Alireza Ghaffari
Developed system monitoring capabilities for the DuckDB community-extensions repository by building the Sazgar extension in Rust, adding cross-platform telemetry and a suite of SQL table functions for resource observability across host and container environments. Leveraged the sysinfo crate to provide detailed CPU, memory, disk, and network metrics, including Docker container monitoring and unit conversion enhancements. Improved data handling, documentation, and release stability through configuration management and continuous integration. Additionally, addressed a security issue in the marimo repository by updating the Referrer-Policy to 'same-origin' using Python and YAML, ensuring secure referrer handling and improved cross-browser compatibility on macOS.
