I was informed about something going wrong here and investigation showed that it's worse than I thought. My Contabo Object Storage started claiming it's full, even though it's only half-full. I opened a ticket to tell them to fix their shit, but knowing their speed, it might be a few more days :-/

That's what I get for choosing the budget services...

For the past couple of days I can't seem to be able to post on communities other than those on dbzer0. Just says error 500.

• My app isn't an issue, posted through alt on the same app. Also tried from a seperate app - same result.

• Not banned or anything from the community, checked modlogs. Also mod one of the communities I can't post on. [email protected]

• Tried posting on communities from several instances, same result.

What's going on here? Anyone have an idea?

Simply mention @[email protected] with the text "draw for me " and then the text that you would like it to draw and I will draw you an image matching your prompt, post it in this community and then reply with a link to each image! Optionally you can provide a "style:" as well. Example: [@[email protected]](https://lemmy.dbzer0.com/u/aihorde) draw for me a beautiful night style: fantasy

This is a free service provided through the AI Horde. Please consider onboarding your own worker onto the horde if you enjoy this bot!

Source Code

New version was released, so we've upgraded.

Not much more to say, Have a Lemmy Gandalf

Upgrade posts are a good reminder to help us cover server costs. Currently we're not making enough to pay for the infrastructure. Click one of the images below to support us.

I am curious what can be done about the Lemmy.World era of botting corpo comments to protect their investments?

Anything remotely federated w/ LW has a massive hard-on for corporations (anti-piracy boot-lickers only added us back when we had the largest community in the fediverse), racism (you ain't american, you aint right), a desire to troll/argue in bad faith, and a general "fuck you, I have 500 accounts to down-vote with."

I myself have over 60 accounts on Lemmy.World; and because of that, I am 100% certain somebody has a type of SMM portal to scan for keywords and upvote/downvote accordingly.

Don't believe me?

Go post about Apple, Facebook, Tesla, or any other 1% owned entity, and watch which accounts upvote/downvote in less time than required to read the post.

I've been trying to create a post for a while now, but I keep getting the same error.

Check the release announcement here

Easy-peasy upgrade. Just one small hiccup as the reverse proxy needed to get the good ole boot.

Nothing more to say. Carry on.

I was just banned from [email protected] with the following modlog: Harassment. Do not come to random communities for your grudges, Use the rerport button when actual issues occur. I like ADHD memes, it wasn't a random community. But that aside, Lemmy is designed so that I can't follow this advice, because banned users cannot submit reports. So I am doing my best to follow the instructions as closely as possible, and submitting this post in lieu of a report. Stamets repeatedly called me a slur directed at people with NPD, which I have, off-community and defended it on dbzer0. MetaCubed also called me a slur after its status as a slur was pointed out. I ask for instance bans for both of them, because slurs directed at members of a marginalised group from outside are obviously in violation of the anarchist code of conduct. I would be submitting this as a literal report if I were able.

Our 6-months goal for 2023 was reached and exceeded, so as promised I have donated the overflow to lemmy development. Now it's time to open the new goal. So do chip in to support this instance!

Why can't I follow communities from this instance

I recently attempted to follow communties on this instance from mastodon and they all say pending. Does anyone know why this is happening? Is it possibly related to the federation problems of 0.19?
I made a github issue but I'm not sure if the Devs will help or not since on one hand it's not their software but on the other hand it seems like a federation issue. 🤷​

@div0 @db0

Hey peeps, I have upgraded to lemmy 0.19.1 which should fix any federations issues and the read-posts bug.

As I said, I have also replaced the abandoned tesseract frontent, with a self-hosted voyager frontend. You can find it at https://v.lemmy.dbzer0.com. This should allow you to keep your credentials extra safe, even when using a mobile device. You can add it as an mobile "app" via your browser.

Unfortunately almost at the same time I started this upgrade, we started experiencing some network issues which I've been troubleshooting for the past few hours and I can't figure out. So at this point I'm thinking this is caused by this ongoing OVH maintenance as my server do not appear under load, and the request timeouts appear random.

