Apprenticeship Patterns – Sweep The Floor

Hi everyone and welcome to another CS 448 Software Development Capstone blog. Today blog topic is about one of the individual apprenticeship patterns which happen to record what you learn. I wanted to read more about this pattern because I can relate. Ever since last semester I been writing many blogs and didn’t fully understand why I was posting them. At first, I thought this method of recording what I learn was to help us research more information and writing them as blogs would help us understand the material better. After reading this, I realize that it’s just more than blogging once per week. I understand that recording our journey helps keep vital resources, makes our journey explicit, and can be helpful to many others. I feel like after reading this individual apprenticeship pattern I will change the way I work because all this time I was blogging, I didn’t really blog for purpose and just blog because it was assigned so I think I will be more efficient when I blog now. I also picked up a new idea from reading this pattern which is to have two journal that is private and public. I can use the public for sharing what I have learned and gaining feedback and the private one for me, to be honest with my status in programming. I do agree that it best to have both because of the perks that each offer. I like when the record what you learn pattern state that Dave was constantly posting his journey for years and eventually, he had tons of resources that he then later uses later in his career. The reason why I like this statement is that it makes me more motivated when posting these blog assignments because I know that eventually, it will come in handy one day in my career. All in all, I felt like this individual apprenticeship pattern, record what you learn is very informative. I learned that every apprentice should keep a journal for their journey and try to write every day as one day it will help others and even help themselves.

Learn the basic

Hi everyone and welcome to another CS 448 blog. Today blog is going about study the classics which is one of the apprenticeship patterns by Adewale Oshineye, Dave Hoover. This blog is a simple pattern which helps me understand the importance of learning the basic. This pattern is about constantly updating your knowledge about the field and making sure you have a strong foundation on the field. After reading this apprenticeship patterns I realize that I should ask where the sources of information are coming from when trying to understand a subject from a person. Most of the time when I don’t understand something that is being talked about, I usually just ask the individual to explain the details in more depth but now I understand I should ask the person where they had discovered the information so I can learn it. I think the biggest problem I have with advancing my skills in programming is that I don’t read enough. After reading this pattern I decided I going to make a reading list to further my knowledge in programming. I like how the pattern points out that there a reason why the classic books are kept and are important to learn. This change the way I judge classic textbooks and now I more interested in them. Most of my books are updated so I haven’t look at any old books yet but I disagree with this pattern a little because some of the books like programming books always have to be updated so the classics wouldn’t apply but I can see other books like theory having classic book that can still relate even in today times. All in all, I think this apprenticeship pattern study the classics is important to the pattern because it explains the importance of understanding the classics while using modern tools. After reading this article I learn to read more, and I change my view on reading. I always feel like watching videos and doing projects was enough, but I now realize that you have read more of both classics and modern book to further my knowledge in the programming field.

Reflecting on “Apprenticeship Patterns” – The Deep End

Overall, I consider myself a person who tends to enjoy my comfort zone. I appreciate settling into a routine, whether this routine appears in my part-time job or is reflected in my academic projects. But is remaining stagnant the best decision for me, going forward into my career? Probably not, considering that I want to grow in knowledge as I gain more experience in the field. This week’s apprenticeship pattern, called “The Deep End,” provides more insight about how I can nip stagnancy in the bud, so that I can break away from a more comfortable routine and challenge myself further, becoming more confident in myself and my skills at the same time.

The problem that The Deep End aims to solve is one that I’ve started to already describe. As I spend more time in my career, I may become concerned that establishing a more mundane routine (like sticking to familiar projects which keep me in my comfort zone of work) is not the ideal choice if I want to continue to improve my skills.

In order to fix this issue, I need to jump into the deep end. To do this, I should seek out projects or other opportunities that are challenging enough that they are straying away from my comfort zone. I need to also understand that this sudden change to more difficult work can come with risks, including the possibility of failure. This balance of striving to test myself with different, tough tasks, while keeping an eye on my progress so that I am not in over my head, must always be maintained. If the likelihood of “drowning” continues to increase, it is also essential that I have the capability of reeling myself back in and find help if needed.

