Chciałem opisać koncept pracy nad dużym projektem. Wyobraźmy sobie duży projekt, wiele osób, wiele zakresów biznesowych, wiele osobnych backendów, wszystko powinno być zintegrowane do jednej spójnej aplikacji. Przy takim projekcie proponowałbym pracę w z użyciem projektu BOM (Bill of Materials).

Ten koncept wywodzi się z skomplikowanych projektów ze świata Java.

Poniżej graf przedstawiający taką strukturę.

# You will need latest NVIDIA drivers installed. At the time of writing, version is 331.20. 
# On ubuntu 13.10, it looks like this:
sudo add-apt-repository ppa:xorg-edgers/ppa 
sudo apt-get update 
sudo apt-get install nvidia-331

# Now we need to install bumblebee:
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get install bumblebee bumblebee-nvidia bbswitch-dkms
