相比之下，我们这种埋头蹲 https://source.chromium.org/ 看源码的，真的好傻好天真。。。

学习了，

围观学习

@jackrelative 原来是 webview 套壳啊，我终于知道 v 站网友说的副业是啥了。。。

@chengkai 合议庭如果认为不需要开庭，直接就书面审理了（驳回上诉

你还和法官讲这些，法官一是可能根本不懂，二是也根本不在乎。。二审可能庭都不用开，直接就维持原判了

@cht1995 真巧，我也在某个论坛用过 Herb Sutter 的头像...

## Native FP16 on Apple M1, 来自 Steve Canon (Apple Swift team)

A couple random fun numerics things to play with on M1 macs:

- native half-precision arithmetic
- ARMv8.3 complex arithmetic SIMD instructions

## ARM x86 关于 Memory model 的区别，来自 Bruce Dawson (Google Chrome Team)

mov register-> a
mov register-> b

On x86/x64 the store to "b" is guaranteed to not be visible to other processors before the store to "a". On ARM that is not guaranteed.

Many benign x86/x64 data races will becomes real bugs on ARM, and it appears many programmers don't know this

The emulator _must_ emulate the x86/x64 memory model. It is as important as properly emulating the CPU status flags and arithmetic instructions. So, yes. If Rosetta didn't emulate the memory model it would not be an x86/x64 emulator.

「不测不知道，一测吓一跳。可以看到 M1 尽管是用 Rosetta2 模拟运行的 x86 Dota2，但这帧数，整整领先 Intel Iris 三倍之多。」

@hello2060 冬天的使用场景就靠 cpu 当暖手宝了，这以后还怎么整

大佬火速来一把原神试试。。

不仅不耗电，还能用爱发电（多余电量并入国家电网

还有很多更可怕的 zero-click RCE，大家都别用手机了呗。担心被黑客用几百万刀的 0day 定点打击之前，先照镜子看看自己配不配。

Time travel 吗？
