V8

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

SpiderMonkey

SpiderMonkey is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell. It can also be [compiled](https://bytecodealliance.org/articles/making-javascript-run-fast-on

Quick guide to debugging Node.js memory leaks

The basics

Run the app locally using the --inspect switch. For example node --inspect index.js. Note: if you are debugging a complex Next.js app (or similar) you need to use a production build, otherwise you’ll get stuck on "Building dominator tree…" (see this issue for some info). To inspect Oxygen, run yarn build and NODE_ENV=production node --inspect server.js

Open DevTools for Node. You can do this by visiting chrome://inspect/#devices and looking for your app under "Remote Target".

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

This allows you to receive desktop notifications from grunt running inside of a local vagrant box.

How to install

Install `grunt-notify` and add to dev dependencies

This is done on the guest VM (within the vagrant box).
