How to:

Fix pseudo-streaming videos by moving Moov Atom

Relies on some *nix CLI utilities: mediainfo; and qt-faststart (part of ffmpeg). I used homebrew to install them on OS X.

What is pseudo-streaming?

Pseudo streaming is simply a video that can start playing before it's fully dowmloaded. The videos are not streaming but rather progressively downloaded. What's important is that the file metadata (the Moov Atom) is at the start of the file rather than at the end. Usually this is an option set when encoding the file (called quick start or web start). If the files have not been encoded this way you can either re-encode or use a utility to move the Moov Atom. Re-encoding takes much longer than using a utility to move the Moov Atom so here's how to do it.

Steps

First check with mediainfo to see if video 'is streamable':

// 坑一、js的基本类型有那些？
    number  string boolean object null  undefined  
    
    typeof null   //===>"object" 
    
    //这只能说是最初的JavaScript实现的bug,而现在标准就是这样规范的.
    //V8曾经修正并实现过typeof null=== "null",但最终证明不可行.http://wiki.ecmascript.org/doku.php?id=harmony:typeof_null 
// 坑二、NaN  isNaN
    isNaN('a')   //===>true
    isNaN('09')  //===>false

Scrum

什么是Scrum？

• Scrum是一种迭代式增量软件开发过程，通常用于敏捷软件开发。Scrum在英语里是橄榄球运动中争球的意思，强调迅速，自我管理和可适应性。 虽然Scrum是为管理软件开发项目而开发的，它同样可以用于运行软件维护团队，或者作为计划管理方法。

谁会用到Scrum？

• 产品经理
• 项目经理
• 开发人员
• 测试人员

1) Generate RSA key:

$ openssl genrsa -out key.pem 1024
$ openssl rsa -in key.pem -text -noout
2) Save public key in pub.pem file:

$ openssl rsa -in key.pem -pubout -out pub.pem
$ openssl rsa -in pub.pem -pubin -text -noout
3) Encrypt some data:
