Introduction

The blog, “A Short Guide to Open Source Licenses,”by David Skaife, helps us understand the often confusing world of open source licenses. Let’s break down the key points to make sense of why these licenses matter in the world of computer software.

Understanding Open Source Licenses

Open-source licenses are like rules for sharing computer code. They tell us how we can use, share, and change the source code. These rules help protect the original creators and make it easier for others to use the code without asking for permission each time.

Clearing up Myths: Public Repositories and Licensing

Skaife talks about a common misunderstanding of just putting code on a public platform, like GitHub, doesn’t automatically make it open source. Without a clear set of rules (license) with the code, it’s still protected by copyright, and others can’t freely use or change it. So, it’s crucial to attach a license if you want others to use your code.

Making Sense of Licenses

Skaife acknowledges that there are many licenses, but he suggests focusing on a few popular ones. He also mentions the Open Source Initiative (OSI), which approves licenses, making it easier for us to choose from reliable options.

License Types: Strict vs. Flexible

There are two main types of licenses – strict (copyleft) and flexible. Strict licenses say that if you change the code, your new version must also follow the same rules. Flexible licenses are more relaxed, letting people use, change, and share the code more freely.

Exploring Five Common Licenses

There are five common licenses we might choose from:

1. MIT License: Simple and flexible, allowing changes with few conditions.
2. Apache License 2.0: Similar to MIT but a bit more complicated, addressing specific issues like trademark rights.
3. GNU General Public License (GPL) v2.0 and v3.0: Strict licenses, ensuring all changes follow the same rules, with v3.0 adding more details.
4. GNU Lesser General Public License (LGPL) v2.1 and v3.0: Less strict than GPL, allowing some exceptions for linking.
5. Berkeley Software Distribution (BSD) 2-clause and 3-clause variants: Flexible licenses, similar to MIT, with the 3-clause version having extra rules about using contributors’ names.

conclusion

Skaife’s guide helps us navigate open source licenses, making it easier to understand the rules for sharing and using computer code. With this knowledge, anyone working with open source software can feel more confident contributing, using, or creating, fostering a collaborative and innovative community. For those wanting more information, Skaife suggests checking out resources like the Open Source Initiative’s licenses pages and GitHub’s “choosealicence.com.”

This is just a quick summary of what I have been through in CS-343. It was a very impactful semester that taught me many new things. I believe what I enjoyed the most was working collaboratively in teams. I find myself always working better in a structured group and retaining information much better. Towards the end of the semester, when we started to work with APIs, specifically the backend/frontend, I noticed a big usage of JavaScript. The homeworks became a little more challenging because of this, and I am going to use my break to get a crash course in JS. I also am working on a personal project where I will soon be implementing a frontend GUI, so the timing works out great.

I also cannot wait for the capstone class next semester as the whole idea behind the class just sounds perfect. I am a very hands-on guy, so getting to finally work on an actual project for a semester with a team and implementing what we learned will be a learning experience. Also, a great way to practice for internships and job opportunities for the future.

Earlier in the semester, we discussed licenses and copyright in regards to our code and documentation. I’ve wanted to write a post on licenses, but finding a post that did more than describe the definitions and uses of licenses was difficult. Luckily, I have found a blog that describes software license management, the best practices, and some drawbacks when managing licenses. From those sections, I want to highlight the parts that felt the most important. The blog is called, “Seven Best Practices for Managing Software Licenses” by Ibrahim Ogunbiyi, a data scientist and IT support specialist.

The post starts off with defining software license management as the process of controlling, tracking, auditing, and managing the use of software in an organization. They highlight the importance of using SLM in many ways, but the one that stood out to me was to ensure the software is secure and has no malicious code. If there is no liability in the rights listed by the license or the lack of one, I can imagine how it would be important to sift through each one to ensure the code is safe to use. Another one that felt important was keeping track of software due dates. Having your team or company rely on access to software only to have it pulled from you could be expensive and time wasting. If you fail to stop after your access is revoked, you could be held liable and sued.

The potential setbacks of SLM were the cost, complexity, and compliance risk. In an organization or large company dealing with a myriad of different license types and potentially using them in combination with each other, I can see how those issues could come up.

The best practices discussed in the post that I found most important were documentation and training. Any issues that arise when dealing with license issues would be incredibly hard to fix if you cannot find relevant information. Keep track of everything, within reason. I have worked in a company that had one person in our location who was fully trained to use the company’s software. She was berated with questions about how it worked without every employee getting a full understanding of the system. She was the linchpin. After she left, so many things fell through the cracks and I can only imagine how detrimental that could be when dealing with licenses. Making sure everyone is on the same page with a full understanding of how licenses work will save companies a lot of time and money.

After reading this post, I felt like this would be especially helpful for people starting their own company. Understanding the complexities and importance of software development can only help in the future. Although I do not feel like I will be making decisions on implementing a software management system anytime soon, I will still keep what I learned in mind when dealing with licenses.

Recently our class discussed inclusive language and delved into tools that are able to root out non-inclusive language. I tried to find an article or blog that gives a set of examples to watch out for. I found a blog post that gives guidelines, examples of non-inclusive language, and provides examples of how companies are adapting to make their language more inclusive. The blog post is called, “Inclusive Language in Technology” by Barathy Rangarajan, DreamWorks Animation.

