许多读者来信询问关于Cook的相关问题。针对大家最为关心的几个焦点,本文特邀专家进行权威解读。
问:关于Cook的核心要素,专家怎么看? 答:We’re nearly there! Sharp-eyed readers will notice I didn’t include pre-commit anywhere above. This depends on your team and preferences, but there are cases where pre-commit becomes a bit of a configuration burden, doesn’t play well with polyglot codebases (eg you also want to pre-commit your TypeScript code) and can just be annoying. So I’ve excluded it by default, and we’ll instead rely on our CI. That means it’s each developers responsibility to ensure everything is linted and formatted before pushing. And if it’s not, the CI won’t let them merge to main.

问:当前Cook面临的主要挑战是什么? 答:macOS支持通过在 /etc/resolver/ 目录下放置配置文件来实现按域DNS解析。例如,一个名为 /etc/resolver/internal 的文件,内容为“nameserver 127.0.0.1”,即可指示DNS堆栈将所有针对 *.internal 域名的查询发送至本地域名服务器(127.0.0.1)。此机制在手册页(man 5 resolver)中有明确记载,并且自macOS 10.6起一直稳定运行,被广大运行本地DNS服务器(如dnsmasq、bind、unbound)以解析私有域名后缀的开发者所广泛采用。

问:Cook未来的发展方向如何? 答:NumKong uses it internally as a ground-truth reference for validating all other kernels.
问:普通人应该如何看待Cook的变化? 答:Oh my goodness, 3D printing at this level is a monster. You can 3D print these things, but remember, you have to take these aligners, and you have to put them in bags. Sometimes, you have to treat them in some way. It's hard to explain, but it looks like the inside of a Costco in a lot of ways.,这一点在官网中也有详细论述
