Social media feeds today are optimized for engagement, often leading to misalignment between users' intentions and technology use.
In a new paper, we introduce Bonsai, a tool to create feeds based on stated preferences, rather than predicted engagement.

Mit anderen Worten: die AfD will ARD, ZDF, Deutschlandfunk, 3sat, Phoenix, Arte und alle öffentlich-rechtlichen Rundfunkprogramme abschaffen. Motto: AfD statt ARD. Der ÖRR war die Antwort auf Goebbels und ist ein Bollwerk gegen rechtsextremistische Wirklichkeitsverdrehung. Gut, dass es den ÖRR gibt

The scientific director of CNRS (France's biggest decentralized research institute) has expressed his insatisfaction with IEEE adding an additional fee for papers made available by authors.
I think all CVF papers will eventually be targeted.

Prompt injection means email viruses are back. A researcher found a security vulnerability where you send an email with hidden instructions which when CoPilot scans the email, executes and then hides the source of the instructions.
It took Microsoft 5 months to fix the issue.

A record increase in atmospheric CO2 according to data released by NOAA gml.noaa.gov/ccgg/trends/..., much higher than projected in the Global Carbon Budget essd.copernicus.org/articles/17/....
This occurred in the presence of an El Niño (red bars, data also from NOAA!).
