Cybersecurity Cryptography Linux Software Engineering

Over the years, my technical blog has served as a digital lab notebook—a place to document deep dives into complex systems, share security research, and build tools that solve real-world problems. Spanning from 2020 to today, the archive contains hundreds of articles that reflect a journey through the ever-evolving landscape of technology.

If you’re new here or looking back at the archives, here’s an overview of the core pillars that define the research and writing found on this blog.

Cryptography & Security Research

Security is at the heart of my work. Much of my writing focuses on the technical design of cryptographic functions and the analysis of security mechanisms. Some key areas include:

  • Argon2 & Password Hashing: Detailed analysis of memory-hard functions, GPU optimization, and cracking resistance.
  • Vulnerability Research: Bypassing modern protections like Windows 11 Administrator Protection and exploiting high-integrity UI access.
  • Network Security: Deep dives into Palo Alto Cortex XDR, including decrypting predefined BIOC rules and finding ways to circumvent them.

Linux Systems & Observability

I have always been fascinated by how operating systems work under the hood. My Linux-focused articles explore the “roentgenogram” of a system:

  • Observability: Moving from strace and ltrace to high-performance observability with eBPF.
  • Hardware Analysis: Using tools like perf for CPU profiling and analyzing hardware components on Linux.
  • Kernel Internals: Understanding memory management, the OOM Killer, and blocking I/O from a syscall perspective.

Software Development & Automation

I believe in building tools that automate the mundane and enhance productivity. This blog documents the development of various projects:

  • AI-Driven Tools: Projects like Repomix, which packages entire codebases for AI consumption, and experiments with AI-driven coding agents.
  • Telegram Ecosystem: A long list of open-source Telegram bots designed for mirroring, leaching, message cleaning, and automated file management.
  • Custom Utilities: Tools like Oget for offline Ollama model installation and MetaClean for privacy-focused video merging.

Linux Guides & The Arch Linux Experience

A significant portion of my archive is dedicated to making complex Linux setups accessible. From installing professional software like Adobe Photoshop 2025 and IDA Pro on Arch Linux using Wine/Steam, to troubleshooting VMware or setting up specialized network tools like Zapret and GoodbyeDPI to bypass censorship.

A Growing Archive

With over 100+ posts ranging from 2020 to 2026, this blog is more than just a collection of tutorials. It is a record of continuous learning, from the basics of Prime Number algorithms in C++ to the cutting edge of Windows kernel exploitation.

Whether you are here for the deep-dives into Argon2 or just looking for a way to fix your wireless drivers on Arch, I hope you find something that sparks your curiosity.

Stay curious, stay secure.
