Build libcurl for android NDK

Libcurl requires openssl and zlib to be fully operationnal

Step 1 : cross compile zlib
Step 2 : cross compile openssl
Step 3 : cross compile curl with zlib/openssl external link

Prerequisites :

Docker Hub 镜像加速器

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

1️⃣ Docker daemon 配置代理（推荐）

参考 Docker daemon 配置代理

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、表格文字处理）。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）

其他人的集合

https://education.github.com/pack GitHub学生包，需用教育邮箱验证。各种福利，可从DigitalOcean上手

How to disable systemd-resolved in Ubuntu

Stages

Disable and stop the systemd-resolved service:

  sudo systemctl disable systemd-resolved.service
  sudo systemctl stop systemd-resolved

Then put the following line in the [main] section of your /etc/NetworkManager/NetworkManager.conf:
