  • You can listen to FM radio with gqrx relatively easily, if you can navigate through hundreds of input boxes.

    sudo apt-get install gqrx
    

    Anything more complicated will require some coding knowledge, unless someone already created a library for that specific thing.

    There is also a ready-made package to listen to GPS signal, unfortunately it needs an external amplifier and a proper antenna, because RTL-SDR is not sensitive enough for GPS.






  • So if I’m developing a garage door opener using ESP32 RISC-V module, I’m not a RISC-V developer? The dev tools and the cross-compiler only come in x86_64 variant, they simply won’t work on RISC-V laptop. But at least they provide a Linux installer.

    The only use case I can think of is to build Debian packages on a target architecture without cross-compilation, because many packages do not support cross-compilation, but it’s more an issue of poor build scripts.





  • Busybox was quickly replaced by BSD-licensed Toybox everywhere for that exact reason.

    Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free.

    This is false. It’s perfectly legal to take GPL-licensed work, modify it, and sell it. As long as the work itself does not reach the general public, you don’t need to release it’s source code to the public (e.g. your work for the military, you take money for your work, and provide source code to them, but not release it publicly).
