  • Outbound Federation Bug
  • Hey! Seems my instance can receive posts from yours; both [email protected] and [email protected] seem to show the latest posts (newest one is from 19 hours ago). Can this federate back?

    edit: I made a whole comment on the issue page without realizing that 19 hours ago was also when you fixed federation... congrats on getting things to work! And maybe my coffee shouldn't be as strong...

  • Interact with this post if you see it
  • My instance is also having issues with federation. I actually found this from an issue on GitHub about it. I had to search up this post in order to see it. Hopefully my comment federates back!

    Test post

    I've made quite a few of these posts in different places already, but I seem to be experiencing a weird federation issue as of recently so I'm just seeing if it's a problem on the end of some servers or mine.

    i hope this works

    odd scaling issue with lmms
  • I remember managing to get this issue solved on my computer. Looks like a QT issue. I may not remember exactly how I fixed it, but try the solutions in this thread and see if it works: https://lmms.io/forum/viewtopic.php?t=34104

    In particular run export QT_AUTO_SCREEN_SCALE_FACTOR=0 and then run LMMS from the same terminal.

    Also in response to other comments, LMMS is actively being worked on (though updates have been slow) -- the last commit on the master branch was from 3 days ago, so that suggests that the project isn't abandoned but development's just rolling slowly.

  • Test post!

    I have the weirdest thing with my server -- outgoing federation doesn't work but incoming federation is fine. I've made a test post on a local community that doesn't federate, but I hope this will...

    edit: updated to 0.18.5 and seem to be getting the issue again, so I'm making an edit to see if this works

    edit: I tried editing this from Infinity to see if it sending an activity would work -- and it did! Maybe it's lemmy-ui?

    Nope, things literally started working again.

    Outgoing federation test!

    After I updated to 0.18.5 this seems to have stopped working.

    WARNING: Lemmy Self-Hosters, There Have Been CSAM Attacks taking place against [email protected]
  • Yeah... Just wow. I disabled pictrs and deleted all its images, which also means all my community images/uploaded images are gone, and it's more of a hassle to see other people's images, but in the end I think it's worth it.

    Through caching every image pictrs was also taking up a massive amount of space on my Pi, which I also use for Nextcloud. So that's another plus!

  • Pictrs has been disabled

    As pointed out by this post on c/selfhosted, CSAM has been appearing in c/lemmyshitpost. This has raised two serious issues with Lemmy, which is why I have disabled pictrs, the program for uploading image files and caching image files from federated posts that was designed for Lemmy.

    The first issue is that if someone posts something inappropriate to a Lemmy community (as opposed to, say, a subreddit), and a mod deletes the post, instead of it being removed from the server and removed from all other servers, it's simply removed from the server and flagged that it was removed from other servers. This creates confusion for users because they can still interact with posts that users on a home instance cannot, but if someone posts CSAM to a community, that CSAM will stay on other people's computers.

    The second issue is that Lemmy makes too much requests to other servers. Instead of the WebUI loading each image from wherever it was uploaded, so loading images to the user's computer on request of the user, it caches each image to the server. This results in a huge (and unnecessary) amount of storage space being used on the server, and means again that any NSFW or worse, NSFL images will be stored forever on the server along with important images, like post images created by users on the instance and the logo, and community logos. One could go further to say that Lemmy doesn't need to cache text, but I won't get into that now.

    All in all, both these issues, combined with how Lemmy is such a small community it doesn't have very active mods, leaves all server owners vulnerable to targeted attacks on certain communities. Such as what happened with c/lemmyshitpost, when people started uploading CSAM material. This material was federated with all instances, meaning single-user instances like us now have to do extra work to get these images off. Luckily for me though, I was able to remove all saved images and (for now) disable pictrs. If you disable pictrs on your server, you can still upload images via sites like postimages.com (which also has the added benefit of being able to upload gifs!).

    Thanks for your understanding everyone, and sorry for this wall of text!

    This should be a pinned post as it really captures the essence of my experience so far.
  • A bit of reverse image searching reveals this was the original XKCD comic (more specifically, the top middle panel): https://xkcd.com/1269/

  • Pick your Lemmy instance wisely...
  • Don't forget people on single user instances too! It feels pretty good watching drama and not having to worry about how this affects me.

  • reddit moment.
  • They don't! The first site I linked doesn't have a time limit, and for the second one, you can choose whether or not to give files one.

  • Scalies on the Fediverse?
  • I know, yeah! Talking a bit with you folks here really motivated me to actually start posting some content here, and honestly, on Lemmy in general! Apologies if this was a silly question because looking on it in retrospect yeah it's a bit weird to start making another community when there's so little content in Lemmy that there doesn't need to be that kind of distinction (and that kind of fragmentation might actually end up harming more than helping).

    But about my first point, who knows though... you might see some pictures of dergs turn up somewhere here. Maybe...!

  • reddit moment.
  • pict-rs, the software Lemmy uses to upload media by default, is a bit wack right now so people usually get around this (and some other issues) by uploading to sites like files.catbox.moe or postimages.org (the former of which can upload any media while the latter can only do images/gifs). I recommend checking that out - it can come in handy sometimes!

  • Scalies on the Fediverse?
  • I do have to admit I'm part of the problem...! I think that this probably is the reason why meme communities on Lemmy are so big right now -- memes are designed to be reposted, so we're seeing a lot of that content opposed to original content (which isn't a bad thing, but it tends to drown out other content on All pages). Maybe I can get around to making more art for once and I can start to populate Lemmy with more content :)

    But for right now, I agree that things are quite fine as they are. I don't really feel a need to create a separate community as I would on say, another larger platform, because right now this space (and others on the Fediverse) feels like a community where people's voices are actually heard. It's really refreshing, honestly. But yeah, it's nice to see what people think on this! Thanks for your input!

