Yay or nay, memes should be allowed in !python@programming.dev ?

Isn't c/Programmer Humor already for memes?

[–] ruffsl@programming.dev 6 points 1 year ago (5 children)

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?

[–] vahtos@programming.dev 4 points 1 year ago* (last edited 1 year ago)

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.

[–] LaggyKar@programming.dev 4 points 1 year ago

Agreed, let's keep memes separate from serious posts

@Ategon@programming.dev is working on tagging, but I wouldn't expect it anytime soon. It's a big feature.

[–] Jakob@programming.dev 2 points 1 year ago

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

[–] pythonoob@programming.dev 1 points 1 year ago

I didn't care before but you make a good point. I vote keep them separate.

I'm gonna need you to elaborate on this one

[–] dmad@programming.dev 5 points 1 year ago* (last edited 1 year ago) (1 children)

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.

I used Lemmy's cross-post functionality, but it doesn't seem to have marked it?! Original post is https://lemmy.ml/post/1213162

[–] Ategon@programming.dev 2 points 1 year ago (1 children)

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

[–] jnovinger@programming.dev 1 points 1 year ago

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.
