Todd E. Sundsted writes about network transparency issues on IBM's developerWorks. "Distributed applications benefit from network transparency. Unfortunately, many common network devices -- like firewalls and NAT gateways -- destroy network transparency, often at the edge of the network where the potential for innovative distributed applications is greatest. In this article, veteran Java programmer Todd Sundsted explains how network transparency can be compromised by these devices, and then lays the foundation for a solution."

10 Reasons We Need Java 3.0 (O'Reilly)

Elliotte Rusty Harold writes about the need for Java 3.0 on O'Reilly. "It's now a little more than 11 years after James Gosling began working on OAK, the language that would eventually become Java, and seven years since Sun posted the first public release of Java. The language, class library, and virtual machine collectively known as "Java" are all showing their age. There are many parts of Java that everyone agrees should be fixed but can't be, for reasons of backwards compatibility. Until now, revisions of Java have attempted to maintain "upwards compatibility;" that is, all earlier code should continue to run unchanged in later versions of Java. This has limited the changes that can be made to Java, and prevented Sun from fixing many obvious problems."

CASE Tools: Large System Development (O'Reilly)

David HM Spector covers progress in the area of Computer-Aided Software Engineering (CASE) tools for Linux. "A few years ago, it would have been impossible for a Linux system to play in this sandbox: the limitations of the file systems alone would have squelched the idea. Fortunately, the Linux world moves very quickly. The availability of larger SMP systems, in fact whole IBM 390 Mainframes running Linux, and fast, journaling file systems like ext3 or ReiserFS without the old 2GB limit, and logical volume management, all mean that there are few limitations beyond cultural inertia and bias that are stopping Linux from becoming a player in this space."
