Most toxicity filters fail because they treat language as text, not meaning.
In this article I show how to build semantic toxicity detection with Quarkus Guardrails using a dedicated classifier model, not regex or vague embeddings.
Multi-dimensional scoring. In-process ONNX. Production-grade Java.

Why do 48 hours sometimes equal 47?
Because time in Java is not arithmetic — it’s policy.
This deep dive shows how DST silently breaks billing logic, why Joda-Time modeled time correctly, and how to migrate legacy code safely to java.time using a real Quarkus example.

Enterprise Java has matured into one of the most stable and widely adopted ecosystems in software development. Yet for many teams, the biggest challenges no longer come from the language itself, but from the complexity of the environments built around it. Modern enterprise Java teams are dealing with a mix of legacy Java EE applications,…...

mTLS looks simple until you realize what it doesn’t protect you from.
A trusted client certificate is not the same thing as an allowed client.
If your Java service stops at “the handshake worked,” you’re leaving a gap attackers can walk through.
I wrote up a hands-on Quarkus implementation that shows:
– where TLS ends
– where security should begin
– and how to enforce certificate rules before business logic runs

Most AI coding tools work best on small, isolated changes.
That breaks down fast in real Java systems.
I’ve been working with IBM Bob on long-lived codebases and wrote down what it actually does well: planning before coding, system-level analysis, and controlled modernization.
Neutral, technical, and based on real use.
