Every outward circumstances, thought, feeling, and so on is guiding us inward to discover who we truly are.

Nowadays, love has become like a contract—when the agreement ends, love also ends. But true love is compassion, where ‘I’ and ‘you’ dissolve into one. When a person sees their own reflection in others, that is when real love shines.

[Abhinandan Gayaki @abhiG0]

Grow yourself like a tree by nourishing with the water of love, not the poison of hate.

[Abhinandan Gayaki @abhiG0]

We see someone and start comparing—who is more powerful, wealthier, or smarter—and then begin chasing those qualities. But in that chase, we lose the true identity that life has already given us.

@_jaydeepkarale Thanks Jaydeep, Appreciate your work

[Abhinandan Gayaki @abhiG0]

Desire is contraction, and love is expansion of life. Both are necessary, for without contraction there can be no expansion, and without expansion there can be no contraction.

Why don’t we use CDN for backend?

→ Because backend responses are dynamic and user-specific, so caching won’t work.

[Abhinandan Gayaki @abhiG0]

Deploying frontend on AWS? Here’s the simple flow you need to know ��

[Abhinandan Gayaki @abhiG0]

Solution → CloudFront (CDN)

1) Caches content at edge locations

2) Reduces latency

3) Provides a secure global URL for your content

🚀 Cloned repo & ran backend app on EC2 machine

🌀 Reverse Proxy (Nginx) → Learned why it hides ugly URLs & lets backend + frontend share a port.

📝 AWS Learning Today

☁️ AWS → Rent servers, manage domains, autoscale infra.

⚡ EC2 → Elastic = scale up/down, Compute = processing power. Comes with IP + Elastic IP (stays same even if server restarts).

[Abhinandan Gayaki @abhiG0]

🛠 cgroups (Control Groups)→ Control, limit & prioritize resource usage.

🔑 Launched my first EC2:
 1️⃣ Picked OS + version
 2️⃣ Chose instance type
 3️⃣ Created key pair
 4️⃣ Opened ports 22 & 3000
 5️⃣ Added 16GB storage
 6️⃣ SSH’d in: ssh -i demo.pem ubuntu@<ip>

Key-based: more secure Use ssh-keygen to generate keys. We can share public key with everyone but Keep private key secret!

7/ Key-based SSH = better security + no passwords!

🧵Today's Learning: VMs, Hosting & SSH Basics 🧠🌐

1/ Why deploy on the internet?

Because localhost is local only. Nobody outside your device can access your app/site unless it's publicly available.

2/ Domain name vs IP

IP: Your real address
Domain: Human-friendly name

[Abhinandan Gayaki @abhiG0]

5/ OSI Model A 7-layer model that explains how data moves through networks.

Learn the basics: Application, Transport, Network, Data Link...

6/ SSH Authentication
Password-based: easy but less secure
