Introductory Post for CS-343

Welcome! First I would like to point out that all posts for this course should all be placed in roughly the same categories. However, they all will be tagged with CS-343. This should make them easy to find.

These posts will be centered around me searching for online materials other people have posted that relate to the core topics of CS-343. I will then be sharing them, interpreting them, etc. It will be a collection of information primarily useful to the following topics (as taken from the course syllabus):

  • Design Principles
    • Object Oriented Programming
    • SOLID
    • DRY
    • YAGNI
    • GRASP
    • “Encapsulate what varies.”
    • “Program to an interface, not an implementation.”
    • “Favor composition over inheritance.”
    • “Strive for loosely couples designs between objects that interact”
    • Principle of Least Knowledge
    • Inversion of Control
  • Design Patterns
    • Creational
    • Structural
    • Behavioral
    • Concurrency
  • Refactoring
  • Smells
    • Code Smells
    • Design Smells
  • Software Architectures
    • Architectural Patterns
    • Architectural Styles
  • REST API Design
  • Software Frameworks
  • Documentation
  • Modeling
    • Unified Modeling Language
    • C4 Model
  • Anti-Patterns
  • Implementation of Web Systems
    • Front End
    • Back End
    • Data Persistence Layer

Hopefully, these posts provide you with many resources to help you learn these topics for the first time or to help you recall them after a long time has passed! I wish you the best of luck in whatever you’re hoping to achieve!

Apprenticeship Patterns Introductions

After reading the Apprenticeship Patterns book introductions and a few of the patterns, I have to say they are very straightforward, which the book itself admits. The utility in reading them is that is is very easy to forget these ideas, or never apply them to your work.

I was ready to condemn the book from the beginning, as it introduced the idea of apprenticeships in medieval through industrial revolution times. I thought to myself how naive it is to write a book about such bad situations, and that the authors must be romanticizing this time. This thought was immediately shut down as I read the line, “we believe it is possible to reject the romantic fantasy”, in favor of something better. This served to drive further points home, as I had just fallen victim to some of the behaviors it warns against.

This book describes patterns that “are tools that solve one set of problems and create new ones.” And it says that “the trick is to use your judgment to choose the problems you prefer.” I love this idea because it illustrates the fact that one doesn’t need to be able to solve every problem if you can figure out how to solve it with the tools already at your disposal.

At the same time, it provides a framework for learning more tools. The idea of “exposing your ignorance” stands out most, because most of us want so badly to be intelligent and competent. Having spent some time in the workforce without a degree, I have become sensitive to this: trying hard to prove that I’m not “dumb”. Maybe it was actually that, that had slowed me down.

On “Emptying the Cup”

It’s always a good reminder that you might not know as much as you think. Or if you do, that you might be biased and closed to new ideas. I am very proud of some of my work, having had moments where I feel like a programming God, and in the face of a new technology, I am always humbled. But I feel that I run the risk of using my past professional and education experiences get in the way of new methods.

On “Accurate Self-Assessment”

I had to read some of these patterns, because I tend to self-assess in the negative direction. I already usually assume I’m “the worst”, or that my work isn’t good enough, and seek improvements. Still, the patterns themselves are useful, describing how to solve this problem. I tend to spend too much time assessing. I need to consciously tell myself to move on to new things, rather than dwelling on what has been done and how it can be done better.

…And Onward

My capstone team has been discussing learning some new technologies, and these introductions have lessened the fear of diving in and trying them. At the end of my college career, I have been reflecting on what I could have done differently, or how I could have done it faster, so this book comes at the perfect time.

Haven’t we all sometimes wanted a chance to start over again? How exciting to have a chance to be at the beginning of something.
