remade a network diagram in Typst (with the Fletcher package)
If anyone wants to see a demo/walkthrough of Typst, I will be running a casual seminar with the DSLC (Data Science Learning Community) this Saturday at 1 PM EDT!

I updated the syllabus for my Machine Learning course, and I made it---diagrams included---with the Typst Universe!

finished taking an online course in bioinformatics techniques for RNA-Seq. To wrap up, I tried out the tools on a different data set, and then presented the results as a Quarto closeread story!

is happy to be at #useR2025. So far, I ran into 3 colleagues from various ventures, and learned
* how to underline text in Quarto markdown
* that a `countdown` can end with a sound effect
(in addition to a couple of great workshops about tidyomics and srvyr)

Over in Week 2 of our online RNA-Seq course, we learned about normalizing read counts through VST (variance stabilizing transformation). To help me verify the concept for myself, I made a ridgeplot of 10 randomly selected genes in the lung cancer data.

On a whim, I took some of the room icons from the video game Blue Prince and rearranged them to emulate the classic board game Clue

![[Ponytail and Cueball are talking. Ponytail has her hand raised, palm up, towards Cueball.]
Ponytail: Silicate chemistry is second nature to us geochemists, so it's easy to forget that the average person probably only knows the formulas for olivine and one or two feldspars.
Cueball: And quartz, of course.
Ponytail: Of course.
[Caption below the panel]
Even when they're trying to compensate for it, experts in anything wildly overestimate the average person's familiarity with their field.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:wdf3laneizjpmm3l5jvce6vl/bafkreiarxpha556ne5yeezyurqg7bmg2i3rcxpunurfgs3ipdti37b6vta@jpeg)

finished reading Mastering Shiny and had a good semester with a bookclub over at the Data Science Learning Community. Now, whether or not Shiny is one of my new year's resolutions is TBD, haha

finished reading The Programmer's Brain by Felienne Hermans. It is a great book about cognition and learning processes. I have already started using some of the frameworks to ease my students' experiences in learning data science. Thanks to the several of you who have recommended this book.
