Also the more attentive reader of the pair of […]

How to explain backend changes that support undelivered features

My current work environment is in a cost-pressured large national transport enterprise with a familiar internationally-recognised brand name. We have to build a lot of systems that model many real-world, highly-regulated, parameters and states.

“Jobs’ genius is that he builds these products that people really like to use because he has taste and can build things that people really find compelling. Ritchie built things that technologists were able to use to build core infrastructure that people don’t necessarily see much anymore, but they use everyday.” via Dennis Ritchie: The […]

Spring, JPA/JTA, and multiple persistence units, with view transactions

I have grappled with this topic before. Tonight, after 13 hours of struggle, I finally got my web app perfected in this regard. It all started when I needed to start the Transaction out in the view, i.e. as soon as the resource is opened on the HTTP side (rather than when the database service […]
