I'll go first

I think it would be good for the community and people in the US to have ways to make sure they’re not creating relationships with ICE agents. If the community doesn’t want it all good. and obviously not meant to profile people.

1. Obviously we know some names of agents who have murdered people: Jonathan Ross, Brian Palacios, Jesus Ochoa, Raymundo Gutierrez
2. I presume they’d be pretty conservative and machismo. Maybe have some blue lives stickers on their truck.
3. Maybe tattoos, specifically Punisher. Could be police also.

What else could you use to sniff out if somebody is ICE if they’re hiding it from you?

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!

Edit: see this and this other excellent comment.

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. That is rather suspicious on his part. 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.~~ (edit: crossed out because this is a little too ridiculous) 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. I cannot hear any difference whatsoever. This is very subtle stuff here. But I can see a difference, 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?

Edit: here, for clarity, screenshots of the null test at different moments in the tracks from the youtube vid (here nulling between the magomi and neotech).

Normal part of song, no sibilance or cymbals, but otherwise singing, piano, bass guitar, drums, etc.:

When the singer creates sibilance with an s-sound:

The null test was performed in the Reaper DAW with Voxengo SPAM and Reaper’s built-in phase align, normalization, and phase inversion.

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.

No, I'm really interested.

I have Schizophrenia and would like to know if sound I hear is real or just normal background sound using a app. Thanks

I’ve recently started a subreddit (yes I know reddit sucks I am aware) and an associated Discord to experiment with a simple idea, can social media be used to coordinate productive labor outside of market relations, where people work together to produce useful things directly for use, rather than for profit, wages, or exchange.

The experiment is just getting started, but I’m interested in seeing how far this type of coordination could go. We already use social media for organizing activity without the market, from birthday parties to protests, why not production? But anyway back to my question.

Recent events with Discord, where personal data is required in ways that make hosting experimental communities risky, have highlighted the need for a more secure, less corporate platforms for this type of social experimentation.

I’m curious if anyone here has experience with alternative platforms that could host this kind of collaborative, post-capitalist project safely? Any suggestions would be greatly appreciated.

Middle click failure plagues nearly every mouse I've owned, OEM, Logitech, wired, or wireless. I take full advantage of the middle click shortcuts like opening links in new tabs, but I don't think I'm putting it through undue stress either. As far as I can tell, I'm clicking it with the same force as I would the other mouse buttons and much less frequently than the left click.

Failure usually starts with occasional missed middle clicks, which after some point, rapidly progresses until it's failing to register more often than not. At that point, everything else will still work perfectly. No improvement even if I take it apart to clean out what little dirt had accumulated.

One of my mice has managed to avoid this fate far longer than the others but I've just recently stopped using it due to the rubberized exterior turning all gooey and sticky. The only middle mouse buttons that seem immune to all of this are the ones on ThinkPads. Anyone else notice this or could recommend a good mouse that can stand up to a bit of middle-clicking?

I am looking to buy a new phone and this time around, I want to get a refurbished to save money. I wanted to know what's the best site/place to buy refurbished that you recommend?

[All these points apply to sex and to gender, so for ease of reading, I'll just discuss gender]

Gender-exclusive groups are common in many societies, such as men-only and women-only social clubs and casual activity groups like a men's bowling group or a women's reading circle.

Sometimes this is de-facto, but sometimes this is enforced by rules or expectations, treating the club as a safe space for airing issues people have with other genders, or avoiding perceived problems with other genders.

I came across this old comment in a garbage subreddit by accident when researching. The topic is Men's Sheds:

"Here's the thing. No reasonable person has an issue with women having their own women's activity groups. The annoying part is that whenever men try to do something similar, that's a problem. Women either want them banished or demand entry, EVERY time."

I think their claim is nonsense, grossly exaggerated at best. I also know of many counterexamples of men trying to get into women-only groups (as an extreme case, the Ladies Lounge of the Mona art gallery in Australia was taken to court for sex discrimination, with the creator claiming they would circumvent the ruling by installing a toilet). But nonetheless, I can understand why they feel this way, patriarchal social relations change how most people see men-exclusive spaces vs. women-exclusive spaces.

But my response to their claim is that, I am reasonable and I do have an issue with any group setting up places which discriminate based on gender. These safe places can form as a legitimate rudimentary form of protection, yes, but they maintain and often even promote sexism, and should all be challenged and turned into something better which serves the same purpose.

Of course, I'm limited by my own experiences and perspective, so I'd love to hear your opinions on the topic.

A coworker who was the reason why I was moved to another department (she is friends with the manager) changed departments herself and now I sometimes have to work with her.

First time she saw me at her new position she greeted me as nothing happened, as she wasn’t the reason why I was moved laterally. I replied with a non effusive hi.

I don’t engage in non job related conversations with her, if I have to work with her I just ask her in a neutral voice where is what I need and proceed to do my job. Otherwise I avoid her because I don’t trust her. I don't have to work with her whole shifts or every day, which is good.

The incident I mentioned on my first paragraph happened 2 years ago and I still remember it enough not to like that person. I don’t know if more mature folks would have already forgotten about it but I cannot. Am I holding an unhealthy grudge? I mean I’m happy if I don’t have to see her.

I am sure if it was some 9-5s name in that file they would have been executed by now .

I need to find an adapter for this stupid HD-DVD drive from 2008. Sorry, this is before my time.

What would be the less shameful reason why you would have to be detained overnight?

I have been working as a software developer for PwC for couple of years, but recently I am being asked to sign an NDA - regarding not sharing information about any company including but not limited to clients or for advantage in securities transactions. I do not interact with clients or their information directly.

Does such NDA mean I am not allowed to buy/sell shares for this company in future?

Not sure if this is the right community for this.

I want to create games. How could i do that?
