FYI: Today about 220 inactive user accounts got deleted by the script. Many more received a notification mail...

From now on the script will run on every Thursday at 8:20 local time (CET/CEST).

The next run will warn users between 6 and 18 months inactivity and will delete all accounts with more than >18 months inactivity.

Ah, I see I need to change the mail text a little bit.. will do that for the next run in about a week...

I've activated a cleanup script that is checking your last login time.
If you haven't logged into for more than 6 months, you'll receive a mail.

Accounts that haven't logged in for 24 months will be deleted.

In the end the deletion will be lowered to 7 months so that you'll have 4 weeks to react to the weekly reminder mails.

Deleting unused accounts is a matter of digital hygiene and data protection.

There are some security updates necessary. This will require a restart of the server.
Hopefully this will take about 15 mins for reboot when initiated...

There was a small outage today (16:51 to approx 18:30 CEST). The server just hung and needed some extra love.
Luckily this doesn't happen that often, but very rarely. This was the first hanging server in the past 4 years or so...
So cross your fingers for the next 4 years... :-)

I've imported a set of custom emojis... somewhat nerdculture related emojis, like :debian: :firefox: or :xmpp: and many others. You can use those emojis in your profile display name as well.

Sadly, several SSL certificates did expire this night. This is already fixed and service should be back to normal. Sorry for the inconvenience!

Technical note:
For test purpose I disabled all domains in letsencrypts domains.txt file except a few. You can guess what happened... ;-)

There will be a short downtime to reboot the server for a security update.

Frohes neues Jahr!
Happy New Year!
Buon Anno!

May the year 2021 be better than the last one. Especially a quick end to the pandemic and healthiness to everyone of you!


As a late Xmas gift, Mastodon v3.3.0 has been released today and Nerdculture has been already updated to that release.

Read the release notes for more information what's new & shiny...

Upgraded lately to v3.2.2 and also set up Elasticsearch, so you should hopefully get better search results.
Also tried to speed up things a little bit by adding more CPU/threads to Mastodon...

Reboot finished, service should be back to normal...

There will be a maintenance downtime soon to restart the server, because a security update is pending.

Stay tuned and retry later if service is temporarily unavailable...

Dear Nerdculture users,

in this week I will work on the undelying network setup of this server. This means that Nerdculture will be unavailable during that maintenance work.
The downtime might happen multiple times in this week, but I'll try to keep it below 1 hour per period.

When done, I'll inform you again. Stay tuned!
