  • I want to remind everyone that Lemmy has had a bot crisis, a while ago I did some research into botted instances and I estimated something like 40% of user accounts are bots. Although this was a while ago so I’m not sure if that is remotely accurate anymore

    Many instances will have taken steps to start purging user accounts, at the scale of Lemmy, that downturn could be entirely explained by these bots being removed

    Obviously some users will leave but i do feel it’s worth noting this fact




  • Right well that makes sense. And is also a very good point. I don’t really see why you couldn’t do that. So I guess it is arbitrary. Although you then have the question of which case occurs more commonly, which is imo actually quite interesting, but also entirely pointless, since good luck showing one case to be more than the other. It’s like that door and wheel question.


  • I don’t see it mate. So you’re going to have to tell me, sorry.

    The point I’m trying to make is that using Pemdas/Bedmas is the most effiecent way of removing brackets - I actually don’t 100% know that but I doubt it creates hundreds of brackets - if thats slightly clearer.

    Yeah I haven no idea what I was saying when I said that, I’ve edited my comment a bit.

    On that note though using your example I think I can illistarte the point I was trying to make earlier.

    1 + (2*3) by always doing multiplication first we can remove those brackets.

    (1 + 2) * 3 can be rewritten as (1 * 3 )+ (2 * 3) so using the first rule again makes a sense. That is a crappy explaination but I think you get my gist.

    Pemdas isn’t as arbitrary as people in this thread think it is.

    I love maths, and I’m going to butcher any attempt to explain why pemdas isnt totally random. But you can look it up if you wanna know more I guess

    Besides no one ever uses that notation - by the time you learn about quadratics, you leave multiplication symbols out of the equation entirely and much of the notation changes shape, with division exclusively being expressed as negative powers or fractions.

    At that point you aren’t going to make mistakes, since each hyperlevel uses a different style of notation. Pemdas is used to teach 4 year olds, and it’s fucking dumb. What happens with a log, or sine function. Don’t even get me started on integrals and derivatives.

    Pemdas is shit, but not because it’s abirtary. In fact it’s shit because it’s a shithole acyromn



  • If they had recognised what they had done to piss people off, this post would’ve done quite alot. If they had said that they fucked up when making the API changes and wanted mods to come help rebuild the API, that alone would’ve done an impressive amount to lower peoples nerves. They wouldn’t have even needed to have acted on the advise. Instead they take zero blame, which imo only pisses more people off.

    Metric is based in such a way that the idea is ease of unit conversion.

    In base 4 multiplying by 4 would change the unit to kilo or whatever. That would be metric but base 4.

    We use base 10, you can argue about the validity of using base 10 but it bears no effect on the metric system. And yes arguements about bases exist.

    Base 12 Base 6 Base 60 are all common suggestions. But base 10 is what we are probably are going to be stuck with for a very long time.
