This apprenticeship pattern talks about how software developers should stay in the trenches. As software developers gain experience, they tend to gain a reputation for being exceptional at delivering software. Many organizations tend to reward with promotions in the hierarchy. However, such promotions might end up leading apprentices away from their craft. This pattern elaborates how apprentices should not confuse promotions into management with success. Being promoted might seem like a good sign that you are on the right path, however, one should understand that they will not remain a “technical” manager for long.  A craftsman who strays from their craft will have their mastery over it fade. The more time you spend not programming, the further away you are moving from being a journeyman.

If an apprentice wants to remain in the craft, then they need to draw their career map accordingly. For example, one could try to discuss with their employer the possibility of finding different mechanisms which they may find rewarding. This could come in the form of higher compensation, or it could come in the form of nontraditional technical leadership roles such as internal consultancy. In the case where the employer is inflexible, then perhaps it might be best to look at other opportunities elsewhere. This way you will remain in the craft and prevent yourself from being promoted away from it.

I personally think that this apprenticeship pattern is useful for people with a specific set of values. It is useful for anyone who values their passion for staying in software development and wants to stay active in the craft. If you are someone who loves software development and want to continue However, some people might value things like status, compensation, and greater responsibility more than remaining active in the craft, and therefore, going into management might be the right move for them. Since different values can lead to different career paths, it is important for software developers to constantly reevaluate their career map to see whether the path that they chose is aligned with their values and circumstances or if they need to consider a different path.

This week I would like to look at the “Confront Your Ignorance” pattern. I feel like this is always a good one to look at as despite how good of a programmer you might be, there is always something more to learn, and there is always something you don’t know.

This pattern means there are things you still need to learn/know, and some of these things are things that many others may already know, so it is expected of you to also have this knowledge.

I feel like it is always important to confront your ignorance, as there is still much to learn, even when you have seen a lot. This pattern is very similar to the “Expose Your Ignorance” pattern, but this one is about learning in private, so you do not need to hurt your pride by making others aware like in “Expose Your Ignorance”. However, it is still important to know to expose that ignorance as well, since always learning in private can have some negative side effects, like having failure be unacceptable instead of just another step of the learning process. You need to be able to learn and grow in a way that will positively affect you and those around you.

But should you choose to not learn in private, a great way to confront the ignorance is to ask questions, as many people may have already had the problem you are currently facing, and are hopefully happy to help you overcome the issue. A common cause of ignorance is focusing too heavily one one particular skill or context, which causes you to become ignorant of the other skills. One must be able to learn, and identify the areas of ignorance, and actively work towards reducing those areas.

You must also always be able to admit your faults, in this case admit that your knowledge is lacking, as how will anyone know your knowledge is lacking unless you tell them? This way, everyone can work together to achieve better learning. Of course, it may hurt your pride in the short term, but it is always better to be known for your willingness to learn more, than to know a lot about a few things.

The authors of the Apprenticeship Patterns book do an amazing job of capturing my attention. The opening quote that the “Practice, practice, practice” pattern starts off with demanded that I pay attention to what comes next.

“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—“

When I read this quote part of me shimmers with hope because of the proper guidance I was just given to help make it in my future, and another part of me frets because practicing can be difficult and I don’t want to struggle or face the hardship of practicing. Now my issue with practice isn’t that it can be difficult, I don’t mind taking on a challenge. My issue with practice is that I don’t want to be practicing but doing it completely wrong and then feel like I have been wasting my time. The way I picture it is like doing a bunch of push ups but the entire time you’ve been doing them your back was “U-shaped”. You don’t know any better until someone comes along and tells you that you’ve been doing it wrong the whole time. Meanwhile you’ve “mastered” the U-shaped push up but in reality there is no such thing. All the arm strength and muscle memory you built to do that unrecognized form of exercise was for naught, and that’s how I feel I might end up when practicing alone. The pattern does recommend practicing in public places, doing “kata” or finding a coding dojo to code amongst others and have these flaws pointed out as you practice. This sounds like something that would cause my nightmare scenario to never happen but there comes this slight embarrassment when thinking about asking for help or making a mistake in front of others… I suppose it’s a small price you pay while getting better. After all, its better than the former scenario. An old manager of mine once said something to me that still sticks with me today “If you ask once, you’ll only feel dumb once. But if you never ask, you’ll feel dumb forever”. Perhaps I should do more than just think about the profound words and apply them.

Surprise, you probably wont. Lets back up a step first though and talk about what that acronym actually means. YAGNI stands for “You Aren’t Gonna Need It” and is an important acronym to consider for software development applications. I heard about YAGNI from our class, and I wanted to know more about what exactly it consists of, and what its purpose is. Thats where I found a good article by scaleyourapp.com, which did a good job explaining it. In its essence, YAGNI means that you shouldn’t create something until its actually necessary for your application. After all why would you want to waste time on things that might not ever be needed. As many people who have written code know, we often write a function/class expecting to need it in the future, only to never actually use it. This in turn leads to wasted space in the program, wasted time writing the unneeded code, and now you have to think about whether you should bother keeping it or just dump it to save space. I have plenty of personal experience with this in my own projects and work. One particular example that comes to mind is that during a 36 hour hackathon last spring, my teammate and I spent many hours trying to figure out a good way to incorporate a login/user tracking system into the app we were writing. While this feature would EVENTUALLY be needed, for the sake of creating a basic proof of concept app it was far from crucial. Because we didn’t use YAGNI principles we wasted time that could have been spent doing any of the other myriad of tasks we had to do for the rest of the app. These several wasted hours resulted in us not being able to add other needed features, and as such the app was not as complete as it could have been given the time constraints. Even before hearing about YAGNI as an idea, that experience left my partner and I with a realization that there are much more efficient ways to approach writing code than what we attempted. Since then I have been much better about not writing useless code until its needed; however I still have instances where I create a function or class that realistically doesnt need to exist. It can be difficult sometimes to figure out what is needed and what isnt, especially at the beginning of a project. I always assume I am going to need one feature or another, so I begin write it; only to find out a little while later that its not really that important at the moment. While I still started writing it, I have gotten better at stopping before I go too far and waste too much time. That way I can spend more time and energy focusing on more important aspects of the program I am writing.

