Description: Intrusion Detection is essential in modern networking. However, with the increas-ing load on modern networks, the resource requirements of NIDS are significant. This paper explores and compares the requirements of Snort and Bro, and finds that Snort is more efficient at processing network traffic than Bro. It also finds that both systems are capable of analysing current network loads on commodity hardware, but may be unable to do so for higher bandwidth networks. This is ben-eficial in a South African context due to the increasing international bandwidth that will come online with the launch of the SEACOM Cable, and local projects such as SANREN.

Hold the prawns

Description: [From introduction]: In the cities of the global South elites are often desperate to repress the reality of the shack settlement. Maps are printed in which shack settlements appear as blank spaces, laws are passed that assume that everyone can afford to live formally and, in the name of order and development, the poor are beaten out of the cities. The great elite fantasy is the creation of 'world class cities' – shiny, securitised nowherevilles in which the poor understand that their place is to live in some peripheral ghetto and only come into the city as menial workers. But from City of God to Slum Dog Millionaire and now District 9 cinema has put the shack settlement in the mall and at the heart of how Rio, Bombay and Johannesburg feature in the global imagination.

Is HIV/AIDS jeopardizing biodiversity?

Description: The scourge of HIV/AIDS (human immunodeficiency virus/acquired immune deficiency syndrome) is most prevalent in southern Africa. South Africa has the highest number of people in the world living with HIV/AIDS and a prevalence rate of over 30 % for females presenting at antenatal clinics. There are now almost five million orphans within southern Africa, as a result of AIDS deaths of one or more or their parents. AIDS-related mortality and morbidity of care-givers may lead to increased reliance on wild sources of animal protein by surviving children. This increase in hunting pressure has unknown, but potentially important impacts on local animal populations.

Description: Eleven polymorphic microsatellite loci were developed from an enrichment library of the roman, Chrysoblephus laticeps, and characterized for 40 individuals collected in Africa's largest and oldest Marine Protected Area (MPA), the Tsitsikamma National Park. The number of alleles per locus ranged from three to 19, and heterozygosities ranged from 0.20 to 0.85. A significant departure from Hardy–Weinberg equilibrium was detected for one locus, and linkage disequilibrium was identified among three pairs of loci. The markers will be useful to detect whether populations resident in MPAs along the South African coast are genetically connected, and whether there is spillover of recruits into adjacent exploited areas.
