- 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 The review found that the topology used in the SLL’s network is still viable but WiMAX is now outdated.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.

- Description: The widespread adoption of blockchain technology has had a big impact on how people transact in the digital world. Individuals can transact in an anonymous but transparent manner. Their identities remain hidden but the records of their transactions are publicly available. This has had its benefits in certain application areas but might not be suited for transactions where it is important to know who you are dealing with and in circumstances where the data in the blockchain might be confidential. Private blockchain networks are better suited for such transactions as only authorized users can transact on the network. Sensitive data can also be stored on the blockchain as it is possible to restrict the users that can see the details of the transactions. This paper describes how to create a private blockchain network and how other users can join the network. It also details the benefits of using a private blockchain network with regards to data privacy as opposed to a public network.

- Description: Health is the biggest challenge to a majority of citizens regardless of age group and with the shortage of major components in the healthcare sector, life expectancy tends to reduce due to a lack of facilities. Technology on the other hand is reaching out to meet some of the demands that the healthcare will continuously require in order to deliver their services on time. One such technology is known as the internet of things (IoT). IoT has already proven its great potential towards the healthcare domain. IoT has the ability to allow patients to be monitored from the comfort of their homes through sensors equipped within devices deployed to perform specific tasks. The other technology is none other than the Blockchain which was introduced to deliver its capabilities in the financial ledger. The Blockchain helps to keep track of all the transactions being recorded, which in healthcare sector the need for Blockchain can be transformed to keep a trace of patient records. Since the IoT devices have the capability to monitor vital signs in the human body, it will be of a great achievement to integrate it with the Blockchain to keep an efficient system of healthcare records. The approach of this work is presented based on an Blockchained-IoT system to improve challenges of storing patients’ data captured by wearable IoT devices to help medical caregivers to make more informed decisions based on the efficient healthcare record-keeping. The design science approach will be proposed in our research to run the full experiment of our work.

- Description: Siyakhula Living Lab (SLL) in the Eastern Cape of South Africa, is interested in prototyping various software solutions to get non-commercial farmers to integrate into the agro-processing industry, particularly in the wool and fiber industry. The work reported in this paper proposes one of such software solution. It an initial implementation of a Radio Frequency Identifier (RFID)-based flock management system. The project started with a review of existing RFID solutions for livestock as well as RFID technology itself. Then it designed, built and performed initial testing of the prototype of an Android mobile application which is supported by a backend application server called TeleWeaver. The application will allow testing the hypothesis that ICTs can help non-commercial farmers better manage their livestock to improve the quantity and quality of wool products produced. The research has paved the way for future work in the field of RFIDs for livestock control in marginalized rural areas.
