What a fantastic end to the day today!

Oh man, this is such a disaster.

Pretty intuitive animation explaining seasons, equinox, solstice, length of day and night.

Today marks the autumn equinox in the Northern Hemisphere.

Ansible vs Terraform

Terraform
- Build Infrastructure
- Creates servers, databases, networks
- Provisions cloud resources
- Example: Create 3 EC2 instances + load balancer

Ansible
- Configure Software
- Installs packages and apps
- Configures services
- Example: Install Nginx, deploy app, start services

Key Differences

Terraform
- Manages infrastructure (cloud resources)
- Declarative (describe end state)
- Tracks state in file
- Best for: AWS, Azure, GCP setup

Ansible
- Manages configuration (software)
- Procedural (list of tasks)
- No state tracking
- Best for: Installing, configuring, deploying

Real Workflow

Step 1: Terraform
- Create 3 servers
- Setup VPC and security groups
- Create RDS database

Step 2: Ansible
- Install Docker on all servers
- Copy app configs
- Deploy application
- Restart services

Simple Analogy
Terraform - Build the house
Ansible - Furnish and decorate it

Use Terraform for:
- Creating cloud infrastructure
- Managing AWS/Azure resources
- Networking setup

Use Ansible for:
- Installing software
- Deploying applications
- Managing configurations

Every second, the Sun ejects 1.5 million tons of material into space at hundreds of miles per second, but Earth's magnetic field protects it from the solar wind.

Short explanation of the physics Nobel Prize 2025

In classical mechanics you can know where a particle is and its momentum at the same time. In Quantum mechanics you can't. All information is in the wavefunction. Even if a particle is trapped, part of the wavefunction..

[The Nobel Prize @NobelPrize]

When you throw a ball at a wall, you can be sure it will bounce back at you.

You would be extremely surprised if the ball suddenly appeared on the other side of the wall. In quantum mechanics this type of phenomenon is called tunnelling and is exactly the type of phenomenon that has given it a reputation for being bizarre and unintuitive.

The 2025 #NobelPrize laureates in physics John Clarke, Michel H. Devoret and John M. Martinis, used a series of experiments to demonstrate that the bizarre properties of the quantum world can be made concrete in a system big enough to be held in the hand. Their superconducting electrical system could tunnel from one state to another, as if it were passing straight through a wall. They also showed that the system absorbed and emitted energy in doses of specific sizes, just as predicted by quantum mechanics.

Stop collecting AWS certifications thinking that’s how you learn cloud.

If you are just starting to learn AWS, here are 7 beginner-friendly AWS projects that will teach you more than any shiny certification will.

And you can do it on your own:

Project 1: Static Website on S3
Host a simple site for $0/month plus learn bucket policies, CloudFront integration, and why public buckets are dangerous.

Project 2: EC2 Web Server
Launch an instance and deploy a small app while discovering security groups, SSH keys, and why you need load balancers.

Project 3: File Backup System
Upload and retrieve files in S3 while understanding storage classes, lifecycle policies, and versioning.

Project 4: Simple Database App
Use RDS with a Python/Flask app to learn connection pooling, backup strategies, and why you don’t run databases on EC2.

Project 5: CloudFront Distribution
Speed up your static site with a CDN while learning edge locations, cache invalidation, and origin behaviors.

Project 6: Serverless Function (Lambda)
Trigger a Python function when files are uploaded and discover cold starts, memory limits, and event-driven architecture.

Project 7: Route 53 Domain Setup
Buy a domain and connect it to S3/EC2 while learning DNS records, health checks, and traffic routing.

Each project teaches you one core AWS concept through real implementation, not theory.

You don’t need to learn all 100+ AWS services, you just need 10:
VPC, EC2, RDS, ECS, Lambda, IAM, S3, EKS, Route53, Secrets Manager/KMS

Master these through building, and the rest will make sense when you need them.
