What Math Problems Are They Trying To Solve When Mining For Crypto?

There is a special function called a cryptographic hash. Basically it takes anything as input and produces a fixed-length output. For all intents and purposes here, you can basically treat the output as being random. Meaning you can’t predict what the output is going to be for any given input without simply trying.

For miners, the input is the block they want to add to the block chain, plus a magic number they get to come up with. They then combine the two and perform the cryptographic hash. What they’re looking for is for a output of the hash that has certain properties. For example, the hash (being a number) has 32 trailing zeros.

Was Deckard a Replicant in Blade Runner?

In the Theatrical cut the answer is left ambiguous. In the Director’s and Final cuts the answer is definitely yes. In the Theatrical cut most widely seen in the US there are still hints that Deckard might be a replicant which include:

  • The fact that there is no mention of, or questions asked about, Deckard’s life during the period between his (alleged) previous stint as a police officer and the events of the film. The only exception being the mention of a failed marriage early in the film.

Why Is There A Growing Number of People Voluntarily Disappearing In Japan?

No human in this world does anything without a reason. There is always a reason no matter what and in Japan (specifically Tokyo) there is a lot of reasons to just disappear. There is a ton of videos/articles about hikkomori, NEETs, and Jouhatsu which I believe is all related to other in the sense that people become/do these things because of a reason. Im gonna list a few reasons why people become Hikkikomori, NEET, or Jouhatsu:

How Does Rebar Strengthen Concrete?

rebar

Concrete is very strong in compression (loads trying to crush the concrete,) but very weak in tension (loads that try to pull the concrete apart,) and very weak in shear (loads that try to snap the concrete like how you’d break a twig in half.)

Steel is a linear elastic material that is basically equally strong in all directions – tension, compression, shear… has pretty much equal resistance to all of them.

Why Is Beef Jerky So Expensive?

why is beef jerky expensive

Jerky is expensive because whole cuts of beef are expensive. It seems even more expensive for jerky because the dehydration condenses the mass of the product, but when it is sold by the pound originally, all of the water weight is counted.

A pound of steak becomes a few ounces of beef jerky, and the few ounces of jerky need to cover the cost of the steak and energy required to evaporate all the water and add the tasty smoke.

How Did Germany Defeat France So Easily In WW2?

how did germany defeat france so easily in ww2

It was a combination of factors.

One thing that’s very overplayed is the Maginot Line; the line of fortifications that France built along its border with Germany. In the popular imagination people often say that the French sat behind the Maginot Line and the Germans went around it through Belgium, but that’s just completely false. The French in fact built the Maginot Line to force the Germans to go through Belgium. The French sent their best forces and tanks to Belgium when the Germans attacked.

But what happened is that the Germans took a big gamble that paid off. Belgium can be roughly divided into two parts:
