Then I dive into the tutorial we held about Oxidised OCaml, the performance-oriented fork at oxcaml.org that @yminsky.bsky.social announced earlier this summer. Try the tutorial in a convenient devcontainer, and take our quiz to help develop the language! @thenumb.at anil.recoil.org/notes/icfp25...

We've seen how to define and apply Monte Carlo integration, but there's a whole world of techniques for reducing variance. Part five (thenumb.at/QMC) covers Quasi-Monte Carlo: negative correlation, stratified and adaptive sampling, and low-discrepancy sequences.

I had a lot of fun giving this talk in Singapore about the many-years-long saga of multicore OCaml, and in particular, the work over the least 2.5 years of getting it ready for production work within Jane Street's walls. www.youtube.com/watch?v=XGGS...

I am getting increasingly excited by the runtime metaprogramming extensions coming into OxCaml. They deal with the fundamental non-portability of most of the modern vector extensions in CPUs (across all architectures), but don't expose any of their decision trees in the interface of the OCaml lib

Rendering nerds! Check out our latest work "Vector-Valued Monte Carlo Integration Using Ratio Control Variates" that has just gotten the best paper award at SIGGRAPH 2025. This paper presents a method that reduces variance of a wide range of rendering and diff. rendering tasks with negligible cost.

Monte Carlo has many uses, but path tracing is one of my favorites. Part four (thenumb.at/Rendering/) explores how Monte Carlo integration is used to simulate light transport.

Max Slater @thenumb.at · 12/04/2025

Monte Carlo methods require randomly sampling complicated domains, which can be difficult in of itself. Part three (thenumb.at/Sampling/) discusses how to create samplers using rejection, inversion, and changes of coordinates.

Monte Carlo integration lets us integrate high-dimensional functions exponentially faster than traditional methods! Part two (thenumb.at/Monte-Carlo/) explores how and why it works.

Functions are vectors! This perspective lets us apply the tools of linear algebra to computational problems from image and geometry processing to machine learning and light transport—and provides a natural explanation for Fourier series. Let's explore: thenumb.at/Functions-are-Vectors