I completely agree with everything this pattern encompasses. Even though it would be nice for me to remain comfortable with the work I am doing, I know that it is imperative for me to continue tackling difficult problems and projects so that I can remain at the top of my game and keep my skills fresh.

Thanks for reading!

Diving Deep

This series explores Apprenticeship Patterns by Adewale Oshineye and Dave Hoover. This week, I decided to read the apprenticeship pattern “The Deep End.” 
To be completely honest, most career opportunities that are on the horizon are somewhat intimidating. I wonder if I have the ability to do a lot of the work they require. The chapter talks about getting into a rut, but my rut is working fast food. Making a transition to a career-oriented position is a big step, and it is a bit out of my comfort zone.
Instead of reluctantly accepting a task that I am not confident about, I should have the self-assurance to jump in at the deep end. This gives me permission to take on a task that might seem daunting when it presents itself. This is easier said than done, and I find it hard to entirely  abandon my initial timidness.
It is important to note that they also warn about getting too far out of your depth. It is okay to jump in the deep end, but “you still need to remember that if the water level is above your head it means you’re drowning.” This is key. They offer two other patterns for helping with this, which is “Finding Mentors” and “Kindred Spirits.” The titles seem descriptive enough to give a general sense of what you might need to look for. Perhaps one of these will be the topic of a future blog post to dive in more in depth.
The action it suggests is to measure the biggest projects I’ve accomplished based on a few factors of complexity. When the next project comes along, see how it compares. It claims this is a good indicator of where my career is heading, and it might be the basis of choices I make.
Already, when thinking of mapping my projects like this, I think to myself, “I need to do more independent projects.” I’ve done quite a bit for school, but I haven’t done anything incredibly ambitious on my own. I have vague goals of what I want to do, but I have done few concrete steps to fulfill them.
Most of my goals for independent projects are somewhat formidable at this point in the game. For example, I would like to make some sort of a web app that I would have to develop full stack. I have a few ideas in mind for what to do.

MINIX3: Scheduler Research II

I’ve had to change my approach the past week or so with this independent study. When confronted with the source code, I think I began to feel overwhelmed by the amount of concepts I had to dive into. As a result, I attempted to take it from square one and relearn many systems concepts while also working on understanding the scheduler. As it turned out, this was a bit stressful for me. So I have decided to instead look at the relevant source code and, line by line, take notes learn things as they come. Perhaps this is the traditional way to handle diving into a large system of work, but since I don’t have a large amount of experience in large-scale work this is a learning process for me. It seems that this new direction is working a bit better for me.

Let’s start with /minix/servers/sched/main.c. The main() function is the primary function of the scheduler. When a message is passed into the scheduler, the main() function defines variables for the message, system call number, the caller’s number, and the result of the system call. Then, it enters an infinite loop. This loop saves the message’s info in the variables that were defined for it, and then checks for special situations such as system notifications, etc. (I’m not totally positive on the function of that, but it says that the balance_queues() function is called in this event.) Then, based on the call_nr (the system call number), a switch statement determines what call from /sched/schedule.c should be executed next, with functions like do_noquantum() (which executes when a process is out of quantum) and do_start_scheduling() (which seems to start the scheduling of the process). So long as the process is executed correctly, a reply is sent back that communicates success, and the loop continues on to the next kernel message.

So hopefully soon, I’m actually going to start tinkering with the scheduling policy and see what I can come up with. In the scheduling report I discussed in my previous post, it was suggested that with the current interface a Round Robin, Priority Scheduling, Staircase Scheduler, or Rotating Staircase Deadline algorithm can be easily implemented, so I’ll learn one of those and aim for that. I’m sure it’s going to take me longer than just a week to fully implement, but we’ll see what kind of magic I can work. I’m also sure I’m going to have to write a couple more of these research-related blog posts before I fully understand the workings and can proceed forward, but having changed my plan of attack, I’d like to finish those this week. Ready to move forward once again!

