The Real Value of Open Source Software

Open source software is so valuable to society, but how would that value be translated into currency? About 96% of all commercial companies contain code that originates from an open source software (OSS). But according to new articles and papers being written on the subject the amount that these free softwares save these companies is a lot larger than people originally expected. Without it, firms would pay an estimated 3.5 times more to create the software and platforms that run their entire business which in total would be around $8.8 trillion in total. Due to this many companies make sure to express how important it is to hire people who have experience with open source software as it is the backbone of companies. The authors  of the article calculated the estimated value of open source software by combining data from The Census II of Free and Open Source Software and BuiltWith, which is a database that takes millions of websites and identifies technologies they use. To estimate the cost of recreating these open source projects from scratch, the researchers analyzed the number of lines of code in each project and used the COCOMO II cost estimation model, that predicts development effort and expense based on the size of the code and how complex the code is. They then adjusted these amounts using regional wage data to show how much it would cost in labor throughout the world. This allowed them to estimate that both the cost it would take to replace all of the software would be around $4.2 billion and the total value of open source software being used in the world is almost $8.8 trillion. The reason I used this specific article was because of our current discussions of open source software and how important it is to not only people who are in tech, but also people who are less fortunate and need the resources that this free software gives them. So to see an article that explains what the commercial value this software provides around the world and how much it is actually worth is shocking and goes along perfectly with the importance we saw of it in class. The article itself was very interesting to read about as well. To think about how much it would actually cost to create this software is absurd and really opens my eyes as to how large it actually is. Before reading I believed that it was helpful, but I didn’t know the importance it has in actual companies. As well as how helpful it is to have experience in open source software when it comes to jobs as well. I am definitely going to do more research into different software and hopefully it helps me with my future career.

Beginners guide to Software Licensing

by Petraq Mele

Hello to all reading this blog today, the topic this time is software licensing and its importance in the development of software. I began researching about it as I had very limited knowledge about it and its importance. I ended up reading a blog written by an experienced developer named Rahul Awati titled “What is a software license?”, and I ended up learning quite a lot about the importance of this topic.

Various icons representing software licensing concepts and principles.

So what exactly is Software Licensing?

Practically speaking software licensing is a document that provides legally binding guidelines for the use and distribution of software. You can think of all software licenses as essentially a contract between the developer(s) and its user(s). It outlines the rights between these two parties for a piece of software along with the terms and conditions. All software comes with a license/product key which is important for identity & verification.

Its fairly simple to license software. Legally you already have, as the author of your software, a natural right recognized by copyright laws. If you want to add anything else to a license many developers but it in a text file within their software packages. Some sources like choosealicense.com or www.gnu.org are useful for finding templates or examples.

Some things that you may find included in a license are:
– Basic information(Names, Contacts, Address)
– Charges
– Duration
– Distribution rules
– Terms of service/cancellation
– Governing law
– Maintenance
– Etc.

Types of software licenses:

A visual representation of the 5 approaches to software licensing, ranging from public domain to proprietary licenses.

A few software licenses include:
– Free and open source(FOSS): Allow anyone to use software, and even to study, change or copy its source code.
– Proprietary: Often referred to as “closed source”, this software has strict rules towards obtainability & alterations.
– Public domain: Like open source but should be cautiously used by businesses as it might not meet their expectations.
– Lesser general public: Developers can link to open source libraries within their software and use any licensing type for the code.
– Permissive: Allows users to modify & distribute a piece of open source software but with some requirements for them as well as preservation of license notices, copyrights, or trademarks.
– Copyleft: Open source as long as they make the modifications freely available. New products containing old code with a copyleft license must comply with the restrictions laid out in the old code’s license.

Why do we need licenses?

Licenses are important because of all the reasons we have outlined earlier. It helps protect both the developer & the user.

A few beneficial protections for developers include: Protection of intellectual property, ensuring control over their creation, limiting liability, & monetization of products.

As for the users, the benefits are: Prevents misuse/unintentional mistakes causing damage, protect from infringement claims/ liability, create positive relationship with other developers/users/vendors, & establish clear parameters of how many licenses an organization needs.

Based on these few protections you can see the importance of licensing. It keeps a professional structure towards the spread of software and encourages a just environment.

