当前部分博导反映的博士生源质量下降的问题，根本原因不是“申请—审核”制，而在于博士大幅扩招。道理很简单，如果申请的学生质量普遍不行，把“申请—审核”制改为“考博制”就能提高生源质量吗？更需要追问的是，如果对来申请读博的学生质量不满，有招生自主权的博导为何要招呢？这就是“为招生而招生”了。。爱思助手下载最新版本对此有专业解读
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.
