Installing new packages behind proxy

There are 2 main ways to do this :

pip install pandas
python -m pip install pandas --proxy proxy..com:3128

Second option has many other parameters which can be passed.

For installing via notebook, we can do as follows :

import sys
!{sys.executable} -m pip install numpy

!{sys.executable} -m pip list --user 

Converting screen into tmux ( terminal multiplexer )

We have beutiful program called
tmux
which allows us to see multiple terminal windows at the same time. We can covert screen in doing something similar.

To split vertically: ctrl + a then |.
To split horizontally: ctrl + a then S (uppercase 's').
To unsplit: ctrl + a then Q (uppercase 'q').
To switch from one to the other: ctrl + a then tab

We can save layouts in screenrc so that we wont have to keep doing this as well.
