Is there some story behind PPB? As in, why do you guys like that pic so much?

The missing piece is that hiding bad news should be harder. For example, if you're a researcher and all you claim from your research are the good news, people (and the ideal Bayesian agent) should immediately suspect "maybe they're hiding the bad news".

Hyde says that the problem is that, although scientific facts are taught at school, the facts "about" science are not taught well enough.

Bingo. They do a poor job teaching people:

  • That failures are not only expected, but welcome; they'll guide future successes.
  • That conflicts of interest do happen, and peer reviewing is a way to address them.
  • That the current leading theory on something is simply the current best explanation, not some immutable truth.
  • That science doesn't say "trust me"; it shows you the data, and asks you to find a better way to explain it.

We (people all around the world, I think?) also do a poor job at teaching ourselves basic rationality:

  • That you should get suspicious of any institution or group that only shows the good parts - they're likely hiding shit.
  • Why "trust me" is an insult towards the hearer's intelligence.
  • Why people shouldn't vomit certainty on things they cannot reliably know.

Ok have you personally taken responsibility for the fact that your media consumption has made your worldview delusional?

This is a loaded question on the same level as "did you stop beating your wife? Yes or no?".

But let's bite: yes.

I come from a scientific background. And you don't get to keep delusions about something when reality is making you interact with that thing over and over, regardless of the origin of said delusions. You face them, as soon as you step into the uni. And one of the things I often talk with people is how science is misrepresented in media, specially after that clown of the former president of my country started babbling about Ivermectin*.

And, due to the nature of the content of this community, I expect at least some of the other people in this comm to be in the same situation as me - to be from a scientific background (or even scientists themselves) and to try to spread awareness on how media misrepresents science, the scientific method, and scientists.

So your "all of you"? Bullshit.

Unless you're decontextualising the whole thing to talk about media-based delusions in general, even if the context screams "regarding science".

(Or perhaps you'll try to change goalposts and say something like "ackshyually, taking responsibility is something else lol lmao.)

Nope? Ok then I am not making an assumption,

Even if your assumption was true (it is not), it would be still an assumption. You're still vomiting certainty about something you cannot reliably know, such as what all individuals in a whole group of people do or don't.

I am stating human nature

I think that both of us know that you're bullshitting.

*just to point out another assumption you're voicing in your comment: "It is why we have a racist reality tv show actor as president". Why do you think everybody here is American?


EDIT: note this topic itself is already a way to take responsibility for all the crap media shows dressed as science. For a start:

what are LadyButterfly, Admetus, klemptor and me doing here, if not highlighting that media grossly oversimplifies Physics?

[–] lvxferre@mander.xyz 3 points 1 day ago

Yup, pretty much.

For me, an example of that not mentioned in the thread is Yahoo Answers. At least where I live people used Answers a fair bit; first for its intended purpose (Q&A), then to discuss random stuff, under pseudonyms.

But Yahoo never gave enough of a fuck to Answers. Instead the place festered with trolls (...like me, I know), people gaming the points system, and low quality content. Becoming emptier and emptier, until it was eventually closed down.

If Yahoo played its cards right, Quora would never exist, and Reddit would be forever stuck as "we just share links here", it wouldn't evolve into a forums-like, forums-killing platform. Lemmy would still pop up, I believe, but as an alternative to some Yahoo service geared towards discussion.

The social media company last week denied the allegations, calling them 'politically motivated.'

"We don't want some rogue fascists from the outside to meddle in our elections" is politically motivated, and there's nothing wrong with it.

So congrats for the Apartheid-born moron and his drones: you're correct and wrong at the same time.

Some users there are fairly decent, but their collective reputation is deserved due to how they behave outside their instance.

If Yahoo acquired either Google or Facebook, we would have probably forgotten about it. And instead something else would spawn on its place, and we'd be asking why Yahoo didn't buy that something else. [edit reason: grammar.]

He's still anxious about people mocking his hobbies, isn't he? And then suddenly they don't care, or rather they do care but for the good reasons.

I've been using SMB from the Linux side of the things and File Manager+ from the Android side. Both are things I'd already have even without that:

  • SMB - I have it since my mum had that old W7 laptop, so she can store her junk in my computer. (Her laptop had notoriously small disk space). Eventually its usage evolved into my main method to share files at home, specially with the TV box, so I can torrent full anime seasons and watch them from the TV.
  • File Manager Plus - because the Google one is rubbish, and this one has network access. That's it.

I might try some of those out though. Packet in special looks promising.

 

This infographic is still incomplete; I'm posting it here in the hope that I can get some feedback about it. It has three goals:

  1. To explain what federation is. No technobabble, just a simple analogy with houses and a neighbourhood.
  2. To explain why federation is good for users.
  3. [TODO] Specific info about the Fediverse, plus some really simple FAQ.

Criticism is welcome as long as constructive.

EDIT: OK, too much text. I'm clipping as much as I can.

 

This is not some sort of fancy new development, but it's such a classical experiment that it's always worth sharing IMO. Plus it's fun.

