If someone refers an undergraduate student to a known sex offender for a job, and includes a comment about how good-looking the student is in their recommendation letter, that someone should never be allowed to teach undergraduate students ever again.

(FYI it seems like they no longer appear "by default" over abstracts, at least in the cases I've tested)

Screenshot of a paper entry:
Fictional Failures and Real-World Lessons: Ethical Speculation Through Design Fiction on Emotional Support Conversational AI

(There are tabs with "abstract" and "summary" and "summary" is selected.)

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

Writing code on a bumpy train and tried stabilizing the display image to my head -- it does (surprisingly) make things a bit easier to read but overall feels too weird to actually use.

A drawing of two clusters one cluster has a blonde girl with a ponytail in it, and the other cluster has a redhead a blonde and a brunette. This represents the scene and mean girls where Gretchen tells Regina George “you can’t sit with us!”

How can one reconstruct the complete 3D interior of a wood block using only photos of its surfaces? 🪵
At SIGGRAPH'25 (Thursday!), Maria Larsson will present *Mokume*: a dataset of 190 diverse wood samples and a pipeline that solves this inverse texturing challenge. 🧵👇

From the googlemapsshenanigans community on Reddit: The moderators of Internet Roadtrip somehow placed this marker at Inkerman, New Brunswick, Canada, and used it to teleport to Denver and back. Explore this post and more from the googlemapsshenanigans community

These appear to be constructed "wormholes", to go by www.reddit.com/r/googlemaps... . There's a technique to create them, but one person wrote, "I didn’t want the technique to be publicly known and easily accessible, as it is (though minor) a kind of google streetview vandalism."

Internet Roadtrip Let's take a streetview roadtrip

The Internet Roadtrip is now trying to cross Labrador. A 100-foot gap in Street View coverage almost forced them to turn back, but as they approached the break, someone got a friend in Labrador City to drive to the spot IRL and take and upload a panoramic photo to fix it. neal.fun/internet-roa...

Asking the OpenAI Whisper audio model to transcribe 30 seconds of silence generates the output "ترجمة نانسي قنقر", which is "translation by Nancy Qanqar".

Nancy Qanqar is a volunteer translator of (among other things) many pirated movies, so that invites an interesting conclusion on data sources.
