MDN Report A+

20 May 2025

Ran my site through MDN’s security scanner and kept tweaking until I hit 120/100 (A+).

Checked the scan history and the very first one, back in 2018, scored 20/100 (F).

Always improving.

Real-time Deepfakes: what if "seeing is believing" no longer means anything?

10 May 2025

An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason.

With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required.

The implication is clear: you can no longer trust a video call at face value.

So here’s the question: how do we verify identity in a world where faces can be forged on demand?

If you’re not using GPG to sign or encrypt your files and messages yet, it’s time to reconsider. It’s not just about looking like a 90s movie hacker — it’s about protecting your communication and digital identity in an increasingly hostile world.

Shadowdata Sensitive Data Handler Python Library

12 Oct 2024

I am deeply concerned about how to handle sensitive data in the projects I work on. Nowadays, there are laws in various countries addressing this issue, and the topic becomes increasingly important as time goes on.

Therefore, I decided to create a Python library that can help me deal with scenarios where it is necessary to process data to prevent any individual from being identified if the information is accessed. The library also handles data transformations, encryption, and the detection of sensitive personal data.

Sudo with Touch ID on macOS

Setting up sudo for use with Touch ID on macOS Sonoma in just a few steps is very easy.

Locate the file /etc/pam.d/sudo_local.template and make a copy as shown in the example below:
