Honing Your First Language

When I picked up Apprenticeship Patterns, on Chapter 2, Emptying the Cup, the very first pattern caught my eye when the context and problem they presented seemed to apply to my situation closely. The pattern is “Your first language”, and the authors hit the nail on the head in my case when they explain the case of a budding programmer who only has limited knowledge of one or two programming languages, but the job opportunities demand a high level of technical proficiency.

Their advice is to stick with one language and become fluent in it. The logic is to hone your language skills by solving real world problems, developing code through test driven development, with the guide of experienced programmers.

The authors stress the importance of deciding which language to take on as your first. It makes sense, seen as how that language will be the primary tool we use to solve problems. In my case, it seems clear to me which is the right one. As many of us, my first and most familiar language is Java. Not only that, I am fortunate enough to have an internship opportunity which uses Java and JavaScript. So I have the real world opportunity to hone my knowledge, and access to mentors who are more knowledgeable than myself.

One final piece of advice the authors gave which I will take them up on is to find a community of people who are focusing on the same language and have similar experiences as you. For me right now that is my peers, and it is plain to me the mutual benefits of working with others who are in the same boat.

As much as I feel internal pressure to learn a variety of languages like C++, Python, etc., reading this pattern resonated with me and helped me make an informed decision to focus on what is pragmatic, as opposed to getting caught up in the ocean of possibilities. Since my first professional opportunity is using Java and JavaScript, I will focus on honing my skills in those areas as opposed to spending that time getting a surface level understanding of a different language that I might not immediately use.

IndividualApprenticeship Patterns – Find Mentors

As we will be looking for the best skill or training from masters, we need mentors or a mentors who we can watch up to.

From the readings and with the understanding if got, finding a mentor is not all that easy, let alone mentors. As someone who want to be an apprentice or who is already an apprentice, he or she must be very careful choosing a mentor. Some of the things he or she must know before choosing a mentor(s).

  1. He or she must know her or his needs and also be very ready to be committed. Once he or she knows what he wants from the mentor then he starts searching. Only he know what things like dreams or desires and what type of person can help him get to where he wants to be. I also learnt from the readings, mentors do not have to be from the same company/industry, country or gender. One has to be more open minded to new possibilities by working outside of your comfort zone.
  2. To really succeed in the working world, one has to search for many mentors as possible. This helps you gain more skills from different areas. For example, you can be learning networking from a particular mentor whilst also learning another area like software programming from a different mentor. With that you are gaining a lot which does not limit you to a particular field or area.
  3. You need to choose very carefully when selecting a mentor. You don’t want to waste all your time learning things that will never be useful in your career. Also while carefully choosing for a mentor, one has to be sure he is very comfortable with the mentor.
  4.  As time passes on, your life evolves, your needs change and the desire for a new mentor may become apparent.  However, the mentors that helped you grow and prosper should never be ignored. Though you may now have different mentors, the relationships you formed with those from the previous chapters in your life must remain active.

From the readings, I got the understating i need not to rush in getting a mentor. When choosing one, i have to be very careful. I should not limit myself to only one mentor but to learn from many mentors. In that case, at least i gain a bit of knowledge in every field. One particular thing that interested me was “Passing along what you have learned from your mentors is one of the ways in which you can begin the transition to journeyman status.” From, i come to understand that in order for me to get to the top or to be a master, i have to also search the knowledge i have gain to others.

Practice, Practice, Practice

Practice pattern:
You will learn by making mistakes and it is inevitable. How would you purposely make mistakes while on the job? This pattern suggests in order to do so you must find a mentor and have them hand you a task you are not comfortable with and move forward from there. Practice your skills and make improvements each time.

George Leonard says, “The people we know as masters don’t devote themselves to their particular skill just to get better at it. The truth is, they love to practice—and because of this they do get better. And then to complete the circle, the better they get the more they enjoy performing the basic moves over and over again.” I couldn’t agree with this quote more. Over the years we have completed numerous projects and learned many methods on solving problems we encounter while completing these projects. Over time we developed the skills of analyzing the way we go about writing code and fixing bugs without even realizing it.

10,000 hours. That is the amount of time it takes an individual to truly ‘master’ something. Now will that be the case for us? I wouldn’t say so to an extent due to the changes in technology but basic skills like planning, designing, problem solving and debugging would definitely improve given we put hours into working on these skills. The author also makes a very good point when he says practice does not make perfect if you are practicing the wrong skill over and over. There must be changes to improve on that skill each time one practices it.

