1. The name of the highest peak in suburban Atlanta is notable in its relation to the name of Major League Baseball's controversial first Commissioner. What is that peak's name?

Cripes. This houses the 91-cm refractor, nearly 140 years old. I hope the damage to the dome and telescope isn't as severe as it looks.
Powerful Christmas Day winds gusting up to 114 mph severely damaged UC Lick Observatory on Mount Hamilton, forcing the nearly 140-year-old facility to close while officials headquartered at UC Santa Cruz assess structural damage and begin repairs expected to take months.

A little good news from the world’s fourth largest economy:

“From 2022 to 2023, GHG emissions per capita in California fell by 2.8% while inflation-adjusted GDP per capita grew by 2.3% over the same time period, demonstrating that climate ambition and economic growth can complement each other.”😎

This is the 15th year of #DuvetKnowItsChristmas, which is preposterous. Rules: if you find yourself dealing with unusual / claustrophobic / gaudy sleeping arrangements this Christmas Eve, share a picture with the world. Use the hashtag (with capitalisation) and cc me if you can be bothered.

I count 10 cities in 2025 that are on track to have the fewest murders since at least 1970. Newark is on pace to have the fewest murders since 1956 (though only have data through Oct this year) and San Francisco is on pace to have the fewest murders since 1942.

Happy holidays, Bluesky! I got you a megathrust earthquake, soil liquefaction, spine-tingling papers about the way our networks confound knowledge, and a PDF in a pear tree. It's my wrap on a year of trying to make sense of how we make sense of what's happening to us.

Amazing results in New York remind me how disappointing it is that congestion pricing efforts have stalled in San Francisco.

With congestion pricing, Muni service could be robustly funded, transit ridership would climb, and traffic through much of the Bay Area would significantly decrease.
Year 1 data on congestion pricing in Manhattan…

* Vehicle traffic: -11%
* Foot traffic: +3.4%
* Storefront vacancy: -0.9%
* Pollution: -22%
* Revenue for mass transit: $548M

So YES this has been a huge success.

Some important context here
I just wrote an article about this and decided not to publish it yet. It is in the DOJ files (file got renamed after originally published and taken down. It’s online now). But too many unknowns about whether the letter itself is real or not. Some additional info though:
DOJ briefly uploaded this letter from Jeff Epstein to serial child molester Larry Nassar:

"Our president shares our love of young, nubile girls. When a young beauty walked by he loved to 'grab snatch,' whereas we ended up snatching grub in the mess halls of the system."

The PR push around “we’re taking the power outage in the Richmond very seriously” lowkey icks me out for how much it de-centred the rest of the city. Thousands of people in Civic Center have no power OR water w/ yet another quiet delay, and narry a peep from Mr Vertical Video.

to inaugurate the new blog, i've written about a local and contentious topic that's been on my mind for years. at its heart, it's about understanding the information that transit riders need.

the case for splitting TTC Line 1:
Line 1 is not one line
In the long term, treating Toronto’s Line 1 as two different lines would eliminate more confusion than it would create.

Unlike many of Flock’s cameras, Flock’s Condor cameras track people, not vehicles.

The exposure highlights the fact that Flock is not just surveilling cars—it is surveilling people, and in some cases it is doing so in an insecure way.

If CPUC is not asleep at the wheel, they’ll be demanding a public retro of this Monday. Waymos in theory fail to the side of the road — why didn’t that happen here?

(lol, CPUC is asleep. Unfortunately, local media is very bad at covering regulators, so that will get ~zero headlines.)
Waymo has halted service in San Francisco after numerous videos & images showed its autonomous cars snarling traffic during the blackout.

With traffic lights down, Waymos across the city stopped dead in their tracks at intersections.

oh hey it's yet another Chronicle article about a "permitting nightmare" in which the reason we have rules (tenant created enormous fire hazard using space heaters because landlord failed to provide heating and there were no smoke detectors) is buried deep within the article and ignored
