Long-form engineering writing — the economics of AI coding agents, feature flags at scale, HTTP's newest verb, and where the bytes actually go when you compress a file.
Your AI Coding Agent Costs More Than a Junior Dev. Here's the Token Math.
Agentic coding tools burn 10-100x more tokens than chat because the entire context is re-sent on every tool call. A one-word fix can cost 21,000 tokens. Why the meter spins so fast, and five tactics that cut the bill 60-90%.
Your 10GB Zip Is Now 3GB. Where Did the 7GB Go?
The 7GB was never really information — it was repetition and predictability. How zip replaces repeated chunks with pointers, gives common symbols the shortest codes, and why already-compressed data will not shrink.
Feature Flags at Scale: The Good, the Debt, and the Security Hole Nobody Talks About
Feature flags let you deploy code without releasing it and kill a bad feature in seconds. At scale they are indispensable — but every flag is also two code paths, a config surface, and a way for an attacker to switch buggy code back on.
Meet QUERY: The Missing HTTP Method
QUERY is a new HTTP method: the body of a POST with the safety and caching of a GET. It is the verb we have been faking with POST for every search endpoint. What it is and how it looks in code.
