  • Thinking of moving to tchncs for mastodon

    I’m thinking of moving to tchncs on mastodon (moving from floss.social) because for me floss.social limits some big instances a bit too much, causing me to be unable to see a lot of replies and posts.

    Is there a way for me to check which instances tchncs has “limited”?

    Limited is different from blocked. You can still follow users from limited instances and open their posts. They just won’t appear in trending or in replies.

    Thanks in advance and thanks for the great lemmy instance! :)

  • Potential decline of tchncs donations

    Well hello there, I hope you are having a good time and that apart from the shaky recent update, discuss.tchncs.de serves you well! 🚀

    > ### tl;dr > tchncs is doing wonderfully in terms of donations, but I have reason to worry about an ongoing decline. Please don't feel pressured but if some of you would help looking out that it doesn't fall below a certain threshold, that'd be amazing. :)

    Many of you are already using tchncs services elsewhere, but for those of you who are new, I'd like to briefly mention that this service is powered by donations of its users. By donating a small monthly fee, you ensure that I will be able to keep paying for the infrastructure and its upgrades, as well as investing my time, trying to keep the thing rolling.

    Donating is 100% voluntary and not each and every one of you need to do it – also for now, there is no critical need for new donors.

    If that's the case, why am I even pointing this out?

    For a couple of months, our dear Elon (and later /u/spez) gave us not only waves of new users, but also motivated them / existing users to boost donations quite a bit. In fact, it is kinda unreal how much you kind people have donated to tchncs over the time.

    The server-costs have increased and unlikely will go down soon again. Even tho it happened before, the past month was quite weak compared to the previous trend. Of course it is still much more than many most fediverse admins sadly have to deal with(!), but also this month started weaker than usual and I worry that this time it might become a new trend.

    At tchncs.de/donate, I give you (maybe too) deep insights about the tchncs funding situation. Here you have what I just wrote as a screenshot:

    🖼 **very bright for darktheme screenshot of the previous months in donations** 🖼

    !Donation vs expense screenshot from july 12, 2024 Screenshot from july 12, 2024

    There is also tracked workhours on the site and together they even form dynamic goals with some hacky bash scripts. 😁

    So what do I ask for?!

    If, and only if you can afford it and if you really want to, please consider checking from time to time as to whether tchncs currently achieves goal #1 and ideally goal #2 (hw upgrades). It is important to keep a buffer for new hardware. And if not needed for new hardware, you are helping your fellow admin (me) with day to day expenses and ideally, savings for bad times.

    ...so that's all, this got longer than anticipated, sorry for that. Please do not feel pressured, as of now it's all fine. Just trying to make sure it stays this way. ✌

    This time no crosspost of the original statement in [email protected] because somehow the content is lost as I select the community 😅 I hope that this is just a small bug and that otherwise everything is healthy. Image proxying is not in place yet. I will have a closer look at the now possible setup changes soon™.

  • [✔ DONE] Database maintenance / Lemmy update – june 10 @ 18h CEST

    Normally I do not shut down services in order to perform updates, but the new Lemmy release requires a newer version of the PostgreSQL database server, which in turn requires a migration of the very cluster. If nothing special is hindering it (this happened with the Synapse Matrix server recently), this will be done quite quickly by just linking to the newer Postgres version (this is a feature of Postgres itself), otherwise it might take an hour or two.

    This will also affect the Firefish microblogging instance under https://procial.tchncs.de

  • [DONE] discuss.tchncs.de – Media Maintenance – 9PM CEST

    Adjustments and updates are planned to the pict-rs instance (this is the software Lemmy uses in the background for handling media). I will need to stop it for a few minutes. Lemmy itself is expected to run without any interruption – without the media tho. 😉

    Don't worry, if everything goes to plan, it will be done very swiftly. 🚀

  • This account is being verified

    Whe using my discuss.tchncs.de account with the app Jerboa on my Android phone, I get a message > This account (silmaril) is being verified

    and things don't work, whenever I try to use certain functions, eg. listing my saved postings.

    If I continue trying, the message changes to > Failed to connect to instance (https://discuss.tchncs.de/)

    General reading of posts still works.

    So I am wondering if there is something I still have to do in the verification process of my account?

    This might just be some bug in the app or incompatibility between app and server - but before digging deeper into this I wanted to check if there is a known solution.

