Delivering a bug-free application to consumers is not a perfect or realistic process. It not only saves the time of software developers but also saves their energy. The data sets for production are not identical to the datasets for QA or development. Personally when I run into a bug, I recheck the code, try to trace it in my mind from the program logic, because that sometimes helps me uncover other problems or side effects easier than just using the debbuger and fixing the bug where it manifests itself. But by adhering to the above principles, the defect is easier to locate, and debugging doesn't mean a painful, indeterministic process. In the Pern series, what are the "zebeedees"?

In my experience, I find using the debugger to be very useful because it helps to reveal false assumptions that I was making about the state of my code. The last thing you want to do with log statements is to create new issues. Advantages Single step through the code; Stop execution at a given point to investigate where it goes and what the values are; Attach to an already running program; Disadvantages Not running real-time, so may not expose all problems; DDD How to Compile for Debug. That way, you can cover most of the problems and hence there would be no need to use the debugger. Unique situations can still arise, either because nuances were missed in the development or testing phase or the production environment differs from the one used in development or testing. 1.

Then you have the cost of creative development when taking this marketing approach to consider. Debugging by guessing might work if you already have an idea about what the bug is (incorrect value passed to a library function, possibly invalid SQL, etc). It only takes a minute to sign up. In particular, the position of "There are important debugging aides to spend development time supporting" might be orthogonal to the importance of debuggers. As long as a developers is familiar with a few of the techniques for their platform/tool, in addition between just rechecking the code, then they may be a skilled developer, but if they only have one trick when it comes to debugging then they will eventually run into a bug they cannot find or fix. Wikipedia has a page on the advantages and disadvantages. Youll be fast and reliable and to others youll be the human interface to the apps code and its relations.
