Some of Heinz von Foerster's central topics of reflection (the crucial role of the observer, the admission of the autonomy of the knowing subject, the rejection of all absolute conceptions of truth, the significance of paradoxical and circular figures of thought, etc.) are of consequence to university education and teaching in many different ways.

The author crucially describes the central ideas of Heinz von Foerster and related authors on education, learning and teaching.

The author shows that the concepts developed by Heinz von Foerster suggest a paradigmatic re‐orientation; the concept of knowledge transfer must be replaced by the stimulation of self‐directed learning geared to the reality of students; learning environments must be created that enable students to recognise and experience ready‐made answers primarily as questions, and solutions primarily as problems. The constructivist understanding of the multiplicity of worlds and realities is particularly well suited for university teaching to support intellectual curiosity, fascination, and cooperative reflection.

Heinz von Foerster's brand of subversive constructivism inspires the dismantling of stifling hierarchies of knowledge, encourages dialogue‐oriented learning, relies on the autonomy and intellectual self‐sufficiency of the individual, and stimulates the delineation of ideal‐type role‐models and interaction patterns of different kinds.

Attention is drawn to an announcement of two publications relating to the work of Humberto Maturana, and to a new online encyclopedia of systems and cybernetics. The latter uses Wikimedia technology for free interaction, and this is discussed. Advice on combating spyware and other forms of malware is reviewed, as well as surveys of how to make computers quieter in operation, and of the worrying question of when to switch off between periods of use.

The aim is to review developments on the internet, especially those of general cybernetic interest.

Some of the developments reported have research value, while others bear on practical aspects of computer use and internet access.

The comments on security may prompt urgent action by readers. Otherwise the implications are for access to information and for computer quietness and economy.

It is hoped this is a valuable periodic review.
