  Vault's TOTP API can validate a six-digit code. That is not yet a complete MFA flow. This Quarkus tutorial adds the missing boundaries: authenticated subject, stored enrollment mapping, strict input validation, a two-minute step-up JWT, normal RBAC, and a replay test against a patched Vault runtime. https://www.the-main-thread.com/p/quarkus-vault-totp-step-up-auth #Java #Quarkus #Vault #TOTP #APISecurity

  AI coding agents make code cheaper. They do not make specification free. I wrote about the spec trap: loose prompts look fast until rework, token burn, human review, and multi-agent drift show up on the ledger. The sweet spot is not a 40-page requirements document. It is validated acceptance criteria, executable tests, and stronger handoff contracts where they pay. https://www.the-main-thread.com/p/spec-trap-agent-work #AI #SoftwareEngineering #Agile

  Java frameworks are usually discussed in terms of benchmarks and best practices. But sometimes, the fastest way to understand a platform is to do something completely ridiculous with it. This article breaks down six and a half intentionally weird Quarkus demos from JChampions Conference. Under the jokes is a serious point: Quarkus is far more flexible than most people realize. https://www.the-main-thread.com/p/six-and-a-half-ridiculous-things-quarkus #Java #Quarkus #JVM #DeveloperExperience...

  🏈 Predicting NFL Games with Java, Quarkus & Tribuo Even if you don't watch sports, the NFL is a perfect dataset for machine-learning pipelines. I show how to pull real ESPN data, engineer features, train a Tribuo model, and serve predictions through a Quarkus microservice. Pure Java. No Python. One clean pipeline from ingestion → training → inference. 👉 https://www.the-main-thread.com/p/nfl-game-prediction-java-quarkus-tribuo-tutorial #Java #Quarkus #MachineLearning #Tribuo #...

  Just published a new deep-dive on building enterprise-grade RAG in Java. In this tutorial, we combine: • Quarkus • Docling (layout-aware PDF parsing) • pgvector + PostgreSQL • Local LLMs via Ollama • And a simple guardrail layer This is the most complete RAG pipeline I’ve built so far, and it’s fully open for you to copy, run, and adapt.

  AI agents behave much more like terminal users than API clients. So it’s not surprising that CLI tools often outperform MCP integrations for many workflows. For Java developers this opens an interesting path: JBang + small CLI tools as agent capabilities. I wrote a deep dive here: https://www.the-main-thread.com/p/ai-agents-cli-tools-jbang-java-architects #Java #AI #DevTools #JBang #AIagents
