Working notes
Things I learned building production AI systems, written down before I forget them. Unedited, occasionally wrong, always from a real system.
PHP2Shell: one request takes over PHP
A 10-year-old flaw in PHP itself let one unauthenticated request run code on the server. What happened, who is at risk, and the update that fixes it.
Claude Code just got mods
Change how Claude Code itself works with a few lines of TypeScript. What mods can do, how they differ from hooks and skills, and the risks.
Jev vs Laya: two System One models
A $40M closed API and an open-weights challenger claiming 7.8x, three days apart. What the numbers actually show, and when to pick which.
Claude Opus 5.5 at 40% of Fable's price
Opus 5.5 beat Fable 5.1 on every benchmark Anthropic published, at 40% of Fable's token price. The numbers, the caveats, and what it changes in the stack.
Floci: great at 5 jobs, risky at 4
The free, MIT-licensed AWS emulator that took over when LocalStack put its free edition behind a token - what to use it for, what not to, and the honest caveats.
AEO, GEO, LLMO: what the evidence says
What the studies actually support about being cited by AI search - and what they do not. Click-through data, the one real paper, and the acronyms nobody owns.
The AI Forward Deployed Engineer roadmap
OpenAI, AWS, Anthropic and Google Cloud all moved on FDEs in four months. What the role is, why now, and a six-stage roadmap to it.
AWS AI-DLC threw out the sprint
AI-DLC, AWS's open-sourced AI-driven development lifecycle: three phases, explicit stages, humans validating in real time, and the sprint replaced by the bolt.
One engineer, before lunch
AI-first pods run 25–40% smaller, and top ICs have become one-person departments. Why the individual contributor is winning in 2026.
A second brain around your neck
Neosapien Neo 1: a screen-free AI pendant that turns real conversations into searchable memory and action items. No subscription, made in India.
NVIDIA shrank a supercomputer to 1.2 kg
The DGX Spark: 128 GB of unified memory in a 150 mm box. What the spec sheet says, why the memory bandwidth is the real ceiling, and who should buy one.
