This was the most played non-kid song on my playlist last year.
Lauryn Hill releases “The Miseducation of Lauryn Hill” this week in 1998 — making her not only the first hip-hop artist to win a Grammy for Album of the Year but also the first woman since Debbie Gibson to debut at #1 with a song she wrote, recorded and produced on her own.

48 - 50 (not counting airports or drive-bys). I'm pretty sure I have not visited Tucson or Tulsa as an adult, but maybe as a kid. Disappointing that this does not include cities in Alaska or the entire upper half of the country between St Paul and Portland.

In the four-year-old's process of sorting out "real" from "pretend," my favorite part is discovering the fantastical, yet very real, things that she insists are pretend.
This morning's examples are "the Taj Mahal" and "bats."

Grammerly is now telling me to replace all instances of "use" with "utilize."
It used to be pretty good at finding typos, now it is trying to get me to write like a stochastic Internet parrot, I guess.

Does anyone have an accessible guide for best practices in presenting DAGs and associated regression estimates in a paper?
This is for a student thesis project (and, frankly, for myself, as I have done it admittedly ad hoc, although no reviewers have so far complained.)

To reiterate one of my academic themes for 2025: It’s a real problem that students feel incapable of operating without genAI, particularly given that they do worse with it. I don’t care if slackers slack, but if insecurity x manipulation shields well-meaning students from their education, I care.
Every commercial for AI is basically “look, you’re a fucking moron, but we’ll help you fake it!” and it feels like they really do get their target audience.
