Computer Science Educational content including programming in C++ and Java, algorithms and data structures, and concepts of programming languages. The majority of this content was originally developed for the benefit of my students at my former university, but I have posted it here in hopes that it will be useful to others seeking to learn. I have chosen to take an early retirement, but am continuing to create videos that I hope will be helpful to those seeking to master software development and computer science concepts. The Linked Lists Drawing Tool linked below is a program I created to help students learn linked lists. Note that it is not mobile-friendly.
