Netflix Catalog January update

Took a few  weeks off, first for school, and then for christmas. Back only a few days, and I’ve learned the basics about Cookies and Filters in ASP.NET MVC. They’re both pretty simple, even moreso than I thought. Instead of rewriting a lot of the stuff I read, I’ll just link to the StackOverflow answers that I used directly.

For the cookies, it’s here, where it shows both how to add and delete (via setting the Expiry of the cookie to yesterday) a cookie. I thought that was pretty neat. Basically all it is is a number that the browser stores, and then the server has to do something with that.

Which brings me to Filters, with a SO answer in two parts: Here and the offical docs, which are very surprisingly handy this time. Filters just run before and after certain events, like Authorization, Actions, Results and Exceptions. I’ve only played with “OnResultExecuting” which mean before the ViewResult has been finished being processed, since if I change the ViewBag in the filter, the returned view with contain the modified data.

Other than that, I’ve run into a strange issue which I’m really hoping to solve: the catalog index I got the from Netflix API is incomplete! It’s got about 56k titles on there, individual shows included as separate entries (something I still have to sort out) and I can’t find certain titles, like Dexter and The 4400, which are both available for streaming off I’ve made a post asking for clarification here but looking at the post, it seems like I’ll need to cross post into the “Help me” subforum, rather than the “API forum” forum.

My buddy is still working on the Rotten Tomatoes thing, which has taken a few months now. He hasn’t made much progress as far entering things into the database, but then I realized that without the huge /catalog/titles/streaming resource, I’d probably be in the same spot he is. I’ll have to remind him about the OMDB tool, and how we can just pull the RottenTomatoes data from there instead. Then it’ll be a matter of associating the Netflix movie with the RottenTomatoes movie. That’ll be tricky.

Anyway wanted to make a post here because  it’s been a while, and it doesn’t get any easier to write these. And although I now manage to get about 1000 people to the site a month, I realized 75%+ of them are here for the tutorials I have written. I really should keep working on those… If you ever have something you’d like to learn about, please hit me up!

Latest Project: A new website!

What’s up dudes! It’s been a while, but I’ve been busy. If you’ve been following me on Twitter, you’ll see that I’ve been working on this new website. It’s basically just like or easyqueue or whatever it’s called. I’ve never used them, since I only use it on the xbox, and the interface is pretty bad!

But anyways, the project has been underway for a few weeks now, and while it’s my first website that I’m building from as scratch as you can get with C#’s ASP.NET MVC4, it’s coming along nicely. So far, I’ve managed to pull down the Netflix API’s Index, so that’s about 55k titles that I’ve got to play around with. The dataset is pretty complete, which means that it’s pretty comprehensive.

Once I got MVC4 set up and working, which was not easy, even with sec_goat’s help by the way, was getting a database local server working. I don’t want to get into that too much, because I’m still sick of the idea, but basically MVC4 uses 2012 SQL databases, and I had SQL SERVER 2008, so I needed to update to 2012 to match the server I had created. That meant I needed to update to ’08, ’08 SP1, ’08 R2, ’08 R2 SP1, ’08 R2 SP3, then finally ’12. I think I even needed SP1 on the ’12. But it really isn’t clear the order to me, since at that point I was just installing everything I could and trying to get it to work. It was frustrating.

Another issue I am currently dealing with is the idea of Database Normalization. What that is is essentially splitting up a database in order to get to be the least redundant as it could possibly be. Reducing columns that work out to the same thing. Like say you had an ingredient list, and you added ketchup and mustard and pickles. But EVERY single time you didn’t use ketchup, you took away mustard too, so that means that you might as well have one column called toppings yes or no, rather than a ketchup and a mustard column. Well, that’s actually a really poor example. As usual, Stack Overflow has a better example, as well as actually.

So back to the issue. I used to have ALL the relevant data from the Netflix API in one massive, ugly table, but I wasn’t happy with how long that it was taking to get data from it (and apparently DB Normalization doesn’t really help with that, but maybe it does, I really don’t know at this point) so I endeavored to break it up. So it’s most of the movie data, like year released, duration, rating etc in one table, then a list of all the genres into another, then a cross table, linking one genre to one movie ID. And with Box Art, I’ve got a table of movie id’s linked with the box art of relevant sizes. That way whenever I need to box art for a movie ID, I can just select it from the BoxArt table, rather than look through the whole movies database. Dunno if it helps my speed case at all, but I hope so.

Right this minute, I’m building the list of Movie to Genre table to make. It’s been about 20 minutes since I’ve started writing this, and it’s at movie 909 out of 55k. It’ll take about 10 hours I think to create the table in full, but I’m told that isn’t a terrible amount of time. But again, I don’t know for sure.

So there you have it, good news and bad new. A lot of frustration but a lot of new information, so you take what you can get. I definitely don’t like knowing absolutely nothing about DBM and SQL, and asking really basic questions, but I guess that’s just part of the job. Er, hobby.

Pull out images from a Minus Gallery, using vim.

I was recently told via reddit that it was hard to pull images from as they’ve hidden it behind javascript, and I just took a look to see what I could do, and lo and behold, vim comes to our rescue. In the spirit of Derek Wyatt, I wanted to make a quick tutorial on how to pull those images, in maybe a dozen vim commands.  So just check out that reddit link and enjoy.

Turns a page source into a bunch of valid image links.
