The RESTBucks sample project has served as showcase for various Spring related technologies in the context of building a hypermedia based API implementing a high-level business process for almost a decade.

Expressing architectural concepts in code often stops at naming conventions and technologies implicitly describing these concepts. jMolecules provides annotations and types to describe architectural context and technology specific integration to derive co…

I’ve recently been pulled into a discussion about the effect of contracts in distributed systems both technically and regarding team communication.

Recently, I stumbled over a blog post by Jonathan Channon explaining how he got to realize that hypermedia APIs are not some magical thing but rather a pragmatic approach to reduce coupling between services.

Today I devoted my day to a general check in how far Hades can be run with the latest Spring 3 milestone.

As you might not be aware of, besides injecting dependencies into beans Spring is able to inject dependencies into objects that are not instantiated by Spring.

Let me prodly announce version 0.5.0 of Hades.

The latest episode of the JavaPosse podcast presents a session of the this year’s JavaPosse roundup on Scala and application modularity.

Although it took me a while to get used to them, I now pretty much like the annotation based programming model for controllers in Spring MVC.

It’s been a silent release, nevertheless I want to post a tiny shout about it.

The first two days are over, time to wrap up the first half of it.

Passionatedly practicing conference driven development I’d like to announce version 0.4 of the DAO implementation library Hades.
