example: "1 of 3") indicates whether this represents the first, second, etc. occurrence of this particular topic and how many times it is being repeated during the week.

The days are both long and full, with presentations scheduled from 8:00 a.m. to 9:30 p.m., and yet people always want more, More, More!!! We have had many comments that having to go to lunch is too great a sacrifice, taking precious time away from at least one of the sessions that our attendees want to see. Therefore, in an effort to accommodate the requests for more, More, More!!!, we will be providing box lunches this year. No one should have to miss a single session merely to sustain life. The conference will end on Friday after lunch at about 2:00 p.m.

Schedule Cross-Referenced by Speaker
In addition to the above schedules which are organized by date and time, we have also cross-referenced the schedule by speaker and topic.

Real-Time Support from the VisualAge C++ Team
The VisualAge C++ Service and Support Team will be here this year operating a walk-in technical support center. The team will be available throughout the week for demos, consultations, trouble-shooting, and just plain old talking about VisualAge C++.

Indelible Blue
Indelible Blue, an exclusive dealer of OS/2 software, will be on hand during the week with software available for purchase. If you order software during the conference, you can receive your purchase at the conference or have it shipped direct to your home.

A Look at OS/2's Hooks - Robert Mahoney (2Rud Software)
Ever wonder how hot-key-activated or key-stroke recorder programs work? They use hooks as a means to examine and/or act upon messages or events, intercepting them before an application receives them. Robert will teach you how to create programs that use hooks, and he will illustrate some uses for hooks. Sample source code that will demonstrate the usage of hooks (along with some undocumented features) will be provided on the ColoradOS/2 CD-ROM.

Adding Sound to Your OS/2 PM Application with MMPM - Robert Mahoney (2Rud Software)
Want to jazz up your application? Add sound to it! This session will teach you how to add sound to your PM application, using the OS/2 MMPM interface. Robert will lead you through an exploration of the MciPlay functions, the Mci string interface and Playlists. Sample source code for each of the methods will be provided on the ColoradOS/2 CD-ROM.

Developing Portable User Interfaces with VisualAge for C++ - Hiroshi Tsuji (IBM RTP)
IBM VisualAge for C++ allows you to develop applications for both the OS/2 and Windows platforms. The user interface classes of the Open Class Library enable you to write a modern GUI for both environments. In this tutorial, Hiroshi demonstrates techniques that can make writing a portable GUI easier, along the way pointing out techniques to avoid. Some of the topics he will cover include the trade-offs of using PM-compatible controls on Windows, coping with different coordinate systems, platform-specific resource files, and detecting non-portable code.

Advanced Use of Canvas Classes - Hiroshi Tsuji (IBM RTP)
The Open Class Library of VisualAge for C++ provides canvas classes for creating and managing complex layouts of controls. In this session Hiroshi guides you on a detailed tour of these classes while detailing the supporting architecture that can be found in the IWindow hierarchy. Topics include: working with multicell canvases, minimum sizes and caching minimum sizes, the IWindow::setLayoutDistorted function, combining canvases, performance considerations, and a peek at future enhancements.

Introduction to Visual Programming with IBM's VisualAge C++ - George DeCandio (IBM RTP)
The Visual Builder is one of the most powerful components of IBM's VisualAge C++ product. In this session, George will introduce the concepts of visual programming and program construction from parts, showing how the Visual Builder can be used to create sophisticated Presentation Manager applications. George will incorporate into his presentation a live demonstration of the Visual Builder in which a "real" application will be constructed from the ground up. Creating this application will demonstrate the power of the Visual Builder, and it will also showcase the newest features of VisualAge C++'s Open Class library. No prior experience with Visual Builder is required for this session.

Advanced Visual Programming with IBM's VisualAge C++ - George DeCandio (IBM RTP)
A follow-on to the introductory tutorial, this session covers some advanced topics and programming techniques within VisualAge C++'s Visual Builder. George will describe how and when to use factories, variables and feature promotion, and he will demonstrate all of these concepts with live demonstrations and examples. Along the way he will provide many helpful tips and techniques, and he will preview some upcoming Visual Builder features. This session assumes attendees have some prior knowledge of or experience with Visual Builder, or that they have attended George's "Introduction to Visual Programming with IBM's VisualAge C++" session.

