AMOC shutdown is unfathomably catastrophic. You know how Toronto is the latitude of Marseille, but much colder? Imagine European latitudes with Canadian climates.
During the last AMOC shutdown, the winters in Paris were similar to Winnipeg, UK summers similar to Reykjavik.

Whilst its easy to get used to scary graphs, this one made me pause! The 2025 State of the Cryosphere report published yesterday has this one overlaying observations of #AMOC slowdown against model predictions.
The report states that “AMOC shutdown appears all but inevitable”

When I wrote about Mamdani's primary victory, I focused a lot on how Islamophobia formed the unspoken core of the campaign to label him antisemitic.
Predictably, his opponents tried to turn this up to 11 during the election, and I'm glad it failed.

Fewer than 10 users block me on bsky apparently, but among them is my favorite band, who:
1. last released an album in 2012
2. I saw live at least 20 times
3. follows me on twitter
Oh! turn to water, sublimate to steam,
then form a cloud and pour on me.

The quote "Trump will be President in '28" is, barring his death or removal, correct; his term ends in '29. This feels like a dumb nitpick, but I think it plays into the subconscious narrative that Biden was somehow President in 2020 and is responsible for the pandemic response.
this week's newsletter has a bunch of quotes from the drafters and supporters of the 22nd amendment that make it extremely clear that there is no loophole you can use to circumvent it. (gift link)

Every $TSLA quarterly announcement this year has been "we can't even give away our cars and the macro is getting worse" followed by a fabricated timetable for one of their vaporware projects, and the market reaction is "this guy's a genius lets give Musk literally a trillion dollars"

Very encouraging that Zohran is not just about moonshot programs that will be difficult to enact given the limited powers of the Mayor.
There's plenty of waste from overlooked government operations and graft from corrupt NYS dem machinery that would be valuable to clear out.

NYC’s Dept. of Education spends around $10 billion/year on contracts.
Many provide essential services to our schools, yet with over 3,000 active contracts, DOE faces major efficiency challenges.
DOE needs procurement reform.

I listened to Ezra Klein's latest with Ta-Nehisi Coates and I thought it was pretty good? I'm far more on Coates' side, and I think that Klein is trying to recapture a dead past and build a coalition that no longer exists, but his fears and his goals make sense to me.

It's fascinating to see this being written ~75 years ago, though it has many anachronisms.
The rules around contact in NFL are far too dangerous. Many routine NFL tackles are illegal in Rugby. The helmet is used as a weapon, but this is also where the player's head and brains are stored.

Even a Nadal guy should see this earlier, but hey, a good TCW take.
Real ones know the best tennis comes from the eccentrics (Moutet, Cuevas, Bublik, 'Penko), the artists (Federer, Henin, Muchova) and "the kid" (Alcaraz, Fonseca, Andreeva).

After a 4-6 weeks of playing around with Claude Code, I've been trying out Codex w/ GPT-5. I think it writes prose more like me, but Claude codes more like me (and comments better).
Codex has a tendency to discard edits you've made manually, which I could see being intensely frustrating.

Not the biggest issue but surely the better nerd opposite for micro is mega.
a few takeaways:
- Musk is serious about building a software competitor to Microsoft, called Macrohard
- Grok has about 64 million monthly active users
- Musk's efforts to make Grok less woke & more popular triggered the 'white genocide' and MechaHitler incidents
- some employees quit over sexbots
