@om_patel5 Super cool.

Next step is to add LiveATC to listen to the pilots and air traffic control for that plane overhead.

@simonsarris Sir, it is called diet coke.

@MichaelDell 7.6x yoy on AI server growth is insanely good. I bought some Dell stock.

@boxcardavid Laser cut, laser welded?

Pretty

@Robotbeat There is dogma is every field that can be deleted with a few small tweaks to the basic assumptions.

It’s time to America-maxx. 🇺🇸💪🚀

To clarify, the current terminals can support peak download speeds of 400-500 Mbps. The 220 Mbps number is referring to actual in-flight performance given that the satellite to user beams are shared amongst users. For larger commercial planes, we allocate more resources to ensure sufficient bandwidth.

Other providers quote peak speeds as real performance, which is only relevant if you have very few users. @starlink quotes real performance measured via automated network performance tests.

The latest aviation terminal supports two channels, so up to 1 Gbps peak speeds per terminal (the A380 design consists of 3 of these terminals). We will continue to increase peak bandwidth per terminal in future revisions.

@svershbow I loved Book It

What an amazing showcase of the excellence that is the @SpaceX team.

[SpaceX @SpaceX]

Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket

@oliverbrocato True facts. Also wildly optimistic.

[Ben Longmier @longmier]

Pretty cool.

I’m not sure what your goals are, but if you desire 1e14 #/CC plasma density, I have had much better results with simply a half twist antenna, and a capacitive matching network with a very short distance to the antenna.

The goal is to also launch the helicon wave into the downstream section of the cusped field beyond the permanent magnet.

PS: it is not published, but one can achieve 1e16 plasma density at a 1-2 T magnetic field. Kind of insane outside of the fusion world.

Godspeed!

Ah yeah, %GDP is a much better plot.
Holy smokes, yeah the railroads really were crazy. Opened up the Western states for business and living though.

Rockefeller was a ruthless mf, and then separate statement: his empire building and Standard Oil really lucked out on the timing of the railroad expansion.

@finmoorhouse Wow. The Manhattan Project was a lot of bang for the buck.

[Ben Longmier @longmier]

@elonmusk @Tesla_AI It’s a beauty.
48Vdc input?

Any plans to run inference with more general LLMs? Is there an equivalent tokens/s/W for say a 0.25T model?

[Ben Longmier @longmier]

@_vmlops This is really useful, thank you.

[Ben Longmier @longmier]

@beffjezos Gradient ascent if you will…none of this AI gradient descent baloney, oh wait.

[Ben Longmier @longmier]

@lougrims @RocketLab Ha yeah, I know how it goes. It was a good promo.

The camera view flying through the plume was fun.

@MollySOShea SpaceX to the Moon!