An Introduction to Java Technology on OS/2 Warp - Mike Cowlishaw (IBM Hursley)
Java(TM) is a platform-independent programming language and run-time environment that is one of the hottest technologies for the Internet today. In this session Mike will introduce the Java programming language and its supporting environment (including a discussion of the security and performance issues raised by Java), and he will review Java's use within the World-Wide Web. After this introduction, Mike will describe the IBM port of Java to OS/2 Warp, and he will then share some new ideas on Rexx and Java.

NetRexx: A New Language for the Java Environment - Mike Cowlishaw (IBM Hursley)
This session will cover the details of a new programming language, called NetRexx, which combines the strengths of both Rexx and Java. This new language is as readable and as easy to use as Rexx, yet it can be used both to write and to make full use of Java classes. Initial measurements suggest that the NetRexx source for a typical class has approximately 35% fewer lexical tokens and requires 20% fewer keystrokes than the equivalent class in Java. This session assumes some knowledge of Rexx, and a knowledge of Java to the level covered in Mike's session "An Introduction to Java Technology on OS/2 Warp".

A Technical Comparison of OS/2 Warp and Windows NT - Paul Giangarra (IBM Austin)
Throughout 1993 and into 1994, the computer trade press was predicting that Windows NT would dominate the office desktop; then Windows NT shipped. Throughout 1994 and 1995, the computer trade press was predicting that Windows 95 would dominate the office desktop; then Windows 95 shipped. Now the trade press is again predicting that Windows NT will dominate the office desktop, and some companies are switching to NT with no more rational basis than those predictions. Paul will begin with a tutorial of the technical differences between NT and OS/2, addressing both workstation and server platforms. If there are specific topics/questions that you would like Paul to cover in this introductory tutorial, send them to ppgx@austin.ibm.com. The remainder of the session will be a Q&A session focused on these two Operating Systems.

Using Speech Effectively as a User Interface - Paul Giangarra (IBM Austin)
Merlin, the next version of OS/2, will include the most advanced speech capabilities yet shipped in the industry. In addition to continuous speech navigation, the discrete speech dictation works amazingly well without the need for training the system to each user's voice. Adding voice capabilities to an application requires technical programming know-how (the focus of Bill Schindler's "Using VoiceType with OS/2 Warp (and Merlin)" session), but it also requires a thorough understanding of voice technology. In this tutorial, Paul will focus on integrating voice support into the user experience of an application and the facilities that the speech-enabled application opens up to its users.

Introduction to Distributed Object Programming - Roger Sessions (ObjectWatch, Inc.)
Why are businesses so interested in distributed objects? Roger demonstrates the importance of distributed objects as he introduces the basic concepts of OO programming (inheritance, encapsulation, and polymorphism). He shows how objects are distributed across networks and discusses some basic frameworks used to coordinate distributed objects. This is an introductory overview, designed for programmers who have no experience in OO programming.

CORBA Programming with SOM 3.0 - Roger Sessions (ObjectWatch, Inc.)
This tutorial is designed for experienced OO programmers who want to learn how to do distributed OO programming ala CORBA. Roger will guide you through an examination of interface definitions in IDL, object implementations in languages with CORBA bindings, and the various CORBA services used to coordinate distributed objects. Although the medium is SOM 3.0, the focus is more general.

The CORBA Persistence Services - Roger Sessions (ObjectWatch, Inc.)
It's time to throw away your OO database! We will examine in detail the CORBA services related to Persistence. The Externalization Service allows objects to export their state; the Persistence Service allows that state to be stored into any compliant database; and the Transaction service allows persistence to be coordinated with the overall transactions in which objects participate. Together, these three services allow distributed CORBA objects to support a variety of styles of Object Persistence, and to be stored in formats ranging from optimized object dumps to formats compatible with existing legacy data.

Workplace Shell Programmer's Roadmap (with Tips to Stay on the Straight and Narrow) - Greg Czaja (DevTech)
If you are new to Workplace Shell programming, you could not ask for a more qualified guide than Greg Czaja, author of DeskMan/2. In this session, Greg will introduce you to Workplace Shell programming, teaching you the skills you need to be able to return home and write WPS objects that both present and manipulate data. Instead of a broad survey of Workplace Shell programming, Greg will begin with a simple template for writing many Workplace Shell objects, focusing on what you really need to know to get started with Workplace Shell programming. You've probably heard that WPS programming is hard; Greg will show you how easy it can be.

