这是在coursera上面的一门学习pyhton的基础课程,由RICE的四位老师主讲.生动有趣,一共是9周的课程,每一周都会有一个小游戏,经历一遍,对编程会产生很大的兴趣. 所有的程序全部在老师开发的在线平台进行测试,并且还有"VIZ mode",可以通过可视化的模式,理解程序的进程. This class is nine weeks long. For most weeks, you will watch two sets of videos (part a and part b)…

Lock-free programming is a challenge, not just because of the complexity of the task itself, but because of how difficult it can be to penetrate the subject in the first place. I was fortunate in that my first introduction to lock-free (also known as…

老实说笔者学习 Go 的时间并不长,积淀也不深厚,这次因缘巧合,同组的同事以前是上海大学的开源社区推动者之一,同时我们也抱着部分宣传公司和技术分享的意图,更进一步的,也是对所学做一个总结,所以拟定了这次分享.另外与会的同学大多都是大二大三的"萌新",考虑到受众水平和技术分享的性质,所以实际上这次分享涉及到的知识点都相对基础,当然为了寓教于乐,本人也十分讨厌着重介绍基础语法时可能引起的枯燥,所以加了少少的私货,并且也针对 1.11 及之前版本中或优雅,或局限的特性做了发散性的讲解. 总而…

Static and non-Static :  非静态方法(不带static)可以访问静态变量和方法(带static),但是反过来就不行. 类的静态成员(变量和方法)属于类本身,在类加载的时候就会分配内存,可以通过类名直接去访问. 非静态成员(变量和方法)属于类的对象,只有在类的对象产生(创建实例)的时候才会分配内存,然后通过类的对象去访问. 在一个类的静态成员中去访问非静态成员之所以会出错是因为在类的非静态成员不存在的时候静态成员就已经存在了,访问一个内存中不存在的东西会出错. 静态变量和方…

并发编程,在哪个语言里都属于高端应用,一定得会了才好意思说懂了这门语言. 在工作中用得并不是很多,忘了一些内容,就慢慢看,慢慢补上. 今天一天看了近三分之一(我看外文越来越快了??:)), 实践一下多线程的threading模块. #coding: utf-8 import logging, threading from Queue import Queue logger = logging.getLogger() logger.setLevel(logging.DEBUG) formatter…

前言:数据科学越来越火了,网页是数据很大的一个来源.最近很多人问怎么抓网页数据,据我所知,常见的编程语言(C++,java,python)都可以实现抓网页数据,甚至很多统计\计算的语言(R,Matlab)都有可以实现和网站交互的包.本人试过用java,python,R抓网页,感觉语法各有差异,逻辑上是一样的.我准备用python来大概讲讲抓网页是什么概念,具体的内容要自己看手册或者google别人的博客,这里算是抛砖引玉了.水平有限,出现错误或者有更好的办法,欢迎讨论.. more info o…

根据他人的博客,可以发现pip也是可以离线安装已经下载好的包的,具体请参考<pip常用命令>.由于现在还没进展到那个程度,所以本次博客先记录一下我已经学会的东西. 1.pip基本用法 (1)以下载numpy为例,看如何使用pip下载第三方包 只需要打开cmd,然后输入: pip install numpy 如果你的机子现在是联网的,那么就可以下载numpy并且给你安装上. (2)以numpy为例,看如何使用pip卸载第三方包 一样是打开cmd,然后输入: pip uninstall numpy…