I'll keep investigating and let you know if the status changes for the better.

Update: I'm fairly certain the timeouts are due to OVH networking at this point, so I'm doing a workaround. Things should improve within 4 hours. Update2: Issue should be resolved currently.

Hey peeps, it was just brought to my attention that Tesseract has been discontinued. I was one of the few instances which was hosting Tesseract as it had some integrations with Fediseer but unfortunately it seems I need to remove it.

I decided to replace it with Voyager instead. I'm going to leave things up for a day or so to let you update your bookmarks, but soon t.lemmy.dbzer0.com and tesseract.lemmy.dbzer0.com will be removed and v. and voyager. will be added.

I have now upgraded the Divisions by zero to Lemmy 0.19.0. I haven't seen any issues, but of course you will have to re-login.

Please check the new features here

I have also updated Pythörhead to be able to handle the new authentication (as well as the old), so if you're running a bot, make sure to update your Pythörhead dependencies.

Now is also a good time that you can support the running of this server. If you just want to support this instance, please use Ko-fi and you can get a custom emoji here. If you want to support my general development efforts as well (Lemmy, Pythorhead, Fediseer, Tagginator etc) feel free to use my liberapay

I am working on my dev instance. Once that plays out OK, I'll need to update pythorhead to handle the new authentication, then I'll be upgrading this instance to 0.19.0.

I don't have an exact time, so if you see this instance down for a bit, you know what's up. You know how it is here...

I want to make our little corner of the fediverse a bit more unique, so I thought it might be a cool idea to take some classic memes and use the AI Horde to customize them for our respective themes.

First one I started is "You have no power here" which I wanted to post multiple times as a response for someone moralizing about piracy or anarchism etc

I have thus created two versions of it.

:nopower_hacker:

:nopower_pirate:

Please suggest other meme templates you think would fit into this space and I will do myself to create versions to use here.

Our little instance is closing to 6 months of operations and it occurs to me I never really asked for some open feedback from our peeps. So I wanted to start a discussion to see your concerns and comments in general. So tell me, in the context of the divisions by zero, what bothers you, what pleases you, what would you like to see improved.

Feel free to share your thoughts about anything.

Am i missing something or is lemmy ignoring the chosen filters(community, activity, page) when im returning from a post back to the list of posts(using the back button)? The filters themselves are selected but the content isnt filtered.

It seems image uploads are not working atm. I contacted my Object Storage provider about it and will keep in in the loop

EDIT: Looks like the defederation has been reversed. @db0 Thank you for looking into this quickly.

A commenter in the linked post is suggesting that dbzer0 automatically follows lemmy.world's block list. That seems like kind of a bad idea? In this instance it seems like the LW admins are just following the decision of lemmy.ml's tankie admins, and tankies gonna tank.

The error:

Here's the image I was trying to upload: (uploaded thru imgur)

I was trying to upload the image to c/[email protected]

I found a github issue for this, but the discussion seems to point towards it being on your end or lemmy.world's end.

I am excited to announce that I have just finished deploying a new wiki service tied to lemmy.dbzer0.com.

https://wiki.dbzer0.com (Ignore the certificate errors for now, it some leftovers from the downtime yesterday. Will be fixed soon)

The most cool part of this setup, is that while anyone can read, only users who have an account in lemmy.dbzer0.com can edit. This should nicely prevent spammers from causing issues, and can help us tie edits to accounts here. if your account gets banned in lemmy.dbzer0.com, you also lose access to edit the wiki as well!

To manage that, you simply need to register an account on the wiki, then write that account on your bio here. The frontpage of the wiki provides the relevant instructions.

So if you needed a place to add official pages about your community with info, now you have the place!

Just a quick update for people using pict-rs workers, to grab the latest release, and set the 2 new variables as they want them

SCAN_BYPASS_THRESHOLD (default 10): If this amount of images are waiting for scanning, pictrs-safety will start retuning "OK" for each new scan after that. This will prevent overloaded workers causing all further uploads from bouncing.

