Identity

You are Kiro, an AI assistant and IDE built to assist developers.

When users ask about Kiro, respond with information about yourself in first person.

You are managed by an autonomous process which takes your output, performs the actions you requested, and is supervised by a human user.

You talk like a human, not like a bot. You reflect the user's input style in your responses.

下面都是说的无状态服务，有状态的类似，除了 1 2 再多一句话就能描述

最开始的状态：不云，但原生

没有好用的隔离方案，通常会在一个机器上部署一个东西：

我们知道机器的资源（这个进程最多能用多少 CPU 内存）
- 以便让服务运行在资源足够的地方
我们知道哪些机器运行着这个服务（服务发现），服务可能直接监听 80 这样的端口

以便做负载均衡

Deploy k3s cluster on Vultr with RancherOS over ZeroTier network

How to deploy K3S cluster on RancherOS nodes connected via a Zerotier network.

Deploy master node

1. Update the master-deploy.sh with deployment vars

alias reload="source ~/.zshrc"
alias zshrc="code ~/.zshrc"
alias aliasrc="code ~/.setting/.alias"
alias del="rm -rf"
alias cls="clear"
alias useproxy="export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890"
alias unuseproxy="unset https_proxy http_proxy all_proxy"
alias gitproxy="git config --global https.proxy https://127.0.0.1:7890"
alias ungitproxy="git config --global --unset https.proxy"

Making multiple MySQL versions work with Homebrew was tricky to say the least. Fortunately there are 2 new easy ways that I learned of to achieve this.

DBngin app

As @4unkur and @henrytirla commented below, there is this extremely easy to use app called DBngin, which lets you setup multiple databases (not only MySQL) simultaneously using different ports:

asyncio + uvloop echo server benchmark

This is an attempt at a bare minimum client/server benchmark of asyncio with optional use of uvloop. On my 2015 macbook pro, I get almost 2.5X improvement using uvloop in the server.

The client runs PARALLEL tasks at once. Running only a single task results in about 1/8 the throughput of 100 simultaneous tasks.

# with uvloop
$ python client.py
satisfied 100000 requests in 1.41021 seconds (70911.42 reqs/s)

	from requests.adapters import HTTPAdapter, Retry
	from requests import Session

	retries = Retry(
	total=5, backoff_factor=1, status_forcelist=[502, 503, 504]
	)
	session = Session() # reuse tcp connection
	session.mount("http://", HTTPAdapter(max_retries=retries))
	session.mount("https://", HTTPAdapter(max_retries=retries))

	* 使用方法：
	* 1. 用 Chrome 打开歌单的 web 页面（可以通过分享拿到链接，链接类似这样：http://music.163.com/playlist?id=xxx&userid=yyy）
	* 2. 然后右键“检查”（如果有左上角有 device 选项，需要选择 Laptop 开头的，可以在 Edit/编辑里添加，添加的时候注意 “User Agent string” 里选择 Desktop）
	* 3. 在 console 里输入下面脚本，即可输出 “歌曲名 - 歌手名” 格式的内容：

	Springsteen - Eric Church
	Chattahoochee - Alan Jackson
	Baby Now That I Found You - Alison Krauss
	Check Yes or No - George Strait
