Ruby: The future of frozen string literals

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

Merge vs. Rebase vs. Squash

I get asked pretty regularly what my opinion is on merge commits vs rebasing vs squashing. I've typed up this response so many times that I've decided to just put it in a gist so I can reference it whenever it comes up again.

I use merge, squash, rebase all situationally. I believe they all have their merits but their usage depends on the context. I think anyone who says any particular strategy is the right answer 100% of the time is wrong, but I think there is considerable acceptable leeway in when you use each. What follows is my personal and professional opinion:

A simple script to clear all the data of your planetscale DB (force-reset from PrismaORM)
// db.ts
import * as schema from "./schema"
export const db = drizzle(connection, { schema })

const tableSchema = db._.schema
if (!tableSchema) {
throw new Error("No table schema found")
