Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Installing boost on Windows using MinGW-w64 (gcc 64-bit)

Introduction

Boost is easy when you are using headers or pre-compiled binaries for visual studio, but it can be a pain to compile from source on windows, especially when you want the 64-bit version of MinGW to use gcc/g++. This installation process should be thorough enough to simply copy and paste commands, but robust enough to install everything you need.

Note: if you need to install any of the libraries that need dependencies, see this great answer from stack overflow

Get files needed for install

Get the MinGW installer mingw-w64-install.exe from Sourceforge
Get the boost_1_68_0.zip source from Sourceforge
__Note: This should work perfectly w

Step by step guide to run redis-server inside WSL(Windows Subsystem for Linux) on Windows

I have tried to setup redis as starting background task with wsl-autostart, Task Scheduler and with lot vbs scripts including one described here but none of them seemed to work.

In the end I have manually created a simple one that does the job. This script basically starts a hidden Ubuntu Window and starts redis-server inside it.

1. Install WSL (this is tested with Ubuntu 18.04 version)
2. Install redis-server inside WSL sudo apt install redis-server
3. Add sudo permission to your user to execute service command without password

云

• IaaS指提供系统（可以自己选）或者储存空间之类的硬件，软件要自己手动装。PaaS提供语言环境和框架（可以自己选）。SaaS只能使用开发好的软件（卖软件本身，如税务会计、表格文字）。BaaS一般类似于非关系数据库，但各家不通用
• 云服务的特点：零前期成本&按需付费&弹性（类似于租，可随时多加、退掉；但没有残值）、高可用（放在机房中，不同AZ间水电隔离）
