Restrooms for sure, thankfully, but are there any hallways you know of, any restaurants, public venues you know of, etc?

I need to distinguish it from South Dakota "SD" in my spreadsheet because I'm having an SD card shipped to my South Dakota mailing address.

I've never made that mistake and I've never personally witnessed anyone else slip either, but surely someone somewhere has. Especially in the years before smartphones & atomic clocks existed, when we had to manually set all our clocks.

I know that's why they always make it happen on a Saturday night Sunday morning so for most people it won't affect their work or school schedule the next morning

but Sunday mornings aren't always schedule-free for everyone. Plenty of people go to work/church/obligations on Sunday mornings,

so surely there's a non-zero chance that some clock mistakes have happened on daylight savings time Sunday mornings.

Do YOU know anyone who's made that mistake?

I had a conversation on Lemmy about this recently which is the inspiration for my question. I hope this is the right community to be asking this question.

Added context:

Arguably, you’d need start-up cash in our current system to start a cashless community, but once it’s up and running, you technically can use bartering and maybe a handful of people with jobs outside that community to get anything else the community would need.

So, could people buy land/properly that is not currently that developed, in a territory/state with no property taxes, and just build up from there? The land could be put into a community trust as well, so it’s not something that could get sold down the line after the land already gets developed.

I feel the pros of the concept are that it could legitimizes many of the points online about a cashless society being possible. If the proof of concept works out for one community, that eventually grows to a town, then the concept could be tried in other places as well.

I think another benefit of the concept is that it’s not something that should require having to change the current outside system to functionally work. Whatever is produced in excess by the community can be sold externally with the funds entering back to the trust to spend on resources that community may not be able to produce on their own.

To me, as an outsider, I feel this would be a tangible and realistic way of even popularizing the concept of cashless society being possible. It would take time and investment for a project like that to get off the ground, but I think it would be a beneficial way for people that do see a cashless society as the future to really reap the immediate benefits of the concept, and show its something sustainable and even scalable.

TLDR (I’m very long-winded): this YT video took measurements of three different audio cables, including a 200€ one, and found differences where there should be none. My physics knowledge (and general consensus among the scientific community) says the measurements of the different cables should be identical or near-identical — or I am, at least, under that impression. My own measurements, because the channel does provide the files, confirm that the expensive 200€ cable does measure differently from the others. But surely something else must be causing this? Please help me find out what that is, Lemmy!

Below, I go into a little more detail and context, and I go through what I have tried, etc.; I tried splitting everything up into chunks to make it easier to read, but I was never good at being succinct. Sorry about that 😬 :P

Context: What Am I Talking About?

Firstly, I should clarify that this isn’t relevant to most people, only really physics and audio-technology nerds. But I’m desperate. This question has been tormenting me for days...

I should provide some context. For some reason, YouTube gave me a rather odd video suggestion. I am very interested in audio technology, mixing, and mastering, but I’m not a snake-oil audiophile type. I guess you could call me a lover-of-audio, e.g., audiophile, but I don’t attach myself to that community. So you can imagine my confusion when this video was suggested to me on YouTube.

For anyone unwilling to click on an ambiguous YT link like that, here is a brief description: audiophile guy (who believes that cables affect sound) compares three cables, two of which are "cheap" (e.g., approx. 50€) and one of which is expensive (like 200€ — for a cable). His conclusion is ultimately (yes, I watched that far) that they don’t really affect sound, because they’re just interconnects (so RCA cables), and not speaker or power cables. But he actually records each cable and provides those music files — which means I can compare them as well...

By "records each cable," I mean that he used each cable to connect a CD-player to a pre-amp (for some reason) and then an analogue-to-digital convert (ADC) into his computer, where he can record the output; this way he gets just the supposed difference the cables make. I realize that the CD-player might have some inconsistencies, since CDs are a moving medium, but jitter compensation and stuff like that is very advanced these days, so this is getting pretty close to an accurate measurement of the cables, I think (correct me if I’m wrong!).

In the video, this guys claims that the measurements show a difference between the cables. This debate around cables is something I thought was quite contested, so I naturally decided to download the tracks (which he provides in the description) and compare them myself. Here’s what happened.

My Own Testing: They Don’t Null

So I downloaded his recordings, phase-aligned (which they weren’t already) everything and normalized to peak (which, again, was necessary, and creates the lowest delta compared to LUFS, etc.), and then null-tested. That means I inverted the phase of one, played two of the files at the same time, and thus got the delta between them.

The Mogami and Belden cables (the cheap ones) are nearly identical; there is a slight difference in the null-test, but it is statistically small enough, that I attribute it to measurement inconsistency (e.g., CD-player, DAC, or ADC performance, but also maybe natural conditions, etc.). I especially suspect — given that most differences occur at higher frequencies but aren’t really audible when listening — a jitter related issue, causing the timing to be just a little off, thus creating a delta in the higher frequencies. This could be due to the CD-player, but I have no idea.

