Documenting my journey through Linux, DevSecOps, and cybersecurity.
Hi, I'm Bui Vo Phuoc Thinh, also known as Notoxus. I'm an IT student passionate about Linux systems, infrastructure automation, and cybersecurity. This blog is where I document what I learn — from homelab experiments and Linux administration to networking, DevSecOps, and security labs. Most articles are written in Vietnamese or English as I continue learning and building along the way. Thanks for stopping by!
