Adoption-Ready Project-Based Learning for Computing Education: The FORAP Framework and a Multi-Scale Project Portfolio

This innovative practice full paper presents FORAP (Framework for Organizing Reusable and Adaptable PjBL Projects) and a portfolio of 14 adoption-ready project-based learning (PjBL) project packages built with the framework. PjBL in computing education offers strong educational benefits, yet its adoption remains limited by high instructor workload and recurring student technical challenges. FORAP addresses these barriers by organizing each package around a project designed with aligned learning objectives and described through project attributes, along with coordinated instructor, student, and assessment materials that support adoption and adaptation across diverse computing courses. We report on four years of deployment across 44 classroom trials at seven universities, drawing on feedback from students, instructors, and advisory board members. Results suggest that structured project packaging supports feasible adoption with limited modification effort and that targeted support materials help reduce the technical barriers that commonly hinder student engagement. The contributions of this work include FORAP and a multi-scale portfolio that demonstrates its use across diverse computing domains and project scopes, offering practical guidance for instructors who wish to design, adopt, or adapt reusable PjBL projects in computing education.

Edge System Design Using Containers and Unikernels for IoT Applications

Edge computing is emerging as a key enabler of low-latency, high-efficiency processing for the Internet of Things (IoT) and other real-time applications. To support these demands, containerization has gained traction in edge computing due to its lightweight virtualization and efficient resource management. However, there is currently no established framework to leverage both containers and unikernels on edge devices for optimized IoT deployments. This paper proposes a hybrid edge system design that leverages container and unikernel technologies to optimize resource utilization based on application complexity. Containers are employed for resource-intensive applications, e.g., computer vision, providing faster processing, flexibility, and ease of deployment. In contrast, unikernels are used for lightweight applications, offering enhanced resource performance with minimal overhead. Our system design also incorporates container orchestration to efficiently manage multiple instances across the edge efficiently, ensuring scalability and reliability. We demonstrate our hybrid approach's performance and efficiency advantages through real-world computer vision and data science applications on ARM-powered edge device. Our results demonstrate that this hybrid approach improves resource utilization and reduces latency compared to traditional virtualized solutions. This work provides insights into optimizing edge infrastructures, enabling more efficient and specialized deployment strategies for diverse application workloads.

Exploring the Viability of Unikernels for ARM-powered Edge Computing

The rapid expansion of IoT devices and their real-time applications have driven a growing need for edge computing. To meet this need, efficient and secure solutions are required for running such applications on resource-constrained devices with limited power, CPU, and memory. Unikernel, with its minimalistic design and application-specific approach, offers a promising alternative to traditional virtualization and container technologies in these environments. The existing research does not thoroughly examine the feasibility of using unikernel for edge computing. This paper investigates the potential of unikernel for ARM-powered edge computing by evaluating the performance and efficiency of three prominent unikernel systems such as OSv, Nanos, and Unikraft against Docker container. We experiment with real-world edge computing applications and utilize key metrics such as boot time, execution time, memory usage, CPU overhead, and network performance to determine how unikernel performs under the constraints of edge devices. Our findings reveal the potential advantages of unikernel in terms of reduced resource consumption and faster startup times while highlighting areas where they may need further optimization for edge deployment. This study provides valuable insights for researchers and practitioners considering unikernel as a lightweight, efficient solution for edge computing on ARM architectures.

LUCID: A Framework for Reducing False Positives and Inconsistencies Among Container Scanning Tools

Containerization has emerged as a revolutionary technology in the software development and deployment industry. Containers offer a portable and lightweight solution that allows for packaging applications and their dependencies systematically and efficiently. In addition, containers offer faster deployment and near-native performance with isolation and security drawbacks compared to Virtual Machines. To address the security issues, scanning tools that scan containers for preexisting vulnerabilities have been developed, but they suffer from false positives. Moreover, using different scanning tools to scan the same container provides different results, which leads to inconsistencies and confusion. Limited work has been done to address these issues. This paper provides a fully functional and extensible framework named LUCID that can reduce false positives and inconsistencies provided by multiple scanning tools. We use a database-centric approach and perform query-based analysis, to pinpoint the causes for inconsistencies. Our results show that our framework can reduce inconsistencies by 70%. The framework has been tested on both Intel64/AMD64 and ARM architecture. We also create a Dynamic Classification component that can successfully classify and predict the different severity levels with an accuracy of 84%. We believe this paper will raise awareness regarding security in container technologies and enable container scanning companies to improve their tool to provide better and more consistent results.
