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）；BaaS一般类似于非关系数据库，但各家不通用，有时还有一些其它东西。

My Elasticsearch cheatsheet with example usage via rest api (still a work-in-progress)
| The primary goal is to swap command and option. | |
| The secondary goal is to remap Caps Lock to Control. | |
| The tertiary goal is to share modifier keys across keyboards, so you can emacs with two keyboards. | |
| The following instructions are good as of 2016-08-24, for OS X El Capitan 10.11.6. | |
| Mac OS Sierra broke Seil support; Seil instructs us to consider Karabiner Elements. | |
| But when Karabiner Elements swaps command and option, it does it for all keyboards; | |
| meaning the native keyboard also gets its command and option swapped, which is bad! |

| good, 你已经有了一个自己的shadowsocks代理了，现在想要把这个代理公布出去给所有人分享。 | |
| 但是没有两个小时，代理就没法使用了，为什么？因为你需要额外注意以下事项（以下步骤需要比较高的linux技能） | |
| 本文只关注于确保shadowsocks服务还“活着”，如果你希望让其跑得更快，请参考 | |
| https://github.com/clowwindy/shadowsocks/wiki/Optimizing-Shadowsocks | |
| 1、 shadowsocks的timeout设置 | |
| 超时时间越长，连接被保持得也就越长，导致并发的tcp的连接数也就越多。对于公共代理，这个值应该调整得小一些。推荐60秒。 | |
| 2、 检查操作系统的各种限制 | |
| 对于openvz的vps，特别需要检查一下 |
| # Config for Nginx to act as a front-end for Riak | |
| # The main goal is to proxy all GETs directly to Riak, and disallow anything else (POST, PUT, etc) | |
| # Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_) | |
| # Config is in /etc/nginx/sites-available/default or somewhere like that | |
| # Set up load-balancing to send requests to all nodes in the Riak cluster | |
| # Replace these IPs/ports with the locations of your Riak nodes | |
| upstream riak_hosts { | |
