Clean Code

Week-15: 12/21/2024

It’s easy to get something functional, but is it good? The book “Clean Code” by Robert C. Martin shows how my past coding techniques were wrong. This book isn’t just about making code work; it’s about crafting code that is understandable, maintainable, and, dare I say, beautiful.

The book highlights the importance of seeing code as a kind of communication rather than simply computer instructions. It’s about creating code that’s simple to understand, alter, and, ultimately, live with. The book provides several definitions of clean code, including the following: elegant, efficient, simple, straightforward, and carefully crafted. It also covers ideas and practices including utilizing meaningful names, constructing concise functions, correct commenting, formatting, error handling, unit testing, and so on. The book depicts the transition from sloppy to tidy code. It also includes a collection of code smells or heuristics that might help you write better code. 

I chose this book because I often find myself spending more time deciphering what code does than actually adding new features. I was looking for guidance on how to avoid creating such a mess and to understand what makes code easy to work with, and the book seemed highly relevant to my goals as a student. I also appreciated the idea that code is read far more often than it is written, so making it easy to read is very important.

This book has opened my eyes, particularly to the importance of code readability. It is not enough to have code that is functional; it must also be understandable to everybody who will work with it. This is particularly crucial in collaborative efforts. The author’s description of “code sense,” a carefully developed feeling of ‘cleanliness,’ struck a chord with me. Knowing that code should be clean isn’t enough; we also need to learn how to make it clean. 

I will be putting the principles of “Clean Code” into practice by always striving to leave the code cleaner than I found it. I also plan to be more diligent in naming variables and functions, keeping functions short and focused, and implementing tests to validate and describe code. This book has taught me that clean code is more than a nice-to-have; it is an important component of becoming a professional software developer. I now recognize that “working” code is only the first step; “good” code needs ongoing attention and effort. I’m excited to implement these concepts into my future projects, not just to improve my grades but also to gain more experience programming software.

Understanding the Software Development Life Cycle (SDLC)

In software development, having a structured plan is crucial for creating reliable and efficient software. The blog post “What Is the Software Development Life Cycle (SDLC)?” explains what the SDLC process actually is. This directly relates to our coursework, as it lays out the core stages involved in creating software that we’ve discussed in class.

Summary of the Blog Post

The post breaks the SDLC into six main phases:

1. Requirement Analysis – Figuring out what the software needs to do.

2. System Design – Mapping out how the system will work.

3. Implementation – Writing the actual code.

4. Testing – Making sure everything functions as expected.

5. Deployment – Releasing the finished product.

6. Maintenance – Keeping the software updated and fixing bugs after launch.

The post also touches on different SDLC methodologies like Waterfall, Agile, and DevOps.

Why I Picked This

I chose this post because the SDLC is something we covered in class, and I felt like I could benefit from looking into it more. This post explained things in a simple way that helped me review and learn more about the process. Plus, SDLC is something I’ll definitely encounter in any future dev job, so it feels suitable to dive deeper into it now.

Thoughts and Takeaways

This blog really helped me get a better grip on SDLC. I knew the general ideas, but breaking down the phases step by step helped me realize how important each stage is. For example, I hadn’t thought much about how critical the requirement analysis phase is. If you get that wrong, everything else suffers!

I also liked the section about Agile. I’ve heard a lot about Agile but didn’t fully get how it compares to other models like Waterfall. The idea of working in iterations and being flexible with changes makes sense, especially for real-world projects where things don’t always go as planned. I think this will be useful for group projects where feedback loops are constant.

Another thing that stood out is how much emphasis the post put on maintenance. In class and in the blog post, its been made much more clear that maintenance is actually the far lengthier phase, and sometimes never really intended to end.

Applying SDLC

Going forward, I’m going to start structuring my projects with SDLC in mind. Even on smaller assignments, I’ll try to break tasks into phases, just to get into the habit. I also want to experiment more with Agile practices in team projects since it seems to encourage collaboration and adaptability, and is mentioned in a decent amount of job posts.

Conclusion

This blog post gave me a much clearer understanding of SDLC and why it’s such a core idea of software development. It affects nearly every bit of how software comes to be, and all software developers will encounter or deal with it in one way or another!

GIT(ting) My Friend A Promotion

For teams of developers having a centralized repository for code is essential. Git provides an extremely powerful and relatively user-friendly base for teams to collaborate effectively.

