Pushing the Pico - D3d_Dr0p and Hyperlocal E-Graffiti

I've recently discovered that Raspberry Pi Pico W's, a tiny microcontroller with a wireless chip, are only $6 a board, a price so low that my mind created a myriad of projects around it that I just had to start on. So, as any rational human would do, I bought

A builder's approach to content creation

I did some introspection recently and came to the conclusion that I've been going about most things wrong, despite finding what some might call success in a lot of my ventures. I've been a... content consumer? for quite some time now. I was watching YouTube pretty early on in the

Rust Snippets #0 - The Windows Function

This is the first in an ongoing log of easy/simple/esoteric methods, functions and patterns in Rust that will (hopefully) make your life easier. I'm writing it in parallel to a similar series in Python, the first post of which you can find here. This article is all about

Project-Oriented Learning, or How to Learn Anything

I've talked about it before that one of the things that drew me to computer science versus physics, chemistry, biology or any of the other popular sciences is the opportunity for fast, iterative and virtually free (often actually free) experimentation. Chemistry often requires an expensive lab and tons of safety

Learning Rust - Rust Book Chapters 1-3

I've been writing Rust for a couple of months now but noticed I was quickly starting to run into a lack of knowledge on some foundational topics that was leading to frustrating bugs and annoying dead ends. So, instead of trying to forge ahead in the hopes that I could

Python Snippets #0 - Array Slicing

This is the first of an ongoing and probably infrequent series on Python snippets, or short, basic hints for Python to make your developer life easier. This one is incredibly basic: array slicing! Array slicing, or the syntax to create sub-arrays from input arrays, is an incredibly useful concept that

Road to OSCP 0x0 - Starting the Road to the PNPT

This is the year that I'm finally going to conquer the OSCP. I've talked about my plan for studying for the OSCP in a YouTube video, but I'll rehash it a bit here on the blog as well. The plan is to study up for the PNPT, or the Practical

Learning Rust - Lifetimes and Scope

I've been livestreaming malware development in Rust several times per week over the last two weeks over on YouTube and Twitch. There was a bit of consternation about me switching over to Rust early on: a lot of people really wanted to see me stick it out with C/C+

How Malware Works

I had a question on one of my posts on YouTube that made me realize that some people may not be super familiar with some of the terminology surrounding malware development and reverse engineering. This isn't meant as a shame on the OP, moreso a failure on my part (and

How to develop good malware (and software in general)

I'm going to preface this article with stating what is obvious by anyone who has watched my videos or livestreams on YouTube: I'm not a good malware developer. I'm trying, and I've gotten better, but anyone who has watched my  content or read my blogs on the subject knows it's

Malware Dev Environment 1 - Learning Makefiles

In my most recent iteration of my Reverse-Reverse Engineering series, I decided to ditch the VisualStudio set up and go with a more traditional C/C++ development set up. This is both because I didn't want to become super dependent on the MSFT stack and because I wanted to learn

Why I'm moving to the Fediverse
