If, like me, your are booting with UEFI (because having a triple boot ubuntu-windows-mac or because UEFI is the most modern type of bootloader and successor of EFI :p), you have to sign the proprietary modules each time they are recompiled (or upgrade kernel version) so that they are allowed to be loaded in the kernel.

1) Step one, create a self-signed certificate to sign nvidia driver:
sudo openssl req -new -x509 -newkey rsa:2048 -keyout UEFI.key -outform DER -out UEFI.der -nodes -days 36500 -subj "/CN=rambou_nvidia/"

2) step two load and store certificate in a supplementary key database MOC 
sudo mokutil --import UEFI.der

3) step three reboot your system
At this step after reboot you will be prompted to select your certificate to import in in key database. If you have inserted a password at certificate creation you'll be prompted to insert it. If you are not prompted, you may have to enter the BIOS by using function keys at boot time.

# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
