Nerdica upgraded to 2020.03 release

!Nerdica Forum

I've just upgraded Nerdica to the latest Friendica release 2020.03.

You can read in the release notes what's hot & new:

Christian mastodon (AP)

which app currently works best with # Nerdica on Android?
Server: @nerdicasupport

For your information: I have activated 2FA.
Basically, no idea... I'm on iPhone, so can't comment for Android based on own experience. Some people seem to like Fedilab, I think. Maybe ! is more helpful...
I am have nerdica and using Fedilab. However, 500 max characters per post though.

Nerdica upgraded to 2020.03 RC1

!Nerdica Forum

Sorry for the downtime, but upgrading to release candidate 2020.03 RC1 of Friendica took really long due to very long lasting database update.

See for details what changed.

Please report any issues you encounter to !!

Registration and Number of Active Users

!Nerdica Forum

Currently Nerdica has about 1520 users. The website reports for Nerdica.Net:
Users: 681
Last 6 months active users: 409
Last month active users: 215

So, with that numbers you can relate things a little better... We have like 2.5x the user count that the-federation is reporting. Applying the same rate to the "Last month active users" count would make it like 500 active users, but likely the number is lower.

My goal for this year is to...
1) increase the number of active users
2) decrease the number of dead/inactive accounts

In the end I would be below 1000 users, but like >800 active users. Inactive users are of no benefit for the #.

For that to happen I'll reduce the number of maximum users over time from now 1600 down to 1000 and remove inactive users that didn't post anything or were logged in the last 12-6 months.

I'll also announce this to all users the other day, so that everyone will get notified and is aware to either login regularly or delete his account if the account is no longer used.

Thanks for your understanding!

Reorganizing server storage

!Nerdica Forum

In the next hours/days I want to reorganize the storage. This involves copying tons of stuff around, which might slow down the service a little bit, and even some sudden outages, which only should be some minutes each time.

No big deal in the end, but well....
Ok, maintenance is basically done.
There is still a background task going on to copy some storage content for Friendica to a new location. This may or may not have to do with a display problem right now with avatars and other media files...
I hope that this will solve by itself in the next days. Anyway, I will have a look at this and try to get some feedback from the developers...

Nerdica upgraded to 2019.12

!Nerdica Forum

Merry X-mas! has just been upgraded to the newest release 2019.12.

Here's a snippet from the release notes:
The titles of all the pull requests of the 2019.12 release summarized as word cloud.

The ACL dialogue introduced in the 2019.09 release on the new compose page for the frio theme was now adopted to all themes.
The handling of reshares was made more native for the federated platforms and federation with Diaspora*, Mastodon, Pixelfed and Peertube was improved.
The API was improved and got some new endpoints to improve the experience of using Friendica with mobile apps like Fedilab.
Postings can now be pinned to your profile wall and
if you like, you can connect to Discourse forums via email.

Please report any issue you experience to the Friendica support forum at !, so that issues can be fixed soon.

Otherwise: Enjoy the fediverse! :-)

Public api endpoint to get public information about an instance?

!Friendica Support !Nerdica Forum
Hello everyone,
I am currently researching the fediverse as part of my bachelor thesis and I would like to briefly ask you if there is the possibility to get some information about an instance with an api call that does not require authentication.
Since I am trying to build a graph that depicts the various interconnections between Friendica instances, what I need the most is the list of instances that one particular instance follows, and the user count (just to have an idea how big an instance is). I do not need and do not want any kind of personal data. Exclusively metadata of public instances to analyze.
The only open api call I found is /api/statusnet/config but it does not contain enough information.
Any kind of help would be extremely appreciated.

Connect mastodon to nerdica

Hi @el_chava how can I do to post on mastodon and that the post appears on nerdica? also @Nerdica Forum @Ingo Jürgensmann
Ingo Jürgensmann friendica (via ActivityPub)
Well, have a look at remote_self in and lookup for the Atom feed in Mastodon of your user.

I've managed to setup my Mastodon/Friendica accounts that way as well.
Agustin Haro friendica (via ActivityPub)
Thank you very much Ingo!

Hi everyone! Could someone please explain how to create such a group as promoted on the #Friendica website? !Friendica Support !Nerdica Forum
Ok great, and can Friendica forums be private and invite-only?
Awesome, that's what I needed, thanks.

Maintenance window

!Nerdica Forum

There will be a short server outage starting at 13:00 CET to apply some security updates.

Nerdica upgraded to 2019.09

!Nerdica Forum

Today, approx. between 11 and 12:00 CEST, the Nerdica was offline, because I upgraded to newest release version 2019.09 of Friendica and well, not everything went well, but now it is running on newest stable release.

