Audiophiles, I need your advice. Looking for a mobile option for a bluetooth connected speaker that can play in the 20-100 hz range.
  • Double check that the problem isn't your hearing aid driver but rather your hearing aid codec support.

    Bluetooth audio devices need to agree on an audio compression format before they can send audio, and the default lowest common denominator codec that all audio devices support is extremely bad at low frequencies (and is all around terrible). It could be that your hearing aid is good enough but doesn't support whatever high-fidelity codec your coworker's stethoscope supported. Investigate what codecs your hearing aid supports and what the steth supports. You'll probably want something like LDAC, LC3 (aka LE audio), aptx HD, aptx adaptive, or preferably even aptx lossless.

    If you're considering investing a lot of money anyways, you may want to consider replacing your hearing aids with ones that support this functionality (the frequency response and the codecs).

    As someone else already pointed out, if your current hearing aids don't support below 100hz, then even if you play the sound over a speaker, your existing hearing aids are just going to act as earplugs. You may need to invest in different hearing aids or just live with taking out your hearing aids for the foreseeable future. Or I suppose just blasting the heartbeat over the speaker to bypass your hearing aid (caution wrt audio feedback lol)

  • Custom remote backup
  • What are you using for your main backup? It probably has a feature for doing remote backup / duplication. You're best off using that.

    If you don't, then I think that's probably your first order of business. There are a bunch of good COTS NAS devices that support remote backup to a similar device or to the cloud. Synology generally seems to be the easiest to use based on reviews, but recently they've been getting picky about hard drive support.

    If you'd rather DIY then there are some FOSS software options to let you build your own NAS and then back it up to the cloud or to a remote device running the same software. These can get pretty complicated from what I can tell (I'm in the process of doing something similar, been researching). Options include OpenMediaVault, and TrueNAS. TrueNAS seems to be "better" but more complicated and easy to fuck up.

    Unraid is also very popular, but it costs money to get a software license. Users swear by it, though.
    And on the outside HexOS - a fork (or maybe alternative front end?) of TrueNAS, by some former Unraid devs, with the goal of making TrueNAS as easy to use as Unraid. But it's both paid and beta, so probably not a good choice yet.

    These will all allow remote backup to cloud or to a remote device running the same software. They also typically support some kind of virtualization with an app store, so you can use your NAS to host other servers like a media server or immich or home assistant, etc (although app ecosystem abundance will vary).

    Wrt hardware, you'll have to look up system requirements for the software you want to use. For example, TrueNAS uses ZFS filesystem, which wants a lot of ram if you need it to perform well.
    If your r-pi can run the software you want, then you can get a SATA hat for your pi, to run a couple hard drives. You can also get NAS cases for your pi.
    I probably wouldn't recommend leaving a mess of cables and parts at your friend's house across the country, it's better for both of you if the system is fairly well contained - enough for them to move it without risk of parts getting disconnected.

  • Considering that AI is "hallucinating", and able to make up information that seems true based on what the model was trained on, what is the difference between current AI and the human brain?
  • That depends on how hardcore of a fatalist you are.

    If you're purely a fatalist, then free will is an illusion, laws and punishment are immoral, consciousness is meaningless, and we nothing more than deterministic pattern matching machines, making us only different from LLMs in the details of our implementation and from the terrible optimization that evolution is known for.

    But if you believe in some degree of free will, or you think there is value in consciousness, then we differ because LLMs are just auto-complete. They psudo-randomly choose from a weighted list of statistically likely words (actually token) that would come next given the context (which is the conversation history and prompt). There is no free will, no understanding any more than the man in the Chinese room understands Mandarin.
    The whole conversation is so full of charged words because the LLM providers have intentionally anthropomorphized LLMs in their marketing, by using words like "reasoning". The APIs from before LLMs blew up provide a far less emotionally charged description of what LLMs do, with terms like "completions".

