The MAX_TITLE_LENGTH is applied to posts that are fetched from other instances using activitypub. The posts that are posted within an instance do not pass through that processing step.

Yup, this was fixed in version 0.0.24! No worries.

What version do you have? I think you have one of the older versions, you can find the latest one here:

I think that the newest update changed something such that the the instances that updated to 17.0 are no longer being recognized by the crawler. So the crawler hasn’t been updated to deal with the changes.

Great job figuring that out!

At some point it would be fun to work on some new guides anyway :-)

I think that if you use the new docker-compile file, the one that includes the NGINX block, then you might not need to go through the step of the nginx configuration.

I have not tested this myself though, but I can test it when I make the updated tutorial.

I can do that, but I can’t right now, I am very busy writing for my thesis unfortunately :/

If I manage to write enough tonight I might be able to do it tomorrow.

Oh no! It is possible to save your SSL certificates by simply copying the files into your computer, then you don’t need to run the certbot again.

Try removing the lemmy.conf file from /etc/nginx/sites-enabled,

And then run:

sudo wget /etc/nginx/sites-enabled/uebishe.conf

sudo systemctl restart nginx

Or, I have made an nginx config file that will work for you

If you already created an nginx configuration file, move it somewhere else. Then, get the new configuration file to the nginx folder, and then restart the nginx service by running these two commands:

sudo wget /etc/nginx/sites-enabled/uebishe.conf

sudo systemctl restart nginx

Ah! So you skipped this step:

Now i skip old step about “wget -O lemmy.conf”

You need to have the lemm.conf file under /etc/nginx/sites-enabled, this is the file that tells nginx how to manage the connection. Don’t skip that step! Get that file and modify it by adding your domain name

Sorry, I did not realize that these files had not yet been updated with the changes necessary for version 0.17.0, which are described here:

I could not find an example of the files configured correctly in github, so I have uploaded some example files. You get them this way:


Then modify the variables inside {}, like the domain name and the database password.

Remove the following blocks from the docker-compose file:

  # communication to web and clients
  # communication between lemmy services
    driver: bridge
    internal: true
    image: nginx:1-alpine
      - lemmyinternal
      - lemmyexternalproxy
      # only ports facing any connection from outside
      - 80:80 
      - 443:443
      - ./nginx.conf:/etc/nginx/nginx.conf:ro
      # setup your certbot and letsencrypt config 
      - ./certbot:/var/www/certbot
      - ./letsencrypt:/etc/letsencrypt/live
    restart: always
      - pictrs
      - lemmy-ui

And try again. Does it work?

Do you want to install a fresh instance, or do you want to upgrade an instance?

If you are installing fresh, most of that tutorial is still going to work out. But you now need to pull the config file this way:

wget lemmy.hjson

If you install the more recent docker version, you don’t have to install docker-compose the same way. Follow the instructions from the website, and use ‘docker compose’ instead of ‘docker-compose’.

The nginx configuration does not need to change.

What problems are you getting?

No problem!

I thought it was a UI issue so I had created an issue there:

I can tag my messages as “mod” messages in communities that I don’t mod in other instances

An issue was opened for that three days ago:

I don’t think it is possible through the UI at the moment.

Gracias! (Posted from Jerboa)

Oh, that looks like an error in your lemmy.hjson settings file. If you share that one too with the passwords redacted I can check.

If you go to your lemmy directory and type docker-compose logs -f lemmy, what does it say?

Can you share your docker-compose.yml file, removing the database password and any other private information?

Also, did you change the variables in the Lemmy UI environment?

(Edit to specify, in the docker-compose.yml file the variables are now different)

The lemmy-ui environment variables have changed, and should now look like:

    - LEMMY_UI_HTTPS=true

There are also other instructions that you need to follow. Are you following the release note instructions?



docker compose logs -f lemmy

(or docker-compose) to see the logs.

Is the last message saying that the database migration is going to be run? If so, you need to wait. It can take a few hours.

Thank you for the great work that you are doing!

This update has a lot of very neat features that I’m excited to play with!

I just checked, and it is still possible to determine who has liked/disliked a specific comment or post in 0.17 by running a database query.

It is not something that I personally have a problem with - I suspect this might be a “necessary evil” to prevent double voting. And I would think that this is the default for any site with voting.

Hey, I had missed this post when I replied:

This site helps you search for communities in many instances at the same time:

Might be helpful too!

You mean that you want to stay within, connected to your user, and replace the content with the content from Then you would be able to explore instances more easily and find new communities to subscribe to.

There is no way to do that at the moment. only fetches some of the content from other instances - such as the content that’s users are subscrribed to, and the content that is manually requested by pasting the original Url into the searchbox.

