TL;DR: Tesler’s Law, the conservation of complexity, says a system has an inherent amount of complexity that can be reallocated between owners but never deleted. The useful move is to split that into …

Laws & Disorder #3 — Tesler's Law: You Can't Delete Complexity, Only Choose Who Owns It
Stop Guessing Which Coding Agent to Use — Benchmark It on Your Own Tasks
TL;DR: Generic coding-agent leaderboards don’t tell you which model or tool fits your work at a budget you’re willing to spend. So I built a small task set that mirrors my real work and ran an open-so…
The Quadratic Wall: The Algorithmic Race to Beat O(n²) Attention
TL;DR: Standard self-attention costs on the order of n² in the sequence length n, in both arithmetic and the attention-score memory it materialises. Almost every long-context architecture headline of …
Laws & Disorder #2 — Hyrum's Law: In the Age of Agents, Who Pays for a Broken API?
TL;DR: Hyrum’s Law says that with enough users, every observable behavior of your API becomes something someone depends on, whether you documented it or not. The implementation quietly becomes the int…
From Robot Soccer to the Agentic World Cup: Why Games Move AI Forward
🎬 Also available as a blog walkthrough video: a narrated screencast of this post. TL;DR: Twenty years ago, a year-long university project group I was part of built a team of soccer-playing cube robots…
Why AI Tokens Are So Expensive — and What Actually Makes Them Cheaper
TL;DR: Autoregressive LLM generation has two phases with different bottlenecks: prefill processes input positions in parallel and is usually compute-intensive, while decode produces tokens sequentiall…
Laws & Disorder #1 — Conway's Law: Your Org Chart Is Your Real Architecture (and AI Is Redrawing Both)
🎬 Also available as a blog walkthrough video — a short narrated screencast of this post. TL;DR: Conway’s Law says a system’s structure ends up mirroring the communication structure of the organization…
Post-Quantum Crypto Is Here — What It Means on AWS
TL;DR: Post-quantum cryptography stopped being a research-paper topic. The reason to care today is “harvest-now, decrypt-later”: an adversary records your encrypted traffic now and decrypts it once a …
How My Setup Learns While You Sleep
TL;DR: The thing that makes an agent get better over time is a loop, and the loop is the same whether you buy it or build it: capture raw interaction, consolidate it on a schedule, and keep the lesson…
Compression Is Intelligence
TL;DR: Information theory says prediction and compression are the same thing measured two ways. That gives the cleanest mental model I know for what a large language model does: it is a compressor of …
