Getting Set Up With Wakari and JITCode

Navigate to to get started with Wakari.

Once you've logged in, you should go into the settings menu, and under "account settings" change your password from the default one, to something more convenient from you. As soon as you save your settings, return to your user page and open up the JITCode project. Once in the project, you will have the option to open up an iPython notebook, viewer, or terminal, among others. Click the iPython notebook option and then click the first lesson to get started.

Before we start, know that this problem take an inordinate amount of time, and I will be glossing over a lot of my process in solving this. I will hit the highlights, but as with many things like this, practice makes perfect. Lets see what they give us.

This program seems to be rather delightfully twisted! Can you get it to accept a password? We need it to get access to some Daedalus Corp files.

And the hint,

>This program appears to be "packed." Fortunately, it's packed with a common packer, and no trickery was performed - so you should be able to just unpack it with the same packer.

file = fs.readFileSync(process.argv[2] || "schema.laml").toString()
