Concrete Skills|| S.S. 4

Sams Ships (4)On this weekly individual apprenticeship pattern post, I’m going to discuss Concrete Skills. This pattern is pretty much explained with someone wanting to be a part of a good development team but they have not yet built up their development experience. My reaction to this pattern is that this would be a comforting one for students in college or upcoming graduates (and even entry-level developers) to feel a little less pressure on bridging the gap between starting fresh and being an experienced developer.

Concrete skills are interesting to me because you can have all the knowledge and information but being able to take what you know and apply it to something is different. The main takeaway I got from this pattern is to learn things that you will be able to apply even when you are still in the on-boarding phase. This has caused my to change the way I think about my intended profession because of course I want to get started and involved in projects right away. I like the feeling of being able to help people out when I have down time at my current opportunity just because I get to sharpen up a skill in one area instead of just sitting there.

A good question proposed in the pattern stood out to me, “If we hire you today, what can you do on Monday morning that will benefit us?” It’s interesting to imagine yourself in the role of a hiring manager; they have to hope to understand you well enough so that they can trust that you will be able to do your job and have an impact on the company. This thought makes me want to continue what I’ve been doing in terms of pursuing different learning experiences that will help me become a stronger developer not only knowledge-wise but skills-wise.

I do not disagree with something in the patterns as it gave me something new to think about and look forward to using in my future. I found it useful to hear their advice on considering looking at other CVs as references of what we would like to put on our potential list of skills.

Do You Hate Your Computer Too?

Sams Ships (3)Apparently doctors hate their computers, according to an article titled Why Doctors Hate Their Computers by Atul Gawande. Gawande started out the article by mentioning Epic, a company a lot of people know of because it is a leading provider of software for the healthcare industry. It’s funny because just the other day, a classmate who will not be named groaned when he heard Epic being mentioned by someone, as he works in a healthcare center.

I found the reading was interesting because I have no intentions of becoming a medical doctor one day but was able to hear about how it is being one while interacting with technology that exists today.

It seems like the tension of logging everything caused the system to make doctors’ lives harder instead of easier; this was noticeable when Sadoughi was talking about how she had to look over all notes from different doctors including herself per patient. Instead of being able to just see what is going on right away; it would take up time to gather all information and even then it was not always helpful because some notes were different than others and became dated. And then work-life balance had to be thrown off a little because people had to spend extra time, up to hours after-hours to catch up with the system and review things from the day.

The real customer for the system seemed to be patients because they have some benefits from using the system like logging when to take medications or see how they are doing. Doctors are also able to monitor how they are doing and communicate with them by being pinged.

The lessons from this system do not only apply to Electronic Medical Record systems; they also apply to working in life because burnout can happen to anyone in the workforce. I thought it was interesting how one of the ways doctors were trying to save time and prevent burnout from technology was by hiring in-hospital scribes or even virtual scribes when necessary.

The reading has caused me to changing the way I think I will work based on if I ever end up creating software that affects people’s healthcare by considering how much time it takes to interact with it, no matter how “cool” or “innovative” it may be. In terms of the topic itself, the reading has caused me to think more about software that has altered people’s professions as a whole; which I thought of before but never this deeply.

I do not disagree with anything in the reading for now as I do not personally know what it is like to work in a profession that is not traditionally non-technical and then gets transformed into something that relies on it.

The Deep End || Sam’s Ships S.S.3

Sams Ships (2)On today’s installment of the individual apprenticeship patterns series, we’re going to discuss The Deep End. The main takeaway of The Deep End is that you should throw yourself into an opportunity even if you are hesitating or unsure. Of course, it is not necessarily telling you to be reckless, it also emphasizes how it is your responsibility to offset the risks of your approach.

I found that this pattern was interesting because as a person, I continuously try to say yes to trying new things or taking on new roles when the opportunity arises. The Deep End is basically the pattern that represents that mindset and reinforces how important trying something you might think is “risky” turns into being one of the best choices you ever made.

The pattern has caused me to change the way I think about software development/engineering based on the “action” it tells us to consider; which is learning to see what choices are affecting where our career is heading and eventually learn how to make choices based on it. I will try to focus on not only reflecting and reviewing what has happened but I will also move forward by actively making decisions based on experiences.

