In the nice setup of my own “un-clouded” PIM (personal information manager), in which DAViCal plays a major role, OS X Lion (10.7) & OS X Mountain Lion (10.8) seemingly can’t handle the groups in the address book (Contacts.app) any longer. – When connecting through CardDAV, the groups just remain empty.
In the respective paragraph 7.1.1 of RFC 6352, which Apple released in August 2011, states:


Description: The CARDDAV:addressbook-home-set property is meant to
allow users to easily find the address book collections owned by
the principal. Typically, users will group all the address book
collections that they own under a common collection. This
property specifies the URL of collections that are either address
book collections or ordinary collections that have child or
descendant address book collections owned by the principal.


… though Contacts.app sets the value of addressbook-home-set to /caldav.php/foobar/ instead of /caldav.php/foobar/addressbook/ in ~/Library/Application\ Support/AddressBook/Sources/XYZ-123456-FOOBAR/Configuration.plist, which is a violation of RFC 6352.

Simply said: OS X 10.7/10.8 Contacts.app cant handle its own technical specifications…

[Update: The very same bug has been reported to the sogo bugtracker.]

[Update: Here is a fix for this OS X bug.]

We come in peace

We come in peace, said the conquerers of the New World.
We come in peace, says the government, when it comes to colonise, regulate, and militarise the new digital world.
We come in peace, say the nation-state sized companies that have set out to monetise the net and chain the users to their shiny new devices.
We come in peace, we say as hackers, geeks and nerds, when we set out towards the real world and try to change it, because it has intruded into our natural habitat, the cyberspace. Let us explore each other’s truly peaceful intentions at this year’s Chaos Communication Congress 27C3 to be held from Monday December 27 to Thursday December 30, 2010 in Berlin, Germany.