  • Scalies on the Fediverse?
  • That's true, yeah. I do really like how the Fediverse is growing (and quickly too!) so we might see that start to happen later on (I sometimes already see a bit of niche communities on Lemmy being created). But at the same time, I do have to agree that although there's less posts, there's a genuineness to each post that really makes me appreciate them more.

    Scalies on the Fediverse?

    Apologies if this isn't the best place to post this... but I've been wondering.

    When I was researching moving over to the Fediverse, I noticed I actually couldn't find that much scalie-specific instances. Which of course isn't really bad per se, as we still have instances like this which is totally awesome. But anyway, then when I moved to Lemmy, one of the communities I have been following on that other platform, r/Dragons, doesn't really have a Lemmy equivalent, which is a bit more of a bummer to me. Maybe there just isn't much of us on the Fediverse (yet)? I guess I want to ask this: anyone know of any scalies on the Fediverse? Or better yet, Lemmy communities? If there isn't any of the latter yet, I'd be totally willing to make one! Only thing is I don't have much to post there...

    Lemme know what you think (unintentional pun intended)!

    Some interesting statistics after I created lemmy.potatoe.ca

    I got this email from Cloudflare... apparently ~11 GB of data was sent in the past month alone! I was a bit worried, but then I realized that's from all the federation Potatoe Lemmy is doing with other servers.

    Also yeah, most requests are from Finland! I guess that means sopuli.xyz has the most Lemmy users?

    It'd be a interesting challenge for Lemmy devs to see how requests, and thus server bandwidth and operating costs, could be minimized in the future. This could lower the bar for new servers (such as mine) to enter the Fediverse.

    [Question] Security considerations when self-hosting Nextcloud
  • Yeah, Podman is definitely one of those things I would say to do the latter with. It's functionality is the same as Docker though (commands work almost 1:1, and even docker-compose works with Podman), it has better integration with other system components (like automatically creating systemd services to start containers when a computer is restarted), and it gets you away from Docker as a company while still being able to access their containers on Docker Hub.
    In the end though, I'd recommend sticking to what you're familiar with. It's always better to administer commands to your server that you know will work rather than learning as you go and hoping something doesn't break.

  • Here we go again
  • Firefox sorta does! If you only use tab groups (or profiles for that matter) to separate school tabs from work and personal tabs, I recommend giving the Multi-Account Containers extension a look.

  • Here we go again
  • Or worse, "Why should I switch to Firefox? Everybody's complaining about the performance of Firefox compared to Chrome, but Chrome just works for me."

    Blissfully unaware of the kind of power you're giving Google over the Internet by using their browser. I once had an experience where someone tried to use this to push me back to using Chrome.

  • [Question] Security considerations when self-hosting Nextcloud
  • I may not be able to answer some of the more security-oriented questions, but one of the things I recommend is using a proxy to "hide" your home IP address. IP addresses can contain a lot of information including location data, so it's a good idea to make things harder for attackers to figure out where you live. I'm pretty sure you can do this with a basic VPS setup, but I know for sure you can do this with Cloudflare (as I have it enabled on my server).

    As for getting reverse proxies set up from your Docker containers to the outside world using Apache, I can help. I use (rootless) Podman on my Raspberry Pi, meaning when I expose ports from my containers I have to choose port numbers greater than 8000. Once I have a port (let's say 8080), and a subdomain (I'll use subdomain.example.com), I just need to create a file in /etc/apache2/sites-available/ which I'll call site.example.com.conf. The content usually looks something like this:

    
      ProxyPreserveHost On
      ProxyRequests Off
      ServerName subdomain.example.com
      ServerAlias subdomain.example.com
      ProxyPass / http://localhost:8080/
      ProxyPassReverse / http://localhost:8080/
    
    

    Then you just need to enter the commands sudo a2ensite subdomain.example.com and sudo systemctl reload apache2 and you should be able to access your container as a subdomain. You should just need to forward port 80 (and 443 if you want to set up Let's Encrypt and HTTPS) on your router.

    Hope this helps!

  • Multimedia test!

    Looks like you can't upload any multimedia (gifs/videos) above 100 KB? In addition to the fact that you can't upload any images above a couple megs this just seems weird.

    Gif from Potatoman Seeks the Troof. No relation to this server.

    External image test!

    Uploading media to Potatoe Lemmy might not work, but can you link to pre-existing media elsewhere?? We shall see!

    0

    Image test!

    A BIT OF AN ISSUE WITH PICTRS: PNGs and JPEGs under 2 megs are the only files that can upload. Anything that's not an image file, or over 2 megabytes in size will give some JSON error. :(

    [Guide] Self-hosting a Lemmy server with Podman

    Hey everyone! I run a server with Podman instead of Docker (and on an arm64 processor), so when I wanted to host a Lemmy instance on it, I faced a bit of challenges. I ended up writing this guide so if anyone else is in the same pickle, this should make installing Lemmy closer to headache-free. If you're reading this post that means the guide works!

    First post!

    Well, after a bit of testing, everything seems to be working with Potatoe! There is an issue with sending emails though -- this is running on my home network, so my ISP blocks outgoing requests to port 25 (the port mail servers have for listening to incoming mail).

    There's also an issue with federation -- you might not be able to see the same number of posts/comments/votes as you would on servers where those posts/comments/votes originated, but this should be fixed in a later update for Lemmy (which is the reason why I'm on the latest branch).

    Things are still a little bit experimental, and this is running alongside a lot of other software on my 4 GB Pi, so I can only accept a few applications at the moment. If you're interested in anything Potatoe, please send me an email! I'm pondering getting better hardware, but I want to see how much it's needed first.

    Thanks for checking out my server and enjoy your stay!
