There have been many implementations of remote interactive servers for game playing in some universities or companies providing collaborative access to the remote services. Most current systems that provide a collaborative remote game environment either use the (multi) Unicast technique or the Multicast technique to transmit data packets to the participants of the experiment group in the network. Both of these schemes have disadvantages and advantages. In this paper we implement architecture under Linux for real-time multiplayer game application based on XCAST especially for the cases where there exist numerous small collaborative groups. We had provided extension to the Linux kernel and XCAST and show that formation of numerous simultaneous groups, where each group would collaborate for a separate game, is possible. The system proposed is robust in consistently providing group formation and collaboration activities in real time, back-up route or priority queuing, and on time packet delivery with minimum delay in network in the presence of continuous node arrival and departure in the entire game playing procedure. We also show that for data packets of low size, the use of XCAST in the network layer decreases the stress at the sender in each group whereas due to the increased header size of the XCAST packets. Our implementation has shown significant improvements to meet the demands of some real-time game applications.""

Politically Incorrect Observations About Human Nature 613

gsa writes "Why do men prefer blonds? Why are most suicide bombers Muslim? Psychology Today analyzes some of these non-politically-correct questions in this essay about ten politically-incorrect truths about human nature. It turns out there may be an evolutionary or psychological explanation for all of these observations. For example, 'Sociologists and demographers have discovered that couples who have at least one son face significantly less risk of divorce than couples who have only daughters. Why is this? ... There is relatively little that a father (or mother) can do to keep a daughter youthful or make her more physically attractive. The continued presence of (and investment by) the father is therefore important for the son, but not as crucial for the daughter. The presence of sons thus deters divorce and departure of the father from the family more than the presence of daughters, and this effect tends to be stronger among wealthy families.'"
