  • why does the author rely on `pv` when `dd` has a status flag to display its progress already

    Not all versions of `dd` support the status argument. I think it’s particular to GNU. If you’re working in a shop that runs multiple versions of Linux as well as multiple versions of proprietary UNIX then you tend to use the command that works everywhere rather than remember the exceptions for each. (I worked in a place that ran all of RHEL, SLES, Ubuntu, AIX, Solaris, and SCO UNIX).







  • I’ve been thinking about a toroidal world for literally decades, on and off.

    (This is a magic planet for fantasy based role playing games, so I don’t really care too much about real physics or gravity. Anything that doesn’t fit physics “just works” because it’s magic).

    I have notebooks full of maps and diagrams, trying to work out how to map it (possibly two equators, no singular north and south poles), how the cycle of day and night; and seasons; would work. What would the view be like from the “inside” of the donut hole? Is it better to rotate “horizontally” around the centre of the donut hole (I think so) or “vertically” around a north and South Pole on the planet?
