I am reading the Effective go book. I thing I found a typo. In the following paragraph:

Embedding types introduces the problem of name conflicts but the rules to resolve them are simple. First, a field or method X hides any other item X in a more deeply nested part of the type. If log.Logger contained a field or method called Command, the Command field of Job would dominate it.

log.Logger must be replaced with job.Logger, I guess.
