macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

Starting Points

How to use this gist

You've got two main options:

Logitech MX Master 3 Extras for Linux With logiops

The Logitech Options program isn't available for Linux, but by a nice guy on GitHub (PixlOne) created an open source project that lets you obtain some of that functionality. It's called logiops. It works in conjunction with the Solaar project as well, which I find especially handy since that shows your available battery life in the system tray and lets you pair/unpair devices with the Logitech Unifying Receiver.

Here are some additional pages with info that I used to generate this documentation:

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

query
mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

	// Note: only for modern browser
	import axios from 'axios'

	// helper function: generate a new file from base64 String
	const dataURLtoFile = (dataurl, filename) => {
	const arr = dataurl.split(',')
	const mime = arr[0].match(/:(.*?);/)[1]
	const bstr = atob(arr[1])
	let n = bstr.length
	const u8arr = new Uint8Array(n)

	const waitFor = (ms) => new Promise(r => setTimeout(r, ms))
	const asyncForEach = async (array, callback) => {
	for (let index = 0; index < array.length; index++) {
	await callback(array[index], index, array)
	}
	}

	const start = async () => {
	await asyncForEach([1, 2, 3], async (num) => {
	await waitFor(50)

	Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

	This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

	usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

	Getting help:
	-h — print basic options
	-h long — print more options
	-h full — print all options (including all format and codec specific options, very long)
