      "Context" manipulation is one of big topic and there are many related terminologies (academic, language/implementation specific, promotion terminologies). In fact, there is confusing. In few minutes I remember the following related words and it is good CS exam to describe each :p Thread (Ruby) Green thread (CS terminology) Native thread (CS terminology) Non-preemptive thread (CS terminology) Preemptive thread (CS terminology) Fiber (Ruby/using resume/yield) Fiber (Ruby/using transfer) Fiber (Win32API) Generator (Python/JavaScript) Generator (Ruby) Continuation (CS terminology/Ruby, Scheme, ...) Partial continuation (CS terminology/ functional lang.) Exception handling (many languages) Coroutine (CS terminology/ALGOL) Semi-coroutine (CS terminology) Process (Unix/Ruby) Process (Erlang/Elixir) setjmp/longjmp (C) makecontext/swapcontext (POSIX) Task (...)

    How do I create an average from a Ruby array?

    1. TylerRick 08 Jun 2021
      Programmers should be encouraged to understand what is correct, why it is correct, and then propagate.

      new tag?:

      • understand why it is correct
      good advice programming: understand the language, don't fear it quotable annotation meta: may need new tag programming languages: learning/understanding the subtleties having a deep understanding of something combating widespread incorrectness/misconception by consistently doing it correctly spreading/propagating good ideas

    Inheriting class methods from modules / mixins in Ruby

    1. TylerRick 13 Apr 2021
      It seems inelegant to me to split this into two different modules, one to include, the other to extend.

      the key thing (one of them) to understand here is that: class methods are singleton methods

      inelegant inconsistent depends on how you look at it Ruby: modules Ruby: class methods Ruby: singleton methods programming languages: learning/understanding the subtleties

    Ruby classes inherit methods on singleton classes
    1
    1. TylerRick 13 Apr 2021
      Apparently when you create a subclass, that subclass's singleton class has # its superclass's singleton class as an ancestor.

      This is a good thing. It allows class methods to be inherited by subclasses.