After teaching one of my close friends, involved in a development project at work, the basics of class diagrams. They gave her a more hands-on role with the entire development process. Even though she had never worked with programming before, having someone in a business oriented role who could communicate and check over the team of developers was perfect for them.

That’s when she was selected as the product owner for her company’s new website. In a serendipitous twist they were using git as their repository while I simultaneously was being taught about it in school.

The next step was to teach her a basic overview of how it all looks from a developers perspective.

We started with a picture from my professor.

At first glance, I had completely lost her. After explaining that she wasn’t the maintainer responsible for handling all of this her mind was eased a little. The main ideas were just to understand the flow of how the developers were going to be working. All she had to remember was FCBPP.

This acronym I created for her was simple. They would FORK their own copies. Make CLONES of that. Make a BRANCH where they would do their work. PUSH that work kind of like a save. Then create a PULL request. As a developer it is obviously a lot more nuanced and there are more steps involved. But for someone that isn’t actually doing hands on work that was enough.

After getting the gist of it and before getting further into the details of how it would benefit her to know that stuff. We took a look at the stuff she would really be involved with. The product and sprint backlogs.

In git it is actually fairly easy for someone who doesn’t really understand programming itself to look at, arrange and audit backlog items. It would also allow her to check in regularly to see where the team was when her boss would ask questions.

In the real life case while explaining this part we did use the real github of her company but for the sake of confidentiality it will be a new blank project.

I told her to focus on the issue board under planning. It looked similar to this:

With properly labeled boxes and the lists of items and features the team was working on or planned to work on she felt so much more comfortable asking about things and helping plan everything out. After circling around the topic a few more times we realized just how powerful having a product owner who knows this process could be

We also joked with her boss that with me teaching her these things I should be hired as a consultant (small business unfortunately) with a bonus for my professor.

 coding understandable program

For anyone who codes a  program, it is important to not just have a working program, but to have  a  program  that is   easy to understand, whether you publish your program onto github, or you want to  review  your program after finishing it. Clean code is a term that was first introduced by Robert Cecil Martin, also known as Uncle Bob. He wrote a book that gives best practices and tips for writing understandable and working code. 

When creating formulas for writing code, instead of including numbers in a formula, which could lead to confusion for  a number’s purpose in   a calculation. Creating   a variable that explains it’s purpose in a code makes calculation clear. Comments can explain the meaning of a statement in a  code,  and while comments can  attempt to clear up any confusion for anyone viewing code, it should not be used to explain a obvious statement, but to explain certain actions  in code. For constructing functions, it’s best to have a function perform one action, and if a function is very lengthy, a function should be broken down into multiple functions. 

When writing code with multiple nested if else conditions,  to  make a program easier to understand,  if else conditions should be split  into descriptive functions. As someone who has worked with different programming languages, I would want to use the practices of clean code, to write a working program that I can review and understand if i revisit my work.

The Modern Standard for Collaboration: Version Control

Introduction

Version control is important for modern software development, enabling teams to collaborate effectively, manage changes, and maintain code quality. The blog post “Version Control Best Practices” by Tobias Günther offers 10 tips on how to use version control systems (VCS) like Git more efficiently.

Summary

The blog outlines essential best practices for working with version control systems, focusing on enhancing productivity and reducing errors. There were ten points but here are the top 5 most important in my opinion:

  1. Use Branches: Branches allow developers to isolate changes, experiment, and test without impacting the main codebase.
  2. Commit Often: Regularly committing small changes ensures incremental progress and simplifies debugging.
  3. Write Good Commit Messages: Clear, detailed commit messages help team members understand the context and purpose of changes.
  4. Go Beyond the Basics: Developers should invest time in learning advanced Git features like interactive rebases and cherry-picking to enhance their workflows.
  5. Don’t Commit Half-Done Work: Each commit should represent a complete, functional unit to maintain repository stability and clarity.

Why I Chose This Blog

I chose this blog because version control is a fundamental skill for software development, yet its nuances are often overlooked in coursework. While I’ve used Git for assignments, I realized that my approach lacked the deeper understanding laid out in this blog.

Reflection

There was a big emphasis on commits, which makes sense as commits are an integral part of version control and most of the tips talked about in the blog are practices that I do regularly, such as writing good commit messages. I don’t think it’s particularly hard to understand these standards for version control, and once you know them it’s just the norm to follow them.

