You type a domain name, but your network only speaks IP addresses.
Here is the exact DNS resolution hierarchy:

What is one task you would trust an AI Agent to handle for you?

New AI Basics Short is live.

Chatbot vs AI Agent is one of the most common areas of confusion right now, so I broke it down without the jargon.

What would you rather delegate to an AI Agent instead of handling through a chatbot?

Chatbots and AI Agents are often spoken about like they are the same thing — but there is an important difference.

In this short video, I break it down using one simple mental model:

#AIAgent #Chatbot #AIAgents #ArtificialIntelligence #AIBasics

Quick mental model:

Authentication → Who are you? Authorization → What can you do? OIDC → Identity OAuth 2.0 → Delegated access JWT → Token format

Which distinction would you explain differently in a system-design interview?

#Authentication #Authorization #OAuth2

New visual tech breakdown:

Authentication vs Authorization — with OAuth 2.0, OIDC and JWT

Watch/read it on K THE TECHMAN (https://t.co/XMwMEpo6B8).

#Authentication #Authorization #OAuth2 #OIDC #JWT

[Khadir @Khadir0909]

One distinction worth remembering:
ID Token → tells the client about the authenticated user.
Access Token → is presented to a protected resource/API.

What causes more confusion in your experience: OAuth vs OIDC, or ID Token vs Access Token?

#Authentication #Authorization

Authentication, Authorization, OAuth, OIDC and JWT are often discussed together — but they solve different problems.

Predict → Compare → Adjust → Repeat.

New AI Basics Short 👇
How does AI actually learn?

I’ve broken it down using one simple loop:
Predict → Compare → Adjust → Repeat.

Hope this makes the training process much easier to picture.

What fools people more: AI sounding confident, or AI giving an answer that looks factual? 👇

New AI Basics reel 👇

This one explains how AI is actually trained using one simple loop:
Predict → Compare → Adjust → Repeat.

Would love to know if this makes AI training easier to understand.

What does your production environment use today — VMs, containers, or containers running inside VMs? And what drove that choice? 👇

VM vs Container: You’re Comparing the Wrong Layers

A simple visual breakdown of how VMs and containers actually differ —
VM → isolate the MACHINE
Container → isolate the APPLICATION

VM vs Container — explained visually and without the usual oversimplification.

If you work with cloud, DevOps, containers, or system design, this one is worth saving.
VM → isolate the machine
Container → isolate the application
