I CAN’T BELIEVE THE GOAT JUST REPLIED TO ME.
@marclou has been a huge inspiration for me and so many builders.
36 startups. $3M earned. 400K followers.
Keep building. Keep posting. Keep growing.
This genuinely made my day. ❤️

₹12.7k.(134 USD)
That was my first X payout.
It took almost 3 months including 5 payouts below the minimum threshold.
But when that ₹12.7k finally hit my bank account, I didn't think about the money.
I thought about my father.
He used to do heavy labour work for ₹10k–₹12k a month.
For someone else, ₹12.7k might be a small payout.
For me, it felt like a glimpse of the life I want to give my father.
So if you're at 500 or 1,000 followers today, don't quit.
Give yourself 3–4 months.
Post consistently. Engage genuinely. Build your audience.
You don't need to go viral. You just need to keep showing up.

Backend Interview:
Your API gets 10,000 requests/minute.
Every request runs the same expensive database query.
The data changes only once every 5 minutes.
Database CPU hits 90%.
You can't upgrade the database.
What would you change?

I’m NOT looking for:
→ Growth gurus
→ Networking experts
→ Personal branding bros
→ LinkedIn celebrities
I want internet friends who build weird stuff, disappear into the mountains, and come back with crazy ideas.
If that’s you, let’s adventure.
I AM NOT looking to connect with the following:
• Growth hackers
• SaaS experts
• LinkedIn gurus
• People who "love networking"
I want internet friends who build weird stuff then disappear into the mountains.

Backend Interview:
1,000 API requests.
Each takes 500ms.
Sequentially:
1,000 × 500ms = 500 seconds
≈ 8.3 minutes
But the requests are independent.
Same requests.
Same responses.
One change makes it 10× faster.
What’s the fix?

4 months ago, I barely knew what SaaS meant.
Today, I’m about to hit 4,000 followers, crossed 10M+ views, and made my first $134 from the internet.
Here’s what happened:
On May 17, I started posting seriously on X after getting Premium.
Before that, I was mostly active on LinkedIn.
Honestly, I didn’t know much about X.
I had around 100+ followers and absolutely no idea about:
→ SaaS
→ MRR / ARR
→ Indie hackers
→ Indie developers
→ Building in public
I just started posting.
Then I kept posting.
I kept engaging.
I kept learning from people building real things.
Four months later:
→ ~4,000 followers
→ 10M+ views
→ Monetized on X
→ $134 received from X
→ First time earning dollars from the internet
That first $134 hit differently.
It wasn't just money.
It was proof that something I started from almost zero could actually create value on the internet.
And X taught me much more than how to grow an account.
I discovered SaaS.
I learned how people build and launch products.
I found founders and developers sharing their journeys openly.
I watched people go from 0 → 10K+ followers while building real businesses.
That's what makes X special to me.
You don't need to be an expert before you start.
You can start with 100 followers, share what you're learning, meet people, improve every day, and see where it takes you.
Four months ago, I had no idea what SaaS, MRR or ARR even meant.
Today, I'm almost at 4,000 followers.
I'm genuinely glad I started posting.
Just keep showing up.

Hi everyone,
I’m a BTech’28, 3rd-year student.
I have done 1200+ DSA problems.
And honestly, I’m tired.
Every day there’s another buzzword:
Full Stack.
AI.
ML.
Deep Learning.
Backend.
System Design.
DevOps.
And so on…
At some point, you start feeling like you’re supposed to learn EVERYTHING.
I’ve already done a lot:
→ 1200+ DSA problems
→ Next.js + MERN / Full Stack
→ OS
→ OOP
→ DBMS
→ CN
I started my DSA journey from the first semester of my BTech in 2024 with one simple goal:
Get a good job. Aim: 15 LPA+.
I posted about my journey too.
Then I went silent.
Instead of posting, I kept working.
In roughly last month, I completed the revision of:
Trees → BST → AVL → Heaps → Graphs → BFS → DFS → Graph Algorithms → Greedy → Backtracking → N-Queens → Sudoku and more.
Now it’s September 10, 2026.
And I’ve made a decision.
I’m done chasing everything.
For now, I’m going ALL IN ON DSA.
DSA.
DSA.
DSA.
I don’t know what will happen.
Maybe this takes me somewhere really good.
Maybe it doesn’t.
But one thing I know:
I’m going to work so hard that even if the exact result I want doesn’t come, something good will come out of this effort.
Because I genuinely believe:
Input = Hard Work
Output = Something Good.
Hard work never goes to waste.
Let’s see where this takes me. 🫡

What if your AI could use your tools, files, databases and APIs?
That’s what MCP (Model Context Protocol) is designed to solve.
Without MCP:
AI → Custom integration → Tool
AI → Custom integration → Database
AI → Custom integration → API
With MCP:
AI → MCP → Tools / Data / APIs
An MCP server can expose:
→ Tools — actions the AI can call
→ Resources — data the AI can read
→ Prompts — reusable instructions/workflows
Example:
You ask an AI:
“Find our top customers and create a report.”
The AI can:
→ Query your database
→ Analyze the results
→ Create the report
→ Return it to you
The important part:
MCP doesn’t make AI smarter.
It gives AI a standard way to interact with the external systems it needs.
Think of MCP as a common interface between AI and the tools it needs to get work done.
That’s why MCP matters for AI agents.
Save this if you’re learning AI agents.
And comment below:
What’s the first tool you’d connect to an AI agent using MCP?

