Derin's CS Journey

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem Here is the Link to the repositories that contains everything we worked on Sprint-3. Backend, Frontend, Event system, and Keycloak. Connect RabbitMQ receive file to DB : Connected the MongoDB database on the received file. Implement Event System components: Implemented RabbitMq components for Event System. Meet with other Event System Teams. : Met with other teams to finalize everything about messages. New TheasPantryReport: The new Theas Pantry Report Create two channels for both teams: Created two channels for both teams on the send and receive files.   For this Sprint, I worked mainly with Austin on the backend components such as implanting the rabbbitMQ, making API, and trying to get out system working. What worked well / did not work well For this sprint, what worked best was that we got our reporting system functioning. We have a system where the Rabbitmq receives the messa...

For the last and final blog post in my capstone class, I focused on the apprenticeship pattern of “Retreat into Competence” from chapter two of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The section talked about perhaps how you are overwhelmed or beginning to realize how little you know, or perhaps you have taken on a new challenge and things are not working out so well. However, getting back into something you are good at is a nice way of regaining your composure. I completely agree with this statement, sometimes all we need a just a pullback to launch forward towards the goal. The quote provided at the beginning of the section is what stood out to me the most. It states that “You look at where you’re going and where you are and it never makes sense, but then you look back at where you’ve been, and a pattern seems to emerge. And if you project forward from that pattern, then sometimes you can come up with something.” This got me thinking very d...

For this week’s blog post, I read the section “Learn How You Fail” from chapter five of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The quote beginning of the section is what stood out to me the most. It says, “Ingenuity is often misunderstood. It is not a matter of superior intelligence but of character. It demands more than anything a willingness to recognize failure, to not paper over the cracks, and to change.” The section talked about how sooner or later you may face failures but the right thing to do is push forward at the boundaries and learn to overlook the mistakes you have faced. In our field, we face many failures but that is not holding us back to accomplish the goals we have set for ourselves. The author mainly talked about becoming conscious of the things that trip you but allow yourself the choice of working to fix the problems that are cutting the losses. One of the most important things to do when you face failure is to accept ...

For the last and final blog for the CS 433 class, I want to focus on an interesting topic that is automation testing. Nowadays, most companies have implemented automated testing environments. It is the best way to increase effectiveness, test coverage, and the execution speed of software testing. Before I get started, what exactly is automation testing? Well, automation testing or Test automation is a software testing technique that performs using various software tools to execute a test case suite. The automation testing software can enter test data into the system and compare expected and actual results with the generated details test reports. There several benefits of using test automation, it is the best way to increase effectiveness and save money. Other factors include manual testing, which is time-consuming, Test automation does not require human intervention and can run automated tests unattended or even overnight, it is reliable in results, improve accuracy, better speed, and ...

During class, we have been doing many testing methods including Junit 5 and for the past two weeks we have been using Mockito, so for today’s blog, I want to focus more on the framework and testing with Mockito. Before we get started let us talk about what is mocking. Mocking is a process of developing the objects that act as the mock or clone of the real objects. In another word, mocking is a technique where mock objects are used instead of real objects. The purpose is to isolate and focus on the code being tested. Mock uses objects such as Fakes, Stubs, and mocks. A fake object has working implementation but takes shortcuts which makes them not suitable for production. Stub object usually does not respond to anything outside that is programmed in for the test. Mocks are objects that are preprogrammed with expectations which form a specification of the call that is called to receive. Now let us move on to what Mockito is, Mockito is a java based mocking framework ...

For this week’s blog post, I read the section  “Expand your bandwidth” from chapter five of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The main reason this pattern was Interesting was because of a quote that stood to me. It was “[L]earning about what we don’t know is often more important than doing things we already know how to do.” This quote is so accurate. Especially in a technology-driven world, it is always evolving. so, developers must learn new technologies and software’s all the time. It is important to prioritize learning what you do not know. Later in the section author mentioned the overwhelming aspect of learning new information and expanding your ability, it is important to expand your knowledge and experiences in multiple dimensions such as: reading a book, social media, blogs Groups, and other academic resources. The second half of the pattern talked about how Once you understand how to Expand Your Bandwidth, the next ...

