I just got burnt. Wrote up a relatively high-effort post in:

http://mandermybrewn3sll4kptj2ubeyuiujz6felbaanzj3ympcrlykfs2id.onion/c/water

clicked sumbit, and it simply ate my msg. Redrew a blank form.. no way to recover the info loss. This is my 1st use of the onion, so I did not think to enable 1st party j/s (which is strangely off be default in noScript on Tor Browser despite clearnet sites having 1st party js enabled by default). It’s unclear if it’s a JS problem or if it’s because the onion version uses a quite old/classic reddit-like theme. In any case, it sucks.. it’s a defect for sure.

I'm experiencing a weird bug lately.

When I'm logged in, if I follow an external link (from lemmyverse.net, for instance) to here, the tab that opens is not logged in, and stays that way even if I navigate around the instance. If I then open another new tab, and directly visit mander.xyz, I'm logged in correctly as normal.

I'm wondering if anyone else is experiencing this? I don't know what could cause this or how to find out if it's a bug with lemmy, mander, or my browser config.

It happens consistently with any mander.xyz community. Errors nearly identical to this:

{"error":"unknown","message":"Request error: error sending request for url (http://pictrs:8080/image/original/4083b4bb-ab1d-45cc-9ff0-72280ce5c2ff.jpeg): operation timed out"}

This time it was this image:

https://mander.xyz/pictrs/image/4083b4bb-ab1d-45cc-9ff0-72280ce5c2ff.jpeg

It only happens with images. I only browse on mobile, android. I've had it happen in Firefox and the boost app, haven't tried it anywhere else. Let me know if I can provide any other info that will help.

This only happens to me with mander.xyz, and consistently happens every evening with nearly all images. Maybe 1 out of 20 times I'll get lucky and an image will load. There are too many communities I like here so I haven't just blocked it yet, hoping it can be fixed eventually. :)

Edit: I did see that other post about broken images but it looked like the error was different from the one I always get so I made a separate post.

Anyone else noticing? It seems to be affecting other instances as well, since instances hot link to eachother.

The rate limiting seems to get much worse in the evenings.

lemmy.world:

mander.xyz:

{
  "code": "object-request-error",
  "msg": "Invalid status 429 Too Many Requests for Some(\\"01/90/24/ad/1d/8d/7e/8a/82/ee/7104ff150707.png\\") - {\n \\"message\\":\\"Too many requests\\"\n}"
}

I'm working on re-creating a logo we had last year onto this year's #Canvas. The site, complete with template, is linked above!

#Canvas2024

After all these recent upgrades, updates and improvements, things are going veeert smoothly and fast!🔥 I think this comment I made about a week ago about experiencing slow responses is no longer valid!

Sal and anyone else who helped, you did a great job! Thank you!☺️

The instance has been updated to version 0.19.4!

You can see the official release post and notes here: https://lemmy.ml/post/16585359?scrollToComments=true

Since this update required some manual intervention anyway to update the database version, I took the opportunity to perform some overdue server maintenance and upgrades.

I have migrated the server to a more powerful configuration, and changed the way image files are being stored and served (object storage as opposed to filesystem storage).

I am also aware of some federation issues that have affected this and other instances. I am not sure whether this upgrade will deal with these problems automatically. I will be looking into it and hopefully will implement some solution soon.

Sorry for the downtime experienced in the past few days, but hopefully with the more powerful server the experience will be smoother and will remain so for a while.

For other admins and users interested, this is a bit of information about the server

The previous configuration:

Hosting provider: serverspace.io

8 GB RAM

4 Core CPU

50 Mbps network

400 GB SSD

Cost: $55 / month

The 400 GB SSD was being used to store both the server's database and the image files, and this component in isolation had a monthly cost of $36. I have migrated the images to an object storage provider ($6/month for 500 GB), and used the resources previously used for disk space to increase the other parameters. The new configuration is a lot better and less expensive.

New configuration:

Hosting provider: serverspace.io

Object storage provider: contabo.com

16 GB RAM

6 core CPU

50 Mbps network

100 GB SSD

500 GB Object storage

Cost: $47/month

Thanks a lot to the lemmy and pict-rs devs for the hard work they put into developing the infrastructure!

Hello everyone!

About 2 weeks ago, kbin.social went down due to maintenance issues, but it seems like federation hasn't been restored on this instance.

