You’re Adding AI to the Wrong Layer!

The same discipline that killed raw SQL in route handlers needs to kill scattered AI calls in your domain layer.An engineer on my team asked a reasonable question last month: “Can we write a unit test for this checkout enrichment function?”I hesitated. The function works fine. It’s been used for some time now. It calls the OpenAI API to generate a short product description summary on new items aut...

Scaling Out SignalR: In-Memory State Behind a Load Balancer

A few years ago, I was the architect on a live collaboration tool. Multiple users joined the same session, worked over shared mutable state for hours, and everything traveled through SignalR. The product grew, and we had over 10.000 simultaneous users, and we decided to put more instances behind the load balancer.Then the tickets started. Users inside the same session could not see each other. In ...

My smart-contract scanner reports almost nothing — and that's the whole point

Most Solidity security tools have the same failure mode: they cry wolf. You run them on an audited protocol and get 600 "findings," 98% of which are noise. The signal drowns. Worse — send a client a report full of false positives once, and you've burned your credibility. I've been building a scanner with the opposite goal: report almost nothing, but be right when it does. Zero false positives, ve...

The Framework Tax Is a Product Decision

A few years ago, the default test automation decision was mostly technical. Do we use Selenium? Which language? Where do we run the grid? Today, the menu is much larger. You can write Playwright tests, ask Claude to generate them, use an AI-first testing platform, or combine several of those approaches. That sounds like progress, and it is. But more choices have also made it easier to optimize ...

Stop Paying for the Same Tokens Twice: A Practical Guide to Prompt Caching

You've built a chatbot. Every turn, you re-send the whole conversation — the 8,000-token system prompt, the uploaded PDF, the 15 messages of history — just so the model can answer "and what about Mars?" The model re-reads all of it. Every. Single. Time. You pay full price for all of it. Every. Single. Time. Prompt caching fixes this. It's roughly one extra line of JSON, and it can cut your input c...

I measured what a single Cmd+V costs your AI agent's context window

Short version: I measured what a single paste costs an AI agent. A 2,348-line source file is 40,324 tokens, one fifth of a 200,000 token window, gone in one keystroke. The path to that same file is 19 tokens. Four pastes like that and the agent starts forgetting the instructions you gave it an hour earlier. At the end I show what I did about it.

Artificial intelligence has become an essential part of modern software development. Developers use tools like ChatGPT, Claude, and Gemini to write code, debug applications, generate documentation, and automate repetitive tasks. While AI improves productivity, one important concept is often overlooked: token usage. Understanding tokens isn't just useful for companies building AI products—it's val...
