There is more to object oriented programming. If you want to be able to write code that you can re-use 2 weeks after, you want to put attention to how to write good quality code. This activity takes time, but if you want to be able to look back at what you have done (and you want it!) you have to pay the price.

Next, consider the importance of commenting your code and the proper way to do it. This is a fundamental activity. However, more commenting is not necessarily better then less commenting.

This second set of talks digs deeper into the profession of software engineer/ programmer and promotes an attitude that fosters collaboration and ethics.

One of the problems that the industry is facing is that in the past 50 years, the number of programmers doubled every 5 years. Therefore, the industry remains young and the experienced coders face the trouble of passing their knowledge to the new generation. In one line: act professional!

Test driven development is a software development process that relies on the repetition of a very short development cycle: Requirements are turned into very specific test cases, then the code is improved so that the tests pass. This is opposed to software development that allows code to be added that is not proven to meet requirements. This, together with making correct estimates and saying no is the right attitude for delivering successful results.

Software architecture refers to the fundamental structures of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. In the video below, you will learn the fundamentals of software architecture, its rules, the value of discipline in the production of quality code, and the responsibility of disseminating the need to implement these good practices in the community of programmers.

Challenges in software and software management include the problem of adjusting software production time to delivery times. In other words, we are talking about the divergence between the needs of the client, the commercial commitments, and the needs of the programmer to produce quality software. Software project management is comprised of a number of activities, which contain planning of project, deciding scope of software product, estimation of cost in various terms, scheduling of tasks and events, and resource management. This last talk is about some of these challenges:

In summary, quoting from Uncle Bob:

Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way

Have you ever tried to solve a very important problem doing some programming but found stacked because you can not understand the code that you wrote the week before?

If you are writing code this is not happen yet in your life, it is doom to happen soon. If you plan to implement something as part of your thesis. I can guarantee you that it will happen!

The problem of how to write comments into the code is fairly common and well understood in business. Companies, in the attempt to mitigate this phenomena, create guidelines on how to comment the developed code in order to make it understandable by different employees.

Good comment practices can be applied in all possible programming languages. The goal is not to improve the speed or the consumption of memory. It is more related to focusing on let other humans understand what has the program does and why. By the way, that “other human” most of the time is your future self!

1: Write comments when you are writing the code

You should considering writing comments when you are writing the code itself. Otherwise, you will probably forget half of them and will spend twice the time in doing this task. In general, you will be the primary user of these comments as often will have to read again the code in order to modify its functionalities.

2: Every class a and functions should start with a description

A code should start with a general description of the program containing:

• The problem(s) that the code solves
• The data-structure(s) used in the code.
• What algorithms and techniques, are used in a particular piece of the program

Every functions should have a description of the general idea and the input and output should be explained

3: What you write matter

Know how to write a comment is more then just writing comments for the sick of writing comments . Consider the following when deciding what to write:

• Do not comment the obvious
• Do not comment what the code is doing
• Comment why you are doing it.

Below you can find a couple of videos that share some insight on how to comment. This first share a few best practices using Eclipse and Java as a framework of reference. The author also makes the a good point when he says that good code should be self-explanatory and shows a concrete example of that. Similar points can be made with Python code as well.

This video explain another set of best practices when commenting the code. However instead of focusing on Java use Python as reference language.

Independently of the language that you are using both these videos can help you in understanding common best practices that you should use in your code, Java, Python or anything else.

Other useful resources of understanding the basic of programming includes:

• Why you need an IDE
• The Basic of Object Oriented Programming (OOP)

Object-Oriented Programming has permeated almost every facet of modern software development. Its principles and concepts are applied in diverse domains, from software architecture and frameworks to user interfaces, game development, real-time systems, and beyond. OOP’s ability to enhance code organization, reusability, and maintainability has solidified its role as a foundational approach in the creation of complex and reliable software systems.

OOP leverage the concept of Classes and Objects and the following 4 paradigms:

• Abstraction: a process where you show only “relevant” data and “hide” unnecessary details of an object from the user.
• Encapsulation: a practice that bind the data with the code that manipulates it and keeps the data and the code safe from external interference
• Inheritance: the mechanism by which an object acquires the some (or all) properties of another object.
• Polymorphism: a way to process objects differently based on their data type. In other words objects can have the same name for a method but the implementation may differ.

If you are not familiar with these concepts I would recommend you to watch the following video that explains what is object oriented programming in a few minutes.

If you are familiar with Python and you want to see how these things work in practice I would recommend to follow the instructions in this video that explains how to create Python Classes using the Spyder IDE:

In the case you do not know what is an Integrated Developing Environment (IDE) this article will give you the basic and explains why you need an IDE.

If you put attention to the way the author of the video is writing the code you would probably notice that is following a certain naming convention. Some of these conventions are imposed by the compiler and there is no work around that. Other are best practices that will improve the readability of your code. As the majority of the example that you can find in internet follow these conventions I would recommend you to get familiar with the basic as you will save a lot of time in the long run.

This video introduce the basic (and most popularly accepted) conventions in JAVA. Python follow something similar as well:

More resources on naming conventions include:

• Camel Case in Wikipedia
• Naming Convention on Programming

Clearly this is just the tip of the iceberg of Object Oriented Programming. If you want to know more you could follow this class of MIT OpenCourseWare that should set a more concrete foundation if you are not familiar with the concept at all.
