Issues students have that we can improve next time

[gaow]

1. Currently a cell in Jupyter notebook can contain multiple lines of codes but sometimes people really want to see the output running one line of code at a time. We should add in the 5 min introduction session how to split one cell into mulple smaller cells. What i do is to create an empty line under the line we want to isolate, then use shortcut ctrl shift - to split a cell into two. Do this multiple times for as many splits as one wants to make
2. Many people complain data cannot befound because they did not cd to the correct folder. I keep telling them to cd then use ls to double check make sure they see the data. Maybe this is something we can add also to the start-up introduction.
3. Demonstrate people how to join the slack channel .... or at least what channel we can find the support team.
4. For long running commands show people how to track it -- for example there should be a "*" next to the command; also when people use htop from the terminal they should see it showing up as a process. We need to tell people how.