MISSING_WORKER_THRESHOLD (default 5): If this amount of seconds have passed since a scanning worker last checked in, start returning "OK" for each new scan after that. This will prevent a crashed worker from causing all images to bounce.

You can set either of these to 0 to turn off their functionality

In the past months, there's a been a issue in various instances where accounts would start uploading blatant CSAM to popular communities. First of all this traumatizes anyone who gets to see it before the admins get to it, including the admins who have to review to take it down. Second of all, even if the content is a link to an external site, lemmy sill caches the thumbnail and stores it in the local pict-rs, causing headaches for the admins who have to somehow clear that out. Finally, both image posts and problematic thumbnails are federated to other lemmy instances, and then likewise stored in their pict-rs, causing such content to be stored in their image storage.

This has caused multiple instances to take radical measures, from defederating liberaly, to stopping image uploads to even shutting down.

Today I'm happy to announce that I've spend multiple days developing a tool you can plug into your instance to stop this at the source: pictrs-safety

Using a new feature from pictr-rs 0.4.3 we can now cause pictrs to call an arbitary endpoint to validate the content of an image before uploading it. pictrs-safety builds that endpoint which uses an asynchronous approach to validate such images.

I had already developed fedi-safety which could be used to regularly go through your image storage and delete all potential CSAM. I have now extended fedi-safety to plug into pict-rs safety and scan images sent by pict-rs.

The end effect is that any images uploaded or federated into your instance will be scanned in advance and if fedi-safety thinks they're potential CSAM, they will not be uploaded to your image storage at all!

This covers three important vectors for abuse:

• Malicious users cannot upload CSAM to for trolling communities. Even novel GenerativeAI CSAM.
• Users cannot upload CSAM images and never submit a post or comment (making them invisible to admins). The images will be automatically rejected during upload
• Deferated images and thumbnails of CSAM will be rejected by your pict-rs.

Now, that said, this tool is AI-driven and thus, not perfect. There will be false positives, especially around lewd images and images which contain children or child-topics (even if not lewd). This is the bargain we have to take to prevent the bigger problem above.

By my napkin calculations, false positive rates are below 1%, but certainly someone's innocent meme will eventually be affected. If this happen, I request to just move on as currently we don't have a way to whitelist specific images. Don't try to resize or modify the images to pass the filter. It won't help you.

For lemmy admins:

• pictrs-safety contains a docker-compose sample you can add to your lemmy's docker-compose. You will need to your put the .env in the same folder, or adjust the provided variables. (All kudos to @[email protected] for the docker support).
• You need to adjust your pict-rs ENVIRONMENT as well. Check the readme.
• fedi-safety must run on a system with GPU. The reason for this is that lemmy provides just a 10-seconds grace period for each upload before it times out the upload regardless of the results. A CPU scan will not be fast enough. However my architecture allows the fedi-safety to run on a different place than pictrs-safety. I am currently running it from my desktop. In fact, if you have a lot of images to scan, you can connect multiple scanning workers to pictrs-safety!
• For those who don't have access to a GPU, I am working on a NSFW-scanner which will use the AI-Horde directly instead and won't require using fedi-safety at all. Stay tuned.

For other fediverse software admins

fedi-safety can already be used to scan your image storage for CSAM, so you can also protect yourself and your users, even on mastodon or firefish or whatever.

I will try to provide real-time scanning in the future for each software as well and PRs are welcome.

Divisions by zero

This tool is already active now on divisions by zero. It's usage should be transparent to you, but do let me know if you notice anything wrong.

Support

If you appreciate the priority work that I've put in this tool, please consider supporting this and future development work on liberapay:

https://liberapay.com/db0/

All my work is and will always be FOSS and available for all who need it most.

After lemmy.fmhy.ml shut down due to Mali just withdrawing all domains without notice, their new site never quite got the same traction as the old one, and it seems the technical issues kept piling up as well, including a catastrophic failure of a VM or something I think.

Today it seems their admins decided to throw in the towel, and are migrating to the divisions by zero as their primary home.
