Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

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?

My guess would be this is one of the few major bots that ramp up its posting during Prime Times. I've been trying to use the fediversee for almost a year now and I check post multiple times a day, everyday. The vast, and I mean upwards of 90% or more of the post in my feed are just repost bots from Reddit or news aggregator bots. I'd be surprised if more than 10% of the post generated come from actual humans. I'm sure some of the server owners could give us much more insight on this with post by IP statistics. But my guest regardless is human interaction is pretty low.

[–] teft@lemmy.world 40 points 6 months ago (1 children)

Turn off bots in your profile and then ban the two or three bots that aren’t marked as bots and your feed will improve immensely. I forget that there even are bots on this site until someone mentions it in a comment.

[–] QuarterSwede@lemmy.world 5 points 6 months ago

I come more for the commentary not the source honestly.

[–] SorteKanin@feddit.dk 14 points 6 months ago

You can just block bot users when you see them. In my experience, it's not a big problem.

I have the opposite impression, that's interesting

[–] moosetwin@lemmy.dbzer0.com 2 points 6 months ago

If you check posts that have low upvote amounts, (say 0 - 20) you are more likely to see this phenomenon, especially in the technology communities.

[–] Appoxo@lemmy.dbzer0.com 12 points 6 months ago (1 children)

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.

[–] Jourei@lemm.ee 11 points 6 months ago

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

We need to turn it off and on again.

Fun fact for anyone reading who doesn't know: if you're ever in the room while someone is being defibrilated, make sure you're not touching them in any way. The electrical shock can stop your heart too!

My department only does this to brains though.

[–] CarbonatedPastaSauce@lemmy.world 9 points 6 months ago (1 children)

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?

[–] GorgeousWalrus@feddit.de 5 points 6 months ago* (last edited 6 months ago)

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

Called "sympathy asystole"

I will go get the AED. Keep Doing compressions till I return.

[–] Molten_Moron@lemmings.world 10 points 6 months ago (1 children)

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.

[–] Moops@lemmy.world 9 points 6 months ago* (last edited 6 months ago)

Shit, we forgot to call EMS didn't we?

[–] Nurse_Robot@lemmy.world 4 points 6 months ago (1 children)
[–] jws_shadotak@sh.itjust.works 4 points 6 months ago (1 children)

It looks like a mix of both, but the widened QRS complexes are what I'm going off of.

[–] Nurse_Robot@lemmy.world 7 points 6 months ago (1 children)

I suppose the treatment is the same. I'll start compressions if you don't mind getting the defibrillator and drawing up some epi

[–] jws_shadotak@sh.itjust.works 2 points 6 months ago* (last edited 6 months ago)

I'll take care of compressions

Let's flatten that curve!!

Like, more users and all over the globe I mean.

[–] A_Random_Idiot@lemmy.world 4 points 6 months ago (1 children)

mom?

Most online services experience this.

[–] umbrella@lemmy.ml 8 points 6 months ago

aww its kinda cute

[–] snooggums@midwest.social 8 points 6 months ago

This is neat to see, and also the case for every website and online game.

[–] moosetwin@lemmy.dbzer0.com 5 points 6 months ago

most games do too, unless you're TF2

rhymes on a dime

[–] PrinceWith999Enemies@lemmy.world -2 points 6 months ago (1 children)

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.

[–] TheOctonaut@mander.xyz 2 points 6 months ago (1 children)

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.

[–] PrinceWith999Enemies@lemmy.world 0 points 6 months ago

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.
