- Description: Motor vehicle ride sharing is a popular way of travelling in most coun-tries. Different incentives have made this mode of travelling to exist formally and informally, for example as in carpooling clubs and hitchhik-ing respectively. Advances in Information and Communication Tech-nology (ICT) have facilitated developments of formal Dynamic Ride Sharing (DRS) systems that target mobile devices. These are seen as solutions to people’s preference of flexible ride sharing services. In de-veloping countries, hitchhiking is a common technique for ride sharing travels. This paper describes a proposal to develop a DRS system that primarily targets mobile phone users in South Africa for informal ride sharing methods done in hitchhiking.

- Description: The councillor promised her ward an end to the humiliation of the buck-et system and the building of suitable sanitation facilities. It's why she voted for him. And while it has taken four years, today the building ma-terial for 40 toilets, one of which will be hers, has arrived. Of course, Eunice cannot be certain all 40 toilets will be built to the planned speci-fications and timeline; that's why she's monitoring the municipality's service delivery. Eunice has her phone ready and is counting the bricks and bags of cement that will become toilets for her street under her watchful eye and with the help of a mobile application, MobiSAM, and a local newspaper.

- Description: Underdevelopment and poverty represent key challenges faced by the modern world, which have attracted the attention of NGOs, civil society, government and multinationals. Various undertakings including the United Nations Millennium Development Goals articulation and the World Summit on Information Society highlight the global commitment towards addressing these problems. The solutions to these problems should be derived out of well-structured innovation systems that take into consideration the grassroot context and concerns. A number of in-novation models have been formulated and utilized effectively in differ-ent industries, and some of these have equally been used effectively in community development contexts. This paper elaborates on the Living Lab methodology and its application in ICT4D contexts, highlighting the effectiveness of this model towards integrating end-users within their problem solving effort. This is discussed through the backdrop of the Siyakhula Living Lab, an ICT4D intervention. The embedding environ-ment for this model, which enables key synergies with other stakehold-ers, is also discussed.

- Description: There has been much attention recently on the use of virtual class-rooms to support distance learning. However, the required real-time and high-rate transfers for multimedia contents such as video and audio that comprise most off-the-shelf virtual classrooms make them infeasible for developing countries where bandwidth is typically more restricted. This paper describes the findings of an ongoing investigation to develop a low bandwidth virtual classroom that can provide the necessary func-tionality to deliver courses to distant students. By combining Google Docs and Skype, we realised a low bandwidth virtual classroom alterna-tive that could provide adequate functionality within our teaching con-text.

- Description: Maillogs contain important information about mail which has been sent or received. This information can be used for statistical purposes, to help prevent viruses or to help prevent SPAM. In order to satisfy regula-tions and follow good security practices, maillogs need to be monitored and archived. Since there is a large quantity of data, some form of data reduction is necessary. Data compression programs such as gzip and bzip2 are commonly used to reduce the quantity of data. Text preprocessing can be used to aid the compression of English text files. This paper evaluates whether text preprocessing, particularly word replacement, can be used to improve the compression of maillogs. It presents an algorithm for constructing a dictionary for word replacement and provides the results of experiments conducted using the ppmd, gzip, bzip2 and 7zip programs. These tests show that text prepro-cessing improves data compression on maillogs. Improvements of up to 56 percent in compression time and up to 32 percent in compression ratio are achieved. It also shows that a dictionary may be generated and used on other maillogs to yield reductions within half a percent of the results achieved for the maillog used to generate the dictionary.
