Intro

This is a basic collection of things I do when setting up a new headless ubuntu machine as a webserver. Following the steps below should give you a reasonable secure server with HTTP/2 support (including ALPN in chrome) and the fast NGINX server. I am happy to add things so leave a comment.

Basics

After creating the server (droplet on DigitalOcean) log in with

    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;

File locations:

• nginx.conf to /usr/local/etc/nginx/
• default.conf and default-ssl.conf to /usr/local/etc/nginx/sites-available

Tinder API documentation

http://rsty.org/

I've sniffed most of the Tinder API to see how it works. You can use this to create bots (etc) very trivially. Some example python bot code is here -> https://gist.github.com/rtt/5a2e0cfa638c938cca59 (horribly quick and dirty, you've been warned!)

Note: this was written in April/May 2014 and the API may have changed since

/**
 Provides the ability to verify key paths at compile time.
 
 If "keyPath" does not exist, a compile-time error will be generated.
 
 Example:
    // Verifies "isFinished" exists on "operation".
    NSString *key = SQKeyPath(operation, isFinished);
 
    // Verifies "isFinished" exists on self.