  • Ableism in the Signup Process

    Hello comrades! I am new to the world of reddit alternatives and have been interested in exploring welcoming anti-capitalist communities. I want to see a post-capitalist world in my lifetime, which means we are going to need to be open to new comrades of diverse backgrounds and abilities. With that in mind, we need to talk about the problematic signup process. In question here is the all important Completely Automated Public Turing test to tell Computers and Humans Apart every user must engage with in order to join the community. The current captcha process is very difficult for those with divergent visual abilities. As someone who relies on accessibility tools to interact with the digital world, I call on the techncs community to address the problematic choices in the sign up process. Additionally, consulting people with different abilities for input on technical architecture is a must to promote diversity in the community.

  • Often getting comments failing to load (both on mobile app and desktop)

    Hey,

    I'm noticing that I get many broken comment chains and comments failing to load. Is that just for me or does anybody else experience issues. I guess, it started when I was updating the mail address linked to this account a couple weeks back. The token I got with the email to verify my address was rejected (Invalid token) and since then, I'm having issues. My settings show the correct email and I cannot send a new token to verify (it says nothing about verification status). It was, probably incidentally, at the evening of when the lemmy update got installed onto this instance, so maybe I've chosen a bad time for the mail change.

    Here is a thread that showcases my problem:

    Logged out:

    (Clicking on more comments does nothing)

    Maybe someone knows what's wrong.

  • My comments aren't federating

    I've made 3 comments in the past 2 days but none of them show up if I look at the home instance of the communities they're on. They're all on lemmy.world, but I see comments from other instances in the threads so I don't think the problem is on their end.

  • No comments from Feddit

    I‘m aware of the current federation issues that might also be the reason for this issue but I noticed that while federation of posts from feddit.de works sometimes as well as posts and comments from other instances no comments from feddit.de are syncronised at all.

    It might be better to ask there but as I do not have an account there I thougt I first ask here if this is already known. Does somebody else also have this problem?

  • Seems like federation between this instance and others is broken since the 0.19.0 update

    Is it just me or is federation broken on this instance? For example, take this post I made in [email protected] on this instance:

    https://discuss.tchncs.de/post/7934396?scrollToComments=true

    It shows a post being downvoted with no comments. However, on lemmy.world:

    https://lemmy.world/post/9689389?scrollToComments=true

    It's shown as one of the top posts on politics with 6 comments and 66 upvotes.

    I'm hoping this will be resolved soon and thank you admins for all the work you do on this instance 😘

  • Broken 2FA even on 0.19.0

    When the server upgraded to 0.19.0 and everyone's 2FA was reset, I again setup my 2FA. It accepted my code and 2FA was enabled. I tried to login again but it said multiple times that the code generated by the app was invalid. I try to disable this multi factor authentication but even that won't work since it asks for the TOTP code which it marks as invalid. How is a TOTP code generated by Lemmy's link and accepted by it's servers to validate 2FA in the first place be invalid?

    I am effectively now logged out from this account of mine because I can't sign into a new session and if I logout of this session, then boom, this account of mine is as good as dead.

  • tchncs has been updated to: Lemmy v0.19.0 Release - Instance blocking, Scaled sort, and Federation Queue

