First bee sighting of 2026 Honey bee on Waterloo bridge I was crossing the Waterloo bridge to go to a seminar when I saw my first bee of 2026.

Nice strange attractor visualisation Strange attractor visualisation using THREE.js Zensical is a new static site generator implemented in Python that I heard mentioned on the Talk Python to Me podcast.

Draft: Evolving interactions with AI in 2026 My 2025 year in summary according to ChatGPT Living through the first couple of weeks of 2026 it is clear, whether I like it or not, that it will be yet another year dominated by AI.

A little snippet for nicer plots using matplotlib If you’ve seen previous blog posts (or read any of our group papers) you may have noticed the plots have a consistent look. import seaborn as sns from matplotlib import pyplot as plt The default matplotlib…

3D-printed mathematical lampshades Finished lampshade I’ve been playing with translucent PLA for lighting projects at home.

Using uv projects on a network share The wondeful uv has a strong preference for virtual environments that are placed within a project tree rather than kept centrally a la conda.

Reparameterizing distributions in numpyro Every single time I’ve tried to “chance” it with probabilistic methods I am once again reminded that you can’t treat them like a black box.

Live variational inference This is mostly to show two possibilities: The ability to update the data going into a model in the course of running variational inference.

Amortized probabilistic models for chemical microscopy Can we used an amortized model to speed up inference in our droplet microscopy model?

Trialing generative processes for chemical microscopy (part 2) Last time we used a very rigid generative model (droplets modeled as gaussians).

Trialing generative processes for chemical microscopy (part 1) Is it possible to use a generative process to model microscope images like this (and is it worth the effort?)

Simple generation of locally constrained values in numpyro Just a simple experiment using numpyro to simulate values from a function with locally constrained values.

A rant against macros I used to be a huge fan of macros.

The case for lazy computation and interactive optimization Since 2018, my colleague Dario and I have been working on a probabilistic model of chemical reactivity.

Fertile land at the confluence of staged programming and (typed) logic programming — Part 1 I recently started sketching out a logic programming library called Logic.jl (it really is very much a sketch at the moment).

Funny … Likewise, claiming JS is homoiconic because you can eval strings of code is nonsense.

A new way of doing chemistry I’ve been thinking about a new way of doing chemistry.
