Hi, I’m Alexandre 👋

Also known as Dpbm, welcome to my little corner of the internet.

This blog is my personal vault—a place where I write about the things I’m learning, building, and experimenting with. You’ll find posts on computer science, electronics, mathematics, machine learning, quantum computing, and whatever else sparks my curiosity.

I’m a computer scientist currently pursuing a master’s degree. My main interests are quantum computing, low-level programming, and machine learning, but I enjoy exploring just about anything related to computers.

My goal is simple: document what I learn, share the projects I build, and hopefully make someone else’s learning journey a little easier.

Happy reading! 🚀

Understanding QFT in a simpler way

QFT is such an important piece in the filed of quantum computing. Understanding it is important to master most part of quantum algorithms, so let’s dive in.

Multiple Operating Systems in Superposition

Are quantum computers turing complete?

Let’s reason if it’s possible to have a general quantum computer like we have with classical

QAOA the simple way

I always struggled with understading deeply the QAOA algorithm, so now I want to pass my understanding in a simpler and more applied way. Basically a way a computer scientist would understand.

Wavelets and their applications in image processing and feature extraction

The processing tool nobody talks about!

This semester many things happened, discover some interesting stuff about my masters and how Wavelets are amazing in so many ways, including feature extraction and image processing!

OpenWRT is like magic

I’ve been working in some projects and for a specific problem I needed to have more control in my network. I need to setup more advanced stuff, like more specific routing rules, etc. I could have done that on my router, but it could affect the usage for my family. So, thank god, I’ve got some old TP-Link routers as a gift from a friend, who was trying to get rid of this “junk”. ...

Wavelets for processing images - Kinda cool I'd say

Well, my course on Wavelets transform is reaching the end, which is pretty sad. When I was choosing the subjects to study this semester, this one was the strangest to me, I had never heard of such a topic like that, actually I had heard of DSP for trading and whatever, but never had a formal knowledge on that. Now, that I have a more solid foundation on the topic, I can say that I have no regrets on choosing it. It’s so interesting in so many ways. ...

Mallat's algorithm with cuda - Everything I've learned with it

As I pursue my master’s in computer science as by now a non-degree/special student, I decided to attend to two different classes this semester: Algorithms (because I like it) Wavelet Transforms (because it seemed interesting) Algorithms is a pretty well know topic in computer science which you may be familiar with. Everywhere and, weird or not, every class may be related to algorithms in some way (even my wavelet class). For this semester, we learned about some ways to calculate and analyze code to find bottlenecks, performance issues, possible improvements. In general, we learned about asymptotic behavior/analysis, so big O notation and its relatives θ and Ω. I’d like to talk more about this, so I’ll hold this topic for a future post. ...