I do not disagree with something in this pattern so far as the “risks” I have taken so far have always turned out bettering me as a person or helped me achieve something greater. Things like taking on new roles within Enactus when I was unsure about how much time it would take on top of my already busy schedule to how to actually do things were part of my worries. In the end, it turned out alright because I was able to work things around my schedule and people who knew what the role(s) consisted of were there for me as a resource or form of support.

Overall, I am pretty content with the things I have jumped into because like Enrique from the Jumping in With Both Feet story, I eventually felt “like a fish in water.” I liked being able to read about someone’s success story of an instance where they went after something and thought “hey, the worst thing that could happen is I don’t like it and I fly back.”

QAn’t Wait to See You Again

CS SERIES (16)Before I dive into my final installment of this CS series (for now), I wanted to say thank you if you actually read any of these posts and thank you to my new followers for dealing with the notifications you must have gotten.

For this last post, I wanted to discuss the article 5 Reasons You Are Wasting Your Testing Time by Joel Montvelisky. The author expresses how everyone can do testing but not everyone can do “good testing,” which incorporates more than just what is basic checking.

A short list of main reasons why a lot of people tend to waste time that could have been spent testing other things includes:

  • Not having clear goals
  • Not understanding what or how much the feature means to your End User
  • Not keeping track of what was tested and potential discoveries
  • Not consulting what you already know or using references
  • Not giving feedback that could be shared to help others

Sam CS (22)I agree with most of what Montvelisky says as I have personally noticed what has happened from my experience as a Software Quality Assurance Intern when any of the five things above took place based on a task. It is important to understand that sometimes these things may be out of your control but you should still try your best to avoid miscommunication wherever possible.

Montvelisky’s content has not necessarily changed the way I will work as I have already been consciously making an effort to understand what I am reviewing, how stuff is meant to work, logging tasks, connecting tasks to previous occurrences, and communicating with the QA team. If I had read this article before I started working, it would have been more useful as it would serve as a foundation to how one should think of testing beyond the basic functionalities.

Something I wanted to emphasize is the post-test reviews and feedback sessions with peers. I found that if someone else needed to learn about a project or a task had to be communicated with a client, logging any kinds of notes or information was better than not having anything prepared to discuss. They do not necessarily have to be posted for everyone to access but it would be good to note it in any sort of text editor for future reference. I think an example of when to note things is if you found something that does not prevent your current task from being approved but it still affects something for the overall program.

Overall, when testing things I believe you should trust your instincts on reporting things you find. It helps when you try to imagine how much it could affect a program in the long run if not brought to someone’s attention, even if it may seem minimal.

Best of Luck,

Sam

Test Yourself Before You Wreck Yourself

CS SERIES (14)Testing, testing. I may need your approval on this article I read by Software Testing Magazine on Approval Testing. Approval testing, as defined by this article, is a way of software testing that results in presenting the before and after of an application for a user (ex: software development team) to review it and potentially approve it. It’s more of a visual representation of testing and one of the major cons is how the results have to be checked manually.

Some testing tools mentioned include: Approval Tests, TextTest, Jest, Recheck, Automated Screenshot Diff, Depicted (dpxdt), and etc.

The main purpose of the software testing tool, using TextTest for example, is checking that the text output after running program from the command line in different ways.

What I found interesting is how a user can see that a test technically could have “passed” or “failed” but still decide to mark it as the other because they choose what feature they are looking for in the end. This makes it a little more flexible to use approval testing as it is more of a guide or guideline for a user instead of only seeing one word and then a short description of what could have gone wrong. I think this process is much more transparent or descriptive with a user about what could have gone wrong or what went right.

One way the content has changed how I will think about the testing is how there are so many more types of software or programs out there than we can imagine which help us better code or create our own software and programs. This one is especially good for visual coders and testers who like to see their results firsthand to compare what they are expecting with what they actually got.

Overall, I found this article was useful because it introduced me to thinking about a better way of logging the differences between what the reference result is versus the actual result. I did not disagree with any of it since it showed us how we can use approval testing to our advantage while still being honest about its limitations.

