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:

  1. Find a Mac (this is easy since we use Mac for work)
  2. Register an Apple Developer membership (to deploy to iOS devices and also to sell in the store)
  3. Install XCode
  4. 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. )

Create a New AWS Account

You can create an AWS account for free, as long as you provide an email address and a credit card. For the first year, you can use the 12-month Free Tier offering in your first 12 month of account creation. Not all AWS resources are Free Tier eligible, so make sure before creating any AWS resources.

To create an AWS account, simply go to https://aws.amazon.com and click on “Create an AWS Account”.

The account creation process will ask you for your email address, address, as well as a valid credit card. After email verification, you can then log in to your new AWS account.

AI 2023- ChatGPT

What is ChatGPT

ChatGPT is a trained model which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer follow-up questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests.

This ChatGPT model was trained using RLHF (Reinforcement Learning from Human Feedback).

The initial model was trained using supervised fine-tuning. A human AI trainer would play both parts: user and AI assistant. (for more details, read the ChatGPT blog from OpenAI)
