FWIW: I'm not the author of the content presented here (which is an outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
Whoo! This was a fun challenge with loads to learn. :)
The given code level11.c checks whether the two inputs (as argv[1] and argv[2]) both MD5 hash to the same value or not. If they do, it uses both inputs as brainfuck code, and executes them. Then it checks if the outputs differ. Upon differing outputs, they are checked against the strings "io.sts Rules!" and "io.sts Sucks!". If prog1's output is the first, and prog2's output is the second, we are granted shell.
Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.
In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.
Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j
