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)

You can host a Firefox sync server yourself. You could run that on something like a Raspberry Pi in your local network. If you need remote access, use something like cloudflare tunnels (although I guess that’s something else to be paranoid about).

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.

It’s called HDR (High Dynamic Range) photography. Your phone is taking three pictures: one at a medium exposure, one at a bit higher exposure and one at a bit lower exposure.

The higher exposed picture will have a blown-out sky, but more detail in the darker area, while the lower-exposed one will have a correctly exposed sky with the darker areas underexposed.

These pictures are then combined by taking the correctly exposed areas of each picture, i.e. the sky from the low-exposure picture and the shadows from the high-exposure one, giving you a single picture without over- or underexposed areas.

I don’t know about OpenCamera, but you should be able to select the size of the exposure bracket, meaning how much higher or lower the different pictures are exposed.

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

It really isn’t hard, and for me it’s quite meditative. Truing old wheels can be frustrating if the rim is in bad shape, but with new components it normally goes very smoothly.

Something I figured out way too late: get a good spoke key in the right size, not one of the universal ones. It makes truing so much more enjoyable if don’t have to grab onto the extra slots in the spoke key all the time.

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.

As a young child, I had a wooden board with a bunch of different light switches mounted to it. Nothing to tinker with, but I had a lot of fun with the physical sensation of switching them on and off. I think that’s all you can really ask for at that age.

Later on, I enjoyed taking the switches apart, figuring out how they work and using them in my electronics projects.

My point is, whatever you choose should be physically fun, even without understanding it. A few switches and maybe a blinking light can entertain a toddler for a long time. The tinkering can come later.