Journey into A Different Road (A Individual Apprenticeship Patterns)

On this Software Development Capstone journey part of my assignment is to choose 10 Individual Apprenticeship Patterns out of 35 patterns among Chapters 2-6 from the book Apprenticeship Patterns: Guidance for the Aspiring Software Craftsmanby Dave Hoover and Adewale Oshineye. For my first individual Apprenticeship pattern I have chosen A different road. I will first summarize the pattern and then I will state my reaction of this pattern.

A Different Road summarized

After using Draw Your Own Map pattern and creating the map which you been following. You come to realized that the map you drew has led you away from the long road or the road your on is no longer the one for you. Even if you decide to take a detour and do something different from software development your software craftsmanship will always benefit you no matter what. Also, if you do leave and then decide to come back you will be bringing back with you new set of skills that will be beneficial because it will be a fresh new set of eyes with a new prospective. Although sometimes when you take a break some software organization might make you jump over a few hoops and ask you over 21 question seeking justification from you for leaving for a while and then deciding to come back.  The key is to no worry because you are a software craftsmen and everything you have learned will always be with you. An action you should take whenever you no longer want to be a software developer or you’re wondering what would/should you do? This pattern suggestion for you is to list the kind of jobs you would like to do and then find people who matches your jobs list and who also loves their job. Once you found that person you are to “Ask them what they love about it and compare that to the things you love about software development.”

My Reaction

This pattern helps you not worry and be confident that the road although different is not entirely different. It also, reassure you that its okay to take a different road. I agree with this idea. I found that this idea is not just interesting but also useful and thought-provoking. This pattern has definitely changed the way I think about my profession and the way I think I will work because it has made me less worry and more confident in knowing that I should not be afraid to go on different roads because as a software craftsman I will have a set of quality that will last a life time.

Thank you for your time. This has been YessyMer in the World Of Computer Science, until next time.

No hand holding

For the first week of apprenticeship pattern readings, I chose to read Draw Your Own Map. This pattern focuses on the career path that you chose for yourself based on your future or current employer. It tells a tale of how employers can only lead to a limited amount of career opportunities from your current job status. To work through this system, it is necessary to create a plan or road map for your future endeavors after moving forward from where you currently are. By lining up paths that can be available to you based on your current desires, knowledge, and expertise. It will be easier to find yourself in work that suits yourself the best instead of settling for less. These roadmaps should easily be updated to your current situation whenever you see fit. The overall idea behind this is that no one will be able to tell you how your career will end up, everything is up to you.

What I found interesting were the two short stories provided near the bottom of the pattern which clearly showed how reality will present itself. By providing evidence of how some apprentices feel about their current work experience, realizing what they actually wanted, and making a rather small but big step towards their dream career path is inspiring. It also goes to show that not all companies will have their interests aligned with their employees. Also, the action listed at the bottom is helpful to show that. By mapping out from each job choice and their potential benefits and paths that could open or give an overview of how you will end up later on. By not limiting your choices and have a willingness to redo the diagram until you are satisfied with the end result. There is a big possibility you will find happiness at the very end. Otherwise,  I enjoyed the fact that this pattern is straightforward with budding apprentices like myself. As quoted, “Understand that it’s not up to your employer, your career counselor, or your professors to give you a hand up.” Every decision lies in us, by having a plan, you can reduce the amount of roadblocks you will hit along the way and make more informed choices in your career path.

Apprenticeship Patterns – Confront Your Ignorance

Confront Your Ignorance discusses how to begin mastering gaps in your skillset that are relevant to your daily work. It is important to fill these gaps in whichever ways work best for you. For example, some people like to read introductory material until they have a good understanding of the basics, while others like to dive right in and learn by breaking things. Working with peers who are trying to learn the same skills will help you make better progress. Once you have a decent understanding, you must decide whether it’s more useful to dig deeper or start filling other gaps in your knowledge. There can also be negative side effects created by this pattern. If you implement an extremely complex system just to learn how to do it you can burden your coworkers and introduce unnecessary costs. It is also important to not let your education get in the way of delivering a product. A software craftsman must be willing to put the wider interests of the community before personal benefit.

I think that this pattern is very relevant because everybody eventually runs into ideas or techniques that they know nothing about while everyone around them seems to have them mastered. Knowing how to pick which skills are worth learning and being able to learn effectively are important traits required for success. Being able to confront your ignorance is something that everybody (especially software developers) should be comfortable doing.

While I agree with everything written in this pattern, I don’t think there is anything exceptionally thought-provoking about it. It’s basically another way of saying that you should continue learning throughout your career. I believe that this is an important thing to do, but there was nothing written in this pattern that will change the way I work or think about the profession. Overall I think that the content in Confront Your Ignorance is agreeable but I did not take away any new ideas by reading it. I do look forward to reading some of the other patterns that were linked in this one as they seem like they have related ideas that expand on what was written about in this pattern.

