Use nginx as Non-Transparent SSL Proxy

Introduction

Many mobile apps have back-end API servers. They usually rely on the API replies to determine whether certain information is supposed to be shown. If the API responses could be manipulated on the fly, we may easily fool an unmodified app to expose some private data.

This manual guides you to set up nginx as non-transparent SSL proxy, which just subsitutes strings in the server responses (i.e. man-in-the-middle attack ourself). For both server-side (their API servers) and client-side (your device), the whole process is almost transparent.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

1. Take the download.sh file and put it into a directory where you want the files to be saved.
2. cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
3. Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.
