remembering the time that I showed to a math class the music video for "Patterns" by Weird Al (to try to get the students out of the "memorize formulas" mindset)
Those college sophomores really didn't like that, haha

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!

Today's joy is finding some rvest code that I wrote over two years ago (and get to reuse!)

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.

found my university's list-serves, which were en vogue about 12 years ago. They are quite a time capsule.

![[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)
