Kubernetes complexity making your brain run out of RAM? 🤯
Ed Toro's Rails script approach means you don't have to memorize kubectl flags. His patterns create tab-autocomplete paths through K8s configuration, context switching, and pod execution.

We often front-load discovery to feel confident before building—but that's not real agility. Doc Norton explores how continuous learning reduces risk better than perfect plans ever could. https://link.testdouble.com/5b3945

You need to uncover root causes beneath surface-level tech problems. Software problems are human problems.

The number of failed local Docker setups Ed Toro has seen ... 🫣
Ed solves this by treating Rails scripts as "partial function applications," organizing Docker commands so tab-autocomplete guides developers to what they need. Without becoming container experts.

Unlike coding agents, our double agents can quickly distinguish between what’s crap and what’s credible.
Agentic coding makes a lot of things possible, but you still want a human with experience and discernment at the helm.

"We just need to be more careful about quality" … 💥 Famous last words. Developers aren't perfect. Even AI hallucinates and needs human review. So why keep designing systems that assume perfection? You need systems that manage inevitable mistakes. https://link.testdouble.com/1834f3
