"A typical piece of professional software contains up to 50 errors per 1,000 lines of code. But scientific code, which is written mainly by graduate students and postdocs who have little to no training in software development, is even more error-prone."
"If you have a program that computes something, it doesn't mean that it's correct. The worst kind of code is code that executes but is wrong."
"Debugging is like a detective story where you are both the investigator and the murderer."
"Document the conditions that cause the bug to appear. Is there a problematic input, for instance? If possible, identify a minimal working example."
Scientific coding is increasingly important but often flawed due to the inexperience of those writing the code. Many researchers, primarily graduate students and postdocs, lack formal training in software development, leading to high error rates. Debugging is a critical skill that is seldom taught, yet it is essential for ensuring code accuracy. Experts suggest documenting bug conditions and creating minimal working examples to aid in debugging. The complexity of debugging is likened to a detective story, emphasizing the need for thorough investigation.
