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.

"This is a time when you think, 'Thank God the US doesn't have a state-owned oil company,'" she says. "They need the private sector, but for the moment, the private sector isn't budging. And what company in their right mind is going to put money into Venezuela?"，推荐阅读91视频获取更多信息
Therefore, the kernel maintainers are working to replace this fragile PGP key‑signing web of trust with a decentralized, privacy‑preserving identity layer that can vouch for both developers and the code they sign.