Cracking the (Workplace) Shell - Greg Czaja (DevTech)
Workplace Shell programs are usually implemented via SOM programming, but Greg will demonstrate that there is Another Way. In this session, Greg will show you how to create an IPC mechanism that allows non-SOM applications (e.g., C, C++, Rexx, etc.) to interface with the Workplace Shell via standard calling conventions. Greg will also explore certain myths and truths about the Workplace Shell that will be of value to all OS/2 programmers. Sample source code will be provided on the ColoradOS/2 CD-ROM.

Object Oriented Component Development with OpenDoc - Joseph McIntyre (IBM Austin)
Learn how OpenDoc can evolve your application development environment to benefit from object oriented advantages, including OO development techniques, application packaging and the use of frameworks. During this session Joseph will illustrate techniques for developing object oriented components, including using and extending the PartMeister tool, subclassing components, and designing and building a framework.

Cross-platform Application Development Using OpenDoc - Joseph McIntyre (IBM Austin)
The compelling promise of cross-platform technology is the ability to develop components on one platform and then merely recompile those components for use on other platforms. This session will show you how to use OpenDoc and related technologies, including IBM OpenClass, to build components on OS/2 and deliver them on multiple platforms.

Design for Testing - Charlie Parker (IBM Hawthorne)
Thinking of testing only after we design and code, and then relying heavily on debuggers, may have been adequate for yesterday's small console programs, but it is reckless for applications today. Programming "in the large", especially complex GUIs and multi-threaded applications, poses special problems. Some modules may become too large for debuggers; we are likely to require problem information from users and beta testers who cannot run debuggers for us; and some problems appear only intermittently. One solution is to consider the testing and debugging problem during design, and to build the appropriate facilities into our application. This tutorial will give you some techniques we've found very useful while developing IBM AntiVirus, a product that bumps into every conceivable machine configuration and anomaly.

Designing and Developing Cross-Platform Code for 32-Bit Operating Systems (OS/2, Windows NT, and Windows 95) - Rhonda Rosenbaum (IBM Hawthorne)
Anyone who thinks multi-platform programming is fairly easy with today's tools probably isn't thinking about GUI applications. Rhonda's work on the design and development of the user interface for the cross-platform IBM AntiVirus gives her a real-world perspective that she will share with you in this tutorial. She will describe developing GUI applications for multiple platforms, keeping about 70 percent of the user interface source common across all platform. Topics include how to use C++ with multiple inheritance, use of collection classes and common service functions. Attendees should be familiar with C++ programming.

Developing Applications in VisualAge for Smalltalk - Greg Hutchinson (Attractors Consulting Inc.)
The Visual Programming era has arrived! How will it impact you and the way you program? VisualAge for Smalltalk is a solid development environment that combines the best of a visual development paradigm with a robust Object Oriented tool set. The result is a truly productive environment that can produce workable industrial strength applications. However, the visual environment presents some interesting new problems that the application developer must consider. What should (and should not) be created visually? Can a full functioning visual program be read? What design and coding techniques need to be followed? Are there performance penalties? When and what should you think about for packaging your application? In general, what are the issues that one must now think about when designing applications in VisualAge for Smalltalk? Greg will answer these questions by creating and discussing several working examples taken from real applications created in VisualAge for Smalltalk.

Java Jumpstart - Introduction to Java - David Moskowitz (Productivity Solutions)
You've heard about Java - the platform-neutral way to create Web pages that are dynamic and interactive rather than static and passive. Let David give you a jump start toward writing Java appletts. Intended for people with no Java programming experience, this session will introduce you to the basics of writing Java code and put you on the fast track for writing Java applets.

Developing Java Applications - David Moskowitz (Productivity Solutions)
This session is designed to be an extension of the "Java Jumpstart" tutorial and therefore assumes familiarity with the Java language.

It covers the myths and realities of consulting (whether for yourself or someone else).

OS/2 Warp Unleashed (Updated for Merlin) - David Moskowitz (Productivity Solutions)
This session is intended for anyone running OS/2. It covers the tricks and tips that will help save time and improve productivity using our favorite operating system. It will also highlight common problems and show how to avoid them.