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem Here is the Link to the repositories that contains everything we worked on Sprint-2. Backend, Frontend, Event system, and Keycloak. RabbitMQ Docker container:   Created a Docker container for Reporting Team Learn how to get messages from Queue:   Learned How to send and receive messages using JSON object Meeting with other Event System Team:   Met with the other teams to discuss the format and schema Review CSS and HTML:   Reviewed CSS and HTML for the Frontend design. Work with Backend/Database for MQ : Worked with Database and Backend to figure out the Receive file. For the Sprint, I worked mostly on the Event System components with the Backend person. We figured out how to properly send and receive messages using the JSON object. What worked well / did not work well For the Sprint, I worked mostly on the Event System components with the Backend person. We figure...

For this week’s blog post, I read the section  “Record What You Learn” from chapter five of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The section started with a quote by Atul Gawnde in which it states: “You should not also underestimate the power of writing itself....You can lose your larger sense of purpose. But writing lets you step back and think through a problem” This reminds me a lot of myself because I am usually the one that never writes anything down, Instead I will believe that I can remember it. However, later I forget it. As I get older, I realize that recording something is useful, for example, if we are doing a project sometimes it is a good idea to draw diagrams and analyze through writing which helps to organize and plan it out. The section mainly talked about the practice of keeping a diary or a journal that will be useful throughout your career. The author also mentioned avoiding falling into the trap of just writing...

For this week’s blog post, I read the section  “A Different Road ” from chapter three of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The section talked about how taking a different road could be a risky or life-changing event.  Despite this risk, I believe that one should be not afraid to do something different with your life. A change no matter whether they seem good or bad at the time will teach you something new or a new experience that can drive you to push forward. The author started the section by talking about explaining how saying goodbye to the craft can be risky, but  “Even if you leave the road permanently, the values and principles you have developed along the way will always be with you” I think this is very true, no matter the change, the principles you have acquired so far in the career will always be there for you. Currently, I want to talk about the sad reality and risk one may face when one changes a craft. The ...

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem/new-sample-project This is our example repository that contains everything we worked on for Sprint 1. Review Docker: Reviewed old projects and main commands for docker. Create Sample Docker projects: Created a sample Docker Project, Did the getting started activities. Repository for event project: The main repository for the event project. Learn About RabbitMQ : Learned RabbitMQ components and Implemented them using Docker. Review Scrum :   Reviewed the scrum guide and understand the process. For the project, I am part of the reporting team. I mainly work on the event system software that sends and receives a message to other systems using the RabbitMQ messaging system interface. I also work with the database person and did make a docker example project and a cheat sheet of all the docker commands. What worked well / did not work well   The thing that worked well for our gro...

When it comes to a large pool of input data, it is not possible to perform exhausting testing for each set of test data. There should be an easy way to select test cases from the pool so that all scenarios are covered. This is when the Equivalence Partitioning & Boundary Value Analysis testing techniques were introduced. In today’s blog, I want to do further research on the testing technique of Boundary Value Analysis and Equivalence Partitioning Testing. Equivalence Partitioning and Boundary value analysis are linked to each other and can be used together at all levels of software testing. To start, Boundary value testing is the process of testing between extreme boundaries between the partitions, for example like start, end, lower, upper, maximum, minimum, just inside, and outside values. Normally Boundary value analysis is part of stress and negative testing. Using the Boundary Value Analysis technique tester creates test cases for the required input field. Now when it comes t...

For this week’s blog post, I read the section  “Nurture Your Passion ” from chapter two of the book Apprenticeship Patterns by Dave Hoover and Adewale Oshineye. The section talked about how the work environment can stifle the passion for the craft. For example, you might be a software developer with a passion for the craft, but unfortunately the daily activities, “demoralizing corporate hierarchies, project death marches, abusive managers, or cynical colleagues.” Can become hard for your passion to grow by staying in such hostile conditions. I think this is true for the majority of the people that work in the IT field. I have seen especially my family members whose having such a hostile situation at work especially when there is a deadline that is approaching, or a software release is going on. The author goes further into project death marches in which he explained how they are the most damaging of the hostile situations, it takes your time and energy, preventing ...

In class, we have been learning about the different types of testing methods. Today I want to focus on Black-Box vs. White-Box testing. Let us start by looking at how each test method differs from the other. Black Box testing is a software method in which the internal structure design and implementation of the item being tested are not known to the tester. However, in white box testing, the internal structure, design, and implementation are known to the tester. Let us start by looking at a diagram example that was provided in one of my resources for black-box testing. The picture above of Black Box testing can be any software system. For example, a website like a google or an amazon database. All under the Black Box testing, you can test the applications by just focusing on the inputs and outputs without knowing their internal code implementation. There are many types of black box testing methods, but the main types are functional, nonfunctional and regression testing.   Now let ...

