Has AI Finally Solved the Navier–Stokes Millennium Problem? 🤯

For decades, the Navier–Stokes Problem has been one of mathematics' greatest unsolved mysteries, carrying a $1,000,000 prize for a correct solution.

Now, OpenAI has announced that an advanced AI system may have discovered a proof, potentially solving a problem that has challenged mathematicians for nearly 200 years.

But there's a catch: the mathematical community is still reviewing the result, and the debate is far from over.

Could this be the moment AI enters the history books of mathematics?

Vim is a modal text editor that lets you perform complex editing tasks without constantly moving your hands between the keyboard and mouse.

Once you understand its core concepts, navigating files, editing code, searching, replacing text, and managing multiple files becomes incredibly fast.

✅ Vim Modes (Normal, Insert, Visual)
✅ Essential Navigation Commands
✅ Editing & Search Commands
✅ Copy, Paste & Delete Operations
✅ Splits, Buffers & Tabs
✅ Macros & Registers
✅ Undo Tree & Productivity Tips
✅ .vimrc Configuration Basics

Whether you're a Python developer, Linux user, DevOps engineer, Backend developer, or System Administrator, learning Vim can significantly improve your terminal productivity.
The learning curve may feel steep at first, but the long-term payoff is worth it.
Question: Have you ever tried Vim? What was the most confusing thing when you started?

Today, I’m going to explain Continuous Integration (CI) and Continuous Deployment (CD) in a way that actually makes sense—not just by memorizing commands, but by understanding why we need them and what is happening behind the scenes.

We know that when something happens in our project—for example, when we push code to GitHub—we need certain things to happen automatically.

We need to:
→ Install dependencies
→ Run tests
→ Check whether the code is working
→ Build the application
→ And, if everything is successful, deploy it 🚀

But the real question is:

How do we make all of this happen automatically?

That’s where GitHub Actions comes in.

In this complete guide, I’ll break down the whole process step by step—from workflow, events, jobs, steps, actions, and runners to a real-world CI/CD pipeline.

The goal is not just to know what GitHub Actions is.

The goal is to understand:

“When this happens → we need this → then this happens → and finally our application gets deployed.”

Once you understand this flow, CI/CD becomes much easier to understand.

So, let’s break it down from the beginning. 🚀

# PostgreSQL (psql) Terminal Guide

Here I have explained almost everything I learned while connecting to PostgreSQL through the terminal using **psql**. This guide covers different connection methods, how authentication works, what Peer Authentication actually means, how to inspect databases and tables, and how to troubleshoot common connection errors.

My goal with this infographic is to provide a quick reference that helps beginners understand what is happening behind the scenes when they connect to PostgreSQL from the terminal and work with databases in real projects.

Note: All examples are based on PostgreSQL running locally on Linux and are intended for learning, practice, and backend development workflows.
