A Quick Introduction to Linux Policy Routing 29 May 2013 In this post, I’m going to introduce you to policy routing as implemented in recent versions of Ubuntu Linux (and possibly other Linux distributions as well, but I’ll be using Ubuntu 12.04 LTS)…

1034: Max Area 时间限制: 1 Sec  内存限制: 128 MB 提交: 40  解决: 6 [提交][状态][讨论版] 题目描述 又是这道题,请不要惊讶,也许你已经见过了,那就请你再来做一遍吧.这可是wolf最骄傲的题目哦.在笛卡尔坐标系正半轴(x>=0,y>=0)上有n个点,给出了这些点的横坐标和纵坐标,但麻烦的是这些点的坐标没有配对好,你的任务就是将这n个点的横坐标和纵坐标配对好,使得这n个点与x轴围成的面积最大. 输入 在数据的第一行有一个正整数m,表示有m组测试实例.…

Routing Tables In ASP.NET Web API, a controller is a class that handles HTTP requests. The public methods of the controller are called action methods or simply actions. When the Web API framework receives a request, it routes the request to an action…

[译]Routing in ASP.NET Web API 单击此处查看原文 本文阐述了ASP.NET Web API是如何将HTTP requests路由到controllers的. 如果你对ASP.NET MVC非常的熟悉,那你将感受到Web API routing与MVC routing是非常的相似的.主要的不同点在于Web API选择action的时候,使用的是HTTP method,并非URI path.当然,你也可以在Web API中使用MVC风格的routing.以下,本文将不出现…

●Neutron 的路由服务是由 l3 agent 提供的. 除此之外,l3 agent 通过 iptables 提供 firewall 和 floating ip 服务. l3 agent 需要正确配置才能工作,配置文件为 /etc/neutron/l3_agent.ini,位于控制节点或网络节点上. interface_driver 是最重要的选项,如果 mechanism driver 是 linux bridge,则: interface_driver = neutron.agent.l…
