  • Microwave scattering is an absolute nightmare over that kind of distance. Even for much shorter distances, microwaves are only practical to transport over a couple of meters in a waveguide.

    If its transmitting to a base station, we can assume it’s in geosynchronous orbit, or about 22,000 miles from the surface. With a fairly large dish on the satellite, you could probably keep the beam fairly tight until it hit the atmosphere, but that last ~100 miles of air would scatter it like no tomorrow. Clouds and humidity are also a huge problem – water is an exceptionally good absorber in most of the MW band.

    I saw numbers reported for the transmission efficiency somewhere (will update this if I can find it again), and they were sub-30%. The other 70% is either boiling clouds on its way down, or missing the reviever on the ground and gently cooking the surrounding area.




  • Zettlr! Its designed around writing manuscripts in markdown+latex, then exporting to pure LaTeX, PDF, or any other Pandoc-supported format via a builtin Pandoc GUI. The only thing that doesn’t work particularly well is the table editor, but they’re working on it.

    It is electron based, but almost all graphical editors for markdown + inline latex are (obsidian, etc.) because MathJax & KaTeX are the most mature method to render LaTeX inside other document formats.

    Obsidian is also good, but it’s not FOSS and their built-in export isn’t great.