    Crossgeposted von: https://lemmy.ml/post/9347983

    > ## 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 release is very large with almost 400 commits since 0.18.5. As such we can only give a general overview of the major changes in this post, and without going into detail. For more information, read the full changelog and linked issues at the bottom of this post. > > ### Improved Post Ranking > > There is a new scaled sort which takes into account the number of active users in a community, and boosts posts from less-active communities to the top. Additionally there is a new controversial sort which brings posts and comments to the top that have similar amounts of upvotes and downvotes. Lemmy's sorts are detailed here. > > ### Instance Blocks for Users > > Users can now block instances. Similar to community blocks, it means that any posts from communities which are hosted on that instance are hidden. However the block doesn't affect users from the blocked instance, their posts and comments can still be seen normally in other communities. > > ### Two-Factor-Auth Rework > > Previously 2FA was enabled in a single step which made it easy to lock yourself out. This is now fixed by using a two-step process, where the secret is generated first, and then 2FA is enabled by entering a valid 2FA token. It also fixes the problem where 2FA can be disabled without passing any 2FA token. As part of this change, 2FA is disabled for all users. This allows users who are locked out to get into their account again. > > ### New Federation Queue > > Outgoing federation actions are processed through a new persistent queue. This means that actions don't get lost if Lemmy is restarted. It is also much more performant, with separate senders for each target instance. This avoids problems when instances are unreachable. Additionally it supports horizontal scaling across different servers. The endpoint /api/v3/federated_instances contains details about federation state of each remote instance. > > ### Remote Follow > > Another new feature is support for remote follow. When browsing another instance where you don't have an account, you can click the subscribe button and enter the domain of your home instance in the popup dialog. It will automatically redirect you to your home instance where it fetches the community and presents a subscribe button. Here is a video showing how it works. > > ### Authentication via Header or Cookie > > Previous Lemmy versions used to send authentication tokens as part of the parameters. This was a leftover from websocket, which doesn't have any separate fields for this purpose. Now that we are using HTTP, authentication can finally be passed via jwt cookie or via header Authorization: Bearer <jwt>. The old authentication method is not supported anymore to simplify maintenance. A major benefit of this change is that Lemmy can now send cache-control headers depending on authentication state. API responses with login have cache-control: private, those without have cache-control: public, max-age=60. This means that responses can be cached in Nginx which reduces server load. > > ### Moderation > > Reports are now resolved automatically when the associated post/comment is marked as deleted. This reduces the amount of work for moderators. There is a new log for image uploads which stores uploader. For now it is used to delete all user uploads when an account is purged. Later the list can be used for other purposes and made available through the API. > > ### Cursor based pagination > > 0.19 adds support for cursor based pagination on the /api/v3/post/list endpoint. This is more efficient for the database. Instead of a query parameter ?page=3, listing responses now include a field "next_page": "Pa46c" which needs to be passed as ?page_cursor=Pa46c. The existing pagination method is still supported for backwards compatibility, but will be removed in the next version. > > ### User data export/import > > Users can now export their data (community follows, blocklists, profile settings), and import it again on another instance. This can be used for account migrations and also as a form of backup. The export format is designed to remain unchanged for a long time. You can make regular exports, and if the instance becomes unavailable, register a new account and import the data. This way you can continue using Lemmy seamlessly. > > ### Time zone handling > > Lemmy didn't have any support for timezones, which led to bugs when federating with other platforms. This is now fixed by using UTC timezone for all timestamps. > > ### ARM64 Support > > Thanks to help from @raskyld and @kroese, there are now offical Lemmy releases for ARM64 available. > > ### Activity now includes voters > > - Previously, site and community activity counts were only based on people who commented, or posted. Those counts now include anyone who voted on a comment or post as well. Thanks to @Ategon for this change. > > ## Upgrade instructions > > Follow the upgrade instructions for ansible or docker. The upgrade should take less than 30 minutes. > > If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat. > > Pict-rs 0.5 is also close to releasing. The upgrade takes a while due to a database migration, so read the migration guide to speed it up. Note that Lemmy 0.19 still works perfectly with pict-rs 0.4. > > ## Thanks to everyone > > We'd like to thank our many contributors and users of Lemmy for coding, translating, testing, and helping find and fix bugs.

  • Welcome, to the new Mobilizon instance of tchncs

    events.tchncs.de Time to finally test Mobilizon

    Nov 6, 2023, 10:15:00 AM - GMT+1 - On popular demand... testing period will last until the end of January 2024 – within this timeframe, I need to figure out whether this software is solid for production and whether people (you) actually…

    Time to finally test Mobilizon

    Mobilizon is federated software in the same network as Lemmy (but with some intentional restrictions*), to help you organize your online or offline events!

    The instance is now slowly opening its doors. For now, logins are restricted to our accountsystem at auth.tchncs.de but this might relax once a few things have been figured out.

    At the end of january 2024, i might evaluate whether people are actually using that instance and if it makes sense to keep it online.

However, the checkbox does not stay in "done" state and the task goes back to the "incomplete" state. Also, I get a green popup on the bottom momentarily with the message:

  • Question about Fediverse login.

    Hello all!

    I was looking at tchncs.de and all it federated services offerings. I was wondering if, having a lemmy account here, I could log in to Mastodon and Pixelfed.

    When I tried just now, I couldn't. Is there a way to do this and I was too dumb to figure it out, or I need an account for each service?

    Thanks!

  • "Show context" for comment not working

    Am I the only one where the "Show context" button doesn't do anything, when I look at a reply to one of my comments?

    It works in Apps, but not when using the normal website.

  • Why is lemmygrad not a banned instance anymore?

    I remember when I joined here that tchncs did not federate with Lemmygrad. Is there a reason why it is now? I don't think it's a good instance, since it full of (roleplaying) communists hating on the western world... and I wouldn't want that shit in my "All" feed. Thank you.

  • Block a community system-wide

    Is it possible to block a community on system level? i.e. [email protected] is a massive nswf spam sink of hundreds kbin.social local accounts. Or should we rather remove/purge it entirely?

  • [Matrix] outgoing federation repaired

    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.

  • [Matrix server] Upcoming maintenance and backup restore July 31

    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 not forgotten that i wanted to update that database. It's just that i was busy debugging federation problems.
