The first time I was taught about ‘Smells’ in code it was in connection Robert C. Martin’s “Agile Software Development, Principles, Patterns, and Practices“. For those who have not read it, starting from Rigidity we have Fragility, Immobility, Viscosity, Needless Complexity, Needless Repetition, and Opacity. All of these are categories of red flags in code, they are problematic because over time they make the code “hard to understand, modify, and maintain”. In an earlier post of mine, I talked about design patterns which are proven solutions to common coding problems. So when I saw an article talking about smells that can come from these design patterns I was intrigued. This eventually lead me to find out that the Singleton design pattern specifically is considered by many to be never good to use.

In an article titled “Examining the Pros and Cons of the Singleton Design Pattern“, Alex Mitchell first explains how the goal of the singleton design pattern is to “ensure a class has only one instance, and provide a global point of access to it.” He then goes on to list the pros, which, for those who do not know or remember, are; it insures only one instance exists throughout the code, it allows for that one instance to be called globally, and it limits access to that instance. Then he gets to the cons, first of which is it violates the single responsibility principle. Next up is the pattern’s tight coupling followed by how it complicates testing and finished with it obscuring dependencies. He then offers an alternative to singeltons in the form of Monostate or dependency injections and then a nice conclusion to wrap it up.

Lets go in order for the cons. Con #1: on a second look this seems obvious, the singleton class is simultaneously controlling its creation and managing access to itself. Con #2: again on second blush its because there only being one instance of the object means you cant use polymorphism or alternate implementations. Con #3: you cannot test in isolation since a singleton persists globally across tests. Con #4: the dependencies are not explicit when the singleton is used. The Monostate pattern allows for multiple instances to exist while having the same logical state, so while config1 and config2 can both change configValue, getting configValue from either config1 or config2 would return the same value. Dependency injection is, as far as I understand it, passing the singleton into the class that uses it, so rather than referencing the singleton it just has the singleton inside the class.

From this article I have come to a better understanding of dependency injection and will probably be using this framework in my future code since apparently a lot of code still uses the singleton pattern and dependency injection seems to best handle existing singletons.

A key aspect of frontend development is creating websites that perform well and provide a seamless user experience. However, due to time constraints in class, we didn’t have many opportunities to dive deeply into frontend implementation techniques. To fill this gap, I explored the blog “Frontend Development Best Practices: Boost Your Website’s Performance“. It’s clear explanations, organized structure, and bold highlights made it an excellent resource for enhancing my understanding of this crucial topic.

The blog provides a detailed guide on optimizing website performance using effective frontend development techniques. Key recommendations include using appropriate image formats like JPEG for photos, compressing files with tools like TinyPNG, and utilizing lazy loading to improve speed and save bandwidth. It stresses reducing HTTP requests by combining CSS and JavaScript files and using CSS sprites to streamline server interactions and boost loading speed. Another important strategy is enabling browser caching, which allows browsers to locally store static assets, reducing redundant data transfers and improving load times. The blog also suggests optimizing CSS and JavaScript by making files smaller, loading non-essential scripts only when needed, and using critical CSS to improve initial rendering speed. Additional practices include leveraging content delivery networks (CDNs) to deliver files from servers closer to users and employing responsive design principles, such as flexible layouts and mobile-first approaches, to create adaptable websites.

I chose this blog because it addresses frontend implementation topics that were not deeply explored in our course. Its organized layout, with bold headings and step-by-step instructions, makes the content accessible and actionable. As someone who plans to build a website in the future, I found its advice easy to understand.

Reading this blog was incredibly insightful. I learned how even small adjustments—such as choosing the right image format or enabling lazy loading—can significantly improve website performance. For example, understanding browser caching taught me how to make websites load faster and enhance the experience for returning users. The section on responsive web design stood out, emphasizing the importance of creating layouts that work seamlessly across different devices. The blog’s focus on performance monitoring and continuous optimization also aligned with best practices for maintaining high-performing websites. Tools like Google PageSpeed Insights and A/B testing offer valuable feedback to help keep websites efficient and user-focused over time.

In my future web development projects, I plan to implement the best practices outlined in the blog. This includes using image compression tools and lazy loading to improve loading times, combining and minifying CSS and JavaScript files to reduce HTTP requests, and utilizing CDNs alongside browser caching for faster delivery of static assets. I will also adopt a mobile-first approach to ensure websites function smoothly across all devices.

This blog has provided invaluable insights into frontend development, equipping me with practical strategies to optimize website performance. By applying these techniques, I aim to create websites that not only look appealing but also deliver an exceptional user experience.

YAGNI – You aren’t going to need it. In the simplest terms, the principle (initially created by Ron Jefferies) means don’t overengineer before it is necessary. It means to find the solution that works for what is needed today without engineering for POTENTIAL future scenarios. Outside of software engineering, this principle is applicable to everyday […]

The FreeCodeCamp article looks into helpful techniques for writing clean code, focusing on readability, simplicity, and naming conventions. It shows that writing clean code involves more than just making sure the code works. Using descriptive variable names, staying away from extremely complicated reasoning, and following recognized style rules are important pointers. The Medium essay supports this by going over fundamental ideas like the significance of refactoring, DRY (Don’t Repeat Yourself), and KISS (Keep It Simple, Stupid). Also, it emphasizes the human element of software development, clean code encourages teamwork and lowers technical debt. 

