DATE COMPRESSION AND YEAR 2000 CHALLENGES
by Robert L. Moore and D. Gregory Foley
Ultimately, fixing Y2K problems is about fixing storage overflow, and there are a variety of solutions that address the problem. Bob and Greg examine some of these solutions, focusing on date compression.
STRATEGIES FORSOLVING THEY2K PROBLEM
by William Gothard and Les Rodner
Even though Y2K solutions are fairly straightforward, the Year 2000 crisis still is a bet-your-business problem. Our authors describe the analysis, conversion, and testing process.
A YEAR 2000 TOOL SUITE
by Dev Bhattacharyya
Dev presents a Year 2000 toolset written in Java, consisting of a scanning tool that examines source code for date-related areas, and a data ager tool that lets you manipulate existing production data.
HDF: THE HIERARCHICAL DATA FORMAT
by Brand Fortner
The Hierarchical Data Format, developed at the National Center for Supercomputing Applications, is a portable, self-describing data format for moving and sharing scientific data in networked, heterogeneous computing environments.
ALGORITHMS FOR HIGH-PRECISION FINITE DIFFERENCES
by Michael Herstine
Michael presents algorithms that help you improve numerical methods in situations where obtaining greater accuracy from the function evaluations is difficult or impossible.
THE PENTIUM F00F BUG
by Robert R. Collins
When x86 processors encounter an invalid instruction, the processor is supposed to generate an invalid opcode exception. If this mechanism fails, however, the program can bring the system down -- and that's what happens with the F00F bug.
EXTENDING WINDOWS CE 2.0 MFC DATABASE CLASSES
by John C. Schettino, Jr.
John presents a set of Windows CE database classes and subclasses of the 2.0 MFC classes that provide an object-oriented wrapper to the basic database search API.
CUSTOMIZING DDX/DDV
by Jean-Denis Bertron
Jean-Denis implements a system for customizing data exchange routines to add macro processing to Windows.
FAST MEMORY ALLOCATION
by H. Thomas Richter
In embedded-controller projects with execution time constraints, it's okay to sacrifice memory for speed. The power-of-two Fast Memory Allocator (FMA) Thomas presents here is used in just such a project.
ACTIVE DATA OBJECTS & ASP
by Mark Betz
Active Server Pages are useful for generating output and managing application state on behalf of a client. When combined with Active Data Objects, your scripts can manipulate ODBC data sources to do nearly anything that is possible in native SQL.
THE HOT VIEWS GRAPHICS LIBRARY
by David P. Heddle
The Hot Views (Hv) graphical user-interface library was designed for use in scientific modeling and simulation applications.
PROFILE-GUIDED OPTIMIZATIONS
by Gary Carleton, Knud Kirkegaard, and David Sehr
Profile-guided optimizations feed information about how a program executes back to the compiler. This allows the compiler to focus its efforts more effectively on the regions of programs that matter for execution time.
PROGRAMMING PARADIGMS
by Michael Swaine
Y2K guru Bob Bemer takes time out to chat with Michael about a big problem...the early days of Cobol and the latter days of the Y2K problem.
C PROGRAMMING
by Al Stevens
Al implements a C++ version of the Midifile C function libraries that parse MIDI files. He then takes a look at Bjarne Stroustrup's The C++ Programming Language, Third Edition.
JAVA Q&A
by L. Richard Moore
Streaming audio refers to audio that can be downloaded at the same speed it is played. Rick presents idtAudio, a streaming audio applet written in Java.
ALGORITHM ALLEY
by John Boyer
John introduces algorithms for and implementations of linked-list sorting and searching that are more efficient than those available in the Java Developer's Kit 1.2 Beta 2.
UNDOCUMENTED CORNER
by Robert R. Collins
In previous columns, Robert examined why Intel's Virtual Mode Extensions (VME) are needed and how they work. This month, he wraps up his analysis of VME by pointing out some of its caveats.
DR. ECCO'S OMNIHEURIST CORNER
by Dennis E. Shasha
Dr. Ecco and crew tackle the problem of "nimmerics," which even stymied the Feds.
PROGRAMMER'S BOOKSHELF
by Peter N. Roth
Peter takes a look at Fuzzy Engineering, by Bart Kosko, Applications of Fuzzy Logic, edited by Mohammad Jamshidi, Andri Titli, Lotfi Zadeh, and Serge Boverie, and The Design and Development of Fuzzy Logic, by Byron Miller.
