Expose Your Ignorance

This week I read the section called Expose Your Ignorance. This sections is something i can relate to very well. I am a senior in college and by that time many people would think that you would be able to program thing by yourself.  You should know about at least 2-3 languages by now and have the knowledge to work in the real world however just like the section “White Belt” there are always going to be people better than you and you don’t know everything yet. It is still a learning experience and for me in the class that we are taking now the section we are doing for the project. Which is encryption services is still something I don’t know much about at all. Just saying that you know nothing about something would be better then you hiding and saying nothing. That is what a team is about. To help and encourage each other to do what you can do and that way you can help them when they need help. During hackatons that i go to when meeting new people if we wanna work on a project we all have to introduce ourselves to each other. We also have to tell people what we can and can’t do because if we depend on someone to the most important part of the project and they don’t have the knowledge to do it in the end we would not have a project to present. Also just because you don’t have the knowledge to work on the project you should not just sit around and do nothing. Take this time to learn a new language, download the library’s needed to work on the project, watch videos, and work with a project partner to see if there is anything you can do. Just like the section says people are more inclined to make themselves look competent then just to tell others that you don’t know what you are doing because there are people looking up to you for advice or employers looking to you for the knowledge. That is why this section teaches you that you that lying about knowledge inst worth it and to accept your faults and work on them another day.

Data Flow Testing

Finally, for this week I decided to write about Data Flow Testing. I found a blog site called Ques10 and there was a question about what is data flow testing. The blogger Ramnarth ansered the question by explaining what Data Flow Testing is. Data Flow Testing is a test that tells us that a programmer can perform a number of test on data values which are collectively known as data flow testing. With data flow testing it can be performed at two levels static and dynamic. Static testing is performed by analyzing the source code and doesn’t involve in running the source code. It is performed to reveal potential problems in the programs which are also known as a data flow anomaly.  And with dynamic testing it looks at the path of the program from the source code and with this you would draw a data flow graph of the program select a critical testing area, then identify the paths in that data flow and test the derive inputs. He talks about how testing critical section on the data flow chart by breaking it down into paths and tests such as how we did it in class. Were we would look at the DU-Paths and look at all the edges and nodes to see if they make sense. I like this blog because it does involve some of the things that we did in class such as DU-Path testing, edges, and node testing. I like that the things I learned in class is also reflected into real life things we can do. I think data flow testing is just something we could be doing because it is just a bunch of tests that you run through so that way you do multiple test at the same time.

 

 

Don’t Repeat Yourself (DRY)

Source: https://dotnetcodr.com/2013/10/17/the-dont-repeat-yourself-dry-design-principle-in-net-part-1/

For my last week I decided to write about Don’t Repeat Yourself design principle. I found a blog called dotnetcodr and there was this blog about (DRY) written by Andras Nemes where he talks about (DRY). The idea behind (DRY) is that you should not add repetition of logic in multiple places in the code. He talks about the motto that you should be following “Repetition is the root of all software evil.” Repetition does not just refer to writing the same piece of logic in two different places but also the repetition testing, debugging, deployment, ect.

He then gives an example of repetition where he writes out the person and then where the live as well. In this code he hard codes everyone’s name and address. This way it is a very good example of reputation because since he is just copy and pasting whenever he would need to add or remove a person or address he would have to go back into the code and manually change it himself.

I found this blog to be very informative because it is very true you do not want to repeat yourself and the logic of a certain code in multiple places and multiple times. There are times where I do this a lot because I find it much easier to repeat the code since it is going to be the same every time I want to call something. I think the thing I get out of this the most is that I will start to try and not repeat myself when writing code. Also I can use this for future knowledge when I do write things that do call things multiple times and like it shows in the blog we can make stings that have getter and setters that would make a 40 line code down to a 10 line code which would save much more space and time as well.
