When you think of performance tuning, what comes to mind? Handcoding in assembly language? Profiling? Fancy data structures? How about a process called "deslugging" for tracking down correct, but slow, code. In addition, Mike Armistead discusses profiler evolution.

Heap errors are among the most frustrating programming bugs you'll run up against. Steve presents libraries for intercepting heap-related calls and generating message logs.
by Taed Nelson
Taed examines the problems arising from array-bounds violations--stack corruption, segmentation violations, and ultimately, programmer insanity. Although focusing on Purify 2.0, he also looks at Insight, Sentinel, MemCheck, and Bounds-Checker.

Rick's interrupt-monitoring program traps and logs interrupt activity, enabling your debugger or other program to gain control when specified interrupts occur.
by Roger Crooks
Designers of high-performance embedded systems look for performance gains wherever they can be found. Roger examines why debugging RISC-based systems is complex, especially when caches are involved.

This utility lets you chat interactively with other users across Novell networks. You can call other users, accept or reject incoming calls, and even set up a conference chat via individual-user viewports.

Optlink for Windows, a high-performance replacement for Microsoft's LINK.EXE and Borland's TLINK.EXE, provides optimizations that increase execution speed while reducing application size.
by Ray Valdes
Ray discusses the tools and techniques he uses when figuring out what went wrong with his Windows apps. Ivan Gerencir adds his multi-application message trace facility for Windows.

Michael puts forth this examination of why the Forth language is still a good choice for many applications, and how Forth relates to cellular automata, genetic algorithms, artificial life, and the game of Life.

Al unchains version 2.0 of is D-Flat++ library--a CUA-compliant library for DOS text mode implemented as a C++ class library. D-Flat++ applications run from a virtual desktop that contains a screen, a keyboard, a mouse, a clock, and a speaker, represented by classes in the library.

From the year 1661 to today, palindromes are tit-4-tat backwards and forwards. When examining Windows file structures recently, Tom discovered that palindromes are the bases of a data-encryption method.

This month, Pawel Szczerbina looks at undocumented aspects of Novell's NetWare Core Protocol (NCP). When examining the so-called "F2 interface," Pawel found hundreds of NCP functions, although Novell only documents the NCP Erase Files function.

Fuzzy logic is something to think about, and Bart Kosko's new book Fuzzy Thinking is a good place to start mulling it over.

Can we talk? Interoperability means that computer systems must be able to communicate with each other safely, efficiently, and securely. In December, we'll examine these issues--and more!
