For this week’s blog on Software Architecture and Design, I will revisit the same assignment that I have blogged about before. For the assignment, I had the option between three design patterns to write a tutorial for. I picked the proxy design pattern, and then I blogged about the decorator design pattern. Now, I would like to watch a tutorial on the third design pattern, facade, so that I might learn about all three. I chose to use the same YouTube, Derek Banas, that I used before for the other blog. I found his videos engaging and informative that I would like to learn about it again. I also like that it is fairly concise (11.5 min), which makes it much easier to rewatch sections that I don’t get the first time around.  It turns out that I did not understand it after finishing Derek’s video, so I turned to another video by another Youtube channel by Christopher Okhravi. Derek went straight into coding, whereas Christopher just drew diagrams and did not code. I needed m...

For this week’s blog on quality assurance, I wanted to review what we learned most recently in class. I decided to watch a relatively short (24 min) tutorial on Mockito. It has been over a week since I’ve seen it, and there’s another few days until we meet again. I could use the refresher before then. The tutorial I chose to watch was by a YouTuber named Walter Schilling. I thought he explained the concept very well. I will definitely bookmark his page for other concepts that I find challenging. I thought it was a little bit of a complicated set up. I don’t think it was necessary to see the UML diagrams or as extensive of a walkthrough of how his code worked. He didn’t go excessively in depth, but I understood it pretty well after he gave a  demonstration of the final code in action. (He typed in some inputs and showed what the output would be.) I didn’t need to know as much information on his example code. That’s not what I had come to see. When he got to the mockito section...

For this week’s blog for quality assurance and testing, I decided to read an article from Wired Magazine that focused less on the testing process itself and more of how a company can benefit from it. The article I chose is a little less than a year old about Apple’s securities and vulnerabilities. The article confirms some of what I had hoped — that Apple still has a strong reputation for security. However, some vulnerabilities have damaged how the company is perceived by many.  In High Sierra, all that you had to do to gain root access was type the word “root.” They fixed it impressively quickly. However, the article wonders if the security flaws like this are emblematic of deeper problems. There have been many more bugs and vulnerabilities found, such as wonky autocorrect on the iPhone. Although not every bug (like the autocorrect) is not always a security issue, it is incredibly irritating.  One advantage that Apple has over its competitors is that most of its cus...

For this week's blog on Software Design, I decided to watch a short tutorial on one of the design patterns I didn't pick for a previous assignment. I picked Proxy Design pattern to cover before, and now I'm going back to learn about Decorator Design Pattern. It is only a thirteen minute video, so I won't be going as deep as I would had I picked it for the assignment. I am also going to talk about my reflections on it rather than create a tutorial, so I am not going to reteach it to the person reading this blog post. The tutorial I chose was made by Derek Banas on YouTube. He used an example of a pizza parlor to illustrate the wrong way to code it by using inheritance. He shows the problem with this because you would have to create a very large number of subclasses for all your objects (in this case pizzas). Composition, on the other hand, is a dynamic way of modifying objects. Instead of creating as many subclasses, you add functionality at run time. It has th...

I decided to take a somewhat different tack for this week’s post for software quality assurance and testing. Instead of focusing on testing itself, and all there is to it, I found a video from a tester in the field, Alan Richardson, on his advice for someone who is interested in getting into the field. He strongly urged someone getting started not to think of a position in quality assurance as a “stepping stone” to being a software developer. If you do, you will inevitably find yourself in a dead end because you really aren’t interested in the field. “If you want to be a software developer, start as a software developer.”  He encourages the viewer to read everything they can on the subject. A lot of it is free, so there is no reason to necessarily buy anything. However, he gives some book recommendations. He gives a good insight why books can be so valuable to learning. “An expert in the field took a year to concentrate everything they know into those pages,” (paraphrased...
