You can loosely think of hydraulics like pulleys, whatever ratio of input to output power you create is accompanied by a reduction in distance moved.

So a weight of 1kg on an area of 1sqm could balance a weight of 10kg on an area of 10sqm, but moving the 1kg would only generate 1m of travel for every 10m of movement applied.

If you try and displace 1sqm by 10m, you are displacing 10 cubic metres. If you use that displacement to move an area 10x the size, it need only move 1/10 of the distance i.e. 1 metre

You need to keep adding weight (force) to achieve the movement. The initial weight will only balance the system.

I assume that the comic is about breaking apart the mountain, you don't have to move far at all to achieve destruction. You also need a watertight system.

Climatic analogs for some US urban areas in the late 21st century:

Thanks, this is interesting

For anyone who is not going to read the article, the map shows what locations have the climate today, that the major city will have in 2080, under a variety of climate change scenarios

"Climates of most urban areas in the central and western U.S. will become most similar to contemporary climates found to the south or southeast (Fig. 2). Put another way, by the 2080s climate of cities in the northeast will tend to feel more like the humid subtropical climates typical of parts of the Midwest or southeastern U.S. today (warmer and wetter in all seasons, Supplementary Figure 2), whereas the climates of western cities are expected to become more like those of the desert Southwest or southern California (warmer in all seasons, with changes in the amount and seasonal distribution of precipitation, Supplementary Figure 3)."

Is F-droid insecure?

Your options are building from source, downloading dev apks, or using an app store. If you can't trust anyone, then you need to build from source

Fdroid is the best of the app stores, they are always trying to stay ahead of the curve when it comes to privacy, security, and trust

Reproducible builds are the standard for FOSS trust, see this article for an overview. They close the gap between app stores and dev apks

Fdroid are constantly working to increase the prevalence of reproducible builds, and to enable you to verify more so you have to rely less on trust
