> One wonders if “A. Boogert” would have become a household name had his book been printed and distributed.

Would it have been possible to "print" his book? It is full of color swatches of different paint and water mixtures. Could printing processes have replicated this? How are modern color swatch books mass produced?

Can we infer what that visible light would look like unobstructed and with appropriate intensity to activate our eyes' cones?

The quote is confusing, because it's not always clear which Hall brother "Hall" refers to. Edward Hall, who developed the Minuteman missiles, was the brother of Theodore Hall, the spy. After reading the source article: <https://www.thenation.com/article/world/ted-hall-espionage-f...>, I can annotate the quote with first names:

"journalist Dave Lindorff, writing in The Nation on January 4, 2022, obtained through the Freedom of Information Act, Hall's FBI file in 2021. This 130-page file included communications between FBI Director J. Edgar Hoover to the head of the Air Force Office of Special Investigations, Gen. Joseph F. Carroll, showing that Carroll had effectively blocked Hoover's intended pursuit of [Theodore] Hall and Sax, probably fearing that [Theodore] Hall's arrest would have, in the political climate of the McCarthy Era, forced the Air Force to furlough and lose their top missile expert, Edward Hall. Carroll, a former top aide to Hoover before he became the first head of the USAF OSI, ultimately allowed Hoover's agents to question Ed Hall on June 12, 1951 (with an OSI officer monitoring the interview). Within several weeks of that session, the Air Force, which had conducted and completed its own investigation into Edward Hall's loyalty (having their own investigators question him four times), promoted him to Lt. Colonel, and later Colonel, and elevated him from assistant director to director of its missile development program. The promotions were a clear slap in the face to Hoover. Ed Hall went on to complete the development of the Minuteman missile program, and then retired."

I think you may have misunderstood the proposal. Your 3rd party library example would have to write `pystd2025::HashMap<pystd2025::U8String, size_t> member;`. Isn't that stable?

From the post:

  The sample code above used the pystd namespace. It does not actually exist. Instead it is defined like this in the cpp file:

    #include <pystd2025.hpp> 
    namespace pystd = pystd2025;

I download videos I use for teaching. In future classes, I can still provide students with the video even if it disappears from YouTube. This happens from time to time.

For C++, I've started using FetchContent as a kind of distributed package manager. When I think about it, why is that better than git submodules?

Two adjustable wavelength emitters should be sufficient, right? So the picking-and-placing problem gets easier by factor of 3:2 rather than 3:1.
