Tools of the Trade Icon

Welcome to Tools of the Trade

This podcast of an ongoing IEEE Software column explores the interplay between you, the software practitioner, and the tools you apply to the development problems you face. Skilled craftsmen set themselves apart from amateurs by the tools they use and the way they employ them. As a professional, I feel I'm getting a tremendous boost in my productivity by appropriately applying tools to the software construction problems I face every day. I also often find myself developing new tools, both for my personal use and for wider distribution. Column installments will discuss specific software construction activities from the standpoint of the tools we can employ — the tools of our trade. Future topics include editing, compiling, documentation, debugging, testing, configuration management, issue tracking, the development environment, tool building, and domain-specific tools. Of course, your suggestions are always welcome; email me at dds@aueb.gr. Diomidis Spinellis

Differential Debugging

Finding yourself in a situation with a working and a buggy system is quite common. Differential debugging methodically can help by comparing a known good system with a buggy one, working toward the problem source. Some simple steps include applying differential debugging by looking at log files and increasing a system’s log verbosity when needed. If the system doesn’t offer a sufficiently detailed logging mechanism, you can tease out its runtime behavior with tools that trace calls to the operating system or that trace network packets. You can also compare carefully the two environments where the systems operate.
