Paul Schaub Application 2020

Jump to navigation Jump to search

My name is Paul Schaub, also known as vanitasvitae. This is my re-application as a member of the XSF.

About Me

I have a bachelors degree in computer science and currently I'm studying to get my masters degree. I'm also employed in a student job at my university hospital, doing medical informatics stuff, sadly no XMPP :( My involvement in XMPP began when I implemented OMEMO encryption for the Smack XMPP client library as part of my bachelors thesis. Since then I visited 4 XSF Summits and 2 Sprints, took part in two XMPP related Google Summer of Code projects and became the number 2 contributor of Smack.

My main interests are end-to-end encryption which is the reason why both my bachelors thesis was and my master thesis will be around that topic. Although I don't feel confident enough in my knowledge I'm the formal leader of the SIG-E2EE which focuses on advancing end-to-end encryption protocols within the XSF.

In my spare time I'm writing articles about XMPP and free software on my blog.

I'm also a (currently inactive) supporter of the Free Software Foundation Europe, as well as a member of the Federated Networks Association Feneas.


I believe that open standards, encryption, privacy and free software are essential building blocks for a healthy democracy. That's why I want to continue to support the XMPP Standards Foundation as a member to help creating a healthy communications ecosystem.
