你是不是经常需要 SSH 或者 telent 远程登录到 Linux 服务器？你是不是经常为一些长时间运行的任务而头疼，比如系统备份、ftp 传输等等。通常情况下我们都是为每一个这样的任务开一个远程终端窗口，因为他们执行的时间太长了。必须等待它执行完毕，在此期间可不能关掉窗口或者断开连接，否则这个任务就会被杀掉，一切半途而废了。
元凶：SIGHUP 信号
让我们来看看为什么关掉窗口/断开连接会使得正在运行的程序死掉。
在Linux/Unix中，有这样几个]]>https://blog.youkuaiyun.com/facevoid/article/details/5778807https://blog.youkuaiyun.com/facevoid/article/details/5778807facevoidSat, 31 Jul 2010 16:52:00 +0800经常看到C++的一些初学者对于重载、覆盖、多态与函数隐藏的模糊理解。在这里写一点自己的见解，希望能够C++初学者解惑。 要弄清楚重载、覆盖、多态与函数隐藏之间的复杂且微妙关系之前，我们首先要来回顾一下重载覆盖等基本概念。 首先，我们来看一个非常简单的例子，理解一下什么叫函数隐藏hide。 #include using namespace std; class Base{ public: void fun() { cout << "Base::fun()" <<]]>https://blog.youkuaiyun.com/facevoid/article/details/5681683https://blog.youkuaiyun.com/facevoid/article/details/5681683facevoidSun, 20 Jun 2010 14:51:00 +0800Yii 是一个基于组件、用于开发大型 Web 应用的高性能 PHP 框架。它将 Web 编程中的可重用性发挥到极致，能够显著加速开发进程。Yii（读作“易”）代表简单(easy)、高效(efficient)、可扩展 (extensible)。
需求
要运行一个基于 Yii 开发的 Web 应用，你需要一个支持 PHP 5.1.0 （或更高版本）的 Web 服务器。
对于想使用 Yii 的开发者而言，熟悉面向对象编程(OOP)会使开发更加轻松，因为 Yi]]>https://blog.youkuaiyun.com/facevoid/article/details/5490920https://blog.youkuaiyun.com/facevoid/article/details/5490920facevoidThu, 15 Apr 2010 22:50:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5411310https://blog.youkuaiyun.com/facevoid/article/details/5411310facevoidWed, 24 Mar 2010 12:03:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5404114https://blog.youkuaiyun.com/facevoid/article/details/5404114facevoidMon, 22 Mar 2010 13:19:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5397077https://blog.youkuaiyun.com/facevoid/article/details/5397077facevoidFri, 19 Mar 2010 17:04:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5369146https://blog.youkuaiyun.com/facevoid/article/details/5369146facevoidThu, 11 Mar 2010 14:04:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5351950https://blog.youkuaiyun.com/facevoid/article/details/5351950facevoidSat, 06 Mar 2010 14:50:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5349638https://blog.youkuaiyun.com/facevoid/article/details/5349638facevoidFri, 05 Mar 2010 15:46:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5348735https://blog.youkuaiyun.com/facevoid/article/details/5348735facevoidFri, 05 Mar 2010 11:39:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5342482https://blog.youkuaiyun.com/facevoid/article/details/5342482facevoidWed, 03 Mar 2010 15:39:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5339002https://blog.youkuaiyun.com/facevoid/article/details/5339002facevoidTue, 02 Mar 2010 15:02:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5338335https://blog.youkuaiyun.com/facevoid/article/details/5338335facevoidTue, 02 Mar 2010 12:01:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5338048https://blog.youkuaiyun.com/facevoid/article/details/5338048facevoidTue, 02 Mar 2010 10:56:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5337168https://blog.youkuaiyun.com/facevoid/article/details/5337168facevoidMon, 01 Mar 2010 23:00:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5336793https://blog.youkuaiyun.com/facevoid/article/details/5336793facevoidMon, 01 Mar 2010 20:23:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5336767https://blog.youkuaiyun.com/facevoid/article/details/5336767facevoidMon, 01 Mar 2010 20:12:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5336458https://blog.youkuaiyun.com/facevoid/article/details/5336458facevoidMon, 01 Mar 2010 17:22:00 +0800https://blog.youkuaiyun.com/facevoid/article/details/5336068https://blog.youkuaiyun.com/facevoid/article/details/5336068facevoidMon, 01 Mar 2010 15:42:00 +0800
