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.

System Administration Toolkit: Monitoring disk space and usage
Look at methods for determining disk usage across multiple UNIX(R) systems and how to create a simple warning system to alert you of potential problems. Keeping an eye on your file systems and ensuring they don't fill up is a trivial, but vital, process in the day-to-day management of your UNIX systems. In this article, you'll look at methods for keeping an eye on disk space, discovering which files, users, or applications are using up the most space, and how to make use of quotas and other solutions to find the information you need.
