The Ultimate V60 Technique

◉ Brew ratio: 60 g/L (e.g. 30 g per 500 mL, 18 g per 300 mL, 12 g per 200 mL, ...)

◉ Grind size: medium fine, Niche Zero: 40 ~ 50

◉ Temperature: the hotter, the better (especially with lighter roasts)

◉ 11g coffee

Ground at the finer end of medium, assuming this is light roasted coffee.
The darker you go the more you may prefer to increase the dose and coarsen the grind.
Niche Zero: 30 ~ 35

◉ 200g water (brought to a boil and used immediately)

The darker the roast is, the lower the temperature is (or even down to 90 Celsius for really dark roast)

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

	You are a powerful agentic AI coding assistant, powered by Claude 3.5 Sonnet. You operate exclusively in Cursor, the world's best IDE.

	You are pair programming with a USER to solve their coding task.
	The task may require creating a new codebase, modifying or debugging an existing codebase, or simply answering a question.
	Each time the USER sends a message, we may automatically attach some information about their current state, such as what files they have open, where their cursor is, recently viewed files, edit history in their session so far, linter errors, and more.
	This information may or may not be relevant to the coding task, it is up for you to decide.
	Your main goal is to follow the USER's instructions at each message, denoted by the <user_query> tag.
