Fixing VirtualBox Error in latest Mac OS

Usually the issue is fixed on uninstalling the VirtualBox and reinstalling it as it re-authorizes to load kernel modules

The way I resolved - Update(6.1.10) to a newer version of VB (6.1.16)

Update to recent Version of VBox using link below

https://download.virtualbox.org/virtualbox/6.1.16/VirtualBox-6.1.16-140961-OSX.dmg

Once finished download and installation

Configuring the static IP for virtual box with internet access

What we are currently using is the Bridged network and that works great out of the box but if we are using laptop which are always connecting on different network which results into IP always changing can make working with VM a little troublesome as you would need to change the config in hosts file with every IP change.

Another approach is to use two adapter instead one(bridged) to make VM connection - NAT and Host only Adapter.

One helps us keep a static IP address for the VBox and other gets us internet access.

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

	(force) clear you npm cache
	`sudo npm cache clean -f `

	install n (this might take a while)
	`sudo npm install -g n `

	upgrade to the current stable version
	`sudo n stable `


	cd /var/www/my_website_serving_dir

	sudo chown -R $USER:www-data .

	sudo find . -type f -exec chmod 664 {} \;
	sudo find . -type d -exec chmod 775 {} \;

	sudo chgrp -R www-data storage bootstrap/cache
	sudo chmod -R ug+rwx storage bootstrap/cache


	function car(make,mileage){

	this.make = make;
	this.mileage = mileage;

	}


	car.prototype.incrementMileage = function(){

	// map
	const map = (arr, func) => {

	const outputArr = [];

	for (let i = 0; i<arr.length; i++ ){
	outputArr.push(func(arr[i]));
	}
	return outputArr;
	}

	# to generate your dhparam.pem file, run in the terminal
	openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

	font-size: calc(25px + (26 - 14) * ((100vw - 300px) / (1600 - 300)));
	line-height: calc(1.3em + (1.5 - 1.2) * ((100vw - 300px)/(1600 - 300)));
