in addition to counting dependents you can also run the graph through pagerank to find the most impactful files to convert first. This strategy is useful when converting codebases from JS to TS too because it's common to incorrectly ty

I'm saying that's a different argument, and not one I raised. You incorrectly inferred my meaning from my original post and are now doubling down, I'm not sure why. It's as simple as this: We want to produce as much food

by phpnode 6y ago
I'm talking about the process of turning sunlight into food. If you want to make that process use as few resources as possible (especially fossil fuels) then you need big fields with large machinery. Distribution of wealth is a differe

by phpnode 6y ago
No, I mean it's less efficient. A large field can be farmed with larger machinery which is more fuel, time (and yes, cost) efficient than smaller machinery. There is less time spent moving between fields which can be critical for somet

It's not just that, certain pieces of equipment (combines in particular) are needed at the exact same time in multiple different places, and a delay of a day or even a few hours can be ruinous (if you don't harvest wheat at exactl

Definitely, but smaller fields are a lot less efficient unfortunately.

Wind turbines can be incredibly dangerous, I'd be worried if this was anywhere near my home. jacquesm wrote up his experiences making a wind turbine from scratch here: https://jacquesmattheij.com/how-to-build-a-windmill

A while ago I built this exact mechanism for Flow, it could be done in TypeScript if there was enough demand for it (it's rather a large effort) https://gajus.github.io/flow-runtime/

there's the reflect-metadata package but the type information it exposes is very limited, "object" instead of {a: "foo"} and so on.

I don't think even ReScript can do this (yet?)

yep!

same mechanism, just deal with more edge cases. e.g. whitespace isn't really trimmed correctly at the moment, it doesn't handle escaping quotes in strings and so on. I did think about trying to match postgres's grammar but it

oh let's be clear there's no sensible real world use cases of this thing. it's a demonstration of what TS's type system can do

it's a bit fragile only due to my laziness, it could be done properly if this were a serious project.

> The implementation isn't even that horrible You're making me blush! The list of integers could be replaced by using tuples and reading their lengths to do basic arithmetic. Might run into recursion limits though.

hover over the type annotations to see results in the playground, that's the output :) The errors aren't really errors, just warnings about unused types

I used to be a big fan of the idea of schema.org, but it seems to be used by Google to keep as much traffic as possible on Google properties.

Writing an alternative babel plugin to do the transform this way would be pretty trivial, but doing so for TypeScript is not (officially) possible. TS is going to choose one and it's going to be the one React uses. Also the decision to

It can be done if you write your code like this: function MyThing() { return ( el(A, {value: 123}, [ el(B, {value: 456, foo: true}, [ el(C, {awesome: true}), el(D, {awful: false})

JSX is a tree of deferred function calls. It's nothing to do with HTML, despite them looking similar. Normal function calls are not equivalent

by phpnode 6y ago
This is a missed opportunity to make JSX more than solely about UI and I'm pretty disappointed about it. JSX is really a way to describe a hierarchy of deferred function calls independent of their callers. This could be tremendously us
