Most users are in US or western Europe timezones I would guess.
Although you could say the whole planet has a bit of a heart beat. Surely there are fewer people awake when the Pacific ocean faces the sun?
the whole planet has a bit of a heart beat.
Definitely a high presence of US users and the occassional (western) European among all.
Most of the times they represent themselve through their instance.But it’s the same as with Reddit: Mentioning a thing without mentioning a country = US.
Ah, my favorite way of trolling when I felt like it. Dispute something and eventually go “Ah, sorry didn’t know you were US specific with this” when I finally learn the revelation.
Based on that EKG, the fediverse is in some sort of v-tach and blood is not pumping efficiently enough to have a pulse

I always wondered what they use for ground when they are zapping people. Does it just go to the bed frame and out the ground wire the bed is plugged into?
There is no „ground“ in that sense. For a current to flow, you have to create a connection between the source anode and kathode (e.g. + and - of a battery).
You can think of the defibrillator as a battery with a very small but powerful charge. You close the circle by touching both pads to the body. The current will flow through one pad into the body, through the heart and „restart“ it and from there into the other pad. No current leaves this system (=goes into „ground“), it goes back into the defibrillator where the loop is closed.
Why do you get a shock from touching a power cable then, you ask? Without touching another pole and thereby closing the circle? (Note: power cables are AC but for simplification, above DC example can be applied)
This is because for our power stations, the ground is acting as a pole, the current can flow through the ground back to it and thereby close the loop. Therefore, you can reduce the risk of a shock by using boots with thick rubber soles - the rubber acts as an insulator.
Btw, „ground“ is an often misunderstood term. Voltage is the difference between the electric potential of two points in a system. What is often called ground, is the common reference potential.
As powerlines use the actual ground as reference potential, „ground“ has become the defacto name for that - but it’s just a point of reference and can be of any potential. I could measure a voltage (=difference) between the ground of two different systems

Nah. Defibrillators use direct current. Unless they are covered in salt water, there is no reason for the electricity to go anywhere other than in a relatively straight line
If you have two resistors in parallel the current doesn’t just flow through one resistor. You will get shocked. That’s why you yell “clear” before juicing them.
No. You yell clear before defibrillation because of hypothetical risk. The likelihood that a person actually received a significant shock is tremendously low, and even lower if they are wearing gloves.
As a side note, you do not yell clear before juicing them. You charge the defibrillator while continuing to give cpr, and then once it is charged, you clear, analyse the rhythm, and if it is shockable, ensure everyone is clear and deliver the shock. This protocol is to minimise the amount of time the arrested patient goes without chest compressions.

Don’t upvote bad information, people.
Electricity doesn’t immediately know where to go. It is true that it will always take the shortest path to ground, as soon as it finds that route. This is extremely simplified.

It’s shockable.
I will go get the AED. Keep Doing compressions till I return.
Dude it’s been 3 hours, where did you go for that AED? I don’t mind continuing compressions, but my lips are really getting chapped.
Shit, we forgot to call EMS didn’t we?
Looks more like v fib
It looks like a mix of both, but the widened QRS complexes are what I’m going off of.
I suppose the treatment is the same. I’ll start compressions if you don’t mind getting the defibrillator and drawing up some epi
I’ll take care of compressions
Let’s flatten that curve!!
Like, more users and all over the globe I mean.
Let’s flatten that curve!!

Most online services experience this.
aww its kinda cute
This is neat to see, and also the case for every website and online game.
most games do too, unless you’re TF2
rhymes on a dime

This is seasonality.
Seasonality is a characteristic of a time series and refers to periodic and generally regular and predictable changes that occur over a year.
To make it more generic, drop the “over a year” and just refer to the periodic signal over time idea. You can find additional signals by how you bin the data, eg monthly or day of week.
Seasonality specifically refers to periodic signals over the course of a year. Any other interval means it’s not seasonality. You can read that yourself in the definition you quoted.
I do this for a living. Seasonality as a generic term refers to temporally periodic signals but can even be extended to talk about non-temporal aspects of a signal. The same math used in areas like econometrics to remove periodicity in annual data can be applied to multiple domains. The main motivation to removing or isolating periodicity is to allow for investigation into the underlying phenomena, or to allow the investigation of the sources of periodicity independently of other drivers. In every case, though, seasonality is an acceptable term in everything I’ve written, read, and worked on.
