What Is VC? Use software tools to keep a running record of 1 or more files. Why You Should Use VC? ● Lets you revert to earlier versions of your work ● Provides a record of what changed when ● Lets you mark significant points in time ● Allows you to play "what-if?" ● Facilitates organized collaboration (with your future self, as well as with other people)
What You Should Use VC For ● Model Code ● Python, R, Matlab, etc. Scripts ● Plotting Scripts ● Processed Data Files & Scripts That Made Them ● Complicated Marking Spreadsheets (especially if shared) ● Thesis ● Papers ● ToDo List ● ...
