  • If you’ve never tried it, Google Earth VR is tons of fun! I don’t know what it is about looking at little miniature cities, but it’s just so compelling. Also fun is when you turn on human-scale and actually have to look up at the buildings and such as you walk or fly through the city, or the Grand Canyon, or whatever!





  • I wouldn’t think it’s related because the very short, 50ms pulse of pink noise has to be precisely timed with the peaks of your existing brain waves to give those waves an extra push. Similiar sounds in nature would occur at random times and antagonise your brain waves just as often as it helped. Imagine trying to push a kid on a swing at random times. They would end up kinda vibrating and not really swinging at all.

    On the other hand, perhaps the random times it helps is very beneficial, and the random times it hinders are more neutral, yielding a net benefit.

    Still, it would seem very odd that your brain is perfectly capable of producing the waves it needs, but somehow evolved to need the sound of crickets to help it along.


  • To deliver these bursts at the peak of the brain’s slow waves, the researchers had to measure each participant’s EEG activity as they slept. This proved challenging because they also needed to measure fMRI signals to monitor CSF flow, and the magnetic fields used for fMRI interfere with EEG signals.

    To overcome that, the researchers developed a way to process the EEG signals to eliminate the noise caused by fMRI, very rapidly — in less than 100 milliseconds. To make up for that small lag time in the EEG measurement, they also developed an algorithm that could predict when the slow wave peaks would occur. This allowed them to deliver the pink noise stimulus at the correct time.

    That seems like a lot of work to try such an odd idea. What inspired them to try this in the first place?


  • The problem of free will goes much deeper than that, and none of what you said really applies. Your brain exists in the universe, and follows the laws of the universe, and physics are either deterministic or they’re random. Interactions at the macro scale often follow deterministic behaviors. (Think billiard balls and such.) But then when you get down to the quantum scale, the results are truly random. Hell, the three-body problem is another situation that’s truly random.

    So where is the room for free will? It’s obvious that your behaviors are based on things happening in your brain, and the things happening in your brain are just chemical reactions. Chemical reactions either do prescribed things or random things. How can your mind influence them?

    Here’s another philosophical angle. I first heard the idea from a classic philosorapter meme. “If we act based on our values, but don’t choose our values, do we really have free will?”

    (I had to recreate the meme. I couldn’t find it.)

    If you think about it, you never really choose your values. You feel them in your chest. They can change over time based on your lived experience, but no one sits down and says, “I’m going to choose be a social democrat”. You might slowly come to the realization that it’s the correct way to be, but you can’t choose that any more than you can choose to be heterosexual or choose to enjoy eating smoked salmon. You have to feel it first. You don’t choose your feelings. They’re reactions to stimulus. Even fighting your impulses in order to do something else is itself driven by feelings.

    The beauty of the brain is the strange loops and feedback mechanisms that allow you to analyze information. And some day, all of a sudden you realize your values were wrong and you change and grow, but there was no point where it was a choice.

    Every action you take is dictated by impulses that you can’t control. The impulse to eat, to fuck, to get out of the rain, or whatever. None of it is truly a choice. If you think it is, you can wind back the train of thought every time to find that it comes down to inherent values and impulses. Neither of which you choose.

    Here’s an example. Someone’s having a really bad time and they’re homeless maybe and addicted to drugs, and then someone comes along and says, “Just quit the drugs, and get a job and stop being homeless. I did it. So can you!” All that means is that that person at one point found the gumption to go through withdrawal and get their life back on track. But the thing is, they didn’t choose to have the gumption. They just… had it. Or they had help. Either way, there was no choice involved.

    For me, this conclusion that we don’t have free will doesn’t impact my personal life very much. It doesn’t mean I can suddenly do whatever I want and blame my lack of free will. I do exactly what I was going to do anyway, based on my values and impulses. But it does help me forgive people who seem like they’re total assholes. You know, criminals and such. When you can accept that people act based on impulses which they really can’t control, then you can be more forgiving, and learn to love people as the flawed humans they are. I’m not saying it’s easy. I’m not Christian, but that’s the kind of love and acceptance that Jesus taught, and I believe it only comes if you abandon the idea of free will.

