Programming Ruby 3.2 (5th Edition): B4.0 page 603, program_name = nil
page 603, second to last paragraph, first line : program_name instead of progname
You add new entries to the log with Logger#add(severity, message = nil, program_name = nil),
-----> ^^^^^^^^^^^^
The documentation uses progname, or the paragraph above starting with Valid keyword arguments for the options hash.
