让荣光落于刀锋之上: On behalf of the LLVM Project Council, Alex Zinenko provided an update on the MLIR Project Maintainers nominations. The proposed category maintainers are moving forward, but proposal of "Lead MLIR Project Maintainers" is awaiting further clarity on the scope of responsibilities.
这名字ID我感觉有点容易被误解违反CoC,嘶~ "isuckatcs" shared initial results from a Clang summary-based analysis prototype.

本周推荐:《天气预报:一部科学探险史》

我们每个人手机里随时可以查询的天气预报,是人类科学历史上群星闪耀的注脚。许多项看起来没有相关性的技术,出于兴趣、偶然、竞争、荣誉、好奇心等各种理由被发现、被推敲组合,并在发明的很久之后,有一个完全不被预测到的人以一种令人恍然大悟的方式组合在了一起。
这是一本科学和技术拓荒者的群像故事。你甚至可以看到达尔文和小猎犬号。
