In the name of protecting Jews, Jews have their funding cancelled, get kicked out of seminars, and are removed from leadership positions in Jewish Studies to be replaced by non-Jews.

Hey 👋🏽 Cville peeps! If you haven't voted yet, be sure to get out on TUESDAY, NOVEMBER 4 to vote. Voting is, admittedly, a rather limited way to build political power, but it's still a really important one.

Here's the sample ballot for Cville. Next up, I'll share who I'm voting for, and why

Federal Judges— or staff, but same-same— used "AI" to summarize & draft rulings, issued them w/o checking the work, leading to basic factual errors, & thus undermining the facticity & validity of the rulings entire.

Gee. Who Could Have Foreseen. *stares directly into the camera like in the office*
Two federal judges say use of AI led to errors in US court rulings
Two federal judges admitted in response to an inquiry by U.S. Senate Judiciary Committee Chairman Chuck Grassley that members of their staff used artificial intelligence to help prepare recent court orders that Grassley called "error-ridden."

I wouldn't have believed it unless I saw it with my own eyes, but apparently it's still possible for experienced financial journalists to write long-ish articles about exploding home insurance prices and never mention the phrase "climate change."

Whenever I cite studies showing bike lanes don’t hurt (and often boost) local business, someone says, “Yeah, but those are from the big cities so don't apply here”

So here’s a quick note on why small towns can be surprisingly dense and why big-city lessons still apply.

Good bike infrastructure will make the Charlottesville area a better and safer place to live. We are tired of waiting for it to become a reality. It’s not that hard. We need the city to deliver on its promises asap.
“When streets became calmer & safer, more people felt comfortable trying a bike commute for the first time. Families began pedaling to the park…Local businesses saw new life…And cycling stopped feeling like a niche activity—it became part of everyday Parisian life.”
