摘要： Python标准库05 存储对象 (pickle包，cPickle包)作者：Vamei 出处：http://www.cnblogs.com/vamei 欢迎转载，也请保留这段声明。谢谢！谢谢reverland纠错在之前对Python对象的介绍中 (面向对象的基本概念，面向对象的进一步拓展)，我提到过Python“一切皆对象”的哲学，在Python中，无论是变量还是函数，都是一个对象。当Python运行时，对象存储在内存中，随时等待系统的调用。然而，内存里的数据会随着计算机关机和消失，如何将对象保存到文件，并储存在硬盘上呢？计算机的内存中存储的是二进制的序列 (当然，在Linux眼中，是文本流) 阅读全文

摘要： http://blog.csdn.net/yao_qinwei/article/details/7578924在我们实际的开发过程中，我们当前这样定位前端、后端开发人员。1）前端开发人员：精通JS，能熟练应用JQuery，懂CSS，能熟练运用这些知识，进行交互效果的开发。2）后端开发人员：会写Java代码，会写SQL语句，能做简单的数据库设计，会Spring和iBatis，懂一些设计模式等。现在来看，我们对前后端的要求还是蛮低的，尤其是后端，新员工经过培训之后都是可以参与到后端开发的，没有太高的技术门槛，唯一需要做的就是先变成熟练工种，这个阶段没有涉及到设计模式、架构、效率等一些列问题。还是先 阅读全文

摘要： 来源：http://blog.csdn.net/clever101决心学习Makefile，一方面是为了解决编译开源代码时需要跨编译平台的问题（发现一些开源代码已经在使用VS2010开发，但我还没安装VS2010，我想在VS2008下编译这些代码）；另一方面源码在服务器端编译的话，使用IDE的方式编译还是不太方便。本文主要分为三部分：第一部分讲述namke工具使用makefile的用法；第二部分讲述makefile的主要语法；第三部分讲述自己动手实践学习写makefile文件。第四部分是编写一个工具将vc工程文件转化为Makefile文件。首先要清楚的是在VS环境下使用Makefile的工具是 阅读全文