Every little bit helps!

For the sixth week’s reading, I chose to read the pattern, Sweep the Floor. This pattern focuses on a problem where you are a new apprentice on a project. The real-world experience of joining on a team means that you have to learn about the team and the team has to learn about you. These situations are uneasy and earning the trust to contribute to the development that they have worked on before you joined is a problem to be solved. The solution provided for this is to start contributing to the project by completing tasks that the other members do not want to do. Examples provided do not entirely mean that it has to be about coding and could be other tasks such as code review, setting up a project wiki, or updating documentation. As long as you contribute to the team, they will have an easier time and appreciate your work and build trust. The objective is to build enough trust that you can take on bigger challenges and eventually become one with the team.

What I found interesting about this pattern is the excerpt in the second to last paragraph. It is the last thing a student that is about to graduate from university would want to hear. Completing your tertiary education, after spending the four years or more getting the degree, accruing massive student loans to hear someone devalue your education is heart wrenching. However, those who chose the route of getting a degree should be fully aware that this is the reality. The knowledge you gain from school is like a baseline for real work experience. Being accepted to work at a place does not automatically mean you are on the same page as everyone else. You will have to spend time as a newbie and learn about everything the company, team, or workspace has to offer.

This pattern has not changed the way I think about the profession or how it will work because everyone has to start from somewhere. As someone fresh out of school should realize that education doesn’t mean all that much when compared to actual experience in the field.

Craft Over Art

When I read Apprenticeship Patterns, the patterns which tend to stand out to me the most are those patterns which offer a unique perspective and an illustrative focus that is clear and easy to follow. Oftentimes when I am deciding how to proceed with my learning or implementation of code, I get lost in the possibilities, and the guidance the authors provide in this book gives me some much needed clarity.

This apprenticeship pattern is called “craft over art”, because the point of our vocation is to in the end provide a useful product to customers. The value the authors place in this section is on the practical and usable skills that makes up a good developer. The authors illustrate this point well by reasserting and contrasting what it means to be a software craft-person.

At its heart, craftsmanship is making something useful or necessary with an additional style or beneficial features that are added based on the creator’s methods. The authors definitely make this point clear when comparing software development to a craft, and even more so by comparing crafts with the arts. The key difference is that while crafts focus on making a functional product, the fine arts are focused on pure beauty itself.

So what the authors suggest we focus on as apprentices is not the beauty of the product but the functionality of it. Additionally, they describe how often in practice in order to deliver value in time a compromise might need to be made between utility and beauty.

This pattern definitely helped me hone in on which particular skill sets and goals I should be orienting myself around to be successful. Often I worry that I need to be focusing on making the most elegant code or learning the newest fanciest technology, which are definitely good things to aspire for, but in the moment of me beginning my professional journey, it is more important that I pick up practical, concrete skills, and that I focus on delivering the most value and utility. What I gained most from reading this was understanding that bells and whistles will make a product shine, but you famously cannot polish a turd.

Confront Your Ignorance

For this week’s blog, we will talk about confronting your ignorance from the Apprenticeship Pattern book. This will be a continuation from the last blog Exposing Your Ignorance.

Now that you have let your teammates know that you are lacking in some skills, it is now time to deal with your ignorance. There are tools and techniques that you need to master but you do not know where to begin. Some of them are things that are expected knowledge from you that everyone around you already knows.

So what should you do?

The book’s solution is to pick one skill or tool and actively fill in the gaps in your knowledge about it. How should you do it is up to you. Whatever works best for you. For some, the best approach is reading all the introductory articles. Others find that looking at the code is a better way to understand it. They also recommended asking around if anyone is also trying to master these skills or ask a mentor that already have these skills and if they are willing to share what they learned.

