What is Lemmy?

Lemmy is a self-hosted social link aggregation and discussion platform. It is completely free and open, and not controlled by any company. This means that there is no advertising, tracking, or secret algorithms. Content is organized into communities, so it is easy to subscribe to topics that you are interested in, and ignore others. Voting is used to bring the most interesting items to the top.

Major Changes

This version fixes the problem of comment context not loading properly. It also fixes a couple other bugs.

Support development

@dessalines and @nutomic are working full-time on Lemmy to integrate community contributions, fix bugs, optimize performance and much more. This work is funded exclusively through donations.

If you like using Lemmy, and want to make sure that we will always be available to work full time building it, consider [donating to support its development](https

As of deep last light (cest), the error was identified and tchncs started to inform other servers about the events they were missing out on. It wasn't processing one of the outgoing queues correctly due to a well hidden typo in a configfile – causing one of the federation senders not identifying itself correctly.

You may run into a few recent messages that can't be decrypted, but otherwise everything federation related should be back to normal.

Sorry about this mess and thanks to everybody who has helped in identifying the issue.

Well hello again, I have just learned that the host that recently had both nvme drives fail upon drive replacement, now has new problems: the filesystem report permanent data errors affecting the database of both, Matrix server and Telegram bridge.

I have just rented a new machine and am about to restore the database snapshot of the 26. of july, just in case. All the troubleshooting the recent days was very exhausting, however, i will try to do or at least prepare this within the upcoming hours.

Update

After a rescan the errors have gone away, however the drives logged errors too. It's now the question as to whether the data integrety should be trusted.

Status august 1st

Well ... good question... optimizations have been made last night, the restore was successful and ... we are back to debugging outgoing federation :(

The new hardware also will be a bit more powerful... and yes, i have

Just in case we have people here who could not see the infobox on the statuspage due to adblockers :)

Major Changes

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%. Special thanks to @phiresky for their work on DB optimizations.

The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing

This instance was updated a little while ago.

You might have heard of the recent security incident on some instances – that specific xss fix had been added to this instance in advance. However, there are no custom emojis yet, which was the source of that incident. But .... I'll likely add some soon. :)

Major Changes

This release includes major improvements to performance, specifically optimizations of database queries. Special thanks to @phiresky, @ruud, @sunaurus and many others for investigating these. Additionally this version includes a fix for another cross-site scripting vulnerability. For these reasons instance admins should upgrade as soon as possible.

As promised, captchas are supported again. And as usual there are countless bug fixes and minor improvements, many of them contributed by commu

Hey there, many of you worried after recent registration bot waves on other instances and now after the temp captcha removal for this Lemmy release.
It was fine until now, but it looks like the bored kids with their bots have now found this server. Approval of new signups is now required again. Especially sad as this does not scale well.

HTTP API instead of Websocket

Until now Lemmy-UI used websocket for all API requests. This has many disadvantages, like making the code harder to maintain, and causing live updates to the site which many users dislike. Most importantly, it requires keeping a connection open between server and client at all times, which causes increased load and makes scaling difficult. That's why we decided to rip out websocket ent

Hello there friendly users!

Update 3:50pm CEST
The container has been moved, most work on the new host has been completed. There are some permanent data errors on the original storage pool, but it does not like it affected this linux container. Please give DNS and federation a moment.

Some (but only a few) of you have experienced an outage today around 5-8am CEST. This – as far as my current findings go – happened due to a filesystem panic. So far, i only experienced such a thing on virtual servers with a certain amount of load.

Even tho relatively speaking, i didn't feel like there was much to worry about with the current setup and its utilization, i feel like when looking at a potential second wave from Reddit, this instance should be prepared – so i just did a thing:

What we are moving to

We will be moving from a Netcup RS 4000 G9.5 KVM with 32 GB memory and 10 dedicated EPYC cores, *(that was meant for various smaller tchncs services such as XMPP,

Update June 11: (local) media is now being cached by the webserver. This is important to keep the costs low after migrating to object storage. Lemmy implements media in an uncommon way and i had to adapt. If you spot weird behavior for (local) media, please drop a comment.

Update June 10: to keep costs low, the new media location needs caching. This is currently being worked on and may or may not result in a few seconds of unavailable media.

Original post:

It is time to migrate the media over to object storage and yes, i suppose i should have done this in the beginning. 😇

This will take a few minutes while the underlaying mediaserver needs to be down. :)

Refreshing the page is not recommended 😅

I’ll tweak a thing or two today to ensure the current machine will be able to handle that ever growing wave, as not only the known network grows, the line of people trying to join the instance keeps growing as well (welcome!).

A few seconds of downtime are to be expected as changes require very short restarts of services. Don’t worry this is expected to be so quick, most of you won’t even notice.

Since it took me a second as well, i thought, i'd better share this with you:

If you want to see a bigger version of an image, you don't need to open the thread (in fact it wouldn't even help).

Just click on the small tile with the image and a bigger version will appear.

...because I find that it can be confusing... if you search for your Lemmy browsertab, I assume, you'll look for that mouse, not for the tchncs logo. 🐭

Feel free to add your opinion on this. (if you still see the tchncs logo in the navbar, refresh the page)

Oh noes, that short community list 😱 – but hey, some have been shown to the instance already! 🎊
An instance needs to learn the network either organically from interactions or by getting pointed to nice places of the fediverse.

Finding a community

You might have seen the instancelist already. You can view their communities and subscribe to them from tchncs. Also check out browse.feddit.de for finding all teh nice communities across instances.

Syntax

The syntax for a community is !community.
The syntax for a remote community is !community@server.xyz
The searchbox also understands full links like https://lemmy.ml/c/unixporn

Show this server a community:

Note: make sure you are searching the fediverse. Do not filter for local, which might be your default!

1. Go to the search and look up a remote community that you either found on the network or simply guessed.
2. The server wi

About the vote

Since a little while, you can vote for and suggest, what could be next for tchncs.de – use this thread to discuss suggestions or just use the Nextcloud poll in the link. :)
Most services will be tried without full commitment within the first while, because it is often unclear how well they scale, can be moderated or will be used. However i am not good at not continuing things... need to improve on that front.

What you can do here

Find the missing link, but also discuss certain software before voting or maybe for giving your vote (or submission) more weight – or just use it as a forum to find cool stuff.

What we are testing now

• Calckey (intended for production)
• Lemmy (intended for production)
• Vikunja
• OpenTalk (now in production)
• Bookwyrm (now in production)

Considered for testing someday soon

• Mobi

Feel welcome to use this post for testing purposes, feedback on the instance and to say hi!

Since the playground model wasn't really that good (it prevents users from making things their home), I've decided not to announce this instance to be in playground/testing mode. Instead, i'll simply try to make it work and hope that it won't become an administrative nightmare.

However – things are looking quite good so far.

In the background i am currently trying to determine whether the current location is powerful enough midterm, if not, there will be a quick and quiet maintenance to move the thing to a more fitting place (looking at the potential upcoming wave from Reddit). Also there are some smaller things in the background still being worked on, but they shouldn't affect users.

tl;dr have fun, if everything goes well, this will be a permanent place for people to enjoy – i hope. �*