    And the best way to help someone be better is talk to them, which affects how they think and gives them new perspectives. The only way anyone can change is to receive new input that changes their behavioral loops.

    This is why I don’t think any kind of criminal justice system should impose punitive sentences. If you need to sequester someone from society to protect others, then fine, but that sequestration shouldn’t specifically be punishment, and I can’t stand it when people make rape jokes about prison.

    And why even bother being a better person if no one has free will and nothing really matters? Well, people have minds and feel pain, and I happen to value not causing people pain.

    Then again, I’m also (internally) an asshole when people drive aggressively around me. I can’t count how many times I’ve yelled out loud, “I hope you die in a fire!” when someone does a particularly dangerous maneuver and puts everyone else on the road at risk. That’s not very forgiving of me. But I’m a flawed human just like everyone else, acting based on my impulses. ☹️




  • I have the same phone and I’m in the same situation. I’ve never installed Gemini, and I don’t use any AI features, and the new voice is fucking horrible. It sounds like a disaffected Gen Z’er with way too much vocal fry and uptalk.

    I switched to the other US English voice, which sounds like the old Google Maps voice, but, like you said, doesn’t give any detailed directions.



  • This is no longer accurate. Here are the important details.

    Google:

    We are introducing an advanced flow through which advanced users will be able to install an app from an unverified developer after acknowledging the potential risks and completing a one-time setup.

    Android is introducing an advanced flow for power users who want to take educated risks to install apps from unverified developers. It’s a one-time setup for users to install apps from unverified developers after acknowledging the risks. It’s designed to protect user choice while adding in safeguards to protect users from being tricked or coerced into disabling security protections. Preview it in our video or blog post.

    You can continue to use any alternative app store. For apps distributed from verified developers, users won’t see a change in their download experience at all. For apps distributed from unverified developers, users can enable advanced flow with a one-time setup. Last updated: June 8, 2026

    I urge you to edit your post to clarify what’s really happening. I’ve been feeling sour about the whole situation for weeks, and was so relieved that there’s a solution besides wiping my phone.

    I might install GrapheneOS anyway, at some point, but I no longer feel I must do so to keep using the 20 or so F-Droid apps I use. I was really not looking forward to wiping my only phone.

    As soon as I can buy a solid Linux phone, I’m ditching Android and Google forever, but for now, I’m glad I can just keep doing what I’m doing. You just have to jump through a few hoops to enable installing and updating software from “unverified” developers, but whatever… It sucks to have to do it and wait 24 hours to complete the setup, but once you do, you can install any apps you want.

    Downvoted for sharing the truth. Good job, Lemmy. 😑



  • The way the runes warp on the pages look more realistic, but can make them harder to parse at a glance, which can definitely be troublesome.

    That’s funny, because I personally make no attempt to memorize the glyphs in a run. I just inspect every scroll in the shop, and it tells you the name before you buy it. If I see one scroll I like, I can memorize the glyph for one second to count how many are being sold.

    Glyphs on unidentified scrolls don’t really matter, and ID’ed ones in inventory have icons. If I see a scroll on the ground, I pick it up. The only time I inspect scrolls on the ground is if I want to use a Wand of Fireblast. If it’s Upgrade, I blast away. And if I think a scroll might be Transmute (from one of those choose-three rooms) I use the note system to label it.

    So when exactly are the glyphs troublesome? They could be blank icons, and it would barely affect my gameplay. 😄

    …maybe just an option to add a symbol to potions similarly to scrolls?

    ID’d potions already have symbols, although Toxic Gas and Paralysis can be confused since they only vary by color.

    Elixers don’t have symbols, though.
