One source, maybe not the origin, but close. Maybe someone threw a physics text at these yahoos and that’s why they’re hyping data centers in spppaaaaaace and kardashev now.

A slide from the linked presentation titled “Boil the Oceans” with the text: it has been shown that 1 kilogram of matter confined to 1 liter of space can perform at most 1051 ops per second on at most 1031 bits of information A fully-populated 128-bit storage pool would contain 2128 blocks = 2137 bytes = 2140 bits; therefore the minimum mass required to hold the bits would be (2140 bits) / (1031 bits/kg) = 136 billion kg. That's a lot of gear. To operate at the 1031 bits/kg limit, however, the entire mass of the computer must be in the form of pure energy. By E=mc, the rest energy of 136 billion kg is 1.2x1028 J. The mass of the oceans is about 1.4x1021 kg. It takes about 4,000 J to raise the temperature of 1 kg of water by 1 degree Celsius, and thus about 400,000 J to heat 1 kg of water from freezing to boiling. The latent heat of vaporization adds another 2 million J/kg. Thus the energy required to boil the oceans is about 2.4x106 J/kg * 1.4x1021 kg = 3.4x1027 J. Thus, fully populating a 128-bit storage pool would, literally, require more energy than boiling the oceans.

Damn. It could at least tell you that the “task failed successfully”

Or my favorite:

I kinda regret not going mono when I had the opportunity — but clear skies tonight! First all year here.

Since they inexplicably gave me video, here’s Eddy getting into some grass for @darthbluesky.bsky.social

If you see this, post a photo you took at sunset.

M81 is a pretty small target for a RedCat 51, but does let you get the neighboring galaxies in the frame. #Astrophotography
