Primitive Recursive Functions For A Working Programmer

Programmers on the internet often use Turing-completeness terminology. Typically, not being
Turing-complete is extolled as a virtue or even a requirement in specific domains. I claim that most
such discussions are misinformed --- that not being Turing complete…

Non-temporal stores (and _mm_stream operations in stdarch) break our memory model · Issue #114582 · rust-lang/rust

I recently discovered this funny little intrinsic with the great comment Emits a !nontemporal store according to LLVM (see their docs). Probably will never become stable. Unfortunately, the comment...

C Macro Reflection in Zig – Zig Has Better C Interop Than C Itself

Zig’s reflection combined with Zig’s ability to import C header files means Zig can be used for C macro reflection.

⚛️ Apple 正式开启 Apple Intelligence 测试

Apple 在今日凌晨发布 iOS 18.1 第一个开发者测试版，开始启动对 Apple Intelligence 的测试。一直苦等 iOS 18 真正新特性的小伙伴坐不住了，希望第一时间尝试。

💡 新能力解锁
目前在 iOS 18.1 beta 1 中解锁的功能如下：

* 通话录音：会用 AI 的声音告诉你“我正在录音，请注意”。和 Zoom 会议中开启录制效果类似。

* 智能改写：可以将你输入的部分用 AI 重写，调整语气，调整篇幅长短等等。

🔒 冤种用户：锁硬件
目前为止 Apple Intelligence 为硬件锁，如果你的设备是在中国大陆、欧盟购买的，那么无论你的地理位置、IP 地址是什么，你都无法使用 Apple Intelligence 的任何功能。

香港和澳门不受影响；英国因为脱欧，因此也不受影响。Apple 可能后续会调整政策。

⬆️ 更新至测试版
如果你只希望更新 iOS 18 系列的 beta，不想更新至 macOS Sequoia，而且又怕 OTA 更新不稳，希望通过线刷的方式升级.

没关系，我帮你提取了最新 Xcode 的设备驱动，只需要在当前 macOS 安装这个驱动，你就可以通过 Finder 将 iPhone 升级至 iOS 18 系列测试版了。 详见评论区
