NuttX runs on the ESP32[1] which provides a rather featureful shell[2] as well as a file system.

As others have already pointed out this exercise used a huge dish(a radio telescope[1]) and significant power. This is in no way an economically viable mode of communication. Using satellites in low earth orbit requires less power and a significantly smaller antenna. Putting LoRa on satellites has been done before, see e.g. [2].

No, the radio waves bounce off the moon's surface. The retroreflectors are not necessary for that, otherwise stuff like Earth-Venus-Earth bounces[1] would not be possible.

For reference (mostly for me as I need this from time to time), you can do the same on dpkg-based distros with

     $ dpkg -L imagemagick-6.q16 | grep bin
     /usr/bin
     /usr/bin/animate-im6.q16
     /usr/bin/compare-im6.q16
     /usr/bin/composite-im6.q16
     /usr/bin/conjure-im6.q16
     /usr/bin/convert-im6.q16
     /usr/bin/display-im6.q16
     /usr/bin/identify-im6.q16
     /usr/bin/import-im6.q16
     /usr/bin/mogrify-im6.q16
     /usr/bin/montage-im6.q16
     /usr/bin/stream-im6.q16
Similarly, you get

     $ dpkg-query -S /usr/bin/convert-im6.q16 
     imagemagick-6.q16: /usr/bin/convert-im6.q16
This does not work for the canonical executables though as they are just symlinks to /etc/alternatives/foobar

May I ask what made you choose lazygit instead of fugitive? I'm using the latter and am quite happy with it, but I'm keen to learn what I'm missing out on.

Do you use the native-comp branch of emacs? This probably doesn't make any difference when it comes to multithreading but it should make the experience a bit more smooth.

You might want to consider using the BR2_EXTERNAL feature[1] to keep your customizations outside of the buildroot tree.

I guess this is a thing you could achieve with neovim-remote[1]. My main use case for it avoiding nested neovim processes in the inbuilt terminal, though

Speyer has the Buran as well

The easiest way to leave the gray zone would be to get a ham radio license. Although this might vary from country to country, generally you are allowed to use selfbuilt transmitters in specific frequency ranges, which also includes noncertified hardware.