I chose these articles because they bring useful information into an important part of software development that is sometimes overlooked, especially with people who think they have finished code. They bring a deeper meaning to the information we learned in class about clean code and also how I should go about looking and editing any of the codes I make in the future. Another reason why I chose these articles is because they give useful knowledge about a sometimes disregarded aspect of software development. These materials show that clean code is about more than just functioning; it’s also about sustainability, readability, and future-proofing. Many developers may think their code is “finished” after it works well. These principles expand on the clean code writing lessons we acquired in class and provide a more comprehensive viewpoint on how to approach coding and editing in future projects. I found these tools to be a useful reminder of the importance of prioritizing clarity and maintainability above complicated solutions. For example, in previous classes where I needed to code, I often prioritized utility over the potential interpretation of my work. After reading these articles, I realized how important modular design and naming standards are for securing and debugging as well as group projects. 

Among the ideas that resonated deeply was “refactoring as a discipline.” Beyond just cleaning up code, refactoring provides an opportunity to reevaluate and just look over my coding another time. Refactoring provides a chance to reconsider and enhance a project’s overall structure. This viewpoint changed the way I approach coding. I now consider refactoring to be an essential step in maintaining long-term code quality rather than a tiresome task. It promotes a proactive approach to ongoing development. Going forward, I plan to integrate these principles into my coding practice. I will be more intentional about naming conventions, structuring code logically, and refactoring regularly. By doing this, I hope to create code that is not only functional but also clear, maintainable, and ready for future development.

Intro

Managing a team effectively is essential for delivering high-quality projects on time. A mismanaged team can lead to needless loss of productivity, whether it’s because of confusion between the team, or wasting time on useless tasks. This blog by Ben Brigden delves into strategies and practices that help teams collaborate efficiently, maintain focus, and deliver exceptional results.

Summary of the Source

The blog explores 9 tips of managing software development teams, but these are the main 5 I think stood out:

1. Clearly Define Goals and Expectations: Outlining precise objectives ensures everyone on the team is aligned and working toward the same outcomes.
2. Understand the Expertise of Your Team: Recognizing each team member’s strengths and specialties allows managers to delegate tasks effectively and maximize productivity.
3. Protect Your Team from Busy Work: Shielding developers from unnecessary tasks helps them focus on meaningful, high-impact work.
4. Emphasize Autonomy and Self-Reliance: Encouraging team members to take ownership of their tasks fosters independence and builds trust.
5. Measure Performance and Strive for Continuous Improvement: Using performance metrics and retrospectives ensures progress and helps refine team processes.

Why I Chose This Blog

This Blog is a good resource that goes over the top points about working in a software team effectively. It talks about all of the aspects of being in a software team that someone might want to know to better understand their role.

Reflection of the Content

The blog emphasized that team success hinges on communication and collaboration. One point that stood out was the importance of defining goals and expectations clearly. This is probably the most important thing in a software team. Without goals the developers become aimless and don’t know what to do or how what they are doing fits into an overarching plan. This is why agile development and scrum in particular is effective, as it sets clear goals within a certain time frame, with a definition of done, so everyone is on the same page of what needs to be done and what it means for their task to be completed.

The emphasis on autonomy is probably underrated in team environments, because I think people see the word team and assume that everyone has to know what everyone else is doing. Being trusted with your own work probably has a physiological effect on productivity as well, where when someone is given responsibility, they are probably more likely to live up to their potential as opposed to if they are being babied.

Future Application

This blog has helped me better understand the ways a team should function to maximize its potential, and seeing as I plan to work in the tech industry, I think it’s valuable to know this to help myself and my future team work to our potential.

recently read the article “Git Best Practices – A Guide to Version Control for Beginners” on freeCodeCamp.org. This piece offers a comprehensive introduction to Git, emphasizing essential practices for effective version control.

I chose this article because, as a newcomer to software process management, I wanted to understand how Git can enhance collaboration and efficiency in development projects. The article’s focus on best practices provided a clear roadmap for integrating Git into my workflow.

The content delves into fundamental Git concepts, such as initializing repositories, committing changes, and branching strategies. It underscores the importance of clear commit messages and regular repository maintenance. A key takeaway for me was the significance of atomic commits—ensuring each commit represents a single, logical change. This practice not only simplifies tracking changes but also aids in pinpointing issues during code reviews.

The article also highlights the role of branching in facilitating parallel development. Understanding how to create and manage branches allows for isolated feature development, reducing the risk of conflicts in the main codebase. This insight has reshaped my approach to project structuring, making me more confident in handling complex tasks.

Reflecting on the material, I’ve realized the transformative impact of adhering to Git best practices. They not only streamline the development process but also foster better team collaboration. Moving forward, I plan to implement these practices diligently, aiming to contribute more effectively to projects and enhance overall code quality.
