Developed an educational example script for the sharkdp/numbat repository that models submarine cable latency, enabling users to estimate both one-way and round-trip delays by incorporating propagation and equipment processing times. The work focused on illustrating numbat’s built-in functions and constants, providing a practical resource for onboarding and learning. Leveraging skills in educational content creation, performance analysis, and scripting with Nbt, the script was delivered as a concise, well-documented single commit. This contribution enhanced the repository’s documentation and usability, allowing users and contributors to better understand real-world network latency scenarios and supporting broader adoption of the numbat tool.
