I recently unveiled Earpiece as a playground for exploring how sounds are shaped by their frequency and amplitude envelopes. Today we use it to explore a jump sound. First, close your eyes. Imagine you are holding a game controller. Press the jump button. Wrong one. Try again. That’s right. What did you hear? We can […]

The author, DrPetter, made the tool to support folks like me who don’t have the time, skill, or team to make sounds for their games. But […]
It was my first semester of graduate school. We were in a lecture for CS 530: Computer Architecture. Dr. Ward had two announcements. First, a midterm was coming up. Second, the annual departmental mug design contest was accepting submissions. An alumnus donated money each year to purchase mugs for all the graduating students, faculty, and […]
There’s a pandemic happening right now. At times like this, we get to see both the best and the worst in people. One of the worst things in us is rugged individualism, which leads us to buy more than our share of toilet paper. We were legitimately running low this week, and I grew concerned […]
My son is learning long division at school. He was intimidated by it, so we started practicing for just a few minutes every day after school. The format is simple: I generate two numbers, a big dividend and a small divisor, and he divides them. One day I wanted the quotient to be 99 because […]
America may not have metric, but at least we have hexadecimal. This sign appears near Green Bay in eastern Wisconsin.
