This month, OpenAI announced their Codex app and my coworkers were asking questions. So I downloaded it, and as a test case for the GPT-5.2-Codex (high) model, I asked it to reimplement the UMAP algorithm in Rust. UMAP is a dimensionality reduction technique that can take in a high-dimensional matrix of data and simultaneously cluster and visualize data in lower dimensions. However, it is a very computationally-intensive algorithm and the only tool that can do it quickly is NVIDIA’s cuML which requires CUDA dependency hell. If I can create a UMAP package in Rust that’s superfast with minimal dependencies, that is an massive productivity gain for the type of work I do and can enable fun applications if fast enough.

白天的香港依靠制度、合同和效率运转，夜晚则容纳人情、默契与试探。很多话不适合在写字楼里说得太直白，却可以在包厢里慢慢铺开，很多关系无法写进合约，却能在一晚又一晚的往来中被确认。夜总会正是这种灰度空间的集中体现。它高度有序：服务流程、座次安排、消费结构、陪侍规则形成一整套成熟系统，这些规则也不写在纸面上，依赖经验与长期互动维系。
