CS 145 Lab 1
Welcome CS 145 is a class where you learn to teach machines. You won’t just use them. You’re going to become a developer. Unlike the natural and social sciences, computer science and programming are not topics addressed in many of our schools. Let’s take a moment to describe what we computer scientists do with each […]

Plotting samples with GNU Octave
Suppose we have a plain text file of samples named samples.txt, with each intensity on its own line: We can visualize these results in GNU Octave with: If we write this code in a script named plot_samples.m, we can simply run plot_samples at the Octave command-line.

Levenshtein distance
We’re looking at methods for comparing the distance between two sequences of text. A fairly simple one is Levenshtein distance, which calculates how many edits it takes to go from one string to another. I wrote a little calculator to demonstrate its results. Enter two words and calculate their distance. Cell (i, j) reports the minimum […]

CS 491 Lecture 23 – BThwack
Agenda BThwack We were going to talk about incorporating a two-player Bluetooth mode into Bluecheckers, but it was getting out of hand. Instead, I looked back at the last of apps you folks expressed interest in back at the beginning of the semester. And there is was. Whack-a-mole. But not just any Whack-a-mole, Bluetooth-enabled Whack-a-mole. […]
CS 491 Lecture 22 – Bluecheckers
Agenda case study of making a NDK/OpenGL powered game Bluecheckers A couple of weeks ago I got the latest issue of Make magazine in the mail. On page 56, Charles Platt describes a 2-player Chinese Checkers game. I thought, “That’d be fun on a mobile device.” We don’t have time to code it all from scratch, but […]
