My name is Andy and I make lots of random stuff. Read more about me on the About page.

What's New, You Ask?

I've released a tiny little macOS menubar utility I use to quickly swap my SSH config files between different environments or use cases. It's called Sshwitch.

Side note: On this website, I am using the super-cool Input font for this site. If you write code and you want to use it for your code editor, grab it here: https://input.djr.com/

Alice

“Alice is an innovative block-based programming environment that makes it easy to create animations, build interactive narratives, or program simple games in 3D. Unlike many of the puzzle-based coding applications Alice motivates learning through creative exploration. Alice is designed to teach logical and computational thinking skills, fundamental principles of programming and to be a first exposure to object-oriented programming. The Alice Project provides supplemental tools and materials for teaching using Alice across a spectrum of ages and subject matter with proven benefits in engaging and retaining diverse and underserved groups in computer science education.“ —Alice Home page

PBS Kids Cyberchase

Games, videos, and activities to get kids involved in a science- and math-based adventure to learn and save the universe from evil cartoon characters (it’s hard to believe those cute little characters are evil, but we’ll just go with the story). 😉 There are multilingual activities, as well, FYI.

Resources for STEM & Women/Girls in Tech

Technology is super cool and it shouldn't care who makes it that way. Women/Girls in Tech.

Women & Girls in Tech
ProjectCSGirls (ProjectCSGIRLS.com)

“ProjectCSGIRLS is a 501(c)(3) international nonprofit organization dedicated to closing the gender gap in computing and technology. Our unique idea of a technology and computer science competition for middle school girls stemmed from the fact that a large chunk of learning and development occurs during the critical middle school period.” (See the statistic above!)
