Hotlist Snapshots

A repository for snapshots of the KA hot list every two hours.

Inspired by MrMagma's similar project, which was updated for a bit, then broke.

This should record snapshots every two hours (MrMagma's updated once a day).

Ideally, in order to get a good sample size, I would run this for around four months before trying to analyse the data. We'll see how that goes.

###Accessing all the data The easiest way to access the data is by using Rawgit to load allSnapshotData.js as a script tag on your webpage. It will call a allSnapshotData function, which you define, and pass it an object, set up like this: {/*Time snapshot was captured*/ : /*Contensts of the hotlist at that time*/}. For example, the following object might be passed into allSnapshotData:

{
   "Dec_19_11:10:54_UTC_2016" : ({
      "cursor" : "[Some KA String]",
      "snapshots" : [
        {/*Program data like author, title here*/}, {/*Program data like author, title here*/}
      ],
   }),
   "Dec_19_15:10:54_UTC_2016" : ({
      "cursor" : "[Some KA String]",
      "snapshots" : [
        {/*Program data like author, title here*/}, {/*Program data like author, title here*/}
      ],
   }),
   /*etc, but a whole lot more data.*/
}

This is set up the way it is because of how KhanAcademy lets you load external resources.

###Accessing a part of the data The other way to use access the data, if you want to load a smaller sample size, is to load allSnapshots.js as a script tag. This will pass a list of snapshot files to an allSnapshots function, which is up to you to define. You can then use this list of snapshot files to load in the files, also as script tags. They each pass their data to a snaphshot function, again, which you define.

###Examples I made a basic program to give you an idea of how to access the data here on Khan Academy. Edward made a program with this data that does word frequency analysis on the titles of programs. You can find it here.
