What is the most recommended (or the conventional) way of naming methods
in
Ruby? Do they need to be verb-like or noun-like? In other language like
C++,
methods are supposed to be verbs because they are dimmed as messages
sent to
the object. I have asked this because methods in Ruby are also objects.

Not exactly. There was a lengthy discussion here about whether
methods are objects or not. Strictly speaking they are not, but you
can obtain an object representing a bound or unbound method.

methods that modify the object (or caller) itself, should be exclamations:
obj.truncate!
obj.remove_name!
obj.date! “Julian” # I wish I could do obj.date “Julian”!, instead. Ah, well.
I think the conventional wisdom is that this should only be done only if
there is a matching non-mutating method that has the name without the
exclamation mark.

Well, I can’t speak for Rubyists in general, but I aim for the
following:
methods that do something should be verbs:
obj.calculate
obj.set_name
obj.get_date
methods that are accessors (or behave like them) should be nouns:
foo = obj.name
puts obj.date
obj.calculation
Interrogative methods get phrased as questions:
obj.date_today?
obj.name?
obj.calculation_done?
methods that modify the object (or caller) itself, should be
exclamations:
obj.truncate!
obj.remove_name!
obj.date! “Julian” # I wish I could do obj.date “Julian”!, instead.
Ah, well.

Though the folk I have met,
(Ah, how soon!) they forget
When I’ve moved on to some other place,
There may be one or two,
When I’ve played and passed through,
Who’ll remember my song or my face.

Someone may give more info on why it should be like this:

I think you left something off. Anyway…
Here is a great explanation of the ‘!’ naming convention:
