Your First Language

For this week’s blog post, I have decided to look at the apprenticeship pattern “Your Fist Language”. The idea of this pattern is when you first start your programming journey. This is when you only know one or tow languages. The main concept of this chapter is to isolate what langue you would like to use as your main language. According to Dave H. Hoover and Adewale Oshineye, the authors of the book, they say on this, “Pick a language. Become fluent in it. For the next few years this will be the main language you use to solve problems, as well as the default skill you hone whenever you are practicing. Making this choice is a challenge. It is important that you carefully weigh the options, as this is the foundation upon which your early career will be built.” (Dave H. Hoover & Adewale Oshineye).

When first reading about this pattern, it really grabbed my attention. At Worcester State we learn an abundance of different languages to be able to be prepared for the outside world. However, something that has always been a question for me is “What language do I stick with?”. What was cool about this chapter was that it said to have a main language under your belt, but it never said to toss aside the other languages. As an example, they talked about a job requiring a specific language to be able to be hired there. Rather than disregarding the job and looking for something else, they suggest making a toy application to learn a basic understanding of that language. Some of these toy programs will involve a problem to solve. Unlike a simple “Hello World” application, solving a problem will give you a more in-depth dive of the language. Another good thing to add to your toy application is a test class. Test classes always help ensure that what you are coding is spitting out the correct information.

With this chapter in the book, I agree with everything that they are saying about your first language. I loved how they talked about having a min langue but not disregarding the other languages you have learned or will learn.  It also made me consider more what will be my main langue when I go out into the field and what language I’m willing to put more research into.

The Deep End

Months ago, I found myself standing in “The Deep End” since I wasn’t able to land any internship before graduating this year. The situation was exactly the same as how they described in the book, I needed to grow more skills, my confidence, and my portfolio of successful work, I needed to challenge myself with bigger works, projects, complex tasks, and teams, etc. The YouTube algorithm even made my situation worse by showing people about my age are “better” coders than me in my opinion. I was afraid that I did not do “enough”.

 Currently, what I really felt at that time was envious, seeing people better than me virtually is rough but seeing people who I know landed works while I carried them through classes is overwhelming. My resume, my ability, my confidence, all of them were kind of irrelevant at that point. I created an invisible time limit for myself to be successful, to this point, I still think there are pros and cons to doing it, the risk could be high but I take it.

Later, exactly in how they advise the action, I should instead jump into working on projects that I did not do to create a time limit for it, I’m willing to take more work than anyone in the team and fulfill my responsibilities to not only build my portfolio but also my skills and my confidence. Then, after a while, I will analyze my set of skills fit to what role in the industry and pick the right opportunity based on it.

Besides, when this post is online, I’m currently handling an internship and a capstone project in which I volunteered to be the Scrum master that instead does not make me feel overwhelmed but motivated, as I am learning new materials every day.

In conclusion, it likes how The Deep End was described in vol. 15 of “Diary of the Wimpy Kid: The Deep End”, which follows Greg Heffley’s summer story, a dramatic summer yielded great memories, things could be tough initially, but if I keep continuing on this track, hopefully, the result will be what I aimed.

Sweeping The Floor Learning Pattern

This pattern is very important it tells us how to begin the career switch from student to paid professional. It is a scary moment of unprecedented uncertainty. It helps us see with a clearer image that there are levels of expectation. These expectations are stratified to build a path to success. It also throws cautionary tales of getting comfortable doing the work at the outer layers of what’s expected.

This is very personal because everyone of us graduating will face the reality of a professional environment. I could not say that it will be harsh or easy. What I can say is that the expectations and anxiety that we generate ourselves is harsh. It makes me feel better to think that the professional world in general has a path in which one can climb, even if this path is steep. The great fear is that there is no path, the goal is the space station, and you don’t know how to build a rocket.

