For non-critical information, E-Mail works best. Reach me at r at rixx · de, and consider using my GPG key: 0xe1f56ce6693f9c45. I typically answer within a day or two at most, if I'm not on vacation.


My preferred messenger protocol is Jabber, where I can be reached at rixx@jabber.shackspace.de. I use IRC as rixx on freenode, hackint and some other networks. If I'm online, chances are I'm reading IRC or Jabber.

If it is really urgent, you can reach me on Threema as MXXPW35P. If it's even more urgent, you already have my phone number.

Social Media

I have a Mastodon account on my own instance, and apparently I've still got a Twitter account.
