Does equality in $\Sigma_{(x : X)} x = x$ implies UIP?
The short version:
Is this statement correct? If it is, is it provable in Coq?
Definition id_at { X : Set } ( x : X ) := x = x.
Definition id_at_eq_refl { X : Set } { x : X } ( p : x = x ) := existT

npmjs.org 被用来托管《武林外传》视频及弹幕。
- Sonatype 发现 npm 上的 748 个包名以 wlwz 开头的包里的 .ts 文件并不是 TypeScript 源代码,而是视频文件 (MPEG-TS)。
- 虽然文章中没有写明,但中文订户大概能看出视频的内容是《武林外传》剧集。

咨询群友有无防水耳机推荐
我的 NANK Runner CC 3 又又又坏了
Prefers:
- 需要 >= IPx7 本来想要找充电盒也防水的,找不到放弃了
- 如果是骨传导耳机,价位大约 500 以内,最好是磁吸充电
- 骨传导以外的就没什么严格限制了,因为音质感觉不会太糟糕
