The pydev developers insists on using and old ssh repo so they can mine Monero on your gpu with python3, it runs at 54watts to try and hide this. run nvidia-smi to see python3 mining, below the xorg entry.

https://gist.github.com/jaydenkieran/75b2bbc32b5b70c4fdfb161ecdb6daa2 Debian Jessie does not come with the correct Python version out of the box, and instead comes with Python 2. To be able to install Python 3(.5), we have a few options. We could build and install from source, but as per Debian's website, we shouldn't do this. Instead, we will use pyenv, a tool that allows users to switch Python versions easily without breaking their system. seven stars.
