A TEXT UI FOR THE JAVA AWT

by Stuart D. Gathman

Stuart presents a text user-interface toolkit for the Java AWT that allows ASCII terminals to run Java applications on UNIX servers. In addition, the toolkit enables a multiuser Virtual Machine.

TAGGED DATA STORAGE

by Jeremy Vineyard

Tagged data storage improves the efficiency and robustness of your data-storage architecture and decreases the time you spend writing code to store and restore data.

JAVA DEADLOCK

by Allan Vermeulen

One of the primary motivations for using Java-and one of its biggest advantages to developers-is safety. Still, Java does nothing to protect you from deadlock-a nasty problem where a program simply stops executing because all threads are waiting for a resource that will never become available. Allan examines Java deadlock and shows how it can be prevented.


EMBEDDED SYSTEMS

FIREWIRE: THE IEEE 1394 SERIAL BUS

by Thomas Tewell

FireWire, also known as IEEE 1394, may pave the way for a true convergence of consumer electronics and computers. Thomas presents a fully functional Win32 console application that takes a snapshot from the CCM-DS250 digital camera, converts it from a YUV format to a 24-bit device independent bitmap (DIB), and writes the DIB to a file.


INTERNET PROGRAMMING

SERVER-SIDE SCRIPTING IN VISUAL BASIC

by Al Williams

Al shows how you can transform a boring web page into an interactive powerhouse using Visual Basic, IIS 3.0, VBScript, and server-side ActiveX components.


PROGRAMMER'S TOOLCHEST

STEREOSCOPIC IMAGING

by Andy Ramm

Stereoscopic imaging gives you the ability to deliver a user interface that provides a natural 3-D view of an object or scene, dramatically increasing technical proficiency and the ability to interpret multidimensional data.

LEVERAGING ORACLE POWER OBJECTS 2.1

by Douglas C. McArthur

Douglas describes how Oracle's visual development tool Power Objects 2.1 was used to develop MDLSCREEN, an Oracle-based client/server data-management system for automated drug discovery and high-throughput screening.


COLUMNS

by Michael Swaine

Will Apple's bridge to the future be a bridge over troubled waters? Based on the goings-on at this year's World Wide Developer's Conference, Michael looks at what the future might hold for Apple.

C PROGRAMMING

by Al Stevens

Al's scratching his head over what's going on with the proposed C++ standardization.

JAVA Q&A

by Clif Berg

JavaBeans, Sun's answer to component software, are reusable components that can be visually manipulated. Cliff shows you how to build a Bean.

ALGORITHM ALLEY

by Bob Jenkins

What makes one hash function better than another? Bob knows the answer, and he has used his knowledge to design a new hash function that may be better than what you're using now.

UNDOCUMENTED CORNER

by Robert R. Collins

Robert continues his discussion of in-circuit emulators. This month he describes how microprocessor design has evolved with in-circuit emulation in mind, and the changes that occurred within the microprocessor itself in the process.

PROGRAMMER'S BOOKSHELF

by Gregory V. Wilson

Gregory examines a bevy of books: Understanding ActiveX and OLE, Garbage Collection: Algorithms for Automatic Dynamic Memory Management, Modern Compiler Implementation in Java, Growing Artificial Societies, and Java Design: Building Better Apps and Applets.
