What is Docker ? 1 • Development Lets say You created an Application And that's working fine in your machine 2 • Production But in Production it doesn't work properly Developers experince it a lot 3 • That is when the Developer's famous words are spoken Client - Your application is not working 😡 Developer - It's working on my Machine 😒 4 • The Reason could be due to: • Dependencies • Libraries and versions • Framework • OS Level features • Microservices That the developers machine has but not there in the production environment 5 • DOCKER We need a standardized way to package the application with its dependencies and deploy it on any environment. Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. So it will always work the same regardless of its environment 6 • How Does Docker Work? Docker packages an application and all its dependencies in a virtual container that can run on any Linux server. 7 • Each container runs as an isolated process in the user space and take up less space than regular VMs due to their layered architecture.

Getting started with SQL comparison operators. If you're new to SQL, understanding comparison operators is one of the first things you'll need to learn. They’re really important for filtering and analyzing your data. Let’s break them down with some simple examples. Comparison operators let you compare values in SQL queries. Here are the basics: 1. = (Equal To): Checks if two values are the same. Example: SELECT * FROM Employees WHERE Age = 30; (This will find all employees who are exactly 30 years old). 2. <> or != (Not Equal To): Checks if two values are different. Example: SELECT * FROM Employees WHERE Age <> 30; (This will find all employees who are not 30 years old). 3. > (Greater Than): Checks if a value is larger. Example: SELECT * FROM Employees WHERE Salary > 50000; (This will list all employees earning more than 50,000). 4. < (Less Than): Checks if a value is smaller. Example: SELECT * FROM Employees WHERE Salary < 50000; (This will show all employees earning less than 50,000). 5. >= (Greater Than or Equal To): Checks if a value is larger or equal. Example: SELECT * FROM Employees WHERE Age >= 25; (This will find all employees who are 25 years old or older). 6. <= (Less Than or Equal To): Checks if a value is smaller or equal. Example: SELECT * FROM Employees WHERE Age <= 30; (This will find all employees who are 30 years old or younger). These simple operators can help you get more accurate results in your SQL queries. Keep practicing and you’ll be great at SQL in no time. Like this post if you need more 👍❤️ Hope it helps :)

If you're a software engineer in your 20s, beware of this habit, it can kill your growth faster than anything else. ► Fake learning. It feels productive, but it's not. Let me give you a great example: You wake up fired up. Open YouTube, start a system design video. An hour goes by. You nod, you get it (or so you think). You switch to a course on Spring Boot. Build a to-do app. Then read a blog on Kafka. Scroll through a thread on Redis. By evening, you feel like you’ve had a productive day. But two weeks later? You can’t recall a single implementation detail. You haven’t written a line of code around those topics. You just consumed, but never applied. That’s fake learning. It’s learning without doing. It gives you the illusion of growth, while keeping you stuck. 📌 Here’s how to fix it: Watch fewer tutorials. Build more things. Learn with a goal: “I’ll use this to build X.” After every video, write your own summary. Recode it from scratch. Start documenting what you really understood vs. what felt easy. Real growth happens when you struggle. When you break things. When you debug. Passive learning is comfortable. But discomfort is where the actual skills are built. Your 20s are for laying that solid technical foundation. Don’t waste them just “watching smart.” Build. Ship. Reflect. That’s how you grow.