So You Want To Be an Author - David Moskowitz (Productivity Solutions)
At ColoradOS/2 in 1993, Steve Mastrianni and David were literally surrounded by conference participants as they led an impromptu discussion of what it takes to be a successful author specializing in OS/2. This proved to be so popular that they agreed to repeat it as a planned seminar in 1994, then again in 1995, and David will do it again in 1996. Drawing on his own experiences as a successful author and magazine columnist, he offers some very practical advice about how to get started, what to expect, working with publishers and editors, etc. This is a rare opportunity to learn from a well-known author who has "been there, done that".

The State of the OS/2 Marketplace - David Moskowitz (Productivity Solutions)
OS/2 isn't dead!! - but, what is the real state of OS/2 development, the marketplace and the channel? This session provides up to the minute information, from independent sources, that can help you understand the OS/2 marketplace.

RTMIDI, the OS/2 Real-Time MIDI Subsystem - Timur Tabi (IBM Austin)
The OS/2 real-time MIDI subsystem (RTMIDI) provides real-time playback, recording, and processing of MIDI events. Using an object oriented paradigm, an application can not only play and record MIDI data with millisecond accuracy, but it can also configure the subsystem to handle all of its real-time processing needs. With RTMIDI, OS/2 provides MIDI support superior to Windows. This tutorial describes the architecture of RTMIDI and shows how to develop applications and device drivers to take advantage of all of RTMIDI's capabilities.

Developing Object Oriented OS/2 Device Drivers in C++ - Timur Tabi (IBM Austin)
Object oriented programming techniques are not just for application developers any more - you can use them in your OS/2 device drivers as well.

The issues involved include: Windows APIs vs. OS/2 APIs vs. the Developer's API Extensions (DAPIE); MFC vs. Open Class; OLE vs. OpenDoc; Multimedia; Visual C++ vs. VisualAge C++ (for both OS/2 and Windows); and the OS/2 Visual Builder. Particular emphasis will be placed on designing applications for portability from the beginning.

Direct-to-SOM Programming with VisualAge C++ - Joel Troster (IBM Canada Lab)
The VisualAge C++ products for both OS/2 and 32-bit Windows have a feature called "Direct to SOM" (DTS) that allows a programmer to develop SOM Objects and use them as ordinary C++ objects. DTS hides a lot of the details of SOM under the covers and allows your C++ SOM code to look like ordinary C++ code. In this tutorial Joel will introduce you to implementing objects and client programs using the DTS feature of VisualAge C++. He will demonstrate the power of DTS by first building a DTS Object and a batch client program to access it; next he will build a visual interface to the object using the VisualAge C++ Visual Builder; finally he will demonstrate how to distribute the object and access it using DSOM.

Distributed Applications Using NetFinity - Noel Bergman (DevTech)
NetFinity is the core of SystemView, IBM's standard framework for developing distributed system management applications, but NetFinity's use extends far beyond that genre. NetFinity provides a messaging layer and core set of services that are operating system independent. We will focus on building a new distributed application, illustrating how to build User Interface and Service components. We will show how NetFinity can connect the UI and Service components for the user, and how the UI component can use the NetFinity services to dynamically locate and connect with Service components. Sample source code will be provided on the ColoradOS/2 CD-ROM.

DSOM Objects for the Workplace Shell - Randall McClure (CyberWorks Corporation)
Here is a little-known secret: DSOM objects can provide the same look and feel as the WPS, without any of the programming headaches. By using DSOM objects to create WPS objects, programmers can remove the interdependencies between their application code and that of the Workplace Shell. Randall will show you how to use this technique, which also shifts the debugging environment from the WPS to a working environment that is much more manageable.

Lotus Notes APIs, Some C++ Wrapper Examples - Randall McClure (CyberWorks Corporation)
In this session, Randall will provide example C++ wrappers for selected Lotus Notes APIs, accompanied by a thorough discussion of the code. He will cover Notes initialization and database access in particular. Some knowledge of C++ is assumed.

Using the Rexx APIs to Extend Your Applications - Bryan Walker (Williams-Sonoma)
One of OS/2's many advantages is that it is not necessary to create your own macro/scripting language. Instead, Rexx can be used as the macro language for both new and existing applications, providing all the features desired of a macro language and more. This tutorial focuses on using Rexx as the scripting language of choice on OS/2, not on programming with Rexx. Bryan will familiarize you with the RexxStart API, Rexx function handlers, and the remaining tools from this rich set of functions. Learn firsthand how Bryan used the Rexx APIs to design a flexible, easily extendable, powerful yet small installation program.

