The numerical calculus example code from yesterday has been posted to the class git repo (see “Repo” link in the menu bar, above). There are two ways to access it:

1. The best way. Clone the repo to your own system, then browse the files from there. (See Ian’s excellent CPSC 225 notes for instructions on how to clone a repo.) Now, not only do you have a copy of all the files on your laptop, but you also can do a quick “git pull” every time I post an update to the repo this semester, and you’ll automatically suck in the new contents.
2. The sucky way. If you really don’t want to make the effort to clone the repo, github provides a clunky web-based interface you can use to view the current contents of the files: https://github.com/divilian/data420/blob/main/wichita.py. You won’t be able to run them, and you’ll have to manually navigate the repo contents using your browser.
