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.

all of you refuse to face

Stop assuming.

Can I materialise just enough to move objects? Then I'd be hiding people's keys, unpairing their socks, moving furnitures ever so slightly to screw with their muscle memory, playing with their cats 3AM. Stuff like this, just for funzies.

Most things people mentioned here, plus: the ability to buy separated components with different specs, and build your smartphone at home. Like a PC.

(I'm aware this will probably never happen.)

why isn’t there H₂O₂

Because the undergrads used it for acetone peroxide.

I had to websearch this so might as well share it here: 6DOF = six degrees of freedom. You can move and rotate in all three dimensions.

Accurate for Descent. I played this game as a kid. At the start I hated it, because unlike Doom you need to aim vertically (Doom has three degrees of freedom: X axis, Y axis, rotation). But eventually it grew on me, it's like going from stale bread to a buttered toast - harder but nicer.

More like both talking at the same time. In a huge cacophony.

What’s profitable about losing sales of adult games?

From Visa/MC's PoV the situation looks like this:

  1. force itch.io - lose sales associated with that content
  2. leave itch.io alone - lose sales associated with anyone who takes Collective Shout's noise seriously, while Collective Shout starts smearing shit on Visa/MC by saying "they finance rape!"

Visa/MC likely determined #2 to be more than #1. In other words it's more profitable to do #1 instead.

Also, what leverage do these groups have over banks and payment processors? [...] I just don’t get it. Some random group in Australia has leverage over Visa and MasterCard - American companies - is that what we’re saying here?

It's mostly their ability to cause brand damage (reasons people avoid your brand because they see it negatively - like #2).

Visa and MC know that, when it comes to sex, people become really irrational. They take insane troll logic seriously, even if they wouldn't otherwise; and those religious groups like Collective Shout are really good at weaponising that irrationality. The way those alt right groups work is that you don't even need to know about the group to repeat their talking points, and spread support to those talking points.

I think you might have too much faith in government.

I don't. I'm picking the lesser of two evils here: a government is less worse than those megacorporations.

But ironically, I think YouTube and many other platforms quietly accept that if we want to live in a somewhat harmonious society, we can’t leave it to the government to make all the rules. (eg. YouTube banning vaccine misinformation and disinformation during a public health emergency.)

They didn't ban vaccine misinformation "because it's misinformation" or "because society would be better without it" (even if both things are true). Truth and morality doesn't matter for those platforms; what matters is brand damage.

but there’s a lot of lawful content that is really undesirable (scams, spam, deepfakes, hate speech, etc.)

  • scam - AFAIK already illegal in most of the world.
  • spam - should be illegal, at least in the most egregious forms.
  • deepfakes - it depends a lot on what is being done with the deepfake in question; plenty of them (like non-consensual sexualisation of someone) are either illegal or should be.
  • hate speech - it targets the dignity, well-being and often the lives of marginalised groups. Should be illegal.

Are you noticing the pattern? Those are things that should be handled by a government in defence of the public interest of everyone, not by a platform in defence of private interest of its shareholders. Even if a population has weak control over its government, it's more than it has over a corporation.

The law isn’t fast or flexible enough to keep up and every country has different (or laughable) definitions of some of these things.

This problem is not a good reason to create an even bigger problem. Like the one we're seeing - private interest dictating what should be allowed or not in the public sphere.

And, seriously, if the problem was just porn who would give a fuck. (Okay, some people would, some wouldn't.) The problem is that those corporations will happily target any group, any interest, any person, as soon as they deem profitable; because they have the power to do so, so porn is in this context only the canary of the mine. And this power needs to be curtailed.


But let's say, for the sake of argument, that implementing such a wide law would be unviable. Well, focus on financial service providers then - banks, payment processors, and the likes. Problem solved.

If forced to leave my homeland, Uruguay. More specifically Montevideo - large southern cone city like mine, so I can keep my life pretty much the same.

If allowed to zig-zag between the new country and the current one (southern parts of Brazil): either Italy or Slovenia. Probably Italy given I speak Italian. I can get two winters and autumns per year!

Facts first:

  • Lions can hybridise with tigers.
  • Tigers can hybridise with leopards.
  • Leopards can hybridise with pumas.
  • Pumas are closer relatives to domestic cats than ocelots.
  • Domestic cats can hybridise with ocelots.
  • Some feline hybrids are fertile.

Now, I don't know if viable or not, but I really want people to breed lion manes all the way into the domestic cat species. Why should I get a maine coon, if I could get a mane coon instead???

 

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:
