Week-10 Post

This podcast by All The Code discusses the use of GitHub and GitLab APIs for managing software development projects. The host of the podcast conveyed his disdain for GitHub’s API when he was involved in a project that utilized GitHub to share images and video links. Users had to request access to the repository in order to access the content, which the speaker did not like. He emphasized that requesting access on GitHub isn’t user friendly to someone who isn’t experienced with the site. When the hosts talked about GitLab, they described the platform as “amazing” and its ability to do “wonderful stuff”. Additionally, The speakers compared both GitHub and GitLab’s documentation and found GitLab to be the all around better platform documentation wise. Lastly, the podcast hosts argue that GitHub is ideal for large companies as GitLab is suited for smaller companies/teams. I chose this specific podcast because I have worked with both GitHub and GitLab in this class and can’t seem to prefer one over the other. I will say that I was more comfortable with traversing GitHub compared to GitLab. Although GitLab is considered to be easier to navigate, I often find myself struggling to access projects and repositories in different groups within GitLab. I’m hoping as time comes, I will get more comfortable with navigating the platform. This podcast has changed my view on GitLab, knowing that GitLab is more user friendly with documentation is extremely important to consider when choosing which platform to use mainly. Of course, companies will expect their teams to use the same platform to prevent any conversion issues. Having solid documentation in your software development projects is vital so new developers/users can easily understand the project and its goal. Going forward with this information, I will experiment with the various features GitLab has to offer regarding documentation. For example, GitLab has a feature called GitLab Flavored Markdown (GLFM) which gives you the ability to render certain text with a style. GitLab Flavored Markdown allows you the change the color of text, add emojis, create detailed lists, and more.

Git and Game Development

     A subject that has always been near and dear to my heart is video games. Throughout my life I have always been deeply enamored with games and the process of their creation, from the intricacies of 3d modeling to the various game engines in use. Despite that, I would not say I am an expert in modern game development by any means. As my classes have progressed however, I have begun to understand more about the inner workings of software development and how teams are managed. This led me to investigate how game developers use these tools to manage projects and keep everything orderly. After doing some research, I found that many game engines are compatible with git and have no issue being stored on GitHub. Not only that but prominent game engines like Unreal Engine even have their source code up on GitHub, available for anyone to fork and clone. This was done to allow developers to modify the game engine itself, for whatever purposes they need. Godot is a free open-source engine that uses the MIT license and is also entirely up on GitHub. Of course, even if an engine does not have their code on GitHub or Gitlab that does not mean you cannot just host your code in an online repository. Thanks to what I have learned this semester, I can now make use of GitHub in the creation of repositories for any game projects I have. 

  It is not enough to learn about how game developers make use of git, project management is also a vital tool for game development. In terms of project frameworks, agile methodologies have seen widespread use within various industries, including the video game industry. Scrum is the most prominent of these methodologies and has been adopted by various companies. Due to the nature of video game development, there is a greater need for cross-disciplined teams comprised of developers versed in various skills. Game development can be effectively chopped up into tasks that fit nicely into each increment, for the medium itself necessitates a functioning step by step pipeline. Level designers cannot do anything without the assets created by artists and so on and so forth. The first couple sprints would work on creating functional assets like 3D models, textures, and game mechanics. The goal of each subsequent sprint would be to create a functional game section by section. I hope to one day make use of scrum and help create a game of my own.

Week 10 choosing an Open Source license

Over the past few weeks, we have been learning about licensing and the different kinds and uses they all have. We have now even started to choose/implement our own inside our own group projects. In addition, the homework we did had to do with licenses.  With so much already learned about licensing why would I gain from learning more about this topic? Sometimes when doing work in a time-constrained environment you don’t absorb all the information and with this being at my own pace I can review and learn new things I may have missed or not seen. 

