Abstract: Techniques for device configuration of prospective contacts using messaging history information are described. In one embodiment, an apparatus may comprise a client front-end component operative to receive a client inbox request for a user account from a client device, the user account for a communication system; and send an ordered prospective contact list to the client device in response to the client inbox request; a prospective contact list component operative to generate a prospective contact list for a user account, wherein generating the prospective contact list for the user account excludes any existing contacts from an existing contact list for the user account; a predicted interest component operative to determine a predicted communication interest for each prospective contact on the prospective contact list; and a contact ranking component operative to determine a ranking weight for each prospective contact on the prospective contact list. Other embodiments are described and claimed.

Abstract: Exemplary embodiments relate to techniques for the atomic switching of user accounts for a messaging client, in order to maintain constant network availability of the messaging client. The messaging client may allow the registering of multiple messaging accounts and switching between them. Switching may include validating a selecting account, logging out the currently-active account if validation is successful, and logging in the selected account. If validation or logging-in fails, the messaging client remains logged-in to, or returns to, the previously-active account. A limited token may be maintained for inactive accounts and may allow for the retrieval of information such as whether inactive accounts have unread messages, and if so how many, without allowing further access. The messaging client may therefore periodically poll the messaging system (or vice versa) and display notifications for inactive accounts, and the inactive accounts may still be listed as available via the messaging system.

Abstract: A system and method for simultaneously coordinating a wake control system and a noise control system of a wind farm having a plurality of wind turbines is disclosed. The method includes determining, via a farm controller, one or more wake control set points for the wake control system.
