Raspberry Pi - set static IP address

Set a static IP address on a Raspberry Pi 2 so I can connect to the same address all the time using Putty on Windows.

Editing /etc/network/interfaces seems to no longer work.

One needs to edit /etc/dhcpcd.conf

Install Pycharm on Ubuntu

Download gz file from http://www.jetbrains.com/pycharm/download/

INSTALLATION INSTRUCTIONS

• Copy the pycharm-*.tar.gz to the desired installation location
  (make sure you have rw permissions for that directory)
• Unpack the pycharm-*.tar.gz using the following command:
  tar xfz pycharm-*.tar.gz
• Remove the pycharm-*.tar.gz to save disk space (optional)
• Run pycharm.sh from the bin subdirectory

NOTE: PyCharm on Linux doesn't need special installation or running any installation script. It runs out of the pycharm-*.tar.gz