I can’t think of an obvious way that this can be implemented without fetching a large amount of unsued content from the other instance, and that approach would become very resource inefficient as instances become larger.

Another approach could be to create instance relays or explorers that are modified instances that will focus their resources on discovery by fetching a lot of content that might live for a week or two in the instance, and then build tools into it such as filtering by instance. This instance would subscribe to every community of the instances in its list. You would still need to leave your instance’s site to explore instances, unless the relay is somehow connected to the original instance, but at least this would be an efficient way to explore.

As of now, what I do is that I manually explore instances by accessing their site in a new tab, and manually subscribe to new communities by copying and pasting the community Url into mine.

What is Calckey??

Maybe it would be helpful to make an introductory posts in the sublemmys or link to some videos about them!

Yes, that is how I did it :-)

It works for communities because their relative url is always /c/community@instance.tld

For posts and comments it won’t work because the post and comments IDs are different for each instance. For example, this post is at at mander and at at, so the relative urls are different.

Do you heat the pan first, then add oil? Or put the oil in and heat up with the pan?
I personally heat up the pan first, then put the oil in and after it's heated up add the ingredients. I go with the line of reasoning that doing it this way gives the oil less time to burn, thinking that if you do it the other way, by the time the pan and oil has heated up, the oil could already be starting to burn. I've never experimented, but I think this is more of an issue with electric stoves since you can modulate the heat more quickly with gas, ie turn it off if the oil's starting to smoke.

How can I chop onions without crying?
Onions are an excellent addition to many dishes, but cutting them can be frustrating when they make you "cry" all the time. Does anyone know any tips or tricks to help minimise the tears when chopping onions? [Asked by Caleb to cooking/stackexchange](

True! And with shrooms it is exciting to see how they change so dramatically in days.

It took me months to get my yagé (Banisteriopsis caapi) seeds to germinate, and it takes weeks to grow new leaves and drops the previous ones. I really hope I manage to keep it alive! So every leaf is a pretty welcome surprise.

My chacruna (Psychotria viridis) seeds won’t germinate after over half a year of trying 😓

I have created the community [/c/answered](/c/ If you run into an interesting question online for which a good answer was provided, this is the place to share it! The point of this community is to aggregate interesting questions that have been answered from all over the internet (like stackexchange, reddit, quora, etc). You can copy the questions into the post body and the best answer(s) into the comments. Other users may then address the answers directly by replying to the comments, or add their own answer to the question as a new independent comment. As of now, there is no constraint on the topics. Any answered question is fine! I have already made an example post, but I don't know how to create a relative hyperlink that would send you to the post in your instance. So just check it out in the community ;)

Why don’t metals bond when touched together?
It is my understanding that metals are a crystal lattice of ions, held together by delocalized electrons, which move freely through the lattice (and conduct electricity, heat, etc.). If two pieces of the same metal are touched together, why don't they bond? It seems to me the delocalized electrons would move from one metal to the other, and extend the bond, holding the two pieces together. If the electrons don't move freely from one piece to the other, why would this not happen when a current is applied (through the two pieces)? Asked by jcw in [physics.stackexchange](

Avogadro 2 still has a long way to go. Too bad the original stopped being supported. Thank you for your contribution!

Thoughts and prayers ✝

I agree. This can easily be exploited by a malicious mod. Since the original poster can still edit the title, it is better to just ask them.

Remember when Reddit’s CEO /u/spez decided to abuse his super-powers to edit user comments? That was not very well-received by the community.

Thank you for taking the time to explain your reasoning despite not owing us an explanation. I suppose one of the “cons” of a transparent modlog is that we only get to see the final output without getting the full picture, making it easy to get the wrong impression.

My recommendation would be to avoid the drama and hassle of inter-instance policing and simply undo that ban.



At home at the moment though, recovering from my second COVID infection 😅

The majority of new accounts created at would post ads about pills or crypto wallet scams shortly after being created. Now I have to manually accept registrations, and many do write that they want to make a post about their product. I deny those. But a few do get through.

I am not sure that they are bots, though, because they do fill in the registration form. And I might be wrong, but I think that a bot would need to be tuned specifically to interact with lemmy instances. I think that these might be actual people that manually crawl the web and spam.

Setting up instance again. Testing that federation still works [EDIT] Conclusions: - Re-creating an instance and creating a user with the same name as before creates an issue when it re-interacts with a different instance. This user's page won't load. - If a user changes its display name and/or icon after interacting with a second instance, the changes will not be reflected in the second instance. At least not within a few minutes.