Putting my trust on the writers I expect this sweeping the floor pattern a practiced reality in real situations. I don’t believe there are any menial tasks. All tasks must be completed, and I wouldn’t mind if I had to do some of them or even all of them if it’s all I can do. I have used this pattern in my own life differently. When my car brakes I usually fix it myself because I can not afford the extra expense, this is something that I really don’t want to do. It takes time away from my studies, but it also helps me afford it. Some people say why should they pay a mechanic x amount for only an hour of work but the amount it would take a normal person without the tools and environment would much offset whatever savings they think they had. Most of the time I think if I had the money, I would pay double for a professional to do this for me.

You learn the cost of doing something by doing things you wouldn’t necessarily want to do. Sweeping the floor may begin with doing the easy undesirable work but it must progress into doing work you are uncomfortable with. Success in life comes when you accept uncertainty and never get too cozy as to be paralyzed by extraneous events.

Find Mentors

Self-learning is one important quality of any programmer; however, self-learning is not always useful since the learner might not know what is waiting for them and if their approach is good or not. In this case, every learner needs mentors, those who already achieved what we are working on or at least, they have deeper knowledge about the topic that we are learning.

“Whether a beginner starts out with a training course or is self-taught, the first step on the path to software craftsmanship is finding a craftsman to apprentice himself to”

–Pete McBreen, Software Craftsmanship, p.96

From my own experience, I find this statement can’t be more accurate as I find myself learning more productive when I have mentors to show me what I should do compared to learning by myself. However, as in the book illustrated, as an apprentice, it can be difficult to tell who is truly a master craftsman. Therefore, an apprentice should follow a set of mentors that each one will show them a bit of a huge picture. And the set of mentors here counts not only “real” people who we should have already considered them as our mentors to learn, our friends and our professor, but also the active community we could find online to exchange information with people on it.

Besides, according to what was written in the book, an apprentice shouldn’t expect their mentors to know everything and get disappointed if mentors don’t know what we are seeking for as the current mentors could be other’s apprentice, we are all walking on a long road. Because our field is huge, a person who can guide us through 10 in-built React hooks may not be able to show you how to design the API route and vice versa, these twos are completely different topics and what we probably need is to master a specific set of skills that we desired; but it’s obviously the more we know, the higher opportunities we’ll have.

In conclusion, what I learned from this chapter is that I should find a community and actively communicate with other members there. Luckily, I found myself on a discord channel of one of the biggest Vietnamese tech forums, J2Team, having a community of developers exchanging lots of quality contents.

Now, I should consider posting my first message here and seeing where it will lead me to.

Unleash Your Enthusiasm Pattern

This week I decided to read about the apprenticeship pattern ‘Unleash Your Enthusiasm’. The meaning behind unleashing your enthusiasm is that there may be something that is holding you back. Just like the pattern says, you have so much enthusiasm that’s ready to be release. The example that the book uses, is that software developers, you will more than likely be working as part of a team. Usually when working in groups, there is something called a norm which is what everyone follows. No one tries to stand out or if they did, they would find themselves in an uncomfortable position.

My initial reaction to this pattern is that it can relate to more than just software development. It can be compared to the outside world. For example, who you choose to have as your friends. In my instance, I used to have a circle of friends I used to ‘confine my enthusiasm’. Eventually I learned that they were holding me back from furthering my life from being greater. Once I started being myself, things naturally got better for me. My life got overall got better ever since I hold myself back. Just like how some new software engineers that start their first professional jobs confine with the norms. They become held back because they don’t want to speak up and voice their own opinions which then results in them becoming an ordinary worker who doesn’t stand out.

After reading the pattern, it has definitely made an impact to how I view myself working in a professional environment. I tend to be a quiet person when working in teams but lately have been more active and more vocal in the teams I am in at school. By doing this, I believe it will help me get out of my comfort zone and allow myself to ‘unleash my enthusiasm’.

This pattern can be applied to not only for software developers, but to their personal lives as well. I would agree with what have been said in this pattern because the meaning behind it, is to just let loose your ambitions. In order to grow and further your career, you can’t become a person who holds themselves back. There are times when staying in the norm is okay, but overall, it’s better to stand out because that is how you will get recognized.

