Note: This is an old project kept around for sentimental reasons. It might not even build successfully.

An alarm clock for Linux that fscks with your mind. It disregards absolutely every piece of science ever written on waking up effectively but gets the job done. It encrypts a set of files of your choosing, hibernates the computer, wakes it up at the requested time and presents you with a maths problem, accompanied by horrible loud screeching sounds. Upon solving the maths problem your files are unencrypted, while closing the program any other way means they are lost forever.

This is a C++ project utilizing the GTK widget toolkit.

DEPENDENCIES

The following development libraries and their dependencies must be installed on your system for the code to compile:

• gtkmm-3.0
• libcanberra-gtk3
• libcrypto++
• libtar

COMPILING AND RUNNING

From the base directory, run

make
sudo make auth

The pre-hibernation executable (the one you want) is bin/aflaunch. Please ensure that your desktop environment does not present a lock screen/password prompt when waking up from hibernation. Or, if it does but nevertheless plays background audio, just leave it like that, as that is very much in the masochistic spirit of this application.
