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.

Webb's sharper view also hints at possible jets from the central star. The dark lane and the way gas appears to push outward near the top of the nebula suggest an ejection that may be shaping the cloud's symmetry, a common feature when aging stars throw material in opposite directions.
日记的后半段，随着塔可夫斯基步入流亡岁月、病痛缠身，文本中蕴含的情感层次也愈加丰富，欢喜、愤怒、迷茫、思念、绝望交织，这对翻译提出了更高的要求——不仅要保证语言的精准，还要反复琢磨某些表达方式背后的心理动机，让这些细腻而浓烈的情感得以准确传达。日记天然的私密化特征，让翻译成为一场视角与价值观的碰撞，成为一次与塔可夫斯基的深度对话。李芝芳钟爱《伊万的童年》的主演布尔利亚耶夫，也敬仰掌镜塔可夫斯基前两部影片的苏联摄影师尤索夫，可在塔可夫斯基的日记中，这些业内公认的一流电影人，都因创作矛盾而遭到了他毫不留情的指责和挑剔：布尔利亚耶夫因《安德烈·卢布廖夫》的拍摄安排与他决裂，尤索夫也在《镜子》的创作中与他分道扬镳。“这些人在我们心里都是标杆，在他的日记里，就没有一个不骂的。”李芝芳的笑谈道出了翻译时的挣扎。。关于这个话题，同城约会提供了深入分析
