App Framework Explained
App FrameWork是基于HTML5重写的jQuery框架，对其进行了简化，更有利于在移动设备上应用，并且速度比较流畅。
App FrameWork框架页面基本都在同一个HTML文档中，在内容区(#content)里面放置多个class为"panel"的p， 这里每个p即为一个页面。当panel设置selected="true"属性后，在应用打开之后默认加载该页面，其他都是隐藏的(display:none)。这些页面之间通过锚链接来跳转，并将目标页面的display设置为"block"，同时给需要隐藏的页面一个向左移动的动画，加之panel页面使用绝对定位，宽度高度均铺满content，这样的跳转就达到了native应用页面切换的效果。在页面切换时，另外的动作就是将panel页面中已经定义的title属性中的值显示到导航中，并可以设置属性data-tab的值来选中对应的标签。

快速排序Quicksort演示
日本程序员norahiko，写了一个排序算法的动画演示，非常有趣。排序算法（Sorting algorithm）是计算机科学最古老、最基本的课题之一。要想成为合格的程序员，就必须理解和掌握各种排序算法。
目前，最常见的排序算法大概有七八种，其中"快速排序"（Quicksort）使用得最广泛，速度也较快。它是图灵奖得主C. A. R. Hoare（1934--）于1960时提出来的
