I keep a journal using the Day One app for macOS/iOS, and while I have some lingering concerns about platformizing (and even digitizing) my journaling, there are also some pretty neat aspects to using an app like this. First, it’s very easy to copy text from other electronic sources into the app, and that really helps me capture things that made an impression on me from day to day. Second, it’s also easy to search for, read, and even be reminded of old entries.

One of the most interesting parts of teaching information communication technology classes despite not being formally trained in that field is picking up terms and concepts that I never learned as part of my degrees. One of the most interesting concepts I’ve picked up along the way is the formal distinction between digital and analog phenomena. I often use clocks or thermometers as examples of this in class: Analog phenomena can take on any number of values within certain bounds, whereas digital phenomena are limited to discrete values within those bounds.
