From a first-principles point of view, fusion is the future, just like that big moving reactor in the sky. Gold is only a by-product, not the end goal here, and as a secondary benefit, the ~17-year radioactive cooling period is acceptable in the long term. It feels like a win-win if they can scale fusion itself to revolutionize clean energy, which remains the real challenge.
Last month, we demonstrated high-rate alchemy: turning mercury into real, stable gold, beating CERN’s record by a factor of 10. Last week, we enriched isotopes in the world’s most powerful plasma centrifuge, beating the Soviet record that stood for 40 years. Now, we’re building a fusion reactor in San Francisco to achieve record power density.

When the currency units are measured in fundamental physical quantities such as energy and mass, the speed of light will be the conversion constant.

This vehicle design is far more interesting as a technology demonstration for low-gravity environments than as everyday Earth performance hardware. These cold-gas thrusters would work ~6× better on the Moon and ~3× better on Mars.
Real life, baby

It all comes down to what do you manufacture. Electrons or atoms. AI is a factory for digital intelligence where you manufacture electrons.

Used to approve every step a coding agent planned. Thought that was caution. Now I just let it run. Not more trust, I can't read it fast enough anymore. The hard part is no longer watching the work. It's saying what I want to build before it starts deciding for me.

There are cathedrals for those with the eyes to see: not only in stone, but in steel that climbs.

TPUs in space will be tested soon with the ultimate nuclear fusion energy source.
After years of research, Project Suncatcher is scheduled to embark on its first test in orbit, launching a prototype satellite to evaluate how Google Tensor Processing Units (TPUs) perform in space. Learn more about the science behind this moonshot. ⬇️

Autonomy-1 will be a pioneer deep space mission.
Next year, we're going to launch a spacecraft that will be given zero commands from Earth after it separates from the launch vehicle. The spacecraft will attempt to complete all of its mission objectives with no human operator in the loop. Today we’re introducing Autonomy-1, powered by our spacecraft intelligence model, Solo. 🧵

Aiming the antenna to the correct point in the sky and getting reliable feedback that it’s properly aligned is one of the hardest challenges when building a ground station.

Posting my first @Starlink experience at ~11 km altitude with ~230 m/s relative speed. It’s magic.

1/ My LimeSDR Mini v2 suddenly died. Every time I tried to use it I got the following error on every frequency: TuneVCO(CGEN) - failed to lock (cmphl!=0) No sample rates worked, no RX, no TX. It looked completely dead.

7/ I’ve already contacted Lime Microsystems about this and I’m waiting for their reply. I don’t know yet if they consider this an acceptable workaround or if they have a better solution / will accept it as supported solution.

8/ If anyone is having the same CGEN lock issue on a LimeSDR Mini v2 and wants the full technical write-up + diagnostic scripts, just message me and I’ll send them over.