Final thoughts

Understanding software licensing is something each software developer should take the time to learn whether for their own personal gains, or as a way to safely use/produce software. Aside from the legal aspect of it, licensing is about respecting a developer and their work. As I mentioned earlier I want to give credit to Rahuls’ amazing blog as inspiration for mine. Be sure to read his blog if you want more insight on this topic.

Blog Post for Quarter 1

October 5th, 2025

Recently, I’ve been working on using Git. This came in the form of using a little bit of GitHub, a little bit of GitLab, and the textbook made to help instruct me on how to use them. I began to learn the basics of repositories, and how to make edits and pull requests.

For example, I am now able to create a fork from a repository, create a remote origin, a clone of that onto my local device, make edits using Visual Studio Code, stage those edits, commit those edits, push those edits back to my remote origin, then establish a pull request. And a little bit more. So far, this Quarter of my class has been pretty interesting. I will note how the public changes and such are very interesting to me. I don’t usually like being in public places often because I assume I should be competent before doing anything in public, but oh well.

For the blog post I selected, I wanted to know just a smidge more about Git, since I was learning about it. (This will be linked below at the bottom of this post.) It mostly discusses the future plans for Git and potential for AI.

Honestly, there isn’t much for me to really do from this. I just note how AI appears to be Git stuff I currently use, so that’s mildly interesting. Though, I found it interesting that Git, much like I, is currently developing. It’s fun to think about how I learn and improve as a person that other things in the world are doing the same. While they are wildly different contexts, I find it cool. Everything is always changing and such. Even as I learn, I make notes that aren’t in the textbook to myself. Git will probably always get things added by various different people as well.

It encourages and intimidates me in some way. It’s very cool that by the time I “get caught up” it’ll be better than what I’m currently using, but at the same time, what if everything I learned becomes redundant? Though, for me, I was always a person to enjoy experiences, and I never really liked the idea of a limit. If anything, it is just more “fun” for me. There’s more to learn and I’ll never be caught up. My experiences will lead to my growth, so when the time comes, I’ll be much more suited to using the new tools that arrive.

Reflection on “Coding Standards and Guidelines”

by: Queenstar Kyere Gyamfi

The GeeksforGeeks article “Coding Standards and Guidelines” highlights the importance of writing code that is clean and consistent. It also underlines the need for code that is easy to understand. It explains that coding standards are a set of rules and conventions that help developers maintain clarity and quality across a project. These standards cover areas such as naming conventions, indentation, code structure, comments, and documentation. The article emphasizes that following standards is not about limiting creativity. It is about making sure that everyone working on a project can easily read and maintain the code. It also points out that coding guidelines help prevent errors. They make debugging easier. They ensure that software projects remain manageable as they grow.

I chose this resource because I’ve noticed how quickly group projects can become messy. Each person having a different coding style contributes to this messiness. I’ve always cared about writing code that works. I’ve started realizing that how the code looks and reads is just as important. This is especially true in team environments. This article stood out to me because it clearly explained the purpose behind coding standards.

One key lesson I learned from this article is that consistency builds trust among developers. When everyone follows the same structure, it becomes easier to understand, review, and modify code written by others. The article also reinforced the idea that good code should be self-explanatory. For example, meaningful variable names like totalPrice or userCount communicate intent better than short, unclear ones like x or val. I also learned how proper indentation and spacing make code more readable and reduce the risk of logic errors that come from misaligned statements or missing braces.

Reading this resource made me reflect on my own coding habits. Sometimes, when I’m rushing to finish an assignment, I skip comments or mix naming styles without thinking about how confusing it might be later. Now, I see that writing clean code is an investment as it saves time when debugging and helps others understand what I meant. I also want to use tools like linters and formatters to automatically enforce standards in my projects.

Overall, this article helped me understand that coding standards are not about perfection but they are about communication. Clean, organized code reflects professionalism and respect for the next person who will read it. It reminded me that in software process management, technical skills and teamwork go hand in hand. Writing code that others can easily follow is one of the best ways to contribute to a project’s long-term success.

CS348-01: First Blog

The First Blog

Software process models are definitely something that I feel like as a student taking CS348: Software Process Management should have an idea or an understanding of. They are frameworks that define the sequence of events like activities, tasks, and the deliverables that are required to develop software. “These models act as a roadmap, providing a step-by-step guide for software development teams.”

