Just tried an iPhone 12 Pro – what an incredibly clunky piece of hardware. It looks and feels like an oversized version of an iPhone 5 from 2012, but with an ugly array of cameras sticking out at three different heights. The notorious notch and wide bezels are still there, creating a low screen-to-body ratio and general outdated feeling for the device.
9 years after Steve Jobs died, the company is still living off the technology and reputation he built, without any meaningful innovation. It’s no surprise iPhone sales were down by 21% earlier this year. If this trend continues, in 7-10 years time the global market share of iPhones will be negligible.

管理堆内存，Rust是怎么做的？所有权！
本篇谈下Rust语言的核心概念：所有权。这个概念是支撑Rust在编译期做内存安全检查的核心机制，也正是因为这个特性，我们认为Rust是内存安全的底层语言。虽然带GC垃圾回收器的语言虽然也是内存安全的，但由于GC的存在，已与底层无缘。栈和堆当说到语言的内存管理时，通常指的是对于堆的管理，而栈的使用都是自动的，通常都不需要程序员特别关心。栈栈，是一种数据“后进先出”的存取方式，速度非常快。《Rust权