When you initially mix both solutions, nothing seems to happen. But once you wait a wee bit, the colour suddenly changes, from transparent to a dark blue.

There are a bunch of variations of this reaction, but they all boil down to the same things:

  • iodide - at the start of the reaction, it'll flip back and forth between iodide (I⁻) and triiodide ([I₃]⁻)
  • starch - it forms a complex with triiodide, with the dark blue colour you see in the video. But only with triiodide; iodide is left alone. So it's effectively an indicator for the triiodide here.
  • some reducing agent - NileRed used vitamin C (aka ascorbic acid; C₆H₈O₆), but it could be something like thiosulphate (S₂O₃²⁻) instead. The job of the reducing agent is to oxidise the triiodide back to iodide.
  • some oxidiser - here it's the hydrogen peroxide (H₂O₂) but it could be something like chlorate (ClO₃⁻) instead. Its main job is to oxidise the iodide to triiodide. You need more than enough oxidiser to be able to fully oxidise the reducing agent, plus a leftover.

"Wait a minute, why are there a reducing agent and an oxidiser, doing opposite things? They should cancel each other out!" - well, yes! However this does not happen instantaneously. And eventually the reducing agent will run dry (as long as there's enough oxidiser), the triiodide will pile up, react with the starch and you'll get the blue colour.

Here are simplified versions of the main reactions:

  1. 3I⁻ + H₂O₂ → [I₃]⁻ + 2OH⁻
  2. [I₃]⁻ + C₆H₈O₆ + 2H₂O → 3I⁻ + C₆H₆O₆ + 2H₃O⁺

(C₆H₆O₆ = dehydroascorbic acid) Eventually #2 stops happening because all vitamin C was consumed, so the triiodide piles up, reacts with the starch, and suddenly blue:

 

EDIT: @mindbleach@sh.itjust.works shared something that might help to circumvent this shit:

Contained in these parentheses is a zero-width joiner: (​)

Basically, add those to whatever you feel that might be filtered out, then remove the parentheses. The content inside the parentheses is invisible, but it screws with regex rules.

 

Changes highlighted in italics:

  1. Instance rules apply.
  2. [New] Be reasonable, constructive, and conductive to discussion.
  3. [Updated] Stay on-topic, specially for more divisive subjects. Avoid unnecessarily mentioning topics and individuals prone to derail the discussion.
  4. [Updated] Post sources whenever reasonable to do so. And when sharing links to paywalled content, provide either a short summary of the content or a freely accessible archive link.
  5. Avoid crack theories and pseudoscientific claims.
  6. Have fun!

What I'm looking for is constructive criticism for those rules. In special for the updated rule #3.

Thank you!

EDIT: feedback seems overwhelmingly positive, so I'm implementing the changes now. Feel free to use this thread for any sort of metadiscussion you want. Thank you all for the feedback!

 

Apparently humpback whale songs show a few features in common with human language; such as being culturally transmitted through social interactions between whales.

"The authors found that whale song showed the same key statistical properties present in all known human languages" - my guess is that the author talks about Zipf's Law, that applies to both phoneme frequency and word frequency in human languages.

[Dr. Garland] "Whale song is not a language; it lacks semantic meaning. It may be more reminiscent of human music, which also has this statistical structure, but lacks the expressive meaning found in language." - so while it is not language yet it's considerably closer to language than we'd expect, specially from non-primates.

Aue, patrue placentae! (Oi, tio do pavê!)

 

It's a 10m papyrus scroll from Herculaneum, one of the cities buried by Vesuvius' volcanic ash in 79 CE. It's fully carbonised but they're using a synchrotron to create a 3D model of the scroll without damaging it. Then they're using AI (pattern recognition AI, perhaps?) to detect signs of ink, so they can reconstruct the text itself.

The project lead Stephen Parson claims that they're confident that they "will be able to read pretty much the whole scroll in its entirety". And so far it seems to be a work of philosophy.

 

The title is a bit clickbaity but the article is interesting. Quick summary:

A new ancient population was recognised, based on genetic data. This population has been called the Caucasus-Lower Volga population, or "CLV". They were from 4500~3500BCE, tech-wise from the Copper Age, and lived in the steppes between the North Caucasus and the Lower Volga. .

About 80% of the Yamnaya population comes from those people; and at least 10% of the ancestry of Bronze Age central Anatolians, where Hittite was spoken, also comes from the CLV population. The hypothesis being raised is that the CLV population was composed of Early Proto-Indo-European speakers (the text calls it "Indo-Anatolian").

I'm sharing this pic because it might be useful, to advertise Lemmy in Reddit meme communities and the likes. It isn't supposed to be a full info dump, just to spread the word that Lemmy exists and give people some room to ask questions about it.

The copypasta is from @Blaze@lemmy.dbzer0.com. The meme is from @JokkaJukka@lemmy.world.

Here's the source SVG file in case anyone wants to edit it.


EDIT - @Libb@jlai.lu had a great take on this idea, I need to share it here:
