There’s no way to make a backdoor for encryption that keeps the encryption secure. Politicians and government flunkies can’t seem to wrap their pea brains around that concept.

The longevity of concrete isn’t just tied to the cylinder break strength.
Also, concrete with certain aggregates end up creating silica gel, which is bad for concrete.
Microwaves can cause water to become super heated and explosive upon touch.

In german and english, the comma in numbers is swapped. So the number 123.45 in german would be written as 123,45 while ironically, the thing that we used to separate thousands from hundreds is also swapped. So one-thousand-four-hundred would be written as 1,400 in english but as 1.400 in german …

On top of that, you would pronounce 678 as six-hundred-seven-ty-eight in english … guess what it is in german:
Sechs-hundert-acht-und-sieb-zig (literally six-hundred-eight-and-seven-ty)
i’m actually trying to change this point specifically because it irks me … but i am sadly alone with it.

The “magical formula” for stairs.
If this rule isn’t followed when building stairs, then it feels uncomfortable and more accidents will actually happen there.
In easy terms, it says: 2x riser + tread = average step lenght, usually 63cm.

Oh man I hate it when stairs are not built to the proper ratio. It feels so weird.
- 9 hours
I’m curious how this compares to eras before this formula was normalized and if this is universal or more so just a matter of keeping things the same so people get used to them.

I know of a few cases in religious buildings where stairs were designed to have a mystical effect. In Angkor Wat, for example, the stairs have a steep and tall tread pattern. Commoners weren’t used to them so they’d be exhausted, but the local monks were used to them so they could ascend and descend with ease.

Visit any old city in the UK (York and Edinburgh for example) and a lot of passages between streets have steps with uneven heights.
When you’re expecting it, its fine, you take extra care. But when its a modern building and they’ve fucked it up you really notice

My house is over 100 years old and all the damn stairs are different.
Jay@lemmy.caEnglish
7 hoursSame here. My stairs seemed to be an afterthought meant to squeeze in where it shouldn’t, built by someone who shouldn’t even been allowed to hold a hammer. I have size 13 feet, they hang several inches over the step when I use them. I’ve went down those stairs faster than intended a few times now. The basement stairs were even worse, but they’ve been replaced now.

I mean, did the seller specifically tell you it wasn’t caused by the stairs? They might have just managed to drag themself to the living room before expiring!

Hundreds of years of burning coal has spread mercury compounds all over the land, so that quite often when they build a new dam for hydroelectric power it’s dissolved into the water and ends up concentrated in fishes that people eat.
- HubertManne@piefed.socialEnglish2 hours
having to be careful about how much fish you eat due to mercury is one of the top dystopian things to me. People think about agriculture and grains with civilization but when you look at how important and common fish was to our diet for so long. Its crazy.

An example from my field of expertise: Mixing different kinds of metals in wet environments causes the less noble one to corrode.