Specifically, I am subscribed to https://kbin.social/m/greece which federates with lemmy.world, but on this instance posts since 2 weeks ago and later dont seem to be federating.

Could you please check it and maybe re-enable it in the future?

(I know that currently there's a migration happening and we'll soon(?) update to 0.19.4, so this issue I'm pointing may have to wait till all these finish first (or updating may fix it without any extra work)).

Thank you for maintaining this instance! :)

I am performing a migration that moves the images files from disk storage to object storage. During this migration the image back-end needs to be turned off, and so images will not be accessible.

It should still be possible to comment.

I am not sure how long this will take.

This is part of a few optimizations that I plan to do before I upgrade the instance to version 0.19.4.

EDIT: Update, June 17 06:08 UTC

The transfer is working, but, after 12 hours, only ~50 GB have been transferred to Contabo's object storage (rate of about 1.16 MB/s). This is a lot slower than I imagined, and, if this rate continues, it will take about 3 more days to transfer the remaining 300 GB.

I am not sure if this slow rate is to be expected for moving files to object storage, or if something is wrong. If any of you has experience with this I would appreciate some tips! I have also asked in the Matrix chat in case someone there can provide me some feedback as well.

EDIT: Update, June 18, 07:44 UTC

Migration is done!

272.16 GB of image data has been transferred to object storage. This took about 37 hours. This means that transfer occurred at a rate of 2 MB/s. From other admin's experience, this transfer was quite slow. I am making use of Contabo as my object storage provider, and I suspect that the speed of the transfer was limited on their end. Another admin reported that they used backblaze b2 as the object storage provider and they experienced much faster transfers. All of this should have no influence on how the site performs from the end-user's point of view, I am documenting this for other admins who learn from other's experiences by searching through lemmy.

Object storage is a much cheaper way to save files in the cloud. Before this, I have stored the image files into the same SSD disk where the instance lives (rented from serverspace.io). The cost of this disk space goes up as the disk space needs increase. At the current disk size of 400 GB renting that space was costing $36/month and increased $0.9/mo for every 10 GB.

Object storage is a specialized way of saving and serving files from the cloud. Object storage is much cheaper, at €6 for 500 GB (from Contabo), and so it is a much more scalable way of storing the instance's files. The only reason I did not do this earlier was because I was not sure about how to do it and kept pushing it back. But now, it's done! I would recommend other admins to do this as early as possible, as migrating many files is more of a hassle than migrating a few.

Istill need to do a few more tasks (moving the instance to a new server with a smaller disk, upgrading the postgres database to be compatible with 0.19.4, changing the pict-rs database format from sled to postgres, and then upgrading to 0.19.4). But first I will let the instance run for a few days with object storage to make sure nothing is breaking.

Thank you for your patience :D

I was curious if anyone knows anything about the large delay for content coming in from lemmy.world? There's a discussion over there in one of fediverse communities and apparently we're like a week behind in receiving data.

cross-posted from: https://mander.xyz/post/14134903

Sorry if this seems like a silly question but I have noticed over the last few months my feed(?) has started to act odd.

No matter what I do I don't see any posts from .world. I checked and mander does not seem to block .world (kinda why I liked this instance) and even weirder is how my feed gets filled with mostly .ml posts with almost no activity no matter how I sort.

This did not happen before and got me thinking, I don't even know how this works across federated instances.

Does anyone know:

• How does the sorting work on an instance? Is it all the same no matter what instance it is?

• Did anything change in the last few months, that would cause all .world (and I assume others) posts to not show?

• Other then changing instances what can I do to mitigate the weird slanted results?

Hello everyone,

A few people had a conversation in !fedigrow@lemm.ee about finding a new place to host a !dataisbeautiful community (see the thread here: https://mander.xyz/post/13861536)

We were thinking about mander.xyz as the theme of data seems to fit with the topics of the instance.

Would you be okay with us opening that community here?

I woke up and noticed that the server was down. I think that there were two different issues happening at once - one related to nginx, and the other related to a memory limit I recently set on a docker container. Issues are fixed now. Sorry!

I have just created a new community in Lemmy about Generative AI like GPT or Midjourney. The subjects are diverse: from news to development

I have become aware of an instance with widespread posting of pornographic drawings of cartoon characters that look like minors. I have added the instance to our block list.