Digg Deeper Learning Pattern

This pattern is a great idea for a beginner such as me. It offers a way to complement the lack of knowledge that comes with the lack of experience. It should be used carefully because of the ease of wanting to just reinforce the skills you are already good at. Knowing a little on a lot of subjects will not help getting things done and knowing a lot in just one subject will get you just as far. The secret as I see it is to have a good toolbox and know how to at least hold each tool. As you need to pick up each of these tools you learn about them more in depth but not too much to hinder your progress. As you shuffle through this toolbox picking up things you need and not obsessing on one tool you build a hierarchy of depth in the knowledge of things you need most. We will handle the same tool more than once and every time we do, we should dig just a little more.

The author presents a more all in version of the dig deeper which I think is the philosophical normalized world idea. It would be nice if we had the luxury of tunnel vision and look for the PhD dissertation of the original design algorithm for every tool we use, but it is also the easiest way to fall into a deadlock. I find that in school it is very hard to get in depth knowledge on every subject as much as I want. Time and time again I see myself compromising and kicking the can down the road, because I do want in-depth knowledge in some subjects, but there are time sensitive co-responsibilities that need immediate attention. Although, as I said earlier, some of these tools that I want to understand better come up again and again over the semesters and I do indeed gain a little more ground on understanding them.

I believe the author is right when he says that we need to learn to dive into ever lower levels of understanding.  By lower I mean from specific to general and by specific, I mean not only the surface high level function you need. The author does throw a little caution which I also mentioned earlier. The risk of becoming what some call a one trick pony.  The balance is really hard to define, and it is very personal. I don’t have my own balance definition yet, but I hope that with time this too will come.

The White Belt

As I started looking into the list of patterns, “The White Belt” hit the nail on my head as the problem illustrated in this pattern looks like what I’m currently facing, or have been facing against for a while I would say. I think the first time I found myself in a “wrong place” with programming was in a Hackathon back in spring 2021.

The situation was my teammates were all having Java background so we decided to create an Android Application using Android Studio so everyone can write code in Java. However, things began to feel strange as we started, Java here is not what we were familiar with actually, the coding concept is different as we have to understand what we need and find out the right documentation according to the problem, something that we were not supposed to do initially, but it’s impossible to change the project now as it might collapse team spirit. Therefore, I had to wear the “black belt” and learned the hard way to figure out how to implement features in a short period of time. The repository that we were working on that time if you want to check: OPCredit

This project damaged my thinking more than it improved my knowledge as I feared that my personal development has stalled because I can’t write Java while Java is my first programming language. According to the solution and action indicated in the book, I ameliorated the situation by learning basic JavaScript, I was impressed by how less complex the code is compared to Java while doing the same thing. Then, as I proceed to learn its frameworks, and from ES5 to ES6, in my view, this is one perfect instance where you shouldn’t suppose to already know what will be implemented, but to be neonate and accept the concept.

By the time this post is online, I was learning CI/CD and Docker, something that is not related to my first language as I will have to understand what is happening in the Command Line Interface to give the container the correct solution. This time, I will wear “The White Belt” even more carefully to not only learn what I have to learn but also to practice how to use this belt for future progression.

White Belt Pattern

For my first Apprenticeship pattern, I chose to write about “The White Belt”. In this pattern, you’ve created a good understanding of the first language you’ve learned, and others have recognized and have often called you for help when they have problems. Even though this is great, you feel that you’re have a little difficulty trying to learn new materials and find that things are slowing down and you’re not learning as quick as before and fear you have hit a peak of your personal development.

When I first read about this pattern, I did in fact felt like I hit a plateau in obtaining new skills and in self learning. I could relate to the description of the white belt very much. I really loved how they quoted Yoda from Star Wars with “You must unlearn what you have learned”, regarding approaching new situations. Another quote that I liked while reading about this pattern is “In order to climb, you must leave the sure footing, letting go of what you already do well and possibly slipping downward into a ravine. If you never let go of what you already do well, you may continue to make steady progress, but you’ll never get off the plateau” by Jerry Weinberg. Both quotes are quite similar and suggest that in order to learn and make a steady progress, you must leave your comfort zone and tackle the problem with a different method. This helped me come to the realization that I’m constantly trying to incorporate another programming language that I was comfortable with the new language I’m trying to learn. Which results in me having a hard time learning new things for both languages. After I took a step back to analyze what was going on, I went back and tackle each language in a separate way. I then was able to learn and get past the plateau I was on.

