Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.

Building

go build -o goencrypt main.go

Generating Keys

删除Chrome地址栏记录中不需要的网址(访问历史)

Chrome的地址栏自动补齐功能提供了非常方便的地址预测功能浏览器可以通过用户当前输入的字符来与用户的访问历史与书签匹配然后在下拉栏中为用提供准确的补齐方案排名, 提高用户访问效率

在大部分情况下, 这个功能是非常好用的但是有时, 出于某些原因, 用户需要移除某个记录(网址无法访问,网址更换域名等) Chrome提供了组合键Shift+Delete来删除地址栏下拉记录中的某个网址

Install

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

环境 (Environment)
