Network

Why do you need to place your servers geographically close to your users? One of the reasons is to achieve lower latencies. That makes a lot of sense when you are sending short bursts of data that should be delivered as quickly as possible. But what about large files, such as videos? Surely there is a latency penalty for receiving the first byte, but shouldn’t it be smooth sailing after that?

IPv4 vs IPv6... Why do we need to transition from the Internet Protocol that's served us so well for all these years? Maybe because we're completely running out of IP addresses!

按照这个 https://serversforhackers.com/c/tcp-load-balancing-with-nginx-ssl-pass-thru 配置tcp流量的应该没问题

HTTP 协议（Hypertext Transfer Protocol）已经成为互联网上最常用的应用层协议，然而其本身只是用于传输超文本的网络协议，不会提供任何安全上的保证，使用明文在互联网上传输数据包使得窃听和中间人攻击成为可能，通过 HTTP 传输密码其实与在互联网上裸奔也差不多。

看到刚讨论wifi6，正好我们播客昨天发了一个对wifi6的小节目：https://dao.fm/2020/02/14/vol-202-%e7%a7%91%e6%8a%80%e9%b2%9c%e5%a3%b0%ef%bc%9awi-fi-6-%e5%88%b0%e5%ba%95%e6%98%af%e4%bb%80%e4%b9%88%ef%bc%9f/

这个不是很清楚。正在看 https://martinfowler.com/eaaDev/EventSourcing.html 刚好提到 Event Replay，Event Replay: If we find a past event was incorrect, we can compute the consequences by reversing it and later events and then replaying the new event and later events. (Or indeed by throwing away the application state and replaying all events with the correct event in sequence.) The same technique can handle events received in the wrong sequence - a common problem with systems that communicate with asynchronous messaging.

为什么这么设计（Why’s THE Design）是一系列关于计算机领域中程序设计决策的文章，我们在这个系列的每一篇文章中都会提出一个具体的问题并从不同的角度讨论这种设计的优缺点、对具体实现造成的影响。

HTTP/3 is the next protocol for network communication across the Web, which is meant to partially replace HTTP/1 and HTTP/2. One month before the next QUIC Working Group meeting, to be held in Zurich next February, it may be useful to recap what HTTP/3 promises and what its current client/server support looks like.
