Is it a pint?
Years of countless pours led me to the question “Is this really a pint? They say so, but really?” The findings gave rise to the Pint Patrol, a grassroots movement that could change how Americans are served their beer, wine, and cider—toward righteous honesty. This article documents the initial discovery and the inception of the […]
Show HN: Threadprocs – executables sharing one address space (0-copy pointers)
This repository contains experimental code for thread-like processes, or multiple programs running in a shared address space. Each threadproc behaves like a process with its own executable, globals, libc instance, etc, but pointers are valid across threadprocs. This blends the Posix process model with the Posix multi-threading programming model, and enables things like zero-copy access […]
If Dspy is so great, why isn’t anyone using it?
4.7M DSPy monthly downloads 222M LangChain monthly downloads For a framework that promises to solve the biggest challenges in AI engineering, this gap is suspicious. Still, companies using Dspy consistently report the same benefits. They can test a new model quickly, even if their current prompt doesn’t transfer well. Their systems are more maintainable. They […]
GitHub appears to be struggling with measly three nines availability
Scarcely a day goes by without an outage at a cloud service. Forget five nines – the way things are going, one nine is looking like an ambitious goal. GitHub has had a rough month so far. On February 9, Actions, pull requests, notifications, and Copilot all experienced issues. The Microsoft tentacle admitted it was […]
Migrating to the EU
Posted on 2026-03-22 Introduction For various reasons, I have decided to move as many services and subscriptions as possible from non-EU countries to the EU or to switch to European service providers. The reasons for this are the current global political situation and improved data protection. I don’t want to go into the first point […]

White-Collar AI Apocalypse Narrative Is Just Another Bullshit
Here is an exercise in critical thinking. According to Dario, “two years ago AI was at the level of a smart high school student, now it’s at the level of a smart college student“1. Customer Support market must be obliterated by now? Except it is bouncing back since the middle of 2025 and is now […]

Intuitions for Tranformer Circuits
In a previous post on language modeling, I implemented a GPT-style transformer. Lately I’ve been learning mechanistic interpretability to go deeper and understand why the transformer works on a mathematical level. This post is a brain dump of what I’ve learned so far after reading A Mathematical Framework for Transformer Circuits (herein: “Framework”) and working […]
Migrating the American Express Payment Network, Twice
If you tuned in to Monster Scale Summit this year, you may have seen our talk on migrating the American Express Payments Network – not once, but twice — with zero customer-impacting downtime — meaning no transactions were interrupted and no planned maintenance windows were required during either migration. The session focused on how we […]