            The blog post starts with giving a definition of inclusive language. It highlights the difficulty in changing language across repositories and identifying what is seen as non-inclusive language. Before diving into those offensive terms, they give four guidelines when writing code or documentation. These guidelines were: avoid using terms that have social history, avoid using idioms and jargons, write inclusive examples, and if you’re unsure, ask. I personally liked the inclusion of idioms and jargon being something to watch out for and how important it is to ask if you are unsure. Usually, idioms and jargon are just ingrained in the language we use based on where we are. Being aware of that when writing code or documentation for people who may not understand felt important. Understanding that these terms can be tricky to identify as non-inclusive, it’s important to ask those who might know more.

The post then gives a set of terms deemed non-inclusive, organized by different categories. These categories were, socially charged, gendered, ableist, ageist, and violent language.  I won’t get into detail about each, but I recommend you take a look to familiarize yourself with the terms and alternatives. There were some terms I was not aware of.  

The final portion of the article is the how companies have made changes to be more inclusive. They described how Autodesk, DreamWorks, and Sony pictures are addressing non-inclusive language. Some involve hiring based off race and gender, promoting resource groups, and setting a baseline initiative to produce inclusive code in the future and update older code. In one of my previous posts, I talked about setting ground rules that the team can agree on when conducting ourselves during development and discussions. I feel this is also relevant when it comes to inclusive language.

The blog post shed some light on the best practices and popular terms used when addressing inclusive language. In the future I will strive to be self-aware about how I write, ask question when I don’t know, and use what I’ve learned in day-to-day interactions along with writing code.

What is a Dev Container?

A Dev Container, or development container, encapsulates a complete development environment accessible through Secure Shell (SSH) in your preferred Integrated Development Environment (IDE). It overcomes workflow impediments such as low performance and limited bandwidth by providing an isolated environment with standardized configuration stored in a .devcontainer.json file. This JSON file, structured with Comments (jsonc) metadata, allows customization for specific needs, such as adding tools or extensions.

Why Use it?

Addressing Setup Configuration Issues: Maintaining and managing local environments involves the use of various tools and configurations, leading to a cumbersome process. Standardizing this process with a unified approach can significantly save time and streamline setup configurations.

Standardizing Build Instructions of the Project: Documenting dependency upgrades and changes can be challenging. Utilizing code rather than extensive documentation simplifies the process, enabling anyone to ship without being hindered by the “it works on my machine” dilemma.

Ensuring Isolation of Development Environments: Developers often work on multiple projects simultaneously, each with its own complexities. Isolating environments prevents conflicts with other software on the host system, creating a clean, controlled space for development tasks.

Enabling Consistency Across Development Teams: Achieving portability across diverse teams is complicated by varying technologies and configurations. Implementing a standardized development environment ensures uniform configurations among team members, minimizing inconsistencies from individual machine differences.

Simplifying Onboarding and Training Processes: Quickly launching environments in isolation facilitates learning new languages or frameworks. This approach is particularly beneficial for onboarding and training processes, keeping machines clean and allowing for smooth presentations and workshops, where everyone can follow along without interruptions caused by missing tools or confusion mid-step.

Dev Containers in Real World Enviroment

1. Standardized Development Environments:
   • Dev Containers provide a standardized and reproducible development environment, ensuring that all team members work with the same configuration. This minimizes the “it works on my machine” issue and streamlines collaboration.
2. Setup Configuration Management:
   • Addressing setup configuration issues is simplified with Dev Containers. They help in managing dependencies, tools, and configurations uniformly, reducing the time and effort required for setting up development environments.
3. Version Control Integration:
   • Dev Container configurations are often stored in version control systems (e.g., Git), ensuring that the development environment is versioned along with the code. This enhances collaboration and makes it easier for team members to switch between branches or versions seamlessly.

Personal Experience

Dev Containers are something I have recently just learned about, and I feel like the need for them is understated. The overall idea behind such a tool is to create a simple and consistent environment for a team to work in. Anytime I work on a project, I stress the need for one as it eliminates many common problems teams face in the early stages of development. I also believe that when I start my professional journey, I will find these containers to be more standardized within the teams I work with.

After reflecting on the previous blog that I had written about coding, I pondered about what would happen if I were to work with software, and I immediately wanted to consider something about a software’s own making. For this blog, I decided to focus on Software Framework, which many programmers and organizations make great use of in the workforce. I took great interest in an article written by Tiago Monteiro, fittingly titled “What is a Software Framework?” It starts by giving the reader a simple concept where a man uses an axe to cut trees and then cuts wood to use for his fireplace for his family. When the chainsaw was introduced into this analogy, it related really well to programming, where you either start with fresh new code or make use of an existing framework done by another user to build your program. Reading more into the article, I found that there were advantages and disadvantages to using a software framework. While a framework is how anyone would start to form their own software, nobody has much freedom to alter the framework, limiting the use of a software framework to the functionality it was designed for.

I chose this article for my blog, because I believe that this article might help me in understanding a bit more about Software Engineering. Although the author of this article is a high-end Computer Engineer, his article could still give me an idea of what I should visualize when I start to learn more about designing software. A software has to have a framework to maintain functionality so it does not become inept, just as a computer will stop working if one of its most important parts either burns out like a wildfire or starts to malfunction upon reaching the end of its half-life.

My biggest takeaway from this article is that there are lots of software frameworks with many functionalities that are made useful in different manners.  Just as we try to create the framework to integrate smart machines into our appliances and everyday tools, we try to do the same with creating framework in our software as well.  We give life to our software the same way we try to create new computers, by giving it a spark of new and innovative programs for the greatest user and technological experience.
