最近做的几件事和最近刚读到这篇文章(http://www.jwz.org/doc/worse-is-better.html)让我重新认识了KISS和这个所谓的Worse-is-better原则. 软件是一个相当复杂的系统,哪怕仅仅是一个数百行的程序,也往往在运行时会出现很多不可预知的场景:作为程序员,我们总是想尽可能的保证所有的场景都能得到正确的处理,但这只能是一个美好的愿望:或者这个是类似于一个NP的问题,或者是我们自身能力有限.做超出我们能力的事还想把它做好做完美,那是绝对不可能的.就像俄罗…

本文译自Wikipedia的Performance tuning词条,原词条中的不少链接和扩展内容非常值得一读,翻译过程中暴露了个人工程学思想和英语水平的不足,翻译后的内容也失去很多准确性和丰富性,需要在之后的时间继续细读. Performance Tuning特指计算机系统的性能优化工作.它通常是根据某个现实或潜在的性能问题而发起的.绝大部分系统都会因为负载的升高而导致性能下降,一个系统对于负载的可承受能力称为可扩展性(scalability),调整系统使其可以承受更大的负载就是perform…

一直想试着把自己理解和学习到的右值引用相关的技术细节整理并分享出来,希望能够对感兴趣的朋友提供帮助. 右值引用是C++11标准中新增的一个特性.右值引用允许程序员可以忽略逻辑上不需要的拷贝:而且还可以用来支持实现完美转发的函数.它们都是实现更高效.更健壮的库. move语义 先不展开具体右值引用定义.先说说move语义.右值引用是用来支持move语义的.move语义是指将一个同类型的对象A中的资源(可能是在堆上分配,也可能是一个文件句柄或者其他系统资源)搬移到另一个同类型的对象B中,解除对象A对…

前面讲过一些RabbitMQ的安装和用法,也说了说RabbitMQ在一般的业务场景下如何使用.不知道的可以看我前面的博客,http://www.cnblogs.com/zhangweizhong/category/855479.html 本来一直想写一个介绍RabbitMQ高可用的集群的文章.不过,后来发现园子里,有个已经RabbitMQ大牛写了,关于高可用集群的文章了.特别巧合的是,还是以前公司的同事.所以,这里就不啰嗦.直接引用过来吧.原文地址:http://www.cnblogs.com/…