And there are quite a few key components to software process models that are essential for successful software development. Requirements gathering and analysis, design and architecture, coding and implementation, testing and quality assurance, and finally, deployment and maintenance are these essential components.

“Design and architecture focus on creating a blueprint for the software. It involves designing the overall structure, defining the modules and components, and establishing their relationships. This phase lays the groundwork for the coding and implementation phase. Coding and implementation are where the actual development takes place. Developers write the code based on the design specifications, bringing the software to life. This phase requires attention to detail and adherence to coding standards to ensure a high-quality end product. Testing and quality assurance are crucial to ensure that the software meets the desired quality standards. This phase involves various testing techniques, such as unit testing, integration testing, and system testing, to identify and fix any bugs or issues. Deployment and maintenance involve releasing the software to the end-users and providing ongoing support. This phase includes activities like installation, configuration, and user training.”

In simple words: design and architecture is the planning stage where it draws up blueprints to figure out the big picture before the actual building. Coding and implementation is the building stage where the developers write the code using the plan made as a guide, to make it neat and make sure the code is correct for a good final product. Testing and quality assurance is the checking stage, they run many different tests to ensure that code is working from individual parts to groups of parts and then the whole system. And finally, deployment and maintenance is the launch and support stage where the team can get the finished product out to the users and keep it running well.
And these stages are used in many different types of models. The waterfall model– which is a linear, sequential approach– to the agile model where it has flexibility and adaptability when it comes to planning– and to the iterative model that focuses on incremental development.

What the “Grug Brained Developer” Teaches Us About Software Process Managment

Link: The Grug Brained Developer

For my self-directed professional development blog, I chose to read The Grug Brained Developer by Carson Gross, who founded the Hypermedia Research Group at Montana State. On the website, a free, digital version of his book, Gross manages to distill complex software wisdom into simple, almost primitive advice. Written like a caveman developer, it explores core ideas and fundamentals of coding and communication in a way that’s both funny and accurate.

The article’s central theme is simplicity. Grug constantly emphasizes avoiding unnecessary complexity in both design and process. He warns against over-engineering, over-abstracting, and blindly following trends—ideas that directly connect to what we’ve discussed in CS-348 about software process management principles like iterative improvement, communication, and agile adaptability. In short, Grug argues that most of software development isn’t about doing more, but about doing less and doing it better.

I selected this resource because it presents timeless software management lessons through a format that’s approachable and memorable. Rather than reading another dry technical essay on process maturity or workflow optimization, this post made me think deeply about how simplicity affects process management. In a course where we analyze methodologies like Scrum and Kanban, it’s easy to lose sight of the human side of software development—how teams actually think, communicate, and make decisions. The Grug Brain post brings that perspective back.

What stood out to me most was the section where Grug says, “If no can understand code, no one can fix. Then bug live forever.” This humorous line perfectly encapsulates why clear process and communication are essential to good software engineering. It aligns with our course’s emphasis on maintainability and collaboration. A well-defined process isn’t just bureaucracy—it’s what ensures that projects remain sustainable when team members change or systems evolve.

I also learned how simplicity ties into continuous improvement. In agile environments, each sprint is a chance to refine not just code, but the process itself. Grug’s idea that “small simple thing better than big clever thing” echoes this perfectly: effective software process management focuses on clarity, iteration, and team alignment over cleverness or premature optimization.

Reflecting on this, I realized that I often over complicate my own projects—whether by designing too many abstractions or worrying too much about tools instead of workflow. Going forward, I plan to apply Grug’s philosophy by prioritizing clarity in both my code and my project management habits. That means writing simpler documentation, refining processes only when necessary, and valuing human understanding above technical elegance.

In summary, The Grug Brained Developer provides a surprisingly profound take on process management: simplicity and communication are the real foundations of sustainable software development. I’ll carry this mindset into my future work, reminding myself that even in a world of complex methodologies, sometimes the best process is the simplest one.

