ryuru is a technical blog focused on low-level systems, networking, and security engineering.
The writing here tries to do one thing well: take concepts that are usually buried in dense documentation or oversimplified into uselessness, and explain them in a way that’s actually clear. Not watered down. Not rigidly academic. Just practical knowledge you can sit with and apply.
Most articles cover concepts from three angles: diagrams to show structure, text to explain the reasoning, and code to make it concrete. The language varies depending on what fits. C++ where performance and control matter, Python where readability does the job.
The articles follow a roadmap structure, not a random collection of posts. The ryuru-labs repo on GitHub mirrors that order. Each article links its scripts there, so you always know where you are and what comes next.
