Linux Desktop on Apple Silicon in Practice

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

  • Two native ports exist.
import React from "react";
export type ColorScheme = "light" | "dark";
export default function useColorSchemePreference(
defaultColorScheme: ColorScheme = "light"
) {
let darkQuery = "(prefers-color-scheme: dark)";
let [colorScheme, setColorScheme] = React.useState<ColorScheme>(
typeof window === "object" && window.matchMedia

Everything I Know About UI Routing

Definitions

  1. Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
    1. pathname - The "file/directory" portion of the URL, like invoices/123
    2. search - The stuff after ? in a URL like /assignments?showGrades=1.
    3. query - A parsed version of search, usually an object but not a standard browser feature.
    4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
    5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

better createContext APIs with setters, and no default values, in Typescript. this is documented in https://github.com/typescript-cheatsheets/react-typescript-cheatsheet/blob/master/README.md#context
// create context with no upfront defaultValue
// without having to do undefined check all the time
function createCtx<A>() {
const ctx = React.createContext<A | undefined>(undefined)
function useCtx() {
const c = React.useContext(ctx)
if (!c) throw new Error("useCtx must be inside a Provider with a value")
return c
}
return [useCtx, ctx.Provider] as const

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

import React, { Component, createContext } from 'react'
function initStore(store) {
const Context = createContext();
class Provider extends React.Component {
constructor() {
super();
this.state = store.initialState;
}
