  • all the way from 1991 to 2024, I think the only other OS that has managed that is Windows

    It’s easy to forget about MacOS when it only has 15% desktop market share.

    Operating systems that started before 1991 that are still in active development (had a release in the last 12 months):

    • Multics (1969-)
    • MVS (1974-) via OS/390 (1995-) -> z/OS (2001-)
    • VMS (1977) via OpenVMS (1992-)
    • BSD (1978-) via 386BSD -> FreeBSD, NetBSD -> OpenBSD
    • HP-UX (1982-)
    • SunOS (1982-1994) via Solaris (1992-)
    • MacOS (1984-)
    • AIX (1986-)
    • RISC OS (1987-)

    Almost made it:

    • Minix (1987-2017)
    • Genera (1982-2021)
    • AmigaOS (1985-2021)
    • NeXTSTEP (1987-1997) via GNUStep (1993-2021)
    • IBM i (1988-2022)
    • SpartaDOS (1988-2022)

    Correct. A piece of paper with the golden (aspect) ratio would have the property that if you remove the large square (with side length equal to the shortest side of the rectangle) then the remaining rectangle has the same (golden) aspect ratio.

    The ISO216 ratio of 1:sqrt(2) has the property that if you cut the paper in half then both halves have the same aspect ratio as the original larger piece.

    People tend to confuse these two properties as they both involve the remaining rectangle having the same aspect ratio as the original piece, but the process to bisect the sheet is different.


  • Why not post your blogs to a fediverse platform? Do they need to be on a separate hosted system? You’ll probably get more people reading and engaging with your posts if you are just posting to a Mastodon instance rather than hosting on a separate web platform and hoping that people stumble across it.
