Quelle catastrophe ce déménagement. Prévu pour le 21 au matin,on nous appelle 5 jours avant pour nous dire que non, finalement ça sera le 22 aprem (avec éventuellement un dédommagement de 60 euros, lol). Le 22 on les attend. 30min avant, ils nous appellent pour dire que ça sera soit à 22h le soir,

A Brown professor gave his students a take-home midterm exam. After suspecting many cheated using AI, he made the final in-person. The orange dots are the midterm scores and the gray dots are the final scores. I applaud S22 for honesty because I would've cheated.

The average life expectancy of a new Russian recruit—from arrival at a training ground to death in a combat zone—lies somewhere between 10 days and three weeks. Once sent onto the battlefield, they survive an average of 20 to 35 minutes. @peterfrankopan.bsky.social foreignpolicy.com/2026/06/25/r...

Like a struggling swimmer, he may take desperate measures to stay afloat.

Students should really realize that coding style is quite unique, and copying another code and changing variable names still results in obvious detections. That includes: *variable name conventions (letter case/camel case/underscores..) *loops (++i/i++/range-based, precomputing bounds/evaluating)

Bon, l'ADEME, comment vous pouvez expliquer la différence de conclusions entre l'usage et l'installation de pompes à chaleur l'hiver vs l'été, fussent-elles air/air réversibles ? A gauche = hiver, à droite = été.

What a strange formula... If you're smart, you can have only 2 ideas per year, but if you're some parasite on big projects with 20 authors where you do almost nothing, you can have 20 per year. Good for people who put their name on all the papers coming from their lab, I guess?

An individual's budget can be spent with 2 1-author submissions. Alternatively, it can be spent on 9 9-author submissions. Other cases interpolate or extrapolate from these, and you can play around with numbers here: www.cs.cmu.edu/~nihars/quot... 3/n

J'ai assisté à une journée d'étude sur l'usage des IA génératives textuelles (GPT etc.) pour les mathématiques, et je pense que ça va changer le métier (sans me prononcer si c'est en bien ou en mal).

Dans le genre "gnagna Chatgpt comprend rien". Je lui ai demandé de me faire une implem C++ du papier suivant : www.sciencedirect.com/science/arti... J'aurais probablement mis des semaines, et il n'y a pas de code en ligne. En 3min il m'a pondu 400 lignes de code. Et ça marche du premier coup.

An algorithm to compute the t-value of a digital net and of its projections

Digital nets are among the most successful methods to construct low-discrepancy point sets for quasi-Monte Carlo integration. Their quality is traditi…

Un truc me gêne pas mal dans la critique de l'IAGen pour l'image. Beaucoup d'artistes se plaignent, à raison, de perdre leur boulot. Cependant, la raison d'être de mon métier de chercheur en informatique graphique est (entre autre) la conception d'outils pour rendre accessible la création digitale.

When dealing with noisy and/or partial inputs to describe a shape, the standard approach in geometry processing is to reconstruct a clean implicit surface first, and to do geometry on it. But why this one in particular? What about all the other surfaces that would have been coherent with the input?
