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.

How to use this gist

You've got two main options:

Moving gulpfile from CommonJS (CJS) to ECMAScript Modules (ESM)

Context

del v7.0.0 moved to pure ESM (no dual support), which forced me to move my gulpfile to ESM to be able to continue to use del.

The author sindresorhus maintains a lot of npm packages and does not want to provides an upgrade guide for each package so he provided a generic guide. But this guide is a bit vague because it's generic and not helping for gulp, hence this guide.

Guide

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

Demystifying Docker Volumes for Mac and PC Users

Docker runs on a Linux kernel

Docker can be confusing to PC and Windows users because many tutorials on that topic assume you're using a Linux machine.

As a Linux user, you learn that Volumes are stored in a part of the host filesystem managed by Docker, and that is /var/lib/docker/volumes. When you're running Docker on a Windows or Mac OS machine, you will read the same documentation and instructions but feel frustrated as that path don't exist on your system. This simple note is my answer to that.

When you use Docker on a Windows PC, you're typically doing one of these two things:

Run Linux containers in a full Linux VM (what Docker typically does today)

	export USER=""
	export REPO=""
	export BRANCH="master"
