pgAgent has been my go to scheduling solution for quite some time. Sadly in 6 months it will be completely retired and the pgAgent UI in pgAdmin will be gone.

The database backend is PostgreSQL, my favorite database Supports Multiple Agents with... Read more ›

This is the writeup, including the parts we didn’t get to live. Live demos keep you honest. On June 10th my AKS workshop went a little sideways. Partway through, Docker Hub rate-limited my image pull and we had to adapt the content on the fly. The original plan was to stand up an AKS cluster with Cilium, an Azure Container Registry with the cluster’s... Read more ›
Recently, I how common polymorphic associations actually are in relational databases — a performance-hostile pattern built around a discriminated foreign key that ORMs (Rails, Django, Hibernate), CRM platforms (Salesforce), and 1C generate automatically.