Top 5oftware Architecture

CS SERIES (13)When using architecture patterns, how will you know which one to choose? Peter Wayner, an independent author for TechBeacon takes five architectures that the majority of programs today use and broke them down into their strengths and weaknesses. Through this, it seems like he is hoping to guide users to selecting the most effective software architecture pattern for their needs.

If this article does not clear up enough information, Wayner also brings up a book, Software Architecture Patterns by Mark Richards, which focuses further on architectures commonly used to organize software systems.

The fives types discussed in the article are:

  • Layered (n-tier) architecture
  • Event-driven architecture
  • Microkernel architecture
  • Microservices architecture
  • Space-based architecture

The one I found most interesting is space-based architecture because at first when I thought of space, I was thinking of the other kind. The one with the sun and the stars and the moon. But then I realized–what does that have anything to do with software architecture? Space-based architecture is listed as “best for high-volume data like click streams and user logs” and I think this one is pretty important, especially during times like Black Friday and Cyber Monday. I personally experienced the frustration of not being able to access a site (adidas) due to high volume and it really does not help a business.

Another architecture I found thought-provoking is micro-services architecture because of the way Wayner introduced the concept, “[s]oftware can be like a baby elephant: It is cute and fun when it’s little, but once it gets big, it is difficult to steer and resistant to change.” The author providing an example of this made me think about how a site with so many users and things happening at once actually just had many different separate services but they were put together as one. I was a little surprised to think of Netflix in that way after all the times I’ve used it but it makes much more sense now.

Overall, I found all of the information pretty useful and clear to understand as Wayner described what they were and then listed the caveats and what they were best for. I would recommend using this as a reference or quick review of common software architecture designs if someone needs it.

Software Blog

CS SERIES (12).pngThere are lots of “rules” we must follow in object-oriented software development and the article The Genius of the Law of Demeter by Javadevguy summarizes how they are useful. From what I put together, it seems like the Law of Demeter took abstract concepts and basically put them into a universal set of rules for Object-Oriented code.

I thought that the law of demeter must be a big deal if someone decided to sit down and write a lengthy blog post about it. This content ended up being interesting as it tried to convince readers why they should obey this “law.” The Law of Demeter basically paves the way for what users can do to a given method. It is kind of like considering the restrictions or possibilities based on the method. One of the takeaways I got from this is how there is a lot of focus on communication between two objects.

The rules listed in the article are as follows–noting that it says “For all classes C, and for all methods M attached to C, all objects to which M sends a message must be”:

  1. self (this in Java)
  2. M’s argument objects
  3. Instance variable objects of C
  4. Objects created by M, or by functions or methods which M calls
  5. Objects in global variables (static fields in Java)

Another useful takeaway I got from this article came from observing the code examples Javadevguy included; how Rule #1 covers that any method can be called on the current object. I also noted when there would be an instance where the law would prohibit something is not “sending a message” to any already existing object that is held in instance variables of other classes.

This will affect the way I continue to do work as an Object-Oriented developer. I mean, in life when you learn there is a more useful or structured way to help you achieve more effective results, you would want to try or follow it, right? For my future use, I will acknowledge (like other blogs and articles) that the Law of Demeter is less of a law and only a suggestion or a guideline.

Overall, I would say that the content has helped further solidified my understanding of some Object-Oriented coding concepts. I agree with the content as it is trying to help people become better developers or better understand the Law of Demeter in general.

Is Your Interface Two-Faced?

CS SERIES (11).pngWhen coding, users always have to be conscious about the way their code may be implemented or used in the future by different services leading to potential misuse. After reading Code Health: Make Interfaces Hard to Misuse by Marek Kiszkis, it made me think about how important communication between testing code is.

I found this content useful because Kiszkis featured some examples that can show how an interface could be misused easily. The examples included:

  • Requiring callers to call an initialization function
  • Requiring callers to perform custom cleanup
  • Allowing code paths that create objects without required parameters
  • Allowing parameters for which only some values are valid, especially if it is possible to use a more appropriate type

Sam CS (17)It is also good to remember that at the end of the day, code should be defensive but not too defensive to the point that complexity is increased and performance overall is reduced. Kiszkis says “it is not always practical to have a foolproof interface” because there will be situations where some requirements are things that cannot be expressed in an interface.

