Two projects, one mission - hackorum and pginbox join forces
Last week, Zsolt and I jumped on a call with someone who had been building something remarkably similar to what we had been working on, completely independently. That someone is Jack Bonatakis, the creator of pginbox.dev, and that call turned into one of the most energizing conversations we’ve had since launching hackorum.dev.

A New Era of MySQL Monitoring: OpenTelemetry Metrics with Prometheus
In modern application development, observability is no longer optional. It is a core requirement for stable operations, faster troubleshooting, and better understanding of system behavior. Databases are especially important because they often sit at the center of application performance. When a database becomes slow, overloaded, or unavailable, the impact is usually felt across the entire […]

Alkin Tezuysal Director of Services at Altinity Inc. MySQL 9.7 came out on April 21 and I’ve been going through the release notes so you don’t have to. The short version: Oracle has made several previously Enterprise-only features available in the Community Edition, the Hypergraph Optimizer is now free for everyone, and if you’re still on MySQL 8.0, it […]
How I Stopped Babysitting My Coding Agent (With Dotfiles)
Most developers at least try to use coding agents for development-related tasks, but babysitting LLMs and managing their permissions is no fun. Completely skipping permission checks is a dangerous idea on your main machine, and setting up containers or VMs for sandboxing is a pain. Can we do better?
Why Your Application Should Not Use One MySQL User for Everything

On a self-managed server, you worry about two layers: MySQL and the operating system. On OCI MySQL DB Systems with HeatWave, Oracle runs your MySQL instance as a fully-managed service and explicitly […]
