Follow installation guide from techsviewer.

Before starting the VM first time, need to setup some configuration values not exposed in VirtualBox UI. I used the script below. Run it with the VM's name as input parameter. Example: set-mac-os-high-sierra-vm-data.bat my_vm_name

set-mac-os-high-sierra-vm-data.bat

It is possible!

You can run Docker near natively (without VM) on Windows Subsystem for Linux. It doesn't have all the functionalities but can run Node and Angular server.

Setup

Sounds great. How do I sign up?

Enable Windows Subsystem for Linux

Multiple WSL in a Windows

Use LxRunOffline to install multiple Linux instances on Windows.

# String to number testing
# Converting a string to a int64 number

# This method converts a string's first 10 characters to int64 number. It is a base27 number that

# 1. Convert the string to lowercase
# 2. map a=>1, b=>2, ..., z=>26, and anything else to 0
# 3. if it is not the 10's character, the method multiple its result by 27 and read the next character