“The White Belt”

This is the first Apprenticeship Patterns Blog Posts, I choose “The White Belt” in the second chapter, it represents maintaining a beginner’s mind regardless of your expertise. This is the second chapter of book “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman” by Dave Hoover and Adewale Oshineye. The young philosopher- “Can’t you see the cup is already full and overflowing?”. The more experience you already have, the more effort you will need to put into “emptying your cup,” meaning the more you learned the more you have to “emptying your cup”. We must be humble, to able to thrive and get to next level.

To able to have new mindset new skills, sometimes we must go back “The White Belt” to unlearn what we had learn. I thought this pattern is interesting, this help us how to learn new thing and our attitude go about it. Once we learned language, specially first language, we have pride in out skill. Although it is good for you have confident, if you want to learn new thing. In our mindset, we will try to relate to what we had learn. Sometimes that make we learn new thing much harder. To solve this, “The White Belt” suggest that we find an opportunity to unlearn something, like as we go back and wear white bell as beginner. You have to learn new language, with new structure as you first time learning the language. I have to agree on this pattern on this, we need to learn new language and new functional way of building. I need full attention into learn first, once I understand fully then I could compare what I have learn. Although I don’t have a large library of language, this technique will help me in my profession. This also would help me in career, it is good to know someone who do thing different than you. They will make you understand and learn from them.

Apprenticeship Pattern – Be The Worst

The apprenticeship pattern “Be The Worst” refers to the situation where you’ve outgrown your team and possibly your entire development organization and now you’re no longer learning at a rate that is acceptable to you. The solution to this is the find another group made up of developers where you are the weakest member so you have more room to grow. The quote used in the article to represent this is “Be the lion’s tail rather than the fox’s head!” Another quote that emphasizes this idea is “If you’re the smartest person in the room, you’re in the wrong room.”

I think that while it’s true that being surrounded by developers who are smarter or more experienced than you will definitely accelerate your growth or learning, if everyone followed this idea then the “junior” team members wouldn’t have anyone above their experience level to learn from because they would have already moved on to greener pastures. That being said, everyone doesn’t follow this pattern. There are likely many experienced developers who are happy with the level that they’re at and have no interest in switching teams giving less experienced members of their team a mentor to learn from.

Reading this pattern hasn’t really changed my mindset, as it bears some similarities how I had already thought about my intended profession, albeit a little more extreme. While I agree with the pattern as it refers to switching teams when you feel like you’re no longer growing, I feel that it can potentially be an unhealthy mindset to have. I think a better mindset would to start looking for new opportunities once you’re no longer satisfied with your work. The wording here is very similar to the original pattern, however it also takes into account those who enjoy their jobs, even if they might not be learning as fast as they could be had they joined a new team.

Overall, while I’d say that following this pattern would likely accelerate your growth, I don’t think it’s the be-all and end-all solution to a successful and rewarding career. Being the “smartest” person in the room doesn’t mean you have nothing to learn, especially when it comes to learning how to be a good mentor.

Hexagonal Architecture

Today I am going to discuss one of the software architectures: Hexagonal Architecture. Its purpose is to reduce the amount of time we need to maintain and modify the code, in order to improve the maintainability. The more we increase the maintainability, the less work is required to achieve the tasks. This software architecture is not called “Hexagonal” for no reason. It is actually represented by a hexagon which is very flexible, and it allows you to make changes anytime, because of the independent layers. Each side of the hexagon has an input, an output, and a domain model. The three components of a Hexagonal Architecture are Domain Model, Ports, and Adapters.


Since the Domain is placed in the middle of the hexagon, it makes the Domain the center layer of it, which works independently in the architecture. Also, the Domain Model is used to maintain all the business data and the rules related to that data.

Port is the way to get to the business logic, or in other words, it serves as an entry point. There exist primary and secondary ports. The primary ports are functions that allow you to make changes, and they get called by the primary adapters. The Secondary ports are the interfaces created for the secondary adapters, but other than the primary ports they get called by the core logic.

Adapter serves as a bridge to connect the application and the maintenance that is needed for this application. A primary adapter is an essential adapter which connects the user and the core logic through a piece of code. It might be a unit test for the core logic. A secondary adapter is an implementation of the secondary port (interface).

I found this article interesting because the writer knows who the audience is and explains everything in detail. Also, the topic is related to our CS-343 class and this might be a good start to get into the world of software architecture. Nowadays, we are looking for simplicity and flexibility and this is what Hexagonal Architecture is about. According to the article that I chose the benefits of a Hexagonal Architecture are:

– Agnostic to the outside world

– Independent from external services

– Easier to test in isolation

– Replaceable Ports and Adapters

– High Maintainability

Apparently, Hexagonal Architecture makes the work easier and more efficient, based on this article:
