No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Just in case anyone is using their account here to post to off-instance communities: those posts and comments seem to have a very high failure rate. There is a lot of activity and accounts on this instance. This is to raise awareness, not to pull people away or break up the lemmyverse. Quite the opposite really: there is a technical problem on this instance that might be preventing the lemmyverse from functioning as it should.

Lemmy.world and some others have held back on the 0.18.0 back end update because the admin did not want to forego this Captcha integration, which broke in 0.18.0. Version 0.18.1 is expected to release soon, and address the regression with Captcha.

The new version also reduces its reliance on websockete, which should address a number of other quality-of-life problems on this instance, such as the random post bug (and hopefully the 404s/JSON errors I've been getting all afternoon).

Hopefully just a few more days and we'll be back to rights.

From my understaind it's not a reduction, but a complete replacement.

[–] [email protected] 15 points 1 year ago (1 children)

You're probably right. I'm not a programmer and am not familiar with the code base so I was avoiding speaking in absolutes.

I don't think it's a version issue. It could be, but testing I've done says otherwise. There's plenty of 0.17.4 instances that, despite other bugs, have no problem sending and receiving updates from other instances. I hope you're right. I don't run the instance so testing reveals mostly speculation.

It's a known issue:

https://github.com/LemmyNet/lemmy/issues/3101

https://lemmy.ml/post/1453121

Seems to be growing pains from Lemmy having to scale up in a very short amount of time so hopefully they are able to find a workaround soon.

It's not happening everywhere and all the time but it happens enough for you to think a post or comment has no engagement when it does just not on your instance.

So I’ve been thinking of spinning up a personal instance. I have the tech chops for most projects like this in a small scale but are there any reasons why I shouldn’t use Lemmy in that way?

[–] [email protected] 9 points 1 year ago (1 children)

Do it. Be super aware of how federation works though. The more stuff your users subscribe to the more network traffic you will need to accommodate.

[–] [email protected] 5 points 1 year ago (2 children)

Is there any use to spinning up an instance, only allowing say 10 people max, then just keep it updated and let it run, to take the load of those ten people off the bigger instances? Is that too small time to be useful? I have pretty weak upload.

[–] [email protected] 3 points 1 year ago (1 children)

Upload will depend on your user's activity (posting/voting/commenting.) Download will depend on that PLUS what the users are subscribed to.

[–] [email protected] 1 points 1 year ago (1 children)

Just trying to get a sense if it's worth bothering with my 10Mbit up.

[–] [email protected] 2 points 1 year ago (1 children)

It's really quick to get running. You need a fairly reliable IP/hostname as this is how your server will talk to all other servers and users. If you use dynamic dns, make sure it's rapidly updated if your ip changes.

[–] [email protected] 2 points 1 year ago (1 children)

Yeah, I just don't want to set it up, realize it's trashing my home connection, and then have to boot off those ten users. Maybe I'll set one up with just me, then if everything is alright, add one more and see. Thanks for the tips! :)

[–] [email protected] 2 points 1 year ago (1 children)

That's what I am doing to suss it out. I'm a data nerd so I'm looking carefully at how to contribute and watching what's going on sub-meta..

I think that would be worth it, yeah. Of course if you are hosting it on your home network there will be some added security concerns (and that might make it better to only allow signups to friends/friends of friends/etc). The way I see it is that some instances are going to host the largest communities, and therefore those instances are going to need to handle all of the incoming/outgoing updates to posts in those communities. Right now they can't do that reliably and push updates out to all of their users' devices.

So in the long run I think having small/medium instances (say a couple hundred, not tens of thousands of users) will be the way to grow. These smaller communities can push updates to their smaller user count reliably, and then have more resources to handle federated content coming in and going out.

[–] [email protected] 8 points 1 year ago (1 children)

What do you think is causing the failures? How are you seeing the fact that it's failing?

[–] [email protected] 6 points 1 year ago (1 children)

Like you mentioned afterward. Comments and posts just plain failing to land on any other instance. Also I run an instance for testing and can see incoming connections. lemmy.world fails at a protocol level, not at the application level. It's a, IMHO, bandwidth issue. Hopefully the admin is aware and wants to fix it. I'd say he has a responsibility, but he doesn't. lol.

