@planet4589 Did the first stage under-perform? It looks incredibly slow coming off of the pad.

A second orbit dataset from SpaceForce for the BlueBird-7 sat shows it in a 265 x 485 km x 43.0 deg orbit, indicating that the upper stage delivered about 1000 m/s, mostly changing orbital inclination. This is about half the dV that would have been needed for the target orbit

How do they support tons of dirt without falling over?

On the complete opposite end of things... If you have plastic or rubber parts, you can use liquid nitrogen or dry ice to freeze the burrs & flashing, then tumble or blast them away. All other surfaces are left pristine & clean. Cryogenic deburring. So cool. (video clips from Cold Jet Australia Pty)

when I look at my old simulations, a lot of them, most of them, can be easily vibe setup with agents, or even one shot by the agents. it makes me wonder how many of the ideas and devices that were results of branching off of originally intended directions and goals would I miss if I attempt them now with the agents? How many new ones would the agents be able to attempt and identify? Is inverse design just the most stupid and bruteforce version of auto research? i should get a workflow with MOOSE working so I could set the agents free in the world of multiphysics simulations.

I wonder how the first person figured this process out? > grab a part that's loaded with sharp burrs > stick it in a chamber filled with gas > ignite that puppy > boom > your entire part is smoothly & accurately deburred, inside & out. Thermal deburring (also known as TEM, or explosive deburring) folks. Yet another method of making stuff smooth. I have to try it. (video clips by Extrude Hone)

Tom Mueller, a former SpaceX engineer, explains why Elon Musk never allowed negativity to take root inside the company As a founding propulsion engineer, Mueller described how Musk shaped SpaceX’s early culture around intense technical focus and constant urgency. Teams were expected to stay aligned, move quickly, and prioritize solutions, with little tolerance for negativity or resistance to progress Mueller noted that individuals who consistently slowed momentum or spread negativity often “were not in the next meeting,” reinforcing a strict, results-first mindset This high-pressure environment helped SpaceX build its reputation for speed and innovation, advancing rapidly from its earliest rockets to fully reusable launch systems and ultimately becoming one of the world’s leading space companies

In 1944 the U.S. War Department made a training film explaining Frequency Modulation for battlefield communications. Oscilloscopes. Hand-drawn diagrams. Pure first principles. It teaches FM clearer than most modern EE courses.

Here's a PCB project I've been working on. For all the programmers out there, pcbs are your way to start manifesting tangible things.

@grok @tesla_archive @tesla_robotaxi Assuming the same recent grow rate of both companies, when will Tesla surpass Waymo in the Bay Area?

@DonAutomaton @tesla_archive @tesla_robotaxi As of Feb 2026, Tesla's Robotaxi fleet totals 303 (215 in Bay Area, 88 in Austin). Waymo's fleet is ~2,500 overall; late 2025 estimates show ~800-1,000 in SF/Bay Area and ~200 in Austin. Waymo leads in scale and ride volume (~450K weekly).

🚨BREAKING: $TSLA ROBOTAXI FLEET PASSES 300 MARK The latest @Tesla_Robotaxi tracker shows 88 units operating in Austin and 215 in the Bay Area for a total fleet of 303 vehicles—though the actual number of active Robotaxis is likely even higher

Watch closely. This is not random. This is not chaos. This is engineering… precision… design operating at a scale most people never slow down enough to see. A spider doesn’t just “make a web.” It deploys multiple spinnerets on its abdomen… each producing different types of silk with distinct tensile strength, elasticity, and adhesion properties. Structural lines… anchor threads… capture spirals… all laid down with mathematical efficiency. No blueprints. No rehearsal. Just instinct written into biology itself. And yet the result rivals human engineering. Silk stronger than steel by weight. Geometry optimized for vibration sensing. Energy efficiency built into every movement. This is the glory of God’s Biology… where even the smallest creature reveals intelligence woven into creation. The more you look… the more impossible it becomes to call this accidental. Slow down. Watch. Witness the masterpiece happening in real time. #SilentMajoritySpeaks #AStoneGroove
