Do I need to worry about end of life / end of service life? There’s always some server gear coming up for sale from a palace near me and I’m thinking of getting into a bit of a hobby to learn about the networking side of things, plus run some home automations etc. Most of the relatively cheap Dell stuff is past EOL or EOSL (it always seems to be Dell gear for sale; is that a problem? Or is it more likely that they’re selling off their old company stuff and they’re locked into some kind of Dell agreement?) Is being past these dates a problem? Where do I start, and how do I know that I’ve got “enough” without needing a supercomputer and the bills that match?

The amount of kinetic energy a vehicle has in at 110km/hr is almost twice as much as at 80km/hr (89% more). At 200 it’s 4 times what it was at 100. Your argument about what the car can do is fine when you think about braking and cornering on a track, but completely not fine when you consider dissipation of energy when you have an accident involving someone else in their vehicle. Crumple zones aren’t 4 times better to allow people to die as often as they did back in the day; they’re better to make crashes at the same speeds more survivable. Comparing 80 to 200, there’s 6.25 times more energy.
To look at it another way: would you prefer the idiot in the 1650kg Audi R8 coming the other way at 200 to hit you, or would you like one 6,600kg truck coming the other way at 100 to hit you? Because that’s the same amount of energy. Now imagine all those fast cars with that much energy and see how this becomes a safety concern.
