A good point and definitely contains some trues:
„If you get in the habit of using a debugger,“ my mentor pointed out, „you’ll get lazy. A certain part of your brain shuts off, because you expect the debugger to help you find the bug. But in reality, you wrote the bug, and you should be able to find it.“
Still stunned, I asked: „What do you do when you have a really nasty bug?“
He said something I’ll never forget. „I make the machine tell me where it is.“
Make the machine tell you where the bug is. What a wonderful piece of advice. It’s the essence of troubleshooting, whether you’re trying to fix a car that won’t start, trace an electrical fault, or debug a piece of software.
