The One Timeless Benefit of Design Patterns

Actualités, Méthodes et organisation des process IT

There’s not much buzz about design patterns these days. They appear to have joined the hall of fame of accepted wisdom, alongside the Silver Bullet, SOLID and DRY. Lately, I had the opportunity to share some thoughts on the importance of good old design patterns with Koen Aerts, CTO of Team Rockstars IT. Here’s the gist of that talk in a more digestible format.

Before I start, let me set some boundaries, as people can get doctrinaire about definitions. I refer to the good old bridge, builder, decorator, and factory patterns. Architectural patterns like MVC do not fall into the same category, much fewer paradigms like serverless and microservices (aka SOA the next generation).

EclipseCon 2021 Conference Report

Actualités, Méthodes et organisation des process IT

EclipseCon 2021 took place October 25-28. EclipseCon has long been a world-class conference for all things Eclipse. With the Java EE transition to the Eclipse Foundation, EclipseCon has become a truly significant event for Jakarta EE and MicroProfile developers. Due to the pandemic, the 2021 event was virtual (and free!). Jakarta EE unsurprisingly had a strong presence at the conference with talks on Jakarta EE 9.x, Jakarta EE 10, MicroProfile 4.x, MicroProfile 5, Jakarta Security, Jakarta Concurrency, Jakarta REST, Jakarta NoSQL, and MicroProfile GraphQL from speakers such as Tanja Obradovic, Ivar Grimstad, Josh Juneau, Otavio Santana, Emily Jiang, Steve Millidge, Arjan Tijms, Werner Keil, Ed Burns, Rudy De Busscher, and Graham Charters.

I delivered two talks and participated in a panel at the conference focused on Java, Jakarta EE, and Azure. I also helped organize Community Day along with Werner Keil and Petr Aubrecht.

Developing Event-Driven Microservices

Actualités, Méthodes et organisation des process IT

This is the second in a series of blogs on data-driven microservices design mechanisms and transaction patterns with the Oracle converged database. The first blog illustrated how to connect to an Oracle database in Java, JavaScript, Python, .NET, and Go as succinctly as possible. The goal of this second blog is to use that connection to receive and send messages with Oracle AQ (Advanced Queueing) queues and topics and conduct an update and read from the database using all of these same languages.

Advanced Queuing (AQ) is a messaging system that is part of every Oracle database edition and was first released in 2002. AQ sharded queues introduced partitioning in release 12c and is now called Transaction Event Queues (TEQ).
