    Yeah, obviously you “can” merge, but in doing so you insert yourself into the middle of a 2 second gap creating 2 × less than 1 second gaps. Like I said, in this hypothetical everyone is a perfect driver that always follows the rules, so that’s not an option.

    For that matter, the driver behind should see that you are about to merge into a gap that’s too small and slow down to leave a space that’s at least 4 seconds big.

    I’d also like to point out that your attitude to driving is terrible, the size in meters of anything on a highway is irrelevant, 2 seconds is not a lot of time to react and slow down a car at 100, and that just because you “can” do something doesn’t mean you should.

    I have a question on this. Let’s assume everyone is a perfect driver and must have at least a 2 second following distance at all times. If there’s a free flowing queue of traffic on the highway with 2-4 second gaps between, merging in is impossible without someone slowing down and letting you in. Every time I merge this situation stresses me out.





  • I can speak as someone who thought they couldn’t do parties. Parties are incredibly intense, and can be the best or worst experience of your life depending on the smallest details. Eventually you will learn how to party best for you, what substances to take, what to wear, where to stand and what to do, which parties are just not going to work for you. Keep trying new things, but also if you’re not feeling it, take some time out or just leave.

    I think the older you get, the more you realize that everyone has imposter syndrome and anxiety all the time, but you just have to fake it until you make it. If you pretend everything is fine, it usually turns out fine.



  • By the way, 1 tablespoon of peanut butter does not weigh 14.79 grams. 1 US tablespoon is a unit of volume that’s equal to 14.79 milliliters(mils). Grams are a unit of mass. In order to convert between them we need the density. Because the metric system is great, the density of water is 1g/mil, so 1 US tablespoon of water weighs exactly 14.79 mils. However the density of peanut butter is a bit higher, so the US tablespoon of peanut butter will weigh a bit more.

    Additional pedantry, yes I did have to write US tablespoon every time. A US tablespoon is 14.79mils, a metric tablespoon is 15mils, a traditional Australian tablespoon was 20mils although now they mostly use metric tablespoons.







  • 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 tells me 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.
