I'm asked to teach my students Eclipse.
The lectures are already done; I see that the teacher asks the students to always start a new project in "Release" mode.
Is this a good idea? If "yes", or if "no", why?
Not sure if this is normal or not but in general it is a matter of preference for the teacher.
I am not sure that not letting students debug their programs is any good for learning but I would ask him the reason why he limits this.
One thing that I can think of is to teach the ability to add another build configuration if problems arise.
