I tend to agree with the author, but there are times comments are the only way to help the next guy looking at the code. Like when you're using workarounds. E.g., I was recently writing for a JPA entity on Google App Engine where I tried using a @PrePersist function to update a field. Turned out that GAE won't call the @PrePersist unless a field is updated first...i.e., catch 22. So, say as a workaround you add an artificial update to the field to null just so your @PrePersist is called, what are the odds that the next guy reading the code without a comment won't just delete that assignment thinking it's unnecessary?
