Here it is: my 12,000 word report on Space Warfighting. Handed it to Space Force leadership two weeks ago, and it's now public. My core argument: No amount of wishful thinking can keep us from having to fight a space war. So we had better learn how to win one. Contents: The First Principles of Space Warfighting ▸ Space is close to earth, but it’s hard to get there. ▸ Orbits are predictable, but tracking objects in space is hard. ▸ Space is physically massive, but operationally small. How To Win a Space War ▸ Maximize upmass to orbit. ▸ Scale commercial satellite manufacturing. ▸ Disaggregate and proliferate military satellite systems. ▸ Dominate the cold war. ▸ Defend the domain.

Round 2, The actual Fourth!
Best of the shots from today's practice in DC. As usual, shot on my vintage Rokkor-X 50mm and A7IV.

I wonder what made FIFA change their minds
BREAKING @TheAthleticFC Folarin Balogun will be available to play the USMNT’s round of 16 match against Belgium with his one-game red-card ban suspended. Extraordinary development. Story with @Dan_Sheldon_ nytimes.com/athletic/7423410…

The bifurcated economy in question
Why can’t people accept that the sweet spot is probably that “free market capitalism” works best for goods and services that are non-essential and “socialism” works best for goods and services where life/health/education takes priority over profit? A bifurcated economy?

I'm giving my extended family a Ted Talk today — "AI 101." We're all together this summer, and they love me, so they will humor me & attentively listen for ~30 min. What should I cover?

78 degrees
New York: it's hot out there, and the power grid is working overtime to keep us cool. Set your AC to 78 degrees, turn off lights/electronics you're not using, and unplug what you can. Our City is doing its part too: maintaining the 78 degrees rule in our buildings, dimming/turning off our lights during peak electricity demand, asking private partners to do the same, and powering down non-essential equipment. A stable grid means the AC stays on, and lives are saved. Let's ease demand — and get through the heat — together.

Incredible: In 2025, SF gave out more new dog licenses than it had human births.

in the 2000s my university charged like $300 for summer storage BUT you could buy surplus FIM-29 Stinger launcher cases for $200 so i put my clothes and books in one, sunk it in the river by my dorm, and retrieved it fall semester they’re hard to find now and i regret selling it

Kane is one of the most interesting VCs I've ever met. (Not exactly the highest bar, sure... but also he stored his college stuff in a FIM-29 Stinger launcher case at the bottom of a river, rather than put it in an overpriced storage locker over the summer.)
Kane Hsieh (@kane) is a GP at @rootvc, which has backed multiple unicorns, all in the world of hardware. On episode three of Cars and Capitalists, Kane and I discuss: 00:00 - Cigarettes with asbestos filters 04:40 - The evolution of crabs, compared to consumer hardware. 10:42 - How shipping parts overnight is faster than 3D printing 13:05 - Why the Japanese can create an excellent taco and the British never will 15:17 - Why there may never be an LLM for generating CAD 23:00 - Humanoid robots are meh 24:40 - The founder who built his own airplane 24:42 - The best way to consume nicotine 28:55 - Asbestos, the miracle insulator 31:23 - Smoking Pipes 33:56 - How to eat the Mona Lisa 37:23 - Be a dumpster fire. Everyone else is doing it.

If the Founders visited us today, I think we'd have to start by saying this:
Ossoff: "Just think, 250 years on, what the Founders would see if they visited us today. *crowd groans* But wait -- they would see that slavery had been abolished. They would see that Americans without land, and then women, and then the descendants of slaves had secured voting rights ... "