After seeing so much content based on being careful about what you code it is surprising how this article says it is not necessary to plan too hard. I kind of understand why Kiszkis would say this but personally, I kind of disagree with this. The reason why I disagree is because if someone does happen to end up with more time to work on something than expected and they know it will make something more efficient, then why not go for it?

Overall, I appreciated what was shared in this article in terms of encouraging users to try and see issues that can arise with their code when it comes to interfaces. The main takeaway for me is that if something is brought up, or triggered by undefined behavior, a user should try and make it impossible for this to happen. A way of doing so is by adding things where necessary, like certain slots in his example. It does not have to be too specific but detailed enough so that it covers different aspects, similar to how we try to prepare for everything when it comes to equivalence class testing.

test | prueba | thử nghiệm

CS SERIES (10)If you happen to be reading this page translated from English to another language, hello there, you are one of the main characters of this blog post. Without linguistics, the study of language and its structure, we probably would not be able to figure out how to communicate everything we need to globally while being able to understand it at the same time while testing. There are so many online resources that cover what a specific country or region in a country uses in terms of data formats for their computer systems.

Stickyminds featured an article from Mukesh Sharma on Linguistic Testing: Setting Up Your Software for Global Quality. Sharma dives in by explaining what exactly linguistic testing is–which is testing not only localization but also internationalization. These words basically mean everything we are testing on the software either is or would be fully functioning across the globe.

I found this content thought-provoking as I never specifically thought about how developers and testers would have to consider culturally-aware attributes like the formatting for texts, dates, and currencies. As more and more people are gaining access to the internet across the world, that means there are even more and more platforms to test for gauging market readiness.

An example of a situation that could happen in real life I can think of when testing functionality on websites is for international shipping addresses. If a user, we’ll call him Zayn, from London, England is ordering something from a company based in Boston, Massachusetts (USA) and puts in his shipping address, it should not require him to select a “State” under one of the fields after he selects “United Kingdom / England” as his country option. If that field still requires Zayn to select a state when his country location does not have states, there is a problem.

This will change the way I think when I work as when developing code to solve problems or create something new, I will have to think about if the market or target audience goes beyond the USA. When testing the code, of course every possible scenario must be tested already but there will have to be more details to make sure it all goes smoothly–especially since international errors or problems usually take up more effort to fix as communication plays a big factor.

[W]in Tech

CS SERIES (9).pngOver the weekend, I had the chance to sit down and listen to another podcast episode by Developer Things. The title, Women in Technology (with Megan Horton), caught my eye as I am always on the lookout to learn about other women’s experiences in technology.

The podcast series’ goal is for people to learn new developer things each time they listen so here’s what I learned on the career side related to software construction, design, and architecture:

  • The stigma of “nerds” begins in elementary school so girls start to stray away from STEM even in the limited amount of programs there already are for computer science in earlier education years. This eventually results in the number of females in CS in universities–like mine–is so low along with the numbers of those who move onto the software development workforce.
  • There are jobs out there like writing software for watering fields based on whether the sun is up or down or varying weather conditions. It reminded me a bit about how we used duck stimulator as an example to learn UML diagrams and had different actions performed for each duck.
  • Career advancement is not always a straight path. People tend to switch into computer science as a major or switch into technology when they want a career change. I’d like to point out how the host of this episode took the opportunity to say Horton came from the funeral business to killing software bugs.
  • You won’t always have to write code: there’s so much out there–you could have a passion for anything and do something tech-related in that setting.

The content has caused me to think more deeply about what I will do in technology, I mean of course I’m going with software development or software engineering but what is the overall goal throughout my career timeline going to be? What kinds of companies will I end up working for? What projects or passions will I follow along the way? Overall, I enjoyed the podcast with Horton as she discussed the ups and downs of being a female in technology and her experiences in the industry so far.

I don’t think I was there for the time when people would be kicked off the internet because someone needs to use the phone as discussed in the episode but I do experience times when my connection isn’t consistent. It really makes me sit back and think about how technology relies on constant power and a steady internet connection.

A major takeaway that I continue finding myself writing about is how we will always be learning something new in technology as things are always changing–as long as the power is on.
