don’t let this place fool you into thinking we aren’t the luckiest people in the world that we get to make things for other people who actually use the things we make
if you made something today, thank you. if you used something (or bought!) someone made, thank you
Honest question. I’ve heard a lot of talk about the new IPO bar for private companies. If the bar for exciting IPOs is $500B to $1T valuations in tech, what is the game plan for all of the $10-20 billion tech cos? They need 1-2 orders of magnitude of growth to go public and would be very very expensive acquisitions for the small universe of companies that could afford them.
Air Around a Race Car, Solved With Navier-Stokes
This is a real fluid simulation, not a drawing. The air around the car is solved from the incompressible Navier-Stokes equations:
du/dt + (u . grad) u + (1/rho) grad p = g + nu laplacian u
div u = 0
The solver is a lattice Boltzmann method with a Smagorinsky eddy viscosity (large-eddy simulation) on a 384 x 683 grid. The car seen from above, with front wing, wheels, sidepods and rear wing, points up, and the wind comes down from the top.
The lines are dye released continuously at the inlet and carried by the computed velocity. Teal is slower than the free stream, white is about the same, coral is faster. The faint shading is the vorticity, the spin of the air, teal one way and coral the other.
Watch the air pile up in front of the wing, speed up around the wheels and sidepods, and peel off the wheels and the rear wing as a swinging wake of vortices. The sound is made from the same run: the wind follows the energy in the wake, and every tick is a vortex shed from the car.
This is a 2D slice of the flow, so it shows the idea, not a real car's numbers.
Anthropic pre-IPO broker call was absolutely WILD. The party line was:
•We are or plan on imminently destroying: hyperscalers, every other lab, SpaceX, biotech, robot cos; for fun
•Chipmakers may survive at our pleasure
•$1tn ARR by 4Q28
•Fuck investors it’s capex time
thinking of a new startup idea:
obviously servers are good for agents. claude/codex need computers to do things with
what if there was a VPS that could spin up and down very quickly?
you only pay for it when it’s active. i guess I can do this myself with k8s, but that’s a lot of work.
there needs to be a platform that manages all of this for me
not sure why nobody is building this, feels like a pretty obvious play
That’s sounds cool but yes, I’ve tried similar and the gating. Factor for me is how my face/head feel after many hours in the Vision Pro
I think their gesture model is so great though, I am hopeful they are making another lighter device or that others are taking inspiration from their HCI
