How and Why I Built Attendence Calculator
I'm a student in my senior year of a Computer Engineering program. I started coding in my first year, for the first time, and found it very intriguing because technology always fascinated me.
The problem I wanted to solve
In engineering, there are always issues with calculating how many classes can be missed and still result in a pass so that one can manage both academics and other interests.
What is Attendence Calculator?
A webpage (live now) that calculates how many misses you can have or how many classes you have to attend to have a desired attendance percentage.
I used Excel DAX first, because that was the only thing I knew.
Then, C because it was the best thing I knew.
The process of building Attendence Calculator
I figured out the algorithm during some tutorial physics class that I was not interested in.
In the beginning, I didn't know any language. I just knew some DAX syntax for Excel formulas, which I learned in my fifth class. So, I programmed in an Excel sheet that calculated and predicted how many classes to attend or skip to attain a desired attendance percentage.
I made a webpage using those and gave it to friends to provide me with feedback. They said it was too complicated.
Finally, I made it really minimal and simple to use. I then signed up for free hosting and a domain to finally upload my site.
Challenges I faced
I didn't know any specific language when I started — just the algorithm.
You don't need to have expertise in some language to create something useful. It's always the algorithm that plays the main role.
Tips and advice
- Just start as soon as you get an idea.
- Always listen to people's needs.
- Build something first and then keep improving it.
- Try keeping it simple to use.
Final thoughts and next steps
I am trying to get my college to add this module to their official website so that more people can use it via a common medium and access the college attendance database.