Navigating UML

I read the article Navigating Complex UML Diagrams: Tips and Tricks for Developers. This gives a lot of insights into practical strategies that you can use to maintain and understand UML Diagrams, specifically larger ones. This article focused on UML stereotypes and the organization of diagrams. UML stereotypes are an extension of standard UML elements. Developers use these to add more specific definitions. Stereotypes allow you to label a class, an interface, or a service component, etc.  This adds a layer to help the diagram effectively communicate the structure and intention of the code. The article also suggested using color coding for groups to emphasize relationships. Keeping your layout styles and naming conventions consistent and clear is also very important. UML allows architects and developers to show both the structure and behavior. These diagrams can be extremely important in a collaborative environment. Having a clear UML diagram would keep everyone on the same page and help avoid having to rework code. UML can also help show off early architectural flaws before you put time into a project. Since you can visualize the relations, dependencies, coupling, and flow before any of it is implemented, you can prevent issues. Many of my issues with coding come from the planning aspect of it. I plan on continuing to get better at making these diagrams because I feel they can have a very positive impact on my coding. It can be difficult to picture how different parts of a program will come together, and it can become very overwhelming very quickly. It’s also interesting how different UML diagrams serve unique purposes. Visual Paradigms, UML Practice Guide, says structural diagrams like class, component, and package diagrams are good for showing how different parts of a system fit together, while behavioral diagrams like sequence and activity show how things interact over time. With this separation, a developer can handle one part of the design at a time, instead of trying to understand everything at once. There also exist Artificial intelligence tools that can support UML. PlantText AI, Visual Paradigm Smart Assistant, and PlantText AI can help save time and reduce manual errors. In the future, I’m curious if this is something that will still be manually done, or if AI will spread deep into this too. I can’t see these diagrams ever losing importance, but I do question if humans are going to be directly making these in the future. Either way,  I am excited to practice these techniques and implement UML diagrams into my planning.

VCS Safety Net: Protecting Code and Empowering Collaboration

For this quarter’s blog post, I chose to deepen my understanding of Version Control systems (VCS), specifically how tools like Git and platforms like GitHub and GitLab function within the software development lifecycle. Learning new tools and techniques takes continued practice, and learning Git was no different. My goal with this content is to strengthen my knowledge of the core concepts and purpose behind these vital tools, which is what my Software Process Management course is currently emphasizing working with and practicing.

I focused on a website from GitHub itself, which explained what version control is. I chose this resource because it provides a foundational explanation of VCS, its types, and current popular tools. This article, “What is Version Control?”, defines VCS as systems that give members working on the same project complete visibility into the history of the code, and centralize all members’ work. It describes how Distributed Version Control Systems (DVCS), like Git, are essential for software development. It explains key concepts including the ability to track every change, work independently, propose code additions, and safely integrate changes while preventing conflicts. In other words, the process of commits, branching, pull requests, and merging; all fundamental processes we are focusing on in my course.

Before this course, and diving into resources, my understanding of Git was minimal. I gained a much deeper grasp of how VCS tools are both seen as a safety net and a coordination tool. Branching is one of the most important steps within the software development process, as it allows a team (of however many or little) to work synchronously on a project without fear of overwriting or corrupting the main code. Allowing team members to work independently, cohesively, and in a time-efficient manner; while also being able to access and review modifications made by other members via accessing their branch of the project. 

Although all of the information is important, the section on best practices particularly resonated with me. While working with Git, we are encouraged to save changes in small increments, making sure to write a helpful commit message, rather than making large changes and saving at the end. Seeing this best practice emphasized in the article reinforced its importance. Using this technique significantly reduces conflicts and makes debugging errors and explaining changes much simpler. 

I expect that I will continue using Git throughout my professional career, and I plan to apply this understanding immediately as I continue working with Git in class. My goal is to use this knowledge and helpful techniques to practice improving my execution and workflow. I will prioritize working in small increments, committing those small changes, and reviewing my changes to ensure my progress is meeting expectations and to also contribute to the team’s collaboration.

UML Diagrams…Why?

For this quarter’s blog post, I chose to deepen my understanding of Unified Modeling Language (UML) Diagrams, which directly relates to current coursework in my Software Construction, Design, and Architecture class of translating between code and visual diagrams (i.e., UML class and sequence). Initially, I found both processes overwhelming and questioned the purpose of using such diagrams instead of simply reviewing the source code step-by-step. To overcome this hurdle, I looked at several resources, but I will focus on Miro’s comprehensive guide, “The Ultimate Guide to UML Diagrams,” which provided much needed clarity on the concept of UML Diagrams.