Have fun!

Twitter Plugin?

!Nerdica Forum

Another topic:

Do you mind when I disable the Twitter plugin? Do other people use it here?

I mean: you are using Friendica or the Fediverse in whole by purpose, because you decided to not use Twitter. I don't think that anyone is using Friendica as a Twitter client.

So, are we ok with disabling the Twitter plugin on Nerdica?
Ok, I've now disabled the Twitter addon.

Limiting number of users - now in place

!Nerdica Forum


As already proposed some weeks ago, I've now implemented a method to shutdown the open registration when there are 1200 users on Nerdica. Currently we are at 1194 users.

Registration will automatically re-open when the number of users drops again under 1100 users.

Already registered users can invite family and friends to Nerdica.Net regardless of public registration status being open or closed. Just invite them by mail.
But public registration will now be automatically closed and re-opened as described.

Short interruption

!Nerdica Forum

There was another short outage for maintenance to mitigate some CPU bugs:

SUMMARY: CVE-2017-5753:OK CVE-2017-5715:OK CVE-2017-5754:OK CVE-2018-3640:OK CVE-2018-3639:OK CVE-2018-3615:OK CVE-2018-3620:OK CVE-2018-3646:OK CVE-2018-12126:OK CVE-2018-12130:OK CVE-2018-12127:OK CVE-2019-11091:OK

Services should be back to normal now.

Is it possible on github to post an issue potentially affecting two seperate projects at once? Because I would like to post this issue ( ) potentially affecting the two projects (cc @nerdicasupport ) and # (cc @fedilab ) simulataneously.

A warning for #- and #-users: unfortunately there currently is a giant security-issue if you try to use Fedilab with a If you are doing this you will always be logged in to someone elses account instead of your own and there is also another problem: unlike f.e. also doesn't ask to authorize the Fedilab-app. It just redirects you to the account the Fedilab-app logged you in to.

cc @nerdicasupport @fedilab
Ingo Jürgensmann friendica (via ActivityPub)
So to give an update from a different discussion:
Fedilab apparently shows (a more or less random) user profile when the account credentials don't work and displays public posts.
No issue in regard of security, as it seems.
Fedilab mastodon (AP)
Not a security issue I confirm. I checked it deeply. As soon as it requires a token, it throws a 401.
But, the reply for the random account comes from the server reply.

Limiting number of users?

Ingo Jürgensmann friendica (via ActivityPub)
Limiting the number of registrations or users on Nerdica doesn't mean that the number of users for Friendica is limited.
Currently we have about 100 Friendica nodes listed, but most users are registering on the big 4 nodes. This makes it difficult for smaller nodes to grow. And therefor closing down registrations when a high-water mark is reached can improve the situation (=user count) for the smaller nodes. And there can help with the robustness of the Fediverse in general: more nodes of the same size instead just a few bigger nodes.

Your comment is very much appreciated! :-)

Nerdica upgraded to 2019.06-rc

!Nerdica Forum


Just some minutes ago I upgraded Nerdica to current release candidate version 2019.06-rc:

Friendica 'Dalmatian Bellflower' 2019.06-rc - 1313

Prior upgrade tries were failing, but this time everything went well.

If you experience any issues please report them to ! - that way the issues can be worked on directly by the developers.

Downtime on Friday

!Nerdica Forum

Dear users,

as you certainly have experienced on Friday, Nerdica.Net was unavailable for a longer time.

What happened?

Well, I tried to upgrade the underlying Debian Linux installtion from stretch to buster. Although I did that before on other virtual servers, there was a new problem on this server: the Apache webserver didn't want to start.

Unfortunately, as a bonus challenge, I needed to go away from my desk and was only able to work on the issue via my iPhone SE and an SSL client. This lead to longer time to fix this issue than it would have been when I was still on my laptop.

In the end everything should work again. If you experience some problems, please drop me a note. Thanks!

Failed upgrade to RC candidate

!Nerdica Forum

Dear users,

you may have experienced some outage this evening. Reason was that I tried to upgrade to the release candidate of Friendica 2019.06-rc today. This failed and I needed to restore the code from backup.

Apparently it is now running again on latest stable release.

Sorry for the inconvenience...
Ingo Jürgensmann friendica (via ActivityPub)
Today I tried again to switch to 2019.06-rc and it failed again the same way.

I won't give it another try until a new RC2 has been released or the final release version is available.


Nerdica upgraded to 2019.03-rc

!Nerdica Forum

Dear users,

this evening I switched Nerdica to the current release candidate 2019.03-rc of Friendica.

