So for the past, oh, year or so, I have been sporadically and half-heartedly working on* a fork of writtenkitten that will let you pull images from more fannishly-oriented sites than flickr, because tbh when you put in "kaiju" or "methos" as your search term it doesn't pull up much from flickr/creative commons.

Anyway, I have gotten as far as rebranding it "wrotegoat", fixing the bug for the first kitten goat, and adding some more user options, but when it comes to actually getting images from Tumblr, I run up against the fact that I have no idea what I'm doing with APIs, and Tumblr makes you "register your application" before you can play with their API.

So if there is anyone here who knows anything about APIs, can you answer me one simple question? To make an app with the tumblr API, I have to register an app. To register an app, I have to have made an app. To make an app I have to register an app. To register an app I have to have made an app. HOW DOES THAT WORK?? Can I register with a dummy URL, keep coding with the files on my hard drive until it at least vaguely works, and then change it later, or something?

...also shouldn't programmers know what an 'infinite loop' is?

*when I know I should be doing other stuff but really really dunwanna
