Briefly:
np.dot is the dot product of two matrices.
|A B| . |E F| = |A*E+B*G A*F+B*H|
|C D| |G H| |C*E+D*G C*F+D*H|
Whereas np.multiply does an element-wise multiplication of two matrices.

React components are so fucking stupid, it's unbelievable. 3 months with this library version 15 and the glaring stupidity of the API just keeps coming in waves. Fixing some of this stuff – just for the sake of internal consistency – would have been so simple. The number of hoops you're required to jump through for trivial shit. Ugh.

How effectively delete a git submodule.
To remove a submodule you need to:
- Delete the relevant section from the .gitmodules file.
- Stage the .gitmodules changes git add .gitmodules
- Delete the relevant section from .git/config.
- Run git rm --cached path_to_submodule (no trailing slash).
- Run rm -rf .git/modules/path_to_submodule (no trailing slash).
- Commit git commit -m "Removed submodule "
- Delete the now untracked submodule files rm -rf path_to_submodule
