“以前，我们只能通过几十厘米的小装置进行验证，而这里的装置尺寸大几十倍，我们能研究更复杂的物理过程。”2025年3月，中国科学技术大学陆全明教授团队与哈尔滨工业大学合作，首次在实验室实现了地球磁层顶位形磁场重联过程的地面模拟和确认。
The language is pure, lazy, and has no loops. Every iteration is recursion, and recursion costs stack frames. Since Nix 2.20, the evaluator caps call depth at 10,000 (configurable via max-call-depth, but the default is what you'll hit). Before 2.20, the limit was whatever your OS allocated for the process stack: non-deterministic across machines, occasionally baffling to debug. Tail-call optimization would help. There's even a FIXME comment in ExprApp::eval() acknowledging it. But the evaluator's structure (a local variable that stays live across the recursive eval call) prevents the tail position from being optimized, and nobody has restructured the code. Tvix, the Rust-based evaluator, handles TCO in many cases. The reference C++ evaluator doesn't.。新收录的资料对此有专业解读

Not that getoffmydickerson is Durant’s only problem. Shortly after the tweets blew up, Boardroom, which defines itself as a “sports, media, and entertainment brand” co-founded by Durant and his agent Rich Kleiman, laid off three of its staff writers, rationalizing the move as part of a pivot to video. (An aside: what’s the point of having career earnings of half a billion dollars if you’re not willing to invest some of it to protect your media company from financial headwinds?)，这一点在新收录的资料中也有详细论述
In one of his surveys, he asked if photographs of various subjects would more likely give a photo that is ugly, meaningless, interesting, or beautiful. Less-educated people thought a first communion would be beautiful and the bark of a tree would be meaningless. Highly-educated people thought the opposite.