Branching was something that I hadn’t known about prior to learning about it in class, but it makes sense to separate each new feature into its own area to work on instead of putting everything in main. This “tip” is really just a necessary way to stay organized and keep the repository and its pull requests in order.

Going beyond the basic features of git like committing and pushing is also a great tip, because although you could navigate git with only the basics, learning the more advanced features like rebasing can help greatly in certain situation where you’d be happy you know how to do it.

Future Application

There were some takeaways from this blog that I could incorporate into my own workflow. I think that I should commit more often than I do. I tend to forget to commit and only do so when I stop working but by then there could be a few features that are all crammed into one big commit.

How to review code effectively: A GitHub staff engineer’s philosophy

For my final blog post for the semester, I wanted to pick a topic that was different from project management, since I had already written about that a few times. Since our most recent topic in class revolved around GitHub and git commands, I wanted to explore a blog post that aligned with that topic. I came across a blogpost by GitHub staff engineer Sarah Vessels, from the github.blog page, about code review.

In this article, code reviewer Sarah Vessels discusses some practices to help improve code reviewing and make it more useful and efficient for everyone involved. She advises constantly checking your GitHub notifications inbox, anytime you have a spare moment. She also recommends using GitHub Slack Integration. Certain queries can help filter a slack group for finding outstanding pull requests that need review. We used Discord for our class instead of Slack, but as I understand it, Slack is more common in the professional world. I believe Discord has equivalent queries that can be used, anyway. The next piece of advice she gives is to use reviewer teams to manage notifications. While catch-all code owner teams can be okay as a fallback, it’s better to keep the number of code owner teams your own small, so that anything you get pinged for or anything that shows up in your inbox feels relevant to you, and not just something to ignore.

The next part she discusses, which I feel is the most important advice, revolves around giving good, constructive code review that doesn’t across as lazy. Good code review focuses on specifically saying,” I have a problem with this, maybe you should try xyz instead” instead of saying “I don’t like this” or “This won’t work” and leaving it at that. It’s good to ask questions, because the person who authored a pull request has more context for their changes, and gives them a space to explain and justify their reasonings. Personal preferences are fine, but approval should be about the overall integrity of the code. If the changes won’t break anything or affect production, leave the feedback with a comment but still approve the pull request anyway to keep the process moving. This is something I personally appreciate from the author, because while I don’t mind receiving feedback and improving my part of the process, I hate the feeling of holding back the overall process. This allows opportunities to open discussion without causing a holdup.

She has a few other suggestions in her blogpost, like being gracious and using draft pull requests, but I believe the most important things are her advice about the giving good feedback and managing notifications so you feel compelled to give every notification your full attention. I don’t know how much code I’ll be reviewing in the near future, but if I’m ever in this situation, on either side, this is good advice for me to keep in mind and remember.

scrum

Scrum is a framework that teams use to organize themselves in a project to reach a common goal. The values that members of a scrum team value are commitment, courage, focus, openness, respect. Scrum team is open to new ideas and opportunities, respecting each other, and have patience for the scrum process, and focusing on time-consumed tasks, and finding space for improvement. 

Scrum deliver a product for customer in a time period called a sprint. Product Backlog is the to-do list for a team which contains the requirements for a project. Product owner, which is one of the scrum roles, is responsible for maintaining and adding updates for the list, removing and adding new requests from customers. Sprint backlog is lists of items from the product backlog that is worked on during the current sprint. Increment is the end product of a sprint. 

The product owner guides the team on the next steps in the scrum process and ensures that the team understands the requirements that a business or client wants. The Scrum leader is responsible for making sure the scrum team works effectively. When working in a scrum team, there are different types of events that the scrum team is involved in.  Sprint planning is when teams estimate how much work needs to be done in a sprint. Daily Scrum is a short meeting where team members plan for the day, and provide updates on challenges experienced, and what work has been done. Sprint Review is the period at the end of the sprint, where the team reviews the work that has been completed, and presents it to stakeholders. Sprint Retrospective is when a team comes together to discuss the sprint result and make adjustments for future scrums. 

This semester in  CS 348, I had learned about scrum. With learning scrum, I was able to see how software team deliver products for clients.
