Gitlab from source + viewing ipython notebooks

This is what I needed to complete Gitlab installation by using @martijnvermaat's fork. Some guidelines are provided here. This is supposed to allow you to use a local installation of gitlab capable of rendering Ipython Notebooks. This was based on GitLab's documentation.

Pre-installation

But it won't mount as serial port:

Pwn2Win CTF 2016: Timekeeper's Lock

This is the challenge.

In order to protect their maximum security facilities, the Club employs an electronic security lock activated by a 256-bit key which changes every minute. When a Club member is authorized to enter some of these facilities, he receives this key in hexadecimal format, the same format which is used to enter the key in the electronic lock’s keyboard. The last year (in 2015),
