- Description: Changes within ICT over the past decade required a review of the network solution deployed in the Siyakhula Living Lab (SLL), a joint venture between the Universities of Fort Hare and Rhodes, focused on finding blueprints for sustainable e-infrastructure in poor communities. The review found that the topology used in the SLL’s network is still viable but WiMAX is now outdated. Also, the in-network cache, Squid, is no longer effective, given the switch to HTTPS, the strong presence of advertising, and the data weight of current web pages. The solution to the first issue is outdoor Wi-Fi, a proven solution easily deployable in grass-roots fashion. The second issue can be cured leveraging Squid’s ‘bumping’ and splicing features; deploying a browser extension to make picture download optional; and using Pi-hole, a DNS sinkhole. Hopefully, the revised solution could become a component of South African Government’s broadband plan, “SA Connect”.

- Description: This paper reports on the work done in the Siyakhula Living Lab (SLL) schools, a joint project between the Universities of Rhodes and Fort Hare. The computing infrastructure in SLL is based on the Linux Terminal Server Project (LTSP), which allows client computers to boot from a centralised server and in some cases offload the computation to the server. Most SLL educators find it difficult to manage classroom applications using the GNU/Linux tools directly. So, educators had to rely on others to add applications for their classroom activity, reducing their sense of being in control and making processes longer and less flexible. A recent development in LTSP has introduced the possibility of setting the boot image for the clients within a virtual machine. This paper explores this option in detail and proposes that educators switch to a virtualisation player to manage applications they want to use in the classroom.
