What does "monolithic" mean?

I've seen it in the context of classes. I suspect it means that the class could use being broken down into logical subunits, but I can't find a good definition. Could you give some examples?

Could someone tell me what exactly NSCFTimer is? I get it when I ask NSTimer for a timer.

Does this "NSCFTimer" in any way... hinder the process? ...

lua - capturing variable assignments

Ruby has this very interesting functionality in which when you create a class with 'Class.new' and assign it to a constant (uppercase), the language "magically" sets up the name of the class so it matches the constant. # This is ruby code MyRubyClass = Class.new(SuperClass) puts MyRubyClass.name # "MyRubyClass" It seems ruby "captures...

Benefits of using an abstract classes vs. regular class

I have decided to start doing small coding projects on my own that focus on code quality instead of code quantity and have a question about the use of abstract classes.

Having problems with a custom logging system I've made. I am declaring an ofstream within my main file so that it is accessible by static functions within my class.

Regarding C++ class access/manipulation in C.

Hello. I've been reading questions on Stack Overflow for a few weeks now... this'll be my first question. So recently I've looked into making C access/manipulate a C++ class. I understand that ideally one shouldn't compile components in C and C++ separately under normal circumstances, but this isn't an option at the moment. I looked in...
