# 151st airhacks tv: floci, BCE vs Hexagonal, Outbound Connectors, Agentic Architecture and Testing

The 2026.10 / 151st edition of airhacks.tv with the following topics:

floci.io live demo: an AWS cloud emulator written in Java with Quarkus and GraalVM
floci vs. LocalStack: smaller, faster, many AWS services implemented in Java
what hexagonal architecture adds to a BCE eBank application
migrating legacy J2EE projects to Quarkus with LLMs works better than expected
are outbound integrations boundaries in a BCE Quarkus application?
zsmith on GitHub and its "concerns" skill from airails.dev
BCE as agentic architecture
better code quality keeps agents fast in complex applications - with bad code you hit the wall earlier than humans do
zagentcapsule (zack): a zero-dependency single executable Java 25 file, about 700 lines, wrapping Apple's container technology on macOS
zjev: a zero-dependency Java SDK for the jev model, soon to be published
jev is a fast, cheap classifier rather than a text generator
time machine to a 2018 gist: the questions have not changed much
web apps without external dependencies: web components are strong with LLMs, because LLMs are trained on standards
JFR for business logging: a Kafka-like experience with business events, in-memory logging and streaming at almost no cost
WebAssembly after eight years: coming and going, it did not overtake JavaScript
agentic testing: a skill generating at most three tests per method with strong assertions instead of assertTrue
assertion coverage that catches mutations, fewer meaningful tests with the same structure are easier to review
skills get shorter as LLMs get more powerful
the JavaOne talk How to write great Java apps with LLMs and agents is online
free BCE online course at BCE: The Screaming Architecture For Humans and LLMs with about 15 lessons and more coming
