  • It’s admittedly confusing because electromagnetism is a unified field theory, and like I said, a bunch of pop-science YouTubers really make it worse. Current is defined as the rate of charge flow through a cross sectional surface of a conductor, which is caused by the electromotive force, which is simply a charge potential. The fields created by moving charge can be used to do work proportional to the current which creates them, but it is fundamentally the current doing the work.

    The misconception is that it’s not like one electron zooming down a wire, dumping energy into a sink, but the bulk change in how electrons, and therefore charge is distributed which moves energy around. Think about pushing something with a stick - the atoms near your hand don’t actually need to move down the stick to transmit force.











  • This has been an extremely obvious flaw in the modlog concept from the very start, and has been discussed on and off for years. IMO, it exposes a much wider issue with federated forums as currently implemented, despite the aggressive defense of some vague concept of “openness.”

    Blindly casting every user and mod action out into the universe in plaintext with no recall mechanism is problematic, and it will only get more problematic as the technical prowess of the average user drops. Doxxing is just the tip of the iceberg here, and I don’t think most people appreciate just how massive the social engineering attack surface actually is. Rogue instances could silently build engagement profiles on users, and then actually serve them targeted malicious content. This could be widespread, and almost impossible to detect.
