Using TypeScript Node.js with native ESM

This reference guide shows how to configure a TypeScript Node.js project to work and compile to to native ESM.

Rationale

CommonJS module system was introduced by the Node.js developers due to the lack of the notion of "modules" in the original JavaScript (ECMAScript) language specification at that time. However, nowadays, ECMAScript has a standard module system called ESM — ECMAScript Modules, which is a part of the accepted standard. This way CommonJS could be considered vendor-specific and obsolete/legacy. Hopefully, TypeScript ecosystem now supports the "new" standard.

So the key benefits are:

Podman with docker-compose on MacOS.

Podman an alternative to Docker Desktop on MacOS

Getting podman installed and started is super easy.
Just use brew to install it.

> brew install podman

Now since podman uses a VM just like the Docker Client on MacOS we need to initialize that and start it.

Yo dawg, I heard you like port-fowards so I'm going to port-forward your port-forward.

Say you want to test something like maybe run something in minikube locally but connect to something running in the kube cluster.

Do your kube port foward

kubectl --context k8s-uw1-gcp port-forward prometheus-prometheus-server-7b6f9d99f8-m4vt6 9090

WannaCry|WannaDecrypt0r NSA-Cyberweapon-Powered Ransomware Worm

Virus Name: WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY
Vector: All Windows versions before Windows 10 are vulnerable if not patched for MS-17-010. It uses EternalBlue MS17-010 to propagate.
Ransom: between $300 to $600. There is code to 'rm' (delete) files in the virus. Seems to reset if the virus crashes.
Backdooring: The worm loops through every RDP session on a system to run the ransomware as that user. It also installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (source: malwarebytes)
Kill switch: If the website www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com is up the virus exits instead of infecting the host. (source: malwarebytes). This domain has been sinkholed, stopping the spread of the worm. Will not work if proxied (source).