With all the information we have been learning about licenses you may think it’s hard to retain all this information but one key thing you should remember is that licenses can be split up into two categories copyleft licenses or permissive licenses. A copyleft license basically makes the modified open-source work be released under the same license. The original copyleft license is GPL (general public license) which means that any project using GPL must be open source as well. Another example of a copyleft license is LGPL (Lesser General Public License) is considered much more commercial-friendly than GPL because it has no requirements for software that only uses the license project. On the other side of the spectrum, there are permissive licenses that don’t put restrictions on people using a project. An example of a permissive license would be MIT which allows users to do whatever they want except they must contain the copyright statement and the original license. Even with all the possible choices for a license, you must ask yourself what your project needs and look at examples if ever stuck. Also, don’t forget to choose a license because this will cause much more harm you will restrict your code from being used by anyone except yourself.  

Reading this article allowed me to see licenses in a more simple and enclosed way instead of being bombarded with multiple different licenses. Being able to split up licenses into categories in a concise way allowed me to see how licenses weren’t as complicated as I thought. Now when I am shown a license I can automatically put it in a category and understand the major functions of what restrictions may it have. Also, it is easier to know the purpose of my project and be able to pinpoint the exact license I may need. I know I make it sound simple but the process in itself can be overwhelming having a foundation can make the process not as nerve-racking.

Kubernetes Clusters: What they are, and why it may become the most in-demand skill in the 2020’s

To say that the use of containers has revolutionized how applications are designed and deployed would be an understatement. Gone are the days of applications being run on physical servers, as due to the issues with resource management, the alternative of using virtual machines to run multiple applications on a single CPU provides vastly more flexibility to developers. One downside of virtualization, however, is that these virtual machines are considered rather “heavy.” Each VM is a fully-functional machine, running a full OS in addition to whatever virtualized hardware is added on. In environments where each server’s CPU may have multiple virtual machines running, the same issue occurs; high resource usage.

To solve this problem, the use of containerized software has become common. Containers share the same OS instance as the host machine, as opposed to a VM, which has an entirely separate OS. This leads to a multitude of benefits, such as reducing image storage size. While a VM uses images multiple gigabytes large, container images are much smaller; often measured in megabytes. Additionally, containers are entirely independent, meaning they are much more easily portable, which leads to faster and easier deployment.

One major drawback to containers is the upkeep. Containers must have a specific amount of resources added to them, such as memory usage, while also, like anything else, can fail and need repair.

Enter Kubernetes; an open source platform designed to automatically conduct these maintenance tasks. Kubernetes uses clusters as the basis for their infrastructure, each containing nodes which run and manage the application. Control plane nodes manage scheduling, the API server, and other services. Worker nodes are where applications are actually run, with larger applications using more worker nodes than smaller ones.

If such a platform is so valuable, why are so many positions left unfilled? Because jobs working with Kubernetes are hard.

On the one hand, developing and maintaining applications with Kubernetes requires experienced engineers, and time. The nature of the environment simply demands developers have the knowledge and experience to implement it.

On the other hand, because Kubernetes is such a new technology, the field is rapidly evolving, requiring developers to evolve along with it. Each change requires testing and optimization, as well as programmers needing to continue to broaden their expertise.

Why is this problematic? In addition to creating a work environment prone to causing burnout among employees, engineers working in this field can outgrow their positions quickly. As they gain more experience and widen their skillset, many move on to positions that offer higher pay. According to Forbes, Kubernetes engineers spend an average of just 18 months in their positions before moving on.

This creates a cycle; engineers are hired to work on Kubernetes platforms, hold their positions for a short while, and either due to the intense workload, higher paying positions, or a mix of both, move on. This leaves an opening in their previous position, which must be filled by a new hire. Rinse and repeat.

Software Licensing

Software licensing is everywhere in the technical world, and for good reason. Without it, our current copyright laws would make it impossible to distribute software in ways that are both beneficial for the user and developer. Fernando Galano does a great job explaining what software licenses are and how they are used in his blog, “Understanding Software Licensing” (https://www.bairesdev.com/blog/understanding-software-licensing/).

