  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’ve been tracking workouts on Strava for years. At some point, I wanted the data outside the app. This article shows how to: • ingest GPX from Apple Health / Strava • store routes properly with PostGIS • extract heart rate data • render maps and server-side images • all in a Quarkus-based Java backend No dashboards. No vendor lock-in. Just data you own. https://www.the-main-thread.com/p/java-quarkus-apple-health-gpx-postgis #Java #Quarkus #PostGIS #GPX #SelfHosted #OpenData

  Validation logic drifting between frontend, backend, and batch jobs is a real production problem. This article shows how to move validation into your Protobuf schema using Protovalidate, and enforce the same rules in Quarkus, JavaScript, Python, and more. Schema as contract. Validation as infrastructure. 👉 https://www.the-main-thread.com/p/protobuf-protovalidate-quarkus-schema-validation #Java #Quarkus #Protobuf #APIDesign #SchemaFirst #BackendEngineering #FOSS

  Random thought while cleaning the house: where’s AI when you really need it.

  I integrated a native image generation model directly into a Java application using Quarkus and the Java FFM API. No Python stack, no sidecars, no external services. Just in-process inference, explicit memory ownership, and predictable behavior — even on Apple Silicon.

  Flyway migrations are not just SQL scripts. They’re startup code — and startup code can fail your system. This article shows how to use Flyway callbacks in Quarkus to: • block unsafe migrations • validate production state • measure migration time • fail fast before your app becomes ready No magic. No demos. Real startup behavior. 🔗 https://www.the-main-thread.com/p/flyway-callbacks-quarkus-production-migrations #Java #Quarkus #Flyway #Database #DevOps #Production

  RFC 9457 fixes API error responses. Quarkus makes it practical. This article shows how to: • standardize API errors with Problem Details • expose them cleanly in Swagger UI • document business errors via stable type URIs • avoid annotating every endpoint by hand If you care about API contracts and developer experience, this is worth a read. https://www.the-main-thread.com/p/rfc-9457-quarkus-api-error-handling-swagger #Java #Quarkus #APIs #OpenAPI #RFC9457 #DeveloperExperience

  I built a full WebDAV server with Quarkus + Vert.x. Not a toy. Not a demo. Something you can actually mount in macOS Finder. This article walks through: – Handler-based WebDAV architecture – PROPFIND, PUT, MKCOL, LOCK, DELETE – Vert.x file I/O without blocking – Why Finder breaks when LOCK is missing If you ever wondered how WebDAV really works under the hood, this is for you. https://www.the-main-thread.com/p/webdav-server-java-quarkus-vertx #Java #Quarkus #Vertx #WebDAV #BackendEngineering...

  This is a hands-on walkthrough of building a real-time dashboard with Quarkus + Redis TimeSeries. Live ingestion via WebSockets, automatic downsampling, multi-resolution queries, and a simple browser UI. Crypto is just the data source.
