The slides are licensed under These lecture materials are licensed under CC BY-SA 4.0 (license deed)., which means that if you adapt the material: meaning that you remix, transform, or build upon it, you must mark your adaptations and share the adapted version under the same license.
This does not mean that merely using one of my slides or assignments requires that you must license your whole presentation under CC BY-SA. Only if you were improving the presentation itself, such as by fixing errors, or adding new slides that were meant to go before or after other slides in these decks, would I expect the specific modifications or improvements to be licensed under CC BY-SA.
My main intention behind using a share-alike license is to ensure that I can incorporate error fixes, better explanations, and better diagrams in these materials, without violating a more restrictive copyright imposed by the adapter.
The code samples are MIT license, and therefore do not require share-alike.
When citing a slide, please mention the specific file you got the slide or assignment from, with a link to that file, along with my name: Grant Williams (or other copyright holder if the slide is marked with a distinct copyright), and the license CC BY-SA 4.0, with a link to the license deed or text.
