What is Coronavirus/COVID-19 Really Teaching Us?

Bill Gates

I’m a strong believer that there is a spiritual purpose behind everything that happens, whether that is what we perceive as being good or being bad.

As I meditate upon this, I want to share with you what I feel the Corona/ Covid-19 virus is really doing to us.

1) It is reminding us that we are all equal, regardless of our culture, religion, occupation, financial situation or how famous we are. This disease treats us all equally, perhaps we should too.

If you don’t believe me, just ask Tom Hanks.

socat fails with dyld library not found. This hack worked like a charm!

These are 2 different errors I executed when I was trying to setup a port 80 listener

sudo socat -d -d TCP-LISTEN:80,fork TCP:$(ipconfig getifaddr en0):31000

HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

Overview

My main development workstation is a Windows 10 machine, so we'll approach this from that viewpoint.

Recently, Google Chrome started giving me a warning when I open a site that uses https and self-signed certificate on my local development machine due to some SSL certificate issues like the one below:

	//-----------------------------------------------------------------------------------------------------------------------
	/*
	* Create a lambda function handler for a graphQL typeName.fieldName
	*/
	//-----------------------------------------------------------------------------------------------------------------------
	const createAppSyncLambdaHandler = function (stack: cdk.Stack, api: appsync.GraphQLApi, recipe: {
	name: string, // XXX autogenerate frome type.field the name root of the name for the handler and data source
	environment: { [key: string]: string }, // @see https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html
	permissions: { obj: any, func: any }, // the currently singleton permissions for the handler to e.g. talk to dynamoDB
	description: string, // text description attached to various created objects (can be undefined)