This week I decided to dive more into APIs in general, not just RESTFUL APIs. So let us start at the beginning. API stands for Application Programming Interface, and it is an interface with a set(s) of functions. These functions allow programmers to use specific features or data of an application. A web API is an API that is accessed over the web, like through the HTTP protocol. The web API is a framework that assists in creating and developing HTTP based services.

An API usually works as follows, the client application initiates an API call, usually to retrieve information. This call is also known as a request. This request is then processed from the application to a web server using the API’s Uniform Resource Identifier, and usually has a request verb, like GET or POST, for example, headers, and a request body. After receiving a valid request from the application, the API makes a call to the web server. The server then responds to the API with the requested information, and the API then transfers the data to the initial requesting application.

APIs are often used for many reasons. This includes, but is not limited to, improving collaboration, offering easier innovation, data monetization (as money makes the world go round), and added security. APIs enable integration such that platforms and other applications can easily communicate with each other, allowing easier automation, therefore improving collaboration. They also offer flexibility, allowing connections to new businesses and reaching new markets, offering easier innovation. APIs are also often offered for free, usually initially, to allow the developers audience to grow so they can build relationships with their audience of developers around their brand for the future, securing future business partners, thus offering data monetization. Lastly, APIs create an added layer of security between your data and a server. Developers can also choose to add further security measures like tokens, signatures, and Transport Layer Security encryption, just to name a few.

There are also many types of APIs, some of which include, but are not limited to, SOAP, or Simple Object Access Protocol, XML-RPC, which is a protocol that relies on XML to transfer data, JSON-RPC, which uses JSON instead of XML for its work, and REST, which we have covered in prior weeks blog posts.

I decided to use the above source for this weeks blog post because they provided a ton of good information about APIs in general, and IBM is also a very well known company and therefore also a good reputable information source.

This week will be continued talk on APIs and specifically I wanted to learn more about the structure of our API’s including on the differences between frontend and backend and any extra information on API’s that can be included. I have chosen a website that goes over what exactly these are and gives a good amount of information that could be useful later down in our careers.

In summary, frontend and backend are two very popular terms in web development. The term frontend is usually used for the part of the website that the user directly interacts with like the GUI’s. This is also called the “client side” of the application and use languages that should sound familiar to you such as HTML, CSS, and JavaScript with JavaScript being the most popular language of them all. This is because of several advantages such as flexibility, speed, and extended functionality although it does have some disadvantages in areas such as with debugging. Now if the frontend is what the user interacts with, the the backend should be everything that is kept out of sight from the user such as work with the databases, the scripting, and the API itself while making sure it can connect to the frontend. The languages used include python, PHP, and java all being widely used. The work on the frontend and backend has also become quite specialized over the years in which it is usual for one person to either work with just the frontend or just the backend and people who work on both are called full stack developers.

This resource has given me insight on the work we are doing with the API’s and with the work we are doing on the backend. The work that we are doing with the databases and the API’s is an entirely different area from the frontend that we haven’t even touched yet. The areas that have to be learned are numerous that require different sets of skills and talents to work in. It makes me wonder on whether we will get to work with the frontend in this class or in a future class. The I should prepare myself a bit more if one would want to become a full stack web developer seeing the needed skills in both ends. Although I haven’t done much work on any frontend material so I would have to wait to see on what the experience is like when working on the frontend on deciding if I should focus on one or another in the future.

This week I read a blog post that I thought really related to the class about agile software development. The blog is about the phases of the agile software development lifecycle. The blog starts off explaining Agile and why it is used. It is being used because of its flexible, iterative, and incremental character. The blog then goes into the phases, and some agile techniques and tools. The phases are requirements, design, development and coding, integration and testing, implementation and deployment, and finally review. Some of the tools and techniques are spiral SDLC, and waterfall SDLC. The blog then goes into the pros and cons of agile software development. A pro is that there are flexible working hours around the clock, and a con is that all communication takes place on the internet, so it might be harder to connect with fellow developers. The blog ends by summarizing the cycle of agile software development, and describing it as aiming to build and deliver flawless working software on a tight schedule.

I selected this blog post because software development is my dream job, and I thought it would be interesting to read about a possible way I might be working using the agile method. This blog has a great way of showing how agile software development works, and how useful it could be, and I think every CS major should read it since we have to take another class similar to the things in this blog with software process management.

 I think this blog was a great read that I recommend for many reasons. One reason I would recommend this blog is because of how deep it goes into explaining the cycles of agile software development . The blog gives a description for every phase, and explains what to do at every phase, what others are going to do while you are on that phase, and what tools to use when you are on the phase. Another reason I would recommend this blog is because a lot of jobs that we will be looking for in the future will be using the agile method, and if we are not good at using it, then we are at a disadvantage to be hired. The last reason I would recommend this blog is because it is focused on teamwork, and teamwork is important for every job, and not just computer science related jobs. Agile could be used anywhere. 

This blog taught me about all the phases, and that if they are all done correctly by a team of developers, they could really work productively as a cohesive unit. The material affected me heavily because it showed me what skills to learn, and what to expect if I want my future dream of software development to come true as many jobs might be using the agile method, so I must be prepared. Now that I know about the agile software development method, I will try to look for more different methods.
