TheDudeMan··on Fusion tech finds geothermal energy application
Technology and workforce are not the limitation of nuclear.
TheDudeMan··on Fusion tech finds geothermal energy application
Likely condenses into dust in midair and gets blown out.
TheDudeMan··on Fusion tech finds geothermal energy application
I don't think TBMs (tunnel boring machines) have the same problems as mechanical deep-well drills. For instance, you can replace worn components of a TBM without extracting the entire mechanism from 100s of meters of earth. Whereas vaporizing a 10-meter wide tunnel would require an insane amount of energy. Plus you'd have to deal with the slag trying to flow back toward your equipment.
TheDudeMan··on Small modular reactors: Still too expensive, too slow, and too risky [pdf]
55 is a tiny number in manufacturing.
TheDudeMan··on Multi-Array Queue
Why not also a multi-array List?

It is buried while it runs. At end-of-life, you dig it up and properly dispose of it (whatever that process may be).

Nuclear fuel is about 20x cheaper than diesel (per unit energy).

TheDudeMan··on Small modular reactors: Still too expensive, too slow, and too risky [pdf]
You don't need distribution for a small enough reactor -- you use the electricity on site.
TheDudeMan··on Small modular reactors: Still too expensive, too slow, and too risky [pdf]
Ideally, the reactor would not need service until end-of-life (e.g. ~10 years). That way, it can be encased in concrete and buried.

"Too Expensive, Too Slow, and Too Risky"

Because they are still too big. They must be very small. Fuel efficiency is less important than creating economies of scale in manufacturing.

TheDudeMan··on Carmakers Will Give Your Location to Police Without a Warrant, Senators Say
I suspect that you mean "Police told me they didn't have any way to track it." Maybe they had a way but no motivation.
TheDudeMan··on A skeptic's take on beaming power to Earth from space
It might only be viable if the majority of materials come from off-Earth, like the moon.
TheDudeMan··on A skeptic's take on beaming power to Earth from space
All nuclear power is also extra heat for the earth.
TheDudeMan··on Nasa’s proposed plasma rocket would get us to Mars in 2 months
"hopefully the price of this rocket to get stuff off of earth is dirt cheap"

This is not a launch technology.

TheDudeMan··on Lithium-free sodium batteries exit the lab and enter US production
Plug-in hybrids, that is.
TheDudeMan··on Insects and other animals have consciousness
Just because memories are not persisted? Or some other reason?
TheDudeMan··on Lithium-free sodium batteries exit the lab and enter US production
True, but they win despite that.
TheDudeMan··on How hard can generating 1024-bit primes be?
Another option is to do N sequential candidate tests for each fresh random candidate. Where N is something that gets you most of the speed advantage of doing all sequential tests. Maybe like N=16.

Nice write-up!

TheDudeMan··on Horizontal running inside circular walls of Moon settlements
It's easier in space. I suspect it will happen there first and predominantly.
TheDudeMan··on Early Bitcoin Investor Roger Ver Charged with Tax Fraud
Interesting title by justice.gov. Tax evasion is illegal regardless of your background / investment portfolio, so why relevant? Sowing sentiment?
TheDudeMan··on Crash-only software: More than meets the eye (2006)
Your comment suggests that you believe crash-only software to be inherently less reliable than the alternative. But that is opposite of the stated goal and supposed benefits.
TheDudeMan··on Crash-only software: More than meets the eye (2006)
Idempotent APIs + sane timeouts + retries.
TheDudeMan··on Jeff Geerling: Corporate Open Source Is Dead
I just watched this interesting Node.js doc (Open-source Node.js was purchased by a corp and there was some drama along the way).

TheDudeMan··on The AI Lie
CO2 emissions are ripping and will continue to do so in China and India. You can't stop that train, either. https://ourworldindata.org/grapher/annual-co2-emissions-per-...
TheDudeMan··on The AI Lie
You can't stop this train.
TheDudeMan··on NASA Technology Helps Guard Against Lunar Dust
It would be nice to see a demo video.
TheDudeMan··on Astronomers discover Milky Way’s biggest stellar black hole
"Sagittarius A has the combined mass of several million suns. It lurks at the heart of the galaxy and formed not from an exploding star but the collapse of vast clouds of dust and gas."

How is that known? Isn't "dust and gas" also how stars form?

TheDudeMan··on RocketStar tests fusion-enhanced in-space propulsion process
If this is really fusion, is it not a possible avenue for a fusion power plant here on Earth?
TheDudeMan··on The xz sshd backdoor rabbithole goes quite a bit deeper
Yet most murders go unsolved.
TheDudeMan··on Favorites from our prompt engineering tournament
So silly to call it engineering.