  • What is this shit? I have to be signed in to watch any video now?
  • only we are allowed to steal these peoples content

    I guess beware the danger of ToS that grants the platform unilateral rights to use your content they host; just because you don't care what they can do with it now doesn't mean some new tech won't come along that lets them use your content in ways that horrify you

  • Very large amounts of gaming gpus vs AI gpus
  • Thanks!
    That helps when I eventually get around to standing up my own AI server.

    Right now I can't really justify the cost for my low volume of use, when I can get CloudFlare free tier access to mid-sized models. But it's something want to bring into my homelab instead for better control and privacy.

  • How to use a domain I own to self-host services?
  • It depends on your motivations and security requirements.

    If you're already hosting Home Assistant, there is an add-on for CloudFlared which will take care of most of everything for you, using CloudFlare secure tunnels.
    It even does simple subdomain reverse proxy, to serve your other services.

    It requires that you use CloudFlare for your DNS entries, and it won't secure your host for you (they do offer some free services to help a little), and you still end up depending on a cloud service provider so it's not pure self hosting.
    But it's free, you're still mostly in control, and it's less likely to catastrophically mess up your netsec if you're a beginner.

  • Contemporary cyberpunk recommendations?
  • I wouldn't call DCC cyberpunk.
    But it is an entertaining read, and probably the best of what LitRPG has to offer, besides maybe He Fights With Monsters. If you like the genre will depend entirely on how cringy or not you find rpg mechanics in your stories.

  • The movie cars is crazy

    Imagine living in a universe where, without even trying, you can run so fast that if you trip, you will die and splatter your body over a couple hundred meters of ground. And if you trip into someone, it'll kill them and possibly an entire pile of people.

    Like, in motor racing, the cars get wrecked but the drivers are fine. In the movie Cars, they all die. The race spectators are watching a blood sport.

    How do people like toast and bread rolls, but not bread crust?

    What is a bread roll if not all crust?\ What is toasting, if not making the whole piece of bread more crust-like?

    Low flow toilets

    When toilets try to save money by reducing the amount of water they use per flush, but you end up having to flush like 3 times 🤬

    Sitting on the toilet

    Be me. \ I've started sitting down to pee because it's cleaner. \ Stand up after I've finished peeing. \ Pull up pants. \ Turn around to flush. \ There is poop in the toilet. \ I forgot that this time I had sat down to poop.

    How accurately is poison depicted in fiction from the middle ages and renaissance?

    In old plays and stories, such as Romeo and Juliet, poisons are depicted as being fairly fast acting.

    Would they really have had access to such poison, or was it simply creative license? What would a realistic depiction of a poison of that era be?

    What counts as an attack for the purposes of the invisibility spell?

    I'm trying to figure out a ruling for something one of my players wants to do. They're invisible, but they took a couple of seemingly non-attack actions that my gut says should break inviz.

    Specifically, they dumped out a flask of oil, and then used a tinderbox to light it on fire. Using a tinderbox isn't an attack, nor is emptying a flask, although they are actions , and the result of lighting something on fire both seems like an attack and something that would dispell inviz.

    I know that as DM I can rule it however I want, but I'm fairly inexperienced and I don't wanna go nerfing one of my players tools just because it feels yucky to me personally without understanding the implications.

    Is this an attack or is there another justification for breaking inviz that is there some RAW clause I didn't see? Or should this be allowed?

    I miss when you could get a flagship phone that could fit in your hand

    I know I have small hands but c'mon. Flagship phones these days are strait up small tablets, not even what we'd have called on phablets 15 years ago.

    I know it's what people buy, but I'm still sad that if I want a phone that small then I have to deal with camera and display a couple gens old

    If there is one thing I know about the Stafford Gambit, it's that it's SO EVIL

    I can't stop listening to this.\ I feel like I need to go play chess now. Idk if it's AI generated or not, but it's so catchy

    What is your favorite extinction event, and why?

    I'm probably going to judge you if you say Holocene, without an interesting non-trivial reason.

    The OG super graphic ultra modern girl

    I remember everyone calling her androgynous at the time. Looking back, that was an absolutely wild thing for people to think.
