“…The components are encapsulated in heavy‐weight virtual machines. Microservices: The University of California Curation Center presented an open‐source micro‐services infrastructure 57 that is being used to manage the diverse digital collections of different University campuses. The basis for this microservices 62,63 approach is Unix pipelines, 64 which gave rise to the software architecture of computing pipelines. This proposal is based on a centralized system, where each microservice includes the accessible web addresses of other services that it requires for its operation, the communication between them is carried out through RESTful requests.…”

This article presents the design and implementation of a reliable computing virtual container‐based model with integrity verification for data processing strategies named the reliability and integrity verification (RIV) scheme. It has been integrated into a system construction model as well as existing workflow engines (e.g., Kulla and Makeflow) for composing in‐memory systems. In the RIV scheme, the reliability (R) component is in charge of providing an implicit fault tolerance mechanism for the processes of data acquisition and storage that take place in a data processing system. The integrity verification (IV) component is in charge of ensuring that data transmitted/received between two processing stages are correct and are not modified during the transmission process. To show the feasibility of using the RIV scheme, real‐world applications were created by using different distributed and parallel systems to solve use cases of satellite and medical imagery processing. This evaluation revealed encouraging results as some solutions that assumed the cost (overhead) of using the RIV scheme, for example, Kulla (the Kulla‐RIV solution), achieve better response times than others without the RIV scheme (e.g., Makeflow) that remain exposed to the risks caused by to the lack of RIV strategies.

“…To allow for correction, each sensor node attaches a timestamp to every data frame as soon as it is collected from the X4 radar. The timestamps have ∼1 ms precision and are all referenced to the UNIX time epoch [11] using the system clock set over the network using NTP. On receipt of a data frame from a node the supervisor software attempts to place the frame in the correct 100 ms time epoch.…”

This paper describes Tiresias, a low-cost, unobtrusive networked radar system designed to monitor vulnerable patients in domestic environments and provide high quality behavioural and health data. Dementia is a disease that affects millions worldwide and progressively degrades an individual's ability to care for themselves. Eventually most people living with dementia will need to reside in assisted living facilities as they become unable to care for themselves. Understanding the effects dementia has on ability to self-care and extending the length of time people living with dementia can remain living independently are key goals of dementia research and care. The networked radar system proposed in this paper is designed to provide high quality behavioural and health data from domestic environments. This is achieved using multiple radar sensors networked together with their data outputs integrated and processed to produce high confidence measures of position and movement. It is hoped the data produced by this system will both provide insights into how dementia progresses, and also help monitor vulnerable individuals in their own homes, allowing them to remain independent longer than would otherwise be possible.Radar, UWB, indoor tracking, networked sensing, longterm monitoring, dementia, integrated care. I. INTRODUCTIONDementia progressively reduces the ability of those affected by it to live independently. Affecting around 50 million people worldwide [1], the effects of dementia place a heavy toll on healthcare systems and remains a leading cause of patients requiring residence in assisted living facilities. Long-term monitoring of the behaviour and well-being of patients with dementia can allow clinicians to assess both disease progression, and the effects of any interventions or changes in circumstance.High quality behavioural data can be generated by monitoring patients with video cameras using computer vision or manual behavioural labelling. However, this approach is extremely obtrusive, comes with many privacy concerns, and would be very unlikely to be acceptable to many people living with dementia [2], [3]. On the other end of the obtrusiveness scale are sensor systems for individual actions, such as use of appliances, opening of doors and windows, or presence in a [4]. Unfortunately, with the unobtrusiveness of these systems comes a reduction in the quality of the data

“…To avoid this problem during software development process, developers commonly use a Source Code Control System (SCCS). While the idea and implementation of a source code management have been around ever since the early years of software development [1]- [2], the term SCCS itself was coined in a paper Marc J. Rochkind [3]. The main purpose of this system is to help developers to manage their source code.…”

Source code management is one of the most vital tools in modern software development. Moreover, the open source initiative requires a method to distribute their code effectively. GitHub is one of the most popular web-based version control systems that offers version control and source code management. Therefore, it is important to introduce GitHub as early as possible to computer science students. Our objective is to observe the use of GitHub as a source code management system. We perform a survey targeted at the students and collected 298 answers. We also perform a short interview amongst the lecturer regarding their familiarity with GitHub and source control management in general. The survey result shows that while GitHub is quite popular amongst the student, the knowledge and experience of using it is considerably low. Similar responses were received from the lecturer that argues that the role of GitHub in classroom is redundant. The details of the result are thoroughly discussed in this paper