[–] [email protected] 1 points 1 year ago

That's not good

[–] [email protected] 7 points 1 year ago* (last edited 1 year ago) (1 children)

This is the problem we are having with fast growth on a few select communities. The largest servers are being bogged down simply because the software has not been tuned for these large types of instances yet. ActivityPub works best (in it's current state) by spreading users over smaller/medium sized instances. Folks need to take a look at other instances (and I agree it is hard to find them for a newcomer). You can look at https://fedidb.org/ to look at instances that have been indexed running kbin, lemmy, and other software.

Joining a smaller instance means that your server is not being bogged down by tens of thousands of other users trying to pull updates to their devices at the same time. You can still see the content from other instances, and in many cases it is more reliable because your smaller instance actually has the resources to handle pulling in the posts you want to see. The server-to-server communications that make content federation possible are less resource intensive than pushing updates to user devices. Less users on an instance = more server resources to actually federate content. In the future I am sure instances like lemmy.world will be able to handle the user traffic and federation traffic smoothly, but for now the best way to ensure stability is to join a smaller instance.

(Plug for my instance: https://remy.city, a general purpose Kbin instance. I set it up for personal use but anyone is free to join me in using it. I have defederated from the instances with more extreme viewpoints userbase-wide (like lemmygrad and exploding-heads), and from lemmynsfw.com because of content hosting concerns. I'm open to suggestions on others.)

[–] [email protected] 1 points 1 year ago (1 children)

First, thanks for putting your instance out there! We need more open servers.

Second, lemmygrad is straight-up Marxist, which is about as far left as you can get - pretty much the opposite of "alt-right".

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

You are totally right and my brain definitely farted on that one. Extreme is extreme to me I guess. I'll edit to reflect that.

[–] [email protected] 5 points 1 year ago

I saw this on lemmy.world, went to reply to a comment, realized I wasn't on my instance, flipped back and I can't find it, so sadly I fear you might be correct that there is something wrong.

[–] [email protected] 4 points 1 year ago (3 children)

I find everything to show up pretty well. Have an example?

[–] [email protected] 5 points 1 year ago

Yeah, take a look at my profile from the perspective of lemmy.world:

https://lemmy.world/u/liara

Then compare with the comment count compared to other instances:

https://lemmy.ca/u/[email protected]

https://lemm.ee/u/[email protected]

9 of my comments haven't federated and are visible only to lemmy.world

https://lemmy.ml/u/[email protected]

22 comments made it to .ml but that's still missing 6 comments

[–] [email protected] 4 points 1 year ago

A post I sent 4 hours ago to lemmy.ml wasn't showing up. After I edited it once with no changes, it showed up as posted 1 minute ago. It's definitely an issue taking place. You can check to see if your posts are showing up at their destinations with the rainbow federation link button next to posts.

[–] [email protected] 2 points 1 year ago (6 children)

This post can be an example. Check: https://sh.itjust.works/post/446063 Do you see our conversation?

Also keep in mind that defederating (blocked instances) will prevent posts and comments from syncing between instances as well.

You can see blocked instances on lemmy.world here: https://lemmy.world/instances

[–] [email protected] 2 points 1 year ago

Correct. I am not testing with any of those instances. You shouldn't expect that to work at all, but I guess some users might not know.

[–] [email protected] 2 points 1 year ago (1 children)

I’m on kbin.social and I can see this ;)

[–] [email protected] 12 points 1 year ago* (last edited 1 year ago) (2 children)

Hilarious. This comment doesn't show on sh.itjust.works, which makes total sense. lemmy.world is responsible for sending it to other federated servers. Maybe kbin > lemmy right now?

[–] [email protected] 1 points 1 year ago (1 children)

OP, This highlights something else - I think the reason you are getting down votes is that most people seeing this thread are not on lemmy.world. The heading is a bit misleading (or potentially wrong) from the perspective of a federated user - which is most of us!

[–] [email protected] 5 points 1 year ago

OMG. You're right! I just edited the title. Which, lol, will not show up everywhere.

[–] [email protected] 2 points 1 year ago

This isn't a question

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago) (3 children)

(ignore me) test post from sh.itjust.works account
