Sprints in real life means you run very fast, then reach finish line , then stop and take a long rest to recover the list energy.

Sprint in corporate means you restart the sprint once finish and it’s is a never ending cycle exhausting you

i have lost meaning. nothing feels difficult anymore.

earlier, there was so much joy in writing code by hand - finding problems, staying awake for hours just to solve that one silly bug buried deep in the code.

coding gave me a lot of joy, but with agentic coding, writing code by hand no longer makes sense - not because i want it that way, but because of the pressure from everyone around you. why struggle for hours when you can finish everything at 100 toks/sec?

it has left a dent in that joy i once carried. i wish i could go back to writing pure code with my own hands - no agentic coding at all - but there is no time for that. features need to be shipped quickly, and if you don't keep up, you get crushed by others who do.

some might say, "you still have to read the code and figure out if it's correct." that's true, but reviewing something is very different from actually writing it. the neurons fire differently for both - and they fire far more when your fingers are hitting those keys on the keyboard.

maybe the craft isn't dead, but it is slowly being asked to wait in the corner - and for those of us who fell in love with the process, not just the output, that silence is louder than any compiler error ever was.

Every idea feels taken.
Every API already exists.
Every SaaS has 12 competitors.

So what do we even build now?

Nostalgia is the best and worst feeling sometimes.

This is why we say Node.js is "asynchronous I/O" or "non-blocking I/O". It's not blocking your main single thread - it gets offloaded to libuv, and async operations don't hold up your code execution.

🧵Why Node.js is called "asynchronous I/O" or "non-blocking I/O"?

[Anuj nema @letscodeanuj]

When your JS code hits async operations (file reads, DB queries, timers), Node doesn't block. It delegates to libuv, and when libuv finishes, it pushes from callback queue back to the call stack.

But, Where does require() come from?

Answer - It’s also passed as a parameter to the wrapper function.

it’s normally gets injected by Node.

as show in previous image too. These are the arguments that gets passed by node.

Ever wondered why you can’t just import a function and access everything inside a module directly?

[Anuj nema @letscodeanuj]

And we take module from the parameters exports our function or variables👇

🔁 How They Work Together

Your device sends a request to your router when visiting a website.

The router uses NAT to map your private IP to the public IP

The website response to your public IP, and the router forwards it back to your phone.

1️⃣Network Fundamentals

🧠 What is an IP (IPv4/IPv6)?

IP Address is like your digital adddress that identifies your device on the internet.

Example: 192.168.0.1

🏠 Private IP Address

It is the address assigned by your router to your device (Phone, TV or PC)

It is used within your local network.
