  • I didn’t read much on the subject, but I have tried and owned keyboards of several sizes. At first I thought I couldn’t live without function keys and a numpad, but you stop missing them real soon once you get used to customizing layers. So I bought a TKL (80% size) board and loved it. Then I started experimenting with smaller boards and weird arrangements, and drew the line at ortho layout – not only was it not teaching me to be a better typist, it also felt like it was bad for my wrists. I don’t have carpal tunnel or RSI and hadn’t had any issues with normal layouts so I wasn’t looking for anything ergonomic until I tried a friend’s Alice keyboard. It just clicked, I felt like I could actually keep my hands on the home row, there were few enough keys I could reach them all without looking, but enough that normal typing didn’t require weird chords and stuff.

    Try some things out at Micro Center or whatever and see what you like

    Best intuition I’ve heard for this is that “things” can’t move faster than light, but not everything is a “thing”.

    Imagine doing shadow puppets on the wall with a flashlight. You move the bunny left, shadow moves left. The further away the wall is, the faster the apparent speed of the shadow bunny. You might think that, far enough away and with a strong enough light, your shadow bunny would be racing across the sky faster than the speed of light – and the crazy thing is, you’d be correct! The shadow (absence of light) can move arbitrarily fast. But the light itself is moving at its normal constant speed from the flashlight out into space, perpendicular to the travel of the bunny, like a garden hose spraying water. The time it takes for the shadow to even begin to move is governed by the speed of light. No information can be communicated faster than light because the light travels at the speed of light to illuminate the places where the shadow isn’t.




  • Would a nuclear or fossil fuel turbine power plant just tear itself apart if disconnected from load at speed? I vaguely understand that the load provides a sort of magnetic resistance on the spinning generator. Without load they would they spin too fast? Or is it a matter of there not being any easy way to dump the power by doing something useless with it like just melting sand or smth?
