Jetzt wo ich meine durch die FOSDEM angestaute INBOX in Friendica auf 0 gearbeitet habe, steigt die Vorfreude auf die @Chemnitzer Linux-Tage am 22./23. März ungemein an 😀 Das wird so entspannt werden - entspannt und ungemein interessant.

Muss ich nur noch wieder wach werden xD

End of #FOSDEM 25 with @llas’s (impressive) keynote about @fsfe’s work to defend #SoftwareFredoom at the EU highest court. Kudos for the amazing work done until now by Lucas and @pjitendra and everyone else involved!

We want do defend the #DMA and continue to pave the way for #DeviceNeutrality. Please support the FSFE: your donation enables our work https://fsfe.org/donate

#Fediverse needs a lot of lobbying in public institutions (incl. Universities)

"We have a lot of solutions for problems which have not been identified as problems by many"

Just uploaded my slides from the FOSDEM talk also to my collection of talks at https://fsfe.org/tobiasd/talks so they are not only at the events website.

On my way from Vienna to Brussels to visit #Offdem and #Fosdem

It's my first time there!

I'm looking forward to meet people who are interested in:
#policy topics regarding the #Fediverse
#Commons
#Wikipedia

Please let me know if you are - so we can meet and talk.

Interesting experience... I have not done a Friendica only presentation for some time. During the recent years it was mostly introductions to the Fediverse or more topic orientated talks / workshops. First iteration of the slides for the Social Web Devroom at FOSDEM (Saturday 15:30 to 16h) is done 🚀

In der letzten Woche durften wir gemeinsam mit @heinleinsupport zu Gast sein auf der @fosdem in Brüssel! Wir danken allen Anwesenden, die unsere Vorträge besucht haben und mit uns in den Austausch gegangen sind!

Getting ready for #FOSDEM

On my train to Brussels via Colonge. Hope to see you at FOSDEM 😃

Easiest way to find me is likely at the booth of the Free Software Foundation Europe (Building K, level 2).

If you’re going to a talk at #FOSDEM by someone who is the sole maintainer of code you rely on, wear a mask! If you’re one of a small number of contributors to an open source project, wear a mask!

We talk about “bus numbers” but at an event without a public health pledge, your project should consider “COVID numbers”. Long COVID hits marathon runners, young people, vegetarians and meat eaters, people with the vaccines, etc.

Protect each other out there. #CovidIsNotOver

📣 Wir sind dabei: Tausende #OpenSource-Developer treffen sich am 3./4.02.24 auf der #FOSDEM in Brüssel.

Die Vorträge von Heinlein und OpenTalk:

👉 Heinlein-Consultants Carsten Rosenberg und Manu Zurmühl fragen, ob man eine effektive #Mail-Security-Infrastruktur mit Open-Source-Komponenten bauen kann.

👉 Entwickler Wolfgang Silbermayr gibt Einblicke in unser #OpenTalk-Projekt, die Service-Architektur und den Stand der Entwicklung unserer souveränen #Videokonferenz.
