Explaining how computers really work—from logic gates, CPUs, memory, C Language, and Linux to RISC-V, ARM, x86, AI, and large language models.

Dennis Ritchie wasn't trying to create one of the world's most important programming languages. he was trying to build a better language for Unix.
Ken Thompson's B was too limited for the new PDP-11, so Ritchie started adding types and building a real compiler.
That became C. the first version was built on a machine with just 24 KB of memory.
Decades later, C is still running the world.

Why is every tech giant hoarding GPUs right now? 🤖💡
It comes down to one core architectural difference:
1️⃣ CPUs prioritize low latency (running sequential logic as fast as possible).
2️⃣ GPUs prioritize high throughput (running thousands of parallel threads at once).
Turns out, rendering 3D pixels in video games requires the exact same math as training LLMs.
Once you understand the hardware-software boundary, the entire AI stack finally makes sense.

LLMs Don’t Need GPUs Anymore? 17,000 Tokens Per Second!

How Linux Works
youtu.be/9PkIYK9tdAI?si=NU-E…
A simple ls command travels through:
User
↓
Shell
↓
fork()
↓
execve()
↓
Kernel
↓
VFS
↓
Page Cache
↓
Filesystem
↓
Terminal
before you see the result.
Most users never realize how much happens behind a single command.

How Linux Architecture Works ?
youtu.be/KNw5b8emVpU
A simple Linux workflow looks like this:
User enters a command in the shell
The shell interprets the command
System libraries translate requests into system calls
The kernel processes the request
Device drivers communicate with hardware
Results return back to the user application

Google just dropped a quantum bomb 💥
Their new chip Willow solved a problem in <5 minutes
That would take a supercomputer 10 septillion years
Now people are asking:
Are quantum computers tapping into parallel universes?
Reality:
No proof of that.
But something big is happening. ⚡

The future of computing isn’t one technology.
It’s a WAR of paradigms:
| Hardware | Strength | Weakness |
| GPU | Massive parallel AI | Power hungry
| FPGA | Ultra-low latency | Hard to program
| Quantum | Exponential scaling | Not practica
