Avoid traps when porting Java Web applications from Windows to AIX
Examine three traps you could fall in when porting Java(TM) Web applications from Windows(R) to AIX(R), and learn how to maneuver around them. When developing applications, you normally do so in a development environment and then deploy to a production environment. If you develop on Windows and deploy to a UNIX(R)-like platform, you might encounter subtle pitfalls. The first trap sets up different line separators in Windows and AIX, the second shows the best approach to locate a file in different development environments and operating systems, and the third is a common exception in socket communication.

Techniques for memory debugging
Exercise good memory-related coding practices by creating a comprehensive program to keep memory errors under control. Memory errors are the bane of C and C++ programming: they're common, awareness of their importance for over two decades hasn't eradicated them, they can impact applications severely, and few development teams have a definite plan for their management. The good news, though, is that they needn't be so mysterious.
