      Hear, hear!

      I’d prefer to keep all lang communities on topic. E.g. I occasionally block and unblock !c/programmer_humor when I want to read technical news or just have a laugh. If memes crossed into all local subs, then the noise-to-news ratio couldn’t be customized as easily.

      Although I suppose tagging posts would be a better compromise.
      Does Lemmy support tagging posts, or filtering feeds by tag yet?

        My thoughts exactly. Tagging them (if possible) is OK, but kind of annoying to need to go to all these different communities and filter memes when there is already a dedicated community for programming memes.

        It also may turn off new arrivals that may be looking for a more serious community, and think all/most of the content is memes.

        Tagging would make sense if the community becomes larger and naturally people start requesting it. For now, I think memes should stay in Pr. Humor

        xor has the property x ^ x = 0, and x ^ 0 = x. So, x ^ x ^ y = y

        a' = a ^ b
b' = b ^ a' = b ^ (a ^ b) = a
a'' = (a ^ b) ^ a = b

        This is pretty clever, I’ve never seen this for a swap.

          Couldn’t have explained it better myself. I don’t remember where exactly I first read about this trick, but it’s mainly useful in C or Assembly, as you don’t have to resort to using a third variable/register.

      It looks like it marked it on my end. Lemmy has two different cross post functionalities based on how you cross post, one where it shows the original post in the text and one where it shows up as a link under the new post

        Ah, I am seeing that now, thanks!

        I’m not sure if that was there originally and I just missed it or if Lemmy added it later when it got around to it.
