Eight versions of a self-organized criticality model showing a 50x performance increase

Be curious and kind whenever possible.

Imagination & Logic: recent consulting projects.

Resume that's probably way too long. A longer (and older) About page.

Occasionally I write articles at learnmaketeachshare.org. Here are five I think are especially worth sharing.

1. Learning something new can make all the difference (learning).
2. Imagining what could be (programming).
3. A hybrid guitar-dulcimer-mandolin (experimental luthiery).
4. Making nose strips for people sewing masks (gave away over 29,000 in five months).
5. Shiitake inoculation parties (learning together).

Elm is a purely functional reactive language that compiles directly to JavaScript. Learning Elm was wonderfuly mind-warping! To dig in a bit deeper I created an implementation of the 2048 game: stepheneb.github.io/elm-2048. This really deserves its own article.

Experiments pushing JavaScript performance

• JavaScript computational model and visualization: 50x performance improvement ¹
• 2D molecular and thermodynamic modeling and visualization

Over 200 contributions to open source projects.

Highlights of skills (see resume for a much longer list).

• Web, desktop, and mobile application development
• Raspberry Pi and Arduino software and hardware development
• Sensors, analog and digital design
• Ruby, JavaScript, Python ...
• Rails, Electron ...
• MySQL, Postgesql, Redis ...
• Automated deployment to AWS and a bit with Heroku, Vercel, Netlify

Note: recent projects using Java and Rails are in private repositories. See Imagination & Logic for descriptions and screenshots. Also there are some very large older Rails codebases that are not showing up here because the repositories appear to have been deleted.
