What I Found Interesting in Claude Code's Source

A breakdown of the most interesting engineering patterns in Claude Code's leaked source code: composable system prompts, runtime instruction injection, context compression, forking, prompt caching architecture, and more.

Procedural Tokens — encoding design decisions

Most design tokens hold a value. The interesting ones hold a rule. A live walk from static refs to procedural tokens.

how computers changed the way we write

Code Is Cheap Now, And That Changes Everything | Pere Villega

AI coding agents have made code production nearly free. Drawing on insights from Kent Beck, Paul Ford, and Simon Willison, this post argues that the value has shifted from writing code to defining systems — contracts, invariants, SLAs, and verification.

E.W. Dijkstra Archive: On the cruelty of really teaching computing science (EWD 1036)

The second part of this talk pursues some of the scientific and educational consequences of the assumption that computers represent a radical novelty. In order to give this assumption clear contents, we have to be much more precise as to what we mean in this context by the adjective "radical". We shall do so in the first part of this talk, in which we shall furthermore supply evidence in support of our assumption.

Today I was able to weave a line from Myron Krueger in a talk I gave : Computation is the medium of our lifetimes - it’s not just a technical medium but a cultural medium as well. We should explore the culture of computation.— zach lieberman (@zachlieberman) April 10, 2024

Magicoder: Empowering Code Generation with OSS-Instruct

We introduce Magicoder, a series of fully open-source (code, weights, and data) Large Language Models (LLMs) for code that significantly closes the gap with top code models while having no more...

Random Tech Thoughts

This article is about standardisation, particularly how it relates to understanding code.  I’ll first go into an historical example that highlights the lack of standardisation in an area where we take it for granted today.  After that I’ll get into code, and how understanding code is like understanding data via visualisations.  In both the historic … Continue reading Standardisation and code
