I see mentions of gdb - an extremely cumbersome tool - no mention of Visual Studio and its marvelous debugger.

I too, when I'm on Linux, don't use a debugger, because there's no good debugger and adding a print statement is faster and easier, and figuring out what is going on with gdb is just plain horrible and slow.

That's why as soon as I find a bug on Linux I try to have it on Windows to leverage VS's debugger. I can't count the number of times where I could instantly spot and understand a bug thanks to VS's debugger.

"Think harder about the code", sure, and what if you didn't write the code?
