Programming is a skill that requires applying the right patterns to various scenarios. To become proficient in pattern applications, it’s helpful to analyze how other developers have used them. One great approach is to study open-source code published by experienced programmers. Carefully reviewing their work can spark ideas on how to enhance one’s own programming patterns and projects. This enables developers to expand their skill set and gain inspiration from the expertise of others.

I find it intriguing that as I read more code, I find it easier to comprehend. It’s fascinating to think that this improved comprehension reflects my mastery of the craft. Additionally, I discovered an interesting suggestion to track code changes over time using git. By reviewing the history of a codebase, I can gain insights into how the code has evolved and identify patterns that proved successful in the past. This knowledge can then be applied to the code I write in the future. Being able to observe and understand the evolution of code not only helps me identify errors that were initially overlooked but also provides me with an opportunity to continuously improve my programming skills. By incorporating successful patterns into my own work, I can strive to produce high-quality, efficient code.

When I use open-source packages, I sometimes face challenges where the documentation doesn’t fully explain how to use the package. It can be frustrating, but I’ve learned that diving deeper into the source code provides an excellent opportunity to learn from the author’s coding patterns and techniques.

I completely agree with the insights provided by the pattern, which suggests that going through open-source code or someone else’s code is an excellent way to learn from experts. I believe that studying experts’ codes is the best way which can help me with much more than just how to use a particular software package. By observing the patterns and techniques used by skilled programmers, I can improve my own way of programming and learn to write more and make code run efficiently. Inspecting open-source code is a crucial aspect of my development process, and I plan to continue doing so in the future. It’s a great opportunity to learn from the best and enhance my programming skills.

This weeks blog read of choice was a blog called “ Polymorphism in Programming” by Jonathan Johnson. This blog goes throught what is polymorphism, how to use them and also the different types that there are. One thing I thought was funny is that it compares ciderella after midnight m and before as polymorphism. Since polymorphism is when the object undergoes transformation. In programming the oject tranforms in compile time and dynamic and what does the transfmation is the method and object. Polymorphism is very essential to object oriented programming. Four different types of polymorphism are subtypes polymorphisms, parametric polymorphisms, and hoc polymorphisms and coercion polymorphisms. Subtype polymorphisms is the most common kind, it uses of class name to refrenece multiple kinds of subtypes at once. Parametric polymorphism which is also describe as overloading specially provides a way to use one of its functions to interact with multiple types. Ad hoc polymorphism also known as compile time the function with the same name acts differently for different types and lastly there is coescion polymorphism is the direct tranfomation of one type to another this happens when one type gets cast into another type. The reason why I picked this blog post was because we went over polymorphism in class a while back but I personally did not take the time to dig deeper into the subject so this was a good opportunity to dive a little deeper. Which is what I was able to achieve with this blog post. It refreshed what I learned about the different types of polymorphism and really helped me grasp the concept into a more deeper level. The reason why I picked this blog post is because I like the way it was formatted and how it is organized with its information. I also like the graphics that they used to explain it. It brought a simple and a more clear picture. Especially when they used Disney to connect to reader. I really appreciated that, it brought a sense of light weight to the read. There was a lot of information but it was easy to intake because of the organization. I hope to take a lot from this blog post, and use polymorphism to reuse code more effectively, to also use same variable for multiple date types. And also to reduce coupling with differently functionality types. Hopefully these clarification with different types help me excel in this so that when I do need to reuse code I can do it in the best format possible using all the architecture structures that I am learning.

This article from InfoWars main goal is to explain the Law of Demeter, which is something that I have never heard about before this class. The basic premise of the Law Of Demeter is to ensure that classes and objects should never know the internal design and content of other classes. This promotes loose coupling and allowing code to be easily modified and changed in the future. First discussed in 1987 at Northeastern University, the law was developed to help software designers create code that can be understood and modified easily. This seems to be the main goal for most design laws. With more coupling, there is more confusion. The Law of Demeter will ensure that there is minimal complexity within code from restricting classes to have excess knowledge of the inner workings of other classes.

The main reason I selected this article for this weeks blog post was because it again showed some visual examples of code being used in the Law of Demeter, instead of just plain text. As I stated in another blog post, I enjoy seeing pieces of code that show the principle being used, and showing its violations. This article was also another free resource for many beginner coders to utilize to enhance and optimize their code. This is a concept I did not know about before taking this class. Reading the article, I connected the main points of the Law of Demeter to concepts we have learned in class, such as loose coupling. I’ve never realized that those small concepts we learned in class had much bigger implications in the world of software design, such as having a whole law dedicated to it.

In the future, knowing the Law of Demeter exists will help me make sure my code utilizes loose coupling, so that my code can be easily understood and ready by my co-workers on the project. Having code that is easy to read and understand is important when working in a team environment, as you can write something that you personally understand easily, but if a co-workers takes over your work, they are left in the dark as to what they are reading. This also promotes communication in the work environment, such as having standards for writing code so that everyone is on the same page when it comes to creating code, and allows for a more fluid and effective work environment.

