Hi, I’m Stefan Ramson

I developed Active Expressions, a reactive primitive that adds reactivity as a first-class citizen to state-of-the-art languages such as JavaScript, Python, or Smalltalk. You can define an object-oriented expression and get notified whenever any state change affects the expression's result, triggering your callbacks. Based on this mechanism, you can easily write more involved reactive programming concepts. Available in multiple implementation variants including byte code rewriting, dynamic interpretation, and using proxy objects.

An interactive visualization to explore massive hierarchical data structures with relations like software projects with dependencies. Edge bundling provides high-level insights while the interactions allow you to focus on specific parts of your dataset.

I created floom, a fluid simulation written in JavaScript. floom uses the Material Point Method, a hybrid variant of particle and grid systems. You can switch to computational models and change material parameters on the fly.
