This repository contains materials for various tech talks I have given in Hong Kong.

• python/narwhals-demo -A demo of dataframe interoperability using the Narwhals library. Presented at Python User Group Meetup in August 2025 (City University of Hong Kong).

• rust/polars-demo - A demonstration of using the Polars data science library in Rust. Presented at the Hong Kong Rust Meetup in December 2024 (Mantra).

You can pull the desired talk with this command

curl -sL shorturl.at/zoafl | bash -s -- [name] && cd talks/[name]

Where [name] is the directory name.

For example, for the narwhals-demo, you would run:

curl -sL shorturl.at/zoafl | bash -s -- python/narwhals-demo && cd talks/python/narwhals-demo
