This Veterans Day I want to acknowledge the Black veterans of WWII who fought fascism and nazism and came home to fight for civil rights and democracy here. New research shows Black veterans were critical in securing the voting rights currently under attack.

The most typical car loan went from 3 or 4 years to 6 or 7 over the time car durability approximately doubled.

Perhaps too long: First-owner holding periods are significantly shorter than that. Still, a reasonable expectation that the collateral will be there if there is a default.

Never thought of using classes. As Director of Undergraduate Studies, I had a lonely-hearts advice practice for young men (True rumor circulated that I had married before graduation.) Most common and most obvious advice: "Have you considered asking her out?"
Coupling this, fertility that.

Why don't you academics actually do something about it?!? 😂

This Frenchman has outfrenched every single one of us
A French cyclist survived for three days after a horrendous 130-foot fall into a ravine, kept alive by the bottles of red wine he had in his shopping bag, police said.

Segregation in public accommodations was second class economic citizenship. A dollar in the hands of a Black person did not come with the same rights to spend it that others had. Explore the history of this limited citizenship here: greenbookproject.osu.edu #GreenBookProject #CommunityMap #EconSky

No turning a blind eye, no dismissing it as something less than it is - zero tolerance. Also combat hate by doing the opposite - be a good neighbor, be kind. Honor the memories of those we lost by committing to combating hate and spreading love.

🧵Words matter. We are experiencing a flood of unrestrained antisemitism and hate speech. As a survivor of the Pittsburgh synagogue attack, I know where this leads. We have to stop tolerating and normalizing antisemitism and all forms of bigotry.
Seven years later and my heart continues to ache for the 11 people killed and 6 others injured at Pittsburgh’s Tree of Life Synagogue. They were shot as they prayed for no other reason than because they were Jewish.

May their memories forever be a blessing.

The violent history of segregation and desegregation is a reminder of why safe routes mattered —not just for children— but for adults, too. Contribute your story to this important story. Your story of segregation is history, too.

The Python Software Foundation was recommended for a $1.5M grant from the National Science Foundation. The terms of the award said PSF could not work on DEI, whether or not the grant funding was used for it.

PSF therefore declined the funding.

Science suffers, but commitment to core values remains
TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10/NSF-...

I'm sitting on the university wide social sciences curriculum committee for the first time and curricula review IS exactly the punishment I would wish on my worst enemies
This document is … insane? Incredible?

In it the USG shakes down a university for $1.17 BILLION “to avoid legal action” and dictates how hiring, promotion, admissions, scholarships, and CURRICULA REVIEW will be conducted. It stipulates how and when students can protest on campus.
