  • Yes, even for them, the information they can get through a phone is lifesaving. They can learn how to build water supply and sanitation systems and shelter. They can learn how to farm and forage for food. They can find the best way to cross international borders and become a refugee. And so on, they can improve every aspect of their lives. Information is power, and with a smartphone they have access to the entire world, rather than just word of mouth knowledge in their local community.

    Obviously, places without any form of electricity are screwed, but satellite internet is rapidly becoming cheaper and more accessible so soon they won’t even need cell coverage.








  • Because it matters to the end user that all the instances are cross compatible, that’s the federated part. When I first heard of Lemmy and Mastadon as “self hosted social media”, I assumed that all the instances were isolated, and dismissed it as pointless. Once I learned what federation was, possibly through the email analogy, I was instantly onboard.

    We’re not at a stage where you can make full use of these platforms without having a basic understanding of how they work. A disinterested idiot is going to go " WTF is an instance, why is [whatever instance they landed on] so empty" and give up. The email analogy is useful for the interested skeptic and they’re the people that are most likely to stick around.

    In this thread the email analogy has been criticized for being not technically accurate enough and too technically accurate. That suggests it’s about right.


  • Maybe I’m optimistic here, but I feel like most users of email and Facebook understand that you can send email from Gmail to Outlook and that those are different services, but you can’t send a Facebook(message? story? idk I don’t use Facebook) to a Twitter user.

    I can’t think of a better way to explain that activitypub is an open and cross-compatible protocol. The only other big cross-compatible protocol is the web(HTML etc), but that’s hopeless, half of people don’t seem to understand what a browser is.

    Email is the only federated social platform that every normal person is familiar with. It doesn’t matter that the technical specifications are completely different. The metaphor goes as far as “in the fediverse anyone signed up with any instance can communicate with anyone on any other instance, like email”. For that purpose, it’s a good metaphor.







  • Why is a electric motor overheating dangerous? Surely any electric car is going to have a system to throttle itself if overheating is an issue, and it will need that with or without gears.

    The fastest accelerating electric cars are single speed, presumably because it’s not worth changing gear when you only have 2 seconds.

    I can see why it might be useful in specific product categories, but when it’s not helpful for price or performance or reliability, that’s going to continue to be niche. The real problem electric cars need to solve right now is cost and a gearbox isn’t helping with that.



  • Electric motors have so much torque even at low revs that a gearbox is unnecessary for most people. If you can get enough torque for a fast start in 5th, there’s no reason for the gearbox, you might as well save the extra complexity and keep the car permanently in 5th.

    Combustion cars have gearboxes because they only work well at a narrow range of revs. Bicycles have more gears than cars because humans have an even narrower range of revs where they work best at.
