This will be a one day course on useful tools to work with NOSG on shielding and optics. Version control and change management feature heavily here. Potential topics are git, mercurial, meld, python, confluence, and JIRA. A rather boring, but important step, will be setting up the software on the users machines, and setting up the accounts for those who do not have them, hence a full day. Any spare time later in the day can be made profitable by face to face collaboration with NOSG experts.