This week in CS-343 I’ve been getting familiar with REST APIs. This is not the only time I’ve had to use a REST API; I had to use them in my project last year for operating systems. REST APIS as explained in the stack overflow blog “Best Practices for REST API design” are one of the most common kinds of web services available today. It allows various clients including browser apps to communicate with a server via REST API. It’s important to design the REST API so that the client can properly and effectively communicate with the server.

First, what is a REST API? A REST API is an application programming interface that conforms to specified architectural constraints, like stateless communication and cacheable data. It is not a protocol or standard. REST APIs should accept JSON for request payload and response to JSON. JSON is the standard for transferring data. On another note, while transferring dates, I didn’t use JSON in my project, instead, I ended up using Curl. A curl is a command-line tool for transferring data, and it supports about 22 protocols, including HTTP.  It’s very good when testing REST services, but the blog and most sources I would say would recommend JSON for requests/responses. I was familiar with JSON files, it’s common, but now I understand why using JSON is the more optimal.

Endpoint paths are used to grab/modify whatever information you might want from the REST service. The most common ones are GET, POST, PUT, and DELETE. GET retrieves resources, POST submits new data to the server, PUT updates existing data, and DELETE removes date.  Creating routes are how we can use these endpoints. For example, let’s say that we have a route called article, POST /articles/ is for adding a new article, PUT /articles/:id is for updating the article with given id, DELETE /articles/:id is for deleting an existing article with given ID.

To avoid any confusion when an error occurs, we have HTTP response codes so that we can figure out the root of a problem, the common HTTP status codes include 400 Bad Request This means that client-side input fails validation. 401 Unauthorized – This means the user isn’t not authorized to access a resource. It usually returns when the user isn’t authenticated. 403 Forbidden – This means the user is authenticated, but it’s not allowed to access a resource.404 Not Found – This indicates that a resource is not found. 500 Internal server error – This is a generic server error. It probably shouldn’t be thrown explicitly. 502 Bad Gateway – This indicates an invalid response from an upstream server. 503 Service Unavailable – This indicates that something unexpected happened on server side (It can be anything like server overload, some parts of the system failed, etc.).

This doesn’t cover all the details of REST API but for the most part, this will get you a decent understanding of how it all works.

For this week I wanted to dive a little deeper on the APIs that we has begin to work with in the previous lab, it interested me how these systems work and wanted to see how different examples out in the world worked and how it related to how we interact with the systems themselves.

In the blog the author goes deep into how the API System are very apparent throughout the world and how they work, the best example I saw was a calendar system on google. The user would send a request to googles remote server and then the server would respond with the site to allow the user too book on the calendar, one the user set the date the request would be sent back to the server and a response would be sent back to the user. As someone who uses other systems like booksy to book haircuts with my barber its interesting how the API allows me to book it on my end while it does all of the work for me interacting with the server and changing my barbers calendar to integrate my appointment.

In the case of the work we did in the lab it is interesting to see how the API used for the pantry relates to some of the APIs discussed in the blog, when we worked we saw the all of the different actions in that API which led to either the collection as a whole or individual students when we looked to post new details or retrieve details. It is interesting to see how similarly the example we worked on works with the blogs APIs, where ours is more adding students taking food or putting food in the pantry, while also logging what is taken or what is put in, there examples is access to a Weather API to check weather in certain areas or the facebook API to give the user their profiles information.

One part that the Blog focuses on heavily is Object Oriented design, where there is a large list of objects and each object has an API which allows the objects to interact with one another, much of what is said leads back to our earlier lab seasons focusing on the different design models and which ones work better, the API aspect of it is now made relevant on how these objects interact with each-other on the users side.

In 1980, I attended a 3-month course at the Center for Computer Education in Lynnfield and was taught “Structured COBOL programming”. I then worked for the Commonwealth of Massachusetts Department of Welfare for 4 years, using COBOL as my first programming language. I had no real mentors here but did make a number of long-term friends. The lack of a mentor made it hard for me to progress as much as I did later in my career, where I had the advantage of working with some really smart people, so it is good that I learned to love computers early on at this job. I was pretty self-directed. Towards the end of my time at this job, I was able to work with some PL/I consultants who showed me what a “real” programming language was like. With this new knowledge, I was able to change jobs, and to double my salary first at MGH, and then at SEI corporation.

Around this time, I attended a course in PASCAL at UMASS Boston, and a PL/I course at Boston University. These jobs had people who were able to teach me some new tricks, but I also was able to return the favor to them. This lack of mentorship in my early years I look back on as a benefit. I was really “thrown into the deep end” in many places, which really helped me to keep learning as much as I could on my own. If I hadn’t continued to love computing, I would have certainly left my career in its early years.

I really didn’t get “Mentored” until I became a consultant, taught myself C and the Windows 3.1 SDK, and went to work at MIT. Through my consulting years, I worked at 10 to 15 companies, doing Windows UI development and SQL database work. These positions were both enterprise-level and desktop-level. There were about a half dozen people I considered mentors at these assignments, and I also sometimes acted in a mentor role to more junior employees.

