Since this website went online nearly five years ago, the comment function has been abused to submit spam. Recently, the number of spam comments reached more than 1000 per day. There are only seven comment which are not spam. Therefore, it was decided to disable the comment function completely.

A few days ago, Google released their new Hangouts software which supersedes all chat systems previously being used by Google. Unfortunately, Hangouts does not support XMPP federation. That means that Hangouts users are not able to communicate with users on non-Google XMPP (Jabber) servers anymore.
In the recent days, jabber.rueckgr.at suffered from some stability issues (refer to the Statistics page for details). These problems should be fixed now. Kudos to Randy's Blog for providing a straight-forward solution to the problem.
Update: Unfortunately, the problems are not yet resolved. I'll keep you updated.
