You “can” ask for “water from the tap”, which should be free, but nobody does that and the waiter will probably give you a weird look.

Code first. Use ApprovalTests to catch yourself accidentally breaking the contract/schema. This way you don’t get handcuffed by code generation libraries.

🤔 Curious about Kotlin but worried about rewriting your Java code?
No need – Kotlin and Java work seamlessly in the same Spring project.
Start with a single service and expand from there.

The reason you might want to optimize for non-google search engines is because I think your target audience mostly doesn’t use google as a search engine anymore.
You can search SEO duckduckgo and check the differences with google. Most seo helps all engines.

What immediately comes to mind is seeing a test fail and not understanding from the failure message why it’s failing. E.g. toString() wasn’t implemented and now all I’m getting is reference id’s that are different when I expected to see the properties of a value object being different.

1/ Experiments are useful to learn what's possible, to discover your blind spots, to generate optionality (aka the availability of options even when you don't need them), and to allow innovation. Without experimentation for the sake of discovery, there's no science, art, philosophy.

I was wondering the same thing. When you know it’s a human that wrote it, there’s empathy: “whoever wrote this was under lots of constraints at the time and I’ve been there myself once. I’m happy to fix this code that does something valuable”.
But I can’t apply that when it was vibe coded.
