It was Jack Lance, who wrote Enigmash. Tragically, he died in 2023 at the age of 25. Jack Lance superlatively creative. I cannot find the words to express how much the world lost. I do not know of a finer puzzle designer.

Oops, you're right. I read that factoid [1] while searching for information about the 2025-077C, but it was about a different 2021 launch.

I think there are only two US rocket stages in LEO that were launched in the past 21 months:

1. 2024-125H — Firefly Alpha FLTA005 Stage 2, launching demo cubesats for NASA

2. 2025-077C — Orbital Minotaur IV (8) Stage 4 (Orion 38), launching a few spy satellites

Fun fact: the first stage of the latter rocket was manufactured in 1966.

> For about $6,000 a pair of Nvidia Project Digits offer about a combined 2 petaflops processing and 256 GB VRAM.

2 PFLOPS at FP4.

256 GB RAM, not VRAM. I think they haven't specified the memory bandwidth.

Are you comparing tinybox red with 738 FP16 TFLOPS at $15K to Project Digits with 1 FP4 PFLOP at $3K? Or did they announce the Project Digits FP16 performance somewhere?
