捕捉浏览器中的JS运行时错误，主要通过监听window.onerror来实现。但是对于不同的脚本执行方式以及不同的浏览器，能捕获到的信息会有区别。

window.onerror 讲接收3个参数：

• msg：错误描述，比如：a is not defined
• url：出错脚本所在的url
• lineNumber：出错脚本的行数

本文将对不同浏览器和不同的脚本执行方式进行测试，并总结这些区别。

Setup new Mac with OSX Lion from scratch

Latest update 20-Oct-2012. me@jjperezaguinaga.com

Install Command Line Tools for Xcode

Command Line Tools are required for Homebrew. Previously it was suggested to download Xcode 4, but since the new version doesn't ship the proper gcc compiler for rvm, the command line tools are a better option and then using homebrew to get the gcc compiler. If preferred, install Xcode 4, although this setup doesn't follow that set of instructions.

Really the nicest choice for a terminal on OSX right now, especially with Lion style full screen support.

python项目通用组件和基础服务

很多公司都大量使用了python，其中有一些开发规范，code guidline， 通用组件，基础框架是可以共用的。

每个公司都自己搞一套, 太浪费人力，我想开一帖和大家讨论一下这些python基础设施的搭建。

原则是我们尽量不重新发明轮子，但开源组件这么多，也要有个挑选的过程和组合使用的过程，在这里讨论一下。

另一方面，有些开源组件虽然强大，但我们不能完全的驾驭它，或只使用其中很少的一部分，我们就可以考虑用python实现一个简单的轮子，可控性更强，最好不要超过300行代码。

var arr = [1,2,3,4,5,6,7,8,9];

arr.reduce(function(prev, cur, i, index){
  // 奇葩
  console.log(prev,cur,i,index, arr[--i] === prev)
})

arr.reduce(function(prev, cur, i, index){
  // 正常
  console.log(prev,cur,i,index, arr[--i] === prev)

// 大家写在评论中吧，代码高亮可以这样写：
// ```js
