Computer Science is the scientific and practical approach to computation and its applications.

Computer Science

Computer science, the study of computers and computing, including their theoretical and algorithmic foundations, hardware and software, and their uses for processing information. The discipline of computer science includes the study of algorithms and data structures, computer and network design, modeling data and information processes, and artificial intelligence. Computer science draws some of its foundations from mathematics and engineering and therefore incorporates techniques from areas such as queueing theory, probability and statistics, and electronic circuit design. Computer science also makes heavy use of hypothesis testing and experimentation during the conceptualization, design, measurement, and refinement of new algorithms, information structures, and computer architectures.1

  • Computational Thinking : Computational Thinking is the thought processes involved in formulating a problem and expressing its solution(s) in such a way that a computer-human or machine—can effectively carry out.
    • Algorithms : Algorithms: a set of rules for solving a problem in a finite number of steps
    • Data Structures : Data Structures an organized form, such as an array list or string, in which connected data items are held in a computer
  • Design Patterns : a design pattern is a general repeatable solution to a commonly occurring problem in software design
    • Singleton Pattern : The singleton pattern is a design pattern that restricts the instantiation of a class to one object.
    • Dependency Injection : Dependency injection is a programming technique that makes a class independent of its dependencies.
  • AntiPattern : An AntiPattern is a literary form that describes a commonly occurring solution to a problem that generates decidedly negative consequences.


  • Informal History Of Programming Ideas
  • Obtaining a Thorough CS Background Online - I’d like to show you a way to obtain a computer science background that doesn’t involve enrolling in a university program. Maybe you’ve completed an introductory Java course, and now you’d like to pursue a software development position. Or maybe you already have some formal CS training, and you’d like to fill in a couple of knowledge gaps. By utilizing online learning resources, you can obtain that background without incurring the costs of the traditional university approach.

These four books comprise what easily could be the most important set of information on any serious programmer's bookshelf.

Introduction to Computation and Programming Using Python Introduction to Computation and Programming Using Python
This book introduces students with little or no prior programming experience to the art of computational problem solving using Python and various Python libraries, including PyLab. It provides students with skills that will enable them to make productive use of computational techniques, including some of the tools and techniques of data science for using computation to model and interpret data.

How to Read Code

Tips For Reading Code - One way to improve programming skills is to ReadGreatPrograms. Techniques such as SelfDocumentingCode and LiterateProgramming have been developed toward the goal of writing programs that can be easily read. However, most of us have to read lots of code that does not meet the above standards. What are the best ways to make sense out of those huge, unstructured, maintained-by-dozens-of-people, internally-inconsistent, undocumented code bases that we must understand and absorb?

One secret to becoming a great software engineer: read code - Become a better programmer by building a routine and habit for reading code

Don't repeat yourself (DRY)

In software engineering, don't repeat yourself (or do not repeat yourself; aka DRY) is a principle of software development aimed at reducing repetition of software patterns, replacing it with abstractions or using data normalization to avoid redundancy.2


SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable.3

The Twelve Factor App

The Twelve Factor App In the modern era, software is commonly delivered as a service: called web apps, or software-as-a-service. The twelve-factor app is a methodology for building software-as-a-service apps such that:

  • Use declarative formats for setup automation, to minimize time and cost for new developers joining the project;
  • Have a clean contract with the underlying operating system, offering maximum portability between execution environments;
  • Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration;
  • Minimize divergence between development and production, enabling continuous deployment for maximum agility;
  • And can scale up without significant changes to tooling, architecture, or development practices.

The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc).
