Computer Science for Middle Schoolers – BOGO Sort, Insertion Sort, and Bubble Sort

Once every couple of months, I get an opportunity to teach middle schoolers/high schoolers about computer science. Computer science and software development are very broad disciplines, so I could cover anything from web styling to computer networks. Among all of those possible topics, I find that I like to work on sorting algorithms.

Git Merging vs. Rebasing: The Beginner’s Guide

Let’s say you’re creating a feature branch off a master for a new feature you are about to implement. You finish up your work on the feature branch while one of your colleagues is making some changes on the master branch. Before creating a pull request, you might want to make sure you have the most […]

Using Angular Content Projection to Draw Smiley Faces

When working in Angular, it’s pretty straightforward to create components and nest those components inside of other components. However, it is a bit more complicated to design customizable components that will display content based on the components passed to them (content projection).

Reactive Programming: A Timed Popup Component with RxJS

Reactive programming is all about streams. It involves combining streams, filtering streams, and transforming streams. In reactive programming, the application does not need to pull for data, but it is notified whenever a new event occurs. A few months ago, I wrote a post on reactive programming in WPF using ReactiveUI. Recently, we’ve been working on […]

IdentityServer Authentication with an MVC Client & Unauthorized Loops

I’ve learned a lot about authentication this past month. My team has been working on migrating an application from using Forms Auth to IdentityServer single sign-on. Our goal is to provide a centralized authentication for all parts of the system.

GOTO Chicago 2018 – Complexity, Boring Languages, and Not Throwing Null

Recently, our group of Atomic accelerators headed over to Chicago for the 2018 GOTO Chicago conference. It was a two-day conference with six different tracks each day, so there were always multiple good options to choose. The talks ranged from machine learning to office politics. Even though the conference did not have a specific focus, there were themes that came […]

Resources for Middle School Girls to Learn Programming

While we were at the Junior Achievement Girls Dream Fair a few months ago, a middle school girl came up to our booth. She went carefully through a sheet of questions, writing down my answers word for word. “Anything else you’re curious about?” I asked when she was done. After a pause, she asked, “Is […]

Reactive Extensions, ReactiveUI, and Whistling Tea Kettles

How does reactive programming work? “It’s all streams,” our program manager explained. “When you update a property in one part of the system, it causes another property in a different part of the system to update, too. It will take a bit to wrap your mind around.” In my head, I pictured properties all over […]

How Learning Software Is Like Learning Chinese

During college, I showed up in Beijing with only a couple of elementary Chinese classes under my belt and took a placement test. It had a “tell us about yourself in Chinese” section. The previous summer, I had painstakingly memorized how to write a lengthy paragraph about myself in Chinese characters, so I wrote most […]

Drawing Shapes with SkiaSharp

My team was working on an activity tracking application and wanted to be able to display segments of time on a radial gauge. When implementing this feature, I initially tried using some libraries specifically designed to build arcs, but I was disappointed by their lack of flexibility. When my pair recommended looking into SkiaSharp, I was […]