What is a Software License?

In short, a software license is a legal contract between the developers of a software and its users. We, as users, have all been asked to check a box in the past agreeing that we have read and agreed to the terms and conditions.  These terms and conditions are called an end-user license agreement (EULA) and spell out the rights and liabilities of both the user and software provider.

What Does a Software License Cover?

EULAs are typically large documents that contain information on how the end-user may install, modify, copy, or distribute the software. These are the more common things to find, however, they are not limited to this.  EULAs may also specify time of use, pricing, and support. These documents are usually very large because of the extent of topics they cover. 

Different Software Licenses:

Public Domain License:

  • Software under a public domain license can be used, modified and distributed freely with little to no restrictions. Not all free software has a public domain license.

Copyleft License:

  • Software under a copyleft license may be modified and distributed providing the modified software is distributed under the same terms as the source code.

GNU Lesser General Public License:

  • Software under a GNU Lesser General Public License may have its code altered or used in other software and distributed under a different license. 

Permissive License:

  • Permissive licenses are open sources licenses with requirements on how users may modify, reproduce, or distribute. This gives developers control over what happens to their code.

Proprietary Software License:

  • Typically used for commercial software. Provides the greatest restrictions for users and typically are not allowed to modify, copy, or distribute. 

Using Software Licensing Moving Forward

Quoting the first line from the blog, “Your product could be phenomenal, but before you deploy it, you need to grapple with the legalities surrounding the distribution and usage of your software.” (Fernando Galano).  It is clear to see that without a proper grasp of how software licensing works, development of software can only get so far. The next step in being able to distribute work is to license it properly for its intended use.

11/18 – Keeping the ball rolling.

So, since the end of the semester is coming up, I should be posting weekly for the near future, so stay tuned for a lot from me! With this week of work, I have two topics I wanted to discuss, both related to each class I’m taking with Professor Wurst.

Firstly, on the Software Process Management side, I wanted to discuss how we’re using Scrum, and the way it’s set up. We’re using GitLab’s issue boards, dividing them amongst where they currently are in The Sprint, with stuff like the Issue Backlog, In Process, Needs Review, Finished, and so on so forth.

This setup reminded me a hell of a lot of Trello, a website/service I’ve been using for years now! And what’s funny is that I even mentioned this in class once, and the Professor said he used to as well for Scrum. My setup is quite different compared to the setup we have on GitLab, however, it still uses a similar Scrum/Kanban-esque setup.

Here’s the two boards I mainly use, one for School, and one for Commission work, as I freelance in art. With my Comm board, it is a bit more simpler, having using tags within lists as opposed to using a list per tag. As for my schoolwork board, it’s simply just listed with each course I’m taking and items of work I need to finish. It’s a very good tool, and I highly suggest it to anyone looking to utilize Scrum or even need a good tool to organize things.

Check it out here! https://trello.com/

As for the Software Design, I was curious what kind of file the .json’s we were using were. We have been using them to store data about students and members of the modified version of LibreFoodPantry’s backend. I’ve seen them used before many times in my times modding games before, usually they store data for configuration files.

So, to learn more, I found this blog from HubSpot: https://blog.hubspot.com/website/json-files, and honestly I think I get it a bit more now. They’re simply data storage files, able to store comma seperated values, objects, and arrays. They also support multiple data types, like integer, boolean, and strings.

So putting that into the context of configuration files, like for settings in games, it makes sense why they are used, due to integer and boolean values. If an option for a game has an on/off choice, a boolean data value to hold that information would make sense, as “true” would be on, and “false” would be off. As for how integers would be used, say you want to store the value of the volume the user wants while playing the game, that can be stored as an integer from 0-100.

All in all, it’s really interesting to learn more about filetypes I don’t know too much about, and I should look into more and how they are written, like .obj, .html, and .ini.
