Given the importance of interpreters it is not surprising there are many implementation strategies. In this blog post I want to discuss one of the main axes along which implementation strategies vary, which is how far we take reification of actions within the interpreter.

In this blog post I’ll attempt to explain the basic ideas behind probabilistic programming. I’m assuming you, dear reader, skew more towards programming than statistics, but are not afraid of numbers. Hence I’ll concentrate more on the programming than the machine learning side of things here.

Scala.js is Important for Cloud Services

More people are using serverless architectures than I would have guessed, and they are getting significant benefits from doing so. Scala is a great fit for these kinds of architectures because it can use the JVM and, thanks for Scala.js, JavaScript runtimes too. This post is a small observation regarding this.
