  • My first instinct would be that it would equivalent to putting another celestial body the mass of the earth at the distance from the earth is from each portal. Since gravity is a wave, it, in theory, would affect a region beyond what would considered “around” the portals.

    So if you put one portal on the ground, and another 100 meters up, it would be similar to there being a second earth 100 meters from the surface of the earth, experienced by the entire earth (once the gravitational wave propagated.) How that would evolve over time is too complex for my basic understanding of physics, but a simulation of it would be a neat experiment.

    pushd and popd are also pretty neat in that they allow you to change directories using a stack; particularly useful as part of that is that using pushd without any arguments will pop the directory on top of the stack and move you there, while putting your previous directory on top of the stack. When you’re working across directories where you need to move around within each directory, it can be really handy.