Extended Attributes: Untangling the Interface - Bryan Walker (Williams-Sonoma)
The Extended Attributes API demystified: this tutorial details the workings of this very important but little understood and frequently avoided API, and additionally provides some functions that simplify its use. You'll learn why extended attributes are designed as they are and how their design relates to existing standards, a design that can help make your objects network ready.

HPFS Internals: An Introduction - Doug Azzarito (IBM Austin)
This session will take you through an introductory tour of the OS/2 High Performance File system (HPFS).

Introduction to OS/2 Multi-Threaded Programming - Kimberly Bobrow (Optimum Consulting, Inc.)
One of OS/2's most powerful capabilities for creating "Wow, I gotta have that!" programs is its preemptive multi-threading. Kimberly will present the "hows" and "whys" of skillful multi-threading, including the use of semaphores - which are vital for proper thread management. You will also learn how thread priorities can be used and how and when to adjust them. PM programs have certain special requirements when multi-threading, which Kimberly will also cover.

Introduction to OS/2 Inter-Process Communication - Kimberly Bobrow (Optimum Consulting, Inc.)
When writing programs for an operating system that can have multiple processes, you will inevitably need to communicate between processes. In this session we will discuss the various IPC mechanisms available in OS/2, including named and unnamed pipes, queues, shared memory and PM messaging.

Introduction to the IBM VisualAge C++ Open Class Collection Classes - Heinz Graalfs (IBM Germany)
The IBM OpenClass Collection Classes are designed to manipulate collections of objects in a group. Collections are used to store and manage elements (or objects) of a particular user-defined type. Each type of Collection has different internal structures and different access methods that are optimized for efficient storage and retrieval of objects of that type. This tutorial describes the types of Collections provided by the library, and introduces the classes that make up the Collection Class Library.

Introduction to the IBM VisualAge C++ Data Access Builder - Mike Polan (IBM Toronto)
Data Access Builder, a component of IBM's VisualAge C++ for OS/2, connects relational data with object oriented applications using a code generation tool and supporting services in a class library. Data Access Builder visually maps a relational table to an object oriented class, a column to an attribute and individual rows to an instance of that class. Code generated by the Data Access Builder can be used directly in C++ or IDL programs, or as parts in the Visual Builder.

Mike will show you how to use the Data Access Builder to generate code that is tailored to the database. He will construct a complete database application for retrieving, adding, updating and deleting data, using Data Access and the Visual Builder. He will demonstrate that you can do this without writing any code or even knowing SQL, while preserving the performance benefits of embedded SQL. Mike will show how Data Access Builder can be used to customize the mapping for additional flexibility in accessing the database, and discuss other relational to object oriented mapping issues. Functions and features of DABE (an early incremental beta of the next release) will be presented and demonstrated. Design direction for the next release will be discussed. Suggestions and feedback are encouraged.

Sample source code will be provided on the ColoradOS/2 CD-ROM.

OS/2 Exceptions, C Signals, and C++ Exceptions under VisualAge for C++ - Roger Pett (IBM Toronto)
Often the distinction between a merely good and a great program is in how well (or even whether) unexpected events are handled. In this tutorial, Roger will begin by describing the model that OS/2 uses to handle exceptions. Next he will cover the method whereby VisualAge C++ creates and handles C signals using this model, including the extensions to the ANSI C standard that permit use of signals in multi-threaded programs. Roger will also describe C++ exceptions, which are a different extension of the OS/2 Exception model. He will define and illustrate with examples the required coding techniques for all three exception handlers, discussing interactions between the handlers, and showing ways to use them together.

Snares and Snags in C/C++ Programming - Jim Gimpel (Gimpel Software)
Though efficient and powerful, the C/C++ language nonetheless offers numerous traps for the unwary. Perfectly legal and innocent looking code constructs can become debugging nightmares, or present unexpected portability or performance problems. The C++ enhancements to the C language have paved over some of C's programming potholes, only to have created new ones in the process. The sheer complexity of C++ only magnifies the problem. James will guide you through a number of specific coding examples that illustrate a variety of pitfalls, while suggesting some defensive strategies.

Using the Kernel Debugger - James Taylor (IBM Austin)
