截一断我极客时间专栏中跟Paxosssh相关的一节
Paxos算法，是莱斯利·兰伯特（Lesile Lamport）于1990年提出来的一种基于消息传递且具有高度容错特性的一致性算法。但是这个算法太过于晦涩，所以一直以来都属于理论上的论文性质的东西。其真正进入工程圈，主要是来源于Google的Chubby lock——一个分布式的锁服务，用在了Bigtable中。直到Google发布了下面这两篇论文，Paxos才进入到工程界的视野中来。
• Bigtable: A Distributed Storage System for Structured Data
• The Chubby lock service for loosely-coupled distributed systems
Google与Bigtable相齐名的还有另外两篇论文。
• The Google File System
• MapReduce: Simplifed Data Processing on Large Clusters
不过，这几篇文章中并没有讲太多的Paxos算法上的细节，反而是在 Paxos Made Live – An Engineering Perspective 这篇论文中提到了很多工程实现的细节。这篇论文详细解释了Google实现Paxos时遇到的各种问题和解决方案，讲述了从理论到实际应用二者之间巨大的鸿沟。
Paxos算法的原版论文比较晦涩，也不易懂。这里推荐一篇比较容易读的——Neat Algorithms - Paxos 。这篇文章中还有一些小动画帮助你读懂。还有一篇可以帮你理解的文章是Paxos by Examples。

不知Snowden 的一個有趣的項目為何沒有太多關注 https://github.com/guardianproject/haven 其實我用下來很不錯，而且真是廢物利用

14 Patterns to Ace Any Coding Interview Question | HackerNoon
The process of preparing for coding interviews is anxiety-inducing for many developers. There’s so much material to cover, and often much of it feels irrelevant to what devs are doing in their day jobs, which only adds to the stress.

最近一段时间玩了一下 mcu 编程，也做了一些简单的物联小玩具，分享一下粗略的心得： https://twitter.com/ivarptr/status/1210147205526351872 一共 4 条推，有兴趣的朋友一起交流一下🙈

Blink 程序大概是MCU里的hello world（？）试了几款包括 ATmega 328（Arduino兼容品）, ESP32/8266, stm32 还有 microbit，编程语言有 c, (micro)python, lua, JavaScript，粗略体验一下c比较简单，Py比较好玩（可以直接通过串口即时运行语句），Arduino做小制作比较快速便宜，microbit适合小盆友学。 https://t.co/8ZDUP3XHAr

对于比较偏软件的应用，用 c 或者 python 在 esp 芯片上写程序挺不错的，它内置 wifi，可以直接在 mcu 里实现一些功能，比如联网获取一些数据，然后通过一些墨水屏显示出来或者播放通知声音之类。