Props vs State in React.js
One of the most important concepts to understand in React:
Props → Data coming IN
State → Data managed INSIDE
Props:-
Props are used to pass data from a parent component to a child component.
function User({ name }) {
return <h2>Hello, {name}</h2>;
}
<User name="Ash" />
Think of props as function arguments.
→ Passed from parent → child
→ Read-only
→ Used to make components reusable
State:-
State is data that a component manages itself.
const [count, setCount] = useState(0);
<button onClick={() => setCount(count + 1)}>
{count}
</button>
→ Can change over time
→ Updating state re-renders the component
→ Used for interactive UI
Simple analogy
Props = Gift 🎁
Someone gives you something.
State = Your wallet 👛
You control what’s inside and can change it.
Remember:
Props → Parent gives data
State → Component manages data
If you understand this difference, React becomes MUCH easier.
Save this for later.

If HTML, CSS and JavaScript can build websites,
why do we need React?
HTML → Structure
CSS → Styling
JavaScript → Logic + Interactions
For small websites, that's enough.
But as the application grows, managing everything with vanilla JavaScript becomes harder:
→ Lots of DOM manipulation
→ Difficult state management
→ Repetitive UI code
→ Harder code maintenance
→ Less reusable components
→ Complex UI updates
This is where React.js helps.
React lets you build your UI using reusable components.
Instead of thinking:
"Find this element → change its content → update another element → manage the state"
You think:
"Here is my state → render the UI based on that state."
React gives you:
→ Components for reusable UI
→ State for managing changing data
→ Declarative UI for predictable rendering
→ Efficient updates to the UI
→ A large ecosystem for building complex apps
Example:
HTML + CSS + JS
↓
Build and manage the UI manually
React
↓
Break UI into components
↓
Manage state
↓
React handles UI updates
Important:
React does NOT replace HTML, CSS or JavaScript.
React is built on top of them and provides a better way to structure and manage complex user interfaces.
Learn HTML, CSS and JavaScript first.
Then React will actually make sense.

JWT Tokens in 60 seconds 🔐
JWT = JSON Web Token
It’s commonly used to authenticate users without storing a session on the server.
Simple flow:
User → Login → Server verifies credentials → Server creates JWT → Client stores token → Client sends token with future requests → Server verifies JWT → Access granted ✅
JWT has 3 parts:
→ Header
→ Payload
→ Signature
Example:
"xxxxx.yyyyy.zzzzz"
Think of JWT like a signed digital ID card.
The server can verify that it was issued by it and hasn’t been tampered with.
📌 Remember:
JWT ≠ encryption.
The payload is usually readable. The signature provides integrity/authenticity.
Save this if you're learning backend development.

134-day streak.
16 badges. 🏆
No shortcuts.
Just wrong answers, failed approaches, late nights, self-doubt, and showing up anyway.
There were days I wanted to quit.
I didn’t.
Still learning.
Still solving.
Still getting better.
What’s your longest streak?

You use a browser every day.
But do you actually know what’s happening inside it?
Browser ≠ just a website viewer.
Think of it as:
Browser = JS Engine + Web APIs + Rendering Engine
→ JS Engine → runs JavaScript
→ Web APIs → DOM, fetch, timers, events
→ Rendering Engine → turns HTML/CSS into pixels
That’s how your code becomes an interactive webpage.
Which is your favourite browser??

e-commerce system architecture
here’s how a basic e-commerce backend can work:
→ user / client
web or mobile app where users browse, search, add to cart and place orders.
→ dns + load balancer
dns resolves the domain, while the load balancer distributes traffic across multiple backend instances.
→ api gateway
single entry point for routing, authentication, rate limiting and request handling.
→ backend services
separate services handle:
• users & authentication
• products & search
• orders & checkout
• payments & refunds
• inventory
• notifications
→ databases
each service can have its own data store, making it easier to scale and isolate workloads.
→ redis
caches frequently accessed data like product details and sessions to reduce database load.
→ object storage
product images and files live in s3/minio instead of bloating the database.
→ message queue + workers
slow background tasks like emails, invoices and notifications can run asynchronously.
→ cdn
serves static assets and images faster from locations closer to users.
→ monitoring + backups
metrics, logs, alerts and database backups help keep the system reliable.
the real learning starts when you ask:
what happens when traffic goes from 1k → 1m users?

government/psu job > mnc job.
stable job, peace of mind, decent money, strong benefits, and no constant fear of layoffs. a slightly lower salary can still be a better deal when your expenses are lower and your job actually gives you financial security.
would you choose stability over a higher package?