...the Neotech (the expensive one), however, is significantly different.

---

Firstly, he provides the file for the Neotech cable with a significant phase delay compared to the others, of about 50 ms, and it is also about 0.02 db louder than the others. This alone makes it sound better, but when I correct this volume and phase difference — it still sounds better, and the null-test confirms that it is still quite different (we're talking differences up to -40 db here, which should definitely be audible).

It turns out, the volume difference actually changes throughout the song; meaning that in some places the difference is 0.01 db, and in others 0.03 db. But I can correct for that! I don’t know why it happens (someone smarter than me, please explain), but I can correct for it... And yet, the null test still shows a clear difference (especially when the singer makes s-sounds, i.e., sibilance).

Please Help Me

What is going on? My physics knowledge tells me this should be impossible. I can only imagine that for some reason the Neotech is more conductive, or something like that, and therefore recreates the harsh and very fast dynamics of sibilance more accurately. But the difference in conductivity should not be enough to cause that... I really am confused. Someone with more expertise please explain this!

For context, I cannot blind test ABX the Neotech. This is very subtle stuff here. But the null test shows differences as high as -45 db when the singer does those s-sounds and everything has been normalized. So clearly something is happening (and again, this is phase aligned and normalized and everything). So what could it possibly be?

Lemmy, please show me what I have missed! Show me the obvious error I or the video creator made. Sorry to make such a long post on c/asklemmy, but I don’t know where else to ask.

Like that thing where you hedge a point you're trying to make by acknowledging a weakness you're cognizant of that you still feel doesnt overly compromise your position?

Every phone I've ever bought in the past I've bought from Verizon store and the cost is always egregiouy extortionate. I know there is a less expensive way. Please tell me.

How to be sure the second-hand phone is in good shape & functional & legal & not stolen/ resold by criminals etc?

Update: Thanks y'all! I made my selection & purchase through Swappa. You made a girl happy today.

When "K" is in the process of texting someone and he's typing but he doesn't submit it and he doesn't delete it either, he just leaves it hanging as a draft as he goes on with his day, will the other person keep seeing these undulating "K is typing" dots forever? Or will the dots disappear if K doesn't submit the text?

I've been taking pics & vids with my smartphone for years but I'm tired of it telling me the memory is full. I want to have a dedicated camera that can upload to clouds, youtube, share via email, text etc. Anybody out there know about cameras?

Would their oath be null and void? Would they have to be sworn in again on a new book?

...meanwhile hundreds of school shootings & people die from gun mishaps every year but guns are still legal for almost any American to own?

The Caucasus or Caucasia is a region spanning Eastern Europe and Western Asia, situated between the Black Sea and the Caspian Sea.

Why are all white people called "Caucasians?" I don't even need to do any research to confidently say that the majority of white people on the planet have no affiliation or heritage links with that place whatsoever.

Granted there is an alternate definition for the word "caucus" which is a political word originating in the United states in the 1700s by white men in political gathering discussion groups, so perhaps that's how it got started. https://en.m.wikipedia.org/wiki/Caucus

Holland is such a pretty word, evoking imagery of tulips & wooden klompen shoes & windmills. Why aren't we allowed to say "Holland" anymore?

Imagine the behavioral response of a primal lawless bloodthirsty tribal person who gets apprehended & incarcerated into one of our prisons 😳

I find that coffee wakes me up way better than energy drinks, even when there is more caffeine in the energy drink, and the effects also seem to last longer. Is that a thing people can experience? Or is something wrong with me and/or I'm imagining it?

If a programming language is Turing complete, it means that you can write any algorithm in it and basically do everything that the computer is capable of doing, barring things like the process not having the privilege to access the APIs for doing something.

Is there an equivalent concept in language languages? Something like the ability to write down instructions for doing everything a human can do?

I was reading about the history of the paper clip and was thinking about butterfly-style paper clips and their history. Does anyone know when and where they were created or any other details?

I know novelty shaped paperclips are a thing but I've seen this design produced by different companies which makes me think it isn't a novelty thing.

When searching for it online I either get product pages or hair clips.

In places where GPS isn't available, in an underground transit station for example, it really seems like a no brainer to just use the cell towers in range to triangulate your location.

The police can already track the location of your phone using cell towers. That's how 911 knows where you are when you call them (AFAIK). Why isn't it just available for the phone itself to figure out its own location so you can use it to navigate?

I see a lot of communities hosted on hexbear.net on trending but when I click the link it says there's nothing there. Why is this the case? I'm using the Voyager app, but I' not sure if that has anything to do with it. Is there a way to make them visible?
