J-Fall 2021: Jeroen Rosenberg – Cooking your Ravioli “Al Dente” with Hexagonal Architecture

Hexagonal architecture (a.k.a. ports and adapters) is a fancy name for designing your application in a way that the core domain is separated from the outside world by input and output ports.

J-Fall 2021: Maarten Mulders – Dapr: Dinosaur or Developer’s Dream?

Recently, the Dapr community released Dapr into the wild, aiming to simplify cloud-native application development. Dapr lets you abstract your distributed architecture from the underlying infrastructure that powers it. Forget about Kafka, RabbitMQ or any cloud-specific product: you’re talking with a pub/sub broker. Let Dapr take care of how it works. Want to switch later? […]

J-Fall 2021: Nick Tinnemeier – Don’t tell my manager I generate my code – how we autogenerated the dull parts of our REST service.

  I was once told that a good programmer is a lazy programmer. A good programmer avoids typing tedious code, where the code could basically write itself. Self-writing code – wouldn’t that be great? Unfortunately, we’re not quite there yet. In this talk we show you how to be lazy though. We demonstrate how 1) […]

J-Fall 2021: Nicolas Fränkel – A Change-Data-Capture use-case: designing an evergreen cache

When one’s app is challenged with poor performances, it’s easy to set up a cache in front of one’s SQL database. It doesn’t fix the root cause (e.g. bad schema design, bad SQL query, etc.) but it gets the job done. If the app is the only component that writes to the underlying database, it’s […]
