Hello, Everyone. How are you guys doing?

This past week, I read some articles or news related to CS (Computer Science). I finally picked a topic that caught my attention; engineers create 3D-printed objects that sense how users interact. My reason for why and seeing how choosing this article is because it looks cool and relatable for Gamers to use any controller made of small rubber pieces. 

Short Summary: The researchers found a way to combine sensing capabilities into 3D printable structures made of constant cells, enabling designers to prototype interactive input devices quickly. Even, Formed a new method to 3D print mechanisms that detect how force applies to an object. Or The structures are made from a single piece of material so that they can be rapidly prototypes. Also, A designer could use this method to 3D print “interactive input devices,” as a joystick or a controller.

For accomplishing the goal, the researchers blended electrodes into structures made from metamaterials (The materials split into a grid of duplicating cells). Also, They designed editing software that benefits users develop these interactive devices.

First, The researchers need embedded electrodes because a grid of cells creates the metamaterial. That benefits from the user implement strength to a metamaterial object; cells can spread or reduce with few adjustable interiors. They also take advantage by creating “conductive shear cells,” adjustable cells with two opposing walls made from the conductive wire and two walls made from the non-conductive thread. Even, The conductive walls operate as terminals.

When a user implements strength to the metamaterial mechanism, it running a joystick grip or pressing the buttons on a controller. The conductive shear cells expand or decrease. Even, The distance and overlaying area between the opposing terminals changes. While using capacitive sensing, those adjustments can be measured and used to calculate the magnitude and direction of the applied forces and rotation and acceleration.

For demonstration, the researchers built a metamaterial joystick with four conductive shear cells embedded around the base of the handle in each direction. Also, moving around the joystick handle, the distance and area between the opposing conductive walls change to sense each applied force’s direction and magnitude. By learning how joystick users use strength, a designer could test different handles from shapes and sizes for people with faulty grip strength in specific ways.

Second, The researchers created a sensitivity controller designed to adapt to a user’s hand. When the user holds one of the flexible buttons, conductive shear cells within the structure can diminish and send sense input to a digital synthesizer. Also, This method could allow a designer to instantly create and tweak differently adjustable input devices for a computer.

Lastly, MetaSense, the 3D editor the researchers improved, enables this fast prototyping for a software solution. The users can manually combine into a metamaterial device or let the software automatically place the conductive shear cells in optimal locations. The researchers attempted to make MetaSense straightforward, but there are tests for printing such intricate structures.

The episode I’m commenting on is titled, “#163 Layla Porter was led to coding by her horse riding and personal coaching business”.

I have a partner who is into horseback riding and so I selected this episode because I thought I could potentially develop something that helps her.

In the podcast episode I listened to, we follow the software developer, Layla Porter. Layla first started learning programming with ActionScript and HTML when she was young. Most of Layla’s early learning was self-taught and for personal entertainment.

Layla starts her story by talking about the opportunity she received as an adult to ride horses full time. This was something Layla was excited about because she grew up riding horses her whole life.

While riding horses full time, she had friends at her work, who knew how to code and would teach her object oriented programming, Objective C, and Model View ViewModel.

Eventually, Layla decided to take a break from horseback riding and became a speciality personal trainer for horseback riders. She started her own gym called, “The Rider’s Gym” and made her own website to set up her business. At first, she had a pretty successful gym for several years coaching both professional and amateur horseback riders.

After some time though, her business started to become less profitable and she started reading books and teaching herself the skills needed for a career switch to become a developer.

Layla applied to many jobs and eventually landed an entry level coding position. She managed to work her way up to a senior engineer after some additional job switches, and by dedicating herself to learning as much as she can in the field.

Currently, Layla still works in software development and she is an advocate for people from all backgrounds becoming developers if they are willing to put in the time and effort to learn it.

While my partner is not likely to start up her own fitness/horseback riding business soon, one of the most interesting things about this episode for me is how informal Layla’s learning experience was and yet she managed to become a successful developer.

As I continue in my own personal journey in software development, I’ve learned that though a formal education is invaluable, life experiences and projects that require me to develop/code are also critical.

Lastly, in this podcast episode, Layla referenced a couple of things that pertained to our course topics. She mentions how using a .Net framework was crucial for her creating her business website, she discusses how her friends taught her the principles of object oriented programming, and discusses how she focused on the front end of her website to make sure it was user friendly, while her partner worked on the backend to make sure her customers’ information was properly stored and managed.