For this week’s blog post, I read the section   “Unleash Your Enthusiasm” from chapter two of the book Apprenticeship Patterns  by Dave Hoover and Adewale Oshineye. The section talked about how software developers especially the newcomers find themselves self-holding back the enthusiasm you have towards the work than your colleagues. Mainly due to the fear of making a poor impression on your coworkers. As I was reading the pattern, I feel like it has a personal connection to me because I see myself in the same situation of holding back on certain circumstances, Mainly I do not want to make a bad impression. The author states that ” Most teams are not hyper passionate or overly enthusiastic about technology. Predictably, they are focused on delivering the next project or improving on the aspects of the development life cycle that are causing them pain”   I completely agree with this statement, I see many people nowadays in the field of technology are not passionate about t...

For this week’s blog post, one pattern that stood out to me the most was “Your First Language” I believe that the first language will be the most important one for our careers because for the next few years this will be the main language, we use to solve problems or practice to improve.  My first language technically was HTML that I learned back in a web design class at High School, but my first official language is Java from our CS 140 class. From that class and onward I have been using java for almost everything even for personal projects or in other classes. As I was reading the rest of the article, I came across a sentence how the author states, “For several years, your first language will be the framework against which you learn other languages. The better you know your first language, the easier it will be to learn your next language.” I believe this is very true, your first language will be the foundation for the rest of the languages you will be learning. I remember when ...

In class, we have been learning about testing with Junit 5 and doing assignments related to it. After watching the video for the advanced part of the assignment,  I decided that I wanted to research further into the topic for my first blog post. So, what is Junit? In a short answer, JUnit is a Java open sources unit testing framework that is used to write and run repeatable automated tests. JUnit 5 Is the updated version of the highly popular testing library that is Junit 4 which I’m sure you all have heard of it. Junit 5 was released in 2017 that adds good use for Java 8 features. In fact, JUnit 5 requires Java 8 JDK or higher to work. While researching a few of the key differences between the two versions are Junit 5 is composed of 3 sub-projects JUnit Platform, JUnit Jupiter, and JUnit Vintage. The Assertions and Annotations have been changed, and most importantly Junit 5 adds the support of the lambda expression in which we went over in class. One of the blogs I read recommen...

We are at the point of life that in a few years we all be fully working adults. It is crazy to think that 4 years of college just flew by so fast. This semester the software capstone class will be the most interesting and challenging I believe. When it comes to reading a book, I have no patience at all, but after reading the introduction, something about this book: Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman is making me want to read it appropriately. It is possible to be that I can relate to this book on so many levels and it is relevant to me. After just reading the introduction I feel like it changed the way I think and view my profession. All the patterns in the book are interesting and powerful in a way that we can adapt and combine these patterns in many ways and situations. One of the patterns that stood out to me the most was “Be the worst” from chapter four. The author has explained the concept very well in which it states that “Surround yo...

Hello Everyone, I'm Derin Sabu, this is my introductory blog post for CS-443 and CS-448. Excited and looking forward to learning new concepts. It won’t be easy, but it is worth it.  Good Luck!

This week on my CS Journey, I want to focus on Agile software development and its methodologies. Agile methodology is a type of project management process, mainly used for software development. It evolves through the collaborative effort and cross-functional teams and their customers. Scrum and Kanban are two of the most widely used Agile methodologies. Today I want to focus mainly on Scrum. Recently I saw that employers are looking for candidates who have experience in scrum and agile development, so it is important that we learn more about it.   Scrum is a framework that allows for more effective collaborations among teams working on various complex projects. It is a management system that relies on step by step development. Each cycle is consisting of two-to four-week sprints, where each sprint's goal is to build the most important features first and come out with a potentially deliverable product. Agile Scrum methodology has several benefits,  it encourages pro...

This week on my CS Journey I want to focus on REST API Design. In my last blog, I talked about how an API request works and how to be able to read the API documentation and use it effectively. In this blog, I will be emphasizing briefly the key constraints to REST API design. There are six important constraints to the design. Which are: Client-Server, Stateless, Cache, Uniform Interface, Layered System, and Code on Demand. Together, these make up the theory of REST. Starting with client-server constraint is the concept that the client and the server should be separate from each other and allowed to evolve individually and independently. In other words, a developer should be able to make changes to an application whether on the data structure or the database design side at the same time it is not impacting the client server side. Next REST APIs are stateless, meaning that calls can be made independently, and each call contains all the data necessary to complete itself successfully. ...
