I agree that this feels intuitive, that potential energy should increase linearly with height.
But in the end, it's all up to the units/quantities we choose to measure, no? If we, say, decided to measure "Squenergy" in Sqoules, with 1Sq² = 1J, then suddenly, squenergy does increase linearly with speed! The formula for kinetic Squenergy becomes sqrt(m/2)v.
Of course this complicates other stuff, like potential Squenergy becoming sqrt(MgH), it not being additive, etc.
I love nextcloud and have been using it for years. However recently I've considered taking my instance offline or at least behind a VPN because even if only 10% is true of what AI folks are claiming about LLMs finding exploits left and right, it seems super risky to be hosting your private data on nextcloud.
How do you folks deal with these massively increased threats to self-hosted open source apps?
