This post has 11 comments on lemmy.world right now

https://lemmy.world/post/788282

but I can only see 2 of them when I'm browsing from tchncs

https://discuss.tchncs.de/post/368066

Upvotes are also different. Is there something broken in the federation with lemmy.world?

Update: It looks like it stopped federating right after I commented on the post.

Update 2: It's not only lemmy.world. One of my posts in a community on feddit.de never showed up there.

Update 3: feddit and lemmyworld are still on 0.17.4, while tchncs is on 0.18.0

Hi, würde gerne die Bilder, die ich hier bei pixel.tchncs.de hochlade auch in Lemmy (per Hotlink) teilen. Ist das möglich bzw. erlaubt? Andernfalls lade ich sie beim Hoster meines Vertrauens hoch und verlinke sie von dort.

Danke! 😊

As far as I see that instance is a far-right cess pool. Everything I've got from that instance were low-quality transphobic "news articles".

I'm only noticing this on tchncs.

The couple first posts on the "Hot" "Subscribed/All" sorts on tchncs seem to be "normal" hot posts, but after around 15 of those there are only weeks/months/years old posts.

I searched for issues on the repo and I found this which may have been applicable: https://github.com/LemmyNet/lemmy/issues/3125

However, it was fixed for 0.18, which tchncs is running, and theoretically update_hot_ranks should be a startup job, which I assume happened when updating.

Can something be done about this? Maybe cross-post this to [email protected] (though this should probably be done by our friendly admin)?

The amount of apps being developed for iOS / Android is getting really crazy now and new apps keep popping up every day. Updated list below:

• Artemis (iOS, Android, kbin, lemmy): link
• Memmy (iOS, lemmy): link
• Mlem (iOS, lemmy): link
• Morpha (iOS, lemmy): link
• Thunder (iOS, Android, lemmy): link
• Beyond (iOS, Android, lemmy): link
• Limbo (iOS, Android, lemmy): link
• Jerboa (Android, lemmy): link
• Slide (Android, lemmy): link
• Sync (Android, lemmy): link
• Unnamed (kbin): link

Most apps on the list are lemmy apps, meaning they don't work with kbin. Artemis is specifically designed to work with kbin, not sure if or when any of the other ones will go in that direction or become interoperable as there are some challenges with the kbin API at the moment. Having said that, a new API is in the works (https://codeberg.org/Kbin/kbin-core/pulls/357) so things should get better with time. Some of the apps are in very early stage of development so it may happen that they adjust OS availability and platform support.

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.

I hope that this game has made you reconsider your views on content moderation. Maybe you will decide to live with the nebulosity, but have more sympathy for the refs. Maybe you will decide that you would prefer to live with the consequences of less moderation. Maybe you will think really hard about decentralization (which is not a panacea). Maybe you will give up on social media altogether.

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

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 entirely, and switch to HTTP instead. This change was made much more urgent by the sudden influx of new users. @CannotSleep420 and @dessalines have been working hard for the past weeks to implement this change in lemmy-ui.

HTTP on its own is already more lightweight than websocket. Additionally it also allows for caching of server responses which can decrease load on the database. Here is an experimental nginx config which enables response caching. Note that Lemmy doesn't send any cache-control headers yet, so there is a chance that private data gets cached and served to other users. Test carefully and use at your own risk.

Two-Factor Authentication

New support for two-factor authentication. Use an app like andOTP or Authenticator Pro to store a secret for your account. This secret needs to be entered every time you login. It ensures that an attacker can't access your account with the password alone.

Custom Emojis

Instance admins can add different images as emojis which can be referenced by users when posting.

Other changes

Progressive Web App

Lemmy's web client can now be installed on browsers that support PWAs, both on desktop and mobile. It will use an instance's icon and name for the app if they are set, making it look like a given instance is an app.

Note for desktop Firefox users: the desktop version of Firefox does not have built in support for PWAs. If you would like to use a Lemmy instance as a PWA, use use this extension.

Error Pages

Lemmy's web client now has error pages that include resources to use if the problem persists. This should be much less jarring for users than displaying a white screen with the text "404 error message here".

Route Changes

Pages that took arguments in the route now take query parameters instead. For example, a link to lemmy.ml's home page with a few options used to look like this:

https://lemmy.ml/home/data_type/Post/listing_type/All/sort/Active/page/1

The new route would look like this:

https://lemmy.ml?listingType=All

Note that you now only have to specify parameters you want instead of all of them.

Searchable select redesign

The searchable selects, such as those used on the search page, have a new look and feel. No more inexplicable green selects when using the lightly themes!

Share button

Posts on the web client now have a share button on supported browsers. This can be used to share posts to other applications quickly and easily.

Lemmy-UI Overall look and feel

lemmy-ui is now upgraded to bootstrap 5, and every component is now much cleaner.

Special thanks to sleepless, alectrocute, jsit, and many others for their great work on improving and re-organizing lemmy-ui.

