  Do you have a link to that study? I’d be interested to see what the false positive/negative rates were. Those are the big danger of LLMs being used, and why a trained doctor would be needed.

• ⁨Comment⁩ on ⁨Surprise! People don't want AI deciding who gets a kidney transplant and who dies or endures years of misery⁩ ⁨⁨13⁩ ⁨hours⁩ ago⁩:

  I believe a good doctor, properly focused, will outperform an AI. AI are also still prone to hallucinations, which is extremely bad in medicine. Where they win is against a tired, overworked doctor with too much on his plate.

  Where it is useful is as a supplement. An AI can put a lot of seemingly innocuous information together to spot more unusual problems. Rarer conditions can be missed, particularly if they share symptoms with more common problems. An AI that can flag possibilities for the doctor to investigate would be extremely useful.

  An AI diagnostic system is a tool for doctors to use, not a replacement.

  To an extent. You are still talking 20-40 degree windows, but triangulation is definitely possible. I’m not sure if it’s used like that however.

• ⁨Comment⁩ on ⁨Why most countries are struggling to shut down 2G.⁩ ⁨⁨1⁩ ⁨day⁩ ago⁩:

  5g is a lot more capable and flexible compared to older generations. The main one is a massive increase in capacity, for the same frequency allocations. Compounding with this is that it can be directional. This allows several phones to use the exact same channel simultaneously, so long as they are positioned at different angles to the tower.

  5g also uses more frequency bands, allowing even more data to be moved around. Unfortunately, 2g has most of the lower frequencies, higher frequencies carry more data, but have less penetration into buildings.

  Finally, 5g allows for priority and context awareness. E.g. the police can have their phones prioritised, or VoIP calls given priority over video streaming. It can also trade bandwidth for range. This allows a tower to either reach further to cover a larger area, or focus down, to provide more bandwidth locally.

  In theory 5g could have a similar range to 2g. However, that rarely happens. It requires it using the lower frequencies, that 2g currently uses, and well as dropping its data rate to improve range. Most of the time it’s optimised for shorter range, and more towers using higher frequencies. This gives impression of a far smaller range. But give a huge increase is available bandwidth.

  The load varies, though I’ve found the suspension is hard enough that it doesn’t shift for a normal load up. I mostly do it because I’ve noticed that, when I hit a bump, my lights can sweep up over the windows of cars in front.

  Also, I don’t mind them readjusting it. It’s calling it a fault that bugged me.

• ⁨Comment⁩ on ⁨FuckYourHeadlights - A community for people to organise and vent about ridiculously bright lights⁩ ⁨⁨3⁩ ⁨days⁩ ago⁩:

  I drive a van, so I could easily be the culprit. I therefore make a habit of adjusting my beam dip appropriately. Apparently that is unusual enough for them to note they had been adjusted in the service. There’s literally a dial on the dashboard. You’re SUPPOSED to adjust them to the vehicle and road conditions! Apparently not having them set to max is now considered a “fault” to fix!

• ⁨Comment⁩ on ⁨Nobody Wants a Nazi Electric Car⁩ ⁨⁨3⁩ ⁨days⁩ ago⁩:

  I would personally add a small amount of slack for bad taste satire (we were all young idiots at some point), but basically agree. Any signs of the other points, and that slack is gone, however.

  I was mostly curious if the OP was acting in bad faith, or a useful idiot that could be reasoned with.

• ⁨Comment⁩ on ⁨Nobody Wants a Nazi Electric Car⁩ ⁨⁨4⁩ ⁨days⁩ ago⁩:

  History doesn’t repeat itself, but it does rhyme. Musk isn’t a member of the Nazi party. He does hold a lot of important views in common with them, however. He also associates with people who fit most of the rest.

  What percentage do you think is needed before calling someone a Nazi?

• ⁨Comment⁩ on ⁨Women earn 78 cents for every $1 men paid on average.⁩ ⁨⁨4⁩ ⁨days⁩ ago⁩:

  The Simpson’s Paradox also comes into play here.

  It is perfectly possible for 1 group to be (apparently) discriminated in the bulk data, while the reverse is happening in individual data. E.g. a university showing a male bias overall, yet each department shows neutral, or even a female bias.

  This makes bulk patterns particularly troublesome to work with. Men and women want different things from work. Men are disproportionately discouraged from having a work life balance, while it’s far more acceptable for women to not maximise their earning potential.

  It works on frogs. The force is distributed over the whole body, so it’s no worse than gravity is on our bodies.

• ⁨Comment⁩ on ⁨Amazon Restricted Vaginal Health Products for Being ‘Potentially Embarrassing’⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I disagree. The human body is mostly water. Water is slightly diamagnetic. Therefore, a sufficiently strong magnet is capable of levitating a human body off the ground.

  Magnets can definitely have an effect, just not at puny neodymium magnet levels!

  Interestingly, some lights are set up to deliberately slow down speeders. If you are above the speed limit, they turn red, just to slow things back down. Unfortunately, most of the people involved never put cause and effect together.

• ⁨Comment⁩ on ⁨Woke turned to CRT then turned into DEI. Anymore acronyms they'd be the government⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  It’s always fun to try and get them to define “Woke”. When they can’t/won’t, you can default to deSantis courtroom definition. “the belief there are systemic injustices in American society and the need to address them”.

  While cognitive dissonance doesn’t work on the core supporters, the ‘passive’ supporters are still susceptible to it. Many support aspects of being “woke”. If you can get them to realise that then “anti woke” becomes a lot more repellant to them. Anti woke is effectively anti empathy.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  What is a particle, what is a wave? QM entities are neither. They are a 3rd thing. A quantised wave is the term my university professor used as a short hand. The nature of that wave is described by the Schroeder equation + its constraints. Certain interactions will bound it heavily, and so make it look particle like, others emphasise the wavelike properties.

