Tradi tional distributed computing is dominated by a client–server model. File systems, databases, and hypertext systems are all designed with the assumption that a few powerful and reliable servers support a large and dynamic set of clients. Servers are complex and expensive, while clients are lightweight, cheap, and simple. Servers are responsible for persistence, security, and coherence, whi...

where we can collapse values of x to the range 0 ≤ x ≤ 1, is sufficiently simple that much is known rigorously [1], yet displays the interplay between frequency locking and the onset of chaos from quasiperiodic motion. There are also a number of excellent reviews e.g. references [2] and [3]. The map is monotonic and invertible for K < 1, but develops an inflection point at x = 0 for K = 1 and t...

Gay communities in the developed world have rapidly achieved a remarkable level of behaviour change in facing the epidemics they have weathered. What might we learn from the example of the Australian gay communities that might be useful for other communities and popu...
