    1. What does 'passing an argument' mean in programming?You have a grinder that will grind anything that you pass on to her. You give her Rice. She grind it. You give her wheat. She grind it. You give her a Justin Bieber song CD. She grind it. She grinds every thing that you hand over to her. In programming, we create function that does the stuff we need. Say add, subtract, multiply or print the stuff that you pass on to it. Then we pass on stuff upon which the function will operate and return us the results. This process of passing the 'stuff' to be processed is referred to as passing an 'argument' in programming. Thank You.

    1. "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 (...)

    1. Go Programming Language publicly in 2009 they were also looking to solve certain challenges of the existing Computer languages. Of the many features that it demonstrated (we will get to those soon enough) it was also helpful in addressing the strange dilemma of hardware and software that was emerging.

      Golang is a modern computing language, designed especially for modern computing needs.

    1. Neil Fraser says Vietnam is doing well with computer science education.

      "If grade 5 students in Vietnam are performing at least on par with their grade 11 peers in the USA, what does grade 11 in Vietnam look like? I walked into a high school CS class, again without any advance notice. The class was working on the assignment below (partially translated by their teacher for my benefit afterwards). Given a data file describing a maze with diagonal walls, count the number of enclosed areas, and measure the size of the largest one."

    1. Great Principles of Computing<br> Peter J. Denning, Craig H. Martell

      This is a book about the whole of computing—its algorithms, architectures, and designs.

      Denning and Martell divide the great principles of computing into six categories: communication, computation, coordination, recollection, evaluation, and design.

      "Programmers have the largest impact when they are designers; otherwise, they are just coders for someone else's design."

    1. In 1980 Joachim Lambek showed that the types and programs used in computerscience form a specific kind of category. This provided a new semantics for talking aboutprograms, allowing people to investigate how programs combine and compose to createother programs, without caring about the specifics of implementation. Eugenio Moggibrought the category theoretic notion of monads into computer science to encapsulateideas that up to that point were considered outside the realm of such theory.

    1. “Many random number generators in use today are not very good. There is a tendency for people to avoid learning anything about such subroutines; quite often we find that some old method that is comparatively unsatisfactory has blindly been passed down from one programmer to another, and today’s users have no understanding of its limitations.”— Donald Knuth; The Art of Computer Programming, Volume 2.

      Mike Malone examines JavaScript's Math.random() in v8, argues that the algorithm used should be replaced, and suggests alternatives.