Database optimizations

Special thanks to johanndt, for suggesting improvements to Lemmy's database queries. Some of these suggestions have already been implemented, and more are on the way.

Query speed is Lemmy's main performance bottleneck, so we really appreciate any help database experts can provide.

Captchas

Captchas are not available in this version, as they need to be reimplemented in a different way. They will be back in 0.18.1, so wait with upgrading if you rely on them.

Upgrade instructions

Follow the upgrade instructions for ansible or docker.

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

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for almost three years. This is largely thanks to support from NLnet foundation.

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. No one likes recurring donations, but they've proven to be the only way that open-source software like Lemmy can stay independent and alive.

Independent services like tchncs are valuable and need money to run stable, so we can enjoy them. Consider donating if you can.

Asking because I remember similar from e.g. Okuna where a shiton of communities were created during the gold rush but many were left unmoderated for months until they eventually ceased.

And at what point would a transfer be considered by staff?

Lemmy is planning on having its 0.18.0 release tomorrow, and this adds compatibility for it.

We’ve upgraded lemmy.ml to use the new 0.18.0 back-end, so it was crucial that I got this jerboa release out ASAP to be compatible with it.

Yesterday I made a post in the football community located on lemmy.world (https://lemmy.world/c/football). Now when you look at the post from here discuss.tchncs.de/c/[email protected] it has 0 comments and 1 upvote:

https://discuss.tchncs.de/post/183785

Whereas it actually has 1 comment and 4 upvotes on the Remote instance:

https://lemmy.world/post/343210

Because on discuss.tchncs.de the comment doesn’t show up, I obviously get no notification nor can I respond.
Anyone got an idea?

There has been a big spike in growth over the last 2 days, and some rather suspicious new instances appeared out of nowhere with thousands of new users, even though there is close to no activity in any of them.
Could all those be bots? Would it be smart to block those instances preemptively?

kbin.social shows up in the instances list (https://discuss.tchncs.de/instances), but I'm having trouble with [email protected]. I couldn't get it to show up in search until I searched for the full URL (https://kbin.social/m/nfl). Once it did, I can join, but there's no content. See here: https://discuss.tchncs.de/c/[email protected]

Edit: actually, one post has now shown up, but not the rest.

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, Email, Clouds, Websites and stuff and lots of headroom), to a Hetzner serverauction baremetal thing with an Intel Core i7-7700, 2x SSD M.2 NVMe 512 GB, 64 GB DDR4 Mem, 1 Gbit Networking in Finland.

I plan to migrate today as soon as the thing is ready and configured. There will be a downtime of up to 1 hour.

Lemmy will share its seat on the machine with the tiny Calckey instance that was deployed around the same time.

Increased monthly cost: around 40 EUR

Note on the thing Meta is developing with ActivityPub federation support:
I am not a friend of Meta and am happy to keep it out of my life an off of my servers. However there are lots of rumors and barely any confirmed informations around the project. I will act accordingly once more is known. I also won't make any exceptions in terms of enforcing our rules. However i won't participate in signature lists for pre-blocking everything Meta and run around in circles, screaming in panic.

Kann man als Mod eigentlich irgendwie sehen, wer eine Community subscribed hat, um evtl. jemande/n zum Mod zu machen?

Kann kein Bild posten... Merkwürdig. Auch auf dem Handy nicht...

{msg Error storing objects, files null}

So sinngemäß.

Offensichtlich plant Meta den Einstieg ins #Fediversum, indem man eine "kompatible", Instagram-ähnlich App hierzu anbieten will (Codename "Projekt 92"). Offensichtlich gibt es Instanzen, die einen Datenaustausch mit Meta nicht wollen, und deshalb bereits jetzt durch eine virtuelle Unterschrift gegen eine Förderierung mit Meta-Instanzen abgegeben haben. Gibt es auf tchncs.de dazu eine Meinung oder eine Diskussion?

I can currently not see my own posts on my profile. I have 3 posts, it says I have 3 posts, but the list of posts no matter how I sort it is empty. Is this a bug? Did we block another instance maybe?

"Für Deutschsprachige gibt es die Lemmy-Instanzen Feddit und tchncs, ..."

When I go to "All" and sort by "Hot", I've been seeing the same posts there since a day now, and most posts there are 2+ days old.

When I do the same on my accounts on other instances, the list constantly changes and most posts are minutes old.

Is something broken and not updating on tchncs?

• Number of votes for posts and comments differ from instance to instance (sometimes drastically, 300 vs 30 for example)
• Number of comments differ from instance to instance (meaning you can "miss" some comments on one instance, because they simply aren't there)
• Order of posts and comments differ from instance to instance (even with the same sorting option)
• If you leave the post open in the tab, you can come back to that tab later, only to see that it is a completely different post than the one you opened, but the comments are still from the original post.
• On the front page, more post will sometimes randomly start loading from the top, those posts usually come from a specific community and are old posts (sometimes very old)

Does anyone else experience this?
Are those simply bugs, "features", problems with specific instances, or just the shortcomings of this kind of platform?
