Tomorrow, I'll have three minutes at a faculty discussion session to explain why I'm so committedly against AI. Should be fun.

Universities across the world seeing this:

"its only wrong 45% of the time!!
Lets buy free licenses for our students, staff and faculty!!
Lets lock into contracts with rapacious predatory AI companies with shitty technofascist politics, sucking up water and jacking up electricity prices!!"

gfd it people, don't obviously use LLMs to write _academic papers_. What is wrong with y'all that you do not understand how that's a dumb fucking thing to do?

The entire-ass point of academic papers is for you to tell me what you think. If I wanted to know what an LLM thinks, I WOULD ASK IT MYSELF.

This whole section really.
Finally: AI cannot do your job, but an AI salesman can 100% convince your boss to fire you and replace you with an AI that can't do your job, and when the bubble bursts, the money-hemorrhaging "foundation models" will be shut off and we'll lose the AI that can't do your job, and you will be long gone, retrained or retired or "discouraged" and out of the labor market, and no one will do your job. AI is the asbestos we are shoveling into the walls of our society and our descendants will be digging it out for generations:

Complètement espanté par la modernité de ces représentations graphiques du mouvement des planètes autour du soleil en fonction du temps. La plus ancienne est de Bède le vénérable (début du VIIIe siècle) et on les trouve dans divers manuscrits de l'époque carolingienne et des XI/XIIe siècles
Varia de Computo Xe siècle, Limoges Ms Latin 5239, folio 39 r. from the medieval encyclopedia Liber floridus ("Book of flowers'), completed in 1121, represents the movements of the Sun, the Moon, and the five known planets through the sky over time. Although it draws on a graphical tradition dating back to Pliny the Elder, the diagram's style and detail break new ground, evoking a modern infographic. Indeed, the display of celestial information here is remarkably similar to the kinds of charts used by today's skygazers. University Library, Ghent/CC BY-NC-SA 2.0 BE Diagram of planets’ orbits, from a scientific miscellany, France or England, late 11th or 12th century, Royal MS 13 A XI, f. 143v The diagram in a scientific miscellany made in the late 11th or early 12th century takes yet another approach, mapping planets’ orbits onto a sort of graph. The sun’s regular appearance in the sky here contrasts with the other planets’ (and the moon's) more variable appearances over days, months and years. Manuscrit 347 Burgerbibliothek, Bern Parchemin 41 ff. 24-24.5 x 22.5-23 cm deuxième moitié du IXe siècle

Victoire inattendue en commission spéciale ce lundi, mon amendement pour supprimer l'HCERES vient d'être voté !

Dans quelques jours en séance, ce pourrait être la fin de cette instance bureaucratique inutile qui parasite le bon fonctionnement de la science et pousse à la compétition !

Using AI to produce writing or art is like asking someone at the gym to lift weights for you.

The effort is the point.

I really love free little websites with a single, useful tool - what are your favourites?

I use symbolsalad.com basically every week. It has a huge number of unicode symbols that you can copy, including Greek letters and absolutely loads of math symbols.
A screenshot of symbolsalad.com. The webpage is quite plain and white. It has buttons for lots of different symbols, like superscript/subscript numbers, Greek letters, and math symbols.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography
This image shows the hourglass shape of the nights shortening and lengthening from winter to summer and from summer to winter, passing clouds, the Moon passing through the night sky every month (diagonal bands) and the Sun climbing higher in the sky during summer.

Dear academics

We could dramatically reduce our administrative workload if we all just agreed not to ask for reference letters until we made our list of finalists.

This is massive collective action problem has already been solved by…

…every other industry on earth.

Who is for abolishing grad app letters of rec at the point of application? Would it be so bad if letters were requested AFTER candidates were shortlisted? If we do this at UCSD who will join us?

A favorite recent project: Peakscapes. I love the layered looks you get in the #mountains, and I always want to be able to name everything in view. These designs provide a cleaner, more idealized view of the landscape than a photo can.

Are they #maps? Or geographic art? I'm not sure.

Ice clouds are seen over the surface of Mars on the upper right. Toward the lower left is a bright spot in the sky which is likely the Sun setting through Martian dust. Please see the explanation for more detailed information.

Visualization researchers work with domain experts all the time. Through many collaborations, I've noticed how crucial it is to align expectations from the start. Here I share insights on what makes an effective partnership. What's your experience here?

There is no obvious picture. There is just a background with a single color. This color, a type of off-white or beige, is called cosmic latte. Please see the explanation for more detailed information.