  You require the maths to actually do anything useful with it, but not to get the basic concepts. It’s no different to the rest of physics, in that. E.g. you can understand the concepts of orbital mechanics, without being able to calculate them.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  While I’m rusty as hell, my physics degree was actually focused quite a lot into QM.

  It’s perfectly possible to get a reasonable understanding of what’s going on without going head first into the maths. There are definitely areas however that we don’t have a good conceptual model of yet. For those, the maths definitely leads the way. 90% of QM is comprehendible with relatively little maths. You only need the maths when you start to get predictive.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  QM entities are quantised waves. You can make a wave look very close to a particle quite easily, a particle can never behave like a wave.

  Dumping the mental short hand of particle interactions is one of the main reasons most people can’t get their heads around it.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  So why are you so upset with us trying to fix it?

  I personally find the anti science, anti learning crowd has gone from amusing, to annoying, to terrifying.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I disagree with it being hard to comprehend. The maths is an absolute bitch, but the basic premise is fairly simple. Everything is (quantised) waves. The rest clicks, once you get your brain to accept this. Everything else is a consequence. Those consequences can lead you down deep dark tunnels, filled with evil maths and mind bending results, but the basic idea is simple.

  I have a bit of an issue with memes that are actively misleading.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  That is part of what bugs me.

  Quantum mechanics isn’t magical or unknowable. It’s just an area of physics where some of our base assumptions/approximations break down. It’s not even that hard to wrap your head around, it just seems most people don’t want to try.

  So was “Donald Trump for president” and look at the damage that has caused.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Perception and observation are different things. Air molecules can be “observers” when looking at electrons etc.

• ⁨Comment⁩ on ⁨Observer⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  This sort of comic always bugs me. Observation in QM is not the same as observation in layman terms.

  Best think of it as hit it and watch the pieces fly. When you get small enough, you can’t approximate out the impacts. It’s akin to studying road traffic by sending an overloaded freight truck the wrong way and counting tires that hit the verge. It might also affect the current traffic’s motion.

• ⁨Comment⁩ on ⁨France runs fusion reactor for record 22 minutes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  That’s part of the reason a moon base could be viable. The sun outputs a reasonable amount of helium 3, which is great for fusion reactions. Unfortunately it tends to sit at the top of our atmosphere and get blown away again. On the moon, it gets captured by the dust in collectable quantities.

• ⁨Comment⁩ on ⁨France runs fusion reactor for record 22 minutes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I never said it wasn’t useful, just a very low efficiency reactor. Then again, if it was better, it would burn out faster, which would be bad for life on earth.

• ⁨Comment⁩ on ⁨France runs fusion reactor for record 22 minutes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Even the core only has an output of 200-300W/m^3.

• ⁨Comment⁩ on ⁨France runs fusion reactor for record 22 minutes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  The amusing thing is that the sun is actually quite a shit fusion reactor. It’s power per unit volume is tiny. It just makes it up in sheer volume. A solar level fusion reactor would be almost completely useless to us. Instead we need to go far beyond the sun’s output to just be viable.

  It’s like describing one of the mega mining dumper trucks as an “artificial mule”.

• ⁨Comment⁩ on ⁨Amazon's previous VP of Prime Gaming said they "tried everything" to disrupt Steam⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  It’s more than just pushing for support. They have made a lot of windows only games just work on Linux.

  They’ve changed it from “need to release and support Linux” to “zero effort other than not actively fuck up the compatibility layer”. In user land, it’s the same thing. For developers it’s a vast difference.

  IoT can be great. The key is, as you pointed out, to actually have personal control over it.

  It also has to account for WAF (wife acceptance factor). If it doesn’t fail gracefully to a dumb version of itself, it’s not to be trusted

• ⁨Comment⁩ on ⁨I feel my life is empty. Is there any way to stop this?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  It’s mostly a non issue in my group. Our ages run from late teens to OAP. I often don’t even notice ages. I just talk to them as a person with a shared interest.

  It does help that at least half of us are neurodiverse. Most awkwardness doesn’t even get noticed by either side. Enthusiasm covers a lot of sins!

  I mostly judge people by skill level in the subject. If they are knowledgeable, I’m happy to pick their brain for info. It doesn’t matter if they are 20 years older or younger. Conversely, if they are new, I try and share the lessons and tricks I’ve picked up.

• ⁨Comment⁩ on ⁨I feel my life is empty. Is there any way to stop this?⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I’ve seen this more than a few times, as well as felt it myself. It’s a particular form of situational depression.

  In short, the solution is to “find your tribe”.

  Your problem is 2 fold.

  • Humans are a social animal. We need a group to socialise with, to be stable and happy. The requirements vary, but it’s almost always non-zero. The lack of meaningful contact sends us into a downward spiral.

  • 99% of people are boring to you. This is actually completely fine and reasonable. Unfortunately the 1% that aren’t boring to you tend to be hard to find. Even worse, weirder people tend to mask. They pretend to be normal and boring to fit in.

  The goal, therefore, is to find what 1% you need and where they congregate, with their masks down. They are out there, you just need to find them. You do this by trying new hobbies and activities. Most won’t hit the mark, but some will resonate with you. It’s OK to try a lot of things before you find it.

  For me, it was a makerspace. I actually ended up founding one, since there wasn’t one locally. I’ve seen a number of other people come along and discover there really is a group of weirdos that they fit into that aren’t boring. They, in turn, add their brand of weirdness to the group and make it better for all involved.

  Without knowing more about you, I can’t point you in the right direction. I can say they are out there. You just need to find them.

  Go find your tribe.
