This is our second week in CST 383 - Introduction to Data Science. Pandas This week we discussed Pandas , which is a Python library that is built on top of NumPy and is designed for data analysis. Series  First we discussed Pandas Series, which is analogous to a list or 1D array.  Series are made up of two 1D arrays. One array contains values, and the other contains indices for the data. The two arrays for values and indices can contain different data types. To create a series we use  pd.Series , such as  x = pd.Series([.2, .4, .3, 1.0], index=['Mon', 'Tue', 'Wed', 'Thu']) . If no index is explicitly given, the Series defaults to standard indices (0-length - 1). We can also create a Series from a dictionary by passing the dictionary into  pd.Series . For example, if we had the dictionary  d={'Mon':0.2, 'Tue':0.4}  we could create a Series with  x=pd.Series(d) .  In the above example, the values  ['Mon', 'Tue', 'Wed...

This was our first week in CST 383 - Data Science. This class discusses machine learning, how to analyze data, and how to use Python for data analysis. Python Array Operations In this week's video lecture we discussed various operations one can perform on python arrays. Slicing:   Python arrays can be accessed using [start:stop:step]. Start defaults to 0, stop defaults to the end of the array, and step defaults to 1. For example, to access the last three elements in an array we would use array[len(array) - 3:], to access the first half of the array we would use array[:(len(array) / 2], and to access every other element we would use array[::2]. Fancy Indexing:  We can use an array as a list of indices we want to get from a different array. For example, array[[0, 2, 4]] would return the first, third, and fifth elements of the array. Broadcasting:  We can perform operations on arrays to quickly perform operations on each element in said array. If we have the array [1, 2...

Service Learning Project Throughout CST 462S I performed QA for LibreOffice . This involved reviewing user reported bugs, attempting to reproduce the bugs in LibreOffice, asking for additional information if needed, and updating the status of the bug when applicable.  The project was a good experience overall. Before starting the project I was unfamiliar with QA. Both the site itself and my supervisor provided plenty of resources that helped prepare me for performing QA. After having finished the project I feel much more comfortable performing QA for LibreOffice, and I am confident that I could perform similar tasks for other sites or services. The service project was not without its own troubles. One thing that I consistently found difficult was the complexity of many of the bug reports. Many bug reports referenced advanced aspects of LibreOffice or had bugs that were complicated and obtuse. Some days it was easy to find reports that I felt comfortable tackling, while other days i...

C.R.A.P. This week we learned about C.R.A.P., which is short for Contrast, Repetition, Alignment, and Proximity. It is a set of guidelines for graphic and UI design in video games. It emphasizes different elements being clearly distinct from each other, readable, consistent with elements of similar types, and not being too crowded or sparse.  Game Menu Redesign This week we took a menu from a video game and redesigned it in a different style. I chose to take Balatro's UI and try to redesign it in a portrait orientation. Redesign: Original:  

This was our first week in CST 328-40 - Digital Art and Design. Photoshop This week we discussed some of the basics of using Photoshop. As part of an assignment I edited the following picture of Jupiter: Here is the edited version. I added more contrast and slightly edited the colors of the red spot to make it stand out. Reading This week we read a handful of articles discussing graphic design. Understanding Pixels and Resolution This article discusses pixels, pixel count, ppi and dpi, pixel depth, and how to resize images in Photoshop. 10 types of image file extensions and when to use them This article discusses raster and vector images and several common file formats. What Is a Mockup and Why Do We Need It This article discusses what a mockup is and why, when, and how we use them. What are Prototypes? This article discusses what prototypes are and why, when, and how we use them.

 This was our first week in CST-462S - Race, Gender, & Class in the Digital World. Service Learning Project The largest portion of this course is going to be the Service Learning Project. In this project we will be doing 25+ hours of voluneering for one website from a list of available ones. The available websites and projects range from helping high school students with a project, to helping develop on open-source software. For my service learning project I will be doing QA and bug testing for LibreOffice , which is an open-source alternative to applications like Microsoft Office. Outside of bug testing my own code I have no experience with QA. I am both excited and nervous for this project. It will be challenging, but I think it will be valuable, hands-on experience. I am set to meet with our LibreOffice representative this upcoming week to plan out my service learning project, and I will be starting it the following week. Research Topic Groups Another major portion of this c...
