If you assure me this will mean that bike lanes are swept more than once a month, people are fined for putting leaf piles in bike lanes, and cops are fired for parking in bike lanes, I’m in.

Today, something happened in the City of Sacramento. The beginning of something exciting. Language was filed with the city for a ballot measure to raise sales tax 0.5% to fund safe streets and transit infrastructure. It's gonna take everyone to get this passed, but together, I think we can do it. 🚲🚌

I, more than most, get that sports is actually a way to get some non-college grads to care about the institution. But I think we have to start thinking deeply about what a university is, given that accreditation is months away from fully breaking

One of the greatest punk rock bands of all time, fractured and irreconcilable 🀬 πŸ’”

40 years ago today,
The Dead Kennedys played their last concert with Jello Biafra at UC Davis' Freeborn Hall, February 21, 1986

Phranc, Mojo Nixon, and 7 Seconds were the support acts

NBC ran a piece where Mary Carrillo went to Norway to find out why they're so good at the Winter Olympics and i was yelling BECAUSE IT'S COLD THERE

then she went to a little tiny ski jump for kids and was like "it's free, equipment is provided, & they don't emphasize results"

and i was like.

European Parliament Votes Overwhelmingly For "The Full Recognition Of Trans Women As Women" The resolution, though nonbinding, is a significant shot at those who seek to erode transgender rights on the continent.

In incredible news, the European Parliament has voted overwhelmingly for "The Full Recognition Of Trans Women As Women."

Even the center-right European People's Party voted for the declaration.

It will form a foundation for their position at the UN Commission on the Status of Women.

Our latest.

WATCH: Trump, EPA's Zeldin announce end of scientific basis for U.S. action on climate change The Trump administration on Thursday revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the most aggressiv...

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate changeβ€”all so the fossil fuel industry can make even more money.

If Bad Bunny can cover the history of Puerto Rico, colonialism, transatlantic slavery, hemispheric consciousness, as well as contemporary life and politics in under 14 minutes, you can do your 15- or 20-minute conference presentation with time to spare.

Why are we giving anything to a company that says they are pivoting away from EVs to robots? Why not invest in a company in it for the long haul?

This isn't mine, and I can't definitively find the original source. But I love this little bit of wisdom:

"If you're a fifteen-minute walk from a coffee shop, but the server there has to drive an hour to get to work, you don't live in a walkable city. You live in a theme park."

For any elected official who needs to hear this, I impart a lesson learned from the NFL:

When the other team is tired and on the back foot, you don’t call a timeout so they can catch their breath. You grind their fucking face into the dirt until the final whistle blows and you’ve won the game.

It could take a generation to recover the talent lost from federal science.

But it doesn't have to. We should be ready to scale up the Presidential Management Fellowship program to triple what it once was and rebuild U.S. capacity by 2030.
