I want to tell you about a problem that took me two years and more than three hundred iterations from scratch and from first principles to solve properly. Not because the problem is hard to describe — it isn't. But because every time I thought I had it, I'd discover a new wall. And the walls kept t

Building a Serverless HTTP 402 Payment Gateway for FastAPI with Solana and Redis

Autonomous AI agents (via AutoGPT, LangChain, MCP, or custom bots) cannot fill out credit card forms or complete 2FA challenges. As agent-to-agent (A2A) economic interactions grow, APIs need a machine-native monetization standard. The x402 protocol leverages standard HTTP error codes combined with

Let Claude Code and Cursor query your database (safely) — the MCP setup

An agent that can read your database answers questions you'd otherwise open a SQL editor for. "Why did signups drop on Tuesday?" "Which orders have been stuck in pending for more than an hour?" "What's actually in the events table?" With a query capability the model answers in seconds; without one i

Spring Boot vs Quarkus on a 512 MB VPS with JDK 25

I ran equivalent Spring Boot 3.5 and Quarkus 3.39 applications side by side on the same 512 MB VPS. Both were JVM applications running on JDK 25. Quarkus native image was not used. Both had the same workload, H2 database, -Xmx80m, Serial GC, and the same JVM tuning. A few results surprised me: Quar

Zero Dependencies, 456 Tests, and One Bug All of Them Missed

The test suite was green. All of it. Every assertion about the QR encoder I'd written passed, the way it had passed for weeks. I held my phone up to the screen anyway, more out of habit than suspicion, and the camera just sat there. No beep, no flash, no redirect. Nothing. A perfectly scannable-look