This guide offers an excellent foundational overview, and emphasizes UML Diagrams as the commonly used and encouraged visual language in software development. It identifies the 14 types of diagrams and categorizes them as either Structural or Behavioral. Structural diagrams are used to define the components of the code, while Behavioral diagrams are used to examine how the code operates over time.

A key part of this research involved understanding the drawbacks of using UML diagrams. With my own initial experience being overwhelming, complex, and tedious; it validated the discourse surrounding the love-hate relationship with UML in the software development field. Disadvantages often centered on the process being time-consuming, complex, overwhelming, and potentially ambiguous, especially as projects grow or when team members and stakeholders are not aware of coding and diagram literacy. While arguments exist for making these diagrams optional, I understand that this is a necessary and helpful step in professional practice. 

This and other resources consistently emphasize one core objective: UML Diagrams are primarily communication tools. While recognizing their flexibility, standardization, and (often) simplicity, their greatest benefit is serving as a visual aid. They create a working summary of a program/code that allows other team members and stakeholders, who may have limited time and/or specific knowledge, to look through hundreds of lines of code, to quickly grasp the architecture and operational flow.

I also learned that the perceived disadvantages of UML are the trade-off required for effective team collaboration and risk mitigation. When working through class activities and homework, working with smaller codes, I experienced some of the limitations. I fully understand how a program with 50+ classes would be completely overwhelming and time-consuming to look through and explain without an established visual reference. My personal practice of using UML class and sequence diagrams showed me the tediousness of detailing every code component, but also the value of creating and having a visual summary of the code’s building blocks.

In my future practice, I intend to apply this knowledge by creating diagrams to help me summarize the code. Whether working on class activities, homework, personal projects, and/or within a development team; I will use UML diagrams to practice summarizing and communicating code as if I were speaking with a team and/or non-technical stakeholders. Ultimately, a diagram is easier to critique and comprehend than 500+ lines of unread code spread across multiple files.

Blog & Podcast Discovery – Software Architecture

Resource Selected:
“Patterns of Legacy Displacement” by Ian Cartwright, Rob Horn, and James Lewis
Published on Martin Fowler’s Software Architecture site
https://martinfowler.com/architecture/

Summary of the Resource

This article explores the practical challenges of replacing legacy systems in large-scale organizations. The authors introduce the concept of the “legacy replacement treadmill,” a cycle in which enterprises launch extensive modernization efforts that often stall or fail before meaningful progress is made. The authors argue that the core issues extend beyond outdated technology to include organizational and leadership shortcomings. To address these challenges, they recommend setting clear goals, delivering improvements in small, manageable increments, and avoiding “big-bang” system rewrites which typically lead to failure. Instead, they propose a more sustainable approach: gradually isolating and updating parts of the legacy system, delivering functional components, and slowly retiring the outdated codebase.

Why I Chose This Resource

I selected this article because it directly relates to key principles we’ve discussed in our software design and architecture course, such as maintainability, technical debt, and scalable architecture. Rather than just presenting theory, the article demonstrates real-world consequences when these principles are overlooked. Additionally, I’ve observed similar patterns on a smaller scale during team projects, where the instinct to start from scratch often feels easier than improving existing code. This resource provides a practical, realistic alternative to that approach.

Reflection and Key Takeaways

The most impactful lesson for me is that modernization should not be seen as a rapid technical overhaul but as a long-term, structured effort. The authors emphasize defining clear outcomes before writing any code a concept that shifted my perspective. In future projects, I aim to prioritize measurable objectives over vague goals like “make it better.”

Another important insight is the risk of pursuing feature parity with legacy systems. Attempting to replicate every existing feature can hinder innovation and slow down progress.

The article also deepened my understanding of how human factors such as team habits, organizational power structures, and internal priorities can influence the success or failure of architectural changes. Even the best-designed technical solutions will struggle to succeed without cultural alignment and support for gradual transformation.

Moving forward, I intend to apply this mindset to legacy code by introducing incremental, testable changes that improve the system’s architecture over time. This approach may be slower, but it is ultimately more effective and sustainable.
