[ #Waves and #Plasma] Numerous #moons orbit #Jupiter, including #Io, whose volcanic activity causes the ejection of #matter and the formation of a magnetized #plasma disc—or #magnetodisc—in the equatorial plane of the gas giant.

How does the plasma in this magnetodisk manage to remain in a state of #equilibrium? By emitting waves, according to a new study based on data acquired by the #Juno probe, which has been orbiting #Jupiter since 2016.

How I turned Zig into my favorite language to write network programs in

I’ve been watching the Zig language for a while now, given that it was created for writing audio software (low-level, no allocations, real time). I never paid too much attention though, it seemed a little weird to me and I didn’t see the real need. Then I saw a post from Andrew Kelley (creator of the language) on Hacker News, about how he reimplemented my Chromaprint algorithm in Zig, and that got me really interested.
