    This! I also configured my client to hide posts with ~10 keywords (trump, ice, kills, etc), and my feed suddenly had a much more diverse set of topics. Usually there is a common keyword between topics you’d want to see less of; you just need to keep it in mind while you’re browsing so you can find it!

    Unpopular opinion: I like the concept of daylight savings: 😅

    What’s written on a clock is entirely artificial, made by humans to use as needed in everyday life; It doesn’t matter what it shows, just that it shows the same for everyone

    I think we should decide what we want it to mean (e.g. sunrise always at 07:00, middle of the day at 12:00, move the sunset based on concrete statistics that prove it would minimize energy consumption, or anything else we want), and implement it in small increments

    In a world where 99% of clocks are digital (phones, smartwatches, computers), no one will care or notice if for 6 months every day they lose 42 seconds of sleep, and then for the next 6 months gain them back again; (computers that need a stable reference point usually use UTC anyway)

    Heck, even without modern technology: Germany was broadcasting the time on a specific radio frequency with DCF77 like ~50 years ago, for synchronizing train station clocks, so today it should be more trivial than ever to make this change in the clocks and software that people use 🤔

    I’m always baffled when I read news about unethical things that a piece of software does; I can’t comprehend how software engineers, people who probably have the ability to do critical and structured thinking, program such software and feel ok with it - they can’t just plead ignorance and say they’re just doing their assigned tasks or sth, they actively make the decision to participate in this.

    The managers, I think it makes more sense: they may be evil about coming up with these decisions, but may not have much exposure to the product to understand the consequences of how it works so they just get money and handle they contracts etc.

    But the people who write the logic, they’re the ones who are sitting down days at a time focusing on their task to think how to design the algorithms, from killing people, to simply tracking people online and exploit a user’s behavior, data about their personal life and relationships etc

    “Hmm yes if a user seems to spend much on microtransactions in games, we could maybe lure them to an online casino! Lets now work on the algorithm that recommends betting games based on their online behavior. Oh did they lose their job recently? They now have more free time to sink into our platform! We may be able to lure them with games that have small bets 🤔 I’m so good at my job I might get a raise now!”

    And I guess now with vibe coding this can only get worse 😕

    What is “too far away”?

    Hmm, you’re right, I guess I don’t mean the distance of the link by itself, but rather the fact that the number of hops and the dependence on central (?) high-power long-range nodes limits how far a message can go

    While technically a mesh network, I’m not sure that with 3-7 hops it provides the benefits of one; in theory, just by being mesh it should be able to have a much larger (unlimited?) reach, just like the Internet.

    Instead, from what I understand, user nodes are recommended to not participate in the routing, = they are just clients, but by being “mesh” they would be expected to actively participate in the network.

    In this sense of “peer-to-peer”, we could say that my ISP is also a peer, and if it lost the connection to all other ISPs it could still continue working within the reach of its infrastructure, = my ISP is off-grid as well, and my connection to the ISP is independent since they own the fiber

    Instead, I think the focus should be on building a distributed mesh network that is resilient and can’t be taken down by the failure of a couple of nodes. Similarly, with the dependence on LoRa radios: if e.g. the import or usage specifically of LoRa™®© chips is banned, the nodes who chose to use alternative technologies would not be affected and the network could continue to operate normally

    Hello, sorry for the random question, but I’m new and still trying to understand the benefits of joining the network and how it works

    What is the point of a network that:

    • Is off-the-grid but can’t connect nodes that are too far away
    • Is independent, but forces people to use LoRa which creates a dependence on LoRa-licensed radios
    • Is decentralized, but obviously needs few centralized higher power backbone nodes in order to function (e.g. in this case)
    • Is peer-to-peer, but from what I read it’s recommended to not have your node accessible at all times (or have it read-only?) in order to not have the TTL expire
    • Cannot connect remote networks together, but also can’t bridge them in some other way

    Is the main use case just connecting e.g. a couple of sensors on a remote farm a few kilometers away from your house, and have 2 neighbours relaying the messages to you along the way? 🤔 Why does that need a decentralized peer-to-peer network if it can just be done by simple repeaters?

    That’s not what my objection is about 😅 Of course low power consumption is important

    My point is about depending an independent peer-to-peer off-grid network on one specific technology

    E.g. imagine if TCP/IP, BGP, or HTTP were proprietary (instead of owned by standards organizations), and in order to connect to the Internet you would need to buy a network card that is licensed from the TCP/IP company! But since that’s not the case, people can connect to the Internet using any technology they want (Wi-Fi, Ethernet), but as long as their device uses TCP/IP, anyone can connect with anyone

    (PS maybe there is a better physical layer or routing example than the above 🤔 But I think the principle still stands)

    You don’t have to pay meshtastic any money

    They can still profit indirectly from providing services etc (which is fine)

    But even just the fact that in order to use the word “Meshtastic” ™®© I have to read https://meshtastic.org/docs/legal/licensing-and-trademark/ shows that it does not have “community” vibes but “Meshtastic™®© is ours and we’re just letting you use the source code etc for now” vibes

    Again, the fact that it is owned by someone means that the community (probably) does not have control over it, and one day we might need to fork the whole network and migrate every node

    there’s nothing they can do to stop you using it as you see fit

    If a specific radio is illegal, it’s easy to just find where it’s transmitting from and fine you; they already do this with pirate radio stations

    There is no way to be completely free of dependence on others

    But why be dependent on 2 companies instead of having the option to buy a radio from any company? Why is competition and diversity bad for an independent and off-grid network that we don’t want it to have a single point of failure? 🤔

    Not only it can make the network more resilient (which is supposed to be one of the goals), but it allows for experimentation and innovation in new technologies, which you can’t do if you’re locked into using LoRa™®©

    Why lock every user into a single technology just because some users want to have a long-lasting battery? (Which btw is probably important for very remote nodes and not the home and portable nodes that I think are more common).

    you’re going to want to buy some LoRa devices anyway

    Yes, but you’re not forced to; you can have nodes in your city that use any radio they want to communicate to each other, and e.g. your local hackerspace can have a node with multiple radios that bridges them to other nodes on the global network

    With Meshtastic™®©, if your country bans LoRa™®© radios you simply don’t have any other option, so the whole network is just done. With Reticulum or any other agnostic network they can’t ban all radio modules that can be used

    Reticulum is pretty much developed by a single person.

    Hmm that’s unfortunate, I didn’t know that 😕 But that’s a chicken-and-egg and network effect problem; we shouldn’t be “forced” (network effect) to use something that is not ideal just because more people use/develop it, otherwise we will never have a better alternative, because no one wants to develop it because no one is using it because no one wants to develop it

    At least for me, dedicating energy to build a Meshtastic™®© node would feel like I’m making something that profits LoRa™®© and Meshtastic LLC without trusting the “independence” of its every aspect. It transfers the dependence from the ISP that brings the wire to the home, to the companies that make Meshtastic™®© and LoRa™®©, but it’s still a dependence on one or two external companies instead of an independent community like I’ve seen with other local WMNs over the years

    (I don’t have the experience to say that Reticulum is the best option, but it’s the main agnostic network I’ve seen with the little search I’ve done; people reading this feel free to make suggestions! 💚)