The migration took a little longer as the database upgrade failed again and again with a strange error. It took a while until I figured out was the problem was and fixing it.

Sorry for the unexpected long downtime, but now it should be running just fine again. If you experience any issues, please report here or in the Friendica Support Forum, where the developers are also reading...


Cross-posting to Wordpress from Nerdica

Hi -- I'm brand new here, and one of the things I wanted to be able to do from Nerdica/ was crosspost to my (self-hosted) Wordpress blog.

I found the Social Networks page, and the Wordpress Export section. But I can't find any documentation anywhere that explains what's being looked for in the key "WordPress API URL" field. Anyone have an answer, or know where I can dig up more information on this?

With API URL the addon means XMRPC API URL. There is also a REST API URL for Wordpress.
From the Wordpress addon system setting:
Post to WordPress (or anything else which uses blogger XMLRPC API)

Maybe this helps:
three_star_dave friendica (via ActivityPub)
So it looks like it's the path to the WP xmlrpc.php file ... hmmm, okay, thought I had that identified. That gives me something to play with. I'll give it a try and update this if I get it working. :-)

Thanks, Ingo!

Can't connect to with XMPP-client

I just tried to connect to my account on with but got the error message "Incompatible server"? should be a real XMPP client? The information about also says:

"All (friendly) creatures welcome! Free registration. Server located in Germany. As a registered user on Nerdica.Net you are also able to use XMPP (Jabber) under the same address and with your password. Get the best of free and open networks at Nerdica.Net! :-)"
After help from @Ingo Jürgensmann I think we can be pretty sure the problem is in the client in connection with the nerdica server. When I try to connect with another client, Xabber for Android, it works fine.
Ok, I checked back with Daniel Gultsch on Twitter... in his opinion the problem might be that I'm using "slt" for proxying SSL connections to TLS and TLS is expecting STARTTLS command... So, the compliance tester is happy with the current setup, but the real client is not.

For some unknown reasons (at the moment) the configuration does not work as documented (legacy_ssl_ports for Prosody)...

Workaround for bug in newest release applied

!Nerdica Forum

There is a small nasty bug in newest Friendica release 2019.01:

When enabling "use browser location" the modal for writing the post doesn't appear

So, when you're using browser location you might not be able to post anything on Nerdica.Net. As a workaround I've followed the tip to disable this function on SQL level:

MariaDB [friendica]> UPDATE user SET `allow_location` = 0 WHERE `allow_location` = 1;
Query OK, 10 rows affected (0.01 sec)
Rows matched: 10  Changed: 10  Warnings: 0

As you can see there were 10 users affected. In the development branch this bug has already been fixed, but I still await a fixed release version. As soon as this fix is available you should be able to enable "use browser location" again.

XMPP for all Nerdica.Net Users

Oh, sorry... thought that the default setting will be used as a default in the user settings as well. You'll need to set the BOSH URL to:

Hope, this helps. Otherwise you can also use the fully featured webclient on - there you'll need just your account and password.
Ok, I see you in the chatroom and also have added the BOSH URL to the original posting...

Nerdica.Net upgraded to 2019.01 release

Upcoming Server Works

!Nerdica Forum

Today I sent a Samsung NVME M.2 disk to the hoster in order to have that put into the server and to speed up the underlying database of Friendica on Nerdica.Net.

This is somewhat strange... Although I bought that server, I've never seen it personally. It was directly sent to the colocation hoster and now I'm somewhat curious whether or not everything fits into the box.

So, expect some downtimes of the server in the next 1-2 weeks. Until everything is settled and tuned, it will need some reboots and such.

Maybe some interesting facts for the techies of you:
- database size: 19 GB at the moment
- mem/pool size: 16 GB
- current disk setup: 4x SATA disk RAID10
- 6x Xeon cores
It's somewhat likely that the SSD will be put into place around December 12th, so in about 3 weeks. The hoster will then be at colocation space for another costumer and I won't need to pay an additional fee for installation. :-)
The downtime has now been scheduled for Thursday, Dec. 13th, between 18-20:00 CET. The colocation provider will then shutdown the server and install the SSD. After that I need to make some tests and move the databases from the RAID10 to the SSD.
This will take some time, but I guess the server should be back up again at 21:00 CET...

