python openCV 基于TCP的socket网络传输视频（一）

createtime:2019年7月17日我在网上找了好多，现在基本实现了传输视频的功能，其思路是：首先得先了解如何使用openCV采集摄像头数据，其次得了解pythonsocket网络编程。因为socket不能直接传输openCV采集的数据，所以还需要转码操作。在下个版本，我用的类的方式实现了视频传输，这个版本先用平常方法实现的，也是一个客户端，一个服务端。服务端#!/usr/bin/python#-*-coding:utf-8-*-importsock

Ubuntu 9.10总算出来了

这一次Ubuntu的更新可能是因为我正好在家呆着没有工作的原因，感觉等得特别久，平时忙起来更新反而没有怎么注意，呵呵。高兴更新中。因为免费，开源，才能出现这样询问是否升级整个系统的对话框，什么时候，XP，Vista用户能看到MS提供的是否升级整个系统到Windows7的对话框呢？也就是因为免费，开源才能出现像apt-get和新立得这样将软件安装全部一键化的产品，Windows下的迅雷，360等想学但是要完全学会那就不仅仅是技术上的可行性问题了，呵呵，服务器

OpenID 和 OAuth 的区别及第三方登录的安全隐患

不知道什么时候开始，我们已经习惯了点击“用XX帐号登录”或者"LoginwithXX"来访问网站，但是大多数人可能都不知道这背后涉及的事有多复杂。OpenID和OAuth完全是为了两种不同的需求而生OpenID的目标是为了帮助网站确认一个用户的身份OAuth的目标是为了授权第三方在可控范围下访问用户资源OpenID是怎么认证用户的？一个网站如果想要接入OpenID认证是非常简单的，不需要创建应用，不需要AppKey，不需要Secret，只需要将用户导向Op

以一种"廉价"的方式获取页面的标题(downmoon)

有朋友问到：“我需要得到一个webpage的title，因为这个title一般都比较靠前，只要取得html的前面少量内容就可以了。因为要取得很多个页面的title,如果下载整个htmlcode，肯定比较浪费时间。.net好像没有现成的类可以干这件事情(取得部分html)，我应该如何去实现？”一种比较"廉价"(即较小成本条件下)的解决思路：第一步：取出含有页面title部分的最小集合。这是“廉价”的关键！第二步：用正则表达式取出和</title</span>
