Every CFD engineer knows the pain of kicking off an overnight run, only to come back to diverged residuals, a bad mesh, or wasted compute.
@NavierAI's Agent monitors the run, catches issues, updates the setup, and restarts automatically. Finally starting to see the possibilities hands-free CFD.
I respectfully have a different take...
A major vendor, @UnionPacific, decided to paint one of its locomotives in patriotic colors to celebrate America’s 250th birthday as it transports components of a NASA rocket. They also decided to paint “45 47” on the train to recognize the sitting President during this important anniversary. Now, I understand if someone served in a different administration, from a different political party, there may be a bias, but through my lens, what Union Pacific is doing is patriotic.
We also happen to be celebrating a lot of NASA’s “meaningful achievements,” including the giant Saturn V, the Moon landing, and other historical moments projected on the Washington Monument during America’s 250th birthday. We similarly have those accomplishments displayed at NASA centers to recognize these historic and world-changing achievements, but it is unlikely we can ask vendors to paint them on every locomotive.
All D.C. needed was President Trump!
After years of neglect under Biden, @POTUS brought life back to one of our capital's most visible public spaces, restoring flowing water to the Columbus Circle fountain after 2 DECADES!
Decline is a choice. @POTUS is choosing differently.
Never in my 13 years living in DC have I seen this fountain on.
Honestly, I don’t think many Washingtonians thought it would ever come back, especially after last year’s protests.
It’s more beautiful than I expected.
This is a terrible take.
The @blueorigin team is about to learn so much about their rocket.
Space is hard and a failure on the pad sucks, but the post-failure investigation and subsequent updates are going to make NG an even better rocket.
Did they executed every single rocket scientist after the end of the space race of something? Why are they basically redoing everything from scratch? By 50s having your rockets blowing up were already considered a deep embarrassment, but now it's standard operation.
I interview dozens/hundreds of new grads, nearly every day of the year. These are people with a well-formatted resume and a Bachelor's Degree in Engineering from well-regarded US universities and a GPA above 3.6. The majority cannot engineer, cannot function independently, cannot answer basic technical questions. We have watered down standards and inflated grades to the point that a bright, enthusiastic student spending four years in school sends almost no signal at all.
What does? Hard evidence of actually building stuff. There is no substitute for actually doing the thing.
Rough day for Blue Origin, but very glad to see no injuries.
Early video makes this look like it occurred just after ignition, which is a very different failure regime than Falcon 9’s 2016 AMOS-6 pad loss during propellant load. In that case, SpaceX traced the failure to oxygen trapped around COPVs in the 2nd stage LOX tank.

Also glad they didn't have a customer payload integrated - definitely learned from SpaceX there.
How do you design a CLI for both humans and agents?
That's the question behind ntn — the Notion CLI. Carter and Anthony break down the 4 principles that shaped it.

Pretty CFD pictures are cool.
Pretty CFD pictures that help you make better engineering decisions are the point.
Quick look at some of the visualization tools we’re building in @NavierAI:
Aero workflows shouldn’t require days of manual setup, babysitting runs, and stitching together reports.
We’re building Navier so engineers can go from intent → simulation database → insight with dramatically less friction.
The Navier Agent turns one prompt into an end-to-end aero simulation workflow:
• Dynamic compute, up to 192 cores
• Run management
• Automated issue triage
• Report generation
Today marks the beginning of a new era.
Introducing: Cowboy Space Corporation.
We are building orbital infrastructure for the AI era: a fully integrated system of rockets and satellites designed to deliver high-performance compute and optical data transmission directly from Low Earth Orbit.
