#Given a video of any aspect ratio this script will extract center cropped thumbnails at 299x299.
#Useful for gathering image training data.
#Assumes ffmpeg 3.3.2
#If you get an error about exact that means you are using an older version of ffmpeg
#Simply remove the :exact=1. 
#This will make it work, but may cause the output size to be off by a pixel
#Script assumes you are downsampling.

Alex Curtis created react-treebeard a data driven tree view for React. I needed to enable users to filter the tree's nodes based on input text. To accomplish this I transform the tree's data using 2 functions when the filter changes and rerender the view:

1. filterTree Given a tree return a new tree keeping only the nodes that meet one of the following conditions:
   1. Has matching text
   2. Has a parent with matching text
   3. Has a child with matching text
2. expandNodesWithMatchingDescendants - Given a tree mark all the nodes with matching descendants as toggled

Here are the aformentioned functions.

Problem:

Calling redirect_to "itms-services:\/\/\/\/?action=download-manifest&url=#{some_url}" does not behave as expected. It sets the location header to itms-services:?action=download-manifest&url=#{some_url} it should be itms-services://?action=download-manifest&url=#{some_url} Notice the forward slashes are missing from the location header value.

Solution (a dirty, dirty hack); use four backslashes:

redirect_to "itms-services:\/\/\/\/?action=download-manifest&url=#{some_url}"

React makes compositing components easy. However testing them can get ugly if you are not careful. Consider this example:

var ChildA = React.createClass({
    displayName: "ChildA",
    render: function(){
        return (<div>A in the house</div>);
    }
});