I think it was fortunate that I was able to work at so many diverse organizations, because I became familiar with many new programming languages and software products, as well as obtaining a broad view of many diverse industries.

So, starting with COBOL, which I look back on and realize was a terrible language, I entered a journey which would continue to get more and more interesting as time went on. I have programmed in C, C++, C#.NET, PL/I, SQL, and a few others, but didn’t really feel I had found “The Language” for me until I started developing with Java which allowed me to convert to mobile Android development.

I am combining these two patterns because I think that one without the other will make for an improper balance of skills. This quote [1] by Carl Rogers in his book, on Becoming a Person [2] is very inspirational to me. I have made a career habit out of trying to be unique, self-directed, and perform self-directed learning.

I am also aware of the importance of being able to admit gaps in my knowledge to others. I will be the first to admit that I don’t understand something, or that someone else has a better idea than I do, especially when I think I can leverage this knowledge to improving my skills, and my personal development efforts.

Throughout my career, I have always had home-based software projects in play. The two most noticeable were Guitar Companion, (a Windows C++/MFC turned C#.NET utility program for guitarists which contained components for a notation editor, metronome, tuning fork, band manager, and video guitar lessons), and Guitar Chords, an Android app using MIDI, speech recognition, and swiping techniques to display an intuitive, pleasant looking, and efficient way to show and play any chord.

Although these efforts didn’t make huge sums of money, they did have the intended benefit of ramping up my skills in different areas, allowing me to learn from my home office, and then use this knowledge when needed at companies I worked for. The reverse effect also occurred. I was able to learn techniques at client sites, and then parlay this knowledge back to my personal efforts.

If I had not been willing to “expose my ignorance”, I would not have been able to learn many techniques from other developers. If I had been too focused on “confronting my ignorance”, I would not have done well at sharing back the knowledge I had attained on my own. This process was truly a win-win experience.

It is beneficial that as one grows in their career, they become progressively less concerned about others thinking they are not adequately qualified, because they have gained enough information to both learn and teach. This will lead to salary increases, better projects, better interviews, better companies, and ultimately to a happier career.

For this week’s pattern, I decided to read ‘The Long Road’ from Chapter 3: Walking the Long Road. The context of this pattern is that today’s society values quick success and overnight celebrities more than long term goals and success. Due to this, software developers are much different compared to veteran software developers and make the same mistakes they had made when they were inexperienced software developers. The problem of this pattern is that I, the reader, aspire to be a master software craftsman but my aspiration conflicts with what people expect from me, quick success. My guts tell me to take the highest paying job and first promotion I’m given and ignore slowly building up my skills. I thought this was pretty spot on of how society is today. Social media makes it so anyone can become an overnight celebrity which is probably one of the root causes as to why society is this way. Too much do we value quick cash and success, some people even expect it which is weird considering how hard it is to become an overnight celebrity. People need to take a step back and learn to have a long term goal and work towards your success instead of trying to get rich quick.

As for the solution of this pattern, it was basically the same as I wrote above. I should accept that I may be considered weird for thinking long term but I should accept it. I should also keep focusing on my long term goal, which is to become a software craftsman. By following the long term goal of a software craftsman, I’m able to become more skilled at learning, problem solving, and developing strong relationships with my customers. This is a good thing because, as mentioned before, people are too focused on getting rich quick and not focusing on building themselves up. By sticking to this, I won’t get rich quick like some of these people but I will be much more experienced, having built myself up long term and sticking to a goal. This is a long journey I’m not ready for but this will help me much more later in my life.

For this blog post, I have chosen the “Nurture Your Passion” pattern in which this pattern talks about how one should keep their passion for whatever they are doing secure from the inevitable draining activities that will harm your passion. When one progresses into their career, the circumstances will change and the activities you used to do for enjoyment will soon turn annoyances or be in such a crunch that there is no time for blank. It is up to yourself to mitigate these issues and to help preserve your passion.

The time of coding and working with all these programs and getting a fully functioning product is quite fulfilling to see. The work needed to get there and the problems that life will throw at your way will make you want to reconsider your decisions however such as trying to sift through countless bugs or being in a less than optimal working environment. There a number of different options to consider when trying to mitigate this issue, such as exploring different forms of media that contain information that you would like to look at or interacting with different people with the same passion to help bolster your own. The book goes into different patterns that describe these solutions such as breakable toys and kindred spirits where you have these different resources to use to help keep you going.

This pattern does indeed resonate with me as while coding has started out as a side hobby, quick and enjoyable with no commitments to it whatsoever is slowly changing to me more intensive and time consuming leading to generally less enjoyment. This makes me think of the eventual future of potential crunch times and unenjoyable meeting that will take place in which I will have to start picking up new skills to help mitigate these issues such as improving my communication skills incase any situations such as bad interactions with other people in the workplace could be solved by talking myself out of it. There is the chance of a new hot idea in the future that I could latch onto to help keep my interest up and going.
