Create an Virtual Window Server for Development on AWS

Steps to Create and Connect to a Windows Virtual Machine on AWS

Log on to your AWS Console as an IAM user who has permission to create EC2 instances
Create an EC2 instance and make sure to create KeyPair
- Make sure you check the individual price when selecting the instance type
Open the new EC2 instance and click Connect to view the instruction on how to connect
- Download the RDP file
- Find the Password by decrypting the public key (the pem file from the Create EC2 step)
Download Windows RDP (Remote Desktop)
Create a new connection profile using the RDP file, then connect to the new instance using the decrypted password
After development, stop (not terminate) the instance so you are not being charged for the Compute price.
If you are done with this instance and no longer need it, you can terminate it so that you don’t need to pay for the storage price.

My iOS Dev Log – Set up iOS Dev Environment

I’ve always wanted to learn about iOS dev and 2023 is the year that I am going to tackle it seriously so that I can develop tools for myself and maybe even share them with others for free in the Apple Store. I will start a blog series to chronicle my learning to build my first app.

Here are the first few steps that I need to do to set up my development environment:

Find a Mac (this is easy since we use Mac for work)
Register an Apple Developer membership (to deploy to iOS devices and also to sell in the store)
Install XCode
Verify that I can run the app on my machine (Since I have followed an amazing tutorial to create a FlappyBird using Unity, I used it to verify my iOS dev setup. )