If any user from this instance would like to discuss this action, I'm open to talk about it in the comments.

If not, great. I would prefer not bring any attention to this at all, but I want to be transparent about de-federating actions.

If you do enjoy this content and would like to visit the instance, you can find it at: burggit.moe

Mander has been upgraded to v0.18.4.

The most noticeable change appears to be the fixing of a bug that would cause some comment trees and comment reference links to not load properly. But if you notice something else, please let me know - or, even better, create an issue for it on github!

Lots of thanks to the developers 😀

Upgrade instructions

Follow the upgrade instructions for ansible or docker. There are no config or API changes with this release.

If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat.

TL;DR for anyone from Mander:

Small mander logo: in the bottom right quadrant, between the EU flag and Ramona Flowers. Seems like this one was done by @Sal@mander.xyz very early on in the event. Much later, near the end of the event, I just added the text above it.

Big Mander logo: check in the top half, near the center, to the right of the Swedish flag. Was planned out by yours truly (not knowing we already had the small logo), though @mookulator@lemmy.world / @mookulator@mander.xyz came by and helped out actually placing the pixels (thank you!). The outline/background around the text was done by various other users, including @Lumun@lemmy.zip , @verb@mander.xyz , and @angrath@mtgzone.com -- thanks for coming by to help beautify our logo!

Thanks for joining in! The canvas is now finished!

I’m going to be leaving the canvas up and read-only for a couple days, but not too long.

This was incredibly fun to host, thank you all for participating! ♥

Future Events

I’d love to make this a yearly event. Expanding from just Lemmy to the entirety of the fediverse aswell!

I’ll reuse this Lemmy community & the Matrix space for that event

If you have suggestions for future events, post them in a comment on this post, each suggestion as it’s own comment so people can vote on them

I reproduced our logo in pixel art, added our domain name in text, and I'm gonna start adding this to the Canvas.

The bottom right corner (where I'm starting) is located at 646, 205.

Come join me! And decorate this further if you'd like!

Edit: look like the picture is a little small because it's pixel art. You may want to download it and open it up in MS Paint or something then zoom in a lot.

Edit2: I found a mistake in my template: there's one extra gray pixel on the right side, diagonally up/left from the uppermost black pixel of the...uh...chelicera I guess.

Edit3: There are actually three extra gray pixels, the other two are to the right and above the one I just mentioned.

Hello all, I'm sharing this here because I think it is a fun and interesting initiative that users might appreciate knowing about.

The instance https://toast.ooo/ is running an event similar to Reddit's /r/place. Here you can find their post announcement. The canvas can be reached here: https://canvas.toast.ooo

If you are not familiar with /r/place: the idea is that every user gets to place pixels on a canvas. After placing a pixel, there is a 1 minute cool-down before you are able to place the next pixel.

To log-in, you fill-in your instance's name and username, and you are sent a code as a private message which you then use to authenticate. So the method of authentication does not expose your username and password combination to a third party.

I find it cool how third-party events like this one can be integrated into the decentralized Lemmyverse without requiring active input from instance admins.

I have been looking for one for a few day. I've got no result nor answer.

I thought that on an instance dedicated to nature and science, I would find one. But I'm starting to dispair. Where do you go to talk about food waste ?

(URL goes to /c/houseplants )

Where's the pixel art in the sidebar from?

Actually, where's all of the art from? But I'm specifically mentioning pixel art because I really like pixel art and I think this stuff is really cute!

EDIT: I did not expect the preview snippet to be so extraordinarily lengthy.

Is there a way to make opening links in new tabs a default behaviour?

This is a new problem for me that started a couple days ago. Using Jerboa and Firefox, I'm unable to post images on this instance. I am able to post images to the same communities using a different instance account. I am getting "network error" and Java errors (I'm unable to see the full error) while using Jerboa. On Firefox, I get an "image too large" error for 12 MB (edit: not GB, that'd be a huge image) images (not sure the limit) but "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data" at smaller image sizes. I was able to post images on this instance before this. My Jerboa app is up to date. Any solution?

Anyone else get kicked from the instance? I had to sign out due to api errors and now I can't get back in.

Web UI is all messed up, upvotes and OP's name and some other things. Works well when you are not logged in.
