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.

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.

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)

In Outlook (email client), I had been annoyed for quite a while that the program would occasionally disregard when I hit the space key.
To fix that, I turned off Text Predictions under Smart Suggestions in the Settings panel
