1. 快餐文分享: M1 暴打 Intel？——x86 与 ARM 的爱恨情仇 <https://blog.liangyueyong.cn/p/b013.html>

   摘要: 事实上，CPU 做的事情很简单也最核心，简单来说就是接收指令+运算。CPU 和千千万打工人一样，首先要有正常的**工作能力**（即执行能力/运算能力），然后又有足够的**逻辑能力**（能明白做事的顺序），最后还要有一定的**理解能力，能听懂别人的话**（即指令集），才能正常工作。而把这些**集中在一起**就构成了所谓的「**架构」**。你可以将「架构」理解为一&#x5957;**“工具”、“方法”和“规范”的集合**。
2. 好文分享: A Brief Notebook on Cryptography <https://davidlowryduda.com/a-brief-notebook-on-cryptography/>

   摘要: Recall the basic setup of cryptography. We have two people, Anabel and Bartolo. Anabel wants to send Bartolo a secure message. What do we mean by “secure?” We mean that even though that dastardly Eve might intercept and read the transmitted message, Eve won’t learn anything about the actual message Anabel wants to send to Bartolo.

   文章讲述了密码学的历史发展, 以及现在常用的RSA非对称加密原理, 并都给出了代码实现, 非常建议阅读.
