General Lemmy.Cafe

due to the offending user being banned from the federating instance before the post was removed? example

edit: i recognize this is not a local issue and may be more of a lemmy problem. wondering if anyone has any experience or thoughts cuz its weird to have awful stuff hosted on one instance even though it was banworthy elsewhere.

edit 3: removed edit 2.

Recently I was trying to reply to a comment and it wouldn't post the reply. Today I also wanted to upload a meme but the image wouldn't upload, so I resorted to using catbox.moe. Even with that, it still insisted on generating its own broken image and the thumbnail didn't generate either

UPDATE: Apparently only GIFs and replies are broken. Uploading a JPG or PNG works fine

It's the "silently" part that's the issue. I acknowledge that lemmy.cafe is entitled to defederate from whatever servers the administration pleases, but lemmy.ml still houses some of the largest communities in the Lemmyverse on some topics, and a heads-up that it was being blocked would have been appreciated.

The upgrade has gone through smoothly and everything seems to be running smoothly.

The performance looks to be better on the backend, time will tell if the memory leak issue is actually solved. So far, though - so good!

Lemmy Cafe will be having its database upgraded.

Reasons

• Pict-rs is expecting PostgreSQL 16. It's running fine now, but it might not be at some future point.
• PostgreSQL 15 has a bug that requires jit to be turned off - otherwise DB keeps consuming all the memory available on the system and then some. In the end it gets culled by the kernel. This has performance as well as reliability issues. While turning jit off has remedied the constant failure, it has also made the database a bit slower. I prefer squeezing out as much performance as possible :)

Plan

• Point nginx to the maintenance page
• Shut down PostgreSQL 15
• Run the upgrade tool
• Start up PostgreSQL 16
• Point nginx to lemmy

Expected downtime

About an hour, if things go well. More if not so.

Will try to keep the maintenance page updated.

The process went through smoothly. I have also used the opportunity to split up a singular lemmy container into individual tasks - this has enabled a seemless upgrade process with no downtime, bar a few process quirks I need to work out.

There have been some federation fixes merged into this release, so the situation should definitely be improving overall!

I will make a more detailed write up of the whole setup later on, other admins might find it useful. Or not.

May your families grow strong and your presents plentiful!

The upgrade has reset the JWT, so you'll have to login again on your device as well as set up 2FA again.

Enjoy the new features!

Pun intended 😁

Just wanted to reiterate, my stance hasn't changed since last declaration.

If facebook starts funny business with extra domains - those will be added asap.

It's been a long one, but finally the database is clean. In the end the cleanup took <20 minutes, but getting to it took me most of the weekend.

Sorry about flaky performance, it should be back to normal.

Migrated email into a dedicated self-managed solution, but it was at the end of the month, haven't included it here.

Minor update in prep for the biggin. Pictrs was also pushed up to 0.4.4

The main feature being a fix the really nasty libwebp vulnerability.

I've just received an email that has links to what looks like some polish url redirect site. I suspect this is limited to admins as, by default, lemmy does not come with an email service.

Needless to say - don't click random links!

Stay safe, peeps!

I'm chuffed to bits to have finally had enough time to set it up externally. Google is no longer outright rejecting us!

And by externally I don't mean succumbing to the behemoths - it's all self managed!

I've seen a post recently about someone struggling hosting Lemmy on DigitalOcean and sending out verification emails. If you need help with config or would like to simply use lemmy.cafe's setup - feel free to reach out!

First donations!

Also migrated pictrs from file to object storage, but have not been invoiced, yet. I suspect it's the low amount (<$1) and will probably keep carrying over until some threshold is reached.

Signed up on LiberaPay. Stripe is slow to activate the account.

Lemmy storage was growing quite quickly on the small VPS nodes, had to upscale a bit.

Sorry about it, it seems like after having nuked the CSAM incident community lemmy-ui has freaked out again about the site logo. Fixed it for now, will keep a close eye on the web UI.

Apps were not affected.

Following the recent CSAM spam the upload size has been further reduced to 50kB.

This might impact community/profile banners, in which case I propose getting in touch and we'll sort it out on a case by case basis.

Apologies for the downtime.

DigitalOcean has been experiencing a network outage and as such Lemmy Cafe is also affected.

Incident page suggests it should be resolved now.

Current infrastructure costs are ~30 GBP a month. Not crazy expensive, but something that has potential to grow in the future.

Expense breakdown:

• Lemmy UI+backend: 14GBP/month
• Lemmy DB: 14 GBP/month
• Domain: ~2 GBP/month
• Traffic is not reaching the limits at the moment, no extra cost
