Hi, I’m claud3, a master’s student in Cybersecurity Engineering.

I’m passionate about cybersecurity in general, and I’m currently on a mission to figure out which specialization or niche field fascinates me the most.

At the moment, I find wireless and physical layer security particularly interesting. It’s an area that isn’t talked about as much when people think about cybersecurity, yet it sits at the intersection of mathematics, physics, signal theory, networking, and computer science. That combination makes it especially intriguing to me.

But what I enjoy the most is trying to find ways to “hack” the systems I study, not necessarily in the malicious sense, but in the sense of understanding them deeply enough to gain control over them and explore how they behave when viewed from a different perspective.

About this blog#

This blog is essentially a technical notebook.

Here I document experiments, projects, and ideas that intrigue me. Many of them are things that might be a bit unusual in a classroom environment, or topics that go slightly beyond the standard curriculum.

The goal is not only to learn new concepts or technologies, but also to learn more about myself and what truly interests me within this field.

Curiosity is the most important thing for me. As long as I keep exploring new ideas, experimenting with new tools, and diving into unfamiliar topics, I know I am moving in the right direction.

Why the name d1racpuls3?#

The name of this website comes from something I learned early in my signal theory course: the Dirac delta, also called Dirac Pulse.

It’s often written like this: $ \delta(t) $

What makes it interesting is that it’s not really a normal function. The Dirac delta is more like a mathematical trick that engineers use to describe very short impulses.

You can imagine it as an infinitely small pulse that somehow still contains energy. It’s not something that physically exists, but it turns out to be incredibly useful for describing signals.

And signals are everywhere: music, videos, radio transmissions, Wi-Fi, digital communication, pretty much everything that moves information around the modern world.

When I first encountered this concept, I found it fascinating that something so abstract could be such a fundamental tool behind technologies we use every day.

So the name d1racpuls3 is a small reference to that idea.

This blog is a bit like a series of small impulses too: projects, experiments, and random ideas that pop up when curiosity hits.

Over time, those little pulses hopefully build into something bigger.
