CS 352 Lecture 5 – Makefiles

Dear students, I’ve gotten some emails about homework structure, C++, and Makefiles. I had a completely different discussion planned, but I think our time is best spent addressing your concerns. Today, then, we will create a skeletal C++ project that can be built with a Makefile. You may want to check out a few tutorials […]

CS 145 Lab 2 – Math and String

Welcome to lab 2! If you have checkpoints from the last to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. You must work with a partner that you have […]

CS 352 Lecture 4 – Relays

Dear students, We looked last time at the elements of electronic circuits: switches, voltage sources, resistance, and some sort of output device—in our case, an LED. In putting these parts together in various ways, you can build a piece of technology with a very fixed purpose. If you want the hardware to do something else, […]

CS 145 Lecture 4 – Math Class

Dear students, Yesterday we had our first lab. I was very impressed by your positive attitudes toward learning and the way you helped each other. Lab days are a bit grueling for me, as I am on my feet from 8 AM to 5 PM being relied on by others, but your energy and friendliness […]

CS 491 Meeting 2 – Sketches

Dear students, Most of today will be spent by you giving sketches of your game ideas. Here are some questions to keep in mind as we discuss: How will it be fun? What will be learned? How can the challenges of the game be introduced in chunks? Here’s your TODO list: Your Create Task is […]

CS 145 Lecture 3 – Hello Again, Java

Dear students, We start today with a little segment I like to call What Does This Do?. I show you a short snippet of code, you slurp it into your brain, swish it around a few times, and figure out what it does. The task would be much easier if I picked good meaningful names […]

CS 352 Lecture 3 – Electricity for Computer Scientists

Dear students, Today we step have a look at the foundation of our technology: electricity. Let me preface by admitting that I am no expert in this field. My understanding of this field is patched together through unstructured fiddling; it has many holes and assumptions that threaten its collapse. We discuss it now because this […]

CS 145 Lecture 2 – Hello, Java

Dear students, Last time we peaked into a primary activity of computer science: organizing process. We started this adventure using Madeup, but today we’ll jump into Java, the language we will spend most of our time with this semester and next. Java is a language developed by Sun Microsystems. It surged to popularity because in […]

CS 352 Lecture 2 – Bases

Dear students, Last time we looked at how aliens might encode a message and send it to us. After class I was thinking about the suggestion that they use ASCII. But this would really be quite a leap for them, because the only alphabet that they know that we understand is Morse. All the communication […]
