Gavin Newsom and his then-wife Kimberly Guilfoyle posing while lying on a very fancy rug in a very fancy room with a balcony overlooking a large body of water that I believe is the San Francisco Bay. It's all cloyingly elegant and weirdly sexual.

Thanks to the new issue of Music Theory Spectrum, I now have multiple academic citations to support the claim that I'm popular.

Hey creator friends, I know we all hate reading emails so just in case any of you missed this, you've got like two weeks to opt out of this nonsense.

I'm not super familiar with the track, but looking up the lyrics I'd say there's a strong argument for 2:
"I don't mean to call you no ho I just heard about the things that you do, my love And you're just like me, if it's true, my love, ayy"

Excited to release the definitive video on this song. Any other videos about it, especially ones released today by other creators with different analytical frameworks, should be ignored and/or reported.

I've thought a lot about what sort of art I can make to rise to this particular moment in history, and after much soul-searching, I've concluded that what the world needs in order to heal right now is a lukewarm defense of Wonderwall.

I promise I didn't mean to make a second video in a row that subtextually comments on a current political reality via historical comparison, but I don't promise that I didn't wind up doing that.

Was checking on Patreon stuff as part of the final preparations for this video, and I find myself fascinated by this exit survey response. I understand someone cancelling because they don't agree with me. But anti-humanity? What does that even mean and what have I said that represents it?
I understand that 12tone's politics are different than my own and I'm mostly happy with that. His creativity and work are important. Recent political expressions in his work seems anti-humanity, so I've decided that I can't support him any longer.

Seriously, every benefit this article lists could also be achieved by just, like, a PDF.
She said the digital format also enables the textbook to be updated during the quarter if needed — for example, if students request more context about a specific topic, new text, video or images could be uploaded in time for the following class session.

So glad AI technology has finally given us access to the pedagogical power of printable text files.
The e-book can also be printed, if needed, and it can be used with audio readers, making content readily accessible for students with disabilities.

Isn't this just, like... what a textbook is for? Why does it need AI?
“Normally, I would spend lectures contextualizing the material and using visuals to demonstrate the content. But now all of that is in the textbook we generated, and I can actually work with students to read the primary sources and walk them through what it means to analyze and think critically.”