This week, we reviewed about the concepts and the differences between the five terms, which were abstraction, interface, inheritance, encapsulation, and polymorphism. However, the term polymorphism confused me a lot during the class. The only thing that I remembered about polymorphism was that a class or an object could exist in many forms, but I could not explain to myself what “forms” mean. So, I did some searching on the term polymorphism in the hope that I could recall what I had learned and also learn more about the characteristics of polymorphism.

Fortunately, I found a good resource, called Polymorphism, Encapsulation, Data Abstraction, and Inheritance in Object Oriented Programming, written by Nick. Through this blog, Nick provides readers with concise definitions of abstraction, encapsulation, inheritance, and polymorphism with typical properties respect to each term. The writer also analyzes the important role of each concept in programming. Furthermore, after defining each term, Nick also has at least one example to describe the definition making the terms easier to understand for code newbies. This is one of the reasons that I chose this blog as my resource. In particular, in the polymorphism section, Nick gives an example of the class “Move” and the classes of animals to explain the phrase “exists in many forms”. The class “Move” does not have a concrete type, so it can be inherited/extended by any type of animal. For example, a Snail will crawl to move, a fish will swim to move, or a Kangaroo will leap to move. Hence, the concept of polymorphism is applied to make the code more flexible and extensible. This is a good blog to read and very useful if you want to understand clearly about the concepts of polymorphism, encapsulation, abstraction, and inheritance. I might forget these concepts if I don’t use them for a while. However, this blog gives me a key to remember those concepts in the long run by keeping in mind the real life examples provided by the blog.

Another thing is that after reading the blog, I know that there are several different types of polymorphism, but the writer does not analyze those types in depth in the blog. Therefore, I searched other sources to learn more about polymorphism. Different resources give me different numbers of polymorphism types. However, there is an article, called Polymorphism in Java, that gives me the necessary information about the types of polymorphism. There are many types of polymorphism, but in Java language, there are only two, which are compile-time polymorphism (overloading) and runtime polymorphism (overriding). Throughout the article, each type is described and analyzed using code examples. For myself, this is a good resource because although the article is short but concise, it contains all the information I need to know. Moreover, before reading the article, I had a chance to learn about the concepts of overloading and overriding, but I did not know how those two methods relate to the concept of polymorphism. So, the article not only helped me review my old knowledge, but also helped me to come up with the idea that I would organize all the concepts that I have learned into a diagram, where the diagram will show how concepts relate to each other. I believe the diagram will be one of my best tools that I can use to remember and distinguish all the important concepts in programming.

This week, we have started talking about UML (or Unified Modeling Language) in class, and while I can see some of the usefulness of UML, I wanted to see how people actually use it in the context of a workplace environment. So as a part of this, I found a blog post by Lucidchart talking about different types of UML diagrams. While this blog post is made by a company, and they are trying to get the reader to use their product, I don’t think detracts from the usefulness of the post.

So in this blog post they talk about how Agile developers can incorporate UML into their development process, as well as 7 different types of UML diagrams and how each one is useful, and which context it is useful for. It is largely just an overview of these different models, and I know there are more types of UML diagrams, but this gives a fairly good breakdown of what UML is and how it can be used in a more real-world context. I chose this post as I personally found it useful in understanding why anyone would actually want to use UML outside of a planning stage, since you are essentially planning out the whole class structure before you design it, so in my mind why wouldn’t you just write the code? Well this post makes the case that UML makes very good documentation for your code. If you have a class diagram, like the kind we worked with in class, you can use that as a sort of blueprint for your code. So you don’t have to scroll through hundreds of lines of code just to find all of the methods that are in it and how they interact with other classes, you can just look at the UML diagram. They also make the case that UML can be a valuable tool in explaining code to others.

From this blog post, I think I have a better understanding of how UML is (and should be) used in a workplace. There are a lot of different types of diagrams that were shown that I didn’t know were part of the point of UML, as I have only ever seen the class diagrams. But there are many models that fit under the purview of UML, each with different use cases. Some model runtime behavior in a way that it could be easily explained to someone who has no knowledge of programming, and some are able to show how different methods or classes communicate with one another, creating a diagram that can be easily looked at to make sure you aren’t going to mess with interactions in a system by making certain changes. I think that, given the proper context, UML could make a much more significant impact in understanding how we code, and has the ability to explain code to others in a way that even more traditional documentation methods lack.

My name is Hung P Nguyen, I’m a senior at Worcester State University and majoring in Computer Science with both concentrations in Software Development and Big Data. The focus of this blog would be on the knowledge that I would gain while attending CS-343. Other than that, this blog would also be about me learning new techniques outside of the classroom and being able to adapt to technology. Personally, the most interesting thing that brings out my curiosity is Docker. As a necessity to many developers, Docker is playing such an essential role in their work-life which question me about its existence and practice
