<jats:p>I've heard good feedback from my undergrad students about how Jon Sterling publishes his 1A Discrete Maths lectures in a structured online form using his own Forester tool. As my sabbatical comes to an end, I've started prepping my own Foundations of CS course <sup> [1] </sup> for resuming lecturing in October. I ported this course to Jupyter a few years ago along with a nice printable set of notes with the same content.</jats:p>