I find this chapter interesting since it was tied to Exposing Your Ignorance chapter. To do this pattern, you will need to expose your ignorance first. Using this pattern in isolation might lead to a culture where failure and learning are unacceptable and everybody just keeps to themselves. Also, your employer has certain expectations from you and might not be understanding of your educational needs that would get in the way of the successful delivery of its project.

Confronting your ignorance is probably one of the things that you will be doing over and over again in your workplace. Most likely, your first few months in the job would be a learning curve for you. Figuring out what tools they use, how it works, and how you could use them would be the first challenge you will face.

This pattern changed the way I think about confronting my ignorance. Usually, I do everything alone and try to solve things alone. But that seems like a band-aid solution to the problem. It is better to ask people who have mastery of such skill and see if you are doing it the right way, so in the future, you will be more knowledgable and can be a master of this skill as well.

Apprenticeship Patterns – Kindred Spirits

The Kindred Spirits apprenticeship pattern is about how you need to keep in contact with people who are on the same path as you in order to continue learning and growing your passion. This is important because you may find yourself working in an organization that does not encourage software craftsmanship and does not provide mentors for you to follow. Working with a community provides an environment for exploration and learning that is not as intimidating as working with a mentor. However, when you are working with a community you must continue to think for yourself and not just blindly follow along with what everybody else is doing.

I thought that this pattern was very useful because keeping in contact with peers is one of the most important things that you can do if you want to stay passionate about software craftsmanship. I’m sure that many people find themselves in jobs where they are programming very boring things and start to forget whey they had a passion for software in the first place. If you are in contact with similar people, you can learn about and explore new ideas in a relaxed environment. This will allow you to continue growing and nurturing your passion even though you may be stuck in a job that is stagnant and uninteresting.

I enjoyed reading the two examples about people who followed this pattern because they showed how people were actually able to connect with each other and keep in contact to become kindred spirits. I also think that the recommended action of listing all communities that you could potentially join and going to each is a good idea. There are probably many communities around me that I may be interested in but have never discovered simply because I haven’t sought them out. Reading this pattern has definitely inspired me to find communities to join because now I realize how important it is to be in touch with other people in the field, especially after graduating college. Overall I think that this pattern is very useful and I don’t disagree with anything that was written.

Breakable Toys || S.S. 6

Sams Ships (7)Recently, I have been seeing plenty of messages along the lines of “We learn from failure, not from success.” As someone who used to regularly watch all of Casey Neistat’s vlogs from the beginning days, it is something that has been ingrained in me to take risks and know that if I fail, then at least I did not give up and allowed myself to try.

When I saw the Breakable Toys apprenticeship pattern, I thought this would be the perfect opportunity to discuss trying things! This pattern is basically trying to explain to us that you need a safe space to learn something even if you work in an environment that may not allow for failure. It encourages us to seek our own way to sharpen our skills and take initiative, which would increase our confidence.

I found that this pattern is thought-provoking because where would you be if you did not take all the risks or new experiences beforehand to get to where you are today? I used to study biology and chemistry until I gave computer science a real chance. It was a little daunting at first to catch up but I made it (so far). If I did not take on leadership opportunities when given the chance, would I have the observation skills I have today when it comes to being involved on a team? Probably not!

If you do not allow yourself to try something out or practice something, I think you would feel a lot more pressure. It was reassuring to hear that someone like Steve Baker also experienced something like that, which makes it a lot more normalized.

As kids, we started learning how to interact with the world by playing with toys and developing our own sense of physics. Through that, we took risks like throwing things, sliding things down places, and etc., until we figured things like “oh, maybe I should not have accidentally thrown that ball too high and it went to the neighbors yard!” But at the same time, you’re a little proud that you’ve gotten better at throwing the ball harder.

That’s the same thing with developing yourself in your professional career. I will allow myself some time and space to learn something without that pressure and it may surprise me, once again, how far I may go.
