My father passed recently, and he was twice my age.

After a number of Twitter discussions, and repeating myself a lot in these discussions, it is time to write a short note on the economics of advancing LLM capabilities through RL, about principles of propaganda and coining new words, and about my stubborn…

I have seen a lot of public discussion around supply-chain attacks on the Python ecosystem, prompt injection risks when using coding agents, and general worries about the security implications of “vibe coding” for the development machine.

I recently embarked on a small toy project/experiment: How well can I equip Claude Code to automatically analyze and triage crashes in a C++ code base?

In a series of previous blogposts [1, 2, 3, 4] I ran some experiments drawing the boundaries of the polytopes generated by a fully-connected leaky ReLU network while it was getting trained on reproducing an input image.

In many discussions where questions of “alignment” or “AI safety” crop up, I am baffled by seriously intelligent people imbuing almost magical human-like powers to something that - in my mind - is just MatMul with interspersed nonlinearities.

After the previous blog posts here, here, and here, a friend of mine pointed me to some literature to read, and I will do so now :-).

What is this?

In this post, I will explain my current thinking about neural networks.

Welcome to one of my political posts.

Hey all, I have written about the various drags on the European tech industry in the past, and recently been involved in discussions on both X and BlueSky about what Europe needs.

The last few years have seen a wave of hysteria about LLMs becoming conscious and then suddenly attempting to kill humanity.

While I have been a sceptic of using ML and AI in adversarial (security) scenarios forever, I also quite like the fact that AI/ML has become important, if only to make me feel like my Math MSc (and abortive Math PhD) were not a waste of time.

Hey all, == tl;dr == Today is my last day at Elastic.

This post is an adaption of a Twitter thread where I listed the various factors that in my experience led to a divergence of the trajectories of the US tech industry around Silicon Valley (SV) and the tech industry in Europe.
