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/

STEM Stuff
PhET - University of Colorado Boulder

β€œPhET provides fun, free, interactive, research-based science and mathematics simulations. We extensively test and evaluate each simulation to ensure educational effectiveness. These tests include student interviews and observation of simulation use in classrooms. The simulations are written in HTML5 (with some legacy simulations in Java or Flash), and can be run online or downloaded to your computer. All simulations are open source (see our source code). Multiple sponsors support the PhET project, enabling these resources to be free to all students and teachers.β€œ β€”PhET About page

Alice

β€œAlice 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.β€œ β€”Alice Home page

Encouraging Girls in Math and Science – What Works

A guide to provide teachers with specific recommendations for encouraging girls in math and science that can be carried out in the classroom without requiring systemic change. Other school personnel having direct contact with students, such as coaches, counselors, and principals, will also find the guide useful.

ProjectCSGirls (ProjectCSGIRLS.com)

β€œProjectCSGIRLS 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!)
