Yes to both questions. The video is copied to multiple drives on multiple computers in multiple locations. But even if it was only on one drive, a single server can serve multiple users simultaneously.

Every house & apartment should have a sink plunger and a toilet plunger.

My easy fix solution is to regularly! pour vinegar and bicarbonate soda down all my drains, including the shower. Let it sit for 5 minutes, then follow with hot water- not boiling as it can crack porcelain. I think I’ve only used my plunger once. My dad was a plumber. Got plenty of tricks of the trade from him.

It's not confirmation bias. They literally do have to deal with a drain full of concentrated flesh-eating chemicals.

Reply to ELI5: How is QUANTUM superposition mathematically/ontologically possible? Physics ELI5: How is superposition mathematically/ontologically possible? Physics by Forward-Razzmatazz18
Before we talk about what a superposition is, let's talk about where it comes from namely the field of quantum mechanics. In quantom mechanics, outcomes are probably stick rather than deterministic as they are in Newtonian mechanics.
So what the heck did I just say? In Newtonian mechanics, we know exactly what the outcome of an event will be, we just need to calculate for the variables involved. When I throw a ball up in the air, we can predict exactly how high it will go, where it will land, and how fast it be going when it does.
Quantom mechanics is very different. In a quantum mechanical system, the exact outcome of an event is unknown. Using a model that is commonly discussed known as the double slit experiment as an example, when we fire a particle at the double slit we don't know where the particle will land. Instead, what we know are the probabilities of the particle landing at any particular location. There is no guarantee where the particle will land, and every time we repeat the experiment there will be a different result ( more accurately the results will all fall within one of the expected possible outcomes, not that there will be a unique outcome for each individual experiment). This feature is at the very crux of what it means to be a quantum mechanical system. Now, quantom mechanics is very weird (VERY weird), and certain conditions such as observation can cause "the wave function to collapse" ( this is a reference to the Schrodinger wave function, the equation that is used to calculate the probabilities of certain events in a Quantum system) and a quantom system reverts back to a classical/Newtowian system.
Okay, so back to your question. What is a superposition? Well the simplest answer to that is that a superposition is what we call an event that is still in the probabilistic (ie undetermined) state. A superposition is what exists before a pesky observer gets curious and causes the wave function to collapse. A superposition, by definition, means multiple outcomes are possible and undetermined. How is it possible? Well, it's possible because it makes accurate predictions about the world around us. Superpositions are not just a thought experiment, they're not some theoretical abstract concept that only makes sense on paper. The Schrodinger wave function makes many predictable, measurable, verifiable predictions about particle interactions and is arguably at the very heart if what makes all chemistry work.

The high level company goals are not going to change, though, especially at a publicly traded company. Regardless of the adversity through the year, the goal will still be to make money. A business trying to lose as little money as possible instead of trying to make money will have some big changes coming.

Reply to eli5 Interest is confusing by maddskate
Tim needs to borrow $200 from me, and he wants to pay me back in a month. I don't get anything out of it so I say no. So Tim sweetens the deal, says he'll pay back the $200 plus 10% interest ($20). So I say yes to the deal. The 10% is interest.

It’s far from being the sole role of a government. And I wouldn’t be able to confidently say that teens and younger are fully aware of all of the physiological mechanisms and consequences of alcohol and tobacco consumption and addiction.

If it’s Capex then who cares. If it’s opex it’s better to be on the right side of the coin. Large organizations should require their leaderships to work in FP&A for a quarter. It would eliminate a lot of these types of questions.

Reply to ELI5: How is QUANTUM superposition mathematically/ontologically possible? Physics ELI5: How is superposition mathematically/ontologically possible? Physics by Forward-Razzmatazz18
It's possible because it isn't impossible. There is no rule in physics or math that says it is impossible, which means it's possible.
And what it is, is basically saying that some subatomic particles can exist in different states at once.
For example, electrons have a property known as spin. Since they have spin they have direction (kind of like how the Earth spins and because of that, has a north and south pole). Since electrons have a direction, an electron can be "up" or "down."
Superposition says its possible for an electron to be put into a state where it is both up and down at the same time, and will only definitely be one (and not the other) when it interacts with another particle.

Couldn’t that logic apply to other harmful substances though? Meth. Cocaine. Heroin. There’s a black market for all of those.

Botulism. Not a big deal for the average person, but potentially dangerous for infants, and anyone else with a suppressed immune system (including most people medicated for autoimmune diseases).

I'd put it more akin to a survivor bias. The issue stems not from them only looking for evidence supporting their opinion, but them not encountering a fair sample. They only see the drain cleaner "survivors", never those that got unclogged.
