An Interactive Visualization of the Netflix Prize Dataset

The visualization activated below (click the button) shows all 17,700 movies that are part of the Netflix Prize Competition. The movies are laid out such that simlar movies are close to one another. Similarity between two movies is computed based on whether users who like one like the other, or (and, really) those who dislike one dislike the other.  Alternatively, take a look at a colorful, static version.

Mouse over to get the movie titles…

PHP on windows is completely possible. If you had bought a domain name from godaddy and they say that you can’t host php on windows, then they are lieing. I suggest you setup your own blog on your own computer. I am writing a step by step on hosting wordpress on IIS & Godaddy. You can check it out at

I too had to install WordPress for a client with a site on GoDaddy (ug!). I called GoDaddy after logging into my client’s account, and he walked me through it step by step. Piece of cake! There is MUCH to be said for live customer-service provided by a human being…after this experience I have a slightly better appreciation for GoDaddy, but their site still makes my eyes cross!!

I put together this guide for installation to make it as simple as possible from start to finish.

The good news is, if you’ve goofed up the first time, you can start from scratch using this guide.

I set up a custom php.ini file in my GoDaddy hosting account, by copying one from a server I own. If you’re familiar with the php.ini settings, or would like to try it out using the settings I chose, go to my web site ( and contact me, and I’ll send it to you. You simply upload the file named php.ini to your hosting root, and in about 24 hours the server will switch over to using it. I have it configured for use with GoDaddy servers, which will allow you to use mailer script.

WordPress on GoDaddy is as simple as can be without changing any files whatsoever. I listened to Ray’s instructions and from my Hosting Control Center, I went clicked on the tab Content. From there I clicked on GoDaddy Hosting Connections which brought me to the GoDaddy Hosting Connection Home. From here, you can either type in wordpress in the search or click on Tools/Scripts (located in the left panel). Under most popular (left panel) you’ll see wordpress at the top of the list. Click wordpress, and it will bring you to an installation screen where you press Install Now. From here, it’s self-explanotory and walks you thru the installation.


Another Visualization of the Netflix Prize Dataset

Here’s a recent visualization I did of the dataset used in the Netflix Prize Competition. The dataset is 17,700 movies and 31 gigs of user ratings. This viz shows similar movies close to one another, with the similarities determined by a formula based on ratings.

I found most interesting a cluster of movies (in blue) that I’d say are generally acclaimed. The cluster contains movies of across all genres, such as Schindler’s List, BraveHeart, and Super Size Me. Beyond that, there’s a bunch of clusters which are mostly defined by a genre such as music, sports, documentary, Imax, children’s films, or bonus material. The big blob in the center is mostly what I’d call junk movies.

I’ve labeled some movies just to give some sense of what the clusters contain. There’s an interactive version of the viz as well, so you can explore the movies for yourself…

In case you have a GoDaddy Windows ASP plan, and like me hit a very high frustration level until you remember this ‘minor’ detail, note that you can easily change your hosting plan to Linux.

In the main GoDaddy site, click on “My Hosting Account,” click on the account name (not “manage account”) and let the page reload. On the right hand side, the gray box will give you an option to”Upgrade/Downgrade Hosting Account”. Click on the link, and when the page reloads, highlight your preferred Linux hosting package. Accept your choice, and wait a few minutes for the new account to activate (your site should not go down while this takes place, mine didn’t).

You will now have an easier time installing Word Press on your own, or alternatively following Ray’s advice (which isn’t available for ASP accounts).

I’ve been uusing WordPress on our Linux/PHP shared hosting account for nearly a year. It was daunting at first but I got the hang of it, and I’m very satisfied with performance and ease of use.

GoDaddy has been excellent value, and I would recommend as a blog host.

I used the auto-install from GoDaddy’s applications, and upgraded later. The new version of WP is really good.

To answer Vet, you can do the URL change in a couple of ways that are easier than moving files.

1. GoDaddy allows an easy way of doing subdomains, and you can point them at your blog directory, giving you a new address.

example: ->

2. You can use a new domain name to point to the directory. Change your domain to something else: Then do ->

We do this with – try and you’ll see.
