There's another methodology that Brian and Rob Pike miss.

Rather then stepping through a program. Add breakpoints and just step from breakpoint to breakpoint.

With a good IDE, adding a breakpoint and hitting a shortcut key is faster than a print statement and on the GUI IDE your debugging sessions are not transient.

The only time their advice makes sense to me is when I'm in an environment without a gui. Even then jetbrains has a "ssh full remote mode." However at my company I have found that this feature doesn't work under Nix (nix-shell) so we all just use print statements.
