Property-Based Testing in a Screencast Editor, Case Study 2: Video Scene Classification

Recently, I published The Monospace Web, a minimalist design exploration. It all started with this innocent post, yearning for a simpler web. Perhaps too typewriter-nostalgic, but it was an interesting starting point. After some hacking and sharing early screenshots, @noteed asked for vertical alignment, and down the rabbit hole I went.

My goal is a minimalist editing experience, tailored for exactly those tasks that I do regularly, and nothing more. In this post, I’ll give a brief tour of my...

Lately I’ve been messing around with Python 3.12, discovering new features around typing and pattern matching. Combined with dataclasses, they provide support for a style of programming that I’ve employed in Kotlin and Typescript at work. That style in turn is based on what I’d do in OCaml or Haskell, like modelling data with algebraic data...

Quickstrom uses linear temporal logic (LTL) for specifying web applications. When explaining how it works, I’ve found that the basics of LTL are intuitive to newcomers. On the other hand, it’s not obvious how to specify real-world systems using LTL. That’s why I’m sharing some of my learnings and ideas from the past year in the form of blog posts.

In the last post I shared the results from testing TodoMVC implementations using WebCheck. The project has since been renamed Quickstrom (thank you, Tom) and is now released as open source.
