Your Quarkus login flow may be exposing more than you think.

I put together a hands-on tutorial for using PAR with Quarkus OIDC and Keycloak, so OAuth request parameters stay out of the browser URL.

Most Java apps have hidden N+1 queries.

You don’t see them. But your DB does.

Hibernate Statistics lets you:
measure queries, detect issues, and enforce performance in tests.

Java + Kubernetes CI the cloud-native way.

This tutorial shows how to build a Tekton pipeline for a Quarkus app that:
• clones code
• builds with Maven
• creates a container with Buildah
• pushes to a Kubernetes registry

Deploying a Java app to Kubernetes usually means writing lots of YAML.

Quarkus takes a different approach.

You write Java. Quarkus generates the Kubernetes manifests and deploys the app.

External APIs are often the weakest part of your tests.

We cover stubs, scenarios, latency simulation, and request verification.

Agents calling your Kubernetes cluster?

Yes.

I built a Kubernetes MCP server with Quarkus + Fabric8, run it on minikube, and expose cluster tools that AI agents can safely call.

Java testing in 2026 looks different.

More teams are replacing slow E2E suites with component tests that run fast and catch failures earlier.

In this article I show how to implement the approach with Quarkus testing tools.

Java framework benchmarks are easy to get wrong.

The new Quarkus benchmark results are interesting — but the real story is the engineering work behind them.

Reproducible environments. Transparent methodology. Real collaboration across the team.

Most Quarkus security tutorials stop at HTTP Basic.

But real apps need more.

• Remember-me sessions
• GitHub OIDC login
• Secure cookies
