HiPER Calc Pro. A great scientific calculator I use constantly. (There is also a unpaid, ad-supported version, and the ads weren’t too intrusive the last time I tried it)

A small pair of vernier calipers. I don’t use them a lot, but sometimes they come in very handy.

If that freehub is constructed like the ones I’ve taken apart before, you’re out of luck. Like you suspected, the teeth lock the rotation of the freehub to the hub, unless the screw in the back is taken out first.

You can try hammering in a (slightly larger) torx key or using an easy-out (probably won’t work if it’s very tight).
As a last resort, you could try to drill out the screw (only so far that the freehub comes off, you don’t want to drill into the hub). Then you should hopefully be left with enough left of screw to grab with a pipe wrench.

It is more efficient to have a ship moving with cargo than without, but that doesn’t mean there aren’t additional emissions. The ratio of profit to effort is just higher because there is some profit as opposed to none. You wouldn’t load a ship up with useless mass you can’t sell just so you’re shipping something.

Your argument is like always running the heater in your car because that way the engine heat is at least used for something. Yes, technically the efficiency goes up because more of the energy in the fuel is harnessed. But that doesn’t mean the fuel usage or emissions are any lower, and in the summer the heater doesn’t do you any good either.

That study states that brain damage can cause more conservative views, but the reverse isn’t true. Not everyone with conservative views has brain damage.

Matlab

I have the exact same setup and also didn’t get the warning yet. Maybe pihole stops the AdBlock detection?

One of my monitors has had a couple of dead pixels for a couple of years. I still find myself wondering sometimes if that dark spot is part of the image or just my crappy screen.

Incandescent oven bulbs will probably not be replaced, simply because there is no reason for it. The “wasted” energy from an incandescent bulb is expelled as heat, and extra heat in an oven is not a problem. You can describe the bulb in an oven as a tiny heater that just happens to give off a bit of light.