Friendica and GDPR

Although I think JPA did a great job in the legal process of GDPR, but what came out is a little too bureaucratic and over the top for private users.
It's quite unlikely that I will conduct such a "paper".
That's why I said that I will shutdown everything on that moment when I'm forced to do so. This will also be the case when upload filters are required by EU legislation. That wouldn't be a free and open Internet anymore, because already today you need a master degree at a law school when running some services on the Internet.
I totally agree with you on the amount of formality and bureaucracy that is required. I don't have a law degree either and sometimes I have no choice but to ask for the assistance of a lawyer. And I definitely didn't want to make you upset. ;)

But if I had a saying in this I would rather make friendica my "safe social networks harbour" which requires the administration to meet legal requirements rather than to have yours, mine and everyboby elses endeavors shatter at the first sign of trouble. Running an internet service that deals massively with personal data is not something to treat lightly. But I also think it is possible to tackle all requirements. At least it is worth a try.

Since of today is secured by DNSSEC. There shouldn't be any issues because of this. Just to let you know... :)

help for configuring an app

hi everybody :)

i am a sailfish os users and wanted to try out Friendly, the native app. Thing is i cannot configure the app, maybe someone can give me some hint? :)

Nerdica.Net upgraded to Friendica 2018.8-RC

!Nerdica Forum

After the message came in today that Friendica 2018-8rc1 has been released I upgraded Nerdica to that version. The database conversion took a while, but in general there was no problem during upgrade.
Only thing that seems a little bit odd is the rendering of Umlauts, which seem to be broken, but I guess that this issue can be solved shortly. So, stay tuned! :-)

Admin Nerdica.Net
That makes sense. Never mind!
Yeah, nonetheless I checked the app permission list in Twitter and it is still activated - alas apparently not working anymore.
That's one of the reasons why so many users are moving away from Twitter into the Fediverse lately...

Ah, you maybe want to try IFFFT or Buffer addon instead... But this also means to invoke another third party into your communication channels and giving them access to your stuff...
*narf* ... couldn't await the day to completely ditch twitter. ;-)


!Nerdica Forum
Hi, ich bin neulich mit diesem Account von Libranet hierher umgezogen. Der Umzug hat auch ganz gut funktioniert. Mit einer Ausnahme, die vielleicht auf einem Missverständnis beruht, dass ihr vielleicht aufklären könntet. Und zwar lässt sich der Nerdica-Account nicht mit anderen Instanzen föderieren, die zuvor schon den libranet-Account kannten. Und dabei geht es nur um den Libranet-Account (nicht um die ganze Instanz!).

Warum ist das so?

Vielen Dank für jede Antwort!
Ich vermute gerade, dass es so eine Art Alias-Mechanismus gibt, den ich jetzt unterbrochen habe. :-(
Ja, kann gut sein, aber da wissen vielleicht @Michael Vogel oder @Tobias weiter...

Picture upload issues

Anyone know why i am getting a regular upload fail for pictures? It seems i can upload small files only. Is there a file size limit?

As stated before, there might be a 2 MB upload limit, although I lately changed all the occurances in php.ini and raising it to 20 MB.

Formatting Text


Does Friendica allow formatting of text in posts? Am I to use HTML or Markup to do that? Is there some sort of WYSIWYG (What You See Is What You Get) interface for posting?
I think you can use BBcode to format text.

Welcome to all new users

!Nerdica Forum

To all of our new users a friendly welcome!

There are lots of new users in the last days apparently coming from that #deletefacebook campaign.
Maybe you are wondering why there is no traffic in your timeline after joining. #Friendica is working a little different than Facebook and you actively need to search for your contacts to connect to. There is no automatism finding your friends via uploaded phonebooks or similar. This is by design for the sake of privacy and data protection.

So, please don't be disappointed when your timeline seems to be empty in the first days. Start posting stuff, experiment with your profile settings who can see what and connect with other users in the Fediverse.

Have fun!
Is there a link to the community page?

Ingo Jürgensmann friendica (via ActivityPub)
Welcome to Nerdica!

Maybe you should address these question to the Friendica Support forum? There are the more protocol-knowing developers, but I'd assume that both issues might be caused by some differences in protocols or software like Friendica vs Hubzilla/Mastodon/Diaspora.
So, when e.g. Mastodon doesn't know the concept of privacy groups, it might be not possible to answer to those articles. But again: the developers in the ! might know more details...

XMPP addon activated

!Nerdica Forum

I've activated the XMPP addon on Nerdica.Net. In your user settings you can activate this addon. Basically it should be pre-configured with the correct BOSH server settings.

If you want to use it, you need to have an existing XMPP account. If you want to have a user account on Nerdica.Net, please contact me. I'll give out XMPP accounts under Nerdica.Net domain and can even provide you with a matching mail address. That way you will have the same contact address for your Friendica account, XMPP address and your mail address. Only requirement is that you are an active user on Nerdica.Net for some time.

Have fun!
