Is telling a model to "not hallucinate" absurd?

Can you tell an LLM "don't hallucinate" and expect it to work? my gut reaction was "oh this is so silly" but upon some reflection, it really isn't. There is actually no reason why it shouldn't work, especially if it was preference-fine-tuned on instructions with "don't hallucinate" in them, and if it a recent commercial model, it likely was.

What does an LLM need in order to follow an instruction? It needs two things:

an ability to perform then task. Something in its parameters/mechanism should be indicative of the task objective, in a way that can be influenced. (In our case, it should "know" when it hallucinates, and/or should be able to change or adapt its behavior to reduce the chance of hallucinations.)
an ability to ground the instruction: the model should be able to associate the requested behavior with its parameters/mechanisms. (In our case, the model should associate "don't hallucinate" with the behavior related to 1).

Webpack with Rails Part 1

I don't like Sprockets, but it's the easiest and best choice for lots of Ruby on Rails projects. When looking for a better way to manage my JavaScript assets and an improved developer story, my current tool of choice is webpack. While I wish Rails supported drop-in asset pipelines the way that Phoenix does, it's not hard to use webpack with Rails.

Migrating a Rails project from MySQL to PostgreSQL

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

Replace mysql2 gem with pg in Gemfile.
Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.

	import { groq } from 'next-sanity' // Replace with another library if you don't use Next.JS

	import { client } from './client' // Replace this with wherever you have set up your client

	/**
	* Resolves all unresolved references when fetching from the Sanity GraphQL API.
	* There is no native way to do this, so we have to do it manually.
	* @param data
	*/
	export const resolveSanityGraphqlReferences = async <T = unknown>(
