Llama Land
I wanted to write a sample app to get comfortable with Sinatra, and given that the Hello, World of web frameworks seems to be writing a URL-shortner, I decided to go with the flow.
Llama Land (named from the Sinatra classic Come Fly With Me) is a tiny URL-shortner that fits within 30 lines. Sinatra (the framework, now) is like a little BB gun. It is pretty silly, but you can have fun, and then all of a sudden, you realize that in the right hands, this is a pretty dangerous thing.
I’ve pushed the repository to GitHub. No idea if anyone would find it useful—it’ll probably be comparably fast to write it yourself than fork it—but the code is GPL-licensed.
