Multiple MySQL Versions for Development

Options included below:

• Using Docker docker-compose
• Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

require 'benchmark'

ITERATIONS = 1000000

def run(array, bench)
  bench.report("#{array.count} keys") do
    ITERATIONS.times { Hash[array] }

Go编码规范指南

##序言

看过很多方面的编码规范, 可能每一家公司都有不同的规范, 这份编码规范是写给我自己的, 同时希望我们公司内部同事也能遵循这个规范来写Go代码.

如果你的代码没有办法找到下面的规范, 那么就遵循标准库的规范, 多阅读标准库的源码, 标准库的代码可以说是我们写代码参考的标杆.

check process mysql
  with pidfile /var/run/mysqld/mysqld.pid
  start program = "/usr/sbin/service mysql start" with timeout 60 seconds
  stop program = "/usr/sbin/service mysql stop" with timeout 60 seconds
  if totalmem > 400 MB for 5 cycles then alert
  if totalmem > 600 MB for 5 cycles then restart
  if cpu > 50% for 5 cycles then alert
  if cpu > 90% for 5 cycles then restart
  if 3 restarts within 5 cycles then timeout