There isn’t anything I would disagree with what was said for this pattern. Everything that was said was great and would really help others who have also hit a plateau. The story of Dave was a quick and simple way of relating the quotes I said earlier and applying them. Overall reading about this pattern has helped me come to the realization that there are some problems that should be handled differently, for instance when learning a new problem or a technique of how to do something.

Reaction to Apprenticeship Patterns

My initial reaction after reading Apprenticeship Patterns by David H. Hoover and Adewale Oshineye, was very eye opening for me. It made me rethink about my future and goals and what I want to be able to achieve. The story of Dave which displayed his experience was very helpful. Apprenticeship Pattern is a book I would definitely recommend to people who are getting into software development. It’s a book that gets your mind ready to go on a journey from an apprenticeship to journeyman status. While reading the introductions from Chapter 2 thru 6, it really inspired and motivated me to do my own learning other than what I am currently doing in my university. I would agree with the reading however, I do believe some people may disagree depending on their mindset and goals. In the book it takes about how some people become the “better than average developer”. This isn’t what I want to achieve, instead I would like to someday develop an application that is useful or that can help communities and to be able to do that, I need a mindset of a master. A master is a step above a journey man who completed their apprenticeship. The mindset of a master is to constantly get better at their craft and they’re always learning new things.  The chapter that I believe that is most relevant to me right now would be in chapter three. In the intro of chapter three, we follow Dave who decides to branch out and connect with other developers through a website. After this he met a few hackers that inspired him because were experts in their craft but were still learning new things at a fast rate. This made him realized he just barely scratched the surface of being a great software developer. After a few interactions and observations, he captured the learning process and threw himself into anything he can get his hands on. This last part is what I can really relate to right now. I am trying to learn as much as I can before the end of my semester and to work on a few projects that will help be harness my skills together.

Apprenticeship Patterns Relfection

The author aligns software development with a craft rather than strictly a science. A craft is an art or skill where tools, methods, and knowledge are required to be an expert. He gives various examples that show how craftsmanship is needed to create well-designed software, and I agree with this point of view. I believe software development should be approached as more of a craft, especially when it comes to how programming is learned through apprenticeship.

Rather than traditional school-based education, programmers would learn from experienced people. Not from books and assignments where one’s ability is determined from the accumulation of grades.

There should not be the target for an education system that creates a class of ‘programmers’ who know general knowledge about computer science and the basics of programming, but an environment that helps each student master their software development craft. We shouldn’t focus only on code but should focus on improving how we approach programming.

An area where I see this approach put to practice is in coding boot camps. These are usually fast-paced programming courses that last less than one year. The classes are taught by individuals who have deep knowledge of the field and years of experience as professional programmers. Instructors have worked in corporations directly with the tools and technologies they teach their students. It is also an environment where learning programming is more hands-on. Creating projects is the center point of a coding bootcamp. The curriculum is much more comprehensive on practical knowledge than what is taught in the traditional college environment; relating to what students will be working on in a future job. I find less use in the existing 4-year college degree model of education. I am not the only one, as the rates of college enrollment are dropping year after year. Ultimately, a college degree acts as a form of accreditation, but the value of a degree is losing value with time.

To me, the most relevant chapter was 4, “Accurate Self-Assessment.” It is common to learn just enough to accomplish what is needed to be done and not extend your knowledge any further. Learning something new takes effort, and it is much easier to remain complacent with the technologies we already understand. The author also suggests comparing yourself to whom you were yesterday and avoiding comparisons to someone else. The benefit of this methodology is you identify your growth over time. And once you realize the distance between who you were yesterday and who you are today, changes can be made to reach levels of improvement of where you want to be.
