Tools to install

sudo apt update; sudo apt install git

Hyper-V How-Tos

Set up a Static IP for Hyper V guest OS

Motivation: to ssh to the VM without always figuring out what the VM's current IP is.

Windows' default switch dynamically assigns IP address to Hyper V Vms whenever Windows restarts.
To assign a static IP address to a VM, we need to set up an Internal Switch.

Steps:

On a Linux Server machine

curl -O https://raw.githubusercontent.com/angristan/openvpn-install/master/openvpn-install.sh
chmod +x openvpn-install.sh
./openvpn-install.sh

Select add a client, and give it any name you like. A your_client_name.ovpn will be generated in the home folder.

Definition (Code Smells) Code smells are common code anti-patterns which could and should be refactored.

This doc is summarized from Martin Flower's book Refactoring (the 2nd Edition).

Refactoring is all about Change

You may inverse previous refactorings as software grows
You may change names of a function/parameter/varible/... as you learn

How to use this doc

Go to a section of code smell, and the refactoring techniques to that smell are written in Pascal Case under the Solution section. Refer to the book's catalog to get detailed examples and explainations for each refactoring technique.
